RESUMO
BACKGROUND: The primary aim of the study was to assess the nutritional status of pediatric liver transplant outpatients in nutrition clinic, particularly the nutritional status of their bones. METHODS: One hundred thirty-eight pediatric liver transplant outpatients, who had visited the nutrition clinic in Shanghai Children's Medical Center between January 2017 and December 2019, were recruited. The bone mineral density (BMD) z-scores were determined by dual energy X-ray absorptiometry (DXA). Nutritional assessment was performed, and their corresponding height-for-age z-scores (HAZs)/weight-for-age z-scores (WAZs)/BMI-for-age z-scores (BMIZs) were obtained. RESULTS: A total of 138 patients came to our nutrition outpatient clinic, including 68 boys (49.3%) and 70 girls (50.7%). The median age was 0.87y (0.68y, 1.71y). Among these patients, 44 (31.9%) had acute malnutrition with WAZ/BMIZ value -1.14 (-2.38, -0.18), 55 (38.4%) had chronic malnutrition with HAZ value -1.51 (-2.39, -0.38), and 96 (69.6%) had a BMD lower than normal. The BMD z-score was significantly correlated with the WAZ/BMIZ value (Spearman's correlation coefficient = 0.334, p < 0.001). A total of 37 infants re-visited the nutrition clinic for a follow-up after (147 ± 127) days. The WAZ/BMIZ value of the re-visiting patients and the BMD z-score of the re-visiting patients were significantly improved compared to those of the first-visit patients (p = 0.004 and p = 0.001 respectively). CONCLUSIONS: There were different rates of malnutrition before and after liver transplantation. At the same time, BMD Z-score and serum vitamin D level of patients decreased. There was a significant correlation between BMD z-scores and WAZ/BMIZ values. Proper and professional nutrition guidance significantly improved the WAZ/BMIZ-values and BMD Z-score of liver transplantation patients.

AIM: To investigate paediatric outpatients' nutritional status using bioelectrical impedance analysis and anthropometric z-scores. METHODS: A retrospective data analysis of tertiary paediatric hospital outpatients from 2017 to 2019 was conducted. Patients were categorised into three groups (non-illness, illness and simple obesity) according to clinical diagnoses. The nutritional status was evaluated using anthropometric and bioelectrical impedance analysis. In addition, body composition measurements of patients in three subgroups of the illness group and age- and gender-matched healthy controls were compared. RESULTS: A total of 2015 paediatric outpatients were enrolled. According to body mass index z-scores, undernutrition prevalence among participants was 14.0% (non-illness group, 21.3%; illness group, 11.4%). Body composition measurements indicated that 41.6% of participants had a low fat-free mass index, and the proportions of participants with a low fat-free mass index in the non-illness, illness and simple obesity groups were 48.4, 47.0 and 10.7%, respectively. Compared with healthy controls, the haematology and oncology subgroup had a significantly lower fat-free mass index and fat mass index; the nephrology and rheumatology subgroup had significantly lower height-for-age z-scores but higher fat mass index; and the gastroenterology subgroups had lower fat mass index, fat-free mass index and body mass index z-scores. CONCLUSIONS: The results suggested the low fat-free mass index prevalence was greater than the low body mass index z-score prevalence among paediatric outpatients, and body composition parameters varied across different illnesses. Body composition analysis is recommended in nutrition clinics for accurate paediatric outpatient nutritional assessment, thereby providing timely individualised nutritional interventions.

BACKGROUND: Myocardial ischemia-reperfusion injury (MIRI) is defined as the restoration of blood flow to the myocardium after a brief interruption of blood supply, causing more severe damage to the ischemic myocardium. However, currently, reperfusion therapy is the preferred therapy for ischemic cardiomyopathy, which undoubtedly causes MIRI, and thus it has become a challenging issue affecting the prognosis of coronary artery disease. METHODS: A search was conducted in the Web of Science Core Collection database for papers relevant to MIRI therapy published between 1 January 2000 and 1 October 2023. Bibliometric analyses were performed using VOSviewer and CiteSpace to elucidate the progress and hotspots. RESULTS: 3304 papers from 64 countries, 2134 research institutions and 13,228 authors were enrolled in the study. Of these, China contributed the most papers and had the biggest impact, while the United States had the most extensive partnership. The Fourth Military Medical University was the primary research institution. The most valuable authors include Chattipakorn, Nipon, Chattipakorn, Siriporn c, Yang, Jian and Yang, Yang. CONCLUSION: Over the past 20 years, research on MIRI therapies has made significant strides. Further studies are necessary to explore the interactions between various therapeutic options. Future investigations will emphasize nanocarriers, cardiac regeneration, and stem cell therapies. Our study identifies MIRI research hotspots from a bibliometric perspective, forecasts future trends, and offers fresh insights into MIRI therapy research.

OBJECTIVES: This study aimed to evaluate the nutrition risk profile of hospitalized children with electronic health record-based nutrition risk screening. Additionally, this study analyzed the association between high nutrition risk and clinical outcomes. METHODS: Children discharged from Shanghai Children's Medical Center between 2017 and 2018 were enrolled and nutritionally screened. Nutrition risk scores using the Screening Tool for Assessment of Malnutrition in Pediatrics (STAMP), length of stay (LOS), and costs of hospitalization were recorded. Enrolled patients were categorized into two groups: the low and medium nutrition risk (LMNR) group, with scores ranging from 0 to 3, and the high nutrition risk (HNR) group, with scores ≥4. RESULTS: Out of 62 408 subjects, 17.4% were at HNR. Patients with congenital heart diseases (83.9%), hematology-oncology diseases (26.0%) and gastroenterological diseases (21.4%) were affected most. Infants had the highest HNR rates (35.5%) of any age group. Surgical patients (20.7%) had a higher rate of HNR than non-surgical patients (9.5%). The HNR group had longer LOS (10.0 d versus 3.0 d, P < 0.001), higher total hospital costs (53 680.1 Chinese yuan [CNY] versus 8810.1 CNY, P < 0.001), and higher costs of antibiotics (441.0 CNY versus 0.0 CNY, P < 0.001) compared to the LMNR group. As STAMP score values increased, growing LOS and costs of hospitalization, medications, and antibiotics were observed. CONCLUSIONS: A high prevalence of HNR was found in patients of Shanghai Children's Medical Center. Surgeries, specific disease, and infancy were important HNR risk factors. HNR scores using STAMP might predict prolonged LOS and higher medical costs.

This study investigated the rapid start-up of the anaerobic ammonium oxidation (anammox) strategy by inoculating different biomass ratios of denitrifying granular sludge and anammox bacteria. The results demonstrated that two reactors (R1 and R2) were rapidly and successfully started-up on days 25 and 28, respectively, with nitrogen removal rates (NRRs) of 0.70kg/(m(3)·d) and 0.72kg/(m(3)·d) at biomass ratios of 10:1 (R1) and 50:1 (R2). The explanation for rapid start-up was found by examining the effect of five different sludge extracellular polymeric substances (EPS) on the activity of anammox bacteria in the batch experiments. Batch experiments results first demonstrated that the denitrification sludge EPS (DS-EPS) enhanced the anammox bacteria activity the most, and NO2(-)-N, NH4(+)-N removal rates were 1.88- and 1.53-fold higher than the control with optimal DS-EPS volume of 10mL. The rapid start-up strategy makes possible the application of anammox to practical engineering.
