Presence of metabolic syndrome markers in very low birth weight ex-premature infants during early adolescence.

OBJECTIVES: To investigate the association of growth patterns with overweight/obesity and markers of metabolic syndrome in ex-premature adolescents; to assess the relationship between the increase (1 SD) in Z-score weight at term and at 2 years with outcomes in adolescents with or without intrauterine growth restriction; and to evaluate the association between the Cook criteria and overweight/obesity according to body mass index. METHODS: Cohort, retrospective, analytical study. Population: adolescents born weighting<1,500 g. RESULTS: One hundred twenty-seven adolescents (11.3 years) were included. There is an association between the 1 SD increase in the percentile (Pc) of weight at 40 weeks and at 2 years in the population with adequate birth weight (PCA) with insulin levels, resistance, and sensitivity at 11 years. Catch-up at 2 years was associated with significantly higher proportion of HDL value<41 (18.75 vs. 5.36 %) OR 4.08 95% CI (1.04-16.05) p=0.031. Overweight/obesity was associated with waist circumference index>0.5, HDL<41, and with blood pressure greater than Pc 90 for sex and height. CONCLUSIONS: In preterm infants, a 1 SD increase in weight Z score at 40 weeks and 2 years was predictive of metabolic and cardiovascular disorders in adolescence.

Maternal vaccination against COVID-19 and neonatal outcomes during Omicron: INTERCOVID-2022 study.

BACKGROUND: In early 2023, when Omicron was the variant of concern, we showed that vaccinating pregnant women decreased the risk for severe COVID-19-related complications and maternal morbidity and mortality. OBJECTIVE: This study aimed to analyze the impact of COVID-19 during pregnancy on newborns and the effects of maternal COVID-19 vaccination on neonatal outcomes when Omicron was the variant of concern. STUDY DESIGN: INTERCOVID-2022 was a large, prospective, observational study, conducted in 40 hospitals across 18 countries, from November 27, 2021 (the day after the World Health Organization declared Omicron the variant of concern) to June 30, 2022, to assess the effect of COVID-19 in pregnancy on maternal and neonatal outcomes and to assess vaccine effectiveness. Women diagnosed with laboratory-confirmed COVID-19 during pregnancy were compared with 2 nondiagnosed, unmatched women recruited concomitantly and consecutively during pregnancy or at delivery. Mother-newborn dyads were followed until hospital discharge. The primary outcomes were a neonatal positive test for COVID-19, severe neonatal morbidity index, severe perinatal morbidity and mortality index, preterm birth, neonatal death, referral to neonatal intensive care unit, and diseases during the neonatal period. Vaccine effectiveness was estimated with adjustment for maternal risk profile. RESULTS: We enrolled 4707 neonates born to 1577 (33.5%) mothers diagnosed with COVID-19 and 3130 (66.5%) nondiagnosed mothers. Among the diagnosed mothers, 642 (40.7%) were not vaccinated, 147 (9.3%) were partially vaccinated, 551 (34.9%) were completely vaccinated, and 237 (15.0%) also had a booster vaccine. Neonates of booster-vaccinated mothers had less than half (relative risk, 0.46; 95% confidence interval, 0.23-0.91) the risk of being diagnosed with COVID-19 when compared with those of unvaccinated mothers; they also had the lowest rates of preterm birth, medically indicated preterm birth, respiratory distress syndrome, and number of days in the neonatal intensive care unit. Newborns of unvaccinated mothers had double the risk for neonatal death (relative risk, 2.06; 95% confidence interval, 1.06-4.00) when compared with those of nondiagnosed mothers. Vaccination was not associated with any congenital malformations. Although all vaccines provided protection against neonatal test positivity, newborns of booster-vaccinated mothers had the highest vaccine effectiveness (64%; 95% confidence interval, 10%-86%). Vaccine effectiveness was not as high for messenger RNA vaccines only. Vaccine effectiveness against moderate or severe neonatal outcomes was much lower, namely 13% in the booster-vaccinated group (all vaccines) and 25% and 28% in the completely and booster-vaccinated groups, respectively (messenger RNA vaccines only). Vaccines were fairly effective in protecting neonates when given to pregnant women ≤100 days (14 weeks) before birth; thereafter, the risk increased and was much higher after 200 days (29 weeks). Finally, none of the neonatal practices studied, including skin-to-skin contact and direct breastfeeding, increased the risk for infecting newborns. CONCLUSION: When Omicron was the variant of concern, newborns of unvaccinated mothers had an increased risk for neonatal death. Neonates of vaccinated mothers had a decreased risk for preterm birth and adverse neonatal outcomes. Because the protective effect of COVID-19 vaccination decreases with time, to ensure that newborns are maximally protected against COVID-19, mothers should receive a vaccine or booster dose no more than 14 weeks before the expected date of delivery.

Recomendaciones para la evaluación del tamaño al nacer y del crecimiento posnatal de los recién nacidos prematuros / Recommendations for the assessment of birth size and postnatal growth of preterm newborns

Es innegable la necesidad de contar con curvas estándar de tamaño al nacer y crecimiento para evaluar y contribuir a orientar las acciones en la atención del neonato. Durante muchos años, se utilizaron las referencias de Lejarraga y Fustiñana, que fueron progresivamente reemplazadas por las de Fenton y Kim.Recientemente, el proyecto INTERGROWTH-21st construyó estándares de crecimiento prescriptivo para evaluar el tamaño al nacer desde las 33 semanas de edad gestacional, referencias para evaluar el tamaño al nacer desde las 24 a las 32,6 semanas de edad gestacional y curvas para el seguimiento longitudinal del crecimiento de recién nacidos pretérmino desde las 27 semanas de edad gestacional. Los Comités de Crecimiento y Desarrollo y de Estudios Feto-neonatales de la Sociedad Argentina de Pediatría, en conjunto con la Secretaría de Gobierno de Salud de la Nación, acordaron recomendar el reemplazo de las curvas de Fenton y Kim por las de INTERGROWTH-21st

It is unquestionable the need to have standards of size at birth and growth to evaluate and contribute to guide the actions in the care of the newborn. For many years the references of Lejarraga and Fustiñana were used, progressively replaced by those of Fenton and Kim. However, recently, the INTERGROWTH-21st project has developed prescriptive growth standards to evaluate the size at birth from 33 weeks of gestational age, references from 24 to 32.6 weeks of gestational age, and curves for postnatal growth from 27 weeks of gestational age onward. The Growth and Development and Neonatal Fetal Studies Committees of the Argentine Society of Pediatrics in conjunction with the Secretary of National Government of Health agreed to recommend the replacement of the Fenton and Kim curves with those of INTERGROWTH-21st.

Consenso: seguridad del paciente y las metas internacionales / Patient safety and the international goals: Consensus document

La seguridad del paciente es una de las dimensiones de la atención. Los avances médicos han tornado los procesos de atención cada vez más complejos, y, usualmente, hay una conjunción de circunstancias que confluyen para que ocurran errores. Los eventos adversos constituyen un problema grave de salud pública al ocasionar daños de diversos grados al paciente y a su familia, lo cual, además, lleva a incrementar el costo del proceso de atención y la estancia hospitalaria.La mayoría de los eventos adversos se producen en los hospitales, ya que, por su complejidad, su población está sometida a un mayor riesgo asociado a la atención. Se presenta este consenso con el objetivo de ofrecer herramientas cuya implementación contribuya a brindar una atención más segura.

Patient safety is one of the dimensions of care. Medical advances have made assistance processes more and more complex, and there isusually a combination of circumstances that converge for errors to occur. Adverse events constitute a serious public health problem, causing damages of varying degrees to the patient and his family, which also leads to an increase in the cost of the care process and hospital stay. Most of the adverse events occur in hospitals because their complexity is subject to a greater risk associated with care. That is why we present this consensus with the aim of offering tools whose implementation can contribute to provide a safer healthcare.

Environmental Pollution as a Risk Factor in Testicular Tumour Development: Focus on the Interaction between Bisphenol A and the Associated Immune Response.

Bisphenol A (BPA) is an endocrine disruptor to which animals and humans are highly exposed. Many reports have established a relationship between BPA exposure and breast cancer incidence, especially during critical periods of development. However, its effects on the immune response in testicular tumour growth have not yet been described. Thus, we wanted to analyse the effect of perinatal BPA exposure in pregnant female mice and the immune response modulation and tumour growth in an intratesticular cancer model in offspring male mice. Pregnant female mice were exposed to a dose of 250 mg/kg/day/body weight of BPA in their drinking water. In adulthood, male offspring underwent intrascrotal inoculation with 4T1 cancer cells. On day 21 after inoculation, mice were euthanised, and serum was obtained to measure BPA levels using HPLC coupled to mass spectrometry. The percentages of immune cell populations in peripheral lymph nodes (PLN), the spleen and tumours were evaluated by flow cytometry. In addition, the tumour expression of IL-10, TNF-α and TGF-ß was analysed by RT-PCR. Of note, we found detectable circulating levels of BPA in the offspring of mothers exposed to it while pregnant. Remarkably, BPA treatment promoted tumour growth by about 75% compared to mice coming from female mice that did not receive the compound. Perinatal exposure to BPA modulated the percentages of different immune cells in the spleen and PLN. In addition, the expression of inflammatory-related cytokines (IL-10 and TNF-α) in the tumours was significantly enhanced compared to control and vehicle groups. In conclusion, the perinatal BPA administration in pregnant female mice modulated different cellular and molecular immune components that resulted in outstanding testicular tumour size in male offspring.

Bases para el desarrollo e implementación de un modelo de información en salud de la mujer y perinatal orientado a la gestión en Latinoamérica

[RESUMEN]. Objetivo. El Sistema Informático Perinatal (SIP) ha marcado un hito en el uso de información sistematizada en la Región de las Américas. Lo que se ha aprendido ha contribuido al desarrollo de un modelo basado en un conjunto mínimo de indicadores (CMI). El objetivo del estudio fue describir el proceso histórico y metodológico de desarrollo, implementación y escalamiento territorial de un CMI para monitorizar y evaluar políticas, programas y servicios de salud de la mujer y perinatal orientado a la gestión (SIP-GESTIÓN). Métodos. El estudio se llevó a cabo en dos etapas: 1) validación en cuatro fases de un CMI en una red de hospitales: a) construcción del modelo teórico de indicadores, b) implementación de la investigación operativa, c) selección final de indicadores, y d) definición de patrones de referencia, y 2) escalamiento territorial. Resultados. Se identificaron 17 modelos de indicadores. El modelo inicial incluyó 177 indicadores agrupados en siete dimensiones (contexto, hábitos, accesibilidad, uso de servicios, calidad de cuidados, impacto materno-fetal, e impacto materno-neonatal) que se redujeron a 21 tras tres rondas Delphi. El modelo final (SIP-GESTIÓN) incluyó 40 indicadores. Se analizaron 240 021 partos (79,1%) de un total de 303 559 atendidos en las 122 maternidades seleccionadas en 24 Jurisdicciones (100%) de Argentina. La información se presenta a nivel nacional y desagregada por región sanitaria, provincia y hospital. Conclusiones. Este modelo permitió alcanzar altos niveles de cobertura y calidad de la información y escalamiento territorial y es útil para la gestión, la investigación y la reorientación de programas y políticas.

[ABSTRACT]. Objective. The Perinatal Information System (SIP) represents a milestone in the use of systematized information in the Region of the Americas. What has been learned from the system has contributed to the development of a model based on a set of core indicators (SCI). The objective of the study was to describe the historical and methodological process involved in the development, implementation, and territorial scaling-up of an SCI to monitor and evaluate women’s and perinatal health policies, programs, and services geared to management (SIP-GESTIÓN). Methods. The study was conducted in two stages: 1) a four-phase validation of an SCI in a hospital network: a) construction of the theoretical indicator model, b) operations research, c) final selection of the indicators, and d) the definition of reference standards; and 2) territorial scaling-up. Results. A total of 17 indicator models were identified. The initial model included 177 indicators divided into seven dimensions (context, habits, accessibility, use of services, quality of care, maternal and fetal impact, and maternal and neonatal impact), with 21 indicators remaining after three Delphi rounds. The final model (SIPGESTIÓN), which included 40 indicators, was then used to study 240,021 (79.1%) of the 303,559 deliveries attended in 122 selected maternity facilities in 24 jurisdictions (100%) in Argentina. The information is presented in national terms and by health region, province, and hospital. Conclusions. This model has made it possible to achieve high levels of information coverage and quality and territorial scaling-up and is useful for management, research, and the reorientation of programs and policies.

Crecimiento en prematuros con dos modalidades de fortificación de leche humana / Growth in premature infants with two modalities of human milk fortification

INTRODUCCIÓN La LH es el alimento ideal para los recién nacidos prematuros, sin embargo, pese a la fortificación estándar, estos presentan menor crecimiento que los alimentados con fórmula con altas tasas de restricción de crecimiento extrauterino, lo cual podría explicarse por la variabilidad de la composición de la LH. OBJETIVOS Principal; comparar el crecimiento de prematuros <32 semanas con 2 modalidades de fortificación de la LH. Secundario; analizar las diferencias en la composición de la LH. DISEÑO Ensayo clínico randomizado, controlado, ciego comparando 2 modalidades de fortificación de la LH; Individualizada a través del análisis de la LH por medio de espectroscopía infrarroja y ajuste a los requerimientos determinados para EG con el agregado de fortificador estándar+concentrado proteico vs Ajustada según BUN; se determinó BUN 2 veces por semana y se ajusta el contenido de proteínas mediante el agregado de fortificador estándar+concentrado proteico. Se evaluó el crecimiento mediante peso, talla, perímetro cefálico, índice talón-rodilla. RESULTADOS Hasta el momento se reclutaron 45 pacientes de los cuales 35 completaron la evaluación (de n=88). Se consideró un tiempo mínimo de permanencia de 2 semanas. Se han analizado 1338 muestras de LH de banco y 625 de LH fresca mediante MIRIS y se comparó la composición proteica. La mediana de proteínas de la LHF fue 1.5g/dL (0,6-2,5) y la LHB fue 1.2g/dL (0.38-2.4) p=<0.001. En 40% de las muestras la cantidad de proteínas fue <1,2g/dL, en 36% entre 1,2-1,6 g/dL y en 24% >1,6 g/dL, lo cual nos permitiría estimar que sólo el 24% de los pacientes alcanzaría el aporte proteico recomendado con la fortificación estándar. DISCUSIÓN No podemos definir aún si un modelo de fortificación sería más conveniente que otro. Podemos reafirmar, mediante el análisis de la LH, la necesidad de reevaluar los modelos de fortificación, dado a que la amplia variabilidad en la composición de la misma, no permite alcanzar en muchos casos aun con la fortificación estándar los requerimientos proteicos recomendados

[Recommendations for palivizumab use. Update 2015]. / Recomendaciones sobre el uso de palivizumab. Actualización 2015.

This recommendation updates the Argentinean Pediatrics' Neonatal Committee (CEFEN) ones published in 2007. The respiratory syncytial virus is the most frequent agent for lower respiratory infection. Tiny premature, bronchopulmonary dysplasia and significant hemodynamic congenital heart disease babies are the most vulnerable populations. Palivizumab is a humanized monoclonal antibody against respiratory syncytial virus used in the cold season. These recommendations are based on the scientific review of the literature published up to date. We reinforce the importance of general prevention measures like hand hygiene and family education among others. During the predominant season of respiratory syncytial virus in our country (April to September) a monthly dose of intramuscular 15 mg/kg of palivizumab is recommended. The safety and effectiveness has been proved as well as a reduction in the hospitalizations rates. In addition, epidemiological data of previous years are provided here.

Esta recomendación actualiza la publicada en el año 2007 por el Comité de Estudios Fetoneonatales (CEFEN). El virus respiratorio sincicial es el agente etiológico más frecuente de infección respiratoria aguda baja. La población más vulnerable es la de los prematuros pequeños, los lactantes con displasia broncopulmonar y cardiopatías congénitas hemodinámicamente significativas. El palivizumab es un anticuerpo monoclonal humanizado contra el virus respiratorio sincicial, que se aplica durante la estación invernal. Estas recomendaciones surgen de la revisión crítica de la literatura publicada hasta la fecha. Destacamos la importancia de promover las medidas generales de prevención de infecciones, como la higiene de manos y la educación a la familia, entre otras. Durante la estación predominante de virus respiratorio sincicial en nuestro país (de abril a septiembre), se recomienda indicar, en la población de riesgo, una dosis mensual de 15 mg/kg de palivizumab por vía intramuscular. Esto ha demostrado ser seguro y efectivo y ha producido una reducción en las tasas de internación. Se adicionan datos epidemiológicos de nuestro país de años anteriores.

Sex steroids effects on the molting process of the helminth human parasite Trichinella spiralis.

We evaluated the in vitro effects of estradiol, progesterone, and testosterone on the molting process, which is the initial and crucial step in the development of the muscular larvae (ML or L1) to adult worm. Testosterone had no significative effect on the molting rate of the parasite, however, progesterone decreased the molting rate about a 50% in a concentration- and time-independent pattern, while estradiol had a slight effect (10%). The gene expression of caveolin-1, a specific gene used as a marker of parasite development, showed that progesterone and estradiol downregulated its expression, while protein expression was unaffected. By using flow citometry, a possible protein that is recognized by a commercial antiprogesterone receptor antibody was detected. These findings may have strong implications in the host-parasite coevolution, in the sex-associated susceptibility to this infection and could point out to possibilities to use antihormones to inhibit parasite development.

Participación de las madres en el cuidado de los recién nacidos internados en un servicio de neonatología que aplica el modelo de maternidad centrada en la familia / Participation of mothers in the care of newborns admitted to a neonatal model applying family-centered maternity

La participación activa de las madres en las unidades de terapia intensiva neonatales es beneficiosa para sus recién nacidos, mejora su crecimiento, disminuye el riesgo de infecciones y se asocia con mayor producción de leche humana. El objetivo de este estudio fue cuantificar las actividades que desarrollan las madres dentro de la unidad y estimar la reducción del tiempo de enfermería atribuible a su presencia. Diseño: Transversal, descriptivo. Resultados: Durante una semana las madres realizaron 798 prácticas a las que se les podrían atribuir 75 horas y 23 minutos (percentilos 10-90: 16 -123 hs) de trabajo de enfermería. Conclusión: Este estudio permitió conocer y cuantificar las principales actividades asociadas al cuidado de las madres de los niños internados y se logró una reducción en la carga de trabajo de enfermería equivalente a más de 12 turnos de enfermería de 6 hs en una semana.

The objective of this study was to quantify the activities that mothers do within the unit in the care of their babies and to estimate the reduction of nursing time attributable to their presence. Design: Descriptive, cross section. Results: During a week, mothers conducted 798 practices with an estimate of 75 hours and 23 minutes (Percentiles 10-90: 16 -123 hours) of nursing work. Conclusion: This study allowed us to know and quantify the main activities that mothers perform in the care of their own babies staying in the NICU, This activities represent a reduction in nursing workload equivalent to more than 12 nursing shifts of 6 hours in a week.

[Laser treatment for retinopathy of prematurity in 27 public services of Argentina]. / Tratamiento con láser por retinopatía del prematuro en 27 servicios públicos argentinos.

INTRODUCTION: Retinopathy of prematurity may lead to partial loss of vision and blindness; laser photocoagulation is the elective treatment, but universal access to it is not yet guaranteed in Argentina. OBJECTIVES: To estimate prevalence of children requiring laser for retinopathy, their clinical and demographic characteristics, place of origin and place of treatment. POPULATION, MATERIAL AND METHOD: Observational, descriptive and retrospective study. POPULATION: premature newborns who required treatment at public services during 2008. VARIABLES: Birth weight and gestational age, prognosis, unusual cases and missed opportunities. SOURCE: 27 public services from 18/24 provinces. RESULTS: 235 patients who required treatment were recorded (Garrahan Hospital: 86; Gutiérrez Hospital: 45, and 104 from 25 other hospitals) from 77 public services and 13 private services from 22/24 provinces, where 210,720 babies born at the same period. Cases from Buenos Aires Province were referred mainly to Garrahan Hospital, all cases from Buenos Aires City and 2/3 from the rest of the country were treated in situ. Prognosis was defined as reserved at 15% and 5 missed opportunities occurred all in referred babies. Unusual cases were 27% of the total reported. CONCLUSION: In this population retinopathy prevalence was 1/900 birth in 2008. The proportion of unusual cases, reserved prognosis and missed opportunities was high. A national record and improved access to treatment in situ are urgently needed.
