    Management of pleural drainage

    No full text
    In the neonatal population, pleural effusion and particularly tension pneumothorax can be a deadly situation. Pneumothorax occurs more often in the neonatal period that any other time of life. Tension pneumothorax can result in very high pressures within the pleural space, collapsing the lung on the involved side and resulting in immediate hypoxia, hypercapnia and subsequent circulatory collapse. For these reasons, the ability to recognize, understand and treat these pathologies is essential for neonatal health and a good outcome. Neonates have many factors that can contribute to. these problems. These include respiratory distress syndrome, mechanical ventilation, sepsis, pneumonia, aspiration of meconium, congentital malformation, hydrothorax, congenital or acquired chylothorax. The diagnosis can be made by clinical examination, transillumination (pneumothorax) and chest x-ray. Besides, lung ultrasound constitutes a visual medicine and provides a transparent approach to the acutely ill patient, newborn included, guiding diagnosis, management and care. Newborns with moderate to severe symptoms and those receiving positive pressure ventilation require tube thoracostomy. If a tension pneumothorax is suspected, emergency needle decompression in the second intercostal space in the midclavicular line is required. In this article, we describe the management of tube thoracostomy using trocar tubes or pigtail catheters. Besides, we pay attention to the use of pain control for neonates undergoing painful procedures such as chest tube insertion

    Neurally adjusted ventilatory assist: a new approach to mechanically ventilated infants

    Neurally adjusted ventilator assist (NAVA) is a new mode of partial ventilatory support, in which neural inspiratory activity is monitored through the continuous esophageal recording of the electrical activity of the diaphragm. Assistance is triggered and cycled off in according to this signal and is delivered in proportion to its intensity. NAVA can improve patient-ventilator synchrony while maintaining spontaneous breathing. Small preliminary studies have shown that NAVA can be successfully used also in term and preterm infants, being safe and well tolerated. However, much additional work is still needed before NAVA can be recommended in the everyday practice of the neonatologist

    Going Beyond Counting First Authors in Author Co-citation Analysis

    The present study examines one of the fundamental aspects of author co-citation analysis (ACA) - the way co-citation counts are defined. Co-citation counting provides the data on which all subsequent statistical analyses and mappings are based, and we compare ACA results based on two different types of co-citation counting - the traditional type that only counts the first one among a cited work's authors on the one hand and a non-traditional type that takes into account the first 5 authors of a cited work on the other hand. Results indicate that the picture produced through this non-traditional author co-citation counting contains more coherent author groups and is therefore considerably clearer. However, this picture represents fewer specialties in the research field being studied than that produced through the traditional first-author co-citation counting when the same number of top-ranked authors is selected and analyzed. Reasons for these effects are discussed

    Variations on the Author

    “Variations on the Author” discusses two of Eduardo Coutinho’s recent films (Um Dia na Vida, from 2010, and Últimas Conversas, posthumously released in 2015) and their contribution to the general question of documentary authorship. The director’s filmography is characterized by a consistent yet self-effacing form of authorial self-inscription: Coutinho often features as an interviewer that rather than express opinions propels discourses; an interviewer that is good at listening. This mode of self-inscription characterizes him as an author who is not expressive but who is nonetheless markedly present on the screen. In Um Dia na Vida, however, Coutinho is completely absent form the image, while Últimas Conversas, on the contrary, includes a confessional prologue that moves the director from the margins to the center of his films. This article examines the ways in which these works stand out in the filmography of a director who offers new insights into the notion of cinematic authorship

    Intermittently Scanned and Continuous Glucose Monitor Systems: A Systematic Review on Psychological Outcomes in Pediatric Patients

    No full text
    Aim: To explore the impact of real-time continuous glucose monitoring (rtCGMs) or intermittently scanned/viewed CGM (isCGM) on psychological outcomes in children and caregivers, and to grade the level of evidence. Method: Systematic review of the literature from PubMed, Embase, Cochrane Library, Web of Science, CINAHL, Nursing reference center, Up to date, Google Scholar, and PsycINFO databases. The studies selected used validated questionnaires for investigating the psychological outcomes. We applied GRADE (Grading of Recommendations Assessment, Development and Evaluation) to rank the quality of a body of evidence. Results: A total of 192 studies were identified in the initial search and after the process of evaluation 25 studies were selected as appropriate to be included in this systematic review. We found in moderate quality studies that isCGM in adolescents can improve diabetes related distress, family conflicts, fear of hypoglycemia, and quality of life, while depression, anxiety, and quality of sleep have not yet been evaluated by validated questionnaires. In moderate—high quality studies, rtCGM technology does not impact on diabetes burden, diabetes specific family conflict, and depressive symptoms. The effect on fear of hypoglycemia, sleep quality, and anxiety is still debated and RCT studies powered to find significant results in psychological outcomes are lacking. RtCGM increases satisfaction and quality of life in parents and patients wearing rtCGM. Conclusion: these data present an interesting point to consider when families are deciding whether or not to start CGM use, choosing between rtCGM to reach a tighter metabolic control, or isCGM which allows greater benefits on psychological outcomes

    Appropriate Similarity Measures for Author Cocitation Analysis

    We provide a number of new insights into the methodological discussion about author cocitation analysis. We first argue that the use of the Pearson correlation for measuring the similarity between authors’ cocitation profiles is not very satisfactory. We then discuss what kind of similarity measures may be used as an alternative to the Pearson correlation. We consider three similarity measures in particular. One is the well-known cosine. The other two similarity measures have not been used before in the bibliometric literature. Finally, we show by means of an example that our findings have a high practical relevance.information science;Pearson correlation;cosine;similarity measure;author cocitation analysis

    Atherogenic lipid profile in patients with Niemann-Pick disease type B: What treatment strategies?

    No full text
    Niemann-Pick disease (NPD) type A and type B are part of the spectrum disease of the acid sphingomyelinase deficiency (ASMD). Plasma lipid abnormalities are frequently associated with both NPD-A and NPD-B, and include decreased high-density lipoprotein cholesterol (HDL-C), increased low-density lipoprotein cholesterol (LDL-C), and hypertriglyceridemia. The atherogenic lipid profile has been associated to early atherosclerotic vascular disease and coronary artery disease in NPD-B patients. Thus, early treatment of dyslipidemia in these patients is advisable. We present here a pediatric case of NPD-B with an atherogenic lipid profile not responding to lifestyle changes, low fat diet, and daily supplementation with plant sterols. We reviewed the existing literature about the treatment strategies for dyslipidemia in ASMD patients, with a special focus on the pediatric age. Finally, we speculated on the mechanisms underlying dyslipidemia in this disorder. The clinical experiences in lipid-lowering strategies in NPD-B patients are limited, in particular in the pediatric age. Olipudase alfa appears as the most promising candidate for improving lipid profile. Since olipudase alfa is not yet approved and, due to its costs, it will probably not be available for all patients worldwide, further research is needed to broaden our knowledge on this clinical need and to evaluate the efficacy and the long-term effects of lipid-lowering agents in ASMD patients. A deep understanding of the pathophysiology of dyslipidemia in ASMD may promote the identification of new targets and support the identification of new therapeutic strategies
