Training for the surgical management of postpartum hemorrhage: a multicenter survey of resident physicians.

Background: To actively address maternal morbidity and mortality in Mexico, proficiency among obstetrics and gynecology (OBGYN) residents in the surgical management of postpartum hemorrhage (PPH) is a priority. However, the capacity of programs to provide this training is unknown.

Objective: The self-reported knowledge, education, and proficiency of common surgical techniques for the management of PPH among OBGYN residents in Mexico was evaluated.

Determination of sialic acid in saliva by means of surface-enhanced Raman spectroscopy as a marker in adnexal mass patients: ovarian cancer vs benign cases.

Background: To demonstrate the use of surface-enhanced Raman spectroscopy (SERS) to determine sialic acid (SA) levels in saliva using silver nanoparticles as substrates, in adnexal mass patients scheduled for surgical intervention to remove invasive masses, with the aim to compare SA levels in benign tumor vs ovarian cancer patients.

Methods: Quantification of SA levels was accomplished by measuring their SERS and calibrating with analytical reagent SA. The mean SA concentration in saliva from 37 benign adnexal mass resulted smaller (5.
