Brain anatomopathological findings in neonates with congenital heart disease.

Introduction: Neonates with congenital heart disease can develop neurological problems, which is why it is important to know the time and extent at which these lesions occur in order to elucidate their causes and implications.

Objective: To describe brain morphological alterations in autopsies of neonates with congenital heart disease.

Methods: The cases of neonates with congenital heart disease and complete autopsy registered in the pathology department from 2009 to 2019 were included.

Neurological repercussions of changes in cerebral blood flow in neonates undergoing cardiovascular surgery.

Introduction: Surgery for congenital heart disease can generate cerebral perfusion-associated alterations with neurological repercussions.

Objective: To analyze the relationship of peri-surgical cerebrovascular resistance index (RI) with mediate neurological functions after congenital heart disease surgery.

Method: Prospective cohort study of 34 neonates in whom basilar artery RI, serum oxygen, carbon dioxide and lactate levels were determined before and after palliative or corrective procedures.

Risk Factors for Central Line-Associated Bloodstream Infection in Critically Ill Neonates.

Objective: To identify independent risk factors to develop a central line- associated bloodstream infection (CLABSI) in critically ill neonates with major underlying diseases.

Methods: A nested case-control study was conducted in a neonatal intensive care unit (NICU). Patients with a central venous catheter (CVC) were included.

Risk Factors for Intracardiac Thrombosis in the Right Atrium and Superior Vena Cava in Critically Ill Neonates who Required the Installation of a Central Venous Catheter.

Background: Central venous catheter (CVC) installation is essential for the treatment of critically ill neonates; however, it is associated with the development of neonatal intracardiac thrombosis, which is a complication that is associated with a poor prognosis. We aimed to identify specific risk factors for the development of intracardiac thrombosis in the right atrium (RA) and superior vena cava (SVC) related to the use of CVC in critically ill neonates.

Methods: A case-control study was conducted at the tertiary referral neonatal intensive care unit of the Pediatric Hospital Siglo XXI in Mexico City, Mexico from 2008 to 2013.

[Research in pediatrics].

In the interest of encouraging the promotion of research done by physicians of the Instituto Mexicano del Seguro Social, in this supplement we publish articles written by residents of different specialties related to critical themes on pediatrics. These residents are guided by affiliated physicians from the Hospital de Pediatría del Centro Médico Nacional Siglo XXI.

[Reliability and validity of an instrument to evaluate integral clinical competence in medical residents].

Background: The evaluation of clinical competence in medical residents is a complex procedure. Teachers need reliable and valid instruments to evaluate objectively the, clinical competence. The aim of this study was to determine the reliability and validity of an instrument designed to evaluate the clinical competence of medical residents.
