Objective: Driving under the influence (DUI) of alcohol is a major risk factor for fatal road traffic injuries (RTIs) worldwide. This study aimed to investigate the relationship between the implementation of new acts on DUI of alcohol and the clinical outcomes of patients with severe RTIs in Korea.
Methods: This is a community-based cross-sectional study using a nationwide severe trauma registry in Korea. In 2018, 2 acts with the Yoon Chang-Ho Act (Yoon's Act) were passed to strengthen the punishment for drunk driving fatal RTIs (first Yoon's act) and lower the blood alcohol concentration limit to restrict driver's licenses (second Yoon's act). The first Yoon's act was implemented on December 18, 2018, and the second Yoon's act was implemented on June 25, 2019. The study periods were categorized as pre-Act-1, pre-Act-2, Act-1, and Act-2 according to the application of Yoon's Act, and the study outcome was in-hospital mortality. Multivariable logistic regression analysis was conducted to estimate the relationship of the new acts and in-hospital mortality.
Results: Among a total of 20,376 patients with severe RTIs and 7,928 patients (drivers) with RTIs (hereafter drivers), the in-hospital mortality rates were 20.8% and 17.0%, and alcohol-related RTIs accounted for 9.7% and 8.1%, respectively. Severe RTIs tended to increase with each period (25.5 cases/day, 24.5 cases/day, 26.8 cases/day, and 30.4 cases/day, for trend <.01). In-hospital mortality significantly decreased during the Act-2 period compared to the pre-Act-2 period for all patients with severe RTIs (adjusted odds ratio = 0.54, 95% confidence interval 0.43-0.67) and drivers with RTIs (adjusted odds ratio = 0.50, 95% confidence interval 0.34-0.73).
Conclusions: Implementation of the new acts on DUI of alcohol was associated with lower odds for in-hospital mortality for patients with severe RTIs. Further studies are needed to evaluate the long-term impact of the new acts on reducing alcohol-related RTIs.

Introduction: With the worldwide growing burden of respiratory tract infections (RTIs), innovative therapeutic approaches are in high demand. Inhaled antibodies (Abs) represent a promising avenue, offering targeted treatment options with potentially better therapeutic index compared to traditional delivery methods.
Areas Covered: This comprehensive review summarizes the challenges faced in delivering Abs by (intranasal and pulmonary) inhalation.

Aim: To extend the findings of a previous clinical trial suggesting combined abacavir (ABC), lamivudine (3TC), and zidovudine (AZT) reduces type I interferon (IFN) signalling in Aicardi-Goutières syndrome (AGS).
Method: This was an open label, non-placebo-controlled phase II clinical trial (NCT04731103) in patients less than 16 years with any of five AGS genotypes. The effect of ABC or 3TC individually, or of combined ABC + 3TC + AZT, on IFN-stimulated gene (ISG) expression (primary outcome) and IFN-alpha protein (secondary outcome) in blood was assessed.

Background: Preterm infants discharged from the neonatal intensive care unit (NICU) have a risk of severe viral respiratory tract infections (RTIs). Researchers have recently reported the potential use of postbiotics to decrease RTIs in young children. However, the safety and efficacy of postbiotics for preventing RTIs in preterm infants is not yet established.

Article Synopsis
- Road traffic injuries (RTIs) are the top cause of death in kids and teens, and this study examines the differences in severity based on the type of road users—passengers, pedestrians, motorcyclists, and bicyclists.
- A large analysis of 78,021 RTI cases from emergency departments in South Korea revealed that motorcyclists had the worst outcomes in terms of serious injuries and fatalities.
- The study emphasizes the importance of using safety devices for preventing severe RTIs, particularly in passengers and motorcyclists, suggesting that tailored interventions are necessary to address the unique needs of each road user group.
