The search period was from database establishment to March 31, 2023.Results:A total of 13 articles were included, including five guidelines, five evidence summaries, two expert consensus, and one clinical decision-making. A total of 33 recommendations for NBD management in spinal cord injury patients were summarized from five aspects of medical history assessment, medication management, physical therapy, diet and exercise, and health education.Conclusions:The best evidence for NBD management in spinal cord injury patients summarized is scientific and practical. Medical and nursing staff should selectively apply the best evidence based on clinical practice.

Objective:To explore the current situation of ageism among older adults in megacity communities and analyze its influencing factors.Methods:From November to December 2023, convenience sampling was used to select 200 older adults who visited the Niujie Community Health Service Center in Xicheng District, Beijing as the research subject. A survey was conducted on older adults using the General Information Questionnaire, Barthel Index, 15-Item Geriatric Depression Scale, Family Adaptation, Partnership, Growth, Affection and Resolve Scale (Family APGAR Scale), Rosenberg Self-Esteem Scale, Social Support Rating Scale, Lubben Social Network Scale, and Ageism Questionnaire. Multiple linear regression was used to analyze the influencing factors of ageism among older adults in the community.Results:A total of 200 questionnaires were distributed and 200 valid questionnaires were collected, with a valid response rate of 100.00% (200/200). The total score of ageism among 200 older adults in the community was (3.55±0.31), with objective and subjective scores of (3.59±0.28) and (3.50±0.48), respectively. Multiple linear regression showed that occupational status, pre-retirement or current work, family care, self-esteem, and social support were the influencing factors of ageism among older adults in the community ( P<0.05) . Conclusions:Ageism among older adults is influenced by various factors. Medical and nursing staff should focus on older adults who are retired, mainly engaged in physical work, and have poor family and social support when formulating intervention strategies. Community health workers should regularly organize activities to encourage older adults to actively participate, enhance their sense of social participation, reduce ageism, so as to promote healthy aging.

Objective:To delineate the clinical characteristics and outcomes associated with severe cardiac toxicity during the preconditioning phase of allogeneic hematopoietic stem cell transplantation (allo-HSCT) in patients with aplastic anemia (AA).Methods:This retrospective case series study included 31 patients with severe AA who underwent allo-HSCT and were diagnosed with severe cardiac toxicity at the Hematology Department of Peking University People′s Hospital from August 2012 to June 2022. The clinical manifestations of severe cardiac toxicity observed during the preconditioning process were assessed. Patient survival was assessed using the Kaplan-Meier method.Results:In this cohort of 31 patients, the median follow-up period was 9 days (range: 4-365 days). Severe cardiac toxicity manifested within 6 days after the initial cyclophosphamide (Cy) administration. Twenty patients died within 30 days of initiating Cy preconditioning, of which 16 patients died due to severe cardiac toxicity within 25 days. Patients whose cardiac function improved within 30 days post-preconditioning showed a median survival duration of 222 days ( n=11). Troponin I (TNI) levels in patients who died within 30 days of initiating Cy preconditioning began increasing on day 5 post-Cy, peaking sharply by day 9 after a notable rise on day 8. B-type natriuretic peptide (BNP) levels in patients who died within 30 days of initiating Cy preconditioning started to rise from day 1, stabilized between days 2 and 5, and then doubled daily from days 6 to 8, remaining elevated thereafter. Notably, the initial increases in BNP and TNI correlated with electrocardiogram (ECG) signs of low voltage and T-wave inversion in 83.87% of cases ( n=26). Most patients ( n=28, 90.32%) were administered corticosteroid therapy. In those with restored cardiac function, the ejection fraction returned to >50% within 30 days of initiating Cy preconditioning. Conclusions:Patients with severe cardiac toxicity during the preconditioning phase of allo-HSCT typically exhibit early, sustained, and marked elevations in myocardial damage markers, including BNP and TNI, accompanied by ECG abnormalities following Cy administration, with BNP often increasing first. These indicators are associated with rapid disease progression and high mortality. Prompt initiation of treatment upon clinical diagnosis is critical for improving survival outcomes.

Background/Aims: Low educational attainment is a well-established risk factor for nonalcoholic fatty liver disease (NAFLD) in developed areas. However, the association between educational attainment and the risk of NAFLD is less clear in China. Methods: A cross-sectional study including over 200,000 Chinese adults across mainland China was conducted. Information on education level and lifestyle factors were obtained through standard questionnaires, while NAFLD and advanced fibrosis were diagnosed using validated formulas. Outcomes included the risk of NAFLD in the general population and high probability of fibrosis among patients with NAFLD. Logistic regression analysis was employed to estimate the risk of NAFLD and fibrosis across education levels. A causal mediation model was used to explore the potential mediators. Results: Comparing with those receiving primary school education, the multi-adjusted odds ratios (95% confidence intervals) for NAFLD were 1.28 (1.16 to 1.41) for men and 0.94 (0.89 to 0.99) for women with college education after accounting for body mass index. When considering waist circumference, the odds ratios (95% CIs) were 0.94 (0.86 to 1.04) for men and 0.88 (0.80 to 0.97) for women, respectively. The proportions mediated by general and central obesity were 51.00% and 68.04% for men, while for women the proportions were 48.58% and 32.58%, respectively. Furthermore, NAFLD patients with lower educational attainment showed an incremental increased risk of advanced fibrosis in both genders. Conclusions In China, a low education level was associated with a higher risk of prevalent NAFLD in women, as well as high probability of fibrosis in both genders.

The increasing incidence of chronic kidney disease (CKD) has become a major global public health problem. Hypertension and CKD can cause and effect each other and often coexist. Controlling blood pressure is one of the core tasks in the treatment of CKD. Over the past 10 years, many large clinical studies have provided evidence-based medical evidence for the updating and revision of hypertension management guidelines, but there remains controversies in targets of blood pressure in hypertensive patients with CKD. Personalized and evidence-based management is the key to achieve effective control of blood pressure and slow the progression of CKD. This review will summary the epidemiological status of hypertensive patients with CKD and the progress related to the targets of controlling blood pressure in CKD.

Objective:To explore the clinical characteristics and prognosis of newly diagnosed CD5-positive diffuse large B-cell lymphoma (DLBCL).Methods:The clinical data of 19 newly diagnosed CD5-positive DLBCL patients in Tenth People's Hospital of Tongji University and Ninth People's Hospital of Shanghai Jiao Tong University School of Medicine between January 2015 and December 2018 were retrospectively analyzed. Their clinical characteristics and laboratory indexes were observed; Kaplan-Meier method was used for survival analysis, and Cox proportional risk model was used to make multifactor analysis of the prognostic factors.Results:The median age of 19 newly diagnosed CD5-positive DLBCL patients was 63 years (34-76 years). All 19 patients included 13 cases with Ann Arbor Ⅲ-Ⅳ stage; 12 cases with lactate dehydrogenase higher than the normal value limit, 9 cases with international prognostic index scores ≥ 4, 13 cases with B symptoms, 10 cases with Ki-67 positive index ≥ 80%, 15 cases with more than 1 lymph extra nodal organ involvement and 8 cases with tumor mass (mass diameter ≥ 7 cm). The 2-year progression-free survival (PFS) rate was 47.4% and 2-year overall survival (OS) rate was 63.2%. Univariate analysis showed that Ann Arbor stage, tumor mass, lymph extra nodal involvement and ≥ 4 courses of intrathecal injection were associated with OS (all P < 0.05). Multivariate analysis showed that Ann Arbor stage (stage Ⅰ-Ⅱ vs. stage Ⅲ-Ⅳ: HR = 0.158, 95% CI 0.031-0.803, P = 0.026), tumor mass (tumor diameter < 7 cm vs. tumor diameter ≥ 7 cm: HR = 0.076, 95% CI 0.009-0.637, P = 0.018)and ≥ 4 courses of intrathecal injection (yes vs. no: HR = 9.130, 95% CI 1.062-78.157, P = 0.044) were independent influencing factors for OS. Conclusions:Newly diagnosed CD5-positive DLBCL is highly aggressive and susceptible to extra nodal infiltration. Ann Arbor stage Ⅲ-Ⅳ, tumor mass, and not receiving ≥ 4 courses of intrathecal injection are independent risk factors affecting the prognosis of CD5-positive DLBCL patients.

Objective:To investigate the safety and efficacy of haplo-identical hematopoietic stem cell transplantation (haplo-HSCT) conditioning with the same dosage form of antithymoglobulin (ATG) in patients with severe aplastic anemia (SAA) failure to ATG.Methods:This was a retrospective cohort study. A total of 65 patients with SAA who failed ATG treatment and received haplo-HSCT conditioning with the same dosage of ATG at the Institute of Hematology, Peking University People′s Hospital between July 2008 and October 2020 were included as the ATG treatment failure group. An additional 65 SAA patients who applied ATG for the first time during haplo-HSCT were randomly selected by stratified sampling as the first-line haplo-HSCT group. Baseline clinical data and follow-up data of the two groups were collected. Conditioning-related toxicity within 10 days after ATG application and long-term prognosis were analyzed. The Kaplan-Meier was used to calculate the overall survival rate, and the Log-rank test was applied to compare the rates of the two groups.Results:In the ATG treatment failure group, there were 36 males and 29 females, and the age at the time of transplantation [ M ( Q1, Q3)] was 16 (8, 25) years. In the first-line haplo-HSCT group, there were 35 males and 30 females, with a median age of 17 (7, 26) years. Within 10 days of ATG application, the incidence of noninfectious fever, noninfectious diarrhea, and liver injury in the ATG treatment failure group was 78% (51 cases), 45% (29 cases), and 28% (18 cases), respectively, and in the first-line haplo-HSCT group was 74% (48 cases), 54% (35 cases), and 25% (16 cases), respectively; the difference between the two groups was not statistically significant for any of these three parameters (all P>0.05). For graft-versus-host disease (GVHD), there was no significant difference between the ATG treatment failure group and the first-line haplo-HSCT group in the development of 100 day Ⅱ to Ⅳ acute GVHD (29.51%±0.35% vs. 25.42%±0.33%), Ⅲ to Ⅳ acute GVHD (6.56%±0.10% vs. 6.78%±0.11%), and 3-year chronic GVHD (26.73%±0.36% vs. 21.15%±0.30%) (all P>0.05). Three-year overall survival (79.6%±5.1% vs. 84.6%±4.5%) and 3-year failure-free survival (79.6%±5.1% vs. 81.5%±4.8%) were also comparable between these two groups (both P>0.05). Conclusions:Compared with no exposure to ATG before HSCT, similar early adverse effects and comparable survival outcomes were achieved in patients with SAA who failed previous ATG treatment and received haplo-HSCT conditioning with the same dosage form of ATG. This might indicate that previous failure of ATG treatment does not significantly impact the efficacy and safety of salvaging haplo-HSCT in patients with SAA.
