OBJECTIVES: To investigate the expression of CD123 in children with acute lymphoblastic leukemia (ALL) and its effect on the clinical characteristics and prognosis of children with B-lineage acute lymphoblastic leukemia (B-ALL). METHODS: A retrospective analysis was conducted on the clinical data of 251 children with ALL who were admitted to the Department of Hematology and Oncology, Children's Hospital of Kunming Medical University, from December 2019 to June 2022. According to the expression of CD123 at initial diagnosis, the children were divided into CD123+ group and CD123- group, and the two groups were compared in terms of clinical characteristics and treatment outcome. The factors influencing the prognosis were analyzed. RESULTS: Among the 251 children with ALL, there were 146 children (58.2%) in the CD123+ group. The B-ALL group had a significantly higher positive expression rate of CD123 than the acute T lymphocyte leukemia group (P<0.05). Compared with the CD123- group, the CD123+ group had significantly lower peripheral blood leukocyte count and percentage of juvenile cells and a significantly higher proportion of children with high hyperdiploid karyotype or an age of 1-10 years, with a relatively low proportion of children with E2A-PBX1 fusion gene (P<0.05). The multivariate Cox proportional-hazards regression model analysis showed that compared with the >10 years group, the 1-10 years group had a significantly higher overall survival rate (P<0.05), and compared with the high risk group, the moderate risk group had a significantly higher event-free survival rate in children with B-ALL (P<0.05). CONCLUSIONS: CD123 is widely expressed in children with B-ALL, and positive expression of CD123 might be an indicator for good prognosis in children with B-ALL, which is of great significance for evaluating the efficacy of remission induction therapy and survival prognosis of children with B-ALL.

Sarcopenia is associated with the presence of nonalcoholic fatty liver disease in Zhejiang Province, China: a cross-sectional observational study.

BACKGROUND: Currently, both non-alcoholic fatty liver disease (NAFLD) and sarcopenia have attracted extensive attention in public health. However, the relationship between NAFLD and sarcopenia remains unclear. This study aimed to clarify the sex-specific association between sarcopenia and NAFLD according to the Asian Working Group for Sarcopenia (AWGS). METHODS: Dual-energy X-ray absorptiometry (DXA) and hepatic ultrasonography were measured in 578 participants (92 men and 486 women) during their annual health examinations. Multivariate logistic regression models were used to explore the association between NAFLD and sarcopenia with its two components. RESULTS: A total of 154 participants (30 men and 124 women) had NAFLD. The prevalence of sarcopenia was higher among the participants with NAFLD than among those without NAFLD (men: 20.0% vs. 9.7%, P = 0.295, women: 15.3% vs. 8.0%, P = 0.019). Low muscle mass (LMM) was independently associated with NAFLD in both men and women (men: odds ratio [OR], 2.88; 95% confidence interval [CI] 1.52-5.46; women: OR, 2.08; 95% CI 1.63-2.67). However, low muscle strength (LMS) was independently associated with NAFLD only in male participants, with an OR of 1.15 (95% CI 1.02-1.28). CONCLUSION: The occurrence of sarcopenia was associated with a higher risk of NAFLD, especially in men, as demonstrated by lower muscle mass and lower muscle strength.

Out-of-hospital cardiac arrest in a young adult survivor with sequelae of childhood Kawasaki disease: A case report.

BACKGROUND: Kawasaki disease (KD) is an acute type of systemic vasculitis involving small to medium-sized muscular arteries and outbreaks during childhood. KD can cause myocardial ischemia, infarction, and sudden cardiac arrest. We present a case of a young adult survivor of out-of-hospital cardiac arrest as late KD sequelae. CASE SUMMARY: A 29-year-old man with presumed acute KD history at the age of 5 suddenly lost consciousness while jogging and was diagnosed a sudden cardiac arrest by an emergency doctor. After about 10 min cardiopulmonary resuscitation, return of spontaneous circulation was achieved, and the patient was transferred to our hospital. A coronary computed tomography angiogram and coronary angiography revealed extensive calcifications of left anterior descending and right coronary artery aneurysms. The patient was an active individual who took exercise regularly and claimed no previous symptoms of chest pain or shortness of breath on exertion. The most possible cause of his sudden cardiac arrest could be presumed as a thrombus within the coronary artery aneurysms. After that, a thromboembolism induced extensive ischemia, and this ischemia-induced arrhythmia led to a cardiac arrest. CONCLUSION: Few patients who suffer a late sequela of KD can survive from out-of-hospital cardiac arrest. Medications, surgical intervention, and active follow-up are extremely important for this patient to prevent occurrence of adverse events in the future.

National prevalence of coronary heart disease and its relationship with human development index: A systematic review.

BACKGROUND: Coronary heart disease has become a major health concern over the past several decades. Several reviews have assessed the effects of socioeconomic status on the coronary heart disease epidemic in communities and countries, but only a few reviews have been performed at a global level. This study was to explore the relationship between the prevalence of coronary heart disease and socioeconomic development worldwide using the Human Development Index. DESIGN: Systematic review. METHODS: The data in this study were collected from the MEDLINE database. Cross-sectional studies reporting the prevalence of coronary heart disease until November 2014 were collected. The Human Development Index was sourced from the United Nations Development Programme Database and was used to measure the socioeconomic achievements of countries. Each country was classified as a developing or developed country based on its level of development according to the Human Development Index value. RESULTS: Based on the data analysis on the global level, coronary heart disease prevalence had no association with the national Human Development Index (rho = 0.07). However, there was a positive association between coronary heart disease prevalence and the national Human Development Index in developing countries, although a negative association existed in developed countries (rho = 0.47 and -0.34, respectively). In addition, the past decades have witnessed a growing coronary heart disease epidemic in developing countries, with reverse trends observed in developed countries (P = 0.021 and 0.002, respectively). CONCLUSIONS: With the development of socioeconomic status, as measured by the Human Development Index, the prevalence of coronary heart disease is growing in developing countries, while declining in developed countries. Future research needs to pay more attention to the reasonable allocation of medical resources and control of coronary heart disease risk factors.

The relationship between serum levels of total bilirubin and coronary plaque vulnerability.

OBJECTIVES: Previous studies have reported that serum total bilirubin provides some protection against coronary artery disease (CAD); however, the relationship between serum levels of total bilirubin and culprit/target plaque vulnerability in patients with CAD remains unclear. In this study, we investigated the association between total bilirubin and tissue characterization of coronary plaque in patients with CAD. METHODS: We enrolled 85 consecutive patients with CAD who underwent coronary angiography and intravascular ultrasound analyses [45 with acute coronary syndrome (ACS); 40 with stable angina pectoris (SAP)], and 45 age-matched participants served as the control group. Serum levels of total bilirubin in all participants were measured. The stability of the coronary plaque was compared between the ACS group and the SAP group, and the relationship between serum levels of total bilirubin and the features of coronary plaque was analyzed. RESULTS: Serum levels of total bilirubin in the ACS group were significantly lower than those in the SAP and control groups (P<0.01). Serum levels of total bilirubin were positively associated with fibrous plaques (r=0.386, P<0.001), whereas they were negatively associated with plaque burden (r=-0.413, P<0.001), lipid plaque (r=-0.419, P<0.001), and remodeling index (r=-0.275, P<0.05). Furthermore, an independent association between serum levels of total bilirubin and lipid-rich plaques (odds ratio, 0.78; 95% confidence interval, 0.64-0.95) was observed. CONCLUSION: Serum total bilirubin levels were found to be inversely associated with coronary plaque vulnerability, and decreased serum levels of total bilirubin may be an important factor for coronary lipid plaque formation, which contributes to the pathogenesis of CAD.

Systematic Review with Meta-Analysis: Alcohol Consumption and Risk of Colorectal Serrated Polyp.

BACKGROUND: Alcohol intake is closely related to colorectal cancer, which remains inconsistent with studies on the relation between alcohol consumption and risk of colorectal serrated polyp (SP) which was proven to have potential of developing into malignant serrated neoplasm. AIM: A meta-analysis investigating the association between alcohol intake and colorectal SP with the dose-response of alcohol intake was conducted. METHODS: The literature search was performed on PubMed to identify pertinent articles presenting results for at least three categories of alcohol consumption dated up to October 2014. Summarized relative risks (RRs) with 95 % confidence intervals (CIs) were estimated using random or fixed effects models based on statistical heterogeneity. RESULTS: A total of ten observational studies were identified in this meta-analysis. All drinkers were associated with 24 % increased risk of colorectal SP compared with non-/occasional drinkers. In particular, the light alcohol intake was not related to an increased risk of colorectal SP (RR 1.05, 95 % CI 0.93-1.18), whereas the RRs were 1.19 (95 % CI 1.02-1.40) for moderate alcohol intake and 1.60 (95 % CI 1.35-1.91) for heavy alcohol intake. The risks were consistent in further dose-response analysis. Meanwhile, subgroup analyses demonstrated that patients in America had more increased risk of SP with respect to those in Europe and Asia. In terms of subtype of colorectal SP, alcohol consumption had a greater influence on SSA than HP. CONCLUSIONS: This is the first meta-analysis that demonstrated the relationship between moderate and heavy alcohol consumption and increasing risks of colorectal SP.
