ABSTRACT Objective: To verify the use and identify advantages of molecular methods for congenital infections diagnosis in cerebrospinal fluid of neonates. Data source: The review was registered in the International Prospective Register of Systematic Reviews (PROSPERO), under CRD42021274210. The literature search was performed in databases: PubMed, Virtual Health Library/ Latin American and Caribbean Center on Health Sciences Information (VHL/BIREME), Scopus, Web of Science, Excerpta Medica database (EMBASE), Cochrane, ProQuest, and EBSCOhost. The search was carried out from August to October 2021 and updated in December 2022, respecting the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines. The selection sequence was: 1) Duplicate title removal; 2) Examination of titles and abstracts; 3) Full-text retrieval of potentially relevant reports; and 4) Evaluation of the full text according to eligibility criteria by two independent authors. Inclusion criteria considered randomized and non-randomized control trials, longitudinal, cross-sectional, and peer-reviewed studies in humans, published in English, Spanish, Italian, and Portuguese, with newborns up to 28 days old who had congenital neuroinfections by toxoplasmosis, rubella, cytomegalovirus, herpes simplex (TORCH), and others such as Treponema pallidum, Zika, parvovirus B-19, varicella zoster, Epstein-Barr, and SARS-CoV2, diagnosed by polymerase chain reaction (PCR). Two evaluators extracted the following information: author, year of publication, nationality, subjects, study type, methods, results, and conclusion. Data synthesis: The most studied pathogen was herpes simplex. Several articles reported only nonspecific initial symptoms, motivating the collection of cerebrospinal fluid and performing PCR for etiological investigation. Conclusions: Molecular methods are effective to detect pathogen genomes in cerebrospinal fluid, which can impact clinical evolution and neurological prognosis.

Resumen A pesar de los beneficios bien conocidos de la anestesia raquídea (AR), esta técnica sigue siendo subutilizada entre los anestesiólogos pediátricos. De acuerdo con los datos de la Red Regional de Anestesia Pediátrica, la AR representó menos del 5% de todas las técnicas neuroaxiales. Algunos de los factores a los que se atribuye dicha subutilización son: su duración limitada, la falta de familiaridad con la técnica en niños de menor edad, y la preferencia del anestesiólogo por la anestesia general. El uso seguro y exitoso de la AR en niños implica el claro conocimiento de las diferencias anatómicas y fisiológicas entre adultos y niños, en virtud de las diferencias en las estructuras óseas, el crecimiento de la médula espinal y la fisiología del líquido cefalorraquídeo. Los reportes sobre el uso exitoso de la AR en niños para diferentes cirugías ha aumentado. La presente revisión educativa resumen la información conocida sobre AR en niños, revisiones de la literatura de la última década y ofrece sugerencias para el desarrollo de la AR en población pediátrica. Se discuten consideraciones técnicas, el papel de la ecografía, orientación sobre la dosificación, los efectos fisiológicos, aspectos no explicados del mecanismo de acción y la combinación de anestesia raquídea/caudal.

Abstract Despite the well-known benefits of spinal anesthesia (SA), this technique remains underutilized among pediatric anesthesiologists. According to the data from the Pediatric Regional Anesthesia Network, SA accounted for less than 5% of all neuraxial techniques. Some of the factors for underutilization of SA include: Limited duration, unfamiliarity with the technique in younger children, and surgeon preference for general anesthesia. The safe and successful use of SA in children involves recognition of anatomical and physiological differences between adults and children owing to differences in bony structures, spinal cord growth and cerebrospinal fluid physiology. Reports on successful use of SA in children for various surgeries have increased. This educational review summarizes what is known about SA in children, reviews the literature from the last decade and provides suggestions for development of SA in children. Technical considerations, role of ultrasound, guidance on dosing, physiological effects, unexplained aspects of the mechanism of action and combined caudal/SA are discussed.

Abstract Background: Patent Ductus Arteriosus (PDA) is the most common congenital heart disease, particularly prevalent among preterm newborns (PTNB) and those with low birth weight. Surgical closure is traditionally considered after the failure of pharmacological treatment. The aim was to analyze the immediate and long-term outcomes of surgical PDA closure in PTNB. Methods: This analytical study evaluated PTNB who underwent PDA surgery between January 2002 and December 2023 at the Hospital Clínico Regional “Dr. Guillermo Grant Benavente” in Concepción, Chile. The databases were reviewed with prior approval from the Ethical-Scientific Committee. PTNB were defined as those with a gestational age (GA) of less than 37 weeks. Data analysis was performed using SPSS® v29, and survival rates were graphed using the Kaplan-Meier method. Results: Since 1993, a total of 263 cases have been recorded in the PDA protocol registry. During the study period, 167 cases were identified, of which 131 (78.3%) were PTNB. Among them, 65 (49.6%) were male. The average GA was 26.4±2.3 weeks and the average birth weight was 900±348 grams. Pharmacological treatment failed in all cases included. At the time of surgery, the average age was 35.0±43.2 days, and the average weight was 1,443±1,716 grams. A left posterolateral thoracotomy with an extrapleural approach and primary closure with clips was performed. Immediate complications included post-ligation syndrome in 42 (32.1%) cases and atelectasis in 14 (10.7%) cases. There was no intraoperative mortality. The 30-day mortality rate was 15 (11.5%) cases. The 10-year survival rate was 82.4%. Conclusion: Clipping is the preferred technique at our center and has shown results comparable to other series. Mortality was mainly due to medical comorbidities such as sepsis and respiratory tract immaturity.

Resumen Antecedentes: El Ductus Arterioso Persistente (DAP) es la cardiopatía congénita más frecuente. Es más prevalente en recién nacidos de pretérmino (RNPT) y bajo peso al nacer. El cierre quirúrgico está indicado tradicionalmente tras el fracaso del cierre farmacológico. El objetivo es analizar los resultados inmediatos y alejados del cierre quirúrgico del DAP en RNPT. Métodos: Estudio analítico de RNPT operados por DAP en el período desde enero-2002 y diciembre-2023 en el Hospital Clínico Regional “Dr. Guillermo Grant Benavente”, Concepción-Chile. Se revisaron bases de datos previa aprobación de Comité Ético-Científico. Se consideró RNPT <37 semanas de edad gestacional (EG). Se utilizó SPSS® v29, se graficó supervivencia mediante método de KaplanMeier. Resultados: En el período de análisis hubo 167 casos, de es de los cuales 131 (78,3%) eran RNPT. Fueron hombres 65 (49,6%) y la edad gestacional (EG) promedio fue 26,4±2,3 semanas, con peso al nacer de 900±348 gramos. Todos los casos tuvieron tratamiento farmacológico previo. Al momento de la cirugía, la edad promedio era 35,0±43,2 días y el peso promedio 1.443±1.716 gramos. Se realizó una toracotomía posterolateral izquierda, con abordaje extrapleural y cierre principalmente mediante clipaje. Las complicaciones inmediatas fueron: síndrome post ligadura en 42 (32,1%) y atelectasia en 14 (10,7%). No hubo mortalidad intraoperatoria. A 30 días post cirugía fallecieron 15 casos, (11,5%) La supervivencia a 10 años fue 82,4%. Conclusiones: El cierre mediante clipaje es la técnica de elección en nuestro centro y demostró resultados comparables a diferentes series incluidas en la discusión. La mortalidad fue debida principalmente a comorbilidades médicas como sepsis e inmadurez del tracto respiratorio.

ABSTRACT: This study determined the zootechnical, metabolic, and health performance of Girolando calves born with high or low birth weight, conceived through in vitro fertilization. The study was carried out on a commercial dairy farm located in Passos, Minas Gerais, Brazil. For this, a hundred Girolando calves were divided into two groups: The Control, which consisted of calves that were born weighing ≤ 35 kg; and high birth weight (HBW) calves, which were born weighing > 35 kg. The calves were monitored for zootechnical parameters; epidemiological indices, for diseases such diarrhea and pneumonia; as well as serum concentrations of aspartate aminotransferase, alanine aminotransferase, alkaline phosphatase, gamma-glutamyl transferase, cholesterol, triglycerides, paraoxonase1, albumin, urea, and globulin. Calves from the HBW group had a higher general mortality rate, but no effects on the zootechnical performance or metabolism were observed. The results obtained allow us to conclude that Girolando calves generated by IVF and heavier at birth have a greater chance to present diseases such as omphalophlebitis, tympany, and bovine parasitic sadness, and have a higher rate of general mortality. Conversely, birth weight of the calves does not influence diarrhea or pneumonia, the zootechnical performance, or the metabolism.

RESUMO: Este estudo determinou o desempenho zootécnico, metabólico e saúde de bezerras Girolando nascidas com alto ou baixo peso, concebidas por fertilização in vitro. O estudo foi realizado em uma fazenda leiteira comercial localizada em Passos, Minas Gerais, Brasil. Cem bezerras Girolando foram divididas em dois grupos: Controle, que consistiu em bezerras que nasceram com peso ≤ 35 kg; e HBW, bezerras que nasceram com peso > 35 kg. As bezerras foram monitoradas quanto aos parâmetros zootécnicos; índices epidemiológicos para doenças como diarreia e pneumonia; bem como as concentrações séricas de aspartato aminotransferase, alanina aminotransferase, fosfatase alcalina, gama-glutamil transferase, colesterol, triglicérides, paraoxonase1, albumina, uréia e globulina. As bezerras do grupo HBW apresentaram maior taxa de mortalidade, mas nenhum efeito no desempenho zootécnico ou metabolismo foram observados. Os resultados permitem concluir que bezerras Girolando provenientes de FIV que nascem mais pesadas têm maior chance de apresentar doenças, como onfaloflebite, timpanismo e tristeza parasitária bovina, tendo uma maior taxa de mortalidade geral. Porém, o peso ao nascimento das bezerras não influenciou a ocorrência de diarreia ou broncopneumonia, o desempenho zootécnico e o perfil metabólico.

Abstract: Congenital Central Hypoventilation Syndrome (CCHS) is a rare genetic condition affecting the autonomic nervous system and respiratory center due to mutations in the PHOX2B gene, and it is associated with alveolar hypoventilation during sleep and sudden death. It requires early invasive mechanical ventilation (IMV). Objective: To report a neonatal case successfully treated with non-invasive ventilatory support (NVS), avoiding tracheostomy. Clinical Case: Full-term newborn, whose mother uses nocturnal NVS due to CCHS. During the transition period, she presented desaturations associated with hypercapnia and respiratory acidosis, without pulmonary involvement. She developed severe hypoventilation during sleep, with no respiratory effort, peripheral oxygen saturation (SpO2) < 80%, plus respiratory acidosis. While awake, she had good respiratory effort and normal SpO2 without assistance. Noninvasive continuous positive airway pressure and oxygen therapy worsened her condition while sleeping. Complete NVS with nasal interface and bi-level airway positive pressure, inspiratory/expiratory pressure 14-16/4 cm H2O, normalized SpO2 during sleep, and arterial blood gases while awake. Sequencing of the PHOX2B gene confirmed the presence of a heterozygous pathogenic variant with the 20/26 genotype. At 2 months of age, she was discharged maintaining NVS with nasal interface and 0 PEEP, achieving adequate neurodevelopment. Conclusion: We highlight the importance of genetic diagnosis of CCHS in neonates with clinical presentation of early alveolar hypoventilation, especially if there is a family history. We are not aware of other reports of neonatal onset in which NVS prevents IMV, in this potentially lethal pathology.

Resumen: El Síndrome de Hipoventilación Central Congénito (SHCC) es una condición genética infrecuente que afecta el sistema nervioso autónomo y centro respiratorio por mutaciones en el gen PHOX2B, se asocia a hipoventilación alveolar durante el sueño y muerte súbita. Requiere tempranamente de ventilación mecánica invasiva (VMI). Objetivo: Reportar un caso neonatal tratado exitosamente con soporte ventilatorio no invasivo (SVNI), evitando la traqueostomía. Caso Clínico: Recién nacido de término, cuya madre utiliza SVNI nocturno por SHCC. Durante el periodo de transición presentó desaturaciones asociadas a hipercapnia y acidosis respiratoria, sin compromiso pulmonar. Evolucionó con hipoventilación severa durante el sueño, sin esfuerzo respiratorio, saturación periférica de oxígeno (SpO2) < 80%, más acidosis respiratoria. En vigilia presentaba buen esfuerzo respiratorio y SpO2 normales sin asistencia. La presión positiva continua no invasiva en la vía aérea y la oxigenoterapia empeoraban su condición al dormir. El SVNI completo con interfaz nasal y presión positiva en 2 niveles, presión inspiratoria/espiratoria 14-16/4 cm H2O, normalizaron la SpO2 durante el sueño y los gases en sangre arterial en vigilia. La secuenciación del gen PHOX2B confirmó la presencia de una variante patogénica heterocigota con el genotipo 20/26. A los 2 meses de vida egresó manteniendo SVNI con interfaz nasal y PEEP 0, logrando neurodesarrollo adecuado. Conclusión: Resaltamos la importancia del diagnóstico genético del SHCC, en neonatos con presentación clínica de hipoventilación alveolar temprana, particularmente si existe el antecedente familiar. No conocemos otros reportes de debut neonatal en que el SVNI evite la VMI, en esta patología potencialmente letal.

ABSTRACT Foundation: atherosclerosis is a disease of multifactorial origin that is aggravated as a result of an adverse environment and unhealthy lifestyles. Evidence confirms its onset from the earliest stages of life. Objective: to describe the presence of early atherosclerotic lesions in the aortas of deceased fetuses and neonates born to hypertensive mothers. Method: a descriptive cross-sectional study was carried out that included fetuses older than 22 weeks and deceased neonates born to hypertensive mothers, who underwent autopsy in the pathological anatomy department of the Eusebio Hernández Pérez Gynecobstetric University Hospital, in the period between January 2021 and December 2022, with a total of 18. The following data were collected in the medical records: sex of the deceased, gestational age at the time of delivery, postpartum weight, maternal age, and history of arterial hypertension (chronic or gestational). The 18 aortas (thoracic and abdominal) of the selected deceased were analyzed. Results: of the total number of deceased studied, 70.6 % presented early atherosclerotic lesions, characterized by thickening of the intima as a cushion, presence of lymphocytes in the intima or in the arterial wall close to it and/or macrophages. In some cases, one of these histological variants was observed and in others a combination of two or three. Conclusions: early atherosclerotic lesions are present in the aortas of the majority of the fetuses and neonates studied, with a predominance in those with gestational hypertension.

RESUMEN Fundamento: la aterosclerosis es una enfermedad de origen multifactorial que se agrava a consecuencia de un medio ambiente adverso y de estilos de vida no saludables. Las evidencias confirman su inicio desde las etapas más tempranas de la vida. Objetivo: describir la presencia de lesiones ateroscleróticas tempranas en las aortas de fetos y neonatos fallecidos hijos de madres hipertensas. Método: se realizó un estudio descriptivo de tipo transversal que incluyó a los fetos mayores de 22 semanas y neonatos fallecidos hijos de madres hipertensas, a quienes se les realizó autopsia en el departamento de anatomía patológica, del Hospital Universitario Ginecobstétrico Eusebio Hernández Pérez, en el período comprendido entre enero del 2021 hasta diciembre 2022, con un total de 18. Se recogieron los siguientes datos en las historias clínicas: sexo del fallecido, edad gestacional en el momento del parto, peso postparto, edad materna y antecedentes de hipertensión arterial (crónica o gestacional). Se analizaron las 18 aortas (torácicas y abdominales) de los fallecidos seleccionados. Resultados: del total de fallecidos estudiados el 70,6 % presentó lesiones ateroscleróticas tempranas, caracterizadas por engrosamiento de la íntima a modo de cojinete, presencia de linfocitos en la íntima o en la pared arterial cercana a ella y/o macrófagos. En algunos casos se observó una de estas variantes histológicas y en otros la combinación de dos o tres. Conclusiones: las lesiones ateroscleróticas tempranas están presentes en las aortas de la mayoría de los fetos y neonatos estudiados, con predominio en las que presentaban hipertensión gestacional.

RESUMEN Objetivo: Estimar la frecuencia de la hemorragia intraventricular y los factores asociados en neonatos pretérmino hospitalizados en una unidad de cuidado intensivo neonatal de alta complejidad. Metodología: Estudio de cohorte, en el que se incluyeron neonatos menores de 37 semanas de gestación, atendidos en una institución de alta complejidad, entre enero de 2015 hasta diciembre de 2018; se valoró el desarrollo de hemorragia intraventricular diagnosticada por métodos de imagen. Los datos se obtuvieron a partir de la revisión de las historias clínicas electrónicas y se analizaron variables sociodemográficas y clínicas. Resultados: Se incluyeron 296 pacientes, 128 (43,2%) eran mujeres; 23 pacientes (7,8%) desarrollaron hemorragia intraventricular, la cual predominó en el sexo femenino (11,7%). La mediana de edad gestacional fue de 34 semanas. Los factores asociados al desarrollo de hemorragia intraventricular fueron el peso al nacer por debajo de 1500 gr, las infecciones (p<0,0001), los cuadros de apneas (<0,0001), la hiperglicemia (p = 0,025) y la necesidad de surfactante (p= 0,019); por su parte, los esteroides prenatales se comportaron como un factor protector (p=0,002). Los pacientes con hemorragia intraventricular tuvieron mayor necesidad de ventilación mecánica, mayor uso de inotrópicos o vasopresores, más transfusiones y mayor estancia hospitalaria. Conclusiones: A pesar de que la hemorragia intraventricular resultó ser una patología poco frecuente en la población de neonatos analizada, existen factores de riesgo que se relacionan con su desarrollo, como la edad gestacional, el bajo peso al nacer, las infecciones, las apneas y la hiperglicemia.

ABSTRACT Objective: Estimate the frequency of intraventricular hemorrhage and associated factors in hospitalized preterm infants in a highly complex neonatal intensive care unit. Methodology: Cohort study, which included neonates younger than 37 weeks gestation, attended in a highly complex institution, between January 2015 and December 2018; The development of intraventricular hemorrhage diagnosed by imaging methods was assessed. The data was obtained from the review of the electronic medical records and sociodemographic and clinical variables were analyzed. Results: 296 patients were included, 128 (43.2%) were women; 23 patients (7.8%) developed intraventricular hemorrhage, which predominated in the female sex (11.7%). The median gestational age was 34 weeks. The factors associated with the development of intraventricular hemorrhage were birth weight below 1500 gr, infections (p <0.0001), apnea symptoms (<0.0001), hyperglycemia (p = 0.025) and surfactant requirement (p = 0.019); meanwhile, prenatal steroids behaved as a protective factor (p = 0.002). Patients with intra-ventricular hemorrhage had a greater need for mechanical ventilation, use of inotropics or vasopressors, more transfusions, and a longer hospital stay. Conclusions: Despite the fact that intraventricular hemorrhage turned out to be a rare pathology in the analyzed neonatal population, there are risk factors related to its development, such as gestational age, low birth weight, infections, apneas, and hyperglycemia.

Abstract Introduction. Metabolic bone disease of premature infants is a rare complication characterized by a lower mineral content in bone tissue. Objective. To establish the incidence of metabolic bone disease in premature infants and to determine associated risk factors. Materials and method. We conducted a descriptive prospective cohort study for one year in all newborns under 32 gestational weeks, or 1,500 g, at the Hospital Universitario de Santander to determine the incidence of metabolic bone disease. We collected demographic data and prenatal histories of the selected patients, and later, we measured serum alkaline phosphatase and serum phosphorus at the third week of birth, having as reference values for diagnosis less than 5.6 mg/dl for the first one and more than 500 UI/L for the second one. We applied statistical tools for data analysis, such as average proportions, dispersion, distribution and association measures, and binomial regression. Results. From a total of 58 patients, 7 had a diagnosis of metabolic bone disease, with an incidence of 12%. The weight was reported as an independent variable for the development of the disease, being significant in children under 1,160 g, as well as prolonged parenteral nutrition for more than 24 days. When performing the multivariate analysis, low weight and short time of parenteral nutrition appeared as risk factors; in the same way, maternal age below 22 years is associated with a higher relative risk, even more than a newborn weight inferior to 1,160 g. Conclusion. Establishing an early intervention in patients with metabolic bone disease enhancing risk factors, such as low weight and prolonged parenteral nutrition, is critical to prevent severe complications.

Resumen Introducción. La enfermedad metabólica ósea de neonatos prematuros es una complicación poco común que se caracteriza por una disminución del contenido mineral en el hueso. Objetivo. Establecer la incidencia de la enfermedad metabólica ósea en neonatos prematuros y los factores de riesgo asociados. Materiales y métodos. Durante un año, se realizó un estudio prospectivo de cohorte, descriptivo, con todos los neonatos nacidos con menos de 32 semanas de gestación o un peso menor de 1.500 g en el Hospital Universitario de Santander. Se recolectaron datos demográficos y antecedentes prenatales de los pacientes seleccionados. A la tercera semana de nacimiento, se midieron la fosfatasa alcalina y el fósforo sérico, tomando como valores de referencia diagnóstica aquellos inferiores a 5,6 mg/dl para el primero y aquellos mayores de 500 UI/L para la segunda. Para el análisis de la información, se emplearon herramientas estadísticas, como proporciones de promedios, medidas de dispersión, distribución y asociación, y regresión binomial. Resultados. De un total de 58 pacientes, 7 tuvieron diagnóstico de enfermedad metabólica ósea, con una incidencia del 12 %. De las variables estudiadas, el peso se reportó como una variable independiente para el desarrollo de la enfermedad, significativa en aquellos neonatos con peso menor de 1.160 g, al igual que la nutrición parenteral prolongada por más de 24 días. Al hacer el análisis multivariado, La edad materna menor de 22 años representó un riesgo relativo mayor, en comparación con un peso inferior a 1.160 g. Conclusión. Se estableció la importancia de una intervención temprana en pacientes con factores de riesgo para enfermedad metabólica ósea, como bajo peso (menor de 1.160 g) y nutrición parenteral prolongada (mayor de 24 días), con el fin de prevenir complicaciones graves.

Abstract: Clinical control and monitoring of bilirubin in the neonatal stage are essential to avoid toxicity in the central nervous system. Objective: to determine the correlation between transcutaneous bilirubin (TcB) and total serum bilirubin (TSB) levels in newborns ≥ 35 weeks. Patients and Method: observational, cross-sectional, analytical, retrospective study that included 90 neonates of gestational age ≥ 35 weeks with mucocutaneous jaundice who underwent TcB and TSB measurement simultaneously between June 1, 2022, and January 31, 2023. Both variables were compared, determining their correlation. Results: the validity indicators were analyzed, obtaining 100% sensitivity and negative predictive value. The mean of TcB determinations was 14.84 mg/dl ± 2.27 and that of TSB was 13.1 mg/dl ± 2.39. The correlation obtained indicates that both variables are related, which is a direct correlation and, according to the prediction equation, there is an appropriate correlation between them. It was determined that TcB overestimated TSB in 95.56% of the determinations, and underestimated TSB in the rest (4.44%). Simultaneous measurements of TcB and TSB were different in all determinations with a mean difference of 1.72 ± 1.48. Conclusions: the non-invasive TcB method can be used as an initial screening tool for the neonatal population ≥ 35 weeks, given its adequate sensitivity and negative predictive value.

Resumen: El control clínico y la monitorización de la bilirrubina en la etapa neonatal son fundamentales para evitar la toxicidad sobre el sistema nervioso central. Objetivo: determinar la correlación entre las cifras de bilirrubina transcutánea (BTC) y bilirrubina sérica total (BST) en recién nacidos ≥ 35 semanas. Pacientes y Método: estudio observacional, transversal, analítico y retrospectivo que incluyó a 90 neonatos de edad gestacional ≥ 35 semanas e ictericia mucocutánea a los que se les realizó BTC y simultáneamente BST, entre el 1 de junio de 2022 y el 31 de enero de 2023. Se compararon ambas variables y se determinó su correlación. Resultados: se analizaron los indicadores de validez obteniendo una sensibilidad y valor predictivo negativo de 100%. La media de las determinaciones de BTC fueron de 14,84 mg/dl ± 2,27 y la de BST de 13,1 mg/dl ± 2,39. La correlación obtenida indica que ambas variables están relacionadas siendo ésta una correlación directa y en función de la ecuación de predicción se manifiesta una apropiada correlación entre ambas. Se determinó que la BTC sobreestima en el 95,56% de las determinaciones la BST, e infraestima en el resto (4,44%). Las mediciones simultáneas de BTC y BST fueron distintas en todas las determinaciones con una media de las diferencias de 1,72 ± 1,48. Conclusiones: el método no invasivo BTC puede utilizarse como herramienta de cribado inicial para la población neonatal ≥ 35 semanas, dada la adecuada sensibilidad y valor predictivo negativo.

ABSTRACT Objective: The aim was to identify the factors linked to jaundice that necessitates phototherapy. Material and Methods: An observational, analytical, and retrospective case-control study was conducted. The medical records of 212 patients aged 0 to 7 days from the neonatology service at Hospital Carlos Lanfranco La Hoz were reviewed, divided into 106 cases (with phototherapy) and 106 controls (without phototherapy). Results: Preterm neonates showed a significant association with an OR: 5.526; 95% CI (2.038-14.981), P= 0.001; and ABO incompatibility had an OR: 4.373, 95% CI (1.934-9.889), P= 0.001. Conclusions: The study concludes an association between preterm neonates, ABO incompatibility, and the necessity for phototherapy.

Resultados: Se encontró una asociación significativa entre los neonatos pretérmino y la necesidad de fototerapia, con un OR:5.526; IC 95% (2.038-14.981), P= 0.001; así como una asociación entre la incompatibilidad ABO y la fototerapia, con un OR:4.373, IC 95% (1.934-9.889), P= 0.001. Conclusiones: Se concluye que existe asociación entre neonatos pretérmino, la incompatibilidad ABO con la necesidad de fototerapia.

Resumen: El control clínico y la monitorización de la bilirrubina en la etapa neonatal son fundamentales para evitar la toxicidad sobre el sistema nervioso central. Objetivo: determinar la correlación entre las cifras de bilirrubina transcutánea (BTC) y bilirrubina sérica total (BST) en recién nacidos ≥ 35 semanas. Pacientes y Método: estudio observacional, transversal, analítico y retrospectivo que incluyó a 90 neonatos de edad gestacional ≥ 35 semanas e ictericia mucocutánea a los que se les realizó BTC y simultáneamente BST, entre el 1 de junio de 2022 y el 31 de enero de 2023. Se compararon ambas variables y se determinó su correlación. Resultados: se analizaron los indicadores de validez obteniendo una sensibilidad y valor predictivo negativo de 100%. La media de las determinaciones de BTC fueron de 14,84 mg/dl ± 2,27 y la de BST de 13,1 mg/dl ± 2,39. La correlación obtenida indica que ambas variables están relacionadas siendo ésta una correlación directa y en función de la ecuación de predicción se manifiesta una apropiada correlación entre ambas. Se determinó que la BTC sobreestima en el 95,56% de las determinaciones la BST, e infraestima en el resto (4,44%). Las mediciones simultáneas de BTC y BST fueron distintas en todas las determinaciones con una media de las diferencias de 1,72 ± 1,48. Conclusiones: el método no invasivo BTC puede utilizarse como herramienta de cribado inicial para la población neonatal ≥ 35 semanas, dada la adecuada sensibilidad y valor predictivo negativo.

Abstract: Clinical control and monitoring of bilirubin in the neonatal stage are essential to avoid toxicity in the central nervous system. Objective: to determine the correlation between transcutaneous bilirubin (TcB) and total serum bilirubin (TSB) levels in newborns ≥ 35 weeks. Patients and Method: observational, cross-sectional, analytical, retrospective study that included 90 neonates of gestational age ≥ 35 weeks with mucocutaneous jaundice who underwent TcB and TSB measurement simultaneously between June 1, 2022, and January 31, 2023. Both variables were compared, determining their correlation. Results: the validity indicators were analyzed, obtaining 100% sensitivity and negative predictive value. The mean of TcB determinations was 14.84 mg/dl ± 2.27 and that of TSB was 13.1 mg/dl ± 2.39. The correlation obtained indicates that both variables are related, which is a direct correlation and, according to the prediction equation, there is an appropriate correlation between them. It was determined that TcB overestimated TSB in 95.56% of the determinations, and underestimated TSB in the rest (4.44%). Simultaneous measurements of TcB and TSB were different in all determinations with a mean difference of 1.72 ± 1.48. Conclusions: the non-invasive TcB method can be used as an initial screening tool for the neonatal population ≥ 35 weeks, given its adequate sensitivity and negative predictive value.

Abstract Infections caused by Candida spp. are frequent in critically hospitalized patients, especially among premature neonates, representing one of the most common healthcare-related infections. Although there is considerable production of current knowledge about the mechanisms of immune response, aspects involved in the newborn's innate defense are not fully understood. The aim of this study was to describe the innate immune mechanisms involved in the defense of neonates against invasive candidiasis. This is an integrative literature review from the Scopus, Scifinder, Medline, Web of Science databases and the electronic libraries ScienceDirect and Scielo, in the period between 2002 and 2020, with rescue based on primary descriptor Immunity Innate plus secondary descriptors Candidiasis Invasive AND Infant Newborn. We have observed the involvement of various mechanisms in the neonatal response against invasive candidiasis, including the recognition, signaling, recruitment, and initiation of an effective immune response. These mechanisms encompass the presence of antimicrobial peptides, phagocytosis, synthesis of reactive oxygen species, inflammatory mediators, and complex cell signaling systems mediated by Pattern Recognition Receptors (PRRs). With this study, it is expected to contribute to the expansion of knowledge about the immunological mechanisms involved in the innate immune response of the newborn against disseminated infections caused by Candida species, and in the same sense, highlight the importance of this knowledge as a reflex in the decrease in mortality in the neonatal period. spp patients healthcarerelated healthcare related newborns s understood candidiasis Scopus Scifinder Medline Scielo 200 2020 Newborn recognition recruitment peptides phagocytosis species mediators PRRs.

Resumo As infecções causadas por Candida spp. são frequentes em pacientes hospitalizados em estado crítico, especialmente entre neonatos prematuros, representando uma das infecções relacionadas à assistência à saúde mais comuns. Embora haja considerável produção de conhecimento atual sobre os mecanismos de resposta imune, os aspectos envolvidos na defesa inata do recém-nascido não são totalmente compreendidos. O objetivo deste estudo foi descrever os mecanismos imunes inatos envolvidos na defesa dos neonatos contra a candidíase invasiva. Trata-se de uma revisão integrativa da literatura a partir das bases de dados Scopus, Scifinder, Medline, Web of Science e nas bibliotecas eletrônicas ScienceDirect e Scielo, no período de 2002 a 2020, com resgate baseado no descritor primário “Imunidade Inata” e descritores secundários “Candidíase Invasiva” e “Recém-Nascido”. Observamos o envolvimento de vários mecanismos na resposta neonatal contra a candidíase invasiva, incluindo o reconhecimento, sinalização, recrutamento e início de uma resposta imune efetiva. Esses mecanismos englobam a presença de peptídeos antimicrobianos, fagocitose, síntese de espécies reativas de oxigênio, mediadores inflamatórios e sistemas complexos de sinalização celular mediados por Receptores de Reconhecimento de Padrões (PRRs). Com este estudo, espera-se contribuir para a expansão do conhecimento sobre os mecanismos imunológicos envolvidos na resposta imune inata do recém-nascido contra infecções disseminadas causadas por espécies de Candida e, da mesma forma, destacar a importância desse conhecimento como reflexo na redução da mortalidade no período neonatal. spp crítico prematuros comuns recémnascido recém nascido compreendidos invasiva Tratase Trata se Scopus Scifinder Medline Scielo 200 2020 Imunidade Inata Candidíase Invasiva RecémNascido.

ABSTRACT A 7-week-old male delivered by cesarean section presented with a positive serology for dengue along with preretinal and retinal hemorrhages, vitreous opacities and cotton wool spots. The patient and his mother had positive serologies for Non Structural Protein 1 (NS1) by ELISA. Retinal and vitreous findings improved over a sixteen-week period. Spectral domain optical coherence tomography (OCT) showed preserved macular architecture. In this case report, we suggest that retinal and vitreous changes may be the ocular presenting features of vertically transmitted dengue in newborns, and that those findings may resolve with no major structural sequelae. 7weekold weekold 7 week old hemorrhages spots NS1 NS (NS1 ELISA sixteenweek sixteen period OCT (OCT architecture report newborns sequelae (NS

RESUMO Neonato de 7 semanas, do sexo masculino, nascido de parto cesárea, apresentou sorologia positiva para dengue com hemorragias retinianas e pré-retinianas, opacidades vítreas e manchas algodonosas. O paciente e sua mãe haviam apresentado sorologias positivas para Non Structural Protein 1 através de ELISA. Achados na retina e no vítreo melhoraram em um período de dezesseis semanas. O exame de tomografia de coerência óptica de domínio espectral demonstrou arquitetura macular preservada. Neste relato de caso, sugerimos que alterações na retina e no vítreo podem ser os achados oculares aparentes em neonatos com infecção vertical por dengue, e que estes podem se resolver sem maiores sequelas estruturais. semanas masculino cesárea préretinianas, préretinianas pré retinianas, pré-retinianas algodonosas ELISA preservada caso estruturais

ABSTRACT Objective: To evaluate the focus of pediatricians’ gaze during the heel prick of neonates. Methods: Prospective study in which pediatricians wearing eye tracker glasses evaluated neonatal pain before/after a heel prtick. Pediatricians scored the pain they perceived in the neonate in a verbal analogue numerical scale (0=no pain; 10=maximum pain). The outcomes measured were number and time of visual fixations in upper face, lower face, and hands, in two 10-second periods, before (pre) and after the puncture (post). These outcomes were compared between the periods, and according to pediatricians’ pain perception: absent/mild (score: 0–5) and moderate/intense (score: 6–10). Results: 24 pediatricians (31 years old, 92% female) evaluated 24 neonates. The median score attributed to neonatal pain during the heel prick was 7.0 (Interquartile range: 5–8). Compared to pre-, in the post-periods, more pediatricians fixed their gaze on the lower face (63 vs. 92%; p=0.036) and the number of visual fixations was greater on the lower face (2.0 vs. 5.0; p=0.018). There was no difference in the number and time of visual fixations according to the intensity of pain. Conclusions: At bedside, pediatricians change their focus of attention on the neonatal face after a painful procedure, focusing mainly on the lower part of the face.

RESUMO Objetivo: Avaliar o foco do olhar do pediatra durante a punção do calcanhar de neonatos. Métodos: Estudo prospectivo no qual pediatras, utilizando óculos de rastreamento visual, avaliaram a dor neonatal antes/depois de uma punção de calcanhar. Os pediatras pontuaram a dor de acordo com a sua percepção por meio de uma escala analógica verbal (0=sem dor; 10=dor máxima). Os desfechos analisados foram o número e o tempo das fixações visuais na face superior, face inferior e mãos, em dois períodos de 10 segundos, antes (PRÉ) e depois da punção (PÓS). Os resultados foram comparados entre os períodos e segundo a percepção da dor do pediatra: ausente/leve (escore: 0–5) e moderada/grave (escore: 6–10). Resultados: Vinte e quatro pediatras (31 anos, 92% sexo feminino) avaliaram 24 neonatos. A mediana do escore atribuído à dor do recém-nascido durante a punção do calcanhar foi 7,0 (intervalo interquartil: 5–8). Comparado ao período PRÉ, no período PÓS, o maior número de pediatras fixou o olhar na face inferior (63 vs. 92%; p=0,036) e o número de fixações visuais foi maior na face inferior (2,0 vs. 5,0; p=0,018). Não houve diferença no número e no tempo das fixações visuais de acordo com a intensidade da dor. Conclusões: À beira do leito, os pediatras mudam seu foco de atenção visual na face do recém-nascido após um procedimento doloroso, focando o olhar principalmente na parte inferior da face.

ABSTRACT Objective: To describe the newborn population with Patau (T13) and Edwards Syndrome (T18) with congenital heart diseases that stayed in the Intensive Care Unit (ICU) of a quaternary care hospital complex, regarding surgical and non-surgical medical procedures, palliative care, and outcomes. Methods: Descriptive case series conducted from January/2014 to December/2018 through analysis of records of patients with positive karyotype for T13 or T18 who stayed in the ICU of a quaternary hospital. Descriptive statistics analysis was applied. Results: 33 records of eligible patients were identified: 27 with T18 (82%), and 6 T13 (18%); 64% female and 36% male. Eight were preterm infants with gestational age between 30–36 weeks (24%), and only 4 among the 33 infants had a birth weight >2500 g (12%). Four patients underwent heart surgery and one of them died. Intrahospital mortality was 83% for T13, and 59% for T18. The majority had other malformations and underwent other surgical procedures. Palliative care was offered to 54% of the patients. The median hospitalization time for T18 and T13 was 29 days (range: 2–304) and 25 days (13–58), respectively. Conclusions: Patients with T13 and T18 have high morbidity and mortality, and long hospital and ICU stays. Multicentric studies are needed to allow the analysis of important aspects for creating protocols that, seeking therapeutic proportionality, may bring better quality of life for patients and their families.

RESUMO Objetivo: Descrever a população de recém-nascidos com síndrome de Patau (T13) e Edwards (T18) portadores de cardiopatias congênitas, que permaneceram em Unidades de Terapia Intensiva (UTI) de um complexo hospitalar quaternário, com relação a conduta cirúrgica ou não, cuidados paliativos e seus desfechos. Métodos: Série de casos de pacientes internados entre janeiro de 2014 a dezembro de 2018, com análise dos prontuários de portadores de T13 ou T18 que permaneceram internados em UTI que recebem neonatos nesse hospital quaternário. Utilizou-se análise estatística descritiva. Resultados: Foram identificados 33 prontuários para análise — 27 T18 (81,8%) e seis T13 (18,2%); 64% do sexo feminino e 36% do sexo masculino. Oito foram prematuros, nascidos com 30 a 36 semanas (24,2%), e apenas quatro nasceram com mais de 2500 g (12,1%). Quatro pacientes foram submetidos a cirurgia cardíaca e um deles foi a óbito. A mortalidade intra-hospitalar foi de 83% para T13 e 59% para T18. A maioria apresentava outras malformações e foi submetida a outras cirurgias. Cuidados paliativos foram oferecidos a 54% dos pacientes. A mediana do tempo de hospitalização para T18 e T13 foi respectivamente de 29 dias (variação: 2–304) e 25 dias (13–58). Conclusões: Pacientes com T13 e T18 cursam com alta morbimortalidade e longa permanência hospitalar em UTI. São necessários estudos multicêntricos para melhor análise de aspectos importantes para a criação de protocolos que, buscando proporcionalidade terapêutica, tragam melhor qualidade de vida para os pacientes e suas famílias.
