Objective To investigate the nursing care burden,medical assurance and comorbidities of patients with hereditary epidermolysis bullosa (EB) in China.Methods From September to December in 2018,a cross-sectional telephone/internet-based questionnaire survey was conducted in EB patients registered at DebRA China between January 2013 and September 2018.Results Totally,377 participants (EB patients or their parents) were enrolled into this survey,and a total of 367 valid questionnaires were collected.Of the 367 registered patients with EB,275 (74.9％) were minors,and 319 (92％) reported wound care costs per month less than 3 000 RMB Yuan,and 211 (57.5％) reported that medical expenses were mainly paid by themselves.These patients were distributed in 30 provinces,autonomous regions or municipalities directly under the central government of China,and no patient was from Tibet.The largest number of registered patients was from Jiangsu province (49/367),followed by Henan (35/367),Guangdong (27/367),Hebei (23/367) and Shandong (20/367) provinces.Of the 367 patients,168 received genetic testing.The most common comorbidities of EB patients were nail peeling and itching,with the prevalence rate being 66.2％ and 55.3％ respectively.Disabilities occurred in 122 (33.2％) patients,102 (27.8％) of which had physical disabilities.Conclusion Most of EB patients cannot obtain appropriate diagnosis,nursing care and medical assurance,comorbidities and disabilities are common,and their quality of life is very low.

Objective:To explore the clinical value of N terminal pro B type natriuretic peptide (NT-proBNP) in diagnosing or predicting heart failure in peridialysis chronic kidney disease (CKD) population.Methods:It was a single-center retrospective study. Patients with peridialysis CKD who visited the Department of Nephrology, First Affiliated Hospital of Zhengzhou University from January 2021 to June 2021 were collected and divided into 4 groups according to the presence or absence of heart failure and the level of left ventricular ejection fraction (LVEF), namely the non-heart failure group, heart failure with reduced ejection fraction (HFrEF) group (LVEF<40%), heart failure with mid-range ejection fraction (HFmrEF) group (40％≤LVEF<50％), and heart failure with preserved ejection fraction (HFpEF) group (LVEF≥50％). The NT-proBNP, echocardiography and other indicators of the 4 groups were compared. The value of plasma NT-proBNP in diagnosing heart failure, HFpEF, HFmrEF and HFrEF was analyzed by drawing receiver operating characteristic curve (ROC curve). Logistic regression analysis was used to analyze the related factors of heart failure in peridialysis CKD patients.Results:A total of 508 patients were included, including 11 cases in the HFrEF group, 29 cases in the HFmrEF group, 152 cases in the HFpEF group, and 316 cases without heart failure. The differences in age, 24-h urine volume, hemodialysis proportion, non-dialysis proportion, serum creatinine, estimated glomerular filtration rate, hemoglobin, serum albumin, C-reactive protein, NT-proBNP, cardiac troponin I, left ventricular internal diameter, LVEF, pulmonary artery systolic pressure, left ventricular end-diastolic volume, E/A value, septal thickness, and left ventricular posterior wall thickness among the four groups were statistically significant ( P < 0.05, respectively). A two-pair comparison (all P values corrected by Bonferroni method) revealed that the 24-h urine volume was higher in the non-heart failure group than in the other three groups (corrected P<0.05, respectively), while the proportion of hemodialysis patients and the levels of NT-proBNP and C-reactive protein were lower in the non-heart failure group than in the other three groups (corrected P<0.001, respectively); the levels of hemoglobin and serum albumin were lower in the HFpEF group than in the non-heart failure group (corrected P<0.001, respectively); troponin I was lower in the non-heart failure group than in the HFpEF group (corrected P<0.001), HFmrEF group (corrected P=0.001) and HFrEF group (corrected P<0.001), and troponin I was lower in the HFpEF group than in the HFrEF group (corrected P=0.008); LVEF was higher in the non-heart failure group than in the other three groups (corrected P<0.001, respectively), and LVEF in the HFpEF group was higher than in the HFmrEF and HFrEF groups (corrected P<0.001, respectively). For patients with peridialysis CKD, the cut-off values of plasma NT-proBNP for diagnosing or predicting heart failure, HFpEF, HFmrEF and HFrEF were 4 943.33 ng/L, 4 976.83 ng/L, 14 964.5 ng/L and 17 847.55 ng/L, respectively. Multivariate logistic regression analysis showed that NT-proBNP (every 500 ng/L increase, OR=1.390, 95% CI 1.287-1.501, P<0.001), LVEF ( OR=0.747, 95% CI 0.656-0.851, P<0.001) and 24-h urine volume (every 100 ml increase, OR=0.842, 95% CI 0.763-0.929, P=0.001) were independently correlated with heart failure. Conclusions:The cut-off value of plasma NT-proBNP for diagnosing or predicting heart failure in peridialysis CKD patients is much higher than that in patients with normal renal function. NT-proBNP, LVEF and 24-h urine volume are independently associated with heart failure in peridialysis CKD patients.

【Objective】 To explore the relationship between the storage time of leukodepleted red blood cells and transfusion adverse reactions by analyzing the occurrence of transfusion adverse reactions of patients after leukodepleted red blood cells transfusion from four hospitals. 【Methods】 By using the electronic medical record management system, the collection and transfusion dates of leukodepleted red blood cells from four hospitals in Enshi Prefecture from 2018 to 2022, as well as the information on transfusion adverse reactions, were retrieved. 【Results】 From 2018 to 2022, a total of 697 61 bags of leukodepleted red blood cells were transfused in four hospitals, resulting in 166 cases of transfusion adverse reactions, among which 93 were allergic reactions, 63 were non hemolytic febrile reactions, and 10 were others, with a total incidence rate of transfusion adverse reactions at 0.24%. The average storage time of leukodepleted red blood cells with and without transfusion adverse reactions was (20.25±6.31) and (19.88±5.50) days, respectively. With a storage time of 7 days as the threshold, the incidence of transfusion adverse reactions was the lowest for a storage time of 15~21 days. The incidence of transfusion adverse reactions of leukodepleted red blood cells in two groups (with storage days ≤21 days and >21 days) was not statistically significant(P>0.05). 【Conclusion】 Allergic reactions were the main type of transfusion adverse reaction caused by leukodepleted red blood cells, and the incidence of transfusion adverse reactions decreased and then increased with the prolongation of the storage time of leukodepleted red blood cells. There was no significant difference in the incidence of transfusion adverse reactions with leukodepleted red blood cells stored for ≤ 21 days and >21 days.
