The Effect of Different Nutritional Nursing Support on the Nutritional Status and Disease Recovery of Elderly Patients with Gastrointestinal Tumors during the Perioperative Period

Advances in the diagnosis and treatment of MET-variant digestive tract tumors

The receptor tyrosine kinase encoded by the MET gene plays an important role in various cellular processes such as growth, survival, migration and angiogenesis, and its abnormal activation is closely related to the occurrence and development of various tumors. This article reviews the recent advances in diagnosis and treatment of MET-variant digestive tract tumors. In terms of diagnosis, the application of next-generation sequencing technology and liquid biopsy technology makes the detection of MET variants more accurate and efficient, providing a reliable basis for individualized treatment. In terms of treatment, MET inhibitors such as crizotinib and cabotinib have shown good efficacy in clinical trials. In addition, the combination of immunotherapy and MET inhibitors also demonstrated potential synergies, further improving the therapeutic effect. However, the complexity and heterogeneity of drug resistance mechanisms are still one of the difficulties in current research. In the future, it is necessary to further deepen the understanding of the mechanism of MET variation and explore new combination treatment strategies to improve the overall survival rate and quality of life of patients. The diagnosis and treatment of MET-variant digestive tract tumors are moving towards precision and individualization, and have broad application prospects.

Gastroenteropancreatic neuroendocrine neoplasms: current development, challenges, and clinical perspectives

Neuroendocrine neoplasms (NENs) are highly heterogeneous and potentially malignant tumors arising from secretory cells of the neuroendocrine system. Gastroenteropancreatic neuroendocrine neoplasms (GEP-NENs) are the most common subtype of NENs. Historically, GEP-NENs have been regarded as infrequent and slow-growing malignancies; however, recent data have demonstrated that the worldwide prevalence and incidence of GEP-NENs have increased exponentially over the last three decades. In addition, an increasing number of studies have proven that GEP-NENs result in a limited life expectancy. These findings suggested that the natural biology of GEP-NENs is more aggressive than commonly assumed. Therefore, there is an urgent need for advanced researches focusing on the diagnosis and management of patients with GEP-NENs. In this review, we have summarized the limitations and recent advancements in our comprehension of the epidemiology, clinical presentations, pathology, molecular biology, diagnosis, and treatment of GEP-NETs to identify factors contributing to delays in diagnosis and timely treatment of these patients.

Substandard feeding in children undergoing mechanical ventilation in pediatric intensive care unit: A retrospective cohort study in China

Background

Enteral nutrition is a common yet vital practice in the pediatric intensive care unit (PICU). However, the status of substandard feeding of enteral nutrition in PICU children undergoing mechanical ventilation remains unclear and can be detrimental to the children's prognosis.

Objective

This study aimed to evaluate the incidence, nursing care status, and influencing factors of substandard feeding in children undergoing mechanical ventilation in the PICU.

Methods

This study employed a retrospective cohort design. Children undergoing mechanical ventilation and enteral nutrition in the PICU of a public hospital in China from 1 June 2021 to 31 December 2022 were selected using convenience sampling, and their characteristics were collected and evaluated. Pearson correlation analysis and multivariate logistic regression analysis were conducted to assess the influencing factors of substandard feeding in PICU children with mechanical ventilation.

Results

A total of 156 PICU children undergoing mechanical ventilation were included for analysis in this study. The rate of substandard feeding in PICU children was 65.38%. Statistically significant differences were observed in diarrhea, vomiting, the use of sedatives, and average infusion speed between the substandard feeding group and the standard group (p <0.05). Pearson correlation results indicated that diarrhea (r = 0.595), vomiting (r = 0.602), and average infusion speed (r = 0.562) were correlated with substandard feeding and characteristics of included ICU children undergoing mechanical ventilation (p <0.05). Logistic regression results found that diarrhea (OR = 2.183, 95%CI: 1.855~2.742), vomiting (OR = 3.021, 95%CI: 2.256~4.294), and average infusion speed ≤40 mL/h (OR = 2.605, 95%CI: 1.921~3.357) were independent risk factors for substandard feeding in mechanically ventilated children in the ICU (p <0.05).

Conclusion

The rate of substandard feeding in children with mechanical ventilation in the PICU was high. Diarrhea, vomiting, and slow infusion speed are important influencing factors for substandard feeding. It is suggested that nurses and other healthcare professionals take targeted measures, including the prevention and care of diarrhea and vomiting, as well as monitoring and adjusting the infusion speed of enteral nutrition, to reduce the occurrence of substandard feeding.
