ObjectiveTo describe the epidemiology of acute kidney injury, its relationship to chronic kidney disease, and the factors associated with its incidence.MethodsA cohort study and follow-up were conducted in an intensive care unit in Montevideo, Uruguay. We included patients admitted between November 2014 and October 2015 who were older than 15 years of age and who had at least two measurements of serum creatinine. We excluded patients who were hospitalized for less than 48 hours, patients who died at the time of hospitalization, and patients with chronic renal disease who were on hemodialysis or peritoneal dialysis. There were no interventions. Acute kidney injury was defined according to the criteria set forth in Acute Kidney Injury Disease: Improving Global Outcomes, and chronic kidney disease was defined according to the Chronic Kidney Disease Work Group.ResultsWe included 401 patients, 56.6% male, median age of 68 years (interquartile range (IQR) 51-79 years). The diagnosis at admission was severe sepsis 36.3%, neurocritical 16.3%, polytrauma 15.2%, and other 32.2%. The incidence of acute kidney injury was 50.1%, and 14.1% of the patients suffered from chronic kidney disease. The incidence of acute septic kidney injury was 75.3%. Mortality in patients with or without acute kidney injury was 41.8% and 14%, respectively (p < 0.001). In the multivariate analysis, the most significant variables for acute kidney injury were chronic kidney disease (odds ratio (OR) 5.39, 95%CI 2.04 - 14.29, p = 0.001), shock (OR 3.94, 95%CI 1.72 - 9.07, p = 0.001), and severe sepsis (OR 7.79, 95%CI 2.02 - 29.97, p = 0.003).ConclusionThe incidence of acute kidney injury is high mainly in septic patients. Chronic kidney disease was independently associated with the development of acute kidney injury.
Introduction:The guidelines to prophylaxis of infectious endocarditis changed, but many congenital heart diseases continue to be considered as high risk for the development of the disease.Objective: To evaluate the knowledge of parents or guardians of children and adolescents with congenital heart disease seen at a referral center in Rio Grande do Sul, Brazil on infective endocarditis and its prevention.Methods: Cross-sectional study with 90 patients with congenital heart defects in regular outpatient treatment. The parents' knowledge was assessed using a specific questionnaire and other data were obtained through medical records.Results: The median age of patients was 5.6 years (3 months -14 years), being 57,7% males. The median follow-up time in service was 3.49 years (1.20-7.38). The years of formal schooling of the parents had a mean of 7.67 ± 3.25 years. According to the score previously established, the knowledge of the interviewed parents was considered satisfactory in 37.7%, regular in 33.3% and unsatisfying in 28,8%. There was significant correlation between the index of parentsḱ nowledge and monitoring of children at service (r=0.584; P=0.796). There was no correlation between parentsé ducation and knowledge of them (r=0.028; P=0.796). Conclusion:The parents' knowledge about endocarditis and its prevention was inadequate, requiring greater attention to the orientations passed in consultations.Descriptors: Primary Prevention. Endocarditis. Knowledge. Resumo
Background The effects of in-utero exposure to maternal SARS-CoV-2 infection on the offspring's neurodevelopment are still unknown.Methods We performed a prospective cohort of babies exposed to SARS-Cov-2 during pregnancy, and a control group of unexposed babies in a low-income area in Northeastern Brazil. All data were prospectively collected from medical records. Children’s neurodevelopment was assessed using the guide for Monitoring Child Development in the IMCI context and the Ages & Stages Questionnaire (ASQ-3), at ages 4, 6, and 12 months. Maternal depressive symptoms were assessed using the Edinburgh Postnatal Depression Scale (EPDS).Results We followed 127 children for one year, 69 children in the COVID-19 exposed Group (EG), and 68 in the control group (CG). All mothers were unvaccinated at the time included in the cohort. Maternal demographics were similar in the two groups, but prematurity was more prevalent in mothers infected with COVID-19 (21.7% vs. 8.8%, p = .036) and EPDS scores were also significantly higher among the EG (M = 11.00, SD = 6.00 vs. M = 8.68, SD = 4.72, p = 0.04). Both groups had similar rates of cesarean delivery, Apgar scores, average birth weight, head circumference and length at birth. 20.3% of EG children and 5.9% of the CG received a diagnosis of neurodevelopmental delay within 12 months of life (p = 0.013, RR = 3.44; 95% CI, 1.19–9.95). 10% of EG children presented abnormalities at the cranial ultrasound.Conclusions COVID-19 exposure was associated with neurodevelopmental impairment. This study highlights the importance of specific guidelines in the follow-up of children exposed to in-utero SARS-CoV-2 in order to mitigate or prevent long-term effects on children’s health.
