Comparative Study Observational Study
Vessel/perfusion density in two optical coherence tomographic angiography protocols: Interchangeable?
Different optical coherence tomography angiography (OCTA) scanning protocols evaluate the macula. ⋯ Vessel and perfusion densities have high determination coefficients within a scanning protocol, but not between protocols, given that each one preferentially measures different macular areas. Metrics from different protocols should not be interchanged for follow up.

Comparative Study
Sun exposure and sun protection behaviors among teenagers and adults in Mexico City.
To know the prevalence of sun exposure and protection behaviors in a group of adolescents and to compare them with a group of adults in Mexico City. ⋯ There is a similar trend in sun protection and exposure behaviors in adolescents and adults. The prevalence of sunscreen use in adults is high in comparison with adolescents.

In Mexico, suicidal behavior is a matter of concern because, although the rates of death by suicide are below global mean (11.4 vs. 4.1 x 100,000 population), between 1970 and 2007 they increased by 175 %, especially among young people, in whom it is the third leading cause of death. For this reason, several preventive actions have been developed but have not had the expected success, because they are poorly designed. ⋯ This review aims to offer different options, such as adopting the case definition provided by Atlanta's Centers for Disease Control and Prevention (CDC). It aims to broaden the vision in order to include philosophical, psychosocial and psychiatric aspects, as well as to include, as a theoretical framework, the "diathesis-stress" psychological model and propose a population-based intervention preventive strategy.

Multicenter Study
Clinical features of patients with Rocky Mountain spotted fever, dengue and chikungunya infection.
Clinical distinction between arbovirus infections and those caused by rickettsia is crucial to initiate appropriate medical treatment. ⋯ Rash on the palms and soles, edema and absence of pruritus, together with high levels of direct bilirubin and severe thrombocytopenia could be useful indicators to differentiate patients at RMSF advanced stages from those with dengue and chikungunya.

Since its foundation, more than 75 years ago, the Mexican Institute of Social Security (IMSS) has carried out multidisciplinary research -biomedical, clinical and epidemiological- focused on understanding and solving the medical problems that afflict its beneficiaries (more than 50% of the Mexican population). Initially, research was the result of individual and isolated efforts. In the 1960s, a small number of researchers formed the first research groups. ⋯ In addition, approximately 270 doctors carry out clinical research at different primary, secondary and tertiary care units. During these seven decades, IMSS scientists have made relevant contributions to medicine, which have not only helped increase knowledge on the etiopathogenesis of numerous diseases, but also their diagnosis, prognosis and treatment. This article presents an overview of medical research carried out at IMSS, based on a historical approach and a review of some of the most relevant contributions in different fields of research.
