[Gene geography of Chile: regional distribution of American, European and African genetic contributions].
The geographical distribution of genes plays a key role in genetic epidemiology. The Chilean population has three major stem groups (Native American, European and African). ⋯ Half of the Chilean population harbors African genes. Participants with Aymara and Mapuche surnames had a higher American genetic contribution than the general Chilean population. These results confirm the usefulness of surnames as a first approximation to determine genetic ancestry.

Guideline[Therapeutic strategies to increase the effectiveness of cough].
Cough is a natural reflex that protects respiratory airways against infections or mucus retention. Cough maintains an adequate cleaning of the airways and is a mainstay of respiratory therapy. It can be triggered voluntarily by the patient or by a specific cough device. ⋯ Different therapeutic measures may help to increase cough efficiency among patients with cough weakness. These interventions may be performed using manual techniques or by mechanical devices. The aim of this review is to analyze the different techniques available for cough assistance, set a hierarchy of use and establish a scientific basis for their application in clinical practice.

[New spirometric reference equations for healthy Chilean adults].
To correctly interpret spirometric results, reference values should come from the same population. Current spirometric reference equations have been under scrutiny due to deficiencies to fit adequately for Chilean population, specially, for those aged over 65 years old. ⋯ The new spirometric references values derived from this study, fit better than currently used ones. Therefore, they should be used as new references values for Chilean adults.

Multicenter Study Observational Study[Information disclosure and decision making preferences of patients with advanced cancer in a Pain and Palliative Care Unit in Chile].
Information disclosure and decision making process are important steps in advanced cancer patients management; however, there is no research done in this area in Chile. ⋯ A majority of patients preferred to receive complete information about diagnosis and prognosis and to make shared decisions. The satisfaction with information disclosure and decision making process was very high. The data of this study supports the need of an adequate information disclosure and of exploring the individual preferences of our patients, with the goal of promoting an informed decision making process that respects the preferences of our patients.
