Timing of intravenous dexamethasone and analgesia after brachial plexus block: a randomized, double-blind, placebo-controlled trial.

Background: The addition of intravenous dexamethasone can significantly prolong analgesia and reduce opioid-related side effects after brachial plexus blockade, but the most effective administration time is yet unknown. The objective of this study is to determine if the timing of administration of dexamethasone affects the duration of analgesia after supraclavicular brachial plexus block.

Methods: This is a double-blind, placebo-controlled, randomized trial performed at a single-center, tertiary academic health sciences center.

Serological Investigation for in Cetaceans from the Northwestern Mediterranean Sea.

Neurobrucellosis in cetaceans, caused by , is a relevant cause of death in striped dolphins () from the Mediterranean Sea. Serological tests are not used as a routinary technique for the diagnosis of this infection. We briefly describe the pathological findings of nine free-ranging stranded cetaceans diagnosed with disease or infection in our veterinary necropsy service from 2012 to 2022.

Viral shedding and environmental dispersion of two clade 2.3.4.4b H5 high pathogenicity avian influenza viruses in experimentally infected mule ducks: implications for environmental sampling.

High pathogenicity avian influenza viruses (HPAIVs) have caused major epizootics in recent years, with devastating consequences for poultry and wildlife worldwide. Domestic and wild ducks can be highly susceptible to HPAIVs, and infection leads to efficient viral replication and massive shedding (i.e.
