Copper, an indispensable trace element for the human body, serves not only as a crucial auxiliary factor in redox reactions within the organism but also as a significant constituent of numerous key metabolic enzymes. The COMMD family plays a vital role in regulating copper at both the cellular and systemic levels, particularly in the realm of tumor research, an area notably deficient in gastric cancer investigations. With the advancement of precision medical techniques, individualized and precise screening and treatment have become paramount considerations in the contemporary medical landscape for gastric cancer therapy. In light of this, we meticulously scrutinized existing transcriptomic datasets for gastric cancer, validating the expression levels and prognostic value of COMMD family genes. Simultaneously, employing the ssGSEA algorithm, we devised the COMMDs score. Enrichment analysis, gene mutations, and clinical features were incorporated into the assessment of this score. Furthermore, we contextualized the COMMDs score within the framework of the immune microenvironment, evaluating the relationship between the COMMDs family and immune factors as well as immune cells. The results suggest a correlation between the COMMDs score and various immune-related features. Based on this foundation, multiple machine learning approaches indicated Logistic Regression, with a remarkable ROC of 0.972, as the optimal diagnostic model. To accentuate the translational medical value of the COMMDs family, we selected COMMD10 as a differential gene in gastric cancer for further validation. Functional experiments revealed a decline in the proliferative and migratory capabilities of gastric cancer cells upon silencing COMMD10. Additionally, through pathway intervention, we unveiled the PI3K-AKT pathway as a potential mechanism through which COMMD10 influences gastric cancer activity. In summary, our study affirms the prospective role of the COMMDs family as potential markers for the diagnosis and treatment of gastric cancer in the future.

Postsurgical patients’ oral feeding begins with clear fluids 1–3 days after surgery. This might not be sufficiently nutritious to boost the host immune system and provide sufficient energy in gastric neoplastic patients to achieve the goal of enhanced recovery after surgery (ERAS). Our objective was to analyze the significance of early postoperative feeding tubes in boosting patients’ immunity and decreasing incidence of overall complications and hospital stay in gastric cancer patients’ post-gastrectomy. From January 2005 to May 24, 2019, PubMed and Cochrane databases were searched for studies involving enteral nutrition (EN) feeding tubes in comparison to parenteral nutrition (PN) in gastric cancer patients undergoing gastrectomy for gastric malignancies. Relative risk (RR), mean difference (MD), or standard mean difference (SMD) with 95% confidence interval (CI) were used to estimate the effect sizes, and heterogeneity was assessed by using Q and χ2 statistic with their corresponding P values. All the analyses were performed with Review Manager 5.3 and SPSS version 22. Nine randomized trials (n = 1437) and 5 retrospective studies (n = 421) comparing EN feeding tubes and PN were deemed eligible for the pooled analyses, with a categorized time frame of PODs ≥ 7 and PODs < 7. Ratio of CD4+/CD8+ in EN feeding tubes was the only outcome of PODs < 7, which showed significance (MD 0.22, 95% CI 0.18–0.25, P < 0.00001). Regarding other immune indicators, significant outcomes in favor of EN feeding tubes were measured on POD ≥ 7: CD3+ (SMD 1.71; 95% CI 0.70, 2.72; P = 0.0009), CD4+ (MD 5.84; 95% CI 4.19, 7.50; P < 0.00001), CD4+/CD8+ (MD 0.28; 95% CI 0.20; 0.36, P < 0.00001), NK cells (SMD 0.94; 95% CI 0.54, 1.30; P < 0.00001), nutrition values, albumin (SMD 0.63; 95% CI 0.34, 0.91; P < 0.001), prealbumin (SMD 1.00; 95% CI 0.52, 1.48; P < 0.00001), and overall complications (risk ratio 0.73 M-H; fixed; 95% CI 0.58, 0.92; P = 0.006). EN feeding tube support is an essential intervention to elevate patients’ immunity, depress levels of inflammation, and reduce the risk of complications after gastrectomy for gastric cancer. Enteral nutrition improves the innate immune system and nutrition levels but has no marked significance on certain clinical outcomes. Also, EN reduces the duration of hospital stay and cost, significantly.

Patients bearing liver metastasis of pancreatic adeno carcinoma (PDAC) suffer from poor prognosis due to its short duration and high mortality. Complex tumor microenvironment (TME) exists in liver metastatic niches, and tumor-associated macrophages (TAMs) have play vital roles in metastasis generation and outgrowth. We have discovered that M2 type TAM-derived SEMA5A could bind to its tumor cell-expressed receptor PLXNB3 to promote tumor cell proliferation and outgrowth. We utilized liver metastasis samples of PDAC patients, intrasplenic injection mouse models, and Kras^G12D/Trp53^R172H/Pdx1-Cre (KPC) mouse models for in vivo study. In mechanism investigation, we have discovered that SEMA5A-PLXNB3 axis could achieve tumor cell proliferation and survival via enhancing aerobic glycolysis termed as the Warburg effects. Targeting this axis may be a potential therapeutic approach for PDAC patients with unresectable liver metastasis.

Background: With the use of cobalt alloys in medical prosthetics, the risk of cobalt exposure has increased. The objective of this study was to investigate the correlation between blood cobalt levels and the occurrence of gallstones utilizing data from the National Health and Nutrition Examination Survey (NHANES).Methods: Data collected between 2017 and 2020 were analyzed, encompassing a total of 5,610 participants. Cobalt concentrations in whole blood specimens were directly measured using inductively coupled plasma mass spectrometry (ICP-MS). The presence of gallstones was ascertained through a standardized questionnaire. To assess the association between blood cobalt levels and the presence of gallstones, logistic regression analysis, restricted cubic spline analysis, and subgroup analysis were utilized.Results: The results of logistic regression analysis revealed a heightened risk of developing gallstones in the Quartiles 2 and Quartiles 4 groups based on blood cobalt levels when compared to the Quartiles 1 group (OR = 1.54, 95% CI: 1.15–2.07; OR = 1.35, 95% CI: 1.03–1.77). The restricted cubic spline analysis exhibited a positive linear correlation between blood cobalt levels and the occurrence of gallstones. Subgroup analyses further demonstrated a statistically significant correlation between the Quartiles 4 category of blood cobalt levels and an elevated risk of gallstones, particularly among individuals aged 60 years or older, females, those with a body mass index (BMI) equal to or exceeding 25, serum total cholesterol levels below 200 mg/dL, as well as individuals diagnosed with hypertension or diabetes.Conclusion: Our study findings indicate a notable association between elevated blood cobalt levels and an increased risk of gallstones. To establish a causal relationship between blood cobalt levels and the elevated risk of developing gallstones, further prospective cohort studies are warranted.

Background and objectives: Enhanced recovery after surgery (ERAS) recommends avoiding enteral nutrition (EN) due to undesirable sequelae such as pulmonary aspiration and infections. Not using of EN in nongastric resections under ERAS pathways is often successful. However, parenteral nutrition (PN) alone followed by early postoperative oral feeding in gastric cancer patients, recommended by the ERAS guidelines, has unclear benefit and is only adopted after gastric resection. This study aimed to compute the postoperative outcomes of EN and PN compared to those of the ERAS-recommended nutritional pathway. Our secondary objective was to compare postoperative complications between the two groups. Materials and methods: Of 173 gastrectomy patients, 116 patients were in the combined group (EN and PN), whereas 57 patients were in the PN alone group. Statistical analysis was performed with the Statistical Package for the Social Sciences (SPSS) version 26.0.0 software. The data were analyzed by one-way ANOVA, the independent sample t-test, or, in the case of several independent samples, by the Kruskal–Wallis test. Categorical data were analyzed by Pearson’s χ² test or Fisher’s exact test. Results: The observed indices included C-reactive protein (CRP), platelet (PLT), white blood cells (WBC), hemoglobin (Hb), albumin, and PRE-albumin. The secondary outcomes included length of hospital stay (LOS), cost, incidence of pulmonary infection, and total incidence of infection. Conclusion: The combined mode of nutrition is feasible and is not associated with postoperative complications in gastric cancer patients under ERAS.

This study aimed to analyze the clinical efficacy of π-shaped esophagojejunostomy and the overlap method in treating upper gastric cancer with double-tract reconstruction in proximal gastrectomy under total laparoscopy. Clinical data were collected from patients with upper gastric cancer who underwent surgery in the General Surgery Department of Jiangsu University Affiliated Hospital from June 1, 2017, to January 1, 2023. Patients were categorized into the overlap method group and the π-shaped esophagojejunostomy group. We collected perioperative and gastroscopy follow-up data from both groups 1 year after surgery. Seventy-nine patients were included, with 46 in the overlap anastomosis group and 33 in the π-shaped esophagojejunostomy group. Both groups were evaluated for age, sex, body mass index, tumor diameter, tumor pathological Tumor, Node, Metastasis staging, intraoperative bleeding volume, number of lymph node dissections, postoperative hospitalization days, postoperative hospitalization days, catheter removal time, drainage tube removal time, recovery time, anal defecation time, postoperative bedtime activity time, hospitalization cost, Visual Analog Scale (VAS) score at rest on the first day after surgery, VAS score at activity on the first day after surgery, short-term postoperative complications and 1-year gastroscopy follow-up. No significant difference was observed in these factors (P > 0.05). However, the π-shaped esophagojejunostomy group had a significantly lower surgical time and anastomosis time than the overlap anastomosis group (P < 0.05). Both overlap anastomosis and π-shaped esophagojejunostomy are safe for double-tract reconstruction in proximal gastrectomy under total laparoscopy without increasing the incidence of perioperative and short-term complications in patients. π-shaped esophagojejunostomy has shorter surgical time and anastomosis time than overlap anastomosis.
