[The general self-efficacy scale (GSES): Reevaluation of its reliability and validity evidence in Chile].
Self-efficacy is a psychological variable closely related to healthy behaviors. One of the most widely used instruments to measure this variable is the general self-efficacy scale (GSES). In Chile, the only psychometric study of this scale has important analytical limitations. ⋯ The GSES is an adequate scale to measure general self-efficacy in the Chilean population and allows unbiased comparisons based on sex or age.

[SARS-CoV-2 infection as a thrombo-inflammatory endothelial disease].
Coronavirus disease 19 is characterized by an intense inflammatory response and a high incidence of thrombotic events. Autopsy studies show severe endothelial injury associated with thrombosis of the alveolar capillaries of the lungs and other organs. ⋯ Heparin is an excellent drug to treat Covid-19 patients due to its anticoagulant, anti-inflammatory, antiviral and endothelial effects. Clinical guidelines agree that the use of heparin thromboprophylaxis is a component of Covid-19 coagulopathy treatment, even though the dose and duration of treatments are not well defined.

[Cancer in Chile and worldwide: an overview of the current and future epidemiological context].
Cancer is a chronic non-communicable disease associated with a high mortality burden. The prevalence of cancer is increasing rapidly worldwide. However, this scenario will be worse in low and middle-income countries such as Chile, where 70% of cancer deaths occur. ⋯ When we reviewed mortality by sex, stomach and prostate cancer were responsible for more than 30% of cancer deaths among men. However, for women the first three places were occupied by breast, colorectal and lung cancer, as in the rest of the world. Considering that 40% of cancers are related to unhealthy lifestyles, working on the prevention of modifiable risk factors represents an opportunity for the creation of public health policies that allow changes at the environmental and individual level.

[Retention of procedural competences in medicine students after training using a simulation model].
Boot camps are used to acquire skills in simple surgical procedures, such as sutures, in a short period of time. ⋯ Simulation programs are useful for the acquisition of procedural skills which are retained over time.

[Equations to estimate body composition using bioelectrical impedance in Chilean adults].
Equations for the evaluation of fat-free mass (FFM) and fat mass (FM) with Bioelectrical impedance analysis (BIA) were formulated in Caucasian populations. International recommendations suggest that population-specific equations should be formulated. ⋯ Both equations behave similarly and have biases, although less with Schifferli. Statistically correcting for biases, the new adjusted equations provide clinically valid estimates of FFM and FM. Equations should not only be population-specific, but also device-specific.
