Emergent factors in Eating Disorders in childhood and preadolescence
We have reviewed the literature related to the current advances in comprehension of Eating Disorders (ED) in childhood and preadolescence. The state of art regarding the psychodynamic models concerning the onset of ED are explained. DSM-IV and ICD-10 criteria are discussed, pointing out their little value in the characterization of early eating difficulties. Historic and new diagnostic classifications are displayed in detail. We provided a clearer description of subclinical patterns. Finally we focus on the key role of the paediatrician in detecting and managing parental concerns regarding feeding
Effects of Dietary Quebracho Tannin on Performance Traits and Parasite Load in an Italian Slow-Growing Chicken (White Livorno Breed)
Tannins have shown numerous biological activities and are very appreciated in food animal production, especially for their antimicrobial, antiparasitic, antioxidant, anti-inflammatory and antivirus effects. The aim of the present study was to evaluate the effect of two levels of dietary Quebracho tannin (QT) on growth and performance traits, and possible effects on intestinal parasite load in Italian White Livorno pullets. A 140-day trial was carried out on 180 35-day-old females, fed on two levels of dietary QT inclusion: 0%, 1% and 2%. Birds were reared under free-range conditions. Dietary Quebracho tannin may be used up to 1% in growing female White Livorno chickens without any adverse effects. The results observed in this study on the use of dietary QT at 2% might have not reflected the real effect on performance traits due to the initial inclusion of dietary QT at 3%. Nevertheless, by reducing QT to 2%, a progressive normalization of body weight gain, feed intake and feed conversion ratio was observed, resulting in compensatory growth. QT was demonstrated to drastically reduce fecal outputs of Nematodes eggs (Ascaridia spp. and Heterakis spp.) and Coccidia oocytes (Eimeria spp.). The inclusion of 2% produced highly dry droppings
I disturbi del comportamento alimentare (DCA): riflessioni e problematiche
Eating disorders (ED) are an important cause of physical and psychosocial morbidity in adolescents and young adults, characterized by aberrant patterns of eating behavior and weight regulation and by disturbances in attitudes towards weight and perception of body shape. This article, through the description of a clinical case, focuses on the complexities of clinical management and on the importance of an integrated approach
ECAL Front-End Monitoring in the CMS experiment
The CMS detector at LHC is equipped with a high precision lead tungstate crystal electromagnetic calorimeter (ECAL). The front-end boards and the photodetectors are monitored using a network of DCU (Detector Control Unit) chips located on the detector electronics. The DCU data are accessible through token rings controlled by an XDAQ based software component. Relevant parameters are transferred to DCS (Detector Control System) and stored into the Condition DataBase. The operational experience from the ECAL commissioning at the CMS experimental cavern is discussed and summarized
Overview of Native Chicken Breeds in Italy: Conservation Status and Rearing Systems in Use
The ongoing loss of domestic animal breeds around the world is occurring at an alarming rate. Thus, the registration and preservation of native breeds is of great importance. The aim of this study, which forms part of a conservation program, was to provide an overview of the conservation statuses of native Italian poultry breeds being reared by local breeders in Italy. The data collected by means of a census questionnaire demonstrate the low population sizes of these breeds in Italy and highlight the need for campaigns aimed at publicizing and promoting the benefits of native breeds with the goal of increasing population sizes. Identifying strategies to facilitate breedersâ access to pure breed birds is also essential, and would require collaborative efforts of university research centers, public entities, and breeders
Overview of Native Chicken Breeds in Italy: Small Scale Production and Marketing
The intensive use of high-performing strains in poultry production has led to the extinction
of several autochthonous chicken breeds and, consequently, loss of genetic variability. Interest in
saving biodiversity is growing rapidly and has become a major objective worldwide. The aim of this
study was to shed light on the production trends of native Italian poultry breeds and the related
market. A questionnaire, which asked about the production cycles, the number of animals and
table eggs produced per year and their retail prices was completed by 121 breeders across Italy. The
surveyed breeders were divided into two categories: breeders conducting an agrozootechnical farm,
referred to as âfarmersâ (F); and breeders keeping chickens as backyard poultry, referred to as âfancy
breedersâ (FB). Analysis of the data acquired indicated that animals were mainly slaughtered between
6 and 12 months of age, with F processing more animals per year. The same production trend was
observed for table eggs. The recorded retail prices of native chicken products were higher than
those for conventional products, but similar to those reported for valuable niche poultry products,
such as the Poulet de Bresse in France and organic eggs. Knowledge about these highly valuable
markets should be used to encourage the use of local breeds in alternative poultry farming and help
protect biodiversity
