Bibliometric analysis of research trends and active research areas in chimeric antigen receptor T cell therapy for hematologic malignancies.

In the past decade, chimeric antigen receptor (CAR) T-cells have successfully treated cancers, especially hematologic malignancies. Although many articles have been published on CAR T-cell therapy for hematologic malignancies, bibliometric analysis remains unexplored. This study aimed to investigate and analyze existing trends and active research areas on CAR T-cell therapy for hematologic malignancies, providing novel perspectives for clinical decision-making and scientific research. From 2000 to 2023, the Web of Science Core Collection was searched for articles published on CAR T-cells for the treatment of hematologic malignancies. Comprehensive visual analyses of annual publication, country, institutions, authors, co-cited references, and keywords were performed using CiteSpace software and VOSviewer. A total of 2,451 articles on CAR T-cells were published to treat hematologic malignancies from 01 January 2000 to 31 August 2023. The United States, China, and Germany were the top three nations in publications. In the keyword analysis, "immunotherapy" and "chimeric antigen receptor" were used most frequently. Moreover, the yellow node, which included terms such as "chimeric antigen receptor T cells," "efficacy," "CAR T-cell therapy," "toxicity," "CAR-NK," and "tumor microenvironment" were mostactive research areas. This study provided a comprehensive analysis of publications on CAR T-cell therapy for hematologic malignancies from 2000 to 2023.

Prognostic implications of synaptophysin, CD56, thyroid transcription factor-1, and Ki-67 in pulmonary high-grade neuroendocrine carcinomas

BackgroundThe correlation between the expression of immunohistochemical markers and the clinicopathological characteristics of pulmonary high-grade neuroendocrine carcinomas (HGNEC) and its impact on the clinical outcomes of individuals with HGNEC has not yet been explored. MethodsThis study enrolled patients diagnosed with HGNEC between April 2015 and July 2023. Based on the expression levels of synaptophysin (Syn), the neural cell adhesion molecule (CD56), thyroid transcription factor-1 (TTF-1), and Ki-67, a comprehensive analysis was conducted. This involved a comparison of clinicopathological characteristics, chemosensitivity, overall survival (OS), and progression-free survival (PFS). Furthermore, the study identified prognostic factors associated with patient survival through univariate and multivariate analyses. ResultsEighty-two patients were analyzed. Significant differences were identified in tumor stage (χ2 = 5.473, P = 0.019), lymphatic invasion (χ2 = 8.839, P = 0.003), and distant metastasis (χ2 = 5.473, P = 0.019), respectively, between the CD56 positive and negative groups. A significant difference in lymphatic invasion was observed (χ2 = 9.949, P = 0.002) between the CD56 positive and negative groups. A significant difference in vascular invasion was observed (χ2 = 5.106, P = 0.024) between the low and high Ki-67 groups. Compared to the Syn negative group, the Syn positive group had significantly shorter PFS (P = 0.006). Compared to the Syn negative group, the Syn positive group had significantly shorter OS (P = 0.004). The CD56 positive group also had significantly shorter OS than the CD56 negative group (P = 0.027). Univariate analysis revealed that tumor stage and Syn expression were associated with OS and PFS. Lymphatic invasion and CD56 expression were associated with OS. Multivariate analysis revealed that tumor stage was the strongest predictor of poor prognosis for OS (hazard ratio [HR] 0.551, 95 % confidence interval [CI] 0.328–0.927, P = 0.025) and PFS (HR 0.409, 95 % CI 0.247–0.676, P < 0.001). ConclusionsPositive expression of Syn was associated with reduced PFS and OS, while positive CD56 expression was correlated with a shorter OS in HGNEC. The TNM stage was an independent risk factor that significantly influenced PFS and OS in patients with HGNEC. More studies are needed to make further progress in future treatment.

Predictive value of suprasellar extension for intracranial infection after endoscopic transsphenoidal pituitary adenoma resection

ObjectiveTo investigate the relationship between suprasellar extension (SSE) and intracranial infection after endoscopic endonasal transsphenoidal approach (EETA) for pituitary adenoma resection.MethodsWe retrospectively analyzed 94 patients with suprasellar extended pituitary adenoma admitted to the Department of Neurosurgery of the Affiliated Hospital of Guilin Medical College from January 2018 to December 2021. We measured the preoperative magnetic resonance sagittal SSE and collected clinical data and divided the patients into groups according to the presence of postoperative intracranial infection. The critical value for the SSE was calculated by using a working characteristic curve for the subjects. The risk factors for intracranial infection after EETA resection of pituitary adenomas were analyzed by multivariate regression analysis.ResultsAmong the 94 patients, 12 cases (12.8%) were placed in the infection group and 82 cases (87.2%) in the non-infection group. The cut-off value for the SSE in the sagittal position was 15.6 mm, the sensitivity was 75%, the specificity was 87.8%, and the area under the curve (AUC) was 0.801. The coronary cut-off value for the SSE was 15.8 mm, the sensitivity was 66.7%, the specificity was 79.3%, and the AUC was 0.787. The SSE values in the sagittal and coronal positions were correlated with postoperative intracranial infection (P < 0.05). After univariate analysis, those with significant differences were included in the multivariate regression analysis. It was concluded that the extension distance of the tumor above the sella in the sagittal position was ≥ 15.6 mm, the tumor texture was hard, and the postoperative cerebrospinal fluid leakage were the independent risk factors for intracranial infection after EETA resection of suprasellar extended pituitary tumors (P < 0.05).ConclusionsThe value of SSE on sagittal MRI can predict intracranial infection in patients with suprasellar extended pituitary adenoma after endoscopic endonasal transsphenoidal resection. This finding recommends neurosurgeons pay more attention to the imaging characteristics of pituitary adenomas and select appropriate treatment plans in combination with the intraoperative conditions to reduce the incidence of intracranial infection.

Cost-effectiveness analysis of nivolumab versus placebo for relapsed malignant mesothelioma.

Although nivolumab has shown clinical benefits for relapsed malignant mesothelioma, its cost-effectiveness requires further investigation. This study aimed to evaluate the cost-effectiveness of nivolumab compared to placebo for relapsed malignant mesotheliomas from the perspective of the Chinese healthcare system. A three-state Markov model was developed based on data from the phase 3 randomized CONFIRM clinical trial. The drug cost and utility values for the health state were obtained from the relevant literature. The measured outcomes included quality-adjusted life-years (QALYs) and incremental cost-effectiveness ratio (ICER). Probabilistic and one-way sensitivity analyses (OWSA) were performed to assess the uncertainty of the model. Patients receiving nivolumab gained more health benefits (0.65 QALYs vs. 0.43 QALYs). The cost was higher ($25,806.08 vs. $9,310.74) than for patients in the placebo group, resulting in an ICER of $75,805.11/QALY, which was above the willingness-to-pay (WTP) threshold of three times per capita GDP ($35,864.61) in China. The result of OWSA indicated that the cost of nivolumab, the utility of the disease progression, and the discount rate were the most significant factors. Probabilistic sensitivity analysis suggested that the probability that nivolumab was not cost-effective aswas 100.00% above the specified WTP threshold. From the perspective of the Chinese healthcare system, nivolumab was not as cost-effective as placebo for relapsed malignant mesothelioma.

Amide proton transfer could be a surrogate imaging marker for predicting vascular cognitive impairment

BackgroudEmerging evidence suggests an overlap in the underlying pathways contributing to both cerebral small vessel disease (CSVD) and the neurodegenerative disease. Studies investigating the progression of CSVD should incorporate markers that reflect neurodegenerative lesions. ObjectiveWe aim to investigate whether Amide proton transfer (APT) can serve as a potential marker for reflecting vascular cognitive impairment (VCI). MethodParticipants were categorized into one of three groups based on their Montreal Cognitive Assessment (MoCA) scores: normal control group (age,54.9 ± 7.9; male, 52.9%), mild cognitive impairment (MCI) group (age,55.7 ± 6.9; male, 42.6%), or vascular dementia (VaD) group (age,57.6 ± 5.5, male, 58.5%). One way analysis of variance was performed to compare the demographic and APT variables between groups. Multiple logistic regression analysis wwas constructed to examine the relationship between APT values and VCI grouping. A hierarchical linear regression model was employed to examine the associations between patients' demographic factors, imaging markers, APT values, and MoCA. ResultsThe APT values of frontal white matter, hippocampus, amygdala, and thalamus were significantly different among different groups (p < 0.05). The APT values of frontal white matter, amygdala, and thalamus indicate a significant positive effect on MCI grouping. the APT values of frontal white matter, amygdala, and thalamus indicate a significant positive effect on VaD grouping. The demographic data, CSVD imaging markers and APT values can account for 5.1%, 20.1% and 27.7% of the variation in MoCA, respectively. ConclusionAPT imaging can partially identifying and predicting the occurrence of VCI.

Patients With Age-related Macular Degeneration Lack Knowledge and Self-management Skills of Age-related

Abstract Objective:To understand the status quo and factors influencing self-management behavior in patients with age-related macular degeneration, provide evidence for better self-management and develop self-management evaluation tools. Methods:A lot of 17 patients with age-related macular degeneration were interviewed using semi-structured questionnaires. The phenomenological research method was applied, and the data were collated according to Colaizzi's 7-step phenomenological analysis method. Results: The status quo and factors influencing self-management behavior in patients with age-related macular degeneration could be summarized into five themes:1)serious daily dysfunction caused by visual impairment and inability to cope with methods and skills; 2)lack of disease cognition, timely treatment, and poor compliance; 3)the presence of underlying diseases and poor management of comorbidity; 4)lack of disease health knowledge and display of bad habits and rebuilding healthy behavior motivation; 5)negative emotion . Conclusion: Patients with age-related macular degeneration have poor self-management knowledge and self-management ability. There is a need to strengthen the thematic popular science education of age-related macular degeneration at the social level, learn from advanced countries, collaborate with medical association and communities, and actively promote the development and application of visual rehabilitation training, social psychological intervention and self-management projects.Taken together these approaches could improve the self-management ability of patients with AMD.

Analysis of the Growth and Development of Children Born with ICSI of Epididymal and Testicular Spermatozoa: A Propensity Matching Study.

The study aimed to evaluate whether singleton live births (at 0, 1, 6, 12, and 24 months) following intracytoplasmic sperm injection (ICSI) using sperm of different origins (ejaculated or non-ejaculated sperm) are associated with the growth and development of children born. This was a retrospective cohort study conducted at a single center from January 2016 to December 2019. Follow-up data of the children were obtained from the Jiangsu Province Maternal and Child database. A total of 350 singleton live births after fresh embryo transfer (ET) with ICSI were included. Based on the origin of the sperm, the patients were divided into two groups: the ejaculated group (n = 310) and the non-ejaculated group (n = 40). Propensity score matching was used to control for multiple baseline covariates, resulting in 80 singleton live births (ejaculated sperm) matched to 40 singleton live births (non-ejaculated). The non-ejaculated group was further divided into two subgroups: the PESA group (n = 23) and the TESA group (n = 17). The primary outcome of the study was the growth and development of children. Secondary outcomes included the 2PN rate, high-cleavage embryo rate, blastocyst formation rate, and others. After matching parental age, BMI, occupation, and maternal serum AMH level, there was no significant difference found in the growth and development of children between the non-ejaculated and ejaculated group or the PESA group and TESA group, respectively. However, the 2PN rate and the blastocyst formation rate were higher in the ejaculated group compared to the non-ejaculated group (91.02 and 85.45, P = 0.002) and (67.37 and 56.06, P = 0.019), respectively. The high-quality cleavage embryo rate was also higher in the TESA group compared to the PESA group (85.06 and 65.63, P = 0.001). This study suggests that there are no significant differences in the growth and development of children born following ICSI using sperm of different origins (ejaculated or non-ejaculated). For nonobstructive azoospermia (OA) patients, sperm derived from the testis may be more effective than derived from the epididymis. However, due to the limited sample size of the non-ejaculated group in this study, further investigations with larger sample sizes are needed to validate these findings.
