Influence of different methods for calculating gestational age at birth on prematurity and small for gestational age proportions: a systematic review with meta-analysis.

BACKGROUND: Recognizing premature newborns and small-for-gestational-age (SGA) is essential for providing care and supporting public policies. This systematic review aims to identify the influence of the last menstrual period (LMP) compared to ultrasonography (USG) before 24 weeks of gestation references on prematurity and SGA proportions at birth. METHODS: Systematic review with meta-analysis followed the recommendations of the PRISMA Statement. PubMed, BVS, LILACS, Scopus-Elsevier, Embase-Elsevier, and Web-of-Science were searched (10-30-2022). The research question was: (P) newborns, (E) USG for estimating GA, (C) LMP for estimating GA, and (O) prematurity and SGA rates for both methods. Independent reviewers screened the articles and extracted the absolute number of preterm and SGA infants, reference standards, design, countries, and bias. Prematurity was birth before 37 weeks of gestation, and SGA was the birth weight below the p10 on the growth curve. The quality of the studies was assessed using the New-Castle-Ottawa Scale. The difference between proportions estimated the size effect in a meta-analysis of prevalence. RESULTS: Among the 642 articles, 20 were included for data extraction and synthesis. The prematurity proportions ranged from 1.8 to 33.6% by USG and varied from 3.4 to 16.5% by the LMP. The pooled risk difference of prematurity proportions revealed an overestimation of the preterm birth of 2% in favor of LMP, with low certainty: 0.02 (95%CI: 0.01 to 0.03); I2 97%). Subgroup analysis of USG biometry (eight articles) showed homogeneity for a null risk difference between prematurity proportions when crown-rump length was the reference: 0.00 (95%CI: -0.001 to 0.000; I2: 0%); for biparietal diameter, risk difference was 0.00 (95%CI: -0.001 to 0.000; I2: 41%). Only one report showed the SGA proportions of 32% by the USG and 38% by the LMP. CONCLUSIONS: LMP-based GA, compared to a USG reference, has little or no effect on prematurity proportions considering the high heterogeneity among studies. Few data (one study) remained unclear the influence of such references on SGA proportions. Results reinforced the importance of qualified GA to mitigate the impact on perinatal statistics.

Newborn Skin Maturity Medical Device Validation for Gestational Age Prediction: Clinical Trial.

BACKGROUND: Early access to antenatal care and high-cost technologies for pregnancy dating challenge early neonatal risk assessment at birth in resource-constrained settings. To overcome the absence or inaccuracy of postnatal gestational age (GA), we developed a new medical device to assess GA based on the photobiological properties of newborns' skin and predictive models. OBJECTIVE: This study aims to validate a device that uses the photobiological model of skin maturity adjusted to the clinical data to detect GA and establish its accuracy in discriminating preterm newborns. METHODS: A multicenter, single-blinded, and single-arm intention-to-diagnosis clinical trial evaluated the accuracy of a novel device for the detection of GA and preterm newborns. The first-trimester ultrasound, a second comparator ultrasound, and data regarding the last menstrual period (LMP) from antenatal reports were used as references for GA at birth. The new test for validation was performed using a portable multiband reflectance photometer device that assessed the skin maturity of newborns and used machine learning models to predict GA, adjusted for birth weight and antenatal corticosteroid therapy exposure. RESULTS: The study group comprised 702 pregnant women who gave birth to 781 newborns, of which 366 (46.9%) were preterm newborns. As the primary outcome, the GA as predicted by the new test was in line with the reference GA that was calculated by using the intraclass correlation coefficient (0.969, 95% CI 0.964-0.973). The paired difference between predicted and reference GAs was -1.34 days, with Bland-Altman limits of -21.2 to 18.4 days. As a secondary outcome, the new test achieved 66.6% (95% CI 62.9%-70.1%) agreement with the reference GA within an error of 1 week. This agreement was similar to that of comparator-LMP-GAs (64.1%, 95% CI 60.7%-67.5%). The discrimination between preterm and term newborns via the device had a similar area under the receiver operating characteristic curve (0.970, 95% CI 0.959-0.981) compared with that for comparator-LMP-GAs (0.957, 95% CI 0.941-0.974). In newborns with absent or unreliable LMPs (n=451), the intent-to-discriminate analysis showed correct preterm versus term classifications with the new test, which achieved an accuracy of 89.6% (95% CI 86.4%-92.2%), while the accuracy for comparator-LMP-GA was 69.6% (95% CI 65.3%-73.7%). CONCLUSIONS: The assessment of newborn's skin maturity (adjusted by learning models) promises accurate pregnancy dating at birth, even without the antenatal ultrasound reference. Thus, the novel device could add value to the set of clinical parameters that direct the delivery of neonatal care in birth scenarios where GA is unknown or unreliable.

Perinatal risk factors and Apgar score ≤ 3 in first minute of life in a referral tertiary obstetric and neonatal hospital.

This study aimed to identify the maternal, labour and newborn risk factors associated with an Apgar score of ≤3 in the first minute of life. This was a cross-sectional evaluation from an internal database information system in a tertiary referral obstetric and neonatal centre. Newborns with gestational age ≥24 weeks and birth weight ≥500 g with a registered Apgar score in the first minute of life were included. A total of 4475 newborns had an Apgar score >3 and 154 newborns had an Apgar score ≤3 in the first minute of life. A multivariate analysis revealed that eclampsia (OR = 31.53), twin pregnancy (OR = 7.06), analgesia (OR = 1.97), prematurity (OR = 2.00) and caesarean section (OR = 2.06) were risk factors for an Apgar score ≤3 in the first minute of life. Identification of these risk factors indicates prompt assistance during prenatal and labour care to prevent neonatal hypoxia and low Apgar scores, identifying newborns that may need resuscitation procedures.Impact StatementWhat is already known on this subject? Adequate prenatal care and proper labour management are the main factors that reduce the risk of complications at birth. The Apgar score at the first minute of life reflects conditions during labour but it is not a parameter that indicates resuscitation procedures. Previous studies have reported the association Apgar score at five minutes of life with the neonatal outcome.What the results of this study add? This study identifies risk factors associated with an Apgar score ≤3 in the first minute of life in a tertiary referral hospital. Eclampsia was the greatest independent risk factor, increasing by 31 times the risk of having an Apgar score ≤3 in the first minute of life.What the implications are of these findings for clinical practice and/or further research? Identification of these risk factors, especially prompt treatment antenataly and during labour for hypertensive pregnant women, can prevent neonatal hypoxia and reduce the number of newborns that may need resuscitation procedures.

Missed opportunities in the prevention and diagnosis of pediatric tuberculosis: a scoping review.

OBJECTIVES: Identify potential barriers, delays, and missed opportunities in the prevention and diagnosis of childhood TB. METHODS: Scoping review according to the PRISMA extension. The definitions considered for the selection followed the acronym PCC where the population (P) is children under 18 years of age with TB disease, the concept (C) refers to missed opportunities for prevention and diagnosis, and context (C) is defined as a diagnosis of TB disease. The authors searched systematically in the databases; VHL/Lilacs, Medline via PubMed, Cochrane, Scopus, and Web of Science, without date or language limitation. RESULTS: Seven studies were included. In developed countries, with low disease burden, the main shortcoming is the delay in diagnosing bacilliferous adults in contact with young children. This problem is concentrated in the portion of the population with socioeconomic vulnerability. In underdeveloped countries, with a high burden of disease, the biggest challenge is tracking children who come into contact with bacilliferous patients. CONCLUSIONS: There are still many missed opportunities in the prevention and diagnosis of childhood TB. The positive legacy of the COVID-19 pandemic should be taken advantage of and the encouragement of scientific development in the management of infectious diseases should be taken.

Third stage of the kangaroo method: exclusive breastfeeding and growth of preterm and/or low birth weight newborns.

OBJECTIVE: To evaluate the rates of exclusive breastfeeding (EBF) and growth of preterm and/or low birth weight newborns during the third stage of the Kangaroo Method (TSKM), at discharge. METHODS: Retrospective study in a reference public maternity hospital between Jan/2014 and Dec/2017, including the preterm (less than 37 weeks) and/or low birth weight (less than 2500 g) newborn infants. Information was collected from medical records. Statistics analysis was done in SPSS software. RESULTS: 482 infants were included and followed up at the TSKM ambulatory. The average gestational age was 33 weeks (variation: 24-39 weeks) and birth weight, 1715g (variation: 455-2830 g). EBF occurred in 336 (70.1%) infants at hospital discharge, and in 291 (60.4%) at TSKM discharge. Each additional day of hospital stay increased the chance of infant formula (IF) use by 9.3% at hospital discharge and by 10.3% at TSKM discharge. Staying in the Kangaroo Neonatal Intermediate Care Unit (KNICU) favored EBF at hospital discharge and TSKM discharge (p<0.001). Not performing the kangaroo position increased the chance formula administration to the newborn infant at hospital discharge by 11%. Weight gain and head circumference growth were higher in infants using formula (p<0.001). CONCLUSIONS: The length of hospital stay and not performing the kangaroo position favored the use of infant formula at hospital and TSKM discharge. Staying in the KNICU favored exclusive breastfeeding at hospital and TSKM discharge. Weight gain and HC growth were higher in newborns receiving infant formula.

Bloodstream infection in pediatric patients with febrile neutropenia induced by chemotherapy.

INTRODUCTION: Febrile neutropenia (FN) is a serious complication of cancer chemotherapy. The present study aimed to identify risk factors for documented infection in pediatric patients with FN and cancer. METHODS: This prospective cohort study included patients under 18 years from 2016 to 2018. Infection was defined according to the Centers for Disease Control and Prevention criteria. RESULTS: A total of 172 febrile neutropenic episodes were evaluated. From univariate analysis, the risk factors were: female gender; monocyte count < 100 cell/mm³, platelets < 50,000, C-reactive protein (CRP) > 90 mg/dl and hemoglobin < 7mg/dl at the onset of an episode; two or more episodes of FN, and; fever onset; positive blood culture at the fever onset. Independent risk factors according to the multivariate analysis were: CRP at the onset of a febrile episode > 90mg/dl, fever onset and first blood culture with a positive result. The lowest probability of infection was related to first episode and to platelets > 50,000 at the onset of fever. CONCLUSION: A CRP > 90 at the onset of a febrile episode, platelets < 50,000, second episode or more, first fever episode during hospitalization and positive first blood culture were found to be associated with a higher risk of infection and they could be useful for the establishment of risk scores for infection in neutropenic children.

Respiratory distress syndrome prediction at birth by optical skin maturity assessment and machine learning models for limited-resource settings: a development and validation study.

Background: A handheld optical device was developed to evaluate a newborn's skin maturity by assessing the photobiological properties of the tissue and processing it with other variables to predict early neonatal prognosis related to prematurity. This study assessed the device's ability to predict respiratory distress syndrome (RDS). Methods: To assess the device's utility we enrolled newborns at childbirth in six urban perinatal centers from two multicenter single-blinded clinical trials. All newborns had inpatient follow-up until 72 h of life. We trained supervised machine learning models with data from 780 newborns in a Brazilian trial and provided external validation with data from 305 low-birth-weight newborns from another trial that assessed Brazilian and Mozambican newborns. The index test measured skin optical reflection with an optical sensor and adjusted acquired values with clinical variables such as birth weight and prenatal corticoid exposition for lung maturity, maternal diabetes, and hypertensive disturbances. The performance of the models was evaluated using intrasample k-parts cross-validation and external validation in an independent sample. Results: Models adjusting three predictors (skin reflection, birth weight, and antenatal corticoid exposure) or five predictors had a similar performance, including or not maternal diabetes and hypertensive diseases. The best global accuracy was 89.7 (95% CI: 87.4 to 91.8, with a high sensitivity of 85.6% (80.2 to 90.0) and specificity of 91.3% (95% CI: 88.7 to 93.5). The test correctly discriminated RDS newborns in external validation, with 82.3% (95% CI: 77.5 to 86.4) accuracy. Our findings demonstrate a new way to assess a newborn's lung maturity, providing potential opportunities for earlier and more effective care.

Gestational age assessed by optical skin reflection in low-birth-weight newborns: Applications in classification at birth.

Introduction: A new medical device was previously developed to estimate gestational age (GA) at birth by processing a machine learning algorithm on the light scatter signal acquired on the newborn's skin. The study aims to validate GA calculated by the new device (test), comparing the result with the best available GA in newborns with low birth weight (LBW). Methods: We conducted a multicenter, non-randomized, and single-blinded clinical trial in three urban referral centers for perinatal care in Brazil and Mozambique. LBW newborns with a GA over 24 weeks and weighing between 500 and 2,500 g were recruited in the first 24 h of life. All pregnancies had a GA calculated by obstetric ultrasound before 24 weeks or by reliable last menstrual period (LMP). The primary endpoint was the agreement between the GA calculated by the new device (test) and the best available clinical GA, with 95% confidence limits. In addition, we assessed the accuracy of using the test in the classification of preterm and SGA. Prematurity was childbirth before 37 gestational weeks. The growth standard curve was Intergrowth-21st, with the 10th percentile being the limit for classifying SGA. Results: Among 305 evaluated newborns, 234 (76.7%) were premature, and 139 (45.6%) were SGA. The intraclass correlation coefficient between GA by the test and reference GA was 0.829 (95% CI: 0.785-0.863). However, the new device (test) underestimated the reference GA by an average of 2.8 days (95% limits of agreement: -40.6 to 31.2 days). Its use in classifying preterm or term newborns revealed an accuracy of 78.4% (95% CI: 73.3-81.6), with high sensitivity (96.2%; 95% CI: 92.8-98.2). The accuracy of classifying SGA newborns using GA calculated by the test was 62.3% (95% CI: 56.6-67.8). Discussion: The new device (test) was able to assess GA at birth in LBW newborns, with a high agreement with the best available GA as a reference. The GA estimated by the device (test), when used to classify newborns on the first day of life, was useful in identifying premature infants but not when applied to identify SGA infants, considering current algohrithm. Nonetheless, the new device (test) has the potential to provide important information in places where the GA is unknown or inaccurate.

Psychometric properties of CVFQ7-BR-toxo to evaluate vision-related quality of life in children with congenital toxoplasmosis in Brazil.

PURPOSE: The high prevalence and severity of congenital toxoplasmosis in Brazil, with several affected individuals progressing to low vision, emphasize the importance of evaluating their quality of life. In this study, the Children's Visual Function Questionnaire (CVFQ) was adapted to the sociocultural context of Brazilian children, and its psychometric properties were investigated for evaluating the vision-related quality of life of these individuals. METHODS: This was a nested cross-sectional epidemiological study that prospectively monitored a cohort of 142 preschool children at a single referral university hospital in Belo Horizonte, Brazil. All children underwent complete ophthalmological examination, including visual acuity testing and binocular indirect ophthalmoscopy. Questionnaires were applied to their parents and caregivers to evaluate quality of life perception, as well as socioeconomic status of their families. Psychometric properties of the quality of life scale were evalua-ted by multivariate statistical analyses. RESULTS: Adaptation to the Brazilian version of CVFQ-7 resulted in CVFQ-BR-toxo, a questionnaire for evaluating the perception of parents/caregivers about the vision-related quality of life of preschool children with congenital toxoplasmosis. The following six subscales were identified based on description, variability structure, and interpretation/grouping of items: general health, visual acuity, visual performance/functional vision, personal and social behavior, impact on family, and treatment. Children with low vision related to congenital toxoplasmosis had significantly lower scores for the following subscales: visual acuity (p=0.004), visual performance/functional vision (p=0.008), impact on family (p=0.001), and overall health (p=0.001). CONCLUSION: Psychometric properties were appropriate concerning the validity of the quality of life construct. CVFQ-BR-toxo could demonstrate the impact of vision impairment on families of children with congenital toxoplasmosis.

Latent tuberculosis: Risk factors, screening and treatment in liver transplantation recipients from an endemic area.

BACKGROUND: Patients undergoing solid organ transplantation, particularly those who live or have lived in tuberculosis (TB) endemic areas, are at a high risk of developing TB. The majority of post-transplantation TB cases are associated with reactivation of latent TB infection (LTBI). Brazil is in a single position with overlapping areas of high TB endemicity and high transplant activity. In liver transplant (LT), one should be aware of the potential hepatotoxicity associated with the treatment regimens for LTBI. AIM: To evaluate the frequency of LTBI in LT patients and treatment-related issues. METHODS: This was a retrospective analysis of a cohort of cirrhotic patients aged ≥ 18 years, who underwent LT at a high-complexity teaching hospital from January 2005 to December 2012. RESULTS: Overall, 429 patients underwent LT during the study period. Of these, 213 (49.7%) underwent the tuberculin skin test (TST) during the pre-transplant period, and 35 (16.4%) of them had a positive result. The treatment for LTBI was initiated after LT in 12 (34.3%) of the TST-positive patients; in 3 (25.0%), treatment was maintained for at least 6 mo. CONCLUSION: The prevalence of LTBI was lower than expected. Initiation and completion of LTBI treatment was limited by difficulties in the management of these special patients.

DIAGNOSTIC VALUE OF THE REACTION AT THE BACILLUS CALMETTE-GUÉRIN VACCINATION SITE IN KAWASAKI DISEASE.

OBJECTIVE: To describe the case of an infant - diagnosed with incomplete Kawasaki disease - who developed BCG scar reactivation. CASE DESCRIPTION: A 6-month-old patient was admitted to hospital with fever associated with ocular hyperemia, cervical lymphadenopathy, and hyperemic lips, and remained hospitalized for 12 days. The physical examination revealed an inflammatory reaction at the site of the BCG scar, leading to the diagnosis of incomplete Kawasaki disease. The patient was treated with venous immunoglobulin, but presented recurrence of Kawasaki disease, with subsequent onset of coronary artery disease. COMMENTS: BCG scar reactivation is an important finding in countries where the vaccine is routinely given and may be a useful marker for early diagnosis of Kawasaki disease, especially in its incomplete form.

Hemophagocytic lymphohistiocytosis and visceral leishmaniasis in children: a series of cases and literature review.

OBJECTIVE: Hemophagocytic lymphohistiocytosis syndrome (HLHS) is characterized by an immunological hyperactivation of cytotoxic T cells, natural killer cells, and macrophages, leading to the secretion of proinflammatory cytokines. HLHS associated with Visceral Leishmaniasis might be difficult to diagnose once symptoms are similar, resulting in the death of untreated patients. Our aim is to describe a series of cases of Visceral Leishmaniasis with HLHS admitted to a referral hospital for infectious diseases. CASE DESCRIPTION: All 115 cases of Visceral Leishmaniasis referred to a referral center for pediatric infectious diseases were reviewed to identify the cases of HLHS. Five cases (4.5%) were confirmed with HLHS and they presented fever, splenomegaly, cytopenia, hypertriglyceridemia or hypofibrinogenemia, increased ferritin and hemophagocytosis in the bone marrow. COMMENTS: It important to rule out HLHS in children with infectious diseases that do not respond adequately to treatment or in patients with severe symptoms, especially in leishmaniasis endemic areas.

Antimicrobial use for treatment of healthcare-associated infections and bacterial resistance in a reference neonatal unit.

OBJECTIVE: The use of broad-spectrum antimicrobials, such as third and fourth-generation, are responsible for emergence of multidrug-resistant microorganisms in neonatal units. Furthermore, antimicrobial daily doses are not standardized in neonatology. This study aimed to investigate the association between the use of antimicrobial broad spectrum to bacterial sensitivity profile in a referral unit of neonatal progressive care. METHODS: This is a cohort study conducted in a referral neonatal progressive care unit from January 2008 to December 2016. The data of all hospitalized neonates was collected daily. The infection criteria used were the standardized national criteria, based on definitions of Center for Diseases Control and Prevention. In this study, the use of antimicrobials was evaluated as antimicrobial-day (ATM-day) and the ratio of multidrug-resistant microorganisms per 1000 ATM-day of broad spectrum was also calculated. The study was approved by the Institutional Review Board of the Universidade Federal de Minas Gerais (ETIC 312/08 e CAAE 58973616.2.0000.5149). RESULTS: From 2008 to 2016, 2751 neonates were hospitalized, corresponding to 60,656 patient-days. The ratio of multidrug-resistant microorganisms per 1000 ATM-day of broad spectrum was 1,3 in the first period and 4,3 in the second period (p=0,005). CONCLUSION: It was observed that use of broad-spectrum antimicrobials, especially those with coverage for Gram-negative bacteria, was associated with an increase of multidrug-resistant bacteria.

Clinical usefulness of catheter-drawn blood samples and catheter-tip cultures for the diagnosis of catheter-related bloodstream infections in neonates.

Catheter-drawn blood sampling is an efficient method of diagnosing catheter-related bloodstream infection (CRBSI) in neonates; it has greater sensitivity and accuracy than methods using catheter-tip cultures. No association was detected between catheter-drawn blood sampling and the occurrence of adverse events with central venous catheters.

Risk factors for central venous catheter-related bloodstream infection in neonates.

We found that low birth weight and type of central venous catheter were associated with catheter-related bloodstream infection in neonates. In the multivariate analysis, only central venous catheter type (dissected veins, tunneled catheters, and short-term nontunneled catheters) remained significantly associated with catheter-related bloodstream infection.

Yellow fever in children and adolescents previously immunized in Minas Gerais State, Brazil.

Background - Yellow fever (YF) is a viral hemorrhagic fever that is transmitted by arthropods. It can occur with little symptomatic manifestations to the most fulminant forms. The most effective way to avoid YF is through vaccination. There is a lack of information about the immune response of the vaccine in childhood. Methods - We described children and adolescents with YF who had been previously immunized in Minas Gerais State from July 2017 to June 2018. Results - 527 cases of YF were observed representing an incidence of 7.6/100,000 inhabitants. Only 26 patients (4.9%) were ≤ 20 years and 501 (95.1%) were > 20 years. Only 9 vaccinated patients were ≤ 20 years and 15 were > 20 years. 34.6% (9/26) of YF patients ≤ 20 years were previously vaccinated and 3% (15/501) of those > 20 years (p < 0.001). The median age at vaccination was 1 year between those ≤ 20 years and 31 years between those > 20 years (p = 0.002). Among 9 vaccinated children and adolescents ≤ 20 years, age ranged from 7 to 18 years, the most described symptoms were fever (88%), headache (77%), myalgia (77%), and abdominal pain (66%). All patients recovered from the disease and none died. Conclusion - Prior YF vaccination may be associated with mild forms of the disease in children and adolescents. YF vaccination in the first years of life may be associated with poor vaccine response and high infection rates in this group as it fail to seroconvert a significant proportion of infants.

Risk factors associated with the outcomes of pediatric bacterial meningitis: a systematic review.

OBJECTIVE: The aim of this study was to systematically review the literature and answer the following central question: "What are the risk factors associated with worse clinical outcomes of pediatric bacterial meningitis patients?" METHODS: The articles were obtained through literary search using electronic bibliographic databases: Web of Science, Scopus, MEDLINE, and LILACS; they were selected using the international guideline outlined by the Preferred Reporting Items for Systematic Reviews and Meta-analysis Protocols. RESULTS: The literature search identified 1,244 articles. After methodological screening, 17 studies were eligible for this systematic review. A total of 9,581 patients aged between 0 days and 18 years were evaluated in the included studies, and several plausible and important prognostic factors are proposed for prediction of poor outcomes after bacterial meningitis in childhood. Late diagnosis reduces the chances for a better evolution and reinforces the importance of a high diagnostic suspicion of meningitis, especially in febrile pictures with nonspecific symptomatology. S. pneumoniae as a causative pathogen was demonstrated to be related to clinical severity. CONCLUSIONS: Early prediction of an adverse outcome may help determine which children require more intensive or longer follow-up and may provide the physician with rationale for parental counseling about their child's prognosis in an early phase of the disease.

Diagnosis of pulmonary tuberculosis in children and adolescents: comparison of two versions of the Brazilian Ministry of Health scoring system.

The aim of this study was to evaluate the concordance between two versions of the scoring system (2011 and 2019), recommended by the Brazilian Ministry of Health, for the diagnosis of pulmonary tuberculosis (PTB) in children and adolescents. A retrospective descriptive study was performed to assess the medical records of children and adolescents with PTB, in TB units from Brazilian cities located in Rio de Janeiro, Minas Gerais, and Parana States, from January 1 st , 2004, to December 1 st , 2018. Patients aged 0 to 18 years old with a diagnosis of PTB were included. The comparison between the two scoring systems showed a moderate concordance according to the κ coefficient value = 0.625. Fourteen patients showed a reduction in the TB score, going from 30 points in the 2011, to 25 points or less in the 2019 one. Seventy one percent of these 14 patients had radiological changes suggestive of PTB and 86% had tuberculin skin tests greater than 10 mm. The study concluded that a moderate agreement was observed between the 2011 and 2019 scoring systems, with an increase in the number of patients scoring 25 points or less in 2019, which can eventually hinder the diagnosis of PTB.

Neurological manifestations of pediatric arboviral infections in the Americas.

Dengue, Zika, Chikungunya and yellow fever viruses are arboviruses transmitted by the mosquito Aedes aegypti. These viruses exhibit marked neurotropism but have rarely been studied. Here, we conduct an integrative review of the neurological manifestations caused by these arboviruses in the pediatric population. Data on patients under 18 years of age were extracted from literature databases. The most frequently reported neurological manifestations were encephalitis, meningitis, seizures, hypotonia, paresis, and behavioral changes. This review highlights the importance of accurately diagnosing these arboviral infections in children and adolescents with neurological manifestations.

Third stage of the kangaroo method: exclusive breastfeeding and growth of preterm and/or low birth weight newborns / Terceira etapa do método canguru: aleitamento materno exclusivo e crescimento de recém-nascidos pré-termo e/ou de baixo peso ao nascer

Objective: To evaluate the rates of exclusive breastfeeding (EBF) and growth of preterm and/or low birth weight newborns during the third stage of the Kangaroo Method (TSKM), at discharge. Methods: Retrospective study in a reference public maternity hospital between Jan/2014 and Dec/2017, including the preterm (less than 37 weeks) and/or low birth weight (less than 2500 g) newborn infants. Information was collected from medical records. Statistics analysis was done in SPSS software. Results: 482 infants were included and followed up at the TSKM ambulatory. The average gestational age was 33 weeks (variation: 24-39 weeks) and birth weight, 1715g (variation: 455-2830 g). EBF occurred in 336 (70.1%) infants at hospital discharge, and in 291 (60.4%) at TSKM discharge. Each additional day of hospital stay increased the chance of infant formula (IF) use by 9.3% at hospital discharge and by 10.3% at TSKM discharge. Staying in the Kangaroo Neonatal Intermediate Care Unit (KNICU) favored EBF at hospital discharge and TSKM discharge (p<0.001). Not performing the kangaroo position increased the chance formula administration to the newborn infant at hospital discharge by 11%. Weight gain and head circumference growth were higher in infants using formula (p<0.001). Conclusions: The length of hospital stay and not performing the kangaroo position favored the use of infant formula at hospital and TSKM discharge. Staying in the KNICU favored exclusive breastfeeding at hospital and TSKM discharge. Weight gain and HC growth were higher in newborns receiving infant formula.

RESUMO Objetivo: Avaliar as taxas de aleitamento materno exclusivo e o crescimento dos recém-nascidos (RN) pré-termo e/ou de baixo peso ao nascer à alta da terceira etapa do Método Canguru (TEMC). Métodos: Estudo retrospectivo realizado em maternidade pública de referência entre janeiro/2014 e dezembro/2017, que incluiu os RN pré-termo (<37 semanas) e/ou de baixo peso (<2.500 g). As informações foram coletadas de prontuários médicos e analisadas pelo programa Statistical Package for the Social Sciences (SPSS). Resultados: Foram seguidos 482 RN, com mediana da idade gestacional de 33 semanas (variação: 24-39 sem) e peso ao nascer 1.715 g (variação: 455-2.830 g). O aleitamento materno exclusivo (AME) ocorreu em 336 (70,1%) RN à alta hospitalar e em 291 (60,4%) à alta da TEMC. Cada dia a mais de permanência hospitalar aumentou a chance do uso de fórmula infantil em 9,3% à alta hospitalar e em 10,3% à alta da TEMC. Permanecer na Unidade de Cuidados Intermediários Canguru (UCINCA) favoreceu o AME à alta hospitalar e da TEMC (p<0,001). Não realizar a Posição Canguru aumentou em 11% a chance de o RN utilizar fórmula infantil à alta hospitalar. O ganho de peso e crescimento do perímetro cefálico foram maiores nos RN em uso de fórmula infantil (p<0,001). Conclusões: O tempo de permanência hospitalar e a não realização da Posição Canguru favoreceram o uso de fórmula infantil à alta hospitalar e da TEMC. Permanecer na UCINCA favoreceu o AME à alta hospitalar e da TEMC. O ganho de peso e crescimento do PC foram maiores nos RN em uso de fórmula infantil.
