Trends in hospital consumption of analgesics after the implementation of a pain performance improvement plan / Tendências no consumo hospitalar de analgésicos após a implantação de plano de melhoria do controle da dor

Abstract Background: Pain management committee established a pain performance improvement plan in 2012. Objectives: The aim of the study was to assess the trends in analgesic consumption in a tertiary teaching hospital and the associated economic impact. Methods: A descriptive, retrospective study was conducted between 2011 and 2015. The analysis included: anti-inflammatory and antirheumatic products non-steroids, opioid analgesics and other analgesics and antipyretics. Data are converted into DDD/100 bed-days to analyze consumption trends. Main outcome measure: assessment of the analgesic consumption after the implementation of a pain performance improvement plan. Results: Overall, non-steroidal anti-inflammatory and antirheumatic products consumption decreased in 24.8 DDD/100 bed-days (-28.3%), accounting for most of the total analgesic consumption decrease (-13%) and total cost (-44.3%). Opioid consumption increased markedly from 22.3 DDD/100 bed-days in 2011 to 26.5 DDD/100 bed-days in 2015 (+18.9%). In 2011, the most consumed opioid was morphine (8.6 DDD/100 bed-days). However, there was an increasing trend in fentanyl consumption (from 8.1 to 12.1 DDD/100 bed-days in 2015), which resulted in fentanyl replacing morphine from the most consumed opioid in 2015 (12.1 DDD/100 bed-days). In 2015, the group of other analgesics and antipyretics represented 46.2% of the total analgesic consumption. Acetaminophen was the most commonly consumed analgesic drug (53.2 DDD/100 bed-days in 2015) and had the highest total cost, it represented 55.4% of the overall cost in 2015. Conclusion: Opioid consumption showed an increasing trend during the 5 year period, with fentanyl replacing morphine as the most used opioid. In general, analgesics diminished use was due to the decreasing trend of consumption of non-steroidal anti-inflammatory and antirheumatic products.

Resumo Justificativa: A Comissão para o Manejo da Dor estabeleceu um plano de melhoria no controle da dor em 2012. Objetivo: Avaliar as tendências do consumo de analgésicos em um hospital de ensino terciário e o impacto econômico associado. Métodos: Estudo descritivo, retrospectivo, feito entre 2011 e 2015. A análise incluiu: produtos anti-inflamatórios e antirreumáticos não esteroides, analgésicos opioides e outros analgésicos e antipiréticos. Os dados foram convertidos em DDD/100 leitos-dia para analisar as tendências de consumo. Principal medida do desfecho: avaliação do consumo de analgésicos após o estabelecimento de um plano de melhoria no controle da dor. Resultados: O consumo total de produtos anti-inflamatórios e antirreumáticos não esteroides diminuiu em 24,8 DDD/100 leitos-dia (-28,3%), representando a maior parte da redução total do consumo de analgésicos (-13%) e o custo total (-44,3%). O consumo global de opioides aumentou acentuadamente de 22,3 DDD/100 leitos-dia em 2011 para 26,5 DDD/100 leitos-dia em 2015 (+18,9%). Em 2011, o opioide mais consumido foi a morfina (8,6 DDD/100 leitos-dia). No entanto, houve uma tendência crescente no consumo de fentanil (de 8,1 para 12,1 DDD/100 leitos-dia em 2015), o que resultou na substituição de morfina por fentanil como o opioide mais consumido em 2015 (12,1 DDD/100 leitos-dia). Em 2015, o grupo dos outros analgésicos e antipiréticos representou 46,2% do consumo total de analgésicos. Acetaminofeno foi o analgésico mais consumido (53,2 DDD/100 leitos-dia em 2015) e teve o maior custo total, representou 55,4% do custo total em 2015. Conclusão: O consumo de opioides mostrou uma tendência crescente durante o período de cinco anos, fentanil substituiu morfina como o opioide mais usado. Em geral, o uso diminuído de analgésicos foi devido à tendência decrescente do consumo de produtos anti-inflamatórios e antirreumáticos não esteroides.

Less invasive beractant administration in preterm infants: a pilot study

OBJECTIVES: The aims of this study were to assess the efficacy and feasibility of a new, less invasive surfactant administration technique for beractant replacement using a specifically designed cannula in preterm infants born at <32 weeks of gestation and to compare short- and long-term outcomes between this approach and standard treatment, consisting of intubation, administration of surfactant and early extubation to nasal continuous positive airway pressure. METHOD: This was a single-center, prospective, open-label, non-randomized, controlled pilot study with an experimental cohort of 30 patients treated with less invasive surfactant administration and a retrospective control group comprising the 30 patients most recently treated with the standard approach. Beractant (4 ml/kg) was administered as an exogenous surfactant in both groups if patients on nasal continuous positive airway pressure during the first three days of life were in need of more than 30% FiO2. Clinicaltrials.gov: NCT02611284. RESULTS: In the group with less invasive surfactant administration, beractant was successfully administered in all patients. Thirteen patients (43.3%) in the group with less invasive surfactant administration required invasive mechanical ventilation for more than 1 hour during the first 3 days of life, compared with 22 (73%) in the control group (p<0.036). The rate of requiring invasive mechanical ventilation for more than 48 hours was similar between the infants in the two groups (46% vs. 40%, respectively). There were no differences in other outcomes. CONCLUSION: The administration of beractant (4 ml/kg) using a less invasive surfactant administration technique with a specifically designed cannula for administration is feasible. Moreover, early invasive mechanical ventilation exposure is significantly reduced by this method compared with the strategy involving intubation, surfactant administration and early extubation.

Initial respiratory management in preterm infants and bronchopulmonary dysplasia

BACKGROUND: Ventilator injury has been implicated in the pathogenesis of bronchopulmonary dysplasia. Avoiding invasive ventilation could reduce lung injury, and early respiratory management may affect pulmonary outcomes. OBJECTIVE: To analyze the effect of initial respiratory support on survival without bronchopulmonary dysplasia at a gestational age of 36 weeks. DESIGN/METHODS: A prospective 3-year observational study. Preterm infants of <32 weeks gestational age were classified into 4 groups according to the support needed during the first 2 hours of life: room air, nasal continuous positive airway pressure, intubation/surfactant/extubation and prolonged mechanical ventilation (defined as needing mechanical ventilation for more than 2 hours). RESULTS: Of the 329 eligible patients, a total of 49 percent did not need intubation, and 68.4 percent did not require prolonged mechanical ventilation. At a gestational age of 26 weeks, there was a significant correlation between survival without bronchopulmonary dysplasia and initial respiratory support. Preterm infants requiring mechanical ventilation showed a higher risk of death and bronchopulmonary dysplasia. After controlling for gestational age, antenatal corticosteroid use, maternal preeclampsia and chorioamnionitis, the survival rate without bronchopulmonary dysplasia remained significantly lower in the mechanically ventilated group. CONCLUSIONS: In our population, the need for more than 2 hours of mechanical ventilation predicted the development of bronchopulmonary dysplasia in preterm infants with a gestational age >26 weeks (sensitivity =89.5 percent and specificity = 67 percent). The need for prolonged mechanical ventilation could be an early marker for the development of bronchopulmonary dysplasia. This finding could help identify a target population with a high risk of chronic lung disease. Future research is needed to determine other strategies to prevent bronchopulmonary dysplasia in this high-risk group of patients.

Genomic organization of nucleolin gene in carp fish: Evidence for several genes

The protein nucleolin, functionally involved in the main steps of ribosome biogenesis, is codified by a single copy gene in mammals. Here we report that at least three different genes codify for this protein in carp fish (Cyprinus carpio). This is the first description of the genomic organization of nucleolin in a teleost. The carp nucleolin gene includes 8.8 kb and contains 16 exons. Promoter cis regulatory elements are similar to constitutive genes, i.e., a putative TATA box, three G/C boxes, and three pyrimidine-rich boxes. As in other species, carp nucleolin gene introns host three snoRNA codifying sequences: U23 from the H/ACA family and two C/D box snoRNAs, U20 and U82. Both U20 and U82 span a complementary sequence with carp 18S rRNA. Additionally, we identified two cDNAs coding for nucleolin, confirming the existence of several nucleolin genes in carp. Amino acid-derived sequence from carp cDNAs differ from mammal protein because they span additional acidic domains at the amino end, whose functional significance remains unclear. We performed amino acid sequence comparison and phylogenetic analyses showing that the three isoforms of carp nucleolin, which we describe herein, cluster in two groups. cNUC1 probably diverges from cNUC2 and cNUC3 as result of ancestral fish-specific genome duplication, indeed C. carpio is a tetraploid fish.

Estudio leucocitario en animales de laboratorio infectados con virus de encefalitis equina venezolana / Leucocitary study in laboratory animals infected with venezuelan equine encephalitis virus

Se estudió el número de glóbulos blancos y fórmula leucocitaria en animales de laboratorio tales como ratones, ratas y conejos antes y después de producirles una infección experimental aguda con el virus de la Encefalitis equina Venezolana. Se observó una leucopenia que varió de acuerdo a la sensibilidad de la especie animal. Las fórmulas leucocitarias presentaron variaciones, acompañadas de células atípicas las cuales persistieron hasta el final de la infección. Se observó también una vacuolización celular que alcanzó al 6 por ciento y que no estuvo presente nunca en los controles. Los conejos presentaron una eosinofilia que abarcó hasta un 36 por ciento en su fórmula leucocitaria poco antes de morir. Algunas ratas sobrevivieron y al cabo de 14 días presentaron títulos de anticuerpos inhibidores de la hemaglutinación entre 1/80-1/160, lo cual indica su resistencia a la infección viral
