ABSTRACT
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.
ABSTRACT
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.
