Pharmacological Therapy of Gastroesophageal Reflux in Preterm Infants
Luigi Corvaglia,Caterina Monari,Silvia Martini,Arianna Aceti,Giacomo Faldella
Gastroenterology Research and Practice , 2013, DOI: 10.1155/2013/714564
Abstract: Although gastroesophageal reflux (GER) is a very common phenomenon among preterm infants, its therapeutic management is still an issue of debate among neonatologists. A step-wise approach should be advisable, firstly promoting nonpharmacological interventions and limiting drugs to selected infants unresponsive to the conservative measures or who are suffering from severe GER with clinical complications. Despite of this, a concerning pharmacological overtreatment has been increasingly reported. Most of the antireflux drugs, however, have not been specifically assessed in preterm infants; moreover, serious adverse effects have been noticed in association to their administration. This review mainly aims to draw the state of the art regarding the pharmacological management of GER in preterm infants, analyzing the best piecies of evidence currently available on the most prescribed anti-reflux drugs. Although further trials are required, sodium alginate-based formulations might be considered promising; however, data regarding their safety are still limited. Few piecies of evidence on the efficacy of histamine-2 receptor blockers and proton pump inhibitors in preterm infants with GER are currently available. Nevertheless, a significantly increased risk of necrotizing enterocolitis and infections has been largely reported in association with their use, thereby leading to an unfavorable risk-benefit ratio. The efficacy of metoclopramide in GER’s improvement still needs to be clarified. Other prokinetic agents, such as domperidone and erythromycin, have been reported to be ineffective, whereas cisapride has been withdrawn due to its remarkable cardiac adverse effects. 1. Introduction Gastroesophageal reflux (GER) is very frequent in preterm infants. The incidence in those babies born before 34 weeks of gestation approximately amounts to 22% [1]. In the preterm population GER should not be usually considered a pathological phenomenon, as it might be promoted by a number of physiological factors. Among these, are included the supine posture, which enhances the migration of liquid gastric content through the looser gastroesophageal junction, the immature esophageal motility, which leads to a poor clearance of refluxate, and, eventually, the relatively abundant milk intakes [2]. The linkage between GER, apneas [3] and chronic lung disease is still controversial [4, 5]. In few cases, however, GER may be associated to clinical complications as, for instance, feeding problems, failure to thrive, esophagitis, and lung aspiration [6], thereby lengthening the hospital stay
Predictors of Full Enteral Feeding Achievement in Very Low Birth Weight Infants
Luigi Corvaglia, Maria Pia Fantini, Arianna Aceti, Dino Gibertoni, Paola Rucci, Dante Baronciani, Giacomo Faldella, on behalf of the “Emilia Romagna Perinatal Network”
PLOS ONE , 2014, DOI: 10.1371/journal.pone.0092235
Abstract: Background To elucidate the role of prenatal, neonatal and early postnatal variables in influencing the achievement of full enteral feeding (FEF) in very low birth weight (VLBW) infants and to determine whether neonatal intensive care units (NICUs) differ in this outcome. Methods Population-based retrospective cohort study using data on 1,864 VLBW infants drawn from the “Emilia-Romagna Perinatal Network” Registry from 2004 to 2009. The outcome of interest was time to FEF achievement. Eleven prenatal, neonatal and early postnatal variables and the study NICUs were selected as potential predictors of time to FEF. Parametric survival analysis was used to model time to FEF as a function of the predictors. Marginal effects were used to obtain adjusted estimates of median time to FEF for specific subgroups of infants. Results Lower gestational age, exclusive formula feeding, higher CRIB II score, maternal hypertension, cesarean delivery, SGA and PDA predicted delayed FEF. NICUs proved to be heterogeneous in terms of FEF achievement. Newborns with PDA had a 4.2 days longer predicted median time to FEF compared to those without PDA; newborns exclusively formula-fed had a 1.4 days longer time to FEF compared to those fed human milk. Conclusions The results of our study suggest that time to FEF is influenced by clinical variables and NICU-specific practices. Knowledge of the variables associated with delayed/earlier FEF achievement could help in improving specific aspects of routine clinical management of VLBW infants and to reduce practice variability.

Perceptions of the effects of clicker technology on student learning and engagement: a study of freshmen Chemistry students
Jenepher Lennox Terrion,Victoria Aceti
Research in Learning Technology , 2012, DOI: 10.3402/rlt.v20i0.16150
Abstract: While technology – in the form of laptops and cellphones – may be the cause of much of the distraction in university and college classrooms, some, including the personal or classroom response system (PRS/CRS) or clicker, also present pedagogical opportunities to enhance student engagement. The current study explored the reactions of students to clicker implementation in a large, introductory chemistry class. During the final class of the semester, 200 students in an introductory chemistry class responded to an attitudinal and informational student survey using both Likert-type and non-Likert type questions to evaluate their perception of the implementation of the clickers and their impact on student learning and engagement. The results demonstrated that, when implemented effectively, clickers contribute to greater student engagement and, ultimately, an opportunity for professors to enact best practices in higher education pedagogy. This study points to the importance of effective pedagogy in making clickers worthwhile.
The Many Forms and Functions of Long Term Plasticity at GABAergic Synapses
Arianna Maffei
Neural Plasticity , 2011, DOI: 10.1155/2011/254724
Abstract: On February 12th 1973, Bliss and Lomo submitted their findings on activity-dependent plasticity of glutamatergic synapses. After this groundbreaking discovery, long-term potentiation (LTP) and depression (LTD) gained center stage in the study of learning, memory, and experience-dependent refinement of neural circuits. While LTP and LTD are extensively studied and their relevance to brain function is widely accepted, new experimental and theoretical work recently demonstrates that brain development and function relies on additional forms of plasticity, some of which occur at nonglutamatergic synapses. The strength of GABAergic synapses is modulated by activity, and new functions for inhibitory synaptic plasticity are emerging. Together with excitatory neurons, inhibitory neurons shape the excitability and dynamic range of neural circuits. Thus, the understanding of inhibitory synaptic plasticity is crucial to fully comprehend the physiology of brain circuits. Here, I will review recent findings about plasticity at GABAergic synapses and discuss how it may contribute to circuit function. 1. Heterosynaptic Inhibitory Plasticity 1.1. Long-Term Potentiation Plasticity of GABAergic synapses onto excitatory neurons, in the form of long-term potentiation (LTPi) and/or depression (LTDi) of inhibitory postsynaptic potentials (IPSPs), was initially reported in layer 5 of the rodent primary visual cortex [1]. Following these pioneering studies, bidirectional inhibitory plasticity was observed in many areas of the brain—neonatal hippocampus [2], deep cerebellar nuclei [3, 4], lateral superior olive [5], brain stem [6], and onto dopaminergic neurons in the ventral tegmental area (VTA) [7, 8]. Although there are significant differences in the induction and expression mechanisms of high-frequency long-term inhibitory plasticity (HF-LTPi and HF-LTDi, Figure 1), some common features have been identified across several brain circuits. Most forms of HF-LTPi involve Ca2+-mediated signaling. The source of Ca2+ is specific to the inhibitory synapse: voltage-gated calcium channels (VGCC) in neonatal hippocampus (Figure 1(b), left panel) [9]; astrocytes in juvenile hippocampus [10]; postsynaptic intracellular stores in cortex (Figure 1(a), left panel) [11, 12]; activation of postsynaptic NMDA receptors in the VTA (Figure 1(c), left panel) [8]. In several systems, the induction of HF-LTPi and HF-LTDi depends on high-frequency activation of glutamatergic and GABAergic axons. Postsynaptic activation of glutamatergic receptors is often required for the induction of HF-LTPi, while
Educational models and concept of childhood in the Gaza Strip Educare a Gaza

Abstract: In 2008, R.E.C. (Remedial Education Centre, Gaza, Palestine) was carrying out the project “Promotion of the democratic process and active participation among young population in the Gaza Strip”, approved by the Europe Initiative for democracy and Human Rights, and financed by the European Union. The project included a research activity, “Educational models and concept of childhood in the Gaza Strip”. The research is an idea coming from the long-term collaboration, started in 2002, between EducAid (Italian Ngo, Rimini, Italy) and R.E.C. in the educational work with the vulnerable children in the Gaza Strip.Teachers, educators and parents play a fundamental role in the education of children and adolescents; therefore families, associations and schools should be places where children become aware of their rights as human beings, in order to become, one day, active citizens of a society that themselves can improve. It’s of fundamental importance the policy that institutions carry out (supporting families, schools and associations), because it guarantees a functional education system. We interfaced with the different faces of formal and informal education, and it was impossible not to have the sensation of being inside a big prison, not too big, if we think its size compared to one and a half million inhabitants, between a closed tall and gray wall, a sea hardly accessible due to embargo, and Erez, the check point of transit for Israel. No gas, no fuel, no electricity, yet children continue to go to school, the roads are crowded by pedestrians who are waiting for a taxi for hours under the sun, wondering if they can go to work. The potential of education and schooling represent non-violent weapons to defend peace, promote change, make children aware of their rights, begin to live their citizenship at school, at home, in the associations. Through the testimonies we realized how much these valuable potentials are in danger in the Gaza Strip, as indeed in many other places in the world where people are slaves to someone or something, and lose confidence, tighten up their minds, are afraid to change, to fight for transforming what the political, social, local and international system make difficult and overwhelming. In 2008, R.E.C.

Althea Gyles’ Symbolic (De)Codification of William Butler Yeats’ ‘Rose and Wind Poetry’
Arianna Antonielli
Studi Irlandesi : a Journal of Irish Studies , 2011,
Abstract: In 1897, Yeats’s The Secret Rose was published in London by Lawrence & Bullen, while two years later, in 1899, the London editor Elkin Mathews published The Wind Among the Reeds. Both volumes are extremely interesting, not only for their acknowledged poetical value but also for their material worth. This is due to their elaborate designs: gold stamps on the spine and cover 1897 edition of the Secret Rose and intertwining reeds on The Wind Among the Reeds cover. Both were done by the Irish artist Althea Gyles (1867-1949). Gyles was frequently described by Yeats as a “symbolic artist” producing a “symbolic art” (Memoirs: Autobiography – A First Draft, 1972). Her paintings deeply influenced Yeats’s symbolical and imaginary system, to such a degree that they formed its perfect iconic counterpart. Following this hypothesis, Antonielli concentrates on Yeats’s main esoteric topoi, symbols and images emerging from the poems in The Secret Rose and The Wind Among the Reeds, and on their ‘translation’ into Althea Gyles’s iconic visions and artistic output. She examines how Yeats’s poems were clarified or further complicated by Gyles’s corresponding designs and how Yeats and Gyles, through their own peculiar artistic expressions, exemplified a shared symbolic vision of phenomenal reality.
The Rhyme of the Flying Bomb di Mervyn Peake: 125 quartine sul Blitz di Londra
Arianna Antonielli
LEA : Lingue e Letterature d'Oriente e d'Occidente , 2013,
Abstract: This essay addresses Mervyn Peake’s own memories of the Second World War Blitz and their migration into the poetical form of a ballad, The Rhyme of the Flying Bomb, composed in 1947. Abounding with Catholic symbolism, allegories and sea imagery, the poem tells the story of a sailor escaping from London bombing raids and his rescue of a new-born babe from a “golden drain”. The subsequent dialogue between the two protagonists reveals the fragile human side of the sailor and the divine prophetical power of the infant. Their former roles of saviour and rescued finally appear to be both spiritually and physically inverted. Written in alternating rhymes, the poem emphasizes Peake’s strong faith in humanity’s capacity to perform acts of love, despite living “at the height of a world at war”.
Ripensare l’11 Settembre con Derrida: Tra evento e autoimmunità
Arianna Marchente
Altre Modernità , 2011,
Abstract: In a way, after the September 11th terrorist attack, we have all had the feeling that we witnessed a real major event. However, the notion of event itself is semantically problematic. The 10th anniversary of this date offers us the opportunity to interrogate ourselves with a new question: was this indeed an event? To what extent? This is the very question which opens Jacques Derrida’s interview, undertaken by Giovanna Borradori in New York a few days after the attack. Indeed the French philosopher Derrida provides us with deep insights into the notion of event, its underpinnings and semantic roots. To a certain extent September 11th seems to be an event; indeed, how otherwise could it have given such a strong impression of being so? On the other hand however, it seems not to have been an event, in that it does not correspond to the Derridian definition of “event” as a surprise, as something totally unpredictable. September 11th - Derrida claims- was predictable and it’s not by chance that the US had created institutions such as the CIA or the NSA to defend themselves from this kind of threat. Nevertheless in understanding September 11th as something other than an event, we are forced to struggle with the question why was it that we first had the impression it was an event and why did it have such a strong impact on us? We are therefore confronted with two new important questions. The first leads us to reflect on the role that the media played with respect to September 11th. What would September 11th have been –Derrida asks himself- without TV? The second question concerns the auto-immune nature of this event, which explains its traumatic effect and stands as an emblem of that auto-immunity, which is the fundamental characteristic of present times, in this era of globalisation.
The political economy of Turkey-EU customs union after the treaty of Lisbon: A Reappraisal
Arianna Catalano
Interdisciplinary Political Studies , 2011,
Abstract: This article analyses the European Union’s (EU) trade policy highlighting the gradual shift towards a more penetrating EU Free Trade Agreements (FTAs) policy and institutional changes brought about by the Treaty of Lisbon and their impact on trade policy’s functioning. Emphasizing Turkey’s changing trade patterns and stressing the growing salience of non-EU trade partners, the article opens up a debate on the rationale of current Customs Union. The analysis brings to the understanding of the on-going cases of trade deflection negatively affecting Turkish economy and the drawbacks arisen from the EU’s changing FTA policy. Finally, the political and technical aspects of Turkey’s accession process are discussed to shed further light on the current and future meaning behind today’s Customs Union.
