The Subjective Global Assessment(SGA) is widely applied in the clinic.The usage and the clinical purpose of SGA is quite different among the various studies.In some studies,SGA proved to be a good screening tool for nutritional risk or a prognostic indicator for poorer outcomes.In several clinical setting,SGA was employed as a "gold standard" method against which new nutritional assessment methods were validated.At present,the different indicators of nutritional assessment reflect the different characteristics of the body's nutritional status changes.The different indicators and methods should be incorporated according to the patient in order to objectively and correctly assess the patient's nutritional status.

Glutamine is the most abundant free amino acid in the body,which is regarded as a conditionally essential amino acid under the conditions of stress and hypermetabolism.It has been proved that glutamine can enhance the proliferation of immune cells and the repair of impaired mucosa and can also improve the nitrogen balance and skeletal muscle protein synthesis.Therefore,it is now more and more widely used in the bone marrow transplantation.The roles of glutamine in the prevention and treatment of bone marrow transplantation-related mucositis and veno-occlusive disease are reviewed in this article.

Objective To establish a comprehensive nutritional assessment scale for hospitalized patients with objective and subjective nutritional assessment indicators. Methods The hierarchical structure model was established to evaluate the nutritional status of hospitalized patients by analytic hierarchy process,and the weight coefficients of various assessment indicators were worked out by Satty product method,then the comprehensive nutritional assessment scale for hospitalized patients was established. ResuIts The newly established comprehensive nutritional assessment scale included 11 subjective and objective indicators,and the weight coefficients of indicators varied.The leading three important indicators for nutritional assessment were serum prealbumin(2.3),serum albumin(2.3)and degree of weight loss(1.6).Conclusion With both snbjective and objective indicators,the new comprehensive nutritional assessment scale established with analytic hierarchy process transforms the qualitative indicator into the quantitative one.It is a new attempt to apply the mathematical theory into the area of clinical medicine.

PURPOSE: This study was aimed at identifying the influence of initial weight and weight change during neoadjuvant chemotherapy (NAC) on pathologic complete response (pCR) and long-term survival in Chinese patients with operable breast cancer. METHODS: We conducted a retrospective study using data from 409 female patients who received NAC for stage II or III breast cancer and had complete record of body mass index (BMI) before and after NAC. BMI of < 25 kg/m² was categorized as normal weight/underweight (NW/UW); 25.0–29.9 kg/m² was categorized as overweight (OW); ≥30 kg/m² was categorized as obese (OB). BMI change was defined as the difference in BMI between day 1 of the first cycle of NAC and the day before surgery. A BMI gain or loss of > 2 kg/m² following NAC was considered to be significant, else was considered stable. The study end points included pCR rates, disease-free survival (DFS), and overall survival (OS). RESULTS: The median follow-up time was 43.2 (8.9–93.6) months. The average BMI was 23.40 ± 3.04 kg/m² before NAC and 23.66 ± 3.02 kg/m² after NAC (t = −3.604, p < 0.001). The pCR rate was 25.3% in the NW/UW group and 24.1% in the OW/OB group (p = 0.811), and was similar between the BMI-gain (23.3%) and the BMI-stable/loss (25.1%) groups (p = 0.787). Initial BMI was an independent prognostic factor for DFS (hazard ratio, 1.69; 95% confidence interval [CI], 1.13–2.53; p = 0.011) but not for OS, while BMI-gain was an independent prognostic factor for both DFS (hazard ratio, 2.09; 95% CI, 1.28–3.42; p = 0.003) and OS (hazard ratio, 1.97; 95% CI, 1.04–3.74; p = 0.039). CONCLUSION: BMI increased after NAC in Chinese breast cancer patients. Initial BMI and BMI change during NAC were not associated with pCR but were reversely associated with survival.

Objective:To establish an early prediction model for bloodstream infection in patients with extremely severe burns based on the screened independent risk factors of the infection, and to analyze its predictive value.Methods:A retrospective case-control study was conducted. From January 1, 2010 to December 31, 2019, 307 patients with extremely severe burns were admitted to the Department of Burns and Plastic Surgery of Ruijin Hospital Affiliated to Shanghai Jiao Tong University School of Medcine, including 251 males and 56 females, aged from 33 to 55 years. According to the occurrence of bloodstream infection, the patients were divided into non-bloodstream infection group (221 cases) and bloodstream infection group (86 cases). The gender, age, body mass index, outcome, length of hospital stay of patients were compared between the two groups, and the detection of bacteria in blood microbial culture of patients was analyzed in bloodstream infection group. The included 307 patients were divided into modeling group (219 cases) and validation group (88 cases) according to the random number table with a ratio of about 7∶3. The gender, age, body mass index, total burn area, full-thickness burn area, combination of inhalation injury, implementation of mechanical ventilation, days of mechanical ventilation, days of intensive care unit (ICU) stay, outcome, length of hospital stay, complication of bloodstream infection of patients were compared between the two groups. According to the occurrence of bloodstream infection, the patients in modeling group were divided into bloodstream infection subgroup (154 cases) and non-bloodstream infection subgroup (165 cases). The total burn area, full-thickness burn area, combination of inhalation injury, implementation of mechanical ventilation, days of mechanical ventilation, and days of ICU stay of patients were compared between the two subgroups. The above-mentioned data between two groups were statistically analyzed with one-way analysis of independent sample t test, chi-square test, and Mann-Whitney U test to screen out the factors with statistically significant differences in the subgroup univariate analysis of modeling group. The factors were used as variables, and binary multivariate logistic regression analysis was performed to screen out the independent risk factors of bloodstream infection in patients with extremely severe burns, based on which the prediction model for bloodstream infection in patients with extremely severe burns of modeling group was established. The receiver operating characteristic (ROC) curve of the prediction model predicting the risk of bloodstream infection of patients in modeling group was drawn, and the area under the ROC curve was calculated. The sensitivity, specificity, and the best prediction probability were calculated according to the Youden index. According to the occurrence of bloodstream infection, the patients in validation group were divided into bloodstream infection subgroup (21 cases) and non-bloodstream infection subgroup (67 cases). The prediction probability >the best prediction probability of model was used as the judgment standard of bloodstream infection. The prediction model was used to predict the occurrence of bloodstream infection of patients in the two subgroups of validation group, and the incidence, specificity, and sensitivity for predicting bloodstream infection were calculated. In addition, the ROC curve of the prediction model predicting the risk of bloodstream infection of patients in validation group was drawn, and the area under the ROC curve was calculated. Results:Compared with those of non-bloodstream infection group, the mortality of patients in bloodstream infection group was significantly higher ( χ2=8.485, P<0.01), the length of hospital stay was significantly increased ( Z=-3.003, P<0.01), but there was no significant change in gender, age, or body mass index ( P>0.05). In patients of bloodstream infection group, 110 strains of bacteria were detected in blood microbial culture, among which Klebsiella pneumoniae, Pseudomonas aeruginosa, and Acinetobacter baumannii were the top three bacteria, accounting for 35.45% (39/110), 26.36% (29/110), and 13.64% (15/110), respectively. Gender, age, body mass index, total burn area, full-thickness burn area, proportion of combination of inhalation injury, proportion of implementation of mechanical ventilation, days of mechanical ventilation, days of ICU stay, outcome, length of hospital stay, and proportion of complication of bloodstream infection of patients were similar between modeling group and validation group ( P>0.05). Compared with those of non-bloodstream infection subgroup in modeling group, the total burn area, full-thickness burn area, proportion of combination of inhalation injury, proportion of implementation of mechanical ventilation, days of mechanical ventilation, and days of ICU stay of patients in bloodstream infection subgroup were significantly increased ( Z=-4.429, t=-4.045, χ2=7.845, 8.845, Z=-3.904, -4.134, P<0.01). Binary multivariate logistic regression analysis showed that total burn area, days of ICU stay, and combination of inhalation injury were the independent risk factors for bloodstream infection of patients in modeling group (odds ratio=1.031, 1.018, 2.871, 95% confidence interval=1.004-1.059, 1.006-1.030, 1.345-6.128, P<0.05 or P<0.01). In modeling group, the area under the ROC curve was 0.773 (95% confidence interval=0.708-0.838); the sensitivity was 64.6%, the specificity was 77.9%, and the best prediction probability was 0.335 when the Youden index was 0.425. The bloodstream infection incidence of patients predicted by the prediction model in validation group was 27.27% (24/88), with specificity of 82.09% (55/67) and sensitivity of 57.14% (12/21). The area under the ROC curve in validation group was 0.759 (95% confidence interval=0.637-0.882). Conclusions:The total burn area, days of ICU stay, and combination of inhalation injury are the risk factors of bloodstream infection in patients with extremely severe burns. The early prediction model for bloodstream infection risk in patients with extremely severe burns based on these factors has certain predictive value for burn centers with relatively stable treatment methods and bacterial epidemiology.

Objective To analyze the main factors affecting early using enteral nutrition and the effect of enteral nutrition within 72 h after burning on outcomes by presenting a retrospective cohort study of 11 years of hospitalization data,to provide evidence for enteral nutrition regimens for severe burn patients.Methods A retrospective study analyzed adult extensive burn patients between January 2009 and December 2020.Patients enrolled in this study who admitted to the burn department within 24 h after burning and with a burned area of more than 30%.Univariate and multiple regression were used to analyze the main factors affecting early using enteral nutrition in patients with severe burn.Non parametric Mann-Whitney U test was used to compare the main influencing factors of enteral nutrition implementation within or after 72 h,as well as the impact on the treatment outcomes such as 28-day survival rate and in hospital survival rate.Results The univariate analysis found that total burn area,full-thickness burn area,burn type,and inhalation injury were the main factors of the time to initation of enteral nutrition in patients with severe burn(P<0.05).Incorporating the above single factors into multiple regression analysis,we found that the main factors affecting enteral nutrition using in patients with severe burn were full-thickness burn area(P=0.017)and inhalation injury(P=0.001).To analysis whether enteral nutrition was started within 72 h after burning,we found that inhalation injury and larger area of full-thickness burn area in patients was the main factors for initiating enteral nutrition.After matching injury situation with pre-injury situation,we found that using enteral nutrition within or after 72 h after injury were no significant differences in the survival rate,28-day survival rate,and positive blood culture rate(P>0.05),but was associated with the lower incidence of bacteria positive in intravenous catheters(P=0.001)and the lower rate of parenteral nutrition treatment used within 7 d after burning(P= 0.001).Conclusions The main factor for influencing early implement enteral nutrition in patients with severe burn were large area of full-thickness burn and inhalation injury.Enteral nutrition using within 72 h after burning reduces the incidence of catheter infection and the use of parenteral nutrition,thereby reducing the risk of treatment in patients with severe burn.
