Association and Contribution of Patient and Bereaved Family Background to Outcomes of Survivor Surveys

A secondary analysis of data from national bereavement surveys conducted in 2014, 2016, and 2018 was conducted with the aim of identifying the contribution of various patient and bereavement backgrounds to the outcomes of the Bereavement Survey. The data were evaluated in terms of structure and process of care (CES), achievement of a desirable death (GDI), complexity grief (BGQ), and depression (PHQ-9). The large data set and comprehensive analysis of bereavement survey outcomes clarified the need for adjustment of confounding variables and which variables should be adjusted for in future analyses. Overall, the contribution of the background factors examined in this study to the CES (Adj-R2=0.014) and overall satisfaction (Adj-R2=0.055) was low. The contribution of the GDI (Adj-R2=0.105) was relatively high, and that of the PHQ-9 (Max-rescaled R2=0.200) and BGQ (Max-rescaled R2=0.207) was non-negligible.

Analysis on phenotype and genotyping of CisAB subtypes: 12 Cases / 中国输血杂志

【Objective】 To analyze and master the serological and genetic characteristics of the samples with CisAB subtype and their genetic background. 【Methods】 From January 2018 to January 2022, blood samples with discrepant ABO blood typing results, from Zhengzhou voluntary blood donors and hospital patients, were subjected to phenotypic classification using micro column gel card and tube method, as well as amplification of exons 6 and 7 in ABO gene using PCR. The pedigrees of individuals with the same CisAB subtype but different serological typing results in the same family were analyzed. 【Results】 11 The forward typing of 12 samples was AB type, and unexpected antibodies against weaker antigens were found in 11 serum samples, including 9 cases with strong antigen A, 2 cases with strong antigen B, and 1 case with consistent forward and reverse typing results. Gene sequencing confirmed that 11 cases were CisAB01 subtype and 1 case was CisAB05 subtype.Among them, 7 cases had the genotype of CisAB01/O and serological phenotype of A2B3; 2 cases had the genotype of CisAB01/B and phenotype of A2B; 2 cases had the genotype of CisAB01/A and serological phenotype of A1Bx and A1B3; 1 case had the phenotype of AxB. In the CisAB01 family, 1 case of CisAB01/O with A2B3 phenotype and 1 case of CisAB01/B with A2B phenotype were detected. In the CisAB05 family, 2 CisAB05/O01 and 1 CisAB05/O02 were detected. 【Conclusion】 The serological phenotypes of different individuals in the same CisAB01 family can be different when paired with different ABO alleles. It is advisable to accurately identify the CisAB subtype genes with molecular biological methods to ensure blood transfusion safety.
