In recent years, with the innovation and continuous development of additive manufacturing technology, research on wire arc additive manufacturing technology (WAAM) has become increasingly common and in-depth in the chemical industry, mold manufacturing, and other fields. Therefore, it has attracted the attention of many universities, research institutes, and aerospace industries, conducted in-depth research on WAAM technology, and achieved certain research results. This paper briefly summarizes the current research status of arc additive manufacturing technology and summarizes the application status of WAAM technology in product development, personalized customization, traditional process replacement, "material-structure-function" integration, mold repair, etc.

Background: Over the past three decades, male infertility has become a significant burden on global public health. As an international organization with nearly half of the world's population, BRICS plays a crucial role in global health. This study investigates the trend of male infertility burden in BRICS countries from 1990 to 2021, providing valuable information for prevention and treatment strategies.

Background: The increasing epidemiological trend of pediatric urolithiasis over the past three decades has brought it to the forefront of public health attention. An analysis of the disease burden in Brazil, Russia, India, China, and South Africa (BRICS) countries, which share common characteristics such as large population base and limited public health resources, will provide an important reference for global public health policy development. Therefore, this study aimed to investigate the trend of the prevalence of pediatric urolithiasis in BRICS countries during 1990-2021, which in turn will provide more valuable information for them and the world in the prevention and treatment of pediatric urolithiasis.

Background: Urolithiasis is a common disease of the urinary tract, the global prevalence of which is increasing year by year and which, due to its high rate of recurrence and complications, represents a major burden on the quality of life of patients and on the global public health system. As the most populous country in the world, the epidemiology of urolithiasis in China is of great importance. However, the current systematic epidemiological assessment of urolithiasis in China is relatively limited.

Background: Currently, male infertility represents a serious disease burden worldwide, and China is one of the most affected countries. The aim of this study was to examine the evolution of the disease burden of male infertility in China during the period 1990-2021 and to project the trend for 2022-2036.

Methods: By screening and processing data from the Global Burden of Disease 2021, this study obtained data on the prevalence, disability-adjusted life years and corresponding rates and age-standardised rates of male infertility between 1990 and 2021.

Objectives: Acute kidney injury (AKI) is prevalent in patients hospitalized with ST segment elevation myocardial infarction (STEMI) and is correlated with worse cardiovascular outcomes. Hypomagnesemia has been found to be associated with an elevated risk of AKI in various patient populations. Nonetheless, the relationship between hypomagnesemia and AKI incidence in patients with STEMI has not been fully elucidated.

Identifying the predictors of acute kidney injury (AKI) in patients with acute ST-segment elevation myocardial infarction (STEMI) undergoing primary percutaneous coronary intervention (PPCI) remains important. We aimed to investigate the predictive value of D-dimer levels for the incidence of AKI in such a population, with particular attention paid to sex differences. A total of 2668 patients with STEMI who underwent PPCI were retrospectively included in this study and divided into quartiles according to their plasma D-dimer levels upon admission (Q1: < 0.

Background And Aims: Hyperuricemia is a known risk factor for cardiovascular diseases, but little is known on whether the association between hyperuricemia and poor outcomes in ST-segment elevation myocardial infarction (STEMI) is modified by low-density lipoprotein cholesterol (LDL-c). This study aimed to investigate the effect of the interaction between hyperuricemia and LDL-c on the risk of 1-year post-discharge all-cause mortality in STEMI patients.

Methods And Results: A total of 1396 STEMI patients were included.

Background Patients with left ventricular thrombus (LVT) resolution can have LVT recurrence and risk for thromboembolism. However, these outcomes after LVT resolution are not well known. We aimed to assess the prevalence, risk factors, and clinical outcomes for LVT recurrence in patients with LVT resolution to inform follow-up and treatment.

Background: Hyperlactatemia is a prognostic marker among patients with ST-segment elevation acute myocardial infarction (STEMI). However, the predictive value of lactate and the dynamic change associated with acute kidney injury (AKI) among patients with STEMI, remain poorly understood. We aimed to compare single lactate values at admission (Lac) and 12 h after admission (Lac) with lactate clearance (LC) 12 h after admission for AKI prediction in patients with STEMI.

Background And Objective: Acute kidney injury (AKI) is a common complication associated with adverse outcomes among patients with ST-segment elevation myocardial infarction (STEMI). This is conflicting information about the relationship between hyperuricemia and AKI in STEMI. This work aimed to investigate the effect of the interaction between hyperuricemia and lactate on the risk of AKI.

Background: Adequate procedural anticoagulation is crucial for radial artery occlusion (RAO) prevention in patients undergoing transradial access coronary catheterization, although the effect of postprocedural anticoagulation lack thorough investigation. The aim of this study was to evaluate the clinical value of short-term postoperative anticoagulation with rivaroxaban for 24 hours and 1-month RAO prevention in patients who received transradial coronary procedures.

Methods: A total of 382 patients were randomized to receive either placebo (control group) or rivaroxaban 10 mg once daily for a period of 7 days (rivaroxaban group) to evaluate the effect of the rivaroxaban in the prevention of 24 hours and 1-month RAO assessed by Doppler ultrasound.

To evaluate the effects of occurrence and timing of sudden cardiac arrest (SCA) on survival in patients with acute myocardial infarction (AMI) who underwent emergency percutaneous coronary intervention (PCI). We analyzed 1,956 consecutive patients with AMI with emergency PCI from 2014 to 2018. Patients with cardiac arrest events were identified, and their medical records were reviewed.
