The average amount of sleep people of all ages get has declined sharply in the past 50 years. The detrimental health effects of sleep deprivation are well documented and substantial. Even though electronic media use often takes place in the hours before sleep, the extent to which media use may interact with sleep is understudied and not well understood. Communication scholars are well positioned to contribute to this area, as a systematic, theoretical understanding of the relationship between media and sleep is still lacking. This primer charts the state of knowledge on electronic media and sleep and explores possible next steps. First, we introduce the problem of sleep deprivation and describe the basic science of sleep with relevant terminology. Then, we review the research on electronic media and sleep and offer an agenda for research.

Background: Gastrointestinal bleeding (GIB) is a common condition in the emergency department (ED) with high incidence and mortality.
Objectives: Very early risk stratification of GIB patients can sometimes be a challenge. The decision to intubate these patients is multifactorial and requires careful consideration.

Poly(lactic) (PLA) is a biodegradable material obtained from renewable resources and is recognized as a safe biopolymer by the Food and Drug Administration. PLA expresses excellent mechanical and moldability attributes nonetheless poor elasticity/functionality limits its widespread utilization. One approach to compensate for this is chemical surface modification through free radical grafting with small organic molecules like maleic anhydride (MA).

For the purpose of assessing image quality and calculating patient X-ray dosage in radiology, computed tomography (CT), fluoroscopy, mammography, and other fields, it is necessary to have prior knowledge of the X-ray energy spectrum. The main components of an X-ray tube are an electron filament, also known as the cathode, and an anode, which is often made of tungsten or rubidium and angled at a certain angle. At the point where the electrons generated by the cathode and the anode make contact, a spectrum of X-rays with energies spanning from zero to the maximum energy value of the released electrons is created.

Antimicrobial resistance (AMR) is a major global health threat, exacerbated by globalization which facilitates the spread of resistant bacteria. Addressing this issue requires a One Health perspective, involving humans, animals, and the environment. This study aims to compare the phenotypic resistance profiles of 69 clinical bacterial isolates (Enterobacteriaceae and Pseudomonaceae) from a Veterinary Teaching Hospital in Spain with their genotypic resistance profiles based on the presence of Extended-Spectrum Beta-Lactamases (ESBLs), AmpC and carbapenemases -enconding genes.
