[Phone triage in primary care practices].

In primary care medicine for adult or pediatric populations, phone calls from patients or parents are common. The variety of questions is broad, going from simple administrative requests to life-threatening emergencies. The safety of the patient is the main priority when answering these calls.

[The challenges of pediatric emergencies in the office].

This article examines the diversity of pediatric emergencies in a medical office, shedding light on the complexity of some situations. To address emergencies that are both psychosocial and biomedical, the pediatrician must possess a variety of skills and have an in-depth understanding of the local medical network. Limited communication with young children requires the search for clues, generating uncertainty.

SARS-CoV-2 Spike Protein Induces Hemagglutination: Implications for COVID-19 Morbidities and Therapeutics and for Vaccine Adverse Effects.

Experimental findings for SARS-CoV-2 related to the glycan biochemistry of coronaviruses indicate that attachments from spike protein to glycoconjugates on the surfaces of red blood cells (RBCs), other blood cells and endothelial cells are key to the infectivity and morbidity of COVID-19. To provide further insight into these glycan attachments and their potential clinical relevance, the classic hemagglutination (HA) assay was applied using spike protein from the Wuhan, Alpha, Delta and Omicron B.1.
