Background: Studies on the psychometric properties of the Copenhagen Burnout Inventory (CBI) in medical residents are scarce despite their susceptibility to burnout. Moreover, none of these studies were conducted in Spanish., Aim of the Study: To analyze the psychometric properties of the Spanish version of the CBI among Mexican medical residents., Methods: This cross-sectional study was conducted online on medical residents from a public medical institution (n = 525). The English version of the CBI (19 items organized into three domains: personal-related burnout, work-related burnout, and patient-related burnout) was translated into Spanish and again into English. Content, convergent, discriminant, and concurrent validity were assessed, along with reliability., Results: The CBI Spanish version showed acceptable content, convergent and concurrent validity. Exploratory factor analysis showed two factors, but confirmatory factor analysis showed three factors with adequate fit (Root Mean Square Error of Approximation = 0.08, Comparative Fit Index = 0.95, Tucker-Lewis Index = 0.94, and Standardized Root Mean Square Residual = 0.04). There was no good discrimination between personal-related and work-related burnout. Cronbach's alpha coefficients for the personal-related, work-related, and patient-related burnout domains were 0.94, 0.95, and 0.93, respectively., Conclusions: The Spanish version of the CBI in Mexican medical residents is reliable, and it meets adequate content, convergent and concurrent validity. The construct validity was not consistent. This should not diminish the importance of the CBI., (Copyright © 2022. Published by Elsevier Inc.)

Background: Although it is common to use risk factors in the screening for preeclampsia, they do not always accurately identify patients who truly have this condition., Aim of the Study: To determine the discriminatory accuracy of known preeclampsia risk factors, both individually and in combination., Methods: We studied patients undergoing prenatal care who were diagnosed with preeclampsia or eclampsia (n = 160 cases) in primary care and those who were not (n = 430 controls). Data on history of preeclampsia, type 2 diabetes, chronic hypertension, multiple gestation, first pregnancy, pregnancy interval ≥10 years, overweight/obesity, mean arterial pressure (MAP) ≥80 mmHg, and age (<20 years and ≥40 years) were obtained using a dichotomous scale. Discriminatory accuracy indicators were true-positive (TP) and false-positive (FP) rates, positive and negative likelihood ratios (LR+ and LR-), diagnostic odds ratio (DOR), and the area under the receiver-operating characteristic (AUROC) curve; stratified by parity. The case-control status was the reference standard., Results: Certain combinations performed better than individual factors, independent of parity status. Among multiparous women, MAP ≥80 mmHg together with previous preeclampsia and overweight/obesity accumulated the greatest number of discriminatory accuracy indicators, with acceptable values: TP, 72.2%; FP, 1.5%; LR+, 48.4; LR-, 0.3; DOR, 171.6; and AUROC, 0.85., Conclusions: Discriminatory accuracy was low for almost all individual preeclampsia risk factors. However, the accuracy improved after some factors were combined. To the best of our knowledge, this is the first study to examine the discriminatory accuracy of preeclampsia risk factors used for screening high-risk pregnancies in primary care in Mexico., (Copyright © 2018 IMSS.

Background and Aims: Although underlying mechanisms have been described to account for the association between prediabetes and diabetes with breast cancer, reported results have been inconsistent. We undertook this study to determine whether prediabetes and diabetes are risk factors for breast cancer in Mexican women with no family history of breast cancer in the mother, daughters, or sisters., Methods: A case-control study was carried out during 2011-2013. "Case" referred to patients with a histopathological diagnosis of breast cancer (incident and primary cases) (n = 240); "controls" were those with a BI-RADS 1 or 2 mammography result (n = 406). Categorization of prediabetes and diabetes was based on self-reporting or fasting glucose and glycated hemoglobin blood sampling results. Reproductive and sociodemographic data were collected by interview. Odds ratios (ORs) and 95% confidence intervals (CI) were calculated using multivariate unconditional binary logistic regression analysis., Results: Prediabetes increased the risk of breast cancer in postmenopausal women (adjusted OR 2.08, 95% CI 1.10-3.96) as did diabetes (adjusted OR 2.85, 95% CI 1.55-5.26). A history of diabetes preceding breast cancer by ≥7 years and <7 years were both associated with an increased risk for breast cancer (adjusted OR 2.80, 95% CI 1.40-5.60 and 3.00, 95% CI 1.50-5.90, respectively)., Conclusions: This is the first study in Mexico evaluating prediabetes and diabetes as breast cancer risk factors in women with no first-degree relatives with breast cancer. Our findings suggest that women with prediabetes and diabetes should be considered a more vulnerable population for early breast cancer detection., (Copyright © 2014 IMSS. Published by Elsevier Inc.

Background: The objective of this study was to determine the cost of diabetes mellitus, its impact on health spending in Mexico, and its percentage of the gross domestic product (GDP)., Methods: There was a four-stage approach: identification of the epidemiology of the use of health services; estimate of treatment cost; determination of the diabetic population, and calculation of the percentage of health spending., Results: The average annual cost per diabetic patient was $708 U.S. dollars (USD), the total annual cost of diabetics was $2,618,000 USD, the percentage of health spending was 15.48%, and the percentage of the GDP was 0.79%., Conclusions: It is necessary to seek strategies that allow for a more efficient use of resources designated for type 2 diabetes treatment.
