The Routes of Administration for Acute Postoperative Pain Medication
No full textEffective treatment of postoperative acute pain, together with early mobilization and nutrition, is one of the perioperative strategies advocated to improve surgical outcome and reduce the costs of hospitalization. Moreover, adequate pain control reduces perioperative morbidity related to surgical stress and can also prevent the incidence of chronic postoperative pain syndromes, whose treatment is still a challenge. The choice of the most appropriate analgesics depends not only on the drug class, but also on the most suitable route of administration, the best dosage for that route, and unique limitations and contraindications for every patient. In the present review, a comprehensive analysis was performed on the different routes of administration of acute postoperative pain medications and their indications and limitations, focusing on recent evidence and international recommendations

Quasiparticle and excitonic properties of monolayer SrTiO3
No full textSrTiO3 is one of the most studied transition metal oxides. Recently, a breakthrough was achieved with the
fabrication of freestanding SrTiO3 ultrathin films down to the monolayer limit. However, the many-body effects
on the quasiparticle and optical properties of monolayer SrTiO3 remain unexplored. Using state-of-the-art many-
body perturbation theory in the GW approximation combined with the Bethe-Salpeter equation, we study the
quasiparticle band structure, optical, and excitonic properties of monolayer SrTiO 3 . We show that quasiparticle
corrections significantly alter the band-structure topology; however, the widely used diagonal G 0 W0 approach
yields unphysical band dispersions. The correct band dispersions are restored only by taking into account the
off-diagonal elements of the self-energy. The optical properties are studied both in the optical limit and for finite
momenta by computing the electron energy loss spectra. We find that the imaginary part of two-dimensional
polarizability at the long wavelength limit is dominated by three strongly bound excitonic peaks and the direct
optical gap is associated to a bright exciton state with a large binding energy of 0.93 eV. We discuss the character
of the excitonic peaks via the contributing interband transitions and reveal that the lowest bound excitonic state
becomes dark for finite momenta along -M, while the other two excitonic peaks disperse to higher energies and
eventually merge for momenta close to M
