Objective. To briefly describe the process of establishment and preliminary results of the Mérida Population-based Cancer Registry (Mérida-PBCR) Materials and methods. Mérida-PBCR started in 2016 as a research project in the IMSS, with a gradual increase in its information sources. It covers a population of 908 536 inhabitants. Data collection is active and passive, international standards are used; CanReg5 software enables data entry, storage and analysis. Results. Current data include 71.5% of sources. For the period 2015- 2016, a total of 2 623 new cancer cases were registered, the majority of these (60.1%) among females. 81.5% of the cases had morphological verification. Prostate (17.4%), colorectal (8.5%) and stomach (8.1%) cancers were the most common among males, and breast (31.6%), cervix (12%) and corpus uteri (7.6%) cancers, the most common among females. Ageadjusted cancer incidence rates (per 100 000) for all sites combined were 114.9 among males and 145.1 among females. Conclusion. The implementation of the Mérida-PBCR has followed particular parameters, with important efforts to include new information sources. Although the data are still preliminary and must be interpreted with great caution, the main cancers follow a similar pattern to that of the national and regional estimates. [ABSTRACT FROM AUTHOR]

Objective: To describe the mammographic findings and carcinoma detection rate in asymptomatic women of Mexico City, that participated in an opportunistic screening program., Materials and Methods: 39 491 participants were included, with mammograms performed and interpreted in the National Cancer Institute, from 2008 to 2011. The mammographic findings, type of lesion and true positives (TP), are described by age groups. We calculated the crude effect of age on the classification BIRADS (Breast Imaging Reporting and Data System) 0 and the type of lesion., Results: The median age was 50 (45-57) years. 80.5% were classified as BIRADS 2, 11.4%(0), 4.1%(1), 3.5%(3), 0.5%(4) y 0.1%(5). Malignant lesions were detected in 1.3 and 3.3 per 1000 and the proportion of true positives (TP) was 8.2% and 20.6%, in women of 41-50 and 51-70 years, respectively., Conclusions: Although some cases are detected in women 40 to 50 years, in women over 50 years the screening by mammography is more efficient, with a higher proportion of cases detected and fewer false positives.

Objective: To estimate the magnitude of diabetes in Mexico, as well as discuss alternative policies to face it appropriately., Materials and Methods: Descriptive analysis of the National Health and Nutrition Survey 2012, using reported information on previous diagnosis of diabetes from adults and adolescents., Results: From all adults 20 years and older in Mexico, 9.17% has been diagnosed with diabetes, presenting an important geographical heterogeneity, ranging from 5.6% in the southern state of Chiapas, to 12.3% in Mexico City. Of all people with diabetes, 46.95% also have been diagnosed with hypertension, 4.47% has had a stroke, and 54.46%, reported family background of diabetes. Regarding adolescents, 0.68% has been already diagnosed with diabetes., Conclusions: The burden of diabetes in Mexico and the fact that is a preventable condition, calls to strengthen the health sector strategies to face it. The negative effect it has on the quality of life makes diabetes a priority for the health sector.

Objective: Determine the influence of nutritional counseling, exercise, access to social healthcare and drugs, and the quality of medical care on the control of diabetics., Material and Methods: The information and blood samples were obtained in 2005. Glycemic control was defined as good if HbA1c was ≤7.0%, poor from 7.01%-9.50% and very poor if HbA1c >9.5%. Binary logistic regression models were used to determine the association of these factors with HbA1c>9.5%., Results: Thirty percent of the patients with a medical diagnosis of diabetes had adequate metabolic control., Conclusions: Nutritional guidance was associated with an increase in the degree of control. A majority of diabetics have poor or very poor glycemic control. Strengthening the quality of and access to medical care for these patients is urgently needed.
