Associations between unintentional injuries and bullying victimization in adolescents: evidence from a large-scale cross-sectional study in China.

Background: Little is known about the associations between unintentional injuries from the perspective of parents and their children's bullying victimization. This study aimed to examine the links between parent-reported unintentional injury subtypes and student-reported experiences of bullying victimization from a school-based large-scale survey.

Methods: A total of 30,386 students from 35 primary schools, 27 middle schools, and 6 high schools with available data on unintentional injuries, school bullying victimization, and covariates were included in this study.

Multifaceted determinants of depressive symptoms in children migrating back from urban to rural areas: An ecological systems theory approach.

Background: While many studies have examined mental health and influencing factors of rural Chinese children who migrated back from urban areas, holistic exploration of multifaceted determinants of their depressive symptoms is lacking; this study, drawing on Bronfenbrenner's ecological systems theory and the process-person-context-time (PPCT) model, investigated multilevel factors' impact on such symptoms and gender differences.

Methods: A cross-sectional survey was conducted in 2022 in Nanling County (Anhui Province) in China. A sample of 859 school students in grades 5-9 completed assessments measuring their depressive symptoms (using the Children's Depression Inventory, CDI) and different blocks of variables (CONTEXT, PERSON, and PROCESS).

Solar-Blind UV Organic Mechanoluminescent Materials.

Organic mechanoluminescent (ML) materials have attracted intensive attention for their potential applications in real-time stress sensing and structural damage monitoring. To avoid interference from daylight or artificial lighting sources, the ML-based sensors can be only used in dark-field scenarios, which becomes the most serious limitation for their development. Herein, we proposed a new strategy that adjusts the ML spectra to the solar-blind ultraviolet (UV) region to address this challenge.

Intrinsic Narrowband Blue Phosphorescent Materials and Their Applications in 3D Printed Self-monitoring Microfluidic Chips.

Organic room-temperature phosphorescent (RTP) materials, especially with narrowband emission properties, exhibit great potential for applications in display and sensing, but have been seldom reported. Herein, a rare example of the intrinsic narrowband blue RTP material is fabricated and reported. A series of indolo[3,2,1-kl]phenothiazine derivatives, named Cphpz, 1O-Cphpz, and 2O-Cphpz, are designed and synthesized.

Changes of the gut microbiota composition and short chain fatty acid in patients with atrial fibrillation.

Background: With the establishment of the cardiac-gut axis concept, increasing evidence has suggested the involvement and important regulatory role of the gut microbiota (GM) and short chain fatty acid (SCFA) in cardiovascular diseases. However, the relationship between GM and atrial fibrillation (AF) is still poorly understood.

Objectives: The aim of this study was to investigate whether there were differences in GM and SCFA between AF patients and healthy controls.

Recent Developments of Photodeformable Polymers: From Materials to Applications.

Photodeformable polymer materials have a far influence in the fields of flexibility and intelligence. The stimulation energy is converted into mechanical energy through molecular synergy. Among kinds of photodeformable polymer materials, liquid crystalline polymer (LCP) photodeformable materials have been a hot topic in recent years.

Highly Twisted Thermally Activated Delayed Fluorescence (TADF) Molecules and Their Applications in Organic Light-Emitting Diodes (OLEDs).

Thermally activated delayed fluorescence (TADF) materials have attracted great potential in the field of organic light-emitting diodes (OLEDs). Among thousands of TADF materials, highly twisted TADF emitters have become a hotspot in recent years. Compared with traditional TADF materials, highly twisted TADF emitters tend to show multi-channel charge-transfer characters and form rigid molecular structures.

Association of the Systemic Immune-Inflammation Index with Outcomes in Acute Coronary Syndrome Patients with Chronic Kidney Disease.

Background: The systemic immune-inflammation index (SII; neutrophil × platelet/lymphocyte) is a novel marker for immune and inflammatory status and is associated with adverse prognosis in cardiovascular disease.

Methods: In total, 744 patients diagnosed with acute coronary syndrome (ACS) and chronic kidney disease (CKD) were included in our study, received standard therapies, and were followed up. Patients were divided into high and low SII groups according to the baseline SII.

Clinical Impact of Thrombus Aspiration and Interaction With D-Dimer Levels in Patients With ST-Segment Elevation Myocardial Infarction Undergoing Primary Percutaneous Coronary Intervention.

To evaluate the effect of thrombus aspiration (TA) strategy on the outcomes and its interaction with D-dimer levels in patients with ST-segment elevation myocardial infarction (STEMI) during primary percutaneous coronary intervention (PCI) in "real-world" settings. This study included 1,295 patients with STEMI who had undergone primary PCI with or without TA between January 2013 and June 2017. Patients were first divided into a TA+PCI group and a PCI-only group, and the baseline characteristics and long-term mortality between the two groups were analyzed.

Spironolactone Improves the All-Cause Mortality and Re-Hospitalization Rates in Acute Myocardial Infarction with Chronic Kidney Disease Patients.

Mineralocorticoid receptor antagonists (MRA) improve outcomes in chronic kidney disease (CKD) and acute myocardial infarction (AMI) patients. However, the lack of evidence regarding long-term clinical outcomes in the use of MRA, including spironolactone, in patients with AMI combined with CKD. This study aimed to investigate whether spironolactone could significantly reduce the risk of all-cause mortality and re-admission in patients with AMI and CKD.

A prognostic nomogram for long-term major adverse cardiovascular events in patients with acute coronary syndrome after percutaneous coronary intervention.

Background: Accurate prediction of major adverse cardiovascular events (MACEs) is very important for the management of acute coronary syndrome (ACS) patients. We aimed to construct an effective prognostic nomogram for individualized risk estimates of MACEs for patients with ACS after percutaneous coronary intervention (PCI).

Autophagy modulates mesenchymal-to-endothelial transition via p53.

Mesenchymal-to-endothelial transition (MEndT) is one of the mechanisms that influences cardiac fibrosis, which is a key process in cardiac remodeling. It has been reported that autophagy inhibits endothelial cell transition. However, whether autophagy could modulate MEndT in cardiac fibrosis has not yet been investigated.
