Intravascular large B cell lymphoma (IVLBCL) is a rare, aggressive subtype of diffuse large B cell lymphoma, with nasal turbinate involvement being uncommon. We report a 51-year-old woman with a 1-month history of fever of unknown origin. Laboratory findings showed cytopenia, hypertriglyceridemia, elevated ferritin, increased soluble CD25, and bone marrow hemophagocytosis. No infectious cause was identified. PET-CT revealed abnormal 18F-fluorodeoxyglucose (FDG) uptake in the nasal turbinates. Turbinate biopsy revealed tumor cells localized predominantly within vascular lumens, positive for CD20, BCL6, PAX5, and MUM1, with a Ki-67 index >60%, confirming a diagnosis of IVLBCL with hemophagocytic lymphohistiocytosis (HLH). The patient received one cycle of the DEP regimen (liposomal doxorubicin, etoposide, and methylprednisolone) for HLH, followed by five cycles of R-CHOP (rituximab, cyclophosphamide, doxorubicin, vincristine, and prednisone) and consolidation with auto-HSCT, achieving sustained complete remission. IVLBCL outcomes are heterogeneous; early diagnosis and prompt treatment improve survival, and R-CHOP plus auto-HSCT may be an effective strategy.

In recent years, sleep problems among nurses have become a prominent social focus, and sleep disorders are widespread among nurses. ICU nurses are more prone to problems such as decreased sleep quality, shorter sleep duration, and daytime sleepiness than nurses in other departments due to special and complex work environments. Sleep disorders seriously affect the physical and mental health of ICU nurses and the quality of nursing care. This paper reviews the influencing factors, interventions, and assessment tools for sleep disorders among ICU nurses in order to inform the development of effective interventions.

Objective To construct a nonparametric proportional hazards (PH) model for mixed informative interval-censored failure time data for predicting the risks in heart transplantation surgeries. Methods Based on the complexity of mixed informative interval-censored failure time data, we considered the interdependent relationship between failure time process and observation time process, constructed a nonparametric proportional hazards (PH) model to describe the nonlinear relationship between the risk factors and heart transplant surgery risks and proposed a two-step sieve estimation maximum likelihood algorithm. An estimation equation was established to estimate frailty variables using the observation process model. I-spline and B-spline were used to approximate the unknown baseline hazard function and nonparametric function, respectively, to obtain the working likelihood function in the sieve space. The partial derivative of the model parameters was used to obtain the scoring equation. The maximum likelihood estimation of the parameters was obtained by solving the scoring equation, and a function curve of the impact of risk factors on the risk of heart transplantation surgery was drawn. Results Simulation experiment suggested that the estimated values obtained by the proposed method were consistent and asymptotically effective under various settings with good fitting effects. Analysis of heart transplant surgery data showed that the donor's age had a positive linear relationship with the surgical risk. The impact of the recipient's age at disease onset increased at first and then stabilized, but increased against at an older age. The donor-recipient age difference had a positive linear relationship with the surgical risk of heart transplantation. Conclusion The nonparametric PH model established in this study can be used for predicting the risks in heart transplantation surgery and exploring the functional relationship between the surgery risks and the risk factors.

Objective To compare and analyze the differences between customized models and commercial universal models in the segmentation of organs-at-risk in cervical cancer,and to investigate the feasibility of customized models.Methods A retrospective analysis was conducted on 270 cervical cancer patients.Senior clinicians manually delineated organs-at-risk,including the bladder,rectum,small intestine,pelvic bone marrow,femoral heads,and kidneys.The cases were randomly selected to develop customized models,with 202 cases allocated to the training set,38 cases to the test set,and 30 cases to the validation set.The universal and customized models were used for segmentation on the test set,and the automatic segmentation results obtained by the two models were compared with manual segmentation results to assess the performance of the customized model.Results Both customized model and universal model had comparable DSC values to manual segmentation,demonstrating satisfactory delineation outcomes(DSC values ranging from 0.7 to 0.9).However,in terms of deviation of centroid and 95％Hausdorff distance,the customized model surpassed the universal model.Conclusion Compared with the universal model,the customized model offers superior accuracy in delineating the structures of organs-at-risk in cervical cancer.As the customized model is optimized based on specific datasets,it provides precise support for clinical decision-making and holds promising applications in the treatment of cervical cancer.

Objective:To evaluate the clinical efficacy of C-type endoscopic submucosal dissection (C-ESD) for rectal neuroendocrine tumors (NEN).Methods:The retrospective analysis was performed on data of 55 patients who underwent ESD for rectal NEN at the Department of Endoscopy in Quanzhou First Hospital from January 2018 to July 2021. Patients were divided into the C-ESD group ( n=28) and the conventional ESD group ( n=27). The dissection time, the dissection speed, the number of submucosal injections, the enbloc resection rate, the curative resection rate and the rate of postoperative complications of the two groups were compared. Results:There were no statistically significant differences in basic information between the two groups ( P>0.05). The dissection time was 13.8±4.2 min in the C-ESD group and 19.9±3.9 min in the conventional ESD group with statistically significant difference ( t=5.649, P<0.001). The dissection speed in the C-ESD group was 0.08±0.04 cm 2/min, which was faster than 0.06±0.04 cm 2/min in the conventional ESD group ( t=2.218, P=0.031). The number of submucosal injections in the C-ESD group was less than that in the conventional ESD group [2 (1, 2) VS 3 (2, 3), Z=-8.701, P<0.001]. The lesions were enbloc resected in both groups. The curative resection rate in the C-ESD group was 100.0% (28/28) and 88.9% (24/27) in the conventional ESD group with statistically significant difference ( P=0.011). There were 7 cases of postoperative complications in the conventional ESD group, including 1 delayed bleeding, 5 delayed perforation and 1 muscularis propria injury, while no postoperative complications occurred in the C-ESD group ( P=0.004). Conclusion:C-ESD is a safe and effective treatment strategy for colorectal NEN, which can shorten the dissection time, improve the dissection speed, reduce the number of submucosal injections, improve the curative resection rate, and reduce complications.
