The incidence of delayed chemotherapy-induced nausea and vomiting is relatively high among pediatric cancer patients. Nausea and vomiting symptoms can exacerbate physical and psychological burdens, potentially leading to aversion and reduced treatment adherence. This paper analyzes and summarizes delayed chemotherapy-induced nausea and vomiting in pediatric cancer patients, covering overview, influencing factors, assessment tools, and non-pharmacological interventions, aiming to provide insights for clinical prevention and intervention strategies targeting delayed chemotherapy-induced nausea and vomiting in pediatric patients.

Diabetes is a chronic disease that requires lifelong medication and long-term management. The longer the duration of the disease, the more likely it is to lead to progressive chronic complications affecting the eyes, kidneys, nervous system, and cardiovascular system. These complications may result in gradual functional decline or even organ failure, and may also trigger severe acute metabolic disorders. The cumulative financial burden on patients and their families can be substantial, giving rise to what is known as financial toxicity, which in turn may negatively affect patients' health outcomes. This review comprehensively explores the concept of financial toxicity in diabetic patients, including its assessment tools, influencing factors, and coping strategies. It also offers targeted suggestions aimed at informing the development of more scientific and effective systemic interventions, with the ultimate goal of improving treatment outcomes and quality of life for individuals living with diabetes.

Objective:To establish a modified one-stage clotting assay (mOSA) based on the STA-R Evolution coagulation analyzer for quantifying emicizumab (EMI) concentration and to preliminarily evaluate its analytical performance; meanwhile to explore the clinical utility of the standard one-stage clotting assay (sOSA) in indirectly predicting EMI levels through surrogate factor Ⅷ (FⅧ) activity.Methods:A total of 30 pediatric patients with hemophilia A (HA) treated with EMI in the Hemophilia Treatment Center of Shenzhen Children′s Hospital from January 2023 to March 2025 were enrolled, and 48 post-treatment plasma samples were collected. EMI standards (2.5~100 μg/ml) were prepared using FⅧ-deficient plasma to establish the mOSA detection system. The linearity, accuracy, and precision of the method were evaluated. Surrogate FⅧ activity was measured by sOSA to estimate EMI concentrations, and its correlation with mOSA-derived EMI concentrations was analyzed using Spearman correlation analysis. The equivalent FⅧ activity in patient plasma samples was measured using a human chromogenic substrate assay-based FⅧ activity detection reagent, and Spearman correlation analysis was employed to evaluate its correlations with both the EMI concentrations measured by the mOSA method and estimated by the sOSA method respectively.Results:The established mOSA method for EMI detection showed excellent linearity in the range of 2.5?100 μg/ml ( Y=1.047 X?1.033, R 2=0.995, P<0.001). Average spike recovery rates at 25, 50, and 75 μg/ml were 101.55%(25.39/25.00), 105.31%(52.66/50.00), and 98.20%(73.65/75.00), respectively. Coefficients of variations of within-and inter-batch were 3.47%?4.80% and 6.30%?8.96%, respectively. A prediction model for EMI concentration was established as follows: estimated EMI concentration (μg/ml)=0.095×[alternative FⅧ activity (%) measured by sOSA]+2.652 ( R2=0.999, P<0.001). Validation demonstrated a strong correlation between the EMI concentration measured by the mOSA method and the EMI concentration estimated by the sOSA method ( r=0.989, P<0.001), with good consistency ( Y=1.014 X+0.684, R2=0.972, P<0.001). Both the EMI concentration measured by the mOSA method and the EMI concentration estimated by the sOSA method showed extremely strong correlations with the equivalent FⅧ activity ( r=0.986 and 0.987, respectively; P<0.001 for both). Conclusions:The mOSA system established on the STA-R Evolution analyzer demonstrates robust linearity, accuracy, and reproducibility, fulfilling clinical requirements for therapeutic drug monitoring of EMI. The sOSA method provides reliable indirect estimation of EMI concentrations through surrogate FⅧ activity, offering critical support for emergency decision-making.

Objective:To investigate the application value of 72-hour three-lead electrocardiogram(ECG)monitoring with adhesive patch(AP)in patients with palpitation.Methods:A retrospective analysis was performed for the medical history and ECG data of the patients who underwent 72-hour three-lead ECG monitoring with AP due to palpitation in The First Affiliated Hospital of Chongqing Medical University.The incidence rates of arrhythmia and transient ST-T changes were compared at 24 and 72 hours,as well as the rate difference between the detection rate of arrhythmia and transient ST-T changes at 72 hours and the detection rate at 24 hours in the context of various risk factors such as age,hypertension,hyperlipidemia,and coronary heart disease.Results:Among the 216 pa-tients with palpitation,the detection rates of various types of arrhythmia and transient ST-T changes at 72 hours were significantly higher than those at 24 hours(P<0.05).The rate difference of atrial premature beats in patients aged<60 years was significantly higher than that in patients aged≥60 years(P<0.01).The rate difference of atrial premature beats in hypertensive patients was lower than that in non-hypertensive patients(P<0.05).The rate difference of T-wave changes in patients without hypertension or coronary heart dis-ease was greater than that in patients with hypertension or coronary heart disease(P<0.01).Compared with 24-hour three-lead ECG monitoring,72-hour three-lead ECG monitoring with AP can significantly improve the detection rate of arrhythmia and transient ST-T changes.In patients with palpitation aged<60 years or without hypertension,72-hour three-lead ECG monitoring with AP is more sen-sitive to atrial premature beats which are consistent with self-perceived symptoms,and in patients with palpitation without hyperten-sion or coronary heart disease,72-hour three-lead ECG monitoring with AP is more sensitive to transient T-wave changes associated with symptoms.Conclusion:The technique of 72-hour three-lead ECG monitoring with AP greatly promotes the accuracy and timeli-ness of diagnosis,reduces the economic burden of patients with pal-pitations,and optimizes the allocation of medical resources.

Objective To analyze the burden of atherosclerotic cardiovascular disease(ASCVD)attributable to lifestyle and metabolic factors in China from 1990 to 2021 and predict its future trends,providing evidence for public health prevention and control.Methods Based on the Global Burden of Disease(GBD)2021 database,we extracted disability-adjusted life years(DALYs)of ASCVD attributable to 7 key risk factors:dietary,low physical activity,smoking,high body mass index(BMI),high fasting blood glucose,high low-density lipid cholesterol(LDL-C),and hypertension.Age-standardized DALY rates(ASDR)were also calculated to account for variations in age structure,and an ARIMA model was applied to predict future trends.Results ① Overall trend analysis showed the leading risk factor for ischemic heart disease(IHD)shifted from dietary risks in 1990 to hypertension in 2021,while hypertension and smoking remained the primary risk factors for ischemic stroke(IS)and peripheral artery disease(PAD),respectively.② In BRICS nations,hypertension was the dominant risk factor for both IHD and IS,whereas in China,smoking and high fasting blood glucose continued to be the major drivers of PAD burden.③ Sex-specific analysis revealed that hypertension was the leading risk factor for IHD and IS in both males and females.For PAD,smoking was the main risk factor in males,while high fasting blood glucose was for females.Age-stratified analysis revealed that in the 15-49 age group,dietary,high LDL-C and smoking were the primary factor for IHD,IS and PAD,respectively;in the 50-69 group,dietary predominated IHD risk,hypertension IS,and smoking PAD;and among those aged≥70 years,hypertension was the leading risk factor for both IHD and IS,and high fasting blood glucose was for PAD.④ ARIMA model forecasted that by 2035,DALYs for IHD,IS,and PAD will increase to 82.816 million,46.808 million,and 0.192 million person-years,respectively.Conclusion The ASCVD burden attributable to lifestyle and metabolic factors continues to rise in China from 1990 to 2021,and is projected to further increase by 2035.Countermeasures We suggest that current prevention and control priorities are enhanced management of metabolic factors,tailored interventions by sex and age,promotion of healthy lifestyles and tobacco control,and establishment of an integrated system of prevention-treatment-rehabilitation-research.

Cytidine/uridine monophosphate kinase 2(CMPK2)is an interferon-stimulated gene that plays an important role against viral infections.CMPK2 is also a rate-limiting enzyme in mitochon-dria that maintains intracellular levels of UTP/CTP and can affect inflammation triggered by path-ogenic infections and other causes of alterations in mitochondria.In this article,we review the structure and distribution of CMPK2,its role in responding to pathogenic infections and the regu-lation of inflammation,and the associated signaling pathways.
