The general data, blood routine, liver and kidney function, glucose metabolism and lipid metabolism of 11 922 participants who underwent physical examination at the Health Management Center of the Second Xiangya Hospital of Central South University from January 2019 to December 2019 were collected. Clinical characteristics and independent factors of patients with discordance between HbA1c and FPG were evaluated and analyzed. The prevalence of HbA1c-defined diabetes and prediabetes (respectively 8.13%, 34.79%) were significantly higher than that in FPG-defined diabetes and prediabetes (respectively 4.70%, 8.97%) (χ2=2 635.940; P<0.001). The prevalence of inconsistence between HbA1c and FPG was 35.65% and increased with increasing age. This inconsistence mainly occurred in population with HbA1c:5.7%-6.0% and FPG<5.6 mmol/L, followed by population with HbA1c:6.1%-6.4% and FPG<5.6 mmol/L. The risk factors of inconsistency included advanced age, overweight or obesity, hypoalbuminemia, dyslipidemia and hyperuricemia. Among these special participants, compared with participants under 45 years old, participants with over 45 years of age ( OR=3.525, 95% CI: 3.216-3.863, P<0.001) were more likely to have inconsistence between HbA1c and FPG; and overweight participants ( OR=1.474, 95% CI: 1.341-1.620, P<0.001) or obese participants ( OR=1.856, 95% CI: 1.633-2.110, P<0.001) are prone to have the inconsistence than those with normal weight.

Objective:To systematically evaluate and Meta-synthesize qualitative studies on the home management needs of patients with spinal cord injury (SCI) to understand their actual self-management needs and improve the quality of home management for patients with SCI in China.Methods:A comprehensive search was conducted in databases including CNKI, Wanfang, CBM, PubMed, Embase, Web of Science, CINAHL, and Cochrane Library for qualitative research on the home management needs of patients with SCI, with a search timeframe up to November 30, 2023. The methodological quality of the included studies was evaluated using the Joanna Briggs Institute (JBI) Qualitative Assessment and Review Instrument (2016). Results were integrated and analyzed using Meta-synthesize methods.Results:A total of 15 studies were included, from which 58 distinct research findings were extracted. These were categorized into 10 new categories, which were further integrated into four main results: the need for positive emotional support, daily living-related needs, healthcare service needs, and social support needs.Conclusions:Healthcare providers should deeply understand the home management needs of patients with SCI. Utilizing artificial intelligence technology, an integrated support model encompassing hospital, home, and society can be constructed. Establishing a comprehensive home rehabilitation platform for patients with SCI can focus on psychological issues and enhance social support levels, thereby improving patients' quality of life.

This article summarizes the current research status of health-related quality of life (HRQOL) in sepsis patients after discharge, including the current states of short-term and long-term HRQOL, influencing factors, and interventions. Recent studies have shown that both short-term and long-term HRQOL of sepsis patients after discharge are suboptimal. Given the numerous and long-lasting factors that affect HRQOL, it is recommended that individualized nursing interventions targeting these factors be implemented in clinical practice. Further research should explore effective methods to improve the HRQOL of sepsis patients.

Objective:To study the willingness of the medical staff of tertiary hospitals to be dispatched to work for a long time at the district hospitals under the " municipal trusteeship of district-ownership hospitals" mode, and explore the key factors that affect their long-term willingness, for references of optimizing the incentive system of the model.Methods:A questionnaire was designed as guided by the two-factor theory. In May 2019, a typical sample survey was made to investigate 103 medical staff of two tertiary hospitals in Beijing on their willingness to be dispatched to hospitals of district ownership. The survey covered such aspects as their basic personal information, hygiene factors(family responsibility, interpersonal connections expansion, mobilization and encouragement of leaders, etc.), and incentive factors(personal career development, greater potential giving play to their own talents, self-achievement, etc.). Descriptive analysis and univariate hypothesis testing were used to compare the differences of the dispatch willingness of staff of different characteristics. Meanwhile, an ordinal multinomial logistic regression model was built to analyze the influence factors of long-term dispatch willingness of these staff along with individual in-depth interviews.Results:The medical staff when they were dispatched to work at the entrusted hospitals for a long time, were concerned mostly with top six factors. These factors refered to a reasonable incentive(rewards)mechanism, family responsibility, colleague evaluation of the entrusted hospital, interpersonal connections expansion, personal career development, and potential unlocking. Those staff with dispatch experience had higher willingness to be dispatched than those without( P <0.05). The former saw higher of their personal career development resulting from the dispatch(3.91 points), while the latter saw higher their post-dispatch salary incentive mechanism(3.95 points). Compared with common medical staff, medium and high level management staff were more willing to be dispatched for a long time( H=14.536, P<0.001). Leadership mobilization in hygiene factors and personal career development in incentives factors were the key drivers for the long-term willingness of medical staff to be dispatched( P<0.05). Conclusions:The willingness of medical staff to be dispatched for a long time needs to be strengthened in the " municipal trusteeship of district-ownership hospitals" mode. Managers of the district-ownership hospitals should take into full consideration, the needs of different categories and levels of medical staff dispatched, guarantee the remuneration and performance pay of these staff, and enable their career track planning, hence mobilizing their incentives, and increase their willingness to work at such hospitals for a long time.

[Objective] To assess the data characteristics of quality monitoring indicators for red blood cell (RBC) preparations, so as to provide reference for continuous improvement of blood quality. [Methods] The quality inspection data of 6 types of RBC preparations from Chongqing blood center from 2019 to 2023 were summarized. For the same indicators, the numerical range of quality indicators was monitored by comparing different types of preparations with the national standard GB18469. The loss and/or damage to RBCs caused by different preparation process were compared, and the impact of different preparation processes on the quality of RBCs was discussed. [Results] The appearance and sterility test compliance rates of the six types of RBC preparations were both 100%, while the compliance rates of other items were all ≥75%. The compliance rate of hematocrit for suspended RBCs was the lowest at 75%, with a median of 0.52, which was close to the lower limit of GB18469, while the medians of hematocrit for the other types were all at the midline level of GB18469. The Hb content for different types of RBCs was significantly higher than the corresponding requirements of GB18469 (P<0.05). The hemolysis rate at the end of storage for different types of RBCs was significantly lower than the requirements of GB18469 (P<0.05). The 1 U leukoreduction process resulted in a hemoglobin content loss of about 5% and had a significant impact on the hemolysis rate at the end of storage (P<0.05). The washing process resulted in a hemoglobin content loss of <3% and had no significant impact on the hemolysis rate at the end of storage (P>0.05). The concentration process resulted in a hemoglobin content loss of <3% and had a significant impact on the hemolysis rate at the end of storage (P<0.05). [Conclusion] The impact of different processes on RBC preparations is within a controllable range and meets the requirements of GB18469. The quality monitoring data can provide a reference for clinical blood selection, effectiveness evaluation and revision of related standards.

【Objective】 This study endeavors to introduce the statistical process control (SPC) method to analyze the quality control index concerning red blood cells in additive solution with leukocytes reduced, with the aspiration to advance the effective utilization of blood quality control data, thereby providing empirical foundations for the continual enhancement of blood quality. 【Methods】 Between 2020 and 2022, test data pertaining to the quality control index of red blood cells in additive solution with leukocytes reduced were amassed from six blood stations in Chongqing area. Utilizing Minitab software, the SPC analysis was carried out, p-control charts were delineated, the non-conformance rates of each quality control index along with their 95% confidence intervals were computed, as well as the Process Capability Index (Z value). 【Results】 In accordance with the Whole Blood and Blood Components Quality Requirements, the appraisal of the quality control indexes for red blood cells in additive solution with leukocytes reduced manifested a conformity rate of 100% for appearance, end-of-storage hemolysis rate and sterility test. Nonetheless, the conformity rates for volume, hemoglobin, hematocrit and residual leukocytes did not attain 100%, albeit all were ≥75%. Through the employment of binomial distribution-based p-control charts, the controlled state of the production process was discerned. Although the overarching conformity rate satisfied the national standard stipulations, it was discerned that there were out-of-control points concerning volume, hemoglobin, hematocrit, and residual leukocytes across different institutions, exhibiting palpable trends. The non-conformance rates of all quality control indexes were less than 25%, yet at a 95% confidence level, the residual leukocyte counts from institutions B, C, E, and F did not adhere to the stipulations (exceeding 25%). By architecting the ability evaluation index Z value for count data process capability analysis, it was unveiled that the volume of institution E, the hematocrit of institutions B, C, and F, and the residual leukocytes Z values of all six blood collection and supply institutions were below 2, hinting at avenues for amelioration. 【Conclusion】 The SPC method anchored in binomial distribution exhibits substantial application merit in blood component quality management, facilitating real-time surveillance of blood collection, preparation, and storage procedures.

Objective:To investigate the vaccination status, characteristics and prognosis of patients suffering from a combination of COVID-19 and chronic lymphocytic anemia (CLL) in China.Methods:Clinical data of 328 patients with chronic lymphocytic leukemia (CLL) who were first diagnosed with COVID-19 and treated in the Department of Hematology of Jiangsu Provincial People’s Hospital between November 2022 and February 2023 were retrospectively analyzed. Univariate and multivariate analysis of data of patients with severe/critical COVID-19 were conducted by applying the binary logistic regression model.Results:The median age of the CLL patients was 60 (24-87) years. 23.5% (77/328) of these patients suffered from severe/critical COVID-19 infection. Univariate analysis of the data demonstrated that a combination of factors including age >67 years ( OR=2.15, 95% CI 1.24- 3.73, P=0.006), diabetes ( OR=2.09, 95% CI 1.05-4.20, P=0.037), chronic hepatitis B ( OR=2.91, 95% CI 1.30-6.51, P=0.010), CLL progressive ( OR=3.79, 95% CI 1.57-9.15, P=0.003) and CD20 antibody-based treatments within three months prior to the COVID-19 infection ( OR=2.79, 95% CI 1.35-5.77, P=0.006) were the risk factors for severe/critical COVID-19. According to the multivariate analysis, CLL progressive ( OR=2.98, 95% CI 1.10-8.10, P=0.033) was an independent risk factor for severe/critical COVID-19 and administration of the BTK (Bruton tyrosine kinase) inhibitor monotherapy might exert a protective effect and influence a positive outcome of the COVID-19 infection ( OR=0.38, 95% CI 0.16-0.90, P=0.028). Among the 242 patients who were followed up until October 2023, 9.1% (22/242) had multiple subsequent COVID-19 infections (≥3), and 2.1% (5/242) had persistent COVID-19 infections (patients with persistent positive test for the SARS-CoV-2 antigen testing until missing follow-up for any reason). The peak value of the anti-SARS-CoV-2-IgG titres was observed between three and four months post symptom onset (median: 3.511 S/CO vs 1.047 S/CO, P<0.05). The levels of immunoglobulin A gradually decreased following infection with COVID-19, and its trough levels were attained between two to four weeks post infection (median: 0.30 g/L vs 0.74 g/L, P<0.05). According to this study the mortality of patients suffering from a combination of COVID-19 infection and CLL was 2.7% (9/328), and the main reason for their death was respiratory failure and heart failure. Conclusions:A low rate of COVID-19 vaccination and a high rate of severe/critical COVID-19 infection was observed in the CLL patients. CLL progressive was associated with severe/critical COVID-19. Anti-CD20-based treatments received within the past three months might be a risk factor for exacerbation of COVID-19 infection, whereas a monotherapy with BTK inhibitors exert a protective effect and improve outcome of COVID-19 infection.
