From 1990 to 2012, the Sanitary and Tropical Diseases Institute experienced the most important changes. In 1989, its name and orientation were modified to become the National Institute of Epidemiological Diagnosis and Reference. Shortly before, it had been formalized as the apex of the National Network of Public Health Laboratories and had incorporated laboratories for preventive programs such as exfoliative cytology and rabies, malaria and tuberculosis diagnosis; subsequently, it would incorporate other networks that emerged as part of the response to major epidemic outbreaks and to the new epidemiological outlook. ⋯ In 2001, the Institute started working with pathogens related to bioterrorism. By then, space restrictions of the headquarter's building were evident; in 2008, starting the construction of new facilities was decided. The Institute and its diagnostic networks constitute a milestone in Latin American public health of the 21st century.

The relationship between the social covenant, ethics and scientific research is highly important for society. Economic prosperity and better health are two of the main reasons why society supports science, without society itself being able to determine the nature of the research that is to be implemented; this is decided by Research Committees (RCs) and Research Ethics Committees (RECs). This article analyzes how the work of RCs and RECs must have a social covenant and represent the interests of society in order to promote its trust in research.

Except for pregnant women, the management of critically ill patients with COVID-19 during the pandemic includes the standard procedures that are used for any patient that requires to be attended to at the intensive care unit, as well as limited administration of crystalloid solutions, orotracheal intubation, invasive mechanical ventilation in the event of patient clinical deterioration, and muscle relaxants continuous infusion only if necessary. Non-invasive mechanical ventilation and high-flow oxygen therapy are not recommended due to the generation of aerosol (associated with risk of viral spread among health personnel), and neither is extracorporeal membrane oxygenation or the use of steroids. So far, there is no specific antiviral treatment for patients with COVID-19, and neither are there results of controlled trials supporting the use of any.

Pregnancies resulting from assisted reproductive technologies (ART) have been documented to have a higher risk of adverse effects. ⋯ Pregnancies by ART are associated with an increased risk of obstetric and perinatal complications in comparison with spontaneous conceptions. Further research is needed to determine which aspects result in higher risk.

Breast milk is a complex biological fluid. Additionally to its nutritional impact, it contains diverse bioactive elements related to early metabolic programming and molecular structures, such as microRNA related to the epigenetic signaling process. ⋯ Apparently the origin of this microbiota is found in the entero-mammary circulation, as well as in the retrograde circulation of the skin of the mammary gland, although it is speculated in what percentage the microbiota of the oral cavity of the infant contributes in a significant way. From a functional point of view, it has been shown the transfer of this microbiota to the infant's digestive tract, which is related to better digestive tolerance, lower frequency and intensity of dysfunctionalities of the brain-intestine-microbiota axis, and improved immunity, among others.
