ObjectiveTo evaluate the accuracy and precision of HemoCue 201 (HemoCue) and Masimo Pronto 7 (Masimo) devices for measuring hemoglobin (Hb) in epidemiological studies, having venous blood samples as a gold standard.Material and methodsWe measured Hb concentrations in a field sample of 148 children from one to five years of age. Masimo and HemoCue were used for capillary blood samples and an automatic analyzer for venous blood samples. Regression models with no intercept were constructed to measure precision and predictability, concordance correlations to measure accuracy and precision, and Bland-Altman limits of agreement as well as hierarchical linear models to estimate variance.ResultsBoth HemoCue and Masimo underestimated Hb concentrations compared to the gold standard. They respectively yielded the following results: regression coefficients of 0.887 and 0.876 with 98.7% and 98.6% predictability; concordance correlation coefficients of 0.183 (p<0.001) and 0.166 (p<0.001); and Bland-Altman variances of -1.51 and -1.62. With regard to Masimo specifically, the three-level Hierarchical Linear Model showed that 57.9% of total variance stemmed from random errors in repeated measures from the same subject.ConclusionsHemoCue and Masimo measure lower Hb concentrations than the gold standard. Their accuracy and precision levels are comparable. It is essential to ensure proper use of devices through enhanced training of field workers.

Objectives To describe trends in the proportion of key food groups (KFG) for public health consumption among low income Mexican women (LIMW). Methods From National Surveys of Health and Nutrition a sample of 655 LIMW in 2012, 1158 in 2016 and 2835 in 2018 was analyzed. From a food frequency questionnaire, foods and beverages were classified into 13 KFG: fruits, vegetables, legumes, meats, poultry and fish, plain water, egg and dairy products, cured meats, fast food and fried Mexican snacks, salty snacks, candies and desserts, sweetened cereals, sweetened beverages and sweetened dairy beverages. Consumption was defined if a KFG was consumed at least 10 grams/day and 3 days/week, 7 days/week was the criterion for fruits, vegetables and plain water. The proportion of LIMW that consumed each KFG was compared through time. Results There were greater decreases in the proportion of LIMW which consumed salty snacks, candies and desserts, sweetened cereals and cured meats, egg and dairy products. Moderate reductions were found in sweetened beverages, legumes and meats, poultry and fish. Less than 40% of LIMW consumed fruits and less than 30% vegetables, with no changes. Approximately 15% of LIMW did not drink water daily. (Table 1). Conclusions Important decreases in consumption of KFG in LIMW were found. Further research is needed in order to understand which factors could be related with those changes. Funding Sources Mexican Ministry of Health.

Conclusion According to Earle et al. indicators, the patients were excessively treated with antineoplastic drugs at the end of life, which demanded more healthcare services. However, they received good support care from palliative care at the end of life. There are no European studies including all indicators for patients with solid tumours near death. Standards to assess the aggressive care at the end of life would be helpful in improvingstrategies at the end of life.

Objectives To assess diet diversity in a national sample of children less than five years old from the lower socioeconomic tertile. Methods Data used in the present analysis comes from the National Health and Nutrition Survey ENANSUT-PROSPERA 2018 (Social inclusion program). Information from 2131 children between 1 and < 5 years old was analyzed. By using a semi-quantitative food and beverages frequency consumption questionnaire a diet diversity indicator was constructed, such indicator classified the foods in 13 groups according to their nutritional characteristics and finally divided them into two great groups: Recommended Foods Group(RFG) like fruits, vegetables, legumes, non-processed meats, dairy products and pure water and Not Recommended for regular consumption (NRFG), a group that include processed meats, fast food, fried or greasy Mexican traditional foods, snacks, sweets, desserts, sweetened cereals, dairy and non-dairy sweetened beverages. A score was calculated with the sum of the consumed food groups for each category. Results The most consumed food groups were: water, dairy products, snacks, sweets and desserts and non-dairy sweetened beverages. Less than 50% (CI 95% 39.9, 54.9) of the children consumed fruits and less than 20% (CI 95% 12.4, 24.9) reported to eat vegetables daily. Consumption of recommended foods mean was 3.7 and not recommended 2.6. Conclusions The diversity of the diet should be considered in more general terms, since it is likely related to a better quality of the diet as a whole. Is fundamental to encourage recommended feeding habits in children, because it is in this age where lifetime behaviors are acquired. NRFG consumption must be avoided considering the current overweight prevalence in the Country. Funding Sources Funding by PROSPERA.

ObjectiveEvaluate the accuracy and precision of Hemocue 201 (Hemocue) and Masimo Pronto 7 (Masimo) devices for measuring hemoglobin in epidemiological studies using having as a gold standard venous blood samples.Material and methodsIn a field sample of 148 children aged 1–5 years were subjects to measure Hemoglobin (Hb) using Masimo, and a capillary blood sample for Hemocue; and a venous blood sample for an automatic analyzer. We constructed regression models with no intercept, for precision and predictability; concordance correlations for accuracy and precision; Band and Altman limits of agreement, and thierarchical linear models for measurement system variance diagnostics.ResultsBoth devices under estaimated Hb concentartions compared with gold standard. Hemocue and Masimo devices have regression coefficients of 0.887 and 0.876 with predictability of 98.7% and 98.6% respectively. Concordance correlation coefficients for Hemocue was 0.18341, (p<0.001) and for Masimo 0.16638, (p<0.001). Bland and Altman showed a difference of −1.51 for Hemocue and −1.62 for Masimo. The three level hierarchical linear model shows that 57.9% of the total variance for Masimo came from repeated measure on same subjects.ConclusionsHemocue and Masimo measure less concentrations of Hb than the gold standard. The accuracy and presicion of Hb measurements with Hemocue and Masimo devices are very similar in the field. Devices should be used properly in field work, based on enhanced training schedules.
