Over the past 60 years, clinical nutrition has evolved into a key technology for saving the lives of patients with intestinal failure or complex diseases. However, the 21st century has seen issues with adverse outcomes due to a lack of timely and effective nutritional screening and intervention. Despite the benefits of minimally invasive surgery, nutritional risks or adverse outcomes still exceed 50% in gastrointestinal surgery. The study explores the importance of comprehensive nutritional management for surgical patients, beginning with a reevaluation of their nutritional risks and malnutrition, especially in the context of increasing chronic diseases like cancer, elderly comorbidities, and inflammatory bowel disease. It emphasizes the importance of clinical nutrition guidelines and consensus in surgical practice validated by various studies. The article then details the comprehensive nutritional management of surgical patients, including the importance of nutritional risk screening, assessment, diagnosis, and nutritional support treatment, especially during the early and recovery phases of major gastrointestinal surgery. The aim is to enhance the awareness of surgeons and healthcare workers about nutritional management to improve patients' clinical outcomes and quality of life.

ObjectiveTo explore the syndrome elements and evolving patterns of patients with hepatitis B virus-related acute on chronic liver failure （HBV-ACLF） at different stages. MethodsClinical information of 1,058 hospitalized HBV-ACLF patients， including 618 in the early stage， 355 in the middle stage， and 85 in the late stage， were collected from 18 clinical centers across 12 regions nationwide from January 1， 2012 to February 28， 2015. The “Hepatitis B-related Chronic and Acute Liver Failure Chinese Medicine Clinical Questionnaire” were designed to investigate the basic information of the patients， like the four diagnostic information （including symptoms， tongue， pulse） of traditional Chinese medicine （TCM）， and to count the frequency of the appearance of the four diagnostic information. Factor analysis and cluster analysis were employed to determine and statistically analyze the syndrome elements and patterns of HBV-ACLF patients at different stages. ResultsThere were 76 four diagnostic information from 1058 HBV-ACLF patients， and 53 four diagnostic information with a frequency of occurrence ≥ 5% were used as factor analysis entries， including 36 symptom information， 12 tongue information， and 5 pulse information. Four types of TCM patterns were identified in HBV-ACLF， which were liver-gallbladder damp-heat pattern， qi deficiency and blood stasis pattern， liver-kidney yin deficiency pattern， and spleen-kidney yang-deficiency pattern. In the early stage， heat （39.4%， 359/912） and dampness （27.5%， 251/912） were most common， and the pattern of the disease was dominated by liver-gallbladder damp-heat pattern （74.6%， 461/618）； in the middle stage， dampness （30.2%， 187/619） and blood stasis （20.7%， 128/619） were most common， and the patterns of the disease were dominated by liver-gallbladder damp-heat pattern （53.2%， 189/355）， and qi deficiency and blood stasis pattern （27.6%， 98/355）； and in the late stage， the pattern of the disease was dominated by qi deficiency （26.3%， 40/152） and yin deficiency （20.4%， 31/152）， and the patterns were dominated by qi deficiency and blood stasis pattern （36.5%， 31/85）， and liver-gallbladder damp-heat pattern （25.9%， 22/85）. ConclusionThere are significant differences in the distribution of syndrome elements and patterns at different stages of HBV-ACLF， presenting an overall trend of evolving patterns as "from excess to deficiency， transforming from excess to deficiency"， which is damp-heat → blood stasis → qi-blood yin-yang deficiency.

The second plenary session of the 20th Central Commission for Discipline Inspection proposed the"develop-ment of a five-year plan for information technology construction to establish a digital disciplinary inspection and supervision system that covers the entire process and all elements."This provides guidance and momentum for disciplinary inspection agencies at all levels to implement the strategic deployment of the Party's 20th National Congress regarding comprehensive and strict governance of the Party.In this context,utilizing information technology to enhance the efficiency of supervision,discipline enforcement,and accountability while ensuring the high-quality development of public hospitals has become a key task for their disciplinary inspec-tion departments.The Disciplinary Inspection Commission of a public hospital has explored the establishment of a disciplinary in-spection management platform to achieve modular management of inspection tasks.By utilizing functions such as task allocation,statistical analysis,data migration,and early warning reminders,the platform aims to improve the efficiency of disciplinary in-spection work.This approach helps address the challenges of heavy workloads and limited inspection resources in hospitals,enab-ling real-time supervision,early warning correction,and time-bound oversight,thereby providing strong support for the construc-tion of integrity in the hospital.

Objective:We aimed to develop a novel visualized model based on nomogram to predict postoperative overall survival.Methods:This was a multicenter, retrospective, observational cohort study, including participants with histologically confirmed gastric and colorectal cancer who underwent radical surgery from 11 medical centers in China from August 1, 2015 to June 30, 2018. Baseline characteristics, histopathological data and nutritional status, as assessed using Nutrition Risk Screening 2002 (NRS 2002) score and the scored Patient-Generated Subjective Global Assessment, were collected. The least absolute shrinkage and selection operator regression and Cox regression were used to identify variables to be included in the predictive model. Internal and external validations were performed.Results:There were 681 and 127 patients in the training and validation cohorts, respectively. A total of 188 deaths were observed over a median follow-up period of 59 (range: 58 to 60) months. Two independent predictors of NRS 2002 and Tumor-Node-Metastasis (TNM) stage were identified and incorporated into the prediction nomogram model together with the factor of age. The model's concordance index for 1-, 3- and 5-year overall survival was 0.696, 0.724, and 0.738 in the training cohort and 0.801, 0.812, and 0.793 in the validation cohort, respectively.Conclusions:In this study, a new nomogram prediction model based on NRS 2002 score was developed and validated for predicting the overall postoperative survival of patients with gastric colorectal cancer. This model has good differentiation, calibration and clinical practicability in predicting the long-term survival rate of patients with gastrointestinal cancer after radical surgery.

Artificial intelligence has gradually become an important tool in the field of clinical nutrition. Artificial intelligence can not only simplify the current dietary assessment methods, but also develop nutritional assessment models with favorable accuracy through machine learning. Digital technologies and devices such as mobile applications and wearable devices have expanded the accessibility of dietary nutritional assessment. Mobile applications can be used for convenient and quick dietary nutritional assessment based on food images and videos, with real-time output of the types and amount of nutrients. Wearable devices can provide real-time feedback of individual dynamic nutrient intake and absorption by monitoring the fluctuation of the levels of biomarkers in body fluids. Nutritional assessment based on machine learning can improve the accuracy of malnutrition diagnosis, predict adverse events such as enteral nutrition intolerance, and guide nutritional intervention and prognosis prediction.

BACKGROUND/OBJECTIVES: This study aimed to investigate cancer-specific survival (CSS) and associated risk factors in elderly gastric cancer (EGC) patients. SUBJECTS/METHODS: EGC patients (≥ 70 yrs) who underwent curative gastrectomy between January 2013 and December 2017 at our hospital were included. Clinicopathologic characteristics and survival data were collected. Receiver operating characteristic (ROC) analysis was used to extract the best cutoff point for body mass index (BMI). A Cox proportional hazards model was used to determine the risk factors for CSS. RESULTS: In total, 290 EGC patients were included, with a median age of 74.7 yrs. The median follow-up time was 31 (1–77) mon. The postoperative 1-yr, 3-yr and 5-yr CSS rates were 93.7%, 75.9% and 65.1%, respectively. Univariate analysis revealed risk factors for CSS, including age (hazard ratio [HR] = 1.08; 95% confidence interval [CI], 1.01–1.15), intensive care unit (ICU) admission (HR = 1.73; 95% CI, 1.08–2.79), nutritional risk screening (NRS 2002) score ≥ 5 (HR = 2.33; 95% CI, 1.49–3.75), and preoperative prognostic nutrition index score < 45 (HR = 2.06; 95% CI, 1.27–3.33). The ROC curve showed that the best BMI cutoff value was 20.6 kg/m 2 . Multivariate analysis indicated that a BMI ≤ 20.6 kg/m 2 (HR = 2.30; 95% CI, 1.36–3.87), ICU admission (HR = 1.97; 95% CI, 1.17–3.30) and TNM stage (stage II: HR = 5.56; 95% CI, 1.59–19.43; stage III: HR = 16.20; 95% CI, 4.99–52.59) were significantly associated with CSS. CONCLUSIONS Low BMI (≤ 20.6 kg/m2 ), ICU admission and advanced pathological TNM stages (II and III) are independent risk factors for CSS in EGC patients after curative gastrectomy. Nutrition support, better perioperative management and early diagnosis would be helpful for better survival.

Non-small cell lung cancer (NSCLC) is the most common pathological type of lung cancer. The systemic antitumor therapy of advanced NSCLC has undergone renovations of chemotherapy, targeted therapy and immunotherapy, which results in greatly improved survival for patients with advanced NSCLC. Immune checkpoint inhibitors (ICIs), especially targeting programmed cell death protein 1 (PD-1)/programmed death-ligand 1 (PD-L1), has changed the treatment paradigm of NSCLC. ICIs have become the standard treatment for advanced NSCLC without epidermal growth factor receptor(EGFR) mutation or anaplastic lymphomakinase(ALK) translocation in the first- or second-line setting, and for locally advanced NSCLC following concurrent radiotherapy and chemotherapy. ICIs are also promising in adjuvant/neoadjuvant therapy. More and more ICIs have been approved domestically for the treatment of NSCLC. Led by the NSCLC expert committee of Chinese Society of Clinical Oncology (CSCO), this consensus was developed and updated based on thoroughly reviewing domestic and foreign literatures, clinical trial data, systematic reviews, experts' discussion and the consensus(2019 version). This consensus will aid domestic clinicians in the treatment of NSCLC with ICIs.

Cardio-cerebrovascular disease (CCVD) is a major comorbidity of Coronavirus disease 2019 (COVID-19). However, the clinical characteristics and outcomes remain unclear. In this study, 102 cases of COVID-19 from January 22, 2020 to March 26, 2020 in Xixi Hospital of Hangzhou were included. Twenty cases had pre-existing CCVD. Results showed that compared with non-CCVD patients, those with CCVD are more likely to develop severe disease (15% versus 1%), and the proportion of pneumonia severity index grade IV was significantly higher (25% versus 3.6%). Computed tomography images demonstrated that the proportion of multiple lobe lesion involvement was significantly higher in the CCVD group than in the non-CCVD group (90% versus 63.4%). Compared with non-CCVD group, the levels of C-reactive protein, fibrinogen, D-dimer, and serum amyloid-A were higher, whereas the total protein and arterial partial PaO

Objective:To investigate the risk factors for early complications after laparoscopy-assisted gastrectomy in patients with gastric cancer.Methods:The retrospective case-control study was conducted. The clinicopathological data of 196 patients who underwent laparos-copy-assisted radical gastrectomy at Peking Union Medical College Hospital from March 2016 to March 2019 were collected. There were 144 males and 52 females, aged (61±10)years. Observation indicators: (1) early complications after laparoscopy-assisted radical gastrectomy and treatment; (2) analysis of risk factors for early complications after laparoscopy-assisted radical gastrectomy.Measurement data with normal distribution were represented as Mean± SD, and measurement data with skewed distribution were represented as M( P25,P75). Count data were represented as absolute numbers. Univariate analysis was conducted using the t test, Mann-Whitney U test or chi-square test. Multivariate analysis was conducted using the Logistic regressional model. Results:(1) Early complications after laparoscopy-assisted radical gastrectomy and treatment: 51 of 196 patients had early postoperative complications, including 7 cases of grade Ⅰ according to Clavien-Dindo classi-fication system, 32 cases of grade Ⅱ, 9 cases of grade Ⅲa, 3 cases of grade Ⅲb. There was no grade Ⅳ or Ⅴ complication. There were 25 cases with abdominal complications, 7 cases with thoracic complications, 3 cases with internal/catheter related complications and 16 cases with other unclassified complications. All patients with complications were improved after symptomatic and supportive treatments. (2) Analysis of risk factors for early complications after laparoscopy-assisted radical gastrectomy: results of univariate analysis showed that the lymphocyte count, neutrophil-to-lymphocyte ratio, radiotherapy, operation time, volume of intraoperative blood loss, T stage, lymph node metastasis were related factors for early complications after laparoscopy-assisted radical gastrectomy in patients with gastric cancer ( Z=?2.048, χ2=6.385, 4.168, 8.068, 6.336, 12.497, 7.522, P<0.05). Results of multivariate analysis showed that the neutrophil/lymphocyte ratio ≥1.96, operation time ≥222 minutes, and lymph node metastasis were independent risk factors for early complica-tions after laparoscopy-assisted radical gastrectomy in patients with gastric cancer ( odds ratio=2.279, 2.245, 2.226, 95% confidence interval as 1.149-4.519, 1.116-4.517, 1.125-4.402, P<0.05). Conclusions:The abdominal complications are the most common early complications after laparoscopy-assisted radical gastrectomy. The neutrophil-to-lymphocyte ratio ≥1.96, operation time ≥222 minutes, and lymph node metastasis are independent risk factors for early complications after laparoscopy-assisted radical gastrectomy in patients with gastric cancer.

To compare changes in platelet related parameters in obese patients before and after sleeve gastrectomy (SG), we retrospectively analyzed the clinical data of 31 obese patients who underwent SG in Peking Union Medical College Hospital from December 2012 to September 2020. Results showed that compared with those before surgery, platelet count (PLT) decreased significantly at 2-12 weeks of follow-up ( P=0.009), while platelet distribution width (PDW), mean platelet volume (MPV), and large platelet ratio (P-LCR) increased significantly at the same periods of follow-up after operation ( P<0.001). However, the levels of PDW, MPV, and P-LCR began to decrease at 16-55 weeks when compared with those at 2-12 weeks of follow-up ( P<0.01). PLT was positively correlated with white blood cells and neutrophils at 2-12 weeks of follow-up and positively correlated with high sensitivity C-reactive protein at 16-55 weeks of follow-up after operation ( P<0.05).
