Histological subtype plays an important role in the different clinical characteristics and survival outcomes of patients with colorectal carcinoma (CRC). However, in previous studies, the influences of tumor locations and tumor stages have not been strictly controlled. This study focused on the assessment of the prognostic value of each histological subtype in different tumor locations and tumor stages of CRC. We used the Surveillance, Epidemiology, and End Results (SEER) database (1973–2011) to analyze 818,229 CRC patients with different clinical and pathological features, and analyzed the prognostic value of each histological subtype. Under the condition of stratification by tumor stage, signet-ring cell carcinoma (SRCC) presented the worst survival in each stage of right colon cancer (stage I, log-rank, p = 0.002, stages II, III, and IV, log-rank, p < 0.001), rectal cancer (RC) (log-rank, p < 0.001), and in stages II, III, and IV of left colon cancer (log-rank, p < 0.001). Multivariate survival analysis suggested SRCC subtype, male gender, age ≥ 70 years, tumor size ≥ 5 cm, stage progression, and poor differentiation were all significant factors worsening survival in CRC (p < 0.001, respectively). Mucinous adenocarcinoma (MC) histological subtype proved to be an independent protective factor for the prognosis of right colon cancer (p = 0.003). Overall, in our study, the results suggested SRCC had the worst survival among the three histological subtypes of CRC. MC was associated with favorable prognosis in right colon cancer but not with other tumor locations.

Background: Early enteral nutrition (EN) after abdominal surgery can improve the prognosis of patients. However, the high feeding intolerance (FI) rate is the primary factor impeding postoperative EN. Methods: Sixty-seven patients who underwent radical subtotal or total gastrectomy for gastric cancer (GC) were randomly allocated to the preoperative oral nutritional supplement group (ONS group) or dietary advice alone (DA group). Both groups were fed via nasojejunal tubes (NJs) from the first day after surgery to the fifth day. The primary endpoint is the FI rate. Results: Of the patients, 66 completed the trial (31 in the ONS group, 35 in the DA group). The FI rate in the ONS group was lower than that in the DA group (25.8% vs. 31.4%, p = 0.249). The postoperative five-day 50% energy compliance rate in the ONS group was higher than that in the DA group (54.8% vs. 48.6%, p = 0.465). The main gastrointestinal intolerance symptoms were distension (ONS vs. DA: 45.2% vs. 62.9, p = 0.150) and abdominal pain (ONS vs. DA: 29.0% vs. 45.7%, p = 0.226). Postoperative nausea/vomiting rate and heartburn/reflux rate were similar between the two groups. We noted no difference in perioperative serum indices, short-term prognosis or postoperative complication rates between the two groups. Conclusions: The study shows that short-term preoperative ONS cannot significantly improve FI and the energy compliance rate in the early stage after radical gastrectomy.

Sarcopenia is a syndrome characterized by a progressive, widespread decline in muscle mass and strength. DEHP, a plasticizer involved in daily life and widely used, has been found in various everyday items and causes developmental dysregulation, reproductive impairments, tumorigenesis, and transgenerational disease. However, much remains to be discovered regarding the association between exposure to this environmental toxin and sarcopenia, as well as the toxic targets and molecular mechanisms. This research elucidated the relationship between contact with DEHP and the development of sarcopenia by integrating NHANES data analysis, network toxicology, and molecular docking. 3199 adults were enrolled, and multiple linear regressions were performed to reveal a significant negative correlation between lnDEHP and ALM_BMI. Eighty-eight targets associated with DEHP and sarcopenia were identified. Subsequent STRING and Cytoscape screening stressed 20 key targets, including CASP3, BCL2, MMP9, BCL2L1, APP, and CTSS. GO and KEGG enrichment analyses revealed that these targets are involved in ligand-receptor interactions, apoptosis, and calcium signaling pathways. Molecular docking simulations using CB-dock confirmed the high-affinity binding interactions between DEHP and these key targets. This study validated the relationship between DEHP exposure and muscle mass. Further, it provided a theoretical basis for investigating the molecular mechanisms of DEHP exposure-induced skeletal muscle toxicity.

The ZJU index is an innovative computational method which integrates BMI, FBG, TG, and ALT to AST ratio. It strongly correlates with measures of lipid metabolism and glucose intolerance. No researches have yet explored the relationship between the ZJU index and sarcopenia. We analyzed NHANES data from 2011 to 2018, dividing the ZJU index into quartiles. The association was investigated by adjusting for confounders using multivariable linear and logistic regression analysis. Results were visualized through RCS regression and threshold effect analyses. We conducted various subgroup and sensitivity analyses and plotted ROC curves to assess prediction efficacy, with the AUC as the measure of accuracy. As the ZJU index increases, the prevalence of sarcopenia also rises. Following the control of potential confounders via logistic regression analysis, our research identified a distinct relationship between the ZJU index and sarcopenia, which was statistically significant (P < 0.001), with higher ZJU index values associated with increased risk (OR = 12.40, 95% CI: 8.46–18.17). Interaction analysis suggests that the relationship between the ZJU index and the risk of developing sarcopenia varies significantly between males and females across different ZJU index levels. ROC analysis for the ZJU index shows an AUC of 0.749. Conclusions: The ZJU index significantly correlates with a heightened risk of sarcopenia in Americans, suggesting its potential as a predictive marker for sarcopenia.

The ratio between non-high-density lipoprotein cholesterol and high-density lipoprotein cholesterol (NHHR) is a reliable marker for assessing the risk linked to lipid metabolism disorders. Sarcopenia, characterized by age-related loss of muscle mass and strength/function, includes the assessment of muscle mass, muscle strength, and muscle-specific strength. However, research into NHHR’s relationship with low muscle mass risk remains unexplored. Our study utilized a cross-sectional approach, examining data derived from the National Health and Nutrition Examination Survey (NHANES) from 2011 to 2018. Through multivariable linear and logistic regression, we investigated the relationships of the NHHR with muscle mass and low muscle mass. We visualized the results using smoothing curves and assessed threshold effects. We also performed various subgroup and sensitivity analyses. This research encompassed 9,012 participants and demonstrated significant nonlinear associations between NHHR and ALMBMI or low muscle mass risk in a generalized additive model (GAM), pinpointing critical NHHR values (3.328 and 3.367) where changes in NHHR significantly impacted ALMBMI and low muscle mass risk. The NHHR demonstrates a significant association with an increased risk of low muscle mass among middle-aged Americans. This ratio has potential as a predictive marker for low muscle mass. Further exploration of NHHR is expected to aid in advancing preventive and therapeutic measures for this condition.

Background: Patients with gastrointestinal cancer often suffer from malnutrition during tumor progression. Malnutrition is associated with postoperative complications and decreased quality of life. Supporting cancer patients with proper nutrition is vital for improving their prognoses. Method: Google scholar and PubMed database searches were performed. Selection criteria included gastrointestinal cancer, surgery, ω − 3 fatty acids, randomized clinical trials from 2007 to August 2022. Conclusion: Nutritional therapy includes nutritional counseling, enteral nutrition, parenteral nutrition, and oral nutritional supplements. Immune nutrients like glutamine and ω-3 fatty acid have been demonstrated with benefits in reducing inflammatory responses and postoperative complications, regulating immune function and improving prognosis.
