Objective:To investigate the longitudinal stability of the Mini-Mental State Examination (MMSE), Montreal Cognitive Assessment (MoCA), and the Activity of Daily Living Scale (ADL).Methods:The longitudinal cognitive assessment results of 68 dementia patients admitted to the Dementia and Leukoencephalopathy Outpatient Clinic, Department of Neurology, Peking Union Medical College Hospital, from January 2021 to January 2024, were retrospectively analyzed, including the total and sub-items scores of the MMSE, MoCA, and ADL. Two different rules were applied to analyze the abnormality rates: rule 1, where the current test result being better than the previous one was considered an abnormality; rule 2, where the current test result being better than the previous average score was considered an abnormality (If a patient had only 2 cognitive assessments, rule 2 was considered the same as rule 1). Two rules were used to analyze the abnormality rates of the scales. The statistical analyses were repeated after excluding patients with possible anxiety and depression status.Results:In assessing the total score stability, MMSE showed the lowest abnormality rates [27.2% (31/114) under rule 1 and 29.8% (34/114) under rule 2], while MoCA had the highest abnormality rates [41.3% (26/63) and 46.0% (29/63), respectively]. The ADL abnormality rates were 27.7% (23/83) and 33.7% (28/83), respectively. Among MoCA sub-items, category cue, multiple choice cue, second memory trial, orientation, and clock showed higher abnormality rates [31.7%(20/63), 30.2%(19/63), 23.8%(15/63), 22.2%(14/63), 22.2%(14/63), respectively]. After excluding population with possible anxiety and depression status, the relative abnormality rates of MMSE and ADL sub-items did not significantly change, while the abnormality rate of orientation in MoCA sub-items decreased relatively.Conclusion:The MMSE and ADL exhibit good stability in long-term monitoring of dementia patients, serving as essential tools for assessing and following up cognitive changes.

【Objective】 To retrospectively analyze the indexes of autologous blood transfusion during heart valve replacement, in order to provide reference for allogeneic blood transfusion during heart valve replacement surgery under direct vision. 【Methods】 The data of 180 patients who underwent heart valve replacement in our hospital from January 2020 to December 2021 were analyzed retrospectively. The patients were divided into allogeneic and non-allogeneic blood transfusion group based on whether allogeneic blood was transfused during the operation, and the general data and 24 hours pre- and post-operative clinical examination indexes were compared. 【Results】 Multivariate logistic regression analysis showed that age (OR=1.110, 95% CI: 1.058-1.165, P<0.05) and intraoperative cardiopulmonary bypass time (OR=1.062, 95% CI: 1.038-1.086, P<0.05) were risk factors for allogeneic blood transfusion, and preoperative Hb content (OR=0.910, 95%CI: 0.868-0.953, P<0.05) was a protective factor. The RBC count(4.16±0.73 vs 4.52±0.71)×10¹²/L and Hb(120.94±17.97 vs 136.57±19.33) g/L at 24 hours preoperative in the allogeneic transfusion group were lower than those in the non-allogeneic transfusion group, and the RBC(3.51±0.53 vs 4.13±0.78)×10¹²/L, Hb(114.15±11.68 vs 124.79±14.96)g/L and platelet count(124.28±32.11 vs 148.29±26.62)×10⁹/L at 24 hours postoperative were significantly lower than those in the non-allogeneic transfusion group (P<0.05). 【Conclusion】 Age and intraoperative cardiopulmonary bypass time are the risk factors for autologous and allogeneic blood transfusion during heart valve replacement under direct vision, and the preoperative Hb content is a protective factor. It is necessary to evaluate the symptomatic treatment of patients before operation and reduce allogeneic blood transfusion.

This article focuses on a case study of sitosterolemia in a child who initially presented with hemolytic anemia and thrombocytopenia. Sitosterolemia is a rare autosomal recessive lipid metabolism disorder, difficult to diagnose due to its non-typical clinical manifestations. The 8-year-old patient was initially misdiagnosed with pyruvate kinase deficiency. Comprehensive biochemical and molecular biology analyses, including gene sequencing, eventually led to the correct diagnosis of sitosterolemia. This case highlights the complexity and diagnostic challenges of sitosterolemia, emphasizing the need for increased awareness and accurate diagnosis in patients presenting with similar symptoms.

Objective To develop a comprehensive family integrated care program for very low birth weight in-fants and to investigate the initial application effect of the program.Methods The family integrated care program for very low birth weight infants was developed using semi-structured interviews,a comprehensive literature review,and an expert consensus.A non-synchronous controlled trial was subsequently carried out.Between January and May 2023,35 participants accompanied by their parents for a minimum of 6 hours daily over a span of at least 3 days,were consecutively selected as an intervention group.Between January and May 2022,35 participants in the control group were treated with routine closed neonatal intensive care unit model.The application effect of the pro-gram on the clinical outcomes of very low birth weight infants was assessed,such as weight gain rate during hospi-talization,breastfeeding days,incidence of late-onset sepsis,incidence of extrauterine growth restriction at discharge,TIMP level at corrected gestational age of 37 weeks and hospitalization days.Results The authority coefficient of the 8 invited experts specializing in neonatal nursing and nursing management was 0.925.A comprehensive pro-gram was developed,consisting of 2 stages—preparation and implementation,and addressing 7 key themes:staff team formation and training,environmental support,assessment,parental training,family-integrated care implementation,peer support,and comprehensive communication.No shedding cases occurred during the application of the program.The outcomes indicated that the intervention group experienced a higher rate of weight gain and more days of breast-feeding compared to the control group,and the incidence of extrauterine growth retardation upon discharge was also lower,with statistically significant differences(all P＜0.05).However,there were no significant differences in other clinical outcomes(all P＞0.05).Conclusion The family integrated care program for very low birth weight infants de-veloped in this study is scientifically grounded,comprehensive,and practical.The implementation of this program can promote the weight gain and breastfeeding among very low birth weight infants,reduce the occurrence of extrauter-ine growth restriction upon discharge,and does not increase the incidence of late-onset sepsis.

Objective:To analyze the clinical and imaging features of patients with COVID-19-related osmotic demyelination syndrome (ODS).Methods:COVID-19-related ODS cases diagnosed in the Department of Neurology, Peking Union Medical College Hospital from January 2020 to September 2023 were retrospectively reviewed. And their past medical history, possible triggers, clinical manifestations, imaging manifestations, treatment and prognosis were summarized.Results:A total of 5 patients with COVID-19-related ODS were included. Electrolyte disturbances acted as an inducement of ODS in all patients (5/5),4 of whom with hyponatremia. Four of 5 patients first presented with disturbance of consciousness, followed by predominant dystonia. Imaging of all patients (5/5) showed isolated extrapontine myelinolysis (EPM). With the prolongation of the course of disease, such signal intensity could return to normal, and lesions showed atrophic changes in some patients. The patients′ clinical symptoms were partly relieved within a few days to a few months after treatment.Conclusions:COVID-19-related ODS is mostly associated with hyponatremia, and EPM is more common. COVID-19 should be considered as a risk factor for ODS.

A young female patient with acne and elevated testosterone level underwent plasma steroid hormones testing and found a significant increase in aldosterone. We excluded testing interference and verified the absence of hypertension, hypokalemia, and adrenal occupancy, as well as primary and secondary hyperaldosteronism. During follow-up, a temporal correlation was found between aldosterone levels and the use of drospirenone and ethinylestradiol tablets. It was observed that the combination of drospirenone and ethinylestradiol could lead to the increase of aldosterone level and the concentration ratio of aldosterone to direct renin through different mechanisms. Drospirenone exerts an antagonistic effect on mineralocorticoid receptor to prevent the development of hypertension or hypokalemia. In clinical practice, it is necessary to pay attention to the effect of this drug on screening markers for primary aldosteronism. In the laboratory examination, when female patients with no symptoms of hypertension and hypokalemia but with elevated aldosterone levels are encountered, it can be verified whether they have a history of use of compound estrogen-progestin such as drospirenone and ethinylestradiol tablets, and appropriate tips are provided in the report.

【Objective】 To analyze the risk factors for intraoperative massive red blood cell (RBC) transfusion in patients with Stanford type A aortic dissection (TAAD), in order to develop a risk-prediction model and validate its predictive effect. 【Methods】 The clinical data of 233 patients with TAAD admitted to our hospital from July 2018 to June 2021 (modeling set) were retrospectively analyzed. They were divided into routine transfusion group (n=128, RBC≤8 U) and massive transfusion group (n=105, RBC>8 U). Risk factors for intraoperative massive RBC transfusion in TAAD patients were analyzed by multivariate logistic regression and a risk prediction model was developed. Calibration curve and receiver operating characteristic (ROC) curve were used to assess the accuracy and discrimination of the model. In addition, 61 TAAD patients admitted to our hospital from July 2021 to May 2022 (validation set) were used for external validation. 【Results】 The rate of intraoperative massive RBC transfusion in 233 TAAD patients was 45.06% (95% CI: 38.59%-51.69%). Logistic analysis showed that women, age >50 years, preoperative Hb≤131.50 g/L, intraoperative bleeding >720 mL, and CPB time >155 min were independent risk factors for massive intraoperative RBC transfusion (P<0.05). The intraoperative risk prediction model formula for massive RBC infusion was: -4.427+ 0.925×gender+ 1.461×age+ 2.081×preoperative Hb+ 1.573×bleeding volume+ 2.823×CPB time. The area under the ROC curve of the modeling set and validation set were 0.904 (95% CI: 0.865-0.943) vs 0.868 (95%CI: 0.779-0.958), and the slopes of the calibration curves all converged to 1, indicating that the model predicted the risk of intraoperative massive RBC infusion in TAAD patients in good consistency with the actual risk of massive infusion. The decision curve shows that the model exhibits a positive net benefit with a threshold probability of 0.15-0.67 and has a high clinical application value. 【Conclusion】 The prediction model constructed based on the risk factors of intraoperative massive RBC infusion in TAAD patients can effectively predict the risk of intraoperative massive RBC infusion with high clinical predictive efficacy.
