OBJECTIVES: To explore the risk factors of feeding intolerance (FI) in critically ill children receiving enteral nutrition (EN) and to construct a prediction nomogram model for FI. METHODS: A retrospective study was conducted to collect data from critically ill children admitted to the Pediatric Intensive Care Unit of Xiangya Hospital, Central South University, between January 2015 and October 2020. The children were randomly divided into a training set (346 cases) and a validation set (147 cases). The training set was further divided into a tolerance group (216 cases) and an intolerance group (130 cases). Multivariate logistic regression analysis was used to screen for risk factors for FI in critically ill children receiving EN. A nomogram was constructed using R language, which was then validated on the validation set. The model's discrimination, calibration, and clinical net benefit were evaluated using receiver operating characteristic curves, calibration curves, and decision curves. RESULTS: Duration of bed rest, shock, gastrointestinal decompression, use of non-steroidal anti-inflammatory drugs, and combined parenteral nutrition were identified as independent risk factors for FI in critically ill children receiving EN (P<0.05). Based on these factors, a nomogram prediction model for FI in critically ill children receiving EN was developed. The area under the receiver operating characteristic curve for the training set and validation set was 0.934 (95%CI: 0.906-0.963) and 0.852 (95%CI: 0.787-0.917), respectively, indicating good discrimination of the model. The Hosmer-Lemeshow goodness-of-fit test showed that the model had a good fit (χ 2=12.559, P=0.128). Calibration curve and decision curve analyses suggested that the model has high predictive efficacy and clinical application value. CONCLUSIONS Duration of bed rest, shock, gastrointestinal decompression, use of non-steroidal anti-inflammatory drugs, and combined parenteral nutrition are independent risk factors for FI in critically ill children receiving EN. The nomogram model developed based on these factors exhibits high predictive efficacy and clinical application value.

OBJECTIVE: To investigate the current status and influencing factors of feeding intolerance (FI) during enteral nutrition (EN) in intensive care unit (ICU) patients. METHODS: A retrospective case-control study was conducted, including patients from two ICU wards of a tertiary hospital in Guizhou Province from July 2019 to December 2022. Clinical data were collected using a self-designed data collection form, including general information [age, gender, acute physiology and chronic health evaluation II (APACHE II)], clinical treatment (mechanical ventilation, mild hypothermia therapy), medication use (vasoactive drugs, glucocorticoids, analgesics, sedatives), EN implementation (types of EN fluids, EN methods, tube feeding rate), EN tolerance, and blood glucose status. Patients were divided into EN tolerance and EN intolerance groups based on the FI criteria. Differences in the above-mentioned indicators between the two groups were compared, and statistically significant indicators were included in a binary multivariate Logistic regression analysis to explore the independent influencing factors of FI during EN in ICU patients. RESULTS: A total of 683 ICU patients were included, with 57.10% (390/683) incidence of FI during EN. The most common FI symptom was diarrhea (41.58%), followed by gastric retention, reflux, abdominal distension, nausea, abdominal pain, vomiting, and aspiration, with blood in stool being the least common (3.37%). Compared to the EN tolerance group, the EN intolerance group had significantly higher proportions of patients aged ≥60 years, undergoing mechanical ventilation, receiving analgesic and sedative medications, having hyperglycemia, using short-peptide EN fluids, receiving continuous EN, and having a feeding rate > 40 mL/h (all P < 0.05). The binary multivariate Logistic regression analysis revealed that age ≥60 years [odds ratio (OR) = 1.738, 95% confidence interval (95%CI) was 1.241-2.436, P = 0.001], continuous EN (OR = 0.534, 95%CI was 0.377-0.756, P < 0.001), use of analgesic medications (OR = 1.701, 95%CI was 1.139-2.539, P = 0.009), hyperglycemic state (OR = 2.794, 95%CI was 1.999-3.907, P < 0.001), and tube feeding rate > 40 mL/h (OR = 1.018, 95%CI was 1.009-1.027, P < 0.001) were independent risk factors for FI during EN in ICU patients. CONCLUSIONS The incidence of FI during EN in ICU patients is relatively high and influenced by age, EN methods, analgesic medications, hyperglycemic state, and tube feeding rate. Therefore, healthcare professionals need to accurately identify the risk factors for FI and actively implement effective intervention measures to reduce the incidence of FI and improve patient outcomes.

OBJECTIVE: To systematically review safety and tolerance of enteral nutrition (EN) in a prone position, as well as the risks of increased gastric residual volume (GRV), vomiting, aspiration, and ventilator-associated pneumonia, and determine the ways to improve EN tolerance in patients with acute respiratory distress syndrome (ARDS). METHODS: Databases including PubMed, Embase and Wanfang Medical data of the English and Chinese literatures were retrieved up from January 1979 to January 2022 to collet the randomized controlled trial (RCT), non-RCT, and observational studies, concerning safety and tolerance of EN in a prone position with ARDS. All trials must have a minimum of two patient groups, one of which must be prone to ARDS and receive EN. Data searching extracting and quality evaluation were assessed by two reviewers independently. RevMan 5.4 software was used for analysis. RESULTS: A total of 9 studies were included, including 2 RCTs, 2 non-RCTs, 4 prospective observational studies, and 1 retrospective observational study. The starting and increasing rate of EN were typically well tolerated in the prone position compared to the supine position in patients with ARDS, there was no significant increase in GRV (mL: 95 vs. 110), and the incidence of vomiting was not noticeably higher (0%-35% vs. 33%-57%). The incidence of ventilator-associated pneumonia with EN was not significantly higher in the prone position than in the supine position in patients with ARDS (6%-35% vs. 15%-24%). Aspiration occurred at a similar rate in patients in the nasogastric tube and post-pyloric feeding groups with EN in patients with ARDS in the prone position (22% vs. 20%). EN tolerability with nasogastric and nasojejunal tubes was similar in prone positions, with no significant difference in EN intolerance incidences (15% vs. 22%). Head elevation (30 degree angle-45 degree angle) improved EN tolerance in the prone position in patients with ARDS, thereby increasing the early EN dose [odds ratio (OR) = 0.48, 95% confidence interval (95%CI) was 0.22-1.08, P = 0.08]. Additionally, prophylactic application of gastrointestinal motility drugs, such as erythromycin, at the start of EN in a prone position significantly improved patients' EN tolerance (OR = 1.14, 95%CI was 0.63-2.05, P = 0.67). CONCLUSIONS The use of gastric tube for EN in prone position and similar feeding speed to the supine position in patients with ARDS is safe and well tolerated. The initiation and dosing of EN should not be delayed in the prone position. EN tolerance may be increased by elevating the head of the bed during enteral feeding in a prone position, and gastrointestinal motility medications should be promptly administered with EN initiation in patients with ARDS.

BACKGROUND: Feeding intolerance (FI) among intensive care unit (ICU) patients undergoing early continuous enteral nutrition (EN) is related to poor outcomes. This study aimed to explore the prevalence and risk factors of FI in ICU patients. METHODS: We retrospectively enrolled 1057 patients who received early continuous EN via a nasogastric tube between January 2014 and August 2019. The prevalence of FI during the first 7 days of ICU stay was calculated, and the risk factors were investigated using multivariate logistic regression analysis. RESULTS: The prevalence of FI during the first 7 days of ICU stay was 10.95%. FI occurred in 159 of 1057 (15.04%) patients on ICU day 2, 114 of 977 (11.67%) patients on ICU day 3, and 86 of 715 (12.03%) patients on ICU day 7. Mechanical ventilation (MV) (odds ratio [OR]: 1.928, 95% confidence interval [CI]: 1.064-3.493, P  = 0.03) was an independent risk factor for FI defined by a gastric residual volume (GRV) of 200 mL and/or vomiting, and acute renal failure (OR: 3.445, 95% CI: 1.115-10.707, P  = 0.032) was an independent risk factor of FI defined by a GRV of 500 mL and/or vomiting. Continuous renal replacement therapy (CRRT) was an independent predictor regardless of the FI defined by a GRV of 200 mL (OR: 2.064, 95% CI: 1.233-3.456, P  = 0.006) or 500 mL (OR: 6.199, 95% CI: 2.108-18.228, P  = 0.001) in the ICU patients. CONCLUSIONS FI occurs frequently in early ICU days, especially in patients receiving MV and CRRT. However, further investigation of a consensus definition of FI and risk factors is still warranted in future studies.

As a serious disease of death and disability, stroke constitutes a serious threat to human health. Because of stroke patients often have high-risk factors of malnutrition such as dysphagia and autonomic eating disorder, the hospitalization time, mortality and disability rate of stroke patients increases. Nutritional therapy can effectively improve the malnutrition of patients, which are of great significance for the treatment and rehabilitation of stroke and the prevention of its complications. Nutrients are important components of nutrition therapy, and different ways of nutrition therapy directly affect the effect of treatment. This article summarizes effects of nutrients and different nutritional treatments on stroke prevention, morbidity and treatment, and provides a theoretical basis and new thinking for further reducing the incidence rate of stroke, improving the quality of life in patients and reducing the financial burden of society and family.

Intestinal failure (IF) is defined as the critical reduction of functional intestines below the minimum needed to absorb nutrients and fluids, so that intravenous supplementation with parenteral nutrition (PN) is required to maintain health and/or growth. Although the benefits are evident, patients receiving PN can suffer from serious cholestasis due to lack of enteral feeding and small intestinal bacterial overgrowth (SIBO). One such complication that may arise is intestinal failure-associated liver disease (IFALD). Evidences from recent studies suggest that alterations in the intestinal microbiota, as well as intraluminal bile acid driven signaling, may play a critical role in both hepatic and intestinal injury. Since Marshall first proposed the concept of the gut-liver axis in 1998, the role of gut-liver axis disorders in the development of IFALD has received considerable attention. The conversation between gut and liver is the key to maintain liver metabolism and intestinal homeostasis, which influences each other and is reciprocal causation. However, as a "forgotten organ" , intestinal microbiota on the pathogenesis of IFALD has not been well reflected. As such, we propose, for the first time, the concept of gut-microbiota-liver axis to emphasize the importance of intestinal microbiota in the interaction of gut-liver axis. Analysis and research on gut-microbiota-liver axis will be of great significance for understanding the pathogenesis of IFALD and improving the prevention and treatment measures.

OBJECTIVETo compared the clinical efficacy of laparoscopic repair (LR) versus open repair (OR) for perforated peptic ulcers.

METHODSFrom January 2010 to June 2014, in Shanghai Tongji Hospital, 119 patients who were diagnosed as perforated peptic ulcers and planned to receive operation were prospectively enrolled. Patients were randomly divided into LR (58 patients) and OR(61 patients) group by computer. Intra-operative and postoperative parameters were compared between two groups. This study was registered as a randomized controlled trial by the China Clinical Trials Registry (registration No.ChiCTR-TRC-11001607).

RESULTSThere was no significant difference in baseline data between two groups (all P>0.05). No significant differences of operation time, morbidity of postoperative complication, mortality, reoperation probability, decompression time, fluid diet recovery time and hospitalization cost were found between two groups (all P>0.05). As compared to OR group, LR group required less postoperative fentanyl [(0.74±0.33) mg vs. (1.04±0.39) mg, t=-4.519, P=0.000] and had shorter hospital stay [median 7(5 to 9) days vs. 8(7 to 10) days, U=-2.090, P=0.001]. In LR group, 3 patients(5.2%) had leakage in perforation site after surgery. One case received laparotomy on the second day after surgery for diffuse peritonitis. The other two received conservative treatment (total parenteral nutrition and enteral nutrition). There was no recurrence of perforation in OR group. One patient of each group died of multiple organ dysfunction syndrome (MODS) 22 days after surgery.

CONCLUSIONLR may be preferable for treating perforated peptic ulcers than OR, however preventive measures during LR should be taken to avoid postopertive leak in perforation site.

Duodenal injury is a serious abdominal organ injury. Duodenal fistula is one of the most serious complications in gastrointestinal surgery, which is concerned for its critical status, difficulty in treatment and high mortality. Thoracic and abdominal compound closed injury and a small part of open injury are common causes of duodenal injury. Iatrogenic or traumatic injury, malnutrition, cancer, tuberculosis, Crohn's disease etc. are common causes of duodenal fistula, however, there has been still lacking of ideal diagnosis and treatment by now. The primary treatment strategy of duodenal fistula is to determine the cause of disease and its key point is prevention, including perioperative parenteral and enteral nutrition support, improvement of hypoproteinemia actively, avoidance of stump ischemia by excessive separate duodenum intraoperatively, performance of appropriate duodenum stump suture to ensure the stump blood supply, and avoidance of postoperative input loop obstruction, postoperative stump bleeding or hematoma etc. Once duodenal fistula occurs, a simple and reasonable operation can be selected and performed after fluid prohibition, parenteral and enteral nutrition, acid suppression, enzyme inhibition, anti-infective treatment and maintaining water salt electrolyte and acid-base balance. Double tube method, duodenal decompression and peritoneal drainage can reduce duodenal fistula-related complications, and then reduce the mortality, which can save the lives of patients.

Intestinal fistula, as a serious complication after abdominal surgery, not only leads to a series of pathophysiological changes such as fluid loss, malnutrition and organ dysfunction, but also causes the severe abdominal infection, which often threatens the life of patients. How to make the diagnosis and give the treatment of intestinal fistula is the key to save the lives of high-risk patients. In our hospital, during the past course of diagnosis and treatment for intestinal fistula complicated with severe abdominal infection, based on the combination of literatures at home and abroad with our clinical experiences for many years, an effective three-stage prevention and treatment strategy was formed gradually, which included early diagnosis, effective treatment of infection source, open drainage of abdominal infection and early enteral nutrition support. This strategy subverts the traditional concept of surgery alone, and becomes an effective means to save patients with severe abdominal infection.
