Zika virus (ZIKV) infection in pregnancy is associated with severe abnormalities of the brain and eye and other adverse outcomes. Zika en Embarazadas y Niños was a prospective cohort study conducted in multiple Colombian cities that enrolled pregnant women in their first trimester. Specimens collected from pregnant women (n = 1,519) during February 2017-September 2018 and their infants (n = 1,080) during June 2017-March 2019 were tested for prenatal ZIKV infection by nucleic acid amplification tests or IgM antibody testing.

- The study evaluated Zika virus (ZIKV) knowledge and attitudes among pregnant women in Colombia during its outbreak, focusing on their preventive behaviors against mosquito-borne and sexual transmission.
- Data was gathered from 1,519 women in early pregnancy; most were aware of ZIKV transmission (97.8%) and expressed concern (85.5%), though preventive behaviors like using mosquito repellent were low (17.0%).
- Despite having good knowledge about ZIKV, there was no clear link between this knowledge and behavioral changes, although a history of mosquito-borne infection did correlate with increased condom use.
Project (VEZ), an intensified surveillance of pregnant women with symptoms of the Zika virus disease (ZVD) in Colombia, aimed to evaluate the relationship between symptoms of ZVD during pregnancy and adverse pregnancy, birth, and infant outcomes and early childhood neurodevelopmental outcomes. During May-November 2016, pregnant women in three Colombian cities who were reported with symptoms of ZVD to the national surveillance system, or with symptoms of ZVD visiting participating clinics, were enrolled in Project VEZ. Data from maternal and pediatric (up to two years of age) medical records were abstracted.

- A study in Colombia evaluated maternal and infant cytomegalovirus (CMV) infections by testing maternal serum for CMV antibodies early in pregnancy and analyzing infant urine for CMV DNA.
- The maternal CMV seroprevalence was very high at 98.1%, indicating most mothers had been exposed to the virus.
- Congenital CMV prevalence was found to be 8.4 per 1000 live births, and of the infants without congenital infection, over half (54.7%) were diagnosed with postnatal infection by 6 months of age.
Cardiac surgery after mediastinal radiation: extent of exposure influences outcome.

Objectives: Mediastinal radiation for thoracic malignancies uses multiple treatment fields and doses. We investigated whether more extensive radiation exposure is associated with more hospital complications and worse survival after cardiac surgery.
Methods: From January 2000 to January 2005, 230 patients underwent cardiac surgery after 3 levels of mediastinal radiation: extensive (Hodgkin disease, thymoma, and testicular cancer; n = 70), variable (eg, non-Hodgkin lymphoma and lung cancer; n = 35); and tangential (breast cancer; n = 125).
