Comparative Study Observational Study[Comparison between self-reported and device measured physical activity according to nutritional status].
It is unknown if nutritional status could influence the accuracy of self-reported physical activity (PA) levels. ⋯ The measurement of PA by means of a self-report questionnaire was discrepant with its objective measurement with an accelerometer. The discrepancy is even higher in obese people.

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.

Relationship between anthropometric nutritional status and functional capacity in older adults living in the community.
The functional fitness of older people may be associated with their nutritional status. ⋯ Functional fitness of older adults is influenced by nutritional anthropometric measures, particularly BMI, WHtR and FM for aerobic capacity, and BMI for upper limb flexibility.

[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.

Case Reports[Bilateral renal papillary necrosis of spontaneous resolution as a cause of microscopic hematuria. Report of one case].
Renal papillary necrosis is an infrequent cause of hematuria characterized by ischemic necrosis of the renal medulla, especially the papilla. Its most common cause is analgesic abuse. ⋯ We report a 63-year-old female studied for an asymptomatic microscopic hematuria whose tomographic study showed a bilateral renal papillary necrosis. No etiology was found, and she evolved with a spontaneous complete remission.
