We carried out the first survey of Hymenolepis spp. infection in pet rodents in Italy. Fresh fecal samples were collected from 172 pet rodents as follows: guinea pigs ( Cavia porcellus; n = 60), squirrels ( Callosciurus finlaysonii, Callosciurus prevosti, Tamias striatus, Tamias sibiricus, Sciurus calorinensis; n = 52), hamsters ( Phodopus campbelli, Mesocricetus auratus; n = 30), chinchillas ( Chinchilla lanigera; n = 13), rats ( Rattus norvegicus; n = 10), and mice ( Mus minutoides; n = 7). These animals were housed either in pet shops or in private houses. All fecal samples were processed using the FLOTAC pellet technique to assess the number of eggs per gram (EPG) of feces. Eggs of Hymenolepis nana were found in 24 out of 172 (13.9 %; 95 % confidence interval = 9.3-20.2 %) pet rodents. Of those rodents, 41.6 % (10/24) were rats (mean EPG = 55.7; range = 2-200), 29.2 % (7/24) mice (mean EPG = 64.5; range = 32-120), 25.0 % (6/24) were chinchillas (mean EPG = 25.5; range = 10-50), and 4.2 % (1/24) hamsters ( P. campbelli) (EPG = 86.0). In addition, Hymenolepis diminuta eggs were found in 2 out of 172 (1.2 %; 95 % confidence interval = 0.2-4.6 %) rodents examined, both of which (100 %; 2/2) were pet squirrels ( C. prevosti) (mean EPG = 10; range = 4-16). To the authors' knowledge, this is the first report of a natural infection of H. diminuta in pet squirrels. [ABSTRACT FROM AUTHOR]

This work shows an electronic management system equipped with two microcontrollers for ethanol injection in the air intake pipe of a diesel engine. The aim was to reduce the NOx emissions, while increasing the amount of renewable fuel in the mixture. The system was specially developed to detect the high-pressure pulse in the diesel injection line and to trigger the ethanol injection. An intrusive pressure sensor was installed in the diesel injection pipe to allow the measurement. Through a security protocol, the timing and duration of injection can be adjusted. The system evaluates the temperature reduction caused by the ethanol injection using two NTC thermal sensors. The exhaust gas temperature was determined by a type K thermocouple. The system was tested in a single cylinder diesel generator with mechanical injection at 1,750, 1,800, and 1,850 rpm in order to verify the injection frequency, the injection delays, the NOx emissions and the intake air, and exhaust gas temperature variation. It was found that the injection delays were less than 850 $$\mu $$ s. A reduction in the intake air and exhaust gas temperatures was observed as the ethanol content increased. Injections of 15 v/v% ethanol into the intake air pipe have shown a considerable reduction (60 %) in NOx emissions when compared to diesel-biodiesel blend composed of 70 v/v% mineral diesel and 30 v/v% soybean biodiesel. It was demonstrated that the addition of ethanol can be an important method to reduce the amount of NOx in the exhaust gas of Diesel engines. [ABSTRACT FROM AUTHOR]

9. The Role of Gasping in Resuscitation.

Roppolo, L. P., Pepe, P. E., and Bobrow, B. J.
- Abstract
Gasping is a physiologic entity that, among other conditions, is seen typically in mammals who have sustained a global ischemic insult such as sudden cardiac arrest or severe hemorrhagic shock [1–13]. Scientists have defined a gasp formally in nomenclature consensus processes as ˵an abrupt, sudden, transient inspiratory effort″ [13] and it has been described in the published literature since 1812 [11]. The classic gasping that occurs after sudden cardiac arrest is also sometimes referred to as ˵agonal breaths″ or ˵agonal respirations″ [1, 3–6, 9]. However, the term agonal breathing may also be used by some when referring to a broader variety of respiratory efforts or conditions [12, 14]. Agonal breathing may, therefore, refer to various kinds of abnormal breathing observed at the time of clinical death, during certain types of stroke, or in progressive respiratory failure when rapid breathing reverts to slower and often shallow breaths [6, 11, 12, 14]. Classic gasps, according to strict definition, however, are usually sudden, abrupt, and much brisker and larger than normal respiratory efforts [13]. [ABSTRACT FROM AUTHOR]

- Abstract
The dependence of planetary statistics on the physical conditions during the initial stages of the system (i.e. in the proto-planetary disk) represent an essential constraint on planetary formation mechanisms. The planets orbiting M dwarfs were formed in a lower-mass disk, with an ice boundary much closer to the star, and a longer orbital period (for the same separation) than the planets formed around solar-type stars. Planetary formation is extremely sensitive to all three parameters, and the relative statistical properties of planets around G dwarfs and very low mass stars therefore represent a very sensitive diagnostic. In this talk we will present the first results of a very sensitive search for planets around southern M dwarfs with the HARPS spectrograph (as part of the HARPS GTO program). The northern counterpart of the survey will be conducted with SOPHIE at OHP, within the SOPHIE Exoplanets Consortium. These first results suggest that that planets around M dwarfs have lower mass than around solar type stars. [ABSTRACT FROM AUTHOR]

Leibundgut, Bruno, Santos, Nuno C., Pasquini, Luca, Correia, Alexandre C. M., Romaniello, Martino, Lovis, C., Mayor, M., Pepe, F., Queloz, D., and Udry, S.
- Abstract
We present results from the first three years of operations of the HARPS spectrograph installed on the ESO-3.6m telescope at La Silla Observatory, Chile. This instrument, primarily built to detect extrasolar planetary systems, has demonstrated a long-term accuracy below the 1 m s-1, level, exploring a new regime in RV precision and discovering several very low-mass planets. We present recent improvements in the wavelength calibration process, including the creation of a new ThAr reference atlas and the use of a much larger number of lines to fit the wavelength solution. Other instrumental error sources such as guiding accuracy and photon noise are discussed and a global error budget is presented. Finally, ongoing studies to obtain an "ideal" wavelength calibration are briefly reviewed. [ABSTRACT FROM AUTHOR]

- Abstract
Most catastrophic mudslides in Campania are related to soils developing upon pyroclastic materials covering carbonatic relieves of the Campanian Apennines. The soil observed in the detachment crowns of the investigated fast mudflow consisted of fertile Andosols (generally Hapludands and Udivitrands) that were very sensitive to anthropic or natural changes. This is due to the unique chemical, physical, morphological and hydrological behaviour of these soils, including (i) high water retention near saturation, (ii) high hydraulic conductivity, (iii) high smeariness of most horizons, and (iv) high vertical and lateral variability of the properties of the soil horizons. Aspect is important in determining soil susceptibility to landslide triggering and landslide susceptibility is related to hydrological properties that induce higher water storage especially in northern aspect soils. It is clear that stability of these soils requires conservation, implemented through appropriate forest planning and management. Improved risk management policies are necessary to preserve soil continuity and to decrease the risk both of surface soil erosion and to human lives and infrastructure. [ABSTRACT FROM AUTHOR]

- Abstract
We present an overview of the Differential SAR Interferometry algorithm referred to as Small BAseline Subset (SBAS) technique, that allows us to detect surface deformation and to analyze their space-time characteristics. Following the description of the main theoretical aspects of the algorithm, we present several results obtained by applying the SBAS approach in selected case studies relevant to phenomena affecting volcanic areas (Campi Flegrei caldera and Somma-Vesuvio complex, Italy), aquifers (Santa Clara area within the San Francisco bay, California) and landslides (Maratea Valley, Italy). The overall analysis is carried out by using multilook DInSAR interferograms with a spatial resolution of the order of 100 × 100 m, computed from SAR data acquired by the ERS-1 and ERS-2 sensors. In particular, we highlight the peculiarities of the SBAS technique and its surface deformation retrieval capability for what concerns both large-scale deformation phenomena and more localized displacement effects.

Walker, John M., Ambrosius, Walter T., Alonzo, Todd A., and Pepe, Margaret Sullivan
- Abstract
Diagnostic tests, medical tests, screening tests, biomarkers, and prediction rules are all types of classifiers. This chapter introduces methods for classifier development and evaluation. We first introduce measures of classification performance including sensitivity, specificity, and receiver operating characteristic (ROC) curves. We then review some issues in the design of studies to assess and compare the performance of classifiers. Approaches for using the data to estimate and compare classifier accuracy are then introduced. Next, methods for combining multiple classifiers into a single classifier are presented. Lastly, we discuss other important aspects of classifier development and evaluation. The methods presented are illustrated with real data. [ABSTRACT FROM AUTHOR]

- Abstract
There are obvious anatomical, physical, and genetic differences between men and women that have always been a central focus of human life. Such differences have become the target of humor, politics, and legal issues and many other aspects of the human experience. At the same time, though receiving less notoriety, there are also striking sex-related differences in the presentation, outcomes, and responses to many disease processes and therapies.

- Abstract
Disasters, particularly earthquakes, volcanoes, floods, war-related complications, famine and infectious epidemics, have been a part of recorded human experience. From Pompeii to the Johnston Flood and World War II and the Black Plague to the Spanish Influenza, there have been catastrophic occurrences that will not long be forgotten by either legend or history books. Nevertheless, those occurrences were relatively few and far-between before the mid-twentieth century. Indeed, the nature of disasters has changed since then. From terrorists taking advantage of ‘new technology' to weather-related events that cause trillions of dollars worth of damages and economic loss, the world has evolved. [ABSTRACT FROM AUTHOR]

- Abstract
A patient with out-of-hospital cardiac arrest (CA) stands little chance for survival without prior organization and preparations for immediate resuscitation. Fortunately, many communities have achieved relative success with resuscitation since the 1970s. In the 1970s, cities such as Seattle and Milwaukee achieved overall survival-to-hospital discharge rates for the subgroup of patients with out-of-hospital ventricular fibrillation (VF) that exceeded 20 to 30% (1,2). Both of these communities used a classic deployment system for out-of-hospital CA that sent a three- to four-member firefighter crew as a neighborhood "first-responder" (FR) followed by a two- (or more) member paramedic ambulance crew. In cases of witnessed collapse in which the patient received immediate basic cardiopulmonary resuscitation (BCPR) by bystanders and presented to paramedics with VF, survival rates in these systems exceeded 40%. This finding was duplicated in several other communities, including the City of Houston Emergency Medical Services (EMS) system after a major restructuring in the 1980s (3). [ABSTRACT FROM AUTHOR]

Objective:The objective of this work is to evaluate the association between Selenium (Se)-, Copper (Cu)- and Zinc (Zn)-circulating concentrations and indicators of nutritional status.Subjects/Methods:This study enroled 428 institutionalised elderly. The diagnostic tools used are a form to collect data regarding gender, age, duration of stay in nursing home, number of prescribed drugs, chronic diseases, Mini Nutritional Assessment (MNA), anthropometric measurements, albumin, transferrin and serum concentrations of Se, Cu and Zn. The collected data were analysed with descriptive assessments of the differences χ
2 , Student's t-test and analysis of variance. Multivariate linear regression were performed to evaluate the association between the concentrations of each trace elements and the other variables.Results:The study population was represented by 327 women and 101 men, of whom 13.8% were 65-75 years old and 47.4% were older than 85 years. According to the MNA score, 58.4% were at risk of malnutrition and 21.3% were malnourished. The results show a significant reduction in the average concentrations of Se and Zn in women when the nutritional status gets worse. The same trend, although not statistically significant, is also observed in men. In both genders, the Cu concentration does not show a statistically significant association with nutritional status. Multivariate linear regression show some positive or negative associations.Conclusions:Our study seems to confirm the association between Se and nutritional status, as well as with some blood chemistry parameters. The length of institutionalisation seems to be an independent predictor of Se concentration. [ABSTRACT FROM AUTHOR]- Published

- Abstract
The early diagenesis of the superficial sediment of the Lac du Bouchet has been studied by analysis of interstitial water and solid phase. 14C dating of the sediment gives 2500±350 years at a depth of 80 cm below the sediment-water Interface (SWI). Solid phase is made of 19 to 49% clays (Mainly kaolinite), detrital minerals (quartz, feldspars, ferromagnesian), Diatoms frustules and organic matter (ligno-cellulosic debris, pollens, amorphous grey matter). The main part of organic matter (OM) mineralisation takes place in the first 10 to 20 centimetres under the SWI, but continues at a deeper level 3 to 4 times more slowly. Methanogenesis reaction is the dominant degradation process (90 to 93% in the upper section of the mud, up to 97% below), followed by sulphate reduction (4% in spring and 7% in autumn, only in the top section) and iron reduction (3 to 2%). A formula is proposed for OM undergoing oxidation: (CH2O)106(NH3)13.6(H3PO4)0.84. [ABSTRACT FROM AUTHOR]

To evaluate prostate cancer (PCa) detection and incidence of pathologically insignificant PCa (pIPCa) tumour using percent-free PSA (%f-PSA) in patients with total PSA 10 ng ml−1. From February 2002 to October 2009, 14 453 patients (median 60.5 years) were enrolled in a case-finding protocol for the early diagnosis of PCa. Indications to biopsy were suspicious digital rectal examination; PSA >10 ng ml−1; PSA2.5 ng ml−1, included between 2.6-4 and 4.1-10 ng ml−1 with %f-PSA <15, <20 and <25%, respectively. A median of 18 and 26 cores in case of primary and repeated biopsy were determined; 2123 men underwent prostate biopsy, of whom 1589 (74.8%) had a PSA 10 ng ml−1. A PCa was found in 777 (36.6%) and in 35 (23.3%) patients at primary and repeated biopsy: 459 and 26 men had PSA 10 ng ml−1 and 419 and 26 patients underwent surgery, respectively, 244 (58.3%) and 18 (69.2%) had an organ-confined PCa with a pIPCa incidence equal to 1.4 and 7.7%, respectively. Cancer detection rate of 28.8% in patients with PSA 10 ng ml−1 associated with a low incidence of pIPCa should induce to introduce %f-PSA in screening programmes to reduce the risk of overdiagnosis.

- Abstract
BACKGROUND AND AIMS: Atrial fibrillation (AF) is the most common arrhythmia in elderly people, who are particularly exposed to its most severe complications, such as stroke, worsening heart failure and dementia. Some studies demonstrate that AF is associated with increased mortality in home-dwelling subjects, but little is known about the clinical impact of the arrhythmia in hospitalized patients. We studied the clinical associations and effects of AF on the 23,174 hospitalized patients enrolled in the GIFA (Gruppo Italiano di Farmacoepidemiologia nell'Anziano) Study. METHODS: Patients were divided into three groups according to the absence or presence of AF (sinus rhythm, non_AF; AF as main diagnosis, AF_main; AF as comorbid condition, AF_associated) and stratified into four age-groups (=60, 61-70, 71-80 and >80 yrs). RESULTS: AF_associated patients were older, more frequently disabled, and characterized by greater comorbidity and longer in-hospital length of stay. Urea nitrogen concentration was higher, and total cholesterol was lower in AF_associated patients, compared with the other two groups. Overall mortality was 6.0%. Mortality was higher in AF_associated patients (non_AF: 6.0% vs AF_associated: 7.1% vs AF_main: 0%, p<0.001). CONCLUSIONS: Our results suggest that, in hospitalized patients, AF as a comorbid condition is associated with worse metabolic profile and clinical outcomes, and thus, may represent a marker of frailty.

To evaluate prostate cancer (PCa) detection after repeated negative saturation biopsy, 75 patients, aged 53–78 years, underwent transurethral resection of prostate (TURP) because of persistent suspicion of cancer; median PSA was 11.8 ng ml−1 and 58 men complained lower urinary tract symptoms (LUTS). In 12 (16%) and 3 (4%) men a T1a and T1b PCa was found with median PSA and Gleason score equal to 14.2 vs 23.6 ng ml−1 and 5.6 vs 7 ng ml−1. In case of persistent suspicion of PCa after repeated negative saturation biopsy, TURP may be proposed, aside from the coexistence of LUTS, to rule out a PCa, in younger patients with high PSA values (20 ng ml−1).

- Abstract
Necrotizing fasciitis (NF) is a highly aggressive infectious process, polymicrobial in nature, involving soft tissues with a high risk of rapid spread through superficial and deep fascial planes and muscular layers. Cervical NF is quite rare, is mostly of odontogenic origin, and may be complicated by descendant mediastinitis with a very high mortality rate. Systemic conditions impairing the patient's immune competence, such as diabetes, may playa predisposing role. An effective treatment strategy includes prompt diagnosis (clinical findings, local microbiological tests, blood culture and, if deemed necessary, histopathology), broad-spectrum antibiotic therapy as early as possible which should be later adjusted according to antibiogram results, stabilization of vital functions and, if possible, elimination/treatment of predisposing factors. This paper describes a complex and emblematic case. [ABSTRACT FROM AUTHOR]

Objectives: To evaluate whether the adjunct of an ultrasound contrast medium improves the detection rate of prostate cancer.Method: In 34 patients, scheduled to undergo a trans-perineal extended prostate biopsy, we carried out a color-Doppler ultrasound (CDU) of the prostate before and after i.v. injection of Levovist®, an ultrasound contrast medium. Further bioptic samples were taken in the areas where a marked increase in vascularization was noticed.Results: The overall diagnostic sensitivity, specificity and efficiency were respectively 72.7, 56.2 and 62.9% for transrectal ultrasound (TRUS); 80, 56.2 and 65.3% for CDU and 88.8, 54.5 and 68% for CDU after Levovist® injection; 66.5, 72.6 and 65.1% for digito-rectal examination (DRE); 100, 51.4 and 65.4% for total PSA; and 100, 88.8 and 94.3% for PSA free/total. In the 16 patients with prostate carcinoma, the sensitivity of CDU after Levovist® was 92.3, 66% for both DRE and TRUS, and 80% for DRE plus TRUS.Conclusions: Considering the cost and the results obtained (high sensitivity and low specificity), a routine use of Levovist® does not seem indicated in patients undergoing prostatic biopsy. An exception may be represented by patients with both negative DRE and TRUS.Prostate Cancer and Prostatic Diseases (2003) 6, 159-162. doi:10.1038/sj.pcan.4500647 [ABSTRACT FROM AUTHOR]

- Abstract
M-dwarf stars – hydrogen-burning stars that are smaller than 60 per cent of the size of the Sun – are the most common class of star in our Galaxy and outnumber Sun-like stars by a ratio of 12:1. Recent results have shown that M dwarfs host Earth-sized planets in great numbers1,2: the average number of M-dwarf planets that are between 0.5 to 1.5 times the size of Earth is at least 1.4 per star3. The nearest such planets known to transit their star are 39 parsecs away4 , too distant for detailed follow-up observations to measure the planetary masses or to study their atmospheres. Here we report observations of GJ 1132b, a planet with a size of 1.2 Earth radii that is transiting a small star 12 parsecs away. Our Doppler mass measurement of GJ 1132b yields a density consistent with an Earth-like bulk composition, similar to the compositions of the six known exoplanets with masses less than six times that of the Earth and precisely measured densities5−11. Receiving 19 times more stellar radiation than the Earth, the planet is too hot to be habitable but is cool enough to support a substantial atmosphere, one that has probably been considerably depleted of hydrogen. Because the host star is nearby and only 21 per cent the radius of the Sun, existing and upcoming telescopes will be able to observe the composition and dynamics of the planetary atmosphere., Astronomy

- Abstract
Recent analyses1–4 of data from the NASA Kepler spacecraft5 have established that planets with radii within 25 per cent of Earth’s (R⊕) are commonplace throughout the Galaxy, orbiting at least 16.5 per cent of Sun-like stars1. Because these studies were sensitive to the sizes of the planets but not their masses, the question remains whether these Earth-sized planets are indeed similar to the Earth in bulk composition. The smallest planets for which masses have been accurately determined6,7 are Kepler-10b (1.42R⊕) and Kepler-36b (1.49R⊕), which are both significantly larger than the Earth. Recently, the planet Kepler-78b was discovered8 and found to have a radius of only 1.16R⊕. Here we report that the mass of this planet is 1.86 Earth masses. The resulting mean density of the planet is 5.57 g cm−3, which is similar to that of the Earth and implies a composition of iron and rock., Astronomy

Abstract Malignant pleural mesothelioma (MPM) arises from mesothelial cells lining the pleural cavity of asbestos‐exposed individuals and rapidly leads to death. MPM harbors loss‐of‐function mutations in BAP1, NF2, CDKN2A, and TP53, but isolated deletion of these genes alone in mice does not cause MPM and mouse models of the disease are sparse. Here, we show that a proportion of human MPM harbor point mutations, copy number alterations, and overexpression of KRAS with or without TP53 changes. These are likely pathogenic, since ectopic expression of mutant KRASG12D in the pleural mesothelium of conditional mice causes epithelioid MPM and cooperates with TP53 deletion to drive a more aggressive disease form with biphasic features and pleural effusions. Murine MPM cell lines derived from these tumors carry the initiating KRASG12D lesions, secondary Bap1 alterations, and human MPM‐like gene expression profiles. Moreover, they are transplantable and actionable by KRAS inhibition. Our results indicate that KRAS alterations alone or in accomplice with TP53 alterations likely play an important and underestimated role in a proportion of patients with MPM, which warrants further exploration.
