Objective: Phenobarbital increases electroclinical uncoupling and our preliminary observations suggest it may also affect electrographic seizure morphology. This may alter the performance of a novel seizure detection algorithm (SDA) developed by our group. The objectives of this study were to compare the morphology of seizures before and after phenobarbital administration in neonates and to determine the effect of any changes on automated seizure detection rates. Methods: The EEGs of 18 term neonates with seizures both pre- and post-phenobarbital (524 seizures) administration were studied. Ten features of seizures were manually quantified and summary measures for each neonate were statistically compared between pre- and post-phenobarbital seizures. SDA seizure detection rates were also compared. Results: Post-phenobarbital seizures showed significantly lower amplitude (p < 0.001) and involved fewer EEG channels at the peak of seizure (p < 0.05). No other features or SDA detection rates showed a statistical difference. Conclusion: These findings show that phenobarbital reduces both the amplitude and propagation of seizures which may help to explain electroclinical uncoupling of seizures. The seizure detection rate of the algorithm was unaffected by these changes. Significance: The results suggest that users should not need to adjust the SDA sensitivity threshold after phenobarbital administration.

Metodología: el diseño metodológico utilizado fue de casos y controles con pareamiento doble (edad y sexo) e incluyó a niños/as menores de seis meses que fueron atendidos en consulta externa de la Fundación Pablo Jaramillo de Cuenca entre julio y octubre de 2007. El universo fue infinito y homogéneo, con muestra probabilística (74 casos y 148 controles). El desarrollo psicomotor se valoró con el test de Brunet-Lézine. El análisis estadístico se basó en Odds ratios crudos y Odds ratios ajustados. Resultados: los factores con asociación significativa al retraso del desarrollo psicomotor fueron, en el análisis bivariado, la prematuridad (OR 2.5, IC 951.2-5.1, p 0.009), peso al nacimiento menor a 2500 g (OR 10.6, IC 954.3-26.0, p 0.000), desnutrición posnatal (OR 12.1, IC 954.4-33.6, p 0.000), perímetro cefálico pequeño para la edad posnatal (OR 3.2, IC 951.4-7.7, p 0.006), talla baja para la edad posnatal (OR 4.2, IC 951.9-9.2, p 0.000) y condición neurológica anormal (OR 11.3, IC 955.8-21.8, p 0.000). En la regresión logística, la prematuridad (OR 2.6, IC 951.2-5.8, p 0.015) ajustada por los factores perinatales, la desnutrición posnatal (OR 35.4, IC951.2-1024.1, p 0.038) y la anormalidad en la condición neurológica (OR 8.5, 4.0-18.2, p 0.000) ajustadas por los factores perinatales y posnatales. Conclusiones: los factores de riesgo significativos asociados al retraso del desarrollo psicomotor fueron la prematuridad ajustada por factores perinatales, la desnutrición posnatal y la anormalidad en la condición neurológica ajustadas por los factores perinatales y posnatales

Estudio descriptivo en la unidad de Neonatología del Hospital Vicente Corral Moscoso de la ciudad de Cuenca en el período comprendido entre enero y junio de 1999 con el fin de determinar la frecuencia y etiología de SDepsis en los recién nacidos con riesgo. De los 40 recién nacidos con riesgo de sepsis, a quiénes se les realizaron hemocultivos, se observó que el 30fueron positivos. Los prematuros que representan el 65, son los principales pacientes con hemocultivos positivos. El 75de recien nacidos presentaron sepsis temprana, es decir tenían menos de 7 días de vida. La prematurez fue el principal factor de riesgo para desarrollar sepsis con el 50, seguido del embarazo gemelar y procedimientos inasivos con el 25cada uno. Los exámenes de laboratorio como el hemograma, plaquetas, no son del todo concluyentes para diagnosticar sepsis. Las manifestaciones clínicas más frecuentes de los recién nacidos que presentaron sepsis fueron en orden de importancia los siguientes: neurológicas, respiratorias, digestivas y dermatológicas. El Enterobacter fue la bacteria más frecuente causante de sepsis con el 50, seguido por esteptococo 16.7, Klebsiella y E. Coli con el 8.3cada uno. El 33.3de recién nacidos con sepsis fallecieron

Aim This paper will report findings from the first phase of an evaluation of a new e-health intervention designed to allow mothers to ‘see’ their baby in neonatal care (NNU) when they are not able to be with them. The intervention, MyLittleOne, involves a web-camera being placed over the incubator in NNU, which transmits a real-time video wirelessly to a coupled tablet device at the mother’s bedside. Guided by the MRC Framework for the Development and Evaluation of Healthcare Interventions (MRC, 2008), the aim was to explore parent and professional views of the technology and make recommendations for its future development, use and evaluation. Methods A qualitative approach was adopted, guided by a critical realist perspective (McEvoy and Richards, 2003). The study took place in a Level 3 NNU in Scotland. Participants were recruited purposively and included parents (n = 33) and a range of health professionals working in neonatal and postnatal care (n = 21). The data were collected during semi-structured individual, paired and small group interviews and were analysed thematically using NVivo v10. Results The majority of parents and professionals spoke positively about MyLittleOne. Perceptions were that: use of the technology assisted bonding and responsiveness; it promoted the recovery process following birth; and, for mothers who wished to breast-feed, being able to see their baby on the tablet device encouraged the ‘let-down’ reflex. An additional benefit was that siblings and others who may not be able to visit the NNU were able to see the baby. In contrast, for a small number of mothers, viewing their baby remotely appeared to increase their levels of anxiety. Switching off the camera during a medical procedure and back on after the procedure was completed was found to be problematic, at times and in different ways, for both parents and professionals. Conclusions Findings from this preliminary evaluation will guide future developments of the technology, including its use in family homes following the mother’s discharge. The findings will also inform the design of a feasibility study and subsequent RCT to assess the impact of MyLittleOne on a range of psychological indicators of postnatal adjustment.

Background: Anthropometric indicators are difficult to interpret in very low birth weight (VLBW) premature infants, including both appropriate for gestational age (AGA) and small for gestational age (SGA) infants. Therefore, the purpose was to describe the anthropometric indicators of growth and nutritional status in VLBW premature infants AGA and SGA, hospitalized in a neonatal intensive care unit (NICU). Study design: The descriptive and prospective study design included 114 preterm infants, adequate for gestational age/small for gestational age hospitalized in the intensive care unit. Head, thigh, mid upper arm circumference, skin-fold measurements and weight/age, length/ age, and weight/length indices were obtained. Correlations were made among the anthropometric indices, and a multivariate regression analysis with weight/age as dependent variable was performed. Results: Weight/age in AGA premature infants had high number of significant anthropometric correlations. The SGA premature infants had few and weak correlations. The regression analysis showed that anthropometric indices better explain changes in the weight/age index in adequate for gestational age premature infants. Conclusion: Weight/age in the VLBW/AGA premature infants could reflect growth, nutritional status and energy stored as fat, but in the VLBW/SGA premature infants, thigh circumference and mid arm circumference would be better indicators just of nutritional status.

Laparoscopic surgery is associated with reduced surgical trauma, and less acute phase response, as compared with open surgery. Cytokines are important regulators of the biological response to surgical and anesthetic stress. The aim of this study was to determine if CO2 pneumoperitoneum would change cytokine expression, gas parameters and leukocyte count in septic rats. Methods: Wistar rats were randomly assigned to five groups: control (anesthesia only), laparotomy, CO2 pneumoperitoneum, cecum ligation and puncture by laparotomy, and laparoscopic cecum ligation and puncture. After 30 min of the procedures, arterial blood samples were obtained to determine leukocytes subpopulations by hemocytometer. TNFα, IL-1β, IL-6 were determined in intraperitoneal fluid (by ELISA). Gas parameters were measured on arterial blood, intraperitoneal and subperitoneal exsudates. Results: Peritoneal TNFα, IL-1β and IL-6 concentrations were lower in pneumoperitoneum rats than in all other groups (p<0.05). TNFα, IL-1β and IL-6 expression was lower in the laparoscopic than in laparotomic sepsis (p<0.05). Rats from laparoscopic cecum ligation and puncture group developed significant hypercarbic acidosis in blood and subperitoneal fluid when compared to open procedure group. Total white blood cells and lymphocytes were significantly lower in laparoscopic cecum ligation and puncture rats than in the laparotomic (p<0.01). Nevertheless, the laparotomic cecum ligation rats had a significant increase in blood neutrophils and eosinophils when compared with controls (p<0.05). Conclusions: This study demonstrates that the CO2 pneumoperitoneum reduced the inflammatory response in an animal model of peritonitis with respect to intraperitoneal cytokines, white blood cell count and clinical correlates of sepsis. The pneumoperitoneum produced hypercarbic acidosis in septic animals

Statins are widely recognized as hypolipemic drugs, but some studies have observed anti-inflammatory and immunomodulatory effects, known as pleiotropic. The aims of this work was to study possible anti-inflammatory effects of simvastatin in abdominal sepsis. Serum pro-inflammatory cytokines and leukocytes count were determined in an experimental model of abdominal sepsis, using cecal ligation and puncture (CLP) in rats. Methods: Twenty eigth Wistar rats weighing 285±12g were randomly divided in: CLP/Sinvastatin rats (n=7), treated with 10 mg/Kg of oral simvastatin 18 and 2 hs berofe CLP; CLP/Saline group rats (n=7), treated with oral saline; group Sham/Simvastatin (n=7), treated with simvastatin, and group Sham/Saline (n=7), treated with saline. Serum TNF-α, IL-1β and IL-6 by ELISA and total leukocytes, neutrophils, lymphocytes, and eosinophils were determined 24 hs after CLP. ANOVA and Tukey test were used considering significant p<0.05. Results: It was demonstrated that serum TNF-α, IL-1β and IL-6 were respectively 364,8±42pg/mL; 46,3±18pg/mL and 28,4±13pg/mL in CLP/Sinvastatin rats, significantly lower (p<0.05) than in group CLP/Saline (778,5±86pg/ml; 176,9±46pg/ ml; 133,6±21 pg/ml, respectively). The same results were observed in total leukocytes and neutrophils counts. Conclusion: These results clearly demonstrate that simvastatin is an effective agent that reduces cytokines levels and leukocyte count in sepsis, independently of its well-known lipid-lowering effects. Thus, HMG-CoA reductase inhibitors like simvastatin have important anti-inflammatory effects in abdominal sepsis in rats

Objective: To investigate the maternal perception of the experience in the first phase of the Kangaroo Mother Care Method in the Neonatal Intensive Care Unit (NICU). Methods: Descriptive, exploratory and qualitative study, conducted in the period from August to October 2014, with 10 mothers of newborn preterm (NP) infants, who were admitted to the Maternity School Assis Chateaubriand (MEAC) in Fortaleza, Brazil, and had received skin-to-skin contact through the Kangaroo Care Method during hospitalization in the NICU. Data was collected by semi-structured interview, directed by guiding questions. Content analysis was used for processing the data, being established four categories: “The bond and the attachment”, “Maternal competence”, “The fear of losing the baby” and “The importance of the multidisciplinary team”. Results: The Kangaroo Care Method is a safe and pleasurable practice for mothers and relatives, in addition to providing social and psychoaffective benefits, found in the imagery of the method institutionalization and in the mothers’ experience when properly supported. The meanings of the maternal feelings of apprehension as a result of the first physical contact with the hospitalized child can be evidenced. Regarding the evaluation of its clinical practice, this method has provided better development of the newborn infant and a reduction in hospital stay. Conclusion: The study shows relevance, since the evidence of the maternal perception of this method supports its establishment as a mandatory practice in maternity hospitals, in view of the benefits to the mother and the neonate.

En la cirugía neuroquirúrgica los datos sobre profilaxis antibiótica no son claros ya que no cuentan a su favor con estudios que avalen o rechacen su uso. Es por esto mismo que surge la necesidad de indagar en la prevalencia de infecciones del sitio quirúrgico y la profilaxis antibiótica preoperatoria en procedimientos neuroquirúrgicos espinales en pacientes entre la edad neonatal y los 5 años de edad. Materiales y métodos: se realizó un estudio descriptivo retrospectivo de corte transversal, haciendo revisión sistemática de los expedientes clínicos de los pacientes que ingresaron en el año 2014 que cumplieron con los criterios de inclusión. Resultados: Se estudió una población muestral correspondiente a 76 pacientes, en los que se evidencia que la mayoría de cirugías practicadas durante el periodo estudiado fue de manera electiva; sin embargo una cantidad significativa de cirugías (38%) fue sometida de emergencia, lo que predispone a infecciones y alargamiento del esquema antibiótico. El 89% de los esquemas de antibióticos fueron utilizados como tratamiento terapéutico relacionado principalmente con mielo-meningoceles y únicamente el 11% de todos los pacientes estudiados recibió profilaxis antibiótica preoperatoria pura. El 83% de los casos no se relacionó con infección de sitio quirúrgico y un 17% si lo presentó. El 86% de los casos estuvo relacionado con el uso de dos antimicrobianos de forma terapéutica y un 14% se relacionó con el uso de un solo antimicrobiano como profilaxis. Evidenciándose así, que no hay un esquema terapéutico especifico definido; y paradójicamente se evidencia una mayor prevalencia de infecciones de sitio quirúrgico con biterapia; puesto a que el 85% de los casos que desarrollaron infección de sitio quirúrgico tenían esquema de biterapia antimicrobiana y un 15% tenía esquema de monoterapia antimicrobiana. Conclusiones: La mayoría de los pacientes estudiados fueron intervenidos de manera electiva (62%); sin embargo, el 38% fue sometido a cirugía de emergencias; lo que conlleva al uso de un esquema terapéutico de tratamiento antibiótico en lugar de uno profiláctico.

Background: Post-discharge mortality is a frequent but poorly recognized contributor to child mortality in resource limited countries. The identification of children at high risk for post-discharge mortality is a critically important first step in addressing this problem. Objectives: The objective of this project was to determine the variables most likely to be associated with post-discharge mortality which are to be included in a prediction modelling study. Methods: A two-round modified Delphi process was completed for the review of a priori selected variables and selection of new variables. Variables were evaluated on relevance according to (1) prediction (2) availability (3) cost and (4) time required for measurement. Participants included experts in a variety of relevant fields. Results: During the first round of the modified Delphi process, 23 experts evaluated 17 variables. Forty further variables were suggested and were reviewed during the second round by 12 experts. During the second round 16 additional variables were evaluated. Thirty unique variables were compiled for use in the prediction modelling study. Conclusion: A systematic approach was utilized to generate an optimal list of candidate predictor variables for the incorporation into a study on prediction of pediatric post-discharge mortality in a resource poor setting.
