ReviewTocilizumab in patients with COVID-19: which patient, time, and dose?
Tocilizumab (TCZ) is a recombinant anti-interleukin-6 monoclonal antibody which showed uprising evidence as an anti-inflammatory agent which modulates the cytokine storm in patients with COVID-19. However, proper use of the drug requires selection of the appropriate patient and timing. The two main factors which might improve patient selection are the degree of respiratory failure and systemic inflammation. ⋯ TCZ is used in a dose of 8 mg/kg which can be repeated if there was no clinical improvement. However, there are no clear criteria for judgment of the success of the first dose. Being a drug with a major effect on gross outcomes in a serious pandemic with millions of mortalities, TCZ should be meticulously investigated to reach definitive indications and number of doses to avoid drug overuse, shortage, and side effects.

Clinically relevant concentration of propofol and benzodiazepines did not affect in vitro angiogenesis.
Angiogenesis, one of regenerative medicine, is essential in the process of wound healing. The detailed effects of intravenous anesthetics and sedatives used during perioperative period have not yet been clarified. We investigated the effects of benzodiazepines and propofol on in vitro capillary tube formation. ⋯ Propofol and benzodiazepines except high-dose midazolam did not affect in vitro angiogenesis. High-dose midazolam may impair in vitro capillary tube formation due to by suppressing proliferation and migration of endothelial cells via activation of ERK.

A two-handed airway maneuver of mandibular advancement and mouth opening in the neutral neck position for immobilization of the cervical spine.
Immobilization of the cervical spine after trauma is recommended as standard care to prevent secondary injury. We tested the hypothesis that a two-handed airway maneuver, consisting of mandibular advancement and mouth opening in the neutral neck position, would minimize changes in the angle of the cervical vertebrae at the C0/4 level and tidal volume in non-obese patients under anesthesia with neuromuscular blockade. ⋯ Our study suggests that a two-handed airway maneuver of mandibular advancement and mouth opening in the neutral neck position results in only slight change in the cervical vertebral angle at the C0/4 level in non-obese patients under general anesthesia with neuromuscular blockade.
