Globally approved vaccines for COVID-19: a systematic review.

COVID-19 caused a public health emergency, which instituted a global effort to develop vaccines using different platforms, such as basic types and new-generation vaccines. Considering the importance of vaccination in preventing the severity of infectious diseases and the success in developing and approving vaccines against COVID-19 in record time, it is essential to learn about the characteristics of these vaccines. This study aimed to conduct a structured, systematic review following the PRISMA guideline, to analyze the general characteristics of vaccines approved globally for use against COVID-19.

Comprehensive histopathological analysis of gastric cancer in European and Latin America populations reveals differences in PDL1, HER2, p53 and MUC6 expression.

Introduction: Gastric cancer (GC) burden is currently evolving with regional differences associated with complex behavioural, environmental, and genetic risk factors. The LEGACy study is a Horizon 2020-funded multi-institutional research project conducted prospectively to provide comprehensive data on the tumour biological characteristics of gastroesophageal cancer from European and LATAM countries.

Material And Methods: Treatment-naïve advanced gastroesophageal adenocarcinoma patients were prospectively recruited in seven European and LATAM countries.

Nasal Irrigation With Saline Solution for Pediatric Acute Upper Respiratory Infections: A Systematic Review.

Acute upper respiratory tract infections (URTIs) are defined as infectious diseases confined anatomically to the upper respiratory tract, with a duration of up to 28 days. Treatment for URTIs in pediatrics typically involves antipyretics and decongestants and, at times, antibiotics, despite most infections being viral. Nasal irrigation with saline solution is frequently used as an adjunct treatment for URTI symptoms.

Effects of the morphology and structural cycles of Sabellaria wilsoni Lana & Gruet, 1989 (Annelida: Sabellariidae) reefs on the associated macrofauna.

Despite their ecological importance, there has been insufficient investigation of reefs constructed by polychaetes of the family Sabellariidae in tropical regions. The present study compared macrofauna associated with Amazonian Sabellaria wilsoni reefs with focus on different morphologies (platform vs. hummock reefs) during distinct annual phases of structural development (preserved, eroded, and recuperation).

Resolving the conflictive phylogenetic relationships of Oceanites (Oceanitidae: Procellariiformes) with the description of a new species.

The family Oceanitidae, formerly considered a subfamily of Hydrobatidae, includes all the small storm-petrels of the southern hemisphere. The ancestor-descendent relationships and evolutionary history of one of its genera, Oceanites, have been partially studied, yielding contrasting results. We revised the phylogenetic relationships of this group using Bayesian inference (BI) based on new sequence data of the mitochondrial gene Cytb and linear morphological measurements of all species and five subspecies-level taxa in Oceanites, including a new taxon from the Chilean Andes.
