The burden of group A (GAS) infections: The challenge continues in the twenty-first century.

is a Gram-positive bacterium, also known as Group A (GAS), that has become a significant threat to the healthcare system, infecting more than 18 million people and resulting in more than 500,000 deaths annually worldwide. GAS infection rates decreased gradually during the 20th century in Western countries, largely due to improved living conditions and access to antibiotics. However, post-COVID-19, the situation has led to a steep increase in GAS infection rates in Europe, the United States, Australia, and New Zealand, which triggers a global concern.

Assessing river discharge dynamics through relative surface water extent changes in river basins.

Surface water in rivers is vital for human society. However, our current understanding of the dynamics and drivers of river flows relies predominantly on stream gauging data, which are limited in spatial coverage and involve significant costs. Remote sensing techniques have emerged as complementary tools for monitoring river discharge, but these satellite-based methods often require complex data processing.

A faunal inventory of methane seeps on the Pacific margin of Costa Rica.

The methane seeps on the Pacific margin of Costa Rica support extensive animal diversity and offer insights into deep-sea biogeography.

Lingual Artery Identification for Ligation in Neck Dissection and Transoral Surgery for Oropharyngeal Tumors.

Objectives: Transoral robotic surgery (TORS) and transoral laser microsurgery (TOLM) plus neck dissection are viable alternatives to radiotherapy as a treatment modality in select cases of oropharyngeal squamous cell carcinoma. Many centers advocate for elective ligation of the feeding arteries at index neck dissection prior to TORS/TOLM to mitigate the risk of catastrophic perioperative hemorrhage. Although there are multiple cadaveric studies in the literature to identify the lingual artery at multiple points throughout its course, there are no studies on the intraoperative identification of the lingual artery for elective ligation prior to TORS/TOLM.
