Nutritional status and its association with in-hospital major adverse cardiac events in patients with severe heart failure: a prospective study / Estado nutricional y su asociación con eventos cardíacos adversos mayores intrahospitalarios en pacientes con insuficiencia cardíaca grave: un estudio prospectivo

Objectives: this study aimed to evaluate the relationship of Nutritional Risk Screening 2002 (NRS2002) and in-hospital major adverse cardiac events (MACE) in patients with severe heart failure. Methods: an observational study was conducted at the emergency intensive care units (EICU) of Shandong University Qilu Hospital from January 2017 to December 2019. Nutritional screening and assessment were performed at the time of admission to hospital with the NRS2002. Results: of the 209 patients included, 16 cases (7.66 %) were not at nutritional risk, and 193 cases (92.34 %) were at risk. Among them, 12 cases (5.74 %) were malnourished, 38 cases (18.18 %) were at high nutritional risk, and 115 cases (55.02 %) were overweight and obese. The differences in prealbumin (PA) and N-terminal B-type natriuretic peptide precursor (NT-proBNP) between the 2 groups were statistically signific ant (p < 0.05). A total of 134 cases (64.12 %) received nutrition treatment support, of which 39 cases (29.10 %) received enteral nutrition (EN), 77 cases (57.46 %) parenteral nutrition, and 18 cases (13.43 %) enteral nutrition combined with parenteral nutrition (EN + SPN) support treatment. In all, 31 cases (54.39 %) reached 100 % of the target dose. Patients in the EN and EN + SPN groups had 37 MACE (64.91 %) and 31 enteral nutrition complications (54.39 %), with differences between the 3 groups being statistically significant (p < 0.05). Conclusion: the nutritional risk of patients with severe heart failure is high, and age and heart function are positively correlated with nutritional risk. The complications rate of patients with high nutritional risk is significantly higher than in those with low risk; the higher the nutritional risk, the higher the hospital mortality rate — that is, nutritional risk affects disease outcome (AU)

Objetivos: este estudio tuvo como objetivo evaluar la relación del Nutritional Risk Screening 2002 (NRS2002) con los eventos cardiacos adversos mayores intrahospitalarios (MACE) en pacientes con insuficiencia cardiaca grave. Métodos: se realizó un estudio observacional en las unidades de cuidados intensivos de emergencia (UCIE) del Hospital Qilu de la Universidad de Shandong desde enero de 2017 a diciembre de 2019. Se realizaron un cribado y una evaluación nutricional en el momento del ingreso hospitalario con el NRS2002. Resultados: de los 209 pacientes incluidos, 16 casos (7,66 %) no tenían riesgo nutricional y 193 casos (92,34 %) sí lo tenían. Entre ellos, 12 casos (5,74 %) estaban desnutridos, 38 casos (18,18 %) tenían un alto riesgo nutricional y 115 casos (55,02 %) tenían sobrepeso u obesidad. Las diferencias de prealbúmina (PA) y precursor del péptido natriurético de tipo B N-terminal (NT-proBNP) entre los 2 grupos fueron estadísticamente significativas (p < 0,05). En total, 134 casos (64,12 %) recibieron soporte de tratamiento nutricional, de los que 39 casos (29,10 %) recibieron nutrición enteral (NE), 77 casos (57,46 %) nutrición parenteral y 18 casos (13,43 %) nutrición enteral combinada con nutrición parenteral (NE + SPN) como tratamiento de apoyo. Treinta y un casos (54,39 %) alcanzaron la dosis objetivo al 100 %. Los pacientes de los grupos EN y EN + SPN tuvieron 37 MACE (64,91 %) y 31 complicaciones de la nutrición enteral (54,39 %), siendo la diferencia entre los 3 grupos estadísticamente significativa (p < 0,05). Conclusiones: el riesgo nutricional de los pacientes con insuficiencia cardíaca grave es alto; la edad y la función cardiaca se correlacionan positivamente con el riesgo nutricional. La complicación de los pacientes con alto riesgo nutricional es significativamente mayor que la de los de bajo riesgo; cuanto mayor es el riesgo nutricional (AU)

Gross tumor volume delineation with combination of non-contrast/contrast CT and FDG PET in pancreatic cancer / 中华放射肿瘤学杂志

ObjectiveTo investigate the application of non-contrast and contrast-enhanced 18FDG PET/CT in the delineation of gross tumor volume ( GTV ) of pancreatic cancer.MethodsBetween Jan.2008 and Dec.2009,twenty-one patients with unresectable locally advanced pancreatic cancer or recurrent pancreatic cancer after surgery in our hospital had both non-contrast CT and PET images acquired at the same body position.Among the whole group,eleven patients also had contrast CT images.The image data sets were transferred to the treatment planning workstation for registration.Then gross tumor volumes ( GTV )were delineated independently using the information of PET images,contrast/non-contrast CT scan and contrast/non-contrast PET-CT fusion images.The differences of mean volume in these different sets of GTV were analyzed.Results For the whole group,the mean volume of non-contrast GTVCT,GTVPET,noncontrast GTVPET-CT were 76.9 cm3,47.0 cm3 and 44.5 cm3,respectively.The mean volume of non-contrast GTVPET-CT was significantly smaller than non-contrast GTVCT ( z =-3.91,P =0.000 ).For the eleven patients with contrast CT,the mean volume of contrast GTVCT,GTVPET,contrast GTVPET-CT were 64.1 cm3,45.1 cm3 and 49.3 cm3,respectively.The mean volume of contrast GTVPET-CT was significantly smaller than contrast GTVCT (z =-2.13,P =0.033 ).No significant differences were found between contrast PET-CT and non-contrast PET-CT (z =-0.80,P =0.424).ConclusionsCo-registration of PET and contrast/noncontrast CT information in pancreatic cancer may improve the accuracy of GTV delineation,and possibly reduce the adverse effect of irradiation.

Risk factors for brain metastasis in small-cell lung cancer after surgery / 中华放射肿瘤学杂志

Objective To evaluate clinical risk factors that can predict brain metastasis after complete resection of small cell lung cancer (SCLC) and to assess the role of prophylactic cranial irradiation (PCI) in such kind of patients.Methods Eighty-eight patients with completely resected stage Ⅰ - Ⅲ SCLC from Jan.2000 to Dec.2009 in our hospital were retrospectively analyzed.Kaplan-Meier was used to compare the differences in the incidence of metastasis free survival in different groups.Logistic model was used to assess the independent risk factors for brain metastasis.Results The follow-up rate is 100％,and 37 patients were followed up for more than three years.None of the 3 patients who received PCI developed brain metastasis,while for patients without receiving PCI,24％ developed brain metastases.The incidence of brain metastasis for stage Ⅰ,Ⅱ and Ⅲ SCLC after surgery were 4％,26％ and 29％ ( x2 =7.57,P =0.023),respectively.The median survival time and the 3-year survival rate were 18 months and 25％ for patients who developed brain metastasis,and 48 months and 59％ for those without brain metastasis ( x2 =10.63,P =0.001 ).Both univariate and multivariate analyses showed that pre-treatment disease stage wasindependent risk factor for brain metastasis ( x2 =7.57,8.52 ; P =0.023,0.004 ).Age,sex,tumor location,pathological type,induction chemotherapy,and postoperative chemotherapy/radiotherapy were not significantly correlated with the incidence of brain metastasis ( x2 =0.03,0.00,0.00,2.58,0.01,1.23,0.84;P =0.869,0.998,0.992,0.109,0.936,0.266,0.361,respectively).Conclusions Pre-treatment disease stage was independent risk factor for brain metastasis in SCLC.PCI may be important for stage Ⅱ -Ⅲ SCLC but not for stage Ⅰ disease.=Carcinoma,small cell lung/surgery; Neoplasm metastasis,brain/prophylactic irradiation; Factors analysis

The significance of the characteristics of intra-thoracic lymph node metastasis for radiotherapy range in small cell lung cancer / 中华放射肿瘤学杂志

Objective To explore the reasonable radiotherapy range by analyzing the patterns and characteristics of intra-thoracic lymph node metastasis in small cell lung cancer (SCLC).Methods One hundred and fifty patients with limited-stage SCLC who received radical resection of primary tumor and systemic intra-thoracic lymph node dissection were included in the study.All the lymph nodes in each area were recorded and examined pathologically to analyze the patterns and characteristics of intra-thoracic lymph node metastasis.Results A total of 2372 lymph nodes were found in 631 areas,and a total of 413 positive lymph nodes (17.4％) were found in 188 lymph node areas (29.8％ ).Intra-thoracic lymph node metastasis were found in 88 patients,with a positive rate of 58.7％.The frequencies of metastasis in the area 11,10,7,5,4 were much higher than those in the other areas,and central located lesions and the higher T-stage lung tumors were more likely to develop intra-thoracic lymph node metastasis (x2 =15.32,39.72;P =0.000,0.000,respectively).Tumors located in the right upper lobe and right middle/lower lobe had a higher tendency of metastasis to the areas 4,7,10 and 4,7,10,11,respectively.Tumors located in the left upper lobe and left lower lobe had a higher tendency of metastasis to the areas 4,5,6,10 and 4,7,9,10,11,respectively.Mediastinal lymph node metastasis (N2 ) were found in 72 patients,among whom 29 patients (40.3％ ) had skipping N2 metastasis without hilar metastasis.Tumors located in the upper lobe had a tendency of skipping metastasis to the upper mediastinum,while tumors located in the middle/lower lobe had a tendency of skipping metastasis to the upper and lower mediastinum.Conclusions The lymph node metastases in SCLC follow the lymphatic drainage routes,that is,from intrapulmonary to the hilar and then to the mediastinum,but with some skipping metastases.Tumors located in different lobes have different high risk lymph node areas for metastasis,and elective irradiation to these lymph node areas maybe increase radiotherapy gain ratio in SCLC.
