Dolphin Morbillivirus Associated with a Mass Stranding of Sperm Whales, Italy
In September 2014, 7 sperm whales stranded along the Adriatic Italian coastlines. Postmortem investigations on 3 dead females dead and in 1 fetus harbored by the largest one revealed molecular and immunoistochemical evidences of dolphin morbillivirus infection. A possible role of the virus in the stranding event was considered
Experimental determination of the particle dynamics into a rotating tube
This paper reports the procedure for analysing the biomass powder bed characteristics realized in an experimental pyrolysis reactor. The reaction apparatus is made of a quartz tube which can rotate, horizontally or slightly inclined, with different speeds. Depending on the tube inclination and rotation, different motion conditions (regime, hold-up, residence time and advancing rate) are possible; also the particle characteristics (nature, shape and size, humidity) and the flow rate affect the bed behaviour. After taking some pictures of the bed from the discharge side, they can be analysed by means of the geometry rules; this procedure is here described. In this way the bed profile can be obtained, and this information can be used to calculate the parameters of a proper model, already developed. The methodology here presented will be used in the future to find data to be used in the development of a whole pyrolysis process model including also heat exchange, gas fluid dynamics and pyrolysis reaction kinetics
The relationship between health care users’ demand and the health care system’s response: a research on change observed in the health care system, in the hospital and in the territory
The present research study aims at exploring the representation of the health service within a group of hospital physicians and nurses. The objective is to identify how the symbolic dynamic of hospital workers shapes their own praxis. The texts of interviews with 25 hospital workers have been subjected to Emotional Text Analysis (ETA). Five clusters emerge from the analysis where the topic of giving life and avoiding death is central and where the hospital assumes a thaumaturgical and basically omnipotent role. This is in conflict with recognizing the limitations of therapy. Only in the background the culture of curing the patients appears, characterized by aggressive reactivity towards the crisis which leads patients to emergency intervention because crises are ascribed to deviances frommedical prescription. Emergency intervention is ultimately the kind of intervention which the hospital believes it is capable to provide. Another problem is the lack of filters provided by bureaucratized general practitioners, whose cooperation would be essential, but who are supposed to have no longer the necessary relationship with their patients
I Lepidotteri della "Palude del Busatello" (Verona, Mantova)
Con il presente lavoro vengono riportati i risultati di 5 anni di ricerche (2011-2015) sui Lepidotteri della zona umida "Palude del Busatello" (comuni di Gazzo Veronese ed Ostiglia, province di Verona e Mantova). Complessivamente, sommando i dati storici di una precedente campagna (1981-1983), sono state censite 429 specie delle quali 2 nuove per la fauna italiana: Acleris lorquiniana (Duponchel, 1835) e Rhyparioides metelkana (Lederer, 1861). Altre due specie, Monochroa suffusella (Douglas, 1850) e M. divisella (Douglas, 1850) sono state solo recentemente segnalate come nuove per l'Italia in alcune aree umide del Friuli Venezia Giulia. Tutte le specie sono elencate in una tabella e per ognuna vengono riportati distribuzione, corologia, regime alimentare, fenologia, modalità di raccolta ed ecotipo. Le specie strettamente legate all'ambiente palustre sono state commentate, assieme alle più caratteristiche dell'area circumpalustre. L'importanza dell'area è sottolineata dalla presenza di Lycaena dispar (Haworth, 1803), una specie protetta inclusa nella Direttiva Comunitaria Habitat (Dir. 92/43 CEE). Una comparazione con il precedente studio ha evidenziato un aumento del numero di specie caratteristiche della fascia arborea (dal 22 al 40%), dovuto principalmente alla riforestazione effettuata in alcuni settori del biotopo. Ulteriori comparazioni sono state effettuate con alcuni biotopi umidi friulani recentemente censiti e studiati. Sono inoltre discussi in dettaglio gli aspetti gestionali dell'area
High prevalence of hepatitis C virus infection in patients with B-cell lymphoproliferative disorders in Italy.
Starting from the observation that a number of consecutive patients with non-Hodgkin's lymphoma (NHL) resulted positive for hepatitis C virus (HCV) antibodies on routine testing, we set up a survey for HCV contact prevalence in all patients with lymphoproliferative disorders (LPD) followed in our institution. We searched for HCV antibodies by a thirdgeneration ELISA technique, followed by a confirmation test (RIBA III); serum viral RNA and HCV genotype were investigated by a RT-PCR technique. We screened a total of 315 patients suffering from B-NHL (91), multiple myeloma (56), MGUS (48), chronic lymphocytic leukemia (57), Waldentrom's macroglobulinemia (13), Hodgkin's disease (HD)(43), and T-NHL (9). While only I of 52 patients with a non-B-LPD (HD or T-NHL) had signs of HCV contact (i.e., 1.9%, which is in the range of the normal population in the South of Italy), 59 of 263 patients with a B-LPD (22.4%) had HCV antibodies or RNA, or both, with no major differences among the various types of disorders, except for WM, in which the rate was higher (61.5%). The same prevalence was found for patients tested at diagnosis or during the follow-up, and in transfused or never-transfused patients. Only a few patients were aware of having a liver disease; one-half of HCV-positive patients never had transaminase increase. A review of data from Central and Northern Italy is included, showing similar findings; a report from Japan has confirmed such an association, while limited surveys in England have not revealed any correlation. These findings may have important biological and clinical implications
"Delirium Day": a nationwide point prevalence study of delirium in older hospitalized patients using an easy standardized diagnostic tool
To date, delirium prevalence in adult acute hospital populations has been estimated generally from pooled findings of single-center studies and/or among specific patient populations. Furthermore, the number of participants in these studies has not exceeded a few hundred. To overcome these limitations, we have determined, in a multicenter study, the prevalence of delirium over a single day among a large population of patients admitted to acute and rehabilitation hospital wards in Italy
Activation of mammalian target of rapamycin (mTOR) in triple negative feline mammary carcinomas
BACKGROUND: Triple negative breast cancer (TNBC) in humans is defined by the absence of oestrogen receptor (ER), progesterone receptor (PR) and HER2 overexpression. Mammalian target of rapamycin (mTOR) is overexpressed in TNBC and it represents a potential target for the treatment of this aggressive tumour. Feline mammary carcinoma (FMC) is considered to be a model for hormone-independent human breast cancer. This study investigated mTOR and p-mTOR expression in FMC in relation to triple negative (TN) phenotype. RESULTS: The expression of mTOR, p-mTOR, ERα, PR and HER2 was evaluated in 58 FMCs by immunohistochemistry and in six FMC cell lines by Western blot analysis. 53.5% of FMC analyzed were ER, PR, HER2 negative (TN-FMC) while 56.9% and 55.2% of cases expressed mTOR and p-mTOR respectively. In this study we found that m-TOR and p-mTOR were more frequently detected in TN-FMC and in HER2 negative samples. CONCLUSIONS: In this study, we demonstrate that there is also a FMC subset defined as TN FMC, which is characterised by a statistically significant association with m-TOR and p-mTOR expression as demonstrated in human breast cancer
"Delirium Day": A nationwide point prevalence study of delirium in older hospitalized patients using an easy standardized diagnostic tool
Background: To date, delirium prevalence in adult acute hospital populations has been estimated generally from pooled findings of single-center studies and/or among specific patient populations. Furthermore, the number of participants in these studies has not exceeded a few hundred. To overcome these limitations, we have determined, in a multicenter study, the prevalence of delirium over a single day among a large population of patients admitted to acute and rehabilitation hospital wards in Italy. Methods: This is a point prevalence study (called "Delirium Day") including 1867 older patients (aged 65 years or more) across 108 acute and 12 rehabilitation wards in Italian hospitals. Delirium was assessed on the same day in all patients using the 4AT, a validated and briefly administered tool which does not require training. We also collected data regarding motoric subtypes of delirium, functional and nutritional status, dementia, comorbidity, medications, feeding tubes, peripheral venous and urinary catheters, and physical restraints. Results: The mean sample age was 82.0 ± 7.5 years (58 % female). Overall, 429 patients (22.9 %) had delirium. Hypoactive was the commonest subtype (132/344 patients, 38.5 %), followed by mixed, hyperactive, and nonmotoric delirium. The prevalence was highest in Neurology (28.5 %) and Geriatrics (24.7 %), lowest in Rehabilitation (14.0 %), and intermediate in Orthopedic (20.6 %) and Internal Medicine wards (21.4 %). In a multivariable logistic regression, age (odds ratio [OR] 1.03, 95 % confidence interval [CI] 1.01-1.05), Activities of Daily Living dependence (OR 1.19, 95 % CI 1.12-1.27), dementia (OR 3.25, 95 % CI 2.41-4.38), malnutrition (OR 2.01, 95 % CI 1.29-3.14), and use of antipsychotics (OR 2.03, 95 % CI 1.45-2.82), feeding tubes (OR 2.51, 95 % CI 1.11-5.66), peripheral venous catheters (OR 1.41, 95 % CI 1.06-1.87), urinary catheters (OR 1.73, 95 % CI 1.30-2.29), and physical restraints (OR 1.84, 95 % CI 1.40-2.40) were associated with delirium. Admission to Neurology wards was also associated with delirium (OR 2.00, 95 % CI 1.29-3.14), while admission to other settings was not. Conclusions: Delirium occurred in more than one out of five patients in acute and rehabilitation hospital wards. Prevalence was highest in Neurology and lowest in Rehabilitation divisions. The "Delirium Day" project might become a useful method to assess delirium across hospital settings and a benchmarking platform for future surveys
Prescription appropriateness of anti-diabetes drugs in elderly patients hospitalized in a clinical setting: evidence from the REPOSI Register
Diabetes is an increasing global health burden with the highest prevalence (24.0%) observed in elderly people. Older diabetic adults have a greater risk of hospitalization and several geriatric syndromes than older nondiabetic adults. For these conditions, special care is required in prescribing therapies including anti- diabetes drugs. Aim of this study was to evaluate the appropriateness and the adherence to safety recommendations in the prescriptions of glucose-lowering drugs in hospitalized elderly patients with diabetes. Data for this cross-sectional study were obtained from the REgistro POliterapie-Società Italiana Medicina Interna (REPOSI) that collected clinical information on patients aged ≥ 65 years acutely admitted to Italian internal medicine and geriatric non-intensive care units (ICU) from 2010 up to 2019. Prescription appropriateness was assessed according to the 2019 AGS Beers Criteria and anti-diabetes drug data sheets.Among 5349 patients, 1624 (30.3%) had diagnosis of type 2 diabetes. At admission, 37.7% of diabetic patients received treatment with metformin, 37.3% insulin therapy, 16.4% sulfonylureas, and 11.4% glinides. Surprisingly, only 3.1% of diabetic patients were treated with new classes of anti- diabetes drugs. According to prescription criteria, at admission 15.4% of patients treated with metformin and 2.6% with sulfonylureas received inappropriately these treatments. At discharge, the inappropriateness of metformin therapy decreased (10.2%, P < 0.0001). According to Beers criteria, the inappropriate prescriptions of sulfonylureas raised to 29% both at admission and at discharge. This study shows a poor adherence to current guidelines on diabetes management in hospitalized elderly people with a high prevalence of inappropriate use of sulfonylureas according to the Beers criteria
