RESUMO

Undernutrition is highly prevalent in children who are critically ill and is associated with increased morbidity and mortality, including a higher risk of infection due to transitory immunological disorders, inadequate wound healing, reduced gut function, longer dependency on mechanical ventilation, and longer hospital stays compared with eutrophic children who are critically ill. Nutrition care studies have proposed that early interventions targeting nutrition assessment can prevent or minimize the complications of undernutrition. Stress promotes an acute inflammatory response mediated by cytokines, resulting in increased basal metabolism and nitrogen excretion and leading to muscle loss and changes in body composition. Therefore, the inclusion of body composition assessment is important in the evaluation of these patients because, in addition to the nutrition aspect, body composition seems to predict clinical prognosis. Several techniques can be used to assess body composition, such as arm measurements, calf circumference, grip strength, bioelectrical impedance analysis, and imaging examinations, including computed tomography and dual-energy x-ray absorptiometry. This review of available evidence suggests that arm measurements seem to be well-established in assessing body composition in children who are critically ill, and that bioelectrical impedance analysis with phase angle, handgrip strength, calf circumference and ultrasound seem to be promising in this evaluation. However, further robust studies based on scientific evidence are necessary.

RESUMO

Objectives: To prospectively assess health-related quality of life (HRQoL), global functionality, and disability in primary caregivers of surviving children and adolescents after COVID-19. Methods: A longitudinal observational study was carried out on primary caregivers of surviving pediatric post-COVID-19 patients (n = 51) and subjects without COVID-19 (n = 60). EuroQol five-dimension five-level questionnaire (EQ-5D-5L) and 12-question WHO Disability Assessment Schedule 2.0 (WHODAS 2.0) were answered for both groups. The univariate regression analysis was carried out using SPSS (v 20) and significance was established at 5%. Results: The median duration between COVID-19 diagnosis in children and adolescents and longitudinal follow-up visits was 4.4 months (0.8-10.7). The median age of children and adolescents caregivers with laboratory-confirmed COVID-19 was similar to primary caregivers of subjects without laboratory-confirmed COVID-19 [43.2 (31.6-60.9) vs. 41.5 (21.6-54.8) years, p = 0.08], as well as similar female sex (p = 1.00), level of schooling (p = 0.11), social assistance program (p = 0.28), family income/month U$ (p = 0.25) and the number of household's members in the residence (p = 0.68). The frequency of slight to extreme problems (level ≥ 2) of the pain/discomfort domain according to EQ-5D-5L score was significantly higher in the former group [74% vs. 52.5%, p = 0.03, OR = 2.57 (1.14-5.96)]. The frequency of disability according to WHODAS 2.0 total score was similar to those without disability and unknown (p = 0.79); however, with a very high disability in both groups (72.5% and 78.3%). Further analysis of primary caregivers of children and adolescents with post-COVID-19 condition (PCC) [n = 12/51 (23%)] compared to those without PCC [n = 39/51(77%)] revealed no differences between demographic data, EQ-5D-5L and WHODAS 2.0 scores in both groups (p > 0.05). Conclusion: We longitudinally demonstrated that pain/discomfort were predominantly reported in approximately 75% of primary caregiver of COVID-19 patients, with high disability in approximately three-quarters of both caregiver groups. These data emphasized the prospective and systematic caregiver burden evaluation relevance of pediatric COVID-19.

RESUMO

BACKGROUND: Sodium and chloride disturbances have attracted increasing attention in recent years. Many pathophysiological effects are associated with hyperchloremia, including reduction in mean arterial pressure and acute renal disease. Pediatric patients undergoing liver transplantation are at risk of developing various electrolyte and biochemical abnormalities, with an impact on their postoperative outcomes. OBJECTIVE: To analyze the impacts of serum sodium and chloride levels on prognosis of Pediatric Liver Transplant receptors. METHODS: This was a retrospective analytical observational study performed in a single transplant reference center in Sao Paulo, Brazil. Included patients were pediatric patients who underwent liver transplantation between January 2015 and July 2019. Statistical regression analysis and General Estimating Equations analysis were performed to evaluate the impacts of sodium and chloride disturbances on the development of acute renal failure and mortality. RESULTS: A total of 143 patients were included in this study. The main diagnosis was Biliary Atresia (62.9%). Twenty-seven patients died (18.9%), and graft dysfunction was the main cause of death (29.6%). The only variable individually associated with 28-days mortality was PIM-3 score (HR 1.59, CI 95% 1.165-2.177, p = 0.004). Forty-one patients (28.6%) developed moderate or severe AKI. PIM-3 score (OR 3.052, 95% CI 1.56-5.97, p = 0.001), hypernatremia (OR 3.49, 95% CI 1.32-9.23, p = 0.012), and hyponatremia (OR 4.24, 95% CI 1.52-11.85, p = 0.006) were independently associated with the development of moderate/severe AKI. CONCLUSIONS: In pediatric patients after liver transplantation, PIM-3 score, and abnormal serum sodium levels were correlated with AKI development.

RESUMO

OBJECTIVES: To evaluate the inconsistency between clinical diagnosis of death and autopsy findings in adolescents with chronic diseases. METHODS: A cross-sectional study including a sample of adolescents' autopsies who died in a pediatric and adolescent tertiary hospital over 18 consecutive years. During this period, there were n = 2912 deaths, and n = 581/2912(20%) occurred in adolescents. Of these, n = 85/581(15%) underwent autopsies and were analyzed. Further results were divided into two groups: Goldman classes I or II (high disagreement between main clinical diagnosis of death and anatomopathological findings, n = 26) and Goldman classes III, IV or V (low or no disagreement between these two parameters, n = 59). RESULTS: Median age at death (13.5 [10‒19] vs. 13 [10‒19] years, p = 0.495) and disease duration (22 [0‒164] vs. 20 [0‒200] months, p = 0.931), and frequencies for males (58% vs. 44%, p = 0.247) were similar between class I/II vs. class III/IV/V. The frequency of pneumonia (73% vs. 48%, p = 0.029), pulmonary abscess (12% vs. 0%, p = 0.026), as well as isolation of yeast (27% vs. 5%, p = 0.008), and virus (15% vs. 2%, p = 0.029) identified in the autopsy, were significantly higher in adolescents with Goldman class I/II compared to those with Goldman class III/IV/V. In contrast, cerebral edema was significantly lower in adolescents of the first group (4% vs. 25%, p = 0.018). CONCLUSION: This study showed that 30% of the adolescents with chronic diseases had major discrepancies between clinical diagnosis of death and autopsy findings. Pneumonia, pulmonary abscess, as well as isolation of yeast and virus were more frequently identified at autopsy findings in the groups with major discrepancies.

RESUMO

ABSTRACT Objectives: To evaluate mortality in adolescents and young adult patients with chronic diseases followed in a Latin American tertiary hospital. Methods: A cross-sectional retrospective study was performed in a tertiary/academic hospital in the state of São Paulo, Brazil. Death occurred in 529/2850 (18.5%) adolescents and young adult patients with chronic diseases, and 25/529 (4.7%) were excluded due to incomplete medical charts. Therefore, 504 deaths were evaluated. Results: Deaths occurred in 316/504 (63%) of early adolescent patients and in 188/504 (37%) of late adolescent/young adult patients. Further comparisons between early adolescents (n = 316) and late adolescent/young adult patients (n = 188) with pediatric chronic diseases at the last hospitalization showed that the median disease duration (22.0 [0-173] vs. 43.0 [0-227] months, p < 0.001) was significantly lower in early adolescents vs. late adolescent/young adult patients. The median number of previous hospitalizations was significantly lower in the former group (4.0 [1-45] vs. 6.0 [1-52], p < 0.001), whereas the last hospitalization in intensive care unit was significantly higher (60% vs. 47%, p = 0.003). Regarding supportive measures, palliative care was significantly lower in the younger group compared to the older group (33% vs. 43%, p = 0.02). The frequencies of renal replacement therapy (22% vs. 13%, p = 0.02), vasoactive agents (65% vs. 54%, p = 0.01), and transfusion of blood products (75% vs. 66%, p = 0.03) were significantly higher in the younger group. The five most important etiologies of pediatric chronic diseases were: neoplasias (54.2%), hepatic diseases/transplantation (10%), human immunodeficiency virus (5.9%), and childhood-onset systemic lupus erythematosus and juvenile idiopathic arthritis (4.9%). Autopsy was performed in 58/504 (11%), and discordance between clinical and postmortem diagnoses was evidenced in 24/58 (41.3%). Conclusions: Almost 20% of deaths occurred in adolescents and young adults with distinct supportive care and severe disease patterns. Discordance between clinical diagnosis and autopsy was frequently observed.


RESUMO Objetivos: Avaliar a mortalidade entre adolescentes e pacientes adultos jovens com doenças crônicas acompanhados em um hospital terciário na América Latina. Métodos: Foi feito um estudo retrospectivo transversal em um hospital terciário/universitário no Estado de São Paulo, Brasil. Houve mortalidade de 529/2.850(18,5%) pacientes adolescentes e adultos jovens com doenças crônicas, porém 25/529(4,7%) foram excluídos devido a prontuários médicos incompletos. Portanto, foram avaliados 504 óbitos. Resultados: Ocorrem 316/504(63%) óbitos entre pacientes no início da adolescência e 188/504(37%) pacientes no fim da adolescência/adultos jovens. As comparações adicionais entre os pacientes no início da adolescência (n = 316) e no fim da adolescência/pacientes jovens (n = 188) com doenças crônicas pediátricas na última internação mostraram que a duração média da doença [22,0 (0-173) em comparação com 43,0 (0-227) meses, p < 0,001], foi significativamente menor nos pacientes no início da adolescência em comparação com os pacientes no fim da adolescência/adultos jovens. O número médio de internação anterior foi significativamente menor no primeiro grupo [4,0 (1-45) em comparação com 6,0 (1-52), p < 0,001], ao passo que a última internação na unidade de terapia intensiva foi significativamente maior (60% em comparação com 47%, p = 0,003). Com relação a medidas de suporte, o cuidado paliativo foi significativamente menor no grupo de pacientes no início da adolescência em comparação com o grupo de pacientes no fim da adolescência (33% em comparação com 43%, p = 0,02). As frequências de terapia de substituição renal (22% em comparação com 13%, p = 0,02), agentes vasoativos (65% em comparação com 54%, p = 0,01) e transfusão de hemoderivados (75% em comparação com 66%, p = 0,03) foram significativamente maiores no primeiro grupo. As cinco etiologias mais importantes de doenças crônicas pediátricas foram: neoplasias (54,2%), doenças hepáticas/transplante (10%), vírus da imunodeficiência humana (5,9%), lúpus eritematoso sistêmico de início na infância e artrite idiopática juvenil (4,9%). Foi feita autópsia em 58/504 (11%) e a discordância entre os diagnósticos clínico e pós-morte foi comprovada em 24/58 (41,3%). Conclusões: Quase 20% dos óbitos ocorreram em adolescentes e adultos jovens com diferentes padrões de cuidados de suporte e doenças graves. A discordância entre o diagnóstico clínico e a necropsia foi frequentemente observada.

RESUMO

OBJECTIVE: Opioid abstinence syndrome is common in the pediatric intensive care environment because sedation is often needed during the children's treatment. There is no specific guideline regarding the management of these patients; and lately, methadone is an important drug for the prevention of abstinence symptoms during the weaning of opioids. This study gathers the available research to establish the initial dose of methadone, the rate of taper and tools to recognize this syndrome and act promptly. METHODS: A systematic review was made from data of four different databases. Forty-nine articles of observational and experimental studies were selected based on the inclusion criteria (critical pediatric patients in acute use of opioids) and exclusion criteria (previous chronic use of opioids, other medications). The data regarding specific themes were separated in sections: initial dose of methadone, use of protocols in clinical practice, abstinence scales and adjuvant drugs. RESULTS: The articles showed a great heterogeneity of ways to calculate the initial dose of methadone. The pediatric intensive care units of the study had different weaning protocols, with a lower incidence of abstinence when a pre-defined sequence of tapering was used. The Withdrawal Assessment Tool - 1 was the most used scale for tapering the opioids, with good sensitivity and specificity for signs and symptoms. CONCLUSION: There is still little evidence of other medications that can help prevent the abstinence syndrome of opioids. This study tries to promote a better practice during opioid weaning.

RESUMO OBJETIVO: A síndrome de abstinência de opioides é comum no ambiente de terapia intensiva pediátrica porque a sedação é frequentemente necessária durante o tratamento das crianças. Não existe uma diretriz específica sobre o manejo desse paciente e, ultimamente, a metadona tem sido uma droga importante para a prevenção dos sintomas de abstinência durante o desmame dos opioides. Este estudo reúne as pesquisas disponíveis para estabelecer a dose inicial de metadona, taxa de redução e ferramentas para reconhecer essa síndrome e agir prontamente. MÉTODOS: Uma revisão sistemática foi feita a partir de dados de quatro diferentes bases de dados. Quarenta e nove artigos, de estudos observacionais e experimentais, foram selecionados com base nos critérios de inclusão (pacientes críticos pediátricos em uso de opioides agudamente) e critérios de exclusão (uso crônico prévio de opioides, outros medicamentos). Os dados referentes a temas específicos foram separados em seções: dose inicial de metadona, uso de protocolos na prática clínica, escalas de abstinência e drogas adjuvantes. RESULTADOS: Os artigos mostraram uma grande heterogeneidade de formas de calcular a dose inicial de metadona. As unidades de terapia intensiva pediátrica do estudo apresentaram diferentes protocolos de desmame, com menor incidência de abstinência quando foi utilizada uma sequência predefinida de redução gradual. A Ferramenta de Avaliação de Retirada - 1 foi a escala mais utilizada durante a redução dos opioides, com boa sensibilidade e especificidade para sinais e sintomas. CONCLUSÃO: Ainda há poucas evidências de outros medicamentos que possam ajudar a prevenir a síndrome de abstinência dos opioides. Este estudo tenta promover uma prática melhor durante o desmame dos opioides.

RESUMO

OBJECTIVES: Limited knowledge exists regarding the lipid profiles of critically ill pediatric patients with systemic inflammatory response syndrome. The aim of this study was to evaluate the relationship between the intensity of the inflammatory response and changes in the lipid profiles of critically ill pediatric patients admitted to a pediatric intensive care unit (PICU) with severe sepsis/septic shock. METHODS: This was a prospective and observational study at a 15-bed PICU at a public university hospital. We analyzed the lipid profiles of 40 patients with severe sepsis/septic shock admitted to the PICU on the first and seventh days of hospitalization. C-reactive protein was used as a marker for systemic inflammation. Forty-two pediatric patients seen in the emergency department and without systemic inflammatory response syndrome were used to provide control values. RESULTS: On day 1 of admission to the PICU, the patients had significantly lower levels of total cholesterol (TC), high-density lipoprotein (HDL), and low-density lipoprotein (LDL) as well as higher concentrations of triacylglycerols compared with the control group. There was a significant increase in the TC, HDL, LDL, and apolipoprotein levels from day 1 to day 7 of the study. CONCLUSIONS: During severe sepsis/septic shock, we found lower serum levels of lipoproteins and apolipoproteins, and these were negatively correlated with C-reactive protein. As the inflammatory response improved, the levels of TC, HDL, LDL, and apolipoproteins increased, suggesting a direct relationship between changes in the lipid profiles and inflammation.

RESUMO

OBJECTIVES: Children admitted to PICUs often present with or develop respiratory failure that requires mechanical ventilation. We prospectively identified children admitted to three general PICUs, with the goal of identifying risk factors for mortality. DESIGN: Prospective multicenter observational study. SETTING: Three general PICUs, two in São Paulo and one in Curitiba, Brazil. PATIENTS: Children aged between 1 month and 15 years, consecutively admitted between August 2008 and July 2010, with acute lung injury or acute respiratory distress syndrome that developed at least 12 hours after invasive or noninvasive mechanical ventilation. INTERVENTIONS: None. MEASUREMENTS AND MAIN RESULTS: We used logistic regression models to explore the relationship between death and independent variables. Of 3,046 patients admitted to the three PICUs, 1,658 patients underwent mechanical ventilation, and 84 fulfilled the acute lung injury/acute respiratory distress syndrome inclusion criteria and were analyzed. Nearly 60% were boys, and the median age was 31 months. Pressure control/assist control was the initial mode of mechanical ventilation in 86% of cases, and the median durations of mechanical ventilation and PICU stay were 12 and 15 days, respectively. None of the eight patients with acute lung injury died, whereas 33 of 76 of the remaining patients with acute respiratory distress syndrome died, for an overall mortality rate of 39.3% (95% CI, 28.8-50.6%). In different multivariate logistic regression model, the number of organ dysfunctions at admission, peak inspiratory pressure, airway pressure gradient on day 1, and the mean airway pressure gradient over the first 7 days of mechanical ventilation were significantly associated with mortality. CONCLUSION: Mortality is high in pediatric acute lung injury/acute respiratory distress syndrome. Mechanical ventilation-associated risk factors for death among such patients are potential targets for intervention.

RESUMO

BACKGROUND: Focused echocardiographic examinations performed by intensivists and emergency room physicians can be a valuable tool for diagnosing and managing the hemodynamic status of critically ill children. The aim of this study was to evaluate the learning curve achieved using a theoretical and practical training program designed to enable pediatric intensivists and emergency physicians to conduct targeted echocardiograms. METHODS: Theoretical and practical training sessions were conducted with 16 pediatric intensivist/emergency room physicians. The program included qualitative analyses of the left ventricular (LV) and right ventricular (RV) functions, evaluation of pericardial effusion/cardiac tamponade and valvular regurgitation and measurements of the distensibility index of the inferior vena cava (dIVC), ejection fraction (EF) and cardiac index (CI). The practical training sessions were conducted in the intensive care unit; each student performed 24 echocardiograms. The students in training were evaluated in a practical manner, and the results were compared with the corresponding examinations performed by experienced echocardiographers. The evaluations occurred after 8, 16 and 24 practical examinations. RESULTS: The concordance rates between the students and echocardiographers in the subjective analysis of the LV function were 81.3% at the first evaluation, 96.9% at the second evaluation and 100% at the third evaluation (p < 0.001). For the dIVC, we observed a concordance of 46.7% at the first evaluation, 90.3% at the second evaluation and 87.5% at the third evaluation (p = 0.004). The means of the differences between the students' and echocardiographers' measurements of the EF and CI were 7% and 0.56 L/min/m2, respectively, after the third stage of training. CONCLUSIONS: The proposed training was demonstrated to be sufficient for enabling pediatric physicians to analyze subjective LV function and to measure dIVC, EF and CI. This training course should facilitate the design of other echocardiography training courses that could be implemented in medical residency programs to improve these physicians' technical skills and the care of critically ill patients.
