Fibrina rica en plaquetas y su aplicación en periodoncia: revisión de literatura

La fibrina rica en plaquetas (FRP) es un concentrado plaquetario de segunda generación que nos brinda, en un coágulo o membrana, gran cantidad de factores de crecimiento, leucocitos y citoquinas que se obtienen mediante la centrifugación de sangre autógena. Su fácil preparación y manipulación a diferencia de otros preparados plaquetarios hacen que pueda ser usada en la práctica clínica diaria. La presente revisión bibliográfica tiene como objetivo describir las propiedades biológicas y las aplicaciones clínicas de la FRP en la cirugía mucogingival (cobertura radicular) y en el levantamiento del piso del seno maxilar.Platelet rich fibrin (PRF) is a second generation platelet concentrate that delivers, to the clot or membrane, a high concentration of growth factors, leucocytes and cytokines that are obtained through a centrifugation from an autogenous blood sample. The easy preparation and manipulation, in comparison with other platelet preparations, allows using it in the daily clinical practice. This literature review aims to describe the biological properties and the clinical applications of the PRF in muco-gingival surgical procedures and in the maxillary sinus elevation surgery

Effects of hospital facilities on patient outcomes after cancer surgery: an international, prospective, observational study

This is an Open Access article under the CC BY 4.0 licenseBackground: Early death after cancer surgery is higher in low-income and middle-income countries (LMICs) compared with in high-income countries, yet the impact of facility characteristics on early postoperative outcomes is unknown. The aim of this study was to examine the association between hospital infrastructure, resource availability, and processes on early outcomes after cancer surgery worldwide. Methods: A multimethods analysis was performed as part of the GlobalSurg 3 study—a multicentre, international, prospective cohort study of patients who had surgery for breast, colorectal, or gastric cancer. The primary outcomes were 30-day mortality and 30-day major complication rates. Potentially beneficial hospital facilities were identified by variable selection to select those associated with 30-day mortality. Adjusted outcomes were determined using generalised estimating equations to account for patient characteristics and country-income group, with population stratification by hospital. Findings: Between April 1, 2018, and April 23, 2019, facility-level data were collected for 9685 patients across 238 hospitals in 66 countries (91 hospitals in 20 high-income countries; 57 hospitals in 19 upper-middle-income countries; and 90 hospitals in 27 low-income to lower-middle-income countries). The availability of five hospital facilities was inversely associated with mortality: ultrasound, CT scanner, critical care unit, opioid analgesia, and oncologist. After adjustment for case-mix and country income group, hospitals with three or fewer of these facilities (62 hospitals, 1294 patients) had higher mortality compared with those with four or five (adjusted odds ratio [OR] 3·85 [95% CI 2·58–5·75]; p<0·0001), with excess mortality predominantly explained by a limited capacity to rescue following the development of major complications (63·0% vs 82·7%; OR 0·35 [0·23–0·53]; p<0·0001). Across LMICs, improvements in hospital facilities would prevent one to three deaths for every 100 patients undergoing surgery for cancer. Interpretation: Hospitals with higher levels of infrastructure and resources have better outcomes after cancer surgery, independent of country income. Without urgent strengthening of hospital infrastructure and resources, the reductions in cancer-associated mortality associated with improved access will not be realised.
