Incidence and risk factors of abdominal compartment syndrome in pediatric oncology patients: a prospective cohort study.

Abdominal compartment syndrome (ACS) has been the subject of increasing research over the past decade owing to its effects on morbidity and mortality in critically ill patients. This study aimed to determine the incidence and risk factors of ACS in patients in an onco-hematological pediatric intensive care unit in a middle-income country and to analyze patient outcomes. This prospective cohort study was conducted between May 2015 and October 2017. Altogether, 253 patients were admitted to the PICU, and 54 fulfilled the inclusion criteria for intra-abdominal pressure (IAP) measurements. IAP was measured using the intra-bladder indirect technique with a closed system (AbViser AutoValve®, Wolfle Tory Medical Inc., USA) in patients with clinical indications for indwelling bladder catheterization. Definitions from the World Society for ACS were used. The data were entered into a database and analyzed. The median age was 5.79 years, and the median pediatric risk of mortality score was 7.1. The incidence of ACS was 27.7%. Fluid resuscitation was a significant risk factor for ACS in the univariate analysis. The mortality rates in the ACS and non-ACS groups were 46.6% and 17.9%, respectively (P < 0.05). This is the first study of ACS in critically ill children with cancer.   Conclusion: The incidence and mortality rates were high, justifying IAP measurement in children with ACS risk factors.

Content validation of a questionnaire to assess the knowledge of pediatricians, family, and community physicians on obesity.

OBJECTIVE: The aim of this study was to validate the content of a questionnaire in order to assess the attitudes and practices in childcare consultations, knowledge on overweight and obesity, their risk factors, and barriers in addressing the issue by pediatricians and family physicians. METHODS: The Delphi technique was used, with the objective of reaching a consensus on a certain subject, through experts' opinions. The content validity index (CVI) of each item, axis, and questionnaire was calculated. The inter-rater reliability was calculated using an agreement coefficient suitable for the answer distribution such as Gwet's AC2 with ordinal weight. RESULTS: A total of 63 experts were invited to assess and give their opinion on the questionnaire. In all, 52 accepted the invitation and analyzed the instrument. After two rounds, the questionnaire reached the proper CVI for the study and was considered complete, with its final version having 40 questions, a final index of 95%, and an inter-rate reliability of 0.905. CONCLUSIONS: This instrument, developed to assess attitudes and practices, knowledge, and barriers found in addressing the obesity by primary care physicians, obtained a CVI greater than 0.8 and an excellent agreement coefficient of the 52 judges. Therefore, its content can be considered validated.

Knowledge of gynecologists in the public health system care of women victims of violence.

OBJECTIVE: This study aimed to evaluate the knowledge of the obstetricians and gynecologists in the care of women victims of violence in the public health system and the existence of institutional mechanisms to support them. METHODS: A cross-sectional and observational study was conducted with an electronic questionnaire by physicians who provided care in the obstetrics and gynecology emergency unit of the public health system. This study aimed to identify the care for victims of violence who received the institutional mechanisms of support, the difficulties encountered in determining the appropriate care, and estimates of the prevalence of violence against women. RESULTS: Notably, 92 physicians responded to the questionnaire. Of these, 85% had already provided care in one or more cases of violence, and 60% believed that <20% of the women received adequate care in these cases, mainly due to the short-time frame of the consultation, lack of team preparation, and lack of institutional resources. A total of 61% of the participants believed that they were not prepared to provide adequate care in those cases. CONCLUSIONS: Most of the physicians interviewed, although reported to have sufficient knowledge to adequately treat victims of violence, did not provide such care due to lack of institutional support.

Factors associated with multidrug-resistant bacteria in healthcare-associated infections: a pediatric intensive care unit case-control study.

OBJECTIVE: To investigate the prevalence of factors related to healthcare-associated infections, caused by multidrug-resistant bacteria, in a pediatric intensive care unit. METHODS: A retrospective case-control study conducted from January 1, 2007 to December 31, 2018, in São Paulo (SP), Brazil. The study was carried out at the pediatric intensive care unit of a high-complexity, tertiary care general hospital. The study included patients aged 1 month to 19 years, admitted to the pediatric intensive care unit, diagnosed as healthcare-associated infections. RESULTS: There was significant evidence of infection by multidrug-resistant bacteria associated with immunosuppressed patients (p<0.001), in whom the likelihood of multidrug-resistant bacteria infection was estimated to be nine-fold higher than among non-immunosuppressed patients (OR 8.97; 95%CI 2.69-29.94). In the analysis of multiple logistic regression model, we observed that immunosuppressed patients had an 8.5-fold higher chance of multidrug-resistant bacteria infection when compared to non-immunosuppressed patients (OR 8.48; 95%CI 2.54-28.35; p=0.001). There is evidence of association between the Case Group and presence of Gram-positive (p=0.007), coagulase-negative Staphylococcus (p<0.001), and Gram-negative (p=0.041) microorganisms. CONCLUSION: The immunocompromised-state variable is a factor related to healthcare-associated infections caused by multidrug-resistant bacteria, and the Case Group presented higher proportions of Gram-positive microorganisms and coagulase-negative Staphylococcus.

Epidemiology and treatment of sepsis at a public pediatric emergency department.

OBJECTIVE: To describe the clinical characteristics and treatment of children with sepsis, severe sepsis, and septic shock at a pediatric emergency department of a public hospital. METHODS: A retrospective, observational study. The medical records of patients included in the hospital Pediatric Sepsis Protocol and patients with discharge ICD-10 A41.9 (sepsis, unspecified), R57 (shock) and A39 (meningococcal meningitis) were evaluated. RESULTS: A total of 399 patients were included. The prevalence of sepsis, severe sepsis, and septic shock at the emergency room were 0.41%, 0.14% and 0.014%, respectively. The median age was 21.5 months for sepsis, 12 months for severe sepsis, and 20.5 months for septic shock. Sepsis, severe sepsis, and septic shock were more often associated with respiratory diseases. The Respiratory Syncytial Virus was the most common agent. The median time to antibiotic and fluid administration was 3 hours in patients with sepsis and severe sepsis. In patients with septic shock, the median times to administer antibiotics, fluid and vasoactive drugs were 2 hours, 2.5 hours and 6 hours, respectively. The median length of hospital stay for patients with sepsis, severe sepsis and septic shock were 3 days, 4 days and 1 day, respectively. The overall mortality was 2%. CONCLUSION: Sepsis had a low prevalence. Early diagnosis and recognition are a challenge for the emergency care pediatrician, the first place of admission.

The impact of monitoring software on antimicrobial management in a pediatric intensive care unit.

INTRODUCTION: Antimicrobial stewardship programs are necessary practices to combat resistance in hospital infections. However, studies frequently cite the scarcity of technological resources as an obstacle to the comprehensive development of ASPs. OBJECTIVES: The aim of the study was to assess the impact of monitoring software on reducing antibiotic consumption and reducing resistance in a pediatric intensive care unit. METHODS: We conducted an analytical longitudinal study during the period January 1, 2007, to December 31, 2018, in the pediatric intensive care unit of a high-complexity tertiary general hospital in Brazil. RESULTS: In the period after the implementation of software, we observed decreases in total antimicrobial consumption (P = .037). Regarding Enterobacterales, we observed a decrease in the proportion of antimicrobial resistance of first and second-generation cephalosporin classes (P = .041) and third and fourth-generation cephalosporins (P = .028). There was a decrease in the proportion of resistance of nonfermenting gram-negative bacilli to aminoglycoside scans (P = .016). We also observed evidence of a decrease in the proportion of resistance of Staphylococcus aureus agents to oxacillin (P < .001). CONCLUSIONS: The monitoring software reduced the total consumption of antimicrobials and decreased the proportion of resistance, therefore demonstrating its importance in controlling the development of multidrug-resistant bacteria.

A Pediatric Sepsis Protocol Reduced Mortality and Dysfunctions in a Brazilian Public Hospital.

Introduction: Few studies in the literature discuss the benefits of compliance with sepsis bundles in hospitals in low- and middle-income countries, where resources are limited and mortality is high. Methods: This is a retrospective cohort study conducted at a public hospital in a low-income region in Brazil. We evaluated whether completion of a sepsis bundle is associated with reduced in-hospital mortality for sepsis, severe sepsis, and septic shock, as well as prevention of septic shock and organ dysfunction. Bundle compliance required the completion of three items: (1) obtaining blood count and culture, arterial or venous blood gases, and arterial or venous lactate levels; (2) antibiotic infusion within the first hour of diagnosis; and (3) infusion of 10-20 ml/kg saline solution within the first hour of diagnosis. Results: A total of 548 children with sepsis, severe sepsis, or septic shock who were treated at the emergency room from February 2008 to August of 2016 were included in the study. Of those, 371 patients were included in the protocol group and had a lower median length of stay (3 days vs. 11 days; p < 0.001), fewer organ dysfunctions during hospitalization (0 vs. 2, p < 0.001), and a lower probability of developing septic shock. According to a propensity score analysis, mortality was lower during the post-implementation period [2.75 vs. 15.4% (RR 95%IC 0.13 (0.06, 0.27); p < 0.001)]. Conclusions: A simple and low-cost protocol was feasible and yielded good results at a general hospital in a low-income region in Brazil. Protocol use resulted in decreased mortality and progression of dysfunctions and was associated with a reduced probability of developing septic shock.

Barriers and Proposed Solutions to a Successful Implementation of Pediatric Sepsis Protocols.

The implementation of managed protocols contributes to a systematized approach to the patient and continuous evaluation of results, focusing on improving clinical practice, early diagnosis, treatment, and outcomes. Advantages to the adoption of a pediatric sepsis recognition and treatment protocol include: a reduction in time to start fluid and antibiotic administration, decreased kidney dysfunction and organ dysfunction, reduction in length of stay, and even a decrease on mortality. Barriers are: absence of a written protocol, parental knowledge, early diagnosis by healthcare professionals, venous access, availability of antimicrobials and vasoactive drugs, conditions of work, engagement of healthcare professionals. There are challenges in low-middle-income countries (LMIC). The causes of sepsis and resources differ from high-income countries. Viral agent such as dengue, malaria are common in LMIC and initial approach differ from bacterial infections. Some authors found increased or no impact in mortality or increased length of stay associated with the implementation of the SCC sepsis bundle which reinforces the importance of adapting it to most frequent diseases, disposable resources, and characteristics of healthcare professionals. Conclusions: (1) be simple; (2) be precise; (3) education; (5) improve communication; (5) work as a team; (6) share and celebrate results.

The epidemiology of sepsis in paediatric intensive care units in Brazil (the Sepsis PREvalence Assessment Database in Pediatric population, SPREAD PED): an observational study.

BACKGROUND: Data on the prevalence and mortality of paediatric sepsis in resource-poor settings are scarce. We aimed to assess the prevalence and in-hospital mortality of severe sepsis and septic shock treated in paediatric intensive care units (PICUs) in Brazil, and risk factors for mortality. METHODS: We performed a nationwide, 1-day, prospective point prevalence study with follow-up of patients with severe sepsis and septic shock, using a stratified random sample of all PICUs in Brazil. Patients were enrolled at each participating PICU on a single day between March 25 and 29, 2019. All patients occupying a bed at the PICU on the study day (either admitted previously or on that day) were included if they were aged 28 days to 18 years and met the criteria for severe sepsis or septic shock at any time during hospitalisation. Patients were followed up until hospital discharge or death, censored at 60 days. Risk factors for mortality were assessed using a Poisson regression model. We used prevalence to generate national estimates. FINDINGS: Of 241 PICUs invited to participate, 144 PICUs (capacity of 1242 beds) included patients in the study. On the day of the study, 1122 children were admitted to the participating PICUs, of whom 280 met the criteria for severe sepsis or septic shock during hospitalisation, resulting in a prevalence of 25·0% (95% CI 21·6-28·8), with a mortality rate of 19·8% (15·4-25·2; 50 of 252 patients with complete clinical data). Increased risk of mortality was associated with higher Pediatric Sequential Organ Failure Assessment score (relative risk per point increase 1·21, 95% CI 1·14-1·29, p<0·0001), unknown vaccination status (2·57, 1·26-5·24; p=0·011), incomplete vaccination status (2·16, 1·19-3·92; p=0·012), health care-associated infection (2·12, 1·23-3·64, p=0·0073), and compliance with antibiotics (2·38, 1·46-3·86, p=0·0007). The estimated incidence of PICU-treated sepsis was 74·6 cases per 100 000 paediatric population (95% CI 61·5-90·5), which translates to 42 374 cases per year (34 940-51 443) in Brazil, with an estimated mortality of 8305 (6848-10 083). INTERPRETATION: In this representative sample of PICUs in a middle-income country, the prevalences of severe sepsis or septic shock and in-hospital mortality were high. Modifiable factors, such as incomplete vaccination and health care-associated infections, were associated with greater risk of in-hospital mortality.

Prevalence and outcomes of sepsis in children admitted to public and private hospitals in Latin America: a multicenter observational study. / Prevalência e desfechos da sepse em crianças internadas em hospitais públicos e privados na América Latina: um estudo observacional multicêntrico.

OBJECTIVE: To report the prevalence and outcomes of sepsis in children admitted to public and private hospitals. METHODS: Post hoc analysis of the Latin American Pediatric Sepsis Study (LAPSES) data, a cohort study that analyzed the prevalence and outcomes of sepsis in critically ill children with sepsis on admission at 21 pediatric intensive care units in five Latin American countries. RESULTS: Of the 464 sepsis patients, 369 (79.5%) were admitted to public hospitals and 95 (20.5%) to private hospitals. Compared to those admitted to private hospitals, sepsis patients admitted to public hospitals did not differ in age, sex, immunization status, hospital length of stay or type of admission but had higher rates of septic shock, higher Pediatric Risk of Mortality (PRISM), Pediatric Index of Mortality 2 (PIM 2), and Pediatric Logistic Organ Dysfunction (PELOD) scores, and higher rates of underlying diseases and maternal illiteracy. The proportion of patients admitted from pediatric wards and sepsis-related mortality were higher in public hospitals. Multivariate analysis did not show any correlation between mortality and the type of hospital, but mortality was associated with greater severity on pediatric intensive care unit admission in patients from public hospitals. CONCLUSION: In this sample of critically ill children from five countries in Latin America, the prevalence of septic shock within the first 24 hours at admission and sepsis-related mortality were higher in public hospitals than in private hospitals. Higher sepsis-related mortality in children admitted to public pediatric intensive care units was associated with greater severity on pediatric intensive care unit admission but not with the type of hospital. New studies will be necessary to elucidate the causes of the higher prevalence and mortality of pediatric sepsis in public hospitals.

OBJETIVO: Relatar a prevalência e os desfechos da sepse em crianças admitidas em hospitais públicos e privados na América Latina. MÉTODOS: Análise post-hoc dos dados do Latin American Pediatric Sepsis Study (LAPSES), um estudo de coorte que avaliou a prevalência e os desfechos da sepse em crianças admitidas em 21 unidades de terapia intensiva pediátricas de cinco países latino-americanos. RESULTADOS: Dentre os 464 pacientes com sepse, 369 (79,5%) foram admitidos em hospitais públicos e 95 (20,5%) em privados. Em comparação com os admitidos em hospitais privados, os pacientes com sepse admitidos em hospitais públicos não diferiram em termos de idade, sexo, condição de imunização, tempo de permanência no hospital ou tipo de admissão, porém tiveram incidência mais alta de choque séptico, escores Pediatric Risk of Mortality (PRISM), Pediatric Index of Mortality 2 (PIM 2) e Pediatric Logistic Organ Dysfunction (PELOD) mais altos e taxas mais elevadas de doenças de base e analfabetismo materno. A proporção entre pacientes admitidos a partir de enfermarias pediátricas e mortalidade relacionada à sepse foi mais alta nos hospitais públicos. A análise multivariada não mostrou qualquer correlação entre mortalidade e tipo de hospital, porém, nos hospitais públicos, a mortalidade se associou com níveis mais altos de gravidade no momento da admissão à unidade de terapia intensiva. CONCLUSÃO: Nesta amostra de crianças admitidas em condições críticas em cinco países latino-americanos, a prevalência de choque séptico nas primeiras 24 horas da admissão e a mortalidade relacionada à sepse foram mais elevadas em hospitais públicos do que nos privados. A mortalidade relacionada à sepse mais elevada em crianças admitidas em unidades de terapia intensiva pediátrica de hospitais públicos se associou com maior gravidade por ocasião da admissão à unidade de terapia intensiva, porém não com o tipo de hospital. São necessários novos estudos para elucidar as causas da maior prevalência e mortalidade de sepse pediátrica em hospitais públicos.

Vomiting in newborns as a result of a duodenal membrane: two case reports.

Vomiting episodes in newborns are extremely common and often attributed to gastroesophageal reflux. The symptoms of vomiting, however, may be caused by other complications. In this report, we present two cases of a 1-month-old male and a 2-month-old female, both presenting vomiting episodes that led to malnutrition. Some pediatricians often attribute the diagnosis of gastroesophageal reflux to newborns that are vomiting; however, there is a portion of the population that has other causes that lead to similar symptoms. The pediatrician should be alert to the clinical signs of weight loss, dehydration and malnutrition to investigate other causes of vomiting.

Length of stay in pediatric intensive care unit: prediction model.

OBJECTIVE: To propose a predictive model for the length of stay risk among children admitted to a pediatric intensive care unit based on demographic and clinical characteristics upon admission. METHODS: This was a retrospective cohort study conducted at a private and general hospital located in the municipality of Sao Paulo, Brazil. We used internal validation procedures and obtained an area under ROC curve for the to build of the predictive model. RESULTS: The mean hospital stay was 2 days. Predictive model resulted in a score that enabled the segmentation of hospital stay from 1 to 2 days, 3 to 4 days, and more than 4 days. The accuracy model from 3 to 4 days was 0.71 and model greater than 4 days was 0.69. The accuracy found for 3 to 4 days (65%) and greater than 4 days (66%) of hospital stay showed a chance of correctness, which was considering modest. Conclusion: Our results showed that low accuracy found in the predictive model did not enable the model to be exclusively adopted for decision-making or discharge planning. Predictive models of length of stay risk that consider variables of patients obtained only upon admission are limit, because they do not consider other characteristics present during hospitalization such as possible complications and adverse events, features that could impact negatively the accuracy of the proposed model.
