Review[Inflammation as a common pathogenic factor in coronary artery disease and depression].
A narrative review of the evidence regarding the role of inflammation in the pathophysiology of coronary heart disease and depression is presented. As a common pathogenic factor, inflammation could explain the frequent association of both diseases. We discuss the benefit of exercise and diet modifications in both conditions and the effectiveness and safety of selective serotonin reuptake inhibitors. Finally, we recommend screening for depressive symptoms in coronary patients and the search of cardiovascular risk factors in people with depression.

[Factors associated with sedentary lifestyle and physical inactivity in Chile: a qualitative systematic review].
Sedentary lifestyle and physical inactivity in Chile, has become a major problem and a public health priority in the last decade, as it increases the risk of non-communicable diseases. ⋯ here are independent factors associated with both sedentary lifestyle and physical inactivity in Chile. Some factors are common for the two unhealthy behaviors such as female gender, obesity, type 2 diabetes mellitus and metabolic syndrome.

Review[Unfolded protein response as a target in the treatment of Alzheimer's disease].
The clinical features of Alzheimer's disease (AD), for example the progressive memory loss, are produced by neuronal loss and synaptic dysfunction. These events have been associated with histopathological alterations in AD brain, including the presence of amyloid plaques and neurofibrillary tangles. Recent studies suggest that cellular stress produced by the aggregation of misfolded proteins leads to alterations in protein homeostasis, that is regulated for the most part by endoplasmic reticulum (ER). ⋯ Based on the involvement of ER stress in several diseases, efforts are being done to identify small molecules that can inhibit or activate selective UPR components. Here, we review the findings suggesting a functional role of ER stress in the etiology of AD. Possible therapeutic strategies to mitigate ER stress in the context of AD are discussed.

Cardiovascular diseases and cancer account for 27 and 25% of mortality in Chile, respectively. In the last decades, survival of people with cancer has improved due to preventive programs, early detection strategies, advances in technology and development of new antineoplastic therapies. Consequently, a progressive number of cancer-surviving patients have been generated, who may develop cardiovascular diseases, secondary to the same cancer therapy. ⋯ Also, to acquire knowledge about the mechanisms and effects of drugs that lead to heart damage aiming to develop efficient cardioprotective therapies. In this article we review and propose a didactic organization and classification of the main cardiovascular effects of cancer control therapy. We recognize that there is still a knowledge gap in basic sciences about the mechanisms that underlie these alterations.

[How to interpret systematic reviews with multiple comparisons or network meta-analysis].
Systematic reviews evaluating multiple interventions can be useful in different clinical situations. However, some concerns arise when more than two interventions are compared and there is a paucity of good quality randomized clinical trials. A novel statistical method based on indirect comparisons, called network meta-analysis (NMA), can be a useful approach to find a clinical answer when multiple interventions are evaluated for the same outcome or comparator. The aim of this review is to describe the main characteristics and provide a user guide for a critical analysis of NMA focusing on its three main domains, namely homogeneity, transitivity and consistency.
