Impact of intensive agriculture and pathogens on honeybee (Apis mellifera) colony strength in northwestern Italy.

Honeybee colony survival has significantly decreased in many countries over recent decades, which has been associated with multiple factors including pathogens, parasites, resource availability, and environmental stressors, with agricultural intensification playing a key role. This study assessed the effects of Varroa destructor mite infestation, viral prevalence and load, and agrochemical concentrations in the hive matrix on colony strength in two apiaries located in different agricultural contexts (intensive vs traditional) in Northwestern Italy from March to September 2021. The results revealed that colonies in the intensively managed area exhibited lower colony strength and higher mortality rates.

Caffeine Use in the Anesthetic Management of a Patient With Congenital Central Hypoventilation.

Congenital central hypoventilation syndrome (CCHS) is a rare neurological disease affecting the brain's response to carbon dioxide levels, resulting in dysregulation of respiration. CCHS is characterized by a diminished effort to breathe during sleep despite hypoxia and hypercapnia. Ventilation is adequate during wakeful periods but diminished during sleep.
