RESUMO

Introducción: La conciliación de la medicación (CM) es una de las principales estrategias para disminuir los errores de medicación en las transiciones asistenciales. En España existen publicadas diferentes guías con recomendaciones para la implantación y el desarrollo de la CM orientadas a la población adulta, sin estar los pacientes pediátricos incluidos. En el año 2018 se llevó a cabo un estudio que permitió la posterior publicación de un documento con criterios de selección de pacientes pediátricos en los que priorizar la CM. Objetivos: Describir las características de los pacientes pediátricos con mayor probabilidad de sufrir errores de conciliación (EC), para confirmar si los resultados de un estudio previo son extrapolables. Metodología: Estudio prospectivo y multicéntrico con pacientes pediátricos ingresados. Se analizaron los EC detectados durante la realización de la CM al ingreso. La mejor historia farmacoterapéutica posible del paciente fue obtenida utilizando diferentes fuentes de información y confirmándose con una entrevista con el paciente/cuidador. Resultados: Se detectaron 1.043 discrepancias, determinándose como EC 544, afectando a 317 pacientes (43%). La omisión de algún medicamento fue el error más común (51%). La mayoría de los EC se asociaron con los medicamentos de los grupos A (31%), N (23%) y R (11%) de la clasificación ATC. La polimedicación y la enfermedad de base onco-hematológica fueron los factores de riesgo asociados a la presencia de EC con significación estadística. Conclusiones: Los hallazgos de este estudio permiten priorizar la CM en un grupo concreto de pacientes pediátricos, favoreciendo la eficiencia del proceso. Los pacientes onco-hematológicos y la polimedicación se confirman como los principales factores de riesgo para la aparición de EC en la población pediátrica.(AU)


Introduction: Medication reconciliation (MR) is one of the main strategies used to reduce medication errors in care transitions. In Spain, several guidelines have been published with recommendations for the implementation and development of MR processes aimed at the adult population, and not applicable to paediatric patients. In 2018, a study was carried out that allowed the subsequent publication of a document establishing criteria for the selection of paediatric patients in whom CM should be prioritised. Objectives: To describe the characteristics of the paediatric patients most likely to be subject to reconciliation errors (REs) to confirm whether the results of a previous study could be extrapolated. Methodology: Prospective, multicentre study in paediatric inpatients. We analysed the REs detected in the MR at the time of admission. We obtained the best possible medication history of the patient using different sources of information, subsequently confirmed through an interview with the patient/caregiver. Results: 1043 discrepancies were detected, of which 544 were categorised as REs, affecting 317 patients (43%). Omission of a drug was the most common error (51%). Most REs involved drugs in groups A (31%), N (23%) and R (11%) of the ATC classification. Polypharmacy and oncological/haematological disease were the risk factors that exhibited a statistically significant association with the occurrence of REs. Conclusions: The findings of this study allow the prioritisation of MR in a specific group of paediatric patients, contributing to improve the efficiency of the process. Oncological/haematological disease and polypharmacy were confirmed as the main risk factors for the occurrence of REs in the paediatric population.(AU)

RESUMO

INTRODUCTION: Medication reconciliation (MC) is one of the main strategies to reduce medication errors in care transitions. In Spain, several guidelines have been published with recommendations for the implementation and development of MC aimed at the adult population, although paediatric patients are not included. In 2018, a study was carried out that led to the subsequent publication of a document with criteria for selecting paediatric patients in whom CM should be prioritised. OBJECTIVES: To describe the characteristics of paediatric patients most likely to suffer from errors of reconciliation (EC), to confirm whether the results of a previous study can be extrapolated. METHODOLOGY: Prospective, multicentre study of paediatric inpatients. We analysed the CE detected during the performance of the CM on admission. The best possible pharmacotherapeutic history of the patient was obtained using different sources of information and confirmed by an interview with the patient/caregiver. RESULTS: 1043 discrepancies were detected, 544 were identified as CD, affecting 317 patients (43%). Omission of a drug was the most common error (51%). The majority of CD were associated with drugs in groups A (31%), N (23%) and R (11%) of the ATC classification. Polymedication and onco-haematological based disease were the risk factors associated with the presence of CD with statistical significance. CONCLUSIONS: The findings of this study allow prioritisation of CM in a specific group of paediatric patients, favouring the efficiency of the process. Onco-haematological patients and polymedication are confirmed as the main risk factors for the appearance of CD in the paediatric population.

RESUMO

BACKGROUND: Currently, there is no validated method for estimating antimicrobial consumption in the neonatal population, as it exists for adults using Defined Daily Doses (DDD). In neonatology, although there are different methods, each one with advantages and disadvantages, there is no unified criterion for use. The aim of this study is to validate the neonatal DDD designed as a new standardised form of antimicrobial consumption over this population. METHODS: The validation of the neonatal DDD, Phase II of the research project, was carried out through a descriptive observational study. Periodic cut-offs were performed to collect antimicrobial prescriptions of neonates admitted to the neonatology and intensive care units of nine Spanish hospitals. The data collected included demographic variables (gestational age, postnatal age, weight and sex), antimicrobial dose, frequency and route of administration. The selection of the optimal DDD value takes into account power value, magnitude obtained from the differences in the DDD, statistical significance obtained by the Wilcoxon test and degree of agreement in the stipulated doses. RESULTS: Set of 904 prescriptions were collected and finally 860 were analysed based on the established criteria. The antimicrobials were mostly prescribed in the intensive care unit (63.1%). 32 different antimicrobials were collected, and intravenous administration was the most commonly used route. Neonatal DDD were defined for 11 different antimicrobials. A potency > 80% was obtained in 7 antibiotics. The 57.1% of the selected DDD correspond to phase I and 21.4% from phase II. CONCLUSION: DDD validation has been achieved for the majority of intravenously administered antimicrobials used in clinical practice in the neonatal population. This will make it possible to have an indicator that will be used globally to estimate the consumption of antimicrobials in this population, thus confirming its usefulness and applicability.

RESUMO

The purpose of this paper is to verify whether the concentrations of caffeine in saliva are comparable to serum concentrations in preterm infants who are treated with caffeine for apnea of prematurity. This is a prospective observational study. Eligible participants were newborn infants < 37 weeks of gestational age treated with oral or intravenous caffeine for apnea of prematurity. Two paired samples of saliva and blood were collected per patient. Tube solid-phase microextraction coupled online to capillary liquid chromatography with diode array detection was used for analysis. A total of 47 infants with a median gestational age of 28 [26-30] weeks and a mean of 1.11 ± 0.4 kg of birth weight. Median postmenstrual age, when samples were collected, was 31 [29-33] weeks. Serum caffeine median levels of 19.30 µg/mL [1.9-53.90] and salivary caffeine median levels of 16.36 µg/mL [2.20-56.90] were obtained. There was a strong positive Pearson's correlation between the two variables r = 0.83 (p < 0.001). CONCLUSION: The measurement of salivary caffeine concentrations after intravenous or oral administration offers an alternative to serum caffeine monitoring in apnea of prematurity. Measurement of salivary concentration minimizes blood draws, improves blood conservation, and subsequently minimizes painful procedures in premature infants. WHAT IS KNOWN: • Salivary sampling may be useful when is applied to extremely low birth weight infant, in whom blood sampling must be severely restricted. WHAT IS NEW: • The measurement of caffeine salivary concentrations after intravenous or oral administration offers an alternative to serum caffeine monitoring in apnoea of prematurity. • Salivary sampling may be a valid non-invasive alternative that could be used to individualize and optimize caffeine dose.

RESUMO

BACKGROUND: Staphylococcus aureus is a frequent cause of hospital-acquired bacteremia in pediatric patients. Vancomycin is the drug of choice for the treatment of methicillin-resistant strains, although treatment failure is frequently observed. Area under the curve (AUC) of plasma concentrations over the minimum inhibitory concentration (MIC) has been proposed as the best index to predict treatment response, although information about its clinical impact on pediatric patients is scarce. The objective of this study is to determine if early recovery of an AUC/MIC>400 mg*h/L for vancomycin in pediatric patients with S. aureus bacteremia is associated with clinical and microbiological treatment response. METHODS: Retrospective observational study. Pediatric patients younger than 3 years with vancomycin-treated S. aureus bacteremia were included. The pharmacokinetic parameters were calculated from the vancomycin value obtained in the first 72 hours of treatment, assuming a bicompartmental model. A multivariate analysis was performed to analyze factors associated with early clinical response, treatment failure, microbiological response and 30-day mortality. RESULTS: Fifty-one patients with S. aureus bacteremia were included in the study. In 18 patients (35.3%), strains with a MIC higher than 1.0 mg/L were isolated, being in eight (15.7%) greater than 1.5 mg/L. 22 (43.1%) patients did not reach an estimated AUC/MIC>400 during the first 72 hours. A significant association was observed between attainment of an AUC/MIC>400 and early clinical response (OR:3.23 [95% CI: 1.07-12.03]). No significant association was found between an AUC/MIC>400 and microbiological response or mortality. CONCLUSIONS: An AUC/MIC>400 is associated with early response to vancomycin in pediatric patients with S. aureus bacteremia.

RESUMO

Background: Currently, the first line treatment of persistent ductus arteriosus (PDA) is either indomethacin or ibuprofen. However, the potentially life-threatening side effects associated to their use have prompted physicians to look for alternative options. The incorporation of paracetamol as an alternative to ibuprofen in the management of PDA is still based on insufficient clinical evidence. Hence, more clinical trials are needed to establish a therapeutic role for paracetamol in the management of PDA that take into consideration short- and long-term safety and efficacy outcomes. Study Design: This is a non-inferiority, randomized, multicenter, double-blinded study to evaluate the efficacy, and safety of intravenous (IV) paracetamol vs. IV ibuprofen (standard treatment) for PDA in preterm patients with a gestational age ≤ 30 weeks. At baseline, patients will be randomized (1:1) to treatment with paracetamol or ibuprofen. The primary endpoint is closure of the ductus after the first treatment course. Secondary endpoints are related to effectiveness (need for a second treatment course, rescue treatment, reopening rate, time to definitive closure, need for surgical ligation), safety (early and long-term complications), pharmacokinetics, and pharmacodynamics, pharmacogenetics, pharmacoeconomics, and genotoxicity. Long-term follow-up to 24 months of corrected postnatal age will be performed using Bayley III neurodevelopmental scale. Trial Registration: ClinicalTrials.gov Identifier: NCT04037514.

RESUMO

Objectives To present a case report of succesfully metyrapone treatment of a neonatal patient with McCune-Albrigth syndrome (MAS), a rare disease caused by a genetically mosaic disorder and is characterized by variable hyperfunctional endocrinopathies, bone dysplasia, and café-au-lait spots. Case presentation A preterm newborn was admitted to hospital and she presented difficulty controlling hypertension, café-au-lait spots, and failure to thrive. An abdominal ultrasound and a magnetic resonance showed a high volume of both suprarenal glands. Therefore, MAS was suspected. Laboratory data confirmed adrenocorticotropic hormone-independent Cushing's syndrome with hepatic dysfunction and metyrapone treatment was initiated. A progressive normalization of cortisol levels was achieved despite poor oral tolerance. Conclusion Our case shows that metyrapone is useful in the management of neonatal Cushing's syndrome due to McCune-Albright syndrome.

RESUMO

INTRODUCTION AND OBJECTIVES: The fortification of maternal milk (MM) is a standard practice in order to achieve the requirements needed for the growth and development of the premature newborn. However, its osmolality could increase. According to the American Paediatrics Academy, it is recommended not to exceed 450 mOsm/kg (approximately 400 mOsm/L) in the diet of the infant, even though the safety limit is estimated to be between 400 and 600 mOsm/kg. The aim of this study is to determine the osmolality of thawed and fortified donated MM (DMM). METHOD: An analysis was performed on DMM of 6 healthy mothers, without fortifying, and with 4 levels of fortification. Measurement of the samples was carried out in triplicate at 0, 4, 9, and 24hours after their preparation. They were stored refrigerated (2-8°C) between measurements. The study groups were: (A) Non-fortified DMM; (B) DMM with vitamins added; (C) with the addition of a fortifier; (D) with the addition of a low-dose protein formula; and (E) with the addition of a high-dose protein formula. The osmolality determinations were carried out using a freezing-point osmometer. The data analysis was performed using R software (v.3.5.1). RESULTS: A total of 30 samples were analysed with 360 measurements. The osmolality of the DMM at t=0h was 301 mOsm/kg (SD 5.2) and slightly increased with time to 308.11 mOsm/kg (SD 5.21) after 24hours (t=24h), being maintained within the safety limits. The addition of vitamins (Group B) did not significantly increase the osmolality. The addition of a fortifier (C) and a low dose (D) or high dose (E) protein formula produced an increase in the baseline osmolality that increased statistically significantly in time (P=.007), but with no differences between the C, D, and E types. There were differences between the osmolality at t=0 with the fortification according to the manufacturer's data sheet (339 mOsm/l) and the findings in our laboratory (432.33 mOsm/l). CONCLUSION: The osmolality values found in the thawed DMM samples were similar to those of other studies. The fortification of the DMM samples and their storage refrigerated at 2-8°C for 24h increased the osmolality, but keeping them within the safety limits.

RESUMO

Fetal to neonatal transition entails cardiorespiratory, hemodynamic, and metabolic changes coinciding with the switch from placental to airborne respiration with partial pressures of oxygen of 4-5 kPa in utero raising to 8-9 kPa ex utero in few minutes. Preterm infants have immature lung and antioxidant defense system. Very preterm infants (<32 weeks' gestation) frequently require positive pressure ventilation and oxygen to establish lung aeration, a functional residual capacity, and overcome a tendency toward hypoxemia and bradycardia in the first minutes after birth. Recent studies have shown that prolonged bradycardia (heart rate <100 beats per minute) and/or hypoxemia (oxygen saturation <80%) are associated with increased mortality and/or intracranial hemorrhage. However, despite the accumulated evidence, the way in which oxygen should be supplemented in the first minutes after birth still has not yet been clearly established. The initial inspired fraction of oxygen and its adjustment within a safe arterial oxygen saturation range measured by pulse oximetry that avoids hyper-or-hypoxia is still a matter of debate. Herewith, we present a current summary aiming to assist the practical neonatologist who has to aerate the lung and establish an efficacious respiration in very preterm infants in the delivery room.

RESUMO

AIM: The adequate dosing of topiramate in neonates undergoing therapeutic hypothermia has not been established. The aim of this study was to design a dosing schedule capable of providing topiramate serum concentrations within the accepted therapeutic range. METHODS: Neonates (n = 52) with hypoxic ischaemic encephalopathy and subjected to therapeutic hypothermia were dosed with topiramate, 5 mg/kg on day one and 3 mg/kg on days two to five, to decrease seizure events. A total of 451 topiramate serum concentrations obtained in the patients were used to develop a population pharmacokinetic model using a non-linear mixed-effects modelling approach. RESULTS: A one-compartment model with first-order absorption and two different clearance terms, one for the cooling period and another for the post-warming period, were used to describe the concentration-time topiramate data. The probability of no-seizure events could not be related to topiramate concentrations, which was attributed to excessively low topiramate concentrations. A modified dosage schedule was designed with the aim of obtaining more than 90% of patients with topiramate concentrations within the therapeutic range after the first dose. CONCLUSION: The dosage schedule of topiramate in these patients should be modified with the aim of decreasing the frequency of seizure events.

RESUMO

BACKGROUND: Own mother's milk (OMM) is the optimal nutrition for preterm infants. However, pasteurized donor human milk (DHM) is a valid alternative. We explored the differences of the transcriptome in exfoliated epithelial intestinal cells (EEIC) of preterm infants receiving full feed with OMM or DHM. METHODS: The prospective observational study included preterm infants ≤ 32 weeks' gestation and/or ≤1500 g birthweight. Total RNA from EEIC were processed for genome-wide expression analysis. RESULTS: Principal component analysis and unsupervised hierarchical clustering analysis revealed two clustered groups corresponding to the OMM and DHM groups that showed differences in the gene expression profile in 1629 transcripts. The OMM group overexpressed lactalbumin alpha gene (LALBA), Cytochrome C oxidase subunit I gene (COX1) and caseins kappa gene (CSN3), beta gene (CSN2) and alpha gene (CSN1S1) and underexpressed Neutrophil Cytosolic Factor 1 gene (NCF1) compared to the DHM group. CONCLUSIONS: The transcriptomic analysis of EEIC showed that OMM induced a differential expression of specific genes that may contribute to a more efficient response to a pro-oxidant challenge early in the postnatal period when preterm infants are at a higher risk of oxidative stress. The use of OMM should be strongly promoted in preterm infants.

RESUMO

BACKGROUND AND OBJECTIVES: Therapeutic interventions to improve the efficacy of whole-body cooling for hypoxic-ischemic encephalopathy (HIE) are desirable. Topiramate has been effective in reducing brain damage in experimental studies. However, in the clinical setting information is limited to a small number of feasibility trials. We launched a randomized controlled double-blinded topiramate/placebo multicenter trial with the primary objective being to reduce the antiepileptic activity in cooled neonates with HIE and assess if brain damage would be reduced as a consequence. STUDY DESIGN: Neonates were randomly assigned to topiramate or placebo at the initiation of hypothermia. Topiramate was administered via a nasogastric tube. Brain electric activity was continuously monitored. Topiramate pharmacokinetics, energy-related and Krebs' cycle intermediates, and lipid peroxidation biomarkers were determined using liquid chromatography-mass spectrometry and MRI for assessing brain damage. RESULTS: Out of 180 eligible patients 110 were randomized, 57 (51.8%) to topiramate and 53 (48.2%) to placebo. No differences in the perinatal or postnatal variables were found. The topiramate group exhibited less seizure burden in the first 24 h of hypothermia (topiramate, n = 14 [25.9%] vs. placebo, n = 22 [42%]); needed less additional medication, and had lower mortality (topiramate, n = 5 [9.2%] vs. placebo, n = 10 [19.2%]); however, these results did not achieve statistical significance. Topiramate achieved a therapeutic range in 37.5 and 75.5% of the patients at 24 and 48 h, respectively. A significant association between serum topiramate levels and seizure activity (p < 0.016) was established. No differences for oxidative stress, energy-related metabolites, or MRI were found. CONCLUSIONS: Topiramate reduced seizures in patients achieving therapeutic levels in the first hours after treatment initiation; however, they represented only a part of the study population. Our results warrant further studies with higher loading and maintenance dosing of topiramate.
