Relevance and quality of implementation research proposals to face the challenges of public health in Latin-America and the Caribbean.

Objectives: To analyse the relevance and quality of the research proposals submitted to the 2016 call for proposals for the initiative Improving Programme Implementation through Embedded Research (iPIER-2016) to address current public health challenges in Latin America and the Caribbean.

Methods: We performed a cross-sectional study using information from 108 research proposals using quantitative and qualitative methods. We used three frameworks to analyse the relevance of the proposals: The Global Burden of Disease, the WHO Health Systems Conceptual Framework and the Sustainable Development Goals proposed in 2015 by the United Nations.

Human papillomavirus (HPV) is a DNA virus linked to mucosal and cutaneous carcinogenesis. More than 200 different HPV types exist. We carried out a transversal study to investigate the prevalence of HPV types in two regions of Mexico.

The Frequency and Type of K-RAS Mutations in Mexican Patients With Colorectal Cancer: A National Study.

Background: Current metastatic colorectal cancer (mCRC) therapy uses monoclonal antibodies against the epidermal growth factor receptor. This treatment is only useful in the absence of K-RAS gene mutations; therefore the study of such mutations is part of a personalized treatment. The aim of this work is to determine the frequency and type of the most common K-RAS mutations in Mexican patients with metastatic disease by nucleotide sequencing.
