Creación de un sistema de vigilancia para las prácticas odontológicas de la Facultad de Odontología de la UEES

Los sistemas de vigilancia permiten monitorear, evaluar y orientar los servicios de salud hacia el logro de la calidad. En este sentido, la facultad de Odontología UEES creó un sistema para medir el rendimiento estudiantil y el cumplimiento de los programas de estudio para las prácticas odontológicas del Doctorado en Cirugía Dental a ejecutarse en 4 fases. Las variables a vigilar fueron el grado de cumplimiento de las horas de práctica para cada nivel de la clínica y los tratamientos validos por asignatura realizados en paciente con los que se obtienen las horas requerida

Risk factors associated with adverse fetal outcomes in pregnancies affected by Coronavirus disease 2019 (COVID-19): a secondary analysis of the WAPM study on COVID-19.

Objectives To evaluate the strength of association between maternal and pregnancy characteristics and the risk of adverse perinatal outcomes in pregnancies with laboratory confirmed COVID-19. Methods Secondary analysis of a multinational, cohort study on all consecutive pregnant women with laboratory-confirmed COVID-19 from February 1, 2020 to April 30, 2020 from 73 centers from 22 different countries. A confirmed case of COVID-19 was defined as a positive result on real-time reverse-transcriptase-polymerase-chain-reaction (RT-PCR) assay of nasal and pharyngeal swab specimens. The primary outcome was a composite adverse fetal outcome, defined as the presence of either abortion (pregnancy loss before 22 weeks of gestations), stillbirth (intrauterine fetal death after 22 weeks of gestation), neonatal death (death of a live-born infant within the first 28 days of life), and perinatal death (either stillbirth or neonatal death). Logistic regression analysis was performed to evaluate parameters independently associated with the primary outcome. Logistic regression was reported as odds ratio (OR) with 95% confidence interval (CI). Results Mean gestational age at diagnosis was 30.6+/-9.5 weeks, with 8.0% of women being diagnosed in the first, 22.2% in the second and 69.8% in the third trimester of pregnancy. There were six miscarriage (2.3%), six intrauterine device (IUD) (2.3) and 5 (2.0%) neonatal deaths, with an overall rate of perinatal death of 4.2% (11/265), thus resulting into 17 cases experiencing and 226 not experiencing composite adverse fetal outcome. Neither stillbirths nor neonatal deaths had congenital anomalies found at antenatal or postnatal evaluation. Furthermore, none of the cases experiencing IUD had signs of impending demise at arterial or venous Doppler. Neonatal deaths were all considered as prematurity-related adverse events. Of the 250 live-born neonates, one (0.4%) was found positive at RT-PCR pharyngeal swabs performed after delivery. The mother was tested positive during the third trimester of pregnancy. The newborn was asymptomatic and had negative RT-PCR test after 14 days of life. At logistic regression analysis, gestational age at diagnosis (OR: 0.85, 95% CI 0.8-0.9 per week increase; pPeer reviewe

In situ histochemical localization of alkaloids in leaves and pods of Prosopis ruscifolia

The tree Prosopis ruscifolia produces indolizidine alkaloids which function in plant defense as antimicrobials. Here, we propose the use of Drangendorff´s reagent, picric acid and lugol for the in situ histochemical localization of indolizidine alkaloids in the leaf parts (petiole, rachis and leaflet) and pods of P. ruscifolia. The main surface and internal anatomical features of the aerial plant parts were visualized with cresyl violet and astra blue safranin. Extracts from leaflets and pods were separated by TLC and revealed with the Dragendorff´s reagent, picric acid and lugol. Fresh cross sections of leaflets, petioles, rachis and pods were also stained with these chromogenic reagents. Glandular trichomes were absent from the surface of mature leaflets, petioles, rachis and pods. Large idioblasts were distributed in the palisade mesophylls of the leaflets and the cortical and medullar parenchyma of the petiole and the rachis. TLC of the extracts revealed with Dragendorff´s reagent, picric acid and lugol gave orange, yellow and light brown spots for the indolizidine alkaloids, respectively. Spraying with picric acid also revealed some non-alkaloid constituents. The three chromogenic reagents indicated the presence of indolizidine alkaloids in the large idioblasts of the leaflets, petioles, rachis and pods. Dragendorff´s reagent and picric acid also showed the alkaloids in the cuticles of all leaf parts and pods. The first was the most sensitive towards alkaloids and the only one that visualizes them in the phloem of the petioles and pods. The indolizidine alkaloids of P. ruscifolia seemed to be transported from green tissues to the pods, and should exert their protective function after the breakdown of leaves and pods.Fil: Gómez, Analia de Los Angeles.
