Background: The pandemic of COVID-19 has represented a major threat to global public health in the last century and therefore to identify predictors of mortality among COVID-19 hospitalized patients is widely justified. The aim of this study was to evaluate the possible usefulness of Charlson Comorbidity Index (CCI) as mortality predictor in patients hospitalized because COVID-19. Methods: This study was carried out in Zacatecas, Mexico, and it included 705 hospitalized patients with suspected of SARS-CoV-2 infection. Clinical data were collected, and the CCI score was calculated online using the calculator from the Sociedad Andaluza de Medicina Intensiva y Unidades Coronarias; the result was evaluated as mortality predictor among the patients with COVID-19. Results: 377 patients were positive for SARS-COV-2. Obesity increased the risk of intubation among the study population (odds ratio (OR) = 2.59; 95 CI: 1.36–4.92; p = 0.003). The CCI values were higher in patients who died because of COVID-19 complications than those observed in patients who survived (p < 0.001). Considering a CCI cutoff >31.69, the area under the ROC curve was 0.75, with a sensitivity and a specificity of 63.6% and 87.7%, respectively. Having a CCI value >31.69 increased the odds of death by 12.5 times among the study population (95% CI: 7.3–21.4; p < 0.001). Conclusions: The CCI is a suitable tool for the prediction of mortality in patients hospitalized for COVID-19. The presence of comorbidities in hospitalized patients with COVID-19 reflected as CCI > 31.69 increased the risk of death among the study population, so it is important to take precautionary measures in patients due to their condition and their increased vulnerability to SARS-CoV-2 infection.

Despite the implementation of programmes to improve maternal health, maternal and foetal mortality rates still remain high. The presence of maternal distress and its association with the development of pregnancy hypertensive disorders is not well established. The aim of this study was to evaluate the association between maternal distress and the development of hypertensive disorders in pregnancy in a prospective cohort of 321 Mexican women. Symptoms of maternal distressing were evaluated at week 20th of gestation using the General Health Questionnaire. The presence of acute somatic symptoms, social dysfunction, anxiety and insomnia increased the odds of developing a pregnancy hypertensive disorder by 5.1-26.4 times in study population (p values < .05). Our results support the participation of maternal distress in the development of hypertensive disorders of pregnancy. The implementation of effective programmes prioritising risk factors during pregnancy including the presence of maternal distressing factors is recommended. Impact statement What is already known on this subject: Changes in the nervous, endocrine, and immune systems have been observed in pregnant women with distress conditions leading to gestational disorders. What do the results of this study add: The presence of acute somatic symptoms, social dysfunction, anxiety and insomnia increased the developing of hypertensive disorders in Mexican population. What are the implications of these findings for clinical practice and/or further research: These findings may contribute to a better understanding of the role of the maternal stress in the development of hypertensive disorders of pregnancy, and in the implementation of effective programmes for clinical practice prioritising risk factors during pregnancy, including the presence of maternal distressing factors.

Validez de dos pruebas para evaluar la percepción materna del peso del hijo Salud Publica Mex 2009;51:489-495. ResumenObjetivos. Evaluar la percepción materna del peso del hijo por medio de dos pruebas, percepción por palabras (PP) y percepción por imágenes (PI), así como evaluar la validez de las dos pruebas mediante la determinación de la sensibilidad y especificidad. Material y métodos. Se seleccionó un total de 418 diadas madre-hijo del área urbana de Monterrey Nuevo León; a las madres se les aplicó un cuestionario de percepciones sobre la apariencia física y la salud. Se calculó sensibilidad y especificidad. El índice de masa corporal medido del hijo fue el estándar de oro. Resultados. El 20.34% de madres de niños con sobrepeso (SP) y 7.41% de madres de niños con obesidad (OB) percibieron el sobrepeso por la prueba PP; y 62.71% de madres de niños con SP y 81.48% de niños con OB por la prueba PI. Las madres subestimaron el SP-OB; la sensibilidad y especificidad de la PP fueron de 12 y 21% y las de PI de 75 y 15%, respectivamente. Conclusiones. Las madres de niños con SP-OB subestiman el peso del hijo. Las imágenes son útiles para que las madres reconozcan esta situación.

Validity of two tests to evaluate maternal perception of child's weight. Salud Publica Mex 2009;51:489-495. AbstractObjective. To assess maternal perception of their children weight using words (PP) and using images (PI) and evaluate the validity of the two tests by determining their sensitivity and specificity. Material and Methods. A total of 418 motherchild diads were selected from urban areas in the Monterrey, Nuevo León area. A questionnaire was administered to the mothers about perceptions regarding physical appearance and health. Sensitivity and specificity were calculated and the body mass index measurement of the child was the gold standard. Results. Mothers underestimated overweight (SP) and obesity (OB), with 20.34% of mothers of children with SP and 7.41% of children with OB perceiving their child's condition with the PP test, and 62.71% of mothers of children with SP and 81.48% of those of children with OB perceiving it with the PI test. The tests had 12% sensitivity and 21% specificity for PP and 75% sensitivity and 15% specificity for PI. Conclusions. The mothers of children with SP-OB underestimate the weight of their children. Images are useful for mothers to recognize their child's condition.

r e s U M e n Se identificaron predictores de la percepción materna del peso del hijo (PMPH) con sobrepeso-obesidad (SP-OB). Participaron 2.874 madres e hijos, residentes en el Noreste de México; 951 tenían un hijo con SP-OB. La PMPH se evaluó por palabras (PP) y por imágenes (PI). Por PP, 63.71% y 74.9% de madres de hijos con SP-OB no percibieron adecuadamente el peso del hijo y por PI, 27% y 10.99%. Mediante regresión logística, el modelo para PP fue χ 2 = 152.05, gl = 9, p = 0.001, varianza explicada 21.5% y para PI fue χ 2 = 192.35, gl = 9, p = 0.001, varianza explicada 31.9%. Edad del hijo y si el médico informa de SP en el niño/a, fueron variables que contribuyeron a los modelos. Se concluye que las madres de niños con SP-OB no perciben de forma adecuada esta situación. Se resalta la importancia de informar respecto al SP-OB del hijo. Palabras clave autoresNiño, obesidad, percepción, percepción del peso, reconocimiento, sobrepeso. Palabras clave descriptors a b s T r a c T Several predictors of a mother's perception of her child's weight (MPCW) when the child is overweigh-obese (OW-OB) were identified. Participants: 2,842 mothers and children who reside in Mexico's northeastern region, 951 mothers had an OW-OB child. The MPCW was evaluated for words (PW) and images (PI). PW, 63.71% and 74.9% of the mothers with an OW-OB child, did not perceive the child's weight adequately and PI, 27% and 10.99%. Through Logistic Regression Analysis, a model for PW was χ 2 = 152.05, gl = 9, p = 0.001, 21.5% explained variance; and for PI χ 2 = 192.35, gl = 9, p = 0.001, 31.9% explained variance. The child's age, a doctor's report that the child had OW, were some variables that contributed to the models. We concluded that mothers with OW-OB children * Artículo de investigación.
