Breastfeeding and Allergic Diseases: What's New?
Asthma and other allergic disorders, such as atopic dermatitis and food allergies, are common chronic health problems in childhood. The rapid rise in the prevalence of these conditions registered over the last few decades has stressed the need to identify the modifiable risk factors associated with the development of these diseases. Breast milk, recognized as the gold standard for healthy growth and development of the newborn, is one of the major factors associated with a lower incidence of allergic and infectious diseases in childhood and young adulthood. Although the underlying mechanisms for these effects are not well understood, breastfeeding leads to immune system maturation. In this narrative review, we summarize existing evidence on breastfeeding and human milk composition in relation to allergic disease prevention or development
Breast milk: more than just nutrition!
From an evolutionary and nutritional standpoint, exclusive human milk feeding for the first 6 months of life, with continued breastfeeding for 1 to 2 years of life, is recognized as the gold standard nourishment for the infant: it is a species-specific food, with a composition designed by nature to better respond to the biological and psychological needs of the newborn/infant. Human milk contains many hundreds of bioactive molecules that protect newborn against infection and inflammation and contribute to immune maturation, organ development, and healthy microbial colonization. Compared with formula feeding, breastfeeding has been associated with decreased morbidity and mortality in infants and to lower incidence of gastrointestinal infections and inflammatory, respiratory and allergic disease. Here, we briefly review the nutritional and functional composition of human milk and provide an overview of its varied bioactive factors
Neonatal hypoxic-ischemic encephalopathy after acute carbon monoxide intoxication during pregnancy. A case report and brief review of the literature
Carbon monoxide (CO) poisoning during pregnancy is a rare occurrence, associated with high maternal and fetal mortality rates. As CO can cross the placenta, leading to intrauterine hypoxia, CO intoxication can result in neurological sequelae and neurologic complications in fetuses who survive. We report a case of a preterm newborn acutely exposed to CO in-utero and delivered by emergent cesarean section at the 31st week of gestation due to the severe burns suffered by the mother following an indoor boiler explosion. As CO has serious adverse effects both on the mother and fetus, it is important to recognize and treat poisoning in a timely manner. Despite maternal blood CO levels, CO intoxication at critical stage of central nervous system development can lead to hypoxic-ischemic lesions, thus interdisciplinary care and follow up for these patients are mandatory
Fever and Challenging Cutaneous Mimicked-Urticaria Reaction to Amoxicillin-Clavulanate in two Children
Proprietà immunomodulanti dei nutraceutici nelle infezioni virali
In recent years, there has been a growing interest in the possibility of using some nutritional supplements with antimicrobial and immunomodulating activity in the prevention and treatment of viral infections, particularly in the respiratory system. The antiviral and immunomodulating role of vitamin D, zinc, lactoferrin, vitamin A and polyphenols (in particular, resveratrol) has been the subject of both clinical and preclinical studies, which have allowed both to define the properties of these molecules and, in some cases, to increase understanding of the mechanisms underlying the regulation of the immune response. The actions of these nutraceuticals on the immune system are extremely complex, and include both direct interactions with cellular elements and interference with the synthesis and biological action of its main soluble mediators, while the antiviral properties derive both from direct interference with the replication of pathogens that from the ability to stimulate the immune and adaptive response against the virus itself. Despite the marked increase in the understanding of the mechanisms of action of these molecules, clinical evidence is still limited, therefore making further studies necessary to define more specifically their clinical applications in the management of respiratory infections
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
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
