It is not just about prescription. A cohort study of the impact of enteral nutrition on mortality of hospitalized patients with CoVID-19 / No es solo una prescripción. Estudio de cohorte del impacto de la nutrición enteral en la mortalidad de pacientes hospitalizados con COVID-19

Introduction: during COVID-19 pandemic, international societies released guidelines and recommendations for patients requiring nutritionalsupport according to previous similar respiratory diseases.Objectives: the aim of the study was to evaluate the nutritional support provided by enteral nutrition (EN) in patients with COVID-19 infection,identify if the recommendations from international societies were met and their impact on mortality rate.Methods: a cohort study was conducted on adult patients with COVID-19 admitted to a tertiary hospital. Demographic, clinical, biochemical, andnutritional variables were obtained. A random-effect parametric survival-time model was performed to quantify the risk of death for each variable,and the Hausman test was used to confirm the model.Results: two hundred and twenty-nine patients were enrolled. The delivered energy was > 80 % of adequacy in the first two days, as suggestedby international guidelines (11.7 ± 4.9 kcal/kg); however, an adequacy rate less than 60 % was achieved on day 14 (25.4 ± 7.4 kcal/kg). Theprotein adequacy was > 75 % on the first days of infusion (1.3 ± 0.3 g/kg); however, the infusion was < 50 % (1.5 ± 0.4 g/kg) after being extu-bated. Age, sex, and nutritional risk were related to higher mortality in patients with EN, whereas the infused energy and protein, the percentageof protein adequacy, arginine, and n-3 PUFA were associated with lower mortality.Conclusion: achieving at least 80 % of the energy and protein requirements, as well as n-3 PUFA and arginine supplementation could be asso-ciated with lower mortality in COVID-19 patients. More studies are needed to confirm the role of these nutrients on the mortality rate.(AU)

Introducción: durante la pandemia de COVID-19, las sociedades internacionales publicaron guías y recomendaciones para pacientes querequieren apoyo nutricional basándose en lo previamente recomendado en enfermedades respiratorias similares.Objetivos: evaluar el soporte nutricional con nutrición enteral (NE) en pacientes con COVID-19 e identificar el cumplimiento de las recomenda-ciones hechas por las sociedades internacionales y su impacto en la tasa de mortalidad.Métodos: estudio de cohorte en adultos con COVID-19 ingresados en un hospital de tercer nivel. Se registraron variables demográficas, clínicas,bioquímicas y nutricionales. Se realizó un modelo de supervivencia de efectos aleatorios para cuantificar el riesgo de muerte para cada variabley la prueba de Hausman para confirmar el modelo.Resultados: se incluyeron 229 pacientes. La energía administrada fue > 80 % de adecuación en los dos primeros días (11,7 ± 4,9 kcal/kg);sin embargo, fue < 60 % el día 14 (25,4 ± 7,4 kcal/kg). La adecuación de proteínas fue > 75 % en los primeros días de infusión (1,3 ± 0,3g/kg), pero < 50 % (1,5 ± 0,4 g/kg) después de ser extubado. La edad, el sexo y el riesgo nutricional se relacionaron con mayor mortalidad,mientras que la energía y proteína infundidas, el porcentaje de adecuación proteica, la arginina y el contenido de ácidos grasos poliinsaturados(AGPI) n-3 se asociaron con menor mortalidad.Conclusión: aunque se necesitan más estudios para confirmarlo, alcanzar al menos el 80 % de los requerimientos energéticos y proteicos, asícomo la suplementación de fórmulas con AGPI n-3 y arginina, podría asociarse con menor mortalidad en pacientes con COVID-19.(AU)

Dynamic inflammatory response among routine laboratory biomarkers and their predictive ability for mortality in patients with severe COVID-19.

Background: The severity of coronavirus disease 2019 (COVID-19) is related to several factors, including age, sex, and comorbidities (obesity, type 2 diabetes, and hypertension). However, systemic inflammation plays a fundamental role in COVID-19 pathophysiology. Several studies have described this association employing specific biomarkers that are not routinely used in clinical practice. On the other hand, very few reports in the literature focused on the analysis of the routine laboratory biomarkers to predict the outcome of severe COVID-19 patients. Objective: We aimed to analyze the dynamic inflammatory response using routine laboratory biomarkers to predict in-hospital mortality in Mexican patients with severe COVID-19. Methods: This is a cohort study including patients with severe COVID-19. Demographic characteristics were retrieved from medical charts and biochemical parameters were measured at hospital admission and subsequently on days 3, 5, 7, 10, 14, and 21 during the hospital stay; measurements were stopped when patients were discharged from the hospital (alive or death). Results: A total of 250 patients were included in the study, 40.8% of patients died. The analyzed routine laboratory parameters, such as serum levels of neutrophil-to-lymphocyte ratio, C-reactive protein, and D-dimer remained elevated in hospitalized patients who did not survive, whereas eosinophil and platelets were maintained at lower levels. In the multivariate analysis, leukocytes, and neutrophils were the best biomarkers for predicting mortality risk and were independent of age, gender, or comorbidities. Conclusion: Our results support the use of routine laboratory biomarkers as predictors of mortality in Mexican hospitalized patients with severe COVID-19.

Prognostic Factors at Diagnosis Associated With Damage Accrual in Childhood-Onset Systemic Lupus Erythematosus Patients.

Objectives: To associate prognostic factors present at diagnosis with damage accrual in childhood-onset systemic lupus erythematosus (cSLE) patients. Methods: We designed a cohort study of eligible children age 16 or younger who fulfilled the 1997 American College of Rheumatology (ACR) classification criteria for SLE. Excluded were those with previous treatment of steroids or immunosuppressants. The diagnosis date was cohort entry. We followed up on all subjects prospectively for at least 2 years. Two experts assessed the disease activity with the Systemic Lupus Erythematosus Disease Activity Index (SLEDAI) and Mexican-SLEDAI (MEX-SLEDAI) every 3-6 months. Damage was measured annually, applying Pediatric Systemic Lupus International Collaborating Clinics/American College of Rheumatology Damage Index (SDI) to their last visit. We analyzed prognostic factors by relative risks (RR) and used logistic regression to construct the clinimetric table. Results: Ninety patients with a median age of 11.8 years at diagnosis had a SLEDAI score of 15.5 (2-40) and a MEX-SLEDAI score of 12 (2-29); and of them, forty-eight children (53%) had SDI ≥ 2. The associated variables to damage (SDI ≥ 2) are as follows: neurologic disease RR 9.55 [95% CI 1.411-64.621]; vasculitis RR 2.81 [95% CI 0.991-7.973], and hemolytic anemia RR 2.09 [95% CI 1.280-3.415]. When these three features are present at diagnosis, the probability of damage ascends to 98.97%. Conclusion: At diagnosis, we identified neurologic disease, vasculitis, and hemolytic anemia as prognostic factors related to the development of damage in cSLE. Their presence should lead to a closer follow-up to reduce the likelihood of damage development.

Pediatric Abusive Head Trauma: Multicentric Experience in Mexico.

Abusive head trauma (AHT) is one of the most severe forms of child abuse due to its morbidity and mortality. However, AHT is still misdiagnosed in developing countries because of its nonspecific clinical picture and limited knowledge of it on the part of physicians. The aim of this study was to describe some characteristics of children with AHT, their families, and caregivers, as well as the clinical data that could serve as signs for its suspicion and the medical-legal resolution of the cases. Children suspect with AHT in emergency rooms in three Mexican hospitals were included after obtaining informed consent from the parents. All information was obtained from the parents by means of a questionnaire and from different clinical and radiological evaluations of the clinical records of the patients. 15 children, with a median age of 5 months and predominantly males (73.33%), were included in the study. 66% reported a history of irritability periods, and most of the patients (73.33%) had more than one habitual caregiver. The diagnosis of AHT was suspected in only 33.33% on admission in the Emergency Services. Acute symptomatology was present in 53.33%, while less severe symptoms were reported in the rest. Special attention should be paid on babies with history of irritable periods. When a child who is previously healthy and suddenly presents with a seizure or cardiorespiratory dysfunction or brought to the hospital dead, the diagnosis of AHT should be considered as a priority.
