Seroprevalence, incidence estimates, and environmental risk factors for dengue, chikungunya, and Zika infection amongst children living in informal urban settlements in Indonesia and Fiji.

Background: The burden of -transmitted viruses such as dengue, chikungunya, and Zika are increasing globally, fueled by urbanization and climate change, with some of the highest current rates of transmission in Asia. Local factors in the built environment have the potential to exacerbate or mitigate transmission.

Methods: In 24 informal urban settlements in Makassar, Indonesia and Suva, Fiji, we tested children under 5 years old for evidence of prior infection with dengue, chikungunya, and Zika viruses by IgG serology.

The influence of musical experience on laparoscopic surgical skill performance: an original investigation and literature review.

Background: As the needs and curricula of surgical residencies evolve, recent studies have focused on identifying factors that may be related to faster and more efficient surgical skill acquisition, such as experience with playing video games, sports, and other dexterous activities. The aim of this study was to elucidate the relationship between instrumental musical experience and laparoscopic surgical skill performance as well as to provide an overview of the available literature on this topic.

Methods: A query from database inception to January 2023 of the PubMed database for literature discussing the association of musical experience and surgical skills was conducted.

Exploring Osteoarthritis Dynamics: Patient-Specific Cartilage Samples in an Organ-on-a-Chip Model.

Objective: This study aims to tackle the existing challenges associated with the prediction and optimization of pharmaceutical interventions for osteoarthritis (OA). The primary objective is to develop an innovative tool that provides objective and patient-specific information regarding the most affected tissue in OA, articular cartilage.

Design: We employed an organ-on-a-chip (OoC) approach to replicate the 3D structure of cartilage in an setup.

Development of a trash classification system to map potential Aedes aegypti breeding grounds using unmanned aerial vehicle imaging.

Aedes aegypti mosquitos are the primary vector for dengue, chikungunya, and Zika viruses and tend to breed in small containers of water, with a propensity to breed in small piles of trash and abandoned tires. This study piloted the use of aerial imaging to map and classify potential Ae. aegypti breeding sites with a specific focus on trash, including discarded tires.

Circulating Nucleated Red Blood Cells: An Updated Reference Interval.

Context.—: Nucleated red blood cells (nRBCs) are not identified in the peripheral blood in healthy individuals beyond the neonatal period. Their presence in children and adults is traditionally considered pathologic.
