The European Society of Cardiology (ESC) released the "2024 ESC guidelines for the management of elevated blood pressure and hypertension" on August 30, 2024. This guideline updates the 2018 "Guidelines for the management of arterial hypertension." One notable update is the introduction of the concept of "elevated blood pressure" (120-139/70-89 mm Hg). Additionally, a new systolic blood pressure target range of 120-129 mm Hg has been proposed for most patients receiving antihypertensive treatment. The guideline also includes numerous additions or revisions in areas such as non-pharmacological interventions and device-based treatments for hypertension. This article interprets the guideline's recommendations on definition and classification of elevated blood pressure and hypertension, and cardiovascular disease risk assessment, diagnosing hypertension and investigating underlying causes, preventing and treating elevated blood pressure and hypertension. We provide a comparison interpretation with the 2018 "Guidelines for the management of arterial hypertension" and the "2017 ACC/AHA guideline on the prevention, detection, evaluation, and management of high blood pressure in adults."

To guide transfusion practice in critically ill children who often need plasma and platelet transfusions, the Transfusion and Anemia Expertise Initiative-Control/Avoidance of Bleeding (TAXI-CAB) developed Recommendations and Expert Consensus for Plasma and Platelet Transfusion Practice in Critically Ill Children. This guideline addresses 53 recommendations related to plasma and platelet transfusion in critically ill children with 8 kinds of diseases, laboratory testing, selection/treatment of plasma and platelet components, and research priorities. This paper introduces the specific methods and results of the recommendation formation of the guideline.

Background Pneumoconiosis is a prevalent and severely harmful occupational disease in China. Objective To estimate disease burden and trends of different types of pneumoconiosis among Chinese males from 1992 to 2021, and to provide insights for pneumoconiosis prevention and control as well as the development of public health policies in China. Methods Based on the latest data from the Global Burden of Disease (GBD) study (2021), this study evaluated the disease burden of pneumoconiosis among Chinese males using indicators such as mortality rate and disability-adjusted life years (DALYs). Joinpoint regression model and age-period-cohort model were applied to analyze trends in the mortality rates of pneumoconiosis among Chinese males. Results From 1992 to 2021, the age-standardized DALYs rate, age-standardized years of life lost (YLLs) rate, age-standardized years lived with disability (YLDs) rate, and age-standardized mortality rate of pneumoconiosis among Chinese men all showed a downward trend, with average annual percentage changes (AAPC) of −2.63%, −2.81%, −0.87%, and −2.56%, respectively (P<0.05). Among the four types of pneumoconiosis, the disease burden of silicosis was the highest. The age-standardized mortality rates for silicosis, asbestosis, coal worker’s pneumoconiosis, and other types of pneumoconiosis had AAPC of −2.18%, −1.24%, −3.81%, and −3.21% (P<0.05), respectively. The age effects showed mortality rates for all types increased with age, particularly in silicosis and coal worker’s pneumoconiosis. The period effects showed a general decline in mortality risk, though silicosis remained significantly higher than other types. The cohort effects indicated that later birth cohorts had progressively lower mortality risks. Conclusion From 1992 to 2021, the burden of pneumoconiosis among Chinese males has shownsome alleviation; however, pneumoconiosis remains China’s most severe occupational disease. Given that males are the primary affected group in both incidence and mortality, continued attention and targeted preventive measures are essential. Effective control strategies should be tailored to address the specific characteristics of each type of pneumoconiosis.

OBJECTIVES: To explore the mediating role of sleep duration in the relationship between depression symptoms and myopia among middle school students. METHODS: This study was a cross-sectional research conducted using a stratified cluster random sampling method. A total of 1 728 middle school students were selected from two junior high schools and two senior high schools in certain urban areas and farms of the Xinjiang Production and Construction Corps. Questionnaire surveys and vision tests were conducted among the students. Spearman analysis was used to analyze the correlation between depression symptoms, sleep duration, and myopia. The Bootstrap method was employed to investigate the mediating effect of sleep duration between depression symptoms and myopia. RESULTS: The prevalence of myopia in the overall population was 74.02% (1 279/1 728), with an average sleep duration of (7.6±1.0) hours. The rate of insufficient sleep was 83.62% (1 445/1 728), and the proportion of students exhibiting depression symptoms was 25.29% (437/1 728). Correlation analysis showed significant negative correlations between visual acuity in both eyes and sleep duration with depressive emotions as measured by the Center for Epidemiologic Studies Depression Scale (with correlation coefficients of -0.064, -0.084, and -0.199 respectively; P<0.01), as well as with somatic symptoms and activities (with correlation coefficients of -0.104, -0.124, and -0.233 respectively; P<0.01) and interpersonal relationships (with correlation coefficients of -0.052, -0.059, and -0.071 respectively; P<0.05). The correlation coefficients for left and right eye visual acuity and sleep duration were 0.206 and 0.211 respectively (P<0.001). Sleep duration exhibited a mediating effect between depression symptoms and myopia (indirect effect=0.056, 95%CI: 0.029-0.088), with the mediating effect value for females (indirect effect=0.066, 95%CI: 0.024-0.119) being higher than that for males (indirect effect=0.042, 95%CI: 0.011-0.081). CONCLUSIONS Sleep duration serves as a partial mediator between depression symptoms and myopia in middle school students.

Based on systematic review and consensus meetings of international multidisciplinary experts, the Transfusion and Anemia Expert Initiative—Control/Avoidance of Bleeding (TAXI-CAB) project team developed management strategies for platelet and plasma transfusion in critically ill children. This consensus presents five expert consensus statements and two recommendations addressing two key questions: 1) What Laboratory Tests and Physiologic Triggers Should Guide the Decision to Administer a Platelet or Plasma Transfusion in Critically ill Children? 2) What Product Attributes Are Optimal to Guide Specific Product Selection? This consensus provides guidance for decision-making regarding plasma and platelet transfusion in critically ill children in two aspects: relevant laboratory testing indicators and additional special properties of blood components. This article explains the rationale behind the recommendations in this part of the guideline, aiming to emphasize the need for clinicians to develop transfusion strategies based on multidimensional assessment, while calling for enhanced interdisciplinary collaboration and evidence-based research to optimize blood management in critically ill children, reducing the risk of over-transfusion and improving treatment outcomes. Furthermore, there remains an urgent need for further research to explore laboratory indicators associated with bleeding risk to guide transfusion therapy.

Objective To investigate the incidence rate,clinical characteristics,and prognosis of neonatal stroke in Shenzhen,China.Methods Led by Shenzhen Children's Hospital,the Shenzhen Neonatal Data Collaboration Network organized 21 institutions to collect 36 cases of neonatal stroke from January 2020 to December 2022.The incidence,clinical characteristics,treatment,and prognosis of neonatal stroke in Shenzhen were analyzed.Results The incidence rate of neonatal stroke in 21 hospitals from 2020 to 2022 was 1/15 137,1/6 060,and 1/7 704,respectively.Ischemic stroke accounted for 75％(27/36);boys accounted for 64％(23/36).Among the 36 neonates,31(86％)had disease onset within 3 days after birth,and 19(53％)had convulsion as the initial presentation.Cerebral MRI showed that 22 neonates(61％)had left cerebral infarction and 13(36％)had basal ganglia infarction.Magnetic resonance angiography was performed for 12 neonates,among whom 9(75％)had involvement of the middle cerebral artery.Electroencephalography was performed for 29 neonates,with sharp waves in 21 neonates(72％)and seizures in 10 neonates(34％).Symptomatic/supportive treatment varied across different hospitals.Neonatal Behavioral Neurological Assessment was performed for 12 neonates(33％,12/36),with a mean score of(32±4)points.The prognosis of 27 neonates was followed up to around 12 months of age,with 44％(12/27)of the neonates having a good prognosis.Conclusions Ischemic stroke is the main type of neonatal stroke,often with convulsions as the initial presentation,involvement of the middle cerebral artery,sharp waves on electroencephalography,and a relatively low neurodevelopment score.Symptomatic/supportive treatment is the main treatment method,and some neonates tend to have a poor prognosis.

Objective To investigate the risk factors for bronchopulmonary dysplasia(BPD)in twin preterm infants with a gestational age of<34 weeks,and to provide a basis for early identification of BPD in twin preterm infants in clinical practice.Methods A retrospective analysis was performed for the twin preterm infants with a gestational age of<34 weeks who were admitted to 22 hospitals nationwide from January 2018 to December 2020.According to their conditions,they were divided into group A(both twins had BPD),group B(only one twin had BPD),and group C(neither twin had BPD).The risk factors for BPD in twin preterm infants were analyzed.Further analysis was conducted on group B to investigate the postnatal risk factors for BPD within twins.Results A total of 904 pairs of twins with a gestational age of<34 weeks were included in this study.The multivariate logistic regression analysis showed that compared with group C,birth weight discordance of>25%between the twins was an independent risk factor for BPD in one of the twins(OR=3.370,95%CI:1.500-7.568,P<0.05),and high gestational age at birth was a protective factor against BPD(P<0.05).The conditional logistic regression analysis of group B showed that small-for-gestational-age(SGA)birth was an independent risk factor for BPD in individual twins(OR=5.017,95%CI:1.040-24.190,P<0.05).Conclusions The development of BPD in twin preterm infants is associated with gestational age,birth weight discordance between the twins,and SGA birth.

Objective To investigate the clinical characteristics of Ureaplasma urealyticum(UU)infection and colonization in extremely preterm infants and its impact on the incidence of bronchopulmonary dysplasia(BPD).Methods A retrospective analysis was conducted on 258 extremely preterm infants who were admitted to the Department of Neonatology,Shenzhen Maternity and Child Healthcare Hospital,from September 2018 to September 2022.According to the results of UU nucleic acid testing and the evaluation criteria for UU infection and colonization,the subjects were divided into three groups:UU-negative group(155 infants),UU infection group(70 infants),and UU colonization group(33 infants).The three groups were compared in terms of general information and primary and secondary clinical outcomes.Results Compared with the UU-negative group,the UU infection group had significant increases in the incidence rate of BPD,total oxygen supply time,and the length of hospital stay(P<0.05),while there were no significant differences in the incidence rates of BPD and moderate/severe BPD between the UU colonization group and the UU-negative group(P>0.05).Conclusions The impact of UU on the incidence of BPD in extremely preterm infants is associated with the pathogenic state of UU(i.e.,infection or colonization),and there are significant increases in the incidence rate of BPD,total oxygen supply time,and the length of hospital stay in extremely preterm infants with UU infection.UU colonization is not associated with the incidence of BPD and moderate/severe BPD in extremely preterm infants.

Objective:Hepatic fibrosis is a common pathological basis for many chronic liver diseases and can progress to cirrhosis,a leading cause of mortality in liver diseases.Early identification and reversal of hepatic fibrosis are key in the treatment of chronic liver disease.This study aims to compare the expression levels of serum core fucosylated low molecular weight kininogen(LMWK-Fc)and alpha-galactosylated(α-Gal)antibodies in patients with hepatic fibrosis at different stages,and to evaluate their diagnostic efficacy for hepatic fibrosis. Methods:A retrospective analysis was conducted on 275 patients with chronic liver disease who visited the Department of Infectious Diseases at the Second Xiangya Hospital of Central South University between June 2022 and March 2023.Among these,115 patients underwent liver biopsy.Based on the extent of collagen deposition and its impact on liver structure and microcirculation,patients were staged from 0 to 4:S0(no significant collagen deposition in liver tissues;liver structure and microcirculation are normal),S1(mild collagen deposition in liver tissues,with partial disruption of lobule structure,but microcirculation remains largely normal),S2(moderate collagen deposition in liver tissues,with partial disruption of lobule structure and microcirculation),S3(extensive collagen deposition in liver tissues,with substantial disruption of lobule structure and microcirculation),and S4(development of cirrhosis,with heavy collagen deposition,complete disruption of lobule structure,and severe impairment of microcirculation).Patients were grouped as no fibrosis(S0),fibrosis(S1-S2),and significant fibrosis(S3-S4).For the 160 patients without liver biopsy,they were categorized based on liver stiffness measurement(LSM)value:no fibrosis(F0:LSM＜7.3 kPa),fibrosis(F1-F2:LSM 7.3-12.4 kPa),and significant fibrosis(F3-F4:LSM＞12.4 kPa).Demographic data(age,gender)and laboratory indicators(alanine transaminase,aspartate transaminase,gamma-glutamyl transferase,alkaline phosphatase,alpha-fetoprotein,platelet count)were collected to calculate the fibrosis-4 index(FIB-4)and aspartate aminotransferase-to-platelet ratio index(APRI).Serum LMWK-Fc and α-Gal antibodies were measured and compared across the groups,and their correlation with fibrosis severity was analyzed.The receiver operating characteristic(ROC)curve was used to assess the predictive value of serum LMWK-Fc and α-Gal antibody levels for hepatic fibrosis. Results:Among the 160 patients without complete liver biopsy,serum α-Gal antibody and LMWK-Fc levels increased progressively from the no fibrosis group to the significant fibrosis group,with statistically significant differences(P＜0.05).Among the 115 patients with liver biopsy,serum LMWK-Fc levels were significantly higher in the fibrosis group and the significant fibrosis groups compared with the no fibrosis group,and α-Gal antibody levels were significantly higher in the significant fibrosis group compared with the no fibrosis group and the fibrosis group(P＜0.001,P=0.032,respectively).Univariate and multivariate linear regression analyses showed that hepatic fibrosis was correlated with gender and LMWK-Fc levels(both P＜0.05),but not with age,α-Gal antibody levels,FIB-4,or APRI(all P＞0.05). Conclusion:The expression levels of serum LMWK-Fc and α-Gal antibodies vary across different stages of hepatic fibrosis,suggesting a potential association with fibrosis progression.LMWK-Fc levels have a certain predictive value for the diagnosis of hepatic fibrosis.
