Cardio-Pulmonary Parasitic Nematodes Affecting Cats in Europe: Unraveling the Past, Depicting the Present, and Predicting the Future
Donato Traversa,Angela Di Cesare
Frontiers in Veterinary Science , 2014, DOI: 10.3389/fvets.2014.00011
Abstract: Various cardio-pulmonary parasitic nematodes infecting cats have recently been fascinating and stimulating the attention of the Academia, pharmaceutical companies, and veterinary practitioners. This is the case of the metastrongyloids: Aelurostrongylus abstrusus and Troglostrongylus brevior, the trichuroid: Capillaria aerophila (syn. Eucoleus aerophilus), and the filarioid: Dirofilaria immitis. Apparently, these parasites have been emerging in several European countries, thus, gaining an important role in feline parasitology and clinical practice. Under a practical standpoint, a sound knowledge of the biological, epidemiological, and clinical impact of cardio-respiratory parasitoses affecting cats, in addition to a potential risk of introduction, establishment, and spreading of “new” parasites in Europe is mandatory in order to understand the present and future impact for feline medicine and to address new strategies of control and treatment. The purpose of the present article is to review the current knowledge of heartworm and lungworm infections in cats, discussing and comparing past and present issues, and predicting possible future scenarios.
Canine and feline cardiopulmonary parasitic nematodes in Europe: emerging and underestimated
Donato Traversa, Angela Di Cesare, Gary Conboy
Parasites & Vectors , 2010, DOI: 10.1186/1756-3305-3-62
Abstract: Nematodes affecting the cardiopulmonary system of dogs and cats have recently become the focus of increased attention from the scientific community due to their emergence in several European countries and the spread into previously non-endemic regions. This has been particularly the case for the metastrongyloids Aelurostrongylus abstrusus, Angiostrongylus vasorum and Crenosoma vulpis, the filarioid Dirofilaria immitis and the trichuroid Eucoleus aerophilus (syn. Capillaria aerophila). Indeed, the importance of infection with the heartworm (A. vasorum and D. immitis) and lungworm (A. abstrusus, C. vulpis and E. aerophilus) parasites in companion animals is heightened by the pathogenic potential of these nematodes, the challenges involved in diagnosis and (for some) their zoonotic potential.The reasons for the apparent emergence of cardiopulmonary parasitoses in pets are unknown but several factors such as global warming, changes in vector seasonal population dynamics and movements in animal populations, may play a role in the recent rise in reports of infection in the various countries of Europe. Most of these parasites have an indirect life cycle, thus requiring an intermediate host (i.e. biological vector) for their development. This is true for the gastropod-borne A. abstrusus, A. vasorum and C. vulpis and for the mosquito-transmitted D. immitis. Conversely, E. aerophilus may develop either directly in the environment or in earthworms acting as facultative intermediate hosts. Consequently, the likelihood for a dog or a cat becoming infected by a cardiopulmonary nematode depends not only on the presence of the vector(s) but also by their abundance and the prevalence of the infection. The occurrence of canine and feline heartworms and lungworms in different geographical areas is mainly influenced by the presence of competent gastropod and culicid species, with the exception of E. aerophilus, whose presence is guaranteed by the ubiquity of the earthworms and by the d
Assessment of wet weather impact on clam (Chamelea gallina) faecal contamination in the district of San Benedetto del Tronto (Italy)

Italian Journal of Food Safety , 2012, DOI: 10.4081/ijfs.2012.6.46
Abstract: Since 1998 clams (Chamelea gallina) from the production areas of the district of San Benedetto del Tronto (South Marche - Italy) have been periodically monitored to check the microbiological quality by the detection of the faecal indicator E. coli (MPN method). Results have been inconstant. They were not directly related to contamination sources identified by means of a Sanitary Survey. This one included a desk-based study of the physical, geographic, demographic and urban features of the district above and a shoreline survey to confirm or update previously identified sources. With regard to this, several authors found out that meteoric events, in particular rainfalls, increase faecal loading in marine coastal water. This study investigated the impact of rainfalls on E. coli values in clams from the district of San Benedetto del Tronto according to the sampling plan from 2002 to 2011. The study focused on rainfalls occurred until 4 days before mollusc sampling and set up E. coli values into satisfactory and unsatisfactory levels compared to the food safety limit of 230 MPN/100 g. Data were processed by a statistical tool, the Fisher’s exact test. Results revealed the association between precipitations and exceeding values of E. coli in clams collected from coastal waters of most populous areas to be statistically significant.
Mixed trichuroid infestation in a dog from Italy
Angela Di Cesare, Giuseppe Castagna, Silvana Meloni, Domenico Otranto, Donato Traversa
Parasites & Vectors , 2012, DOI: 10.1186/1756-3305-5-128
Abstract: In December 2011, a mixed infestation by T. vulpis, C. aerophila and C. boehmi was diagnosed in an asymptomatic dog living in central Italy. Morphometric and morphological findings and pictures of the eggs found at the copromicroscopic analysis are herein reported.The present work demonstrates that when trichuroid eggs are found in a faecal sample from a dog, a careful morphological and morphometric analysis of individual parasite elements is mandatory. Key diagnostic features (i.e., size, wall surface pattern and aspects of plugs) should be carefully examined when eggs with overlapping shape and appearance are detected. In conclusion, given the importance in clinical practice of canine trichuroids and the zoonotic potential of C. aerophila, these nematodes should be included into the differential diagnosis of intestinal and respiratory parasitoses of dogs by a thorough microscopic analysis of all trichuroid ova present in microscopic fields.
Transhepatic percutaneous endoscopic gastrostomy  [PDF]
Guido Poggi, Benedetta Montagna, Pamela Di Cesare
Open Journal of Gastroenterology (OJGas) , 2013, DOI: 10.4236/ojgas.2013.32014
Abstract:

We describe the case of a hepatic injury after the insertion of a PEG. In a cirrhotic woman affected by a locally advanced cancer of the pharynx, the PEG tube was inserted through the edge of the left lobe of the liver. The patient was treated with a conservative approach by managing abdominal pain and the PEG was removed after 4 months without complication. Hepatic injury is a rare complication of PEG placement; in order to avoid it, PEG tube should be inserted to the left of the abdominal midline and the lower edge of the liver should be defined by palpation; in cirrhotic patients, where left hepatic lobe hyper-trophy is common, ultrasound guidance could have been appropriate.

How fertility and union stability interact in shaping new family patterns in Italy and Spain
Lucia Coppola,Mariachiara Di Cesare
Demographic Research , 2008,
Abstract: In this paper we investigate the interrelationships between fertility decisions and union dissolution in Italy and Spain. We argue that there might exist a spurious relationship between these two life trajectories. The analysis is based on the 1996 Fertility and Family Survey data for Italy and Spain. Results show that there is a spurious relationship between fertility and union dissolution in Italy but not in Spain. Nevertheless, in both countries, there is an evident direct effect of each process on the other: union dissolution decreases the risk of further childbearing, while childbirths decrease the risk of union dissolution.
The Mathematics of the Relationship between the Default Risk and Yield-to-Maturity of Coupon Bonds
Sara Cecchetti,Antonio Di Cesare
Quantitative Finance , 2012,
Abstract: The paper analyzes the mathematics of the relationship between the default risk and yield-to-maturity of a coupon bond. It is shown that the yield-to-maturity is driven not only by the default probability and recovery rate of the bond but also by other contractual characteristics of the bond that are not commonly associated with default risk, such as the maturity and coupon rate of the bond. In particular, for given default probability and recovery rate, both the level and slope of the yield-to-maturity term structure depend on the coupon rate, as the higher the coupon rate the higher the yield-to-maturity term structure. In addition, the yield-to-maturity term structure is upward or downward sloping depending on whether the coupon rate is high or low enough. Similar qualitative results also holds for CDS spreads. Consequently, the yield-to-maturity is an indicator that must be used cautiously as a proxy for default risk.
Análisis micro de los determinantes de la fecundidad adolescente en Brasil y Colombia
Mariachiara di Cesare,Jorge Rodríguez Vignoli
Papeles de población , 2006,
Abstract: En el presente estudio se utilizaron los datos de las DHS de Brasil (1996) y Colombia (2000) y se han aplicado modelos de regresión logística para determinar cuáles son los factores de riesgo de la fecundidad adolescente. Los resultados evidencian la mayor vulnerabilidad de los grupos socioeconomicamente más débiles, y la interacción entre variables intermedias y variables socioeconómicas. Sin embargo, la educación pierde su efecto específico al controlar el estrato socioeconómico; y el lugar de residencia parece no afectar la probabilidad de ser madre adolescente. Esto sugiere que la fecundidad temprana en ambos países no se puede definir como un comportamiento tradicional, sino más bien como un comportamiento conectado con el proceso de secularización valórica.
