AI Article Synopsis
- The study examined mass casualty incidents involving high-speed passenger ferries in Hong Kong from 2005 to 2015, focusing on victim arrival patterns in emergency departments.
- It found that seriously injured victims (Injury Severity Score ≥ 9) arrived at emergency departments faster than those with minor injuries, influenced by factors such as evacuation methods and distance to medical facilities.
- The research concluded that the expected dual-wave phenomenon (initial minor injuries followed by severe cases) did not occur, emphasizing the importance of effective communication for timely resource allocation in emergencies.
Article Abstract
Objective: Mass Casualty Incidents (MCIs) involving high-speed passenger ferries (HSPFs) may result in the dual-wave phenomenon, in which the emergency department (ED) is overwhelmed by an initial wave of minor injuries, followed by a second wave of more seriously injured victims. This study aimed to characterize the time pattern of ED presentation of victims in such accidents in Hong Kong.
Methods: All HSPF MCIs from 2005 to 2015 were reviewed retrospectively, with the time interval from accident to ED registration determined for each victim. Multivariable linear regression was used to identify independent factors associated with the time of ED presentation after the accidents.
Results: Eight MCIs involving 492 victims were identified. Victims with an Injury Severity Score (ISS) ≥ 9 had a significantly shorter median time interval compared to those with minor injuries. An ISS ≥ 9 and evacuation by emergency service vessels were associated with a shorter delay in ED arrival, whereas ship sinking, accident at nighttime, and a longer linear distance between the accident and receiving ED were associated with a longer delay.
Conclusion: The dual-wave phenomenon was not present in HSPF MCIs. Early communication is the key to ensure early resource mobilisation and a well-timed response.

Systematic research is still lacking on the content of hydrophilic compounds in Fu Brick Tea (FBT) from major Chinese production regions and their variation patterns during the processing of FBT. This study utilized optimized non-targeted (UHPLC-Q-Exactive Orbitrap-MS) and targeted (UHPLC-QqQ-MS) metabolomics to analyze 73 FBT samples from six regions of China and 30 samples from different stages of FBT processing. 573 and 74 hydrophilic compounds were respectively relatively and absolutely quantified for the first time.

Control of cell proliferation is critical for the lymphocyte life cycle. However, little is known about how stage-specific alterations in cell cycle behavior drive proliferation dynamics during T cell development. Here, we employed in vivo dual-nucleoside pulse labeling combined with the determination of DNA replication over time as well as fluorescent ubiquitination-based cell cycle indicator mice to establish a quantitative high-resolution map of cell cycle kinetics of thymocytes.

Behavioral and mental health (BMH) issues are increasing in adolescents as shortages of primary care and BMH providers are also rising. The healthcare burden has fallen especially hard on primary care providers (PCPs), who are showing increasing signs of burnout and making plans to reduce their work hours or leave the profession altogether. These factors impede their ability to be the first line of defense in providing emotional support to children and families.

Neonates with congenital heart disease (CHD) who undergo cardiopulmonary bypass (CPB) are at high-risk for unfavorable neurodevelopmental (ND) outcomes and are recommended for ND evaluation (NDE); however, poor rates have been reported. We aimed to identify risk factors associated with lack of NDE. This single-center retrospective observational study included neonates < 30 days old who underwent CPB and survived to discharge between 2012 and 2018.
