Changes in Patent Ductus Arteriosus Treatment Strategy and Respiratory Outcomes in Premature Infants.

OBJECTIVE: To evaluate whether change in patent ductus arteriosus (PDA) management strategies over time had an impact on respiratory outcomes in premature infants. STUDY DESIGN: Prospectively collected data were included from all preterm infants born at 23-30 weeks gestational age with PDA admitted to the Children's Hospital of the University of Miami/Jackson Memorial Medical Center from January 1, 2005 to December 31, 2007 (epoch 1) and January 1, 2011 to December 31, 2015 (epoch 2). The 2 epochs were compared for approach with PDA diagnosis and subsequent management strategies and respiratory outcomes. RESULTS: Significantly fewer infants were treated for PDA in epoch 2 (54%) compared with epoch 1 (90%). Multivariable logistic regression analysis demonstrated that infants in epoch 2, with later PDA diagnosis and less frequent PDA treatment, had greater odds of bronchopulmonary dysplasia (BPD), composite of BPD or death, and more treatment with postnatal steroids than in epoch 1. CONCLUSIONS: The change in approach to diagnosis and management of PDA, from a more proactive and aggressive approach during the earlier epoch 1 to a more expectant approach during the subsequent epoch 2, was associated with worse respiratory outcomes, including increase in BPD and in BPD or death.

DIFFERENT SCORING SYSTEMS IN ACUTE ALCOHOLIC PANCREATITIS: WHICH ONE TO FOLLOW? AN ONGOING DILEMA.

BACKGROUND: Acute pancreatitis is a common disorder in medical practice. In recent times, management has changed drastically with majority of decisions like intravenous antibiotics, negative suction with Ryle's tube and surgical interventions like necrosectomy etc based on severity of the disease. There are different scores in use to assess severity of disease but the relative efficacy has remained a debatable subject. OBJECTIVE: The present study was thus done to investigate the predictive accuracy of different scoring systems in acute pancreatitis. METHODS: Fifty patients of acute pancreatitis admitted in medicine ward of Pt. B.D. Sharma PGIMS, Rohtak, India, were taken for study after fulfilling eligibility criteria. These patients were investigated at admission and followed up prospectively. The severity of pancreatitis was classified for each of these patients as per Revised Atlanta System of Classification. Commonly used scoring systems pertaining to acute pancreatitis, viz, BISAP, Ranson, APACHE II and modified computed tomography severity index (CTSI) were calculated. Subsequently these scores were then correlated with severity, presence of organ failure, occurrence of local complications and final outcome of the patients. RESULTS: Out of 50 patients, etiology was chronic alcohol intake in all but one with idiopathic pancreatitis. The mean age of the study population was 42.06±13.27 years. 32% of these patients had pancreatic necrosis, 40% had peripancreatic collections. 56% of them had mild acute pancreatitis, 24% had moderately severe acute pancreatitis, while 20% had severe acute pancreatitis. APACHE II had the highest accuracy in predicting severity, organ failure and fatal outcomes. As far as these parameters were concerned, the negative predictive values of BISAP score were also considerable. Modified CTSI score was accurate in predicting local complications but had limited accuracy in other predictions. CONCLUSION: APACHE II emerged as most reliable scoring system followed by BISAP and Ranson in management of the patients with acute pancreatitis. But in constraints of time and resources, even BISAP score with its significant negative predictive values served as a valuable tool for assessing and managing these patients.

RESUMO CONTEXTO: A pancreatite aguda é uma desordem comum na prática médica. Nos últimos tempos, sua gestão mudou drasticamente com a maioria das decisões tomadas baseadas na gravidade da doença, como administração de antibióticos intravenosos, sucção negativa com o tubo de Ryle ou intervenções cirúrgicas como necrosectomia, etc. Há diferentes escores em uso para avaliar a gravidade da doença, mas a eficácia relativa manteve-se um assunto discutível. OBJETIVO: O presente estudo foi assim realizado para investigar a acurácia preditiva de diferentes sistemas de pontuação na pancreatite aguda. MÉTODOS: Foram selecionados 50 pacientes com pancreatite aguda admitidos na enfermaria de medicina de Pt. B.D. Sharma PGIMS, Rohtak, Índia, e foram considerados para estudo após o cumprimento dos critérios de elegibilidade. Estes pacientes foram investigados na admissão e seguidos prospectivamente. A severidade da pancreatitie foi classificada para cada um destes pacientes pelo sistema de classificação Atlanta revisado. Os sistemas de pontuação comumente usados pertencentes à pancreatite aguda, ou seja, BISAP, Ranson, APACHE II e CTSI modificado foram calculados. Posteriormente, esses escores foram correlacionados com a severidade, presença de falência de órgãos, ocorrência de complicações locais e desfecho final dos pacientes. RESULTADOS: Dos 50 pacientes, a ingestão crônica de álcool foi a etiologia em todos, exceto em um com pancreatite idiopática. A média de idade da população estudada foi de 42,6±13,27 anos. Destes pacientes, 32% apresentavam necrose pancreática, 40% apresentavam coleções peripancreáticas, 56% apresentavam pancreatite aguda leve, 24% apresentavam pancreatite aguda moderadamente grave, enquanto 20% apresentavam pancreatite aguda grave. O APACHE II teve maior precisão em prever a severidade, a falha do órgão e resultados fatais. No que diz respeito a esses parâmetros, os valores preditivos negativos do escore BISAP também foram consideráveis. A contagem modificada de CTSI foi exata em prever complicações locais, mas teve a exatidão limitada em outras predições. CONCLUSÃO: O APACHE II emergiu como o sistema de pontuação mais confiável seguido por BISAP e Ranson na gestão dos pacientes com pancreatite aguda. Mas em condicionantes do tempo e dos recursos, mesmo a Pontuação do BISAP com seus valores preditivos negativos significativos, serviu como uma ferramenta valiosa para avaliar e administrar esses pacientes.

Early Caffeine and Weaning from Mechanical Ventilation in Preterm Infants: A Randomized, Placebo-Controlled Trial.

OBJECTIVE: To evaluate in a randomized, double-blind, placebo-controlled trial the effect of early caffeine on the age of first successful extubation in preterm infants. STUDY DESIGN: Preterm infants born at 23-30 weeks of gestation requiring mechanical ventilation in the first 5 postnatal days were randomized to receive a 20 mg/kg loading dose followed by 5 mg/kg/day of caffeine or placebo until considered ready for extubation. The placebo group received a blinded loading dose of caffeine before extubation. RESULTS: Infants were randomized to receive caffeine (n = 41) or placebo (n = 42). Age at first successful extubation did not differ between early caffeine (median, 24 days; IQR, 10-41 days) and control groups (median, 20 days; IQR, 9-43 days; P = .7). An interim analysis at 75% enrollment showed a trend toward higher mortality in 1 of the groups and the data safety and monitoring board recommended stopping the trial. Unblinded analysis revealed mortality did not differ significantly between the early caffeine (9 [22%]) and control groups (5 [12%]; P = .22). CONCLUSIONS: Early initiation of caffeine in this group of premature infants did not reduce the age of first successful extubation. A nonsignificant trend toward higher mortality in the early caffeine group led to a cautious decision to stop the trial. These findings suggest caution with early use of caffeine in mechanically ventilated preterm infants until more efficacy and safety data become available.

Comparison of composition and absorption of sugarcane policosanols.

Policosanols (PC) exist as very-long-chain alcohols derived from sugarcane currently used in many countries as a cholesterol-lowering therapy. PC purity and relative percentage composition have been suggested as primary reasons why the original Cuban PC (OPC) supplements possess lipid-lowering efficacy. The purpose of the present study was, first, to compare the relative percentage purity and PC composition of both OPC and alternative sources of PC (APC). A second objective was to feed Syrian hamsters a diet containing 0.275 mg PC/g of either the OPC or an APC product (APC1) and compare subsequent tissue, plasma and faecal PC levels. Five animals from the APC1 dietary group received a diet containing ten times the original amount of PC. Results indicate that the APC formulations have a composition that is highly consistent with the OPC supplement, with octacosanol being present within the cited 60-70 % range. PC were undetectable in the small intestine, liver, adipose or plasma in animals fed either source. Hamsters fed OPC excreted octacosanol (C28) more rapidly (P < 0.05) than hamsters receiving APC1. If the cholesterol-lowering efficacy of PC mixtures is dependent on their purity and composition, then sugarcane-derived APC products should possess similar therapeutic properties as the OPC supplement.
