Ecology of Alopoglossus angulatus and A. atriventris (Squamata, Gymnophthalmidae) in western Amazonia
We studied the ecology of Alopoglossus angulatus and A. atriventris in western Amazonia. Both species are found in leaf litter of lowland tropical forest, but A. angulatus tends to be found near water whereas A. atriventris is found in terra firme forest. Both tend to be active in shade on sunny and cloudy days. Body size of adults differs (A. angulatus larger), but species differences in sizeadjusted morphology are minor. Sexual dimorphism exists in relative head length (males larger) only in A. atriventris. Diets are similar, with roaches, spiders, grasshoppers/crickets, and springtails dominating the diet. Overall, these lizards are similar ecologically even though they occur together at many sites. Leaf litter and shaded forest appear to be requisites for survival at the local level
An unusual cause of eosinophilic pleural effusion and migrating biliary stenosis: Strongyloides stercoralis infection in a young immunocompetent man
We present the case of a 33 year-old Italian man who came to our attention for epigastralgia associated with polyserositis (pleural and pericardial and peritoneal effusion with the involvement of the Douglas excavation), in the absence of a significant medical history. Laboratory analysis revealed exudative eosinophilic pleural effusion; serial imaging techniques showed a transient stenosis of the right hepatic duct and a subsequent stenosis of the left hepatic duct. After several negative sierological investigations, a positive antistrongyloides IgG antibodies titre rose suspicions of Strongyloides infection, which was confirmed by positive stool sample for parasite. Ivermectin-therapy was started and the patient’s fully recovered
Weekend-Based Parent-Group Intervention to Reduce Stress in Parents of Children and Adolescents with Type 1 Diabetes: A Pilot Study
Diagnosis of type 1 diabetes (T1D) in a child is often associated with anger, denial, fear, and depression from the parents. The aim of the study was to improve parents' adaptation to the diagnosis of diabetes of their child. Sixty-two parents (29 mothers, 33 fathers) of 36 children with type 1 diabetes (mean age=11.3-3.3 years; diabetes duration>1 year; HbA1c=57 +/- 11 mmol/mol) participated in a three-day educational working group pilot intervention study. Intervention was based on the reexamination of the traumatic event of diagnosis of T1D through spatial and time-line anchorage, retracing of the future, emotional awareness, and interactive discussion. Relaxing technique, diaphragmatic breathing, and guided visualization were used by 2 psychologists and 1 pediatric endocrinologist. The study was approved by EC and participants filled a consent form. At baseline and after intervention, parents filled in a questionnaire including Diabetes-Related Distress (DRD), Parent Health Locus of Control Scale (PHLOC), Parent Stress Index Short Form (PSI-SF), Hypoglycemia Fear Survey-Parents (HFS-P) and Hypoglycemia Fear Survey-Parents of Young Children (HFS-P-YC), and Health Survey Short Form-36 (SF-36). Three months after the intervention, both parents reported a reduction in the "difficult child" subscale of the PSI-SF (p<0.05) and increased scores of social functioning of the SF-36 (p<0.05). DRD score was significantly reduced in mothers (p=0.03), while the "parental distress" subscale of the PSI-SF was significantly improved in fathers (p=0.03). This weekend-based parent group intervention seems to reduce stress and improve social functioning of parents of children and adolescents with type 1 diabetes

Loss of the Actin Remodeler Eps8 Causes Intestinal Defects and Improved Metabolic Status in Mice
In a variety of organisms, including mammals, caloric restriction improves metabolic status and lowers the incidence of chronic-degenerative diseases, ultimately leading to increased lifespan. Here we show that knockout mice for Eps8, a regulator of actin dynamics, display reduced body weight, partial resistance to age- or diet-induced obesity, and overall improved metabolic status. Alteration in the liver gene expression profile, in behavior and metabolism point to a calorie restriction-like phenotype in Eps8 knockout mice. Additionally, and consistent with a calorie restricted metabolism, Eps8 knockout mice show increased lifespan. The metabolic alterations in Eps8 knockout mice correlated with a significant reduction in intestinal fat absorption presumably caused by a 25% reduction in intestinal microvilli length. Our findings implicate actin dynamics as a novel variable in the determination of longevity. Additionally, our observations suggest that subtle differences in energy balance can, over time, significantly affect bodyweight and metabolic status in mice
Lifestyles and socio-cultural factors among children aged 6-8 years from five Italian towns: The MAPEC-LIFE study cohort
Background: Lifestyles profoundly determine the quality of an individual’s health and life since his childhood.
Many diseases in adulthood are avoidable if health-risk behaviors are identified and improved at an early stage of
life. The aim of the present research was to characterize a cohort of children aged 6–8 years selected in order to
perform an epidemiological molecular study (the MAPEC_LIFE study), investigate lifestyles of the children that
could have effect on their health status, and assess possible association between lifestyles and socio-cultural factors.
Methods: A questionnaire composed of 148 questions was administered in two different seasons to parents of
children attending 18 primary schools in five Italian cities (Torino, Brescia, Pisa, Perugia and Lecce) to obtain
information regarding the criteria for exclusion from the study, demographic, anthropometric and health
information on the children, as well as some aspects on their lifestyles and parental characteristics. The results
were analyzed in order to assess the frequency of specific conditions among the different seasons and cities and
the association between lifestyles and socio-economic factors.
Results: The final cohort was composed of 1,164 children (50.9 boys, 95.4% born in Italy). Frequency of some
factors appeared different in terms of the survey season (physical activity in the open air, the ways of cooking
certain foods) and among the various cities (parents’ level of education and rate of employment, sport, traffic
near the home, type of heating, exposure to passive smoking, ways of cooking certain foods). Exposure to
passive smoking and cooking fumes, obesity, residence in areas with heavy traffic, frequency of outdoor play and
consumption of barbecued and fried foods were higher among children living in families with low educational
and/or occupational level while children doing sports and consuming toasted bread were more frequent in families
with high socio-economic level.
Conclusions: The socio-economic level seems to affect the lifestyles of children enrolled in the study including
those that could cause health effects. Many factors are linked to the geographical area and may depend on
environmental, cultural and social aspects of the city of residence
Ecosistemi per la ricerca Atti Convegno ACNP/NILDE Trieste, 22-23 maggio 2014
Il secondo convegno congiunto ACNP / NILDE: ecosistemi per la ricerca è stato
ospitato dal 22 al 23 maggio 2014 dall’Università di Trieste.
Sotto gli auspici della stessa Università di Trieste e degli altri enti di ricerca
del Friuli Venezia Giulia1 sono stati affrontati in un’ottica internazionale i temi
del rapporto tra cataloghi collettivi e servizi interbibliotecari, e il più generale
ambito dei servizi bibliografici per la ricerca scientifica.
ACNP e NILDE possono essere considerati un vero e proprio ecosistema. Le
biblioteche e i bibliotecari collaborano tra di loro in maniera reciproca e secondo
modalità interconnesse, offrendo agli utenti servizi sempre più evoluti e dinamici.
Questo ecosistema, essendo aperto, mette i propri servizi a disposizione della
ricerca scientifica in senso generale. Il convegno di Trieste ha offerto l’occasione
di investigare e proporre soluzioni innovative, interconnessioni e relazioni nuove
e più proficue.
Il convegno ha presentato alcune rilevanti esperienze internazionali in tema
di servizi interbibliotecari e cataloghi collettivi e la prosecuzione di attività che erano state proposte come spunti di ispirazione nel convegno precedente2 inoltre
si sono condotte delle riflessioni sulle nuove esigenze dell’utenza.
Una ultima parte è dedicata alla illustrazione degli sviluppi tecnici e le prospettive
future di ACNP e di NILDE.
Hanno partecipato all’evento oltre 200 colleghi italiani e stranieri ed i relatori
dei 18 contributi provenivano da Italia, Germania, Austria, Grecia, Slovenia e
Stati Uniti. Il carattere di confronto e di condivisione delle esperienze tipico della
realtà partecipativa di ACNP e NILDE, è emerso anche in questa occasione nella
tavola rotonda - di cui viene riportato un resoconto dettagliato - che ha affrontato
il tema della valutazione della ricerca dal punto di vista delle biblioteche. Inoltre,
la molto partecipata sessione poster ha ospitato 13 lavori- anch’essi riportati nel
volume - incentrati oltre che su ACNP e NILDE anche sul tema ricerca e sistema
biblioteca, dando ottimi spunti di partecipazione, dialogo e confronto sulle diverse
realtà in cui operiamo
Antimicrobial resistance among migrants in Europe: a systematic review and meta-analysis
BACKGROUND: Rates of antimicrobial resistance (AMR) are rising globally and there is concern that increased migration is contributing to the burden of antibiotic resistance in Europe. However, the effect of migration on the burden of AMR in Europe has not yet been comprehensively examined. Therefore, we did a systematic review and meta-analysis to identify and synthesise data for AMR carriage or infection in migrants to Europe to examine differences in patterns of AMR across migrant groups and in different settings. METHODS: For this systematic review and meta-analysis, we searched MEDLINE, Embase, PubMed, and Scopus with no language restrictions from Jan 1, 2000, to Jan 18, 2017, for primary data from observational studies reporting antibacterial resistance in common bacterial pathogens among migrants to 21 European Union-15 and European Economic Area countries. To be eligible for inclusion, studies had to report data on carriage or infection with laboratory-confirmed antibiotic-resistant organisms in migrant populations. We extracted data from eligible studies and assessed quality using piloted, standardised forms. We did not examine drug resistance in tuberculosis and excluded articles solely reporting on this parameter. We also excluded articles in which migrant status was determined by ethnicity, country of birth of participants' parents, or was not defined, and articles in which data were not disaggregated by migrant status. Outcomes were carriage of or infection with antibiotic-resistant organisms. We used random-effects models to calculate the pooled prevalence of each outcome. The study protocol is registered with PROSPERO, number CRD42016043681. FINDINGS: We identified 2274 articles, of which 23 observational studies reporting on antibiotic resistance in 2319 migrants were included. The pooled prevalence of any AMR carriage or AMR infection in migrants was 25·4% (95% CI 19·1-31·8; I2 =98%), including meticillin-resistant Staphylococcus aureus (7·8%, 4·8-10·7; I2 =92%) and antibiotic-resistant Gram-negative bacteria (27·2%, 17·6-36·8; I2 =94%). The pooled prevalence of any AMR carriage or infection was higher in refugees and asylum seekers (33·0%, 18·3-47·6; I2 =98%) than in other migrant groups (6·6%, 1·8-11·3; I2 =92%). The pooled prevalence of antibiotic-resistant organisms was slightly higher in high-migrant community settings (33·1%, 11·1-55·1; I2 =96%) than in migrants in hospitals (24·3%, 16·1-32·6; I2 =98%). We did not find evidence of high rates of transmission of AMR from migrant to host populations. INTERPRETATION: Migrants are exposed to conditions favouring the emergence of drug resistance during transit and in host countries in Europe. Increased antibiotic resistance among refugees and asylum seekers and in high-migrant community settings (such as refugee camps and detention facilities) highlights the need for improved living conditions, access to health care, and initiatives to facilitate detection of and appropriate high-quality treatment for antibiotic-resistant infections during transit and in host countries. Protocols for the prevention and control of infection and for antibiotic surveillance need to be integrated in all aspects of health care, which should be accessible for all migrant groups, and should target determinants of AMR before, during, and after migration.
