Objective: The study aim was to identify the frequency with which tidal volumes were achieved in a target range in infants requiring positive pressure ventilation on emergency transport.
Study Design: We performed a prospective observational study of infants requiring continued positive pressure ventilation during emergency transport after resuscitation and stabilization. Blindly recorded data were analyzed for percentage of breaths that were below range, in range, and above desired range of 4-6 mL/kg.
Result: Fourteen patients were monitored during transport from the delivery room to the neonatal intensive care unit, and 15 patients were monitored during inter-facility transport. During delivery room transport, 21 and 7% of patients were in target range greater than 50 and 90% of the time, respectively. During inter-hospital transport, 60 and 7% of patients were in target range greater than 50 and 90% of the time, respectively.
Conclusion: Clinical assessment of appropriate ventilation is difficult and often inaccurate during emergency neonatal transport. Improved monitoring of respiratory function to guide clinical status during transport is necessary. More investigation and implementation are urgently needed.

A Comprehensive Review of the Development and Therapeutic Use of Antivirals in Flavivirus Infection.
Viruses

Department of Microbiology and Immunology, Miller School of Medicine, University of Miami/UHealth, Miami, FL 33136, USA.
Flaviviruses are a diverse group of viruses primarily transmitted through hematophagous insects like mosquitoes and ticks. Significant expansion in the geographic range, prevalence, and vectors of flavivirus over the last 50 years has led to a dramatic increase in infections that can manifest as hemorrhagic fever or encephalitis, leading to prolonged morbidity and mortality. Millions of infections every year pose a serious threat to worldwide public health, encouraging scientists to develop a better understanding of the pathophysiology and immune evasion mechanisms of these viruses for vaccine development and antiviral therapy.

Cyclodextrins can serve as carriers for various payloads, utilizing their capacity to form unique host-guest inclusion complexes within their cavity and their versatile surface functionalization. Recently, cationic cyclodextrins have gained considerable attention, as they can improve drug permeability across negatively charged cell membranes and efficiently condense negatively charged nucleic acid due to electrostatic interactions. This review focuses on state-of-the-art and recent advances in the construction of cationic cyclodextrin-based delivery systems.

Background: The Epstein-Barr virus (EBV) is intricately linked to a range of human malignancies, with EBV latent membrane protein 2A (LMP2A) emerging as a potential target antigen for immunotherapeutic strategies in the treatment of nasopharyngeal carcinoma (NPC).
Methods: The modified vaccinia virus Ankara (MVA) is universally used in vector vaccine research because of its excellent safety profile and highly efficient recombinant gene expression. Here, we constructed a novel MVA-LMP2A recombinant virus and investigated its specific immune response induction and oncolytic effect.
Bias in Discontinuous Elevational Transects for Tracking Species Range Shifts.
Plants (Basel)
January 2025
College of Life Sciences, Zhejiang University, Hangzhou 310058, China.
Climate change is compelling species to seek refuge at higher elevations and latitudes. While researchers commonly study these migrations using discontinuous elevational transects, this methodology may introduce significant biases into our understanding of species movement. These potential biases could lead to flawed biodiversity conservation policies if left unexamined.
