Medical specialties' teaching is an area of health systems that deserves special consideration in light of the lessons learned from influenza and COVID-19; educational programs and implementation of the training strategies that are used must be reevaluated, since the level of training of most specialty students does not allow to consider them as personnel who can face these global problems. The number of specialization courses has exponentially grown, and their main threat is the cancellation or partial execution of their academic programs as a consequence of not implementing functional operational strategies during a contingency.

In the efforts to explain COVID-19 pathophysiology, studies are being carried out on the correspondence between the expression of SARS-CoV-2 cell receptors and viral sequences. ACE2, CD147 and TMPRSS2 receptors expression could indicate poorly explored potential infection targets. ⋯ RNA and viral receptor proteins expression was observed in numerous anatomical sites, which partially coincides with the information reported in the literature. High expression in testicular cells markedly stood out, and it would be therefore important ruling out whether this anatomical site is a SARS-CoV-2 reservoir; otherwise, germ cell damage, as it is observed in infections with other RNA viruses, should be determined.

COVID-19 arrived in Latin America early in March 2020. Currently, strategies are being developed in Colombia focusing on the quarantine and social and economic capital reactivation, whereby the expected results are not being obtained. In this article, we propose to review scientific evidence-based literature where information on the operation and adaptation of health systems, and social, economic and solidarity sectors of Colombia is presented. The purpose is to identify COVID-19 implications in the network that provides health services, quality of life and health-disease prognosis in the country, which is not prepared to face crises of social nature and of health systems, as well as the economic and solidarity impacts that are brought about by pandemics and crude episodes of disease.

Adipose tissue is an endocrine organ with high metabolic activity. Countless adipose tissue-secreted adipokines and lipokines, as well as peptides and lipids with biological activity have thus far been discovered. ⋯ The purpose of this review is to report on the most recent findings related to adipose tissue according to its color and its relationship with metabolic alterations associated with obesity. After a review of the specialized literature, white, brown and beige adipocyte populations were identified to be able to coexist within the same structure, and to modify global metabolic state in physiological or pathological situations.

As of March 23, 2020, suspension of non-essential activities was declared in Mexico throughout the country in order to mitigate the spread of the COVID-19 pandemic. ⋯ In Mexico, social distancing is being applied, but studies are still required on the dynamics of the epidemic, person-to-person transmission, incidence of subclinical infections, and patient survival.
