Streptococcus agalactiae or group B streptococcus (GBS) is a frequent pathogen in immunocompromised adults. The aim of this study was to determine the relative frequency, clinical presentation, antimicrobial susceptibility profile, and risk factors associated with GBS bacteremia in non-pregnant adult patients. We conducted a retrospective analysis of blood cultures performed in two hospitals between the years 2009-2013. From 1110 bacteremia episodes, 13 were caused by GBS, all of which were susceptible to ampicillin...

Hepatocellular carcinoma (HCC) in childhood differs from adult HCC as it is often associated with inherited liver disease. It is, however, unclear whether liver transplantation (LT) for HCC in childhood with or without associated inherited disease has a comparable outcome to adult HCC. Based on data from the European Liver Transplant Registry (ELTR) we aimed to investigate if there are differences in patient and graft survival after LT for HCC between children and adults and between patients with underlying inherited versus non inherited liver disease respectively...

Jonathan Monk, Emanuele Bosi
Genome-scale metabolic reconstructions are powerful resources that allow translation biological knowledge and genomic information to phenotypical predictions using a number of constraint-based methods. This approach has been applied in recent years to gain deep insights into the cellular phenotype role of the genes at a systems-level, driving the design of targeted experiments and paving the way for knowledge-based synthetic biology.The identification of genetic determinants underlying the variability at the phenotypical level is crucial to understand the evolutionary trajectories of a bacterial species...

Human activity and related land use change are the primary cause of accelerated soil erosion, which has substantial implications for nutrient and carbon cycling, land productivity and in turn, worldwide socio-economic conditions. Here we present an unprecedentedly high resolution (250 × 250 m) global potential soil erosion model, using a combination of remote sensing, GIS modelling and census data. We challenge the previous annual soil erosion reference values as our estimate, of 35.9 Pg yr-1 of soil eroded in 2012, is at least two times lower...

In this article, we present a novel adaptive enhanced sampling molecular dynamics (MD) method for the accelerated simulation of protein folding and aggregation. We introduce a path-variable L based on the un-biased momenta p and displacements dq for the definition of the bias s applied to the system and derive 3 algorithms: general adaptive bias MD, adaptive path-sampling, and a hybrid method which combines the first 2 methodologies. Through the analysis of the correlations between the bias and the un-biased gradient in the system, we find that the hybrid methodology leads to an improved force correlation and acceleration in the sampling of the phase space...

Measurements of the absorption coefficient of chromophoric dissolved organic matter (ay) are needed to validate existing ocean-color algorithms. In the surface open ocean, these measurements are challenging because of low ay values. Yet, existing global datasets demonstrate that ay could contribute between 30% to 50% of the total absorption budget in the 400-450 nm spectral range, thus making accurate measurement of ay essential to constrain these uncertainties. In this study, we present a simple way of determining ay using a commercially-available in-situ spectrophotometer operated in underway mode...

Methoxycarbonyl-1-phenyl-2-cyclopropylmethyl based derivatives cis-(+)-1a [cis-(+)-MR200], cis-(-)-1a [cis-(-)-MR201], and trans-(±)-1a [trans-(±)-MR204], have been identified as new potent sigma (σ) receptor ligands. In the present paper, novel enantiomerically pure analogues were synthesized and optimized for their σ receptor affinity and selectivity. Docking studies rationalized the results obtained in the radioligand binding assay. Absolute stereochemistry was unequivocally established by X-ray analysis of precursor trans-(+)-5a as camphorsulfonyl derivative 9...

BACKGROUND AND AIMS: Gallbladder carcinoma is a rare but aggressive malignant neoplasm. The incidence of intra- or post-operative incidental gallbladder carcinoma diagnosis following laparoscopic cholecystectomy is estimated to be 1-2%. Aggressive re-resection is warranted as the majority of patients have residual disease either in the liver or the lymph nodes. However the use of a minimally invasive surgical approach (MISA) to perform a radicalization in these patients has not been investigated yet...

BACKGROUND: Patients after cardiac arrest or in cardiogenic shock due to acute coronary syndrome (ACS) are at high risk for stent thrombosis (ST) and recurrent cardiovascular events after primary percutaneous coronary intervention (PCI). High post-interventional platelet reactivity (HPR) might be an additional risk factor for ST in these critically ill patients. METHODS: Between 2006 and 2016, 401 critically ill patients from a cardiologic intensive care unit underwent platelet function testing after primary PCI using whole blood impedance aggregometry...

Conjunctival melanoma (CM) is an exceptionally rare tumor, with a propensity for local and distant recurrence, with the lungs, skin, liver, and brain being the most common sites of metastasis. Recent progress in systemic treatments, with checkpoint inhibitors and targeted therapies blocking BRAF and MEK, has redefined the standard of care of advanced unresectable and metastatic melanoma. Although most trials did not include patients with conjunctival melanoma, its close molecular and genetic relationship to cutaneous melanoma might suggest a similar response to these novel agents...

Cancer radiation therapy with charged particle beams, called particle therapy, is a new therapeutic treatment presenting major advantages when compared to conventional radiotherapy. Because ions have specific ballistic properties and a higher biological effectiveness, they are superior to x-rays. Numerous medical centres are starting in the world using mostly protons but also carbon ions as medical beams. Several investigations are attempting to reduce the cost/benefit ratio and enlarge the range of therapeutic indications...

Background: Sentinel Lymphonode analysis has become a barely new and innovative way to treat early stages of endometrial cancer (Ballester et al., Lancet Oncol 469-476, 2011; Buda et al., Ann Surg Oncol 2975-81, 2016). Indocyanine green cervical injection is considered gold standard for mapping nodes' drainage. Blue dye is used as a valid alternative in many centers, due to the lower cost of execution. The objective of this video is to prove that methylene blue dye's cervical injection is a valid and "low-cost" method to obtain mapping of lymphatic drainage in patient with early endometrial cancer...

OBJECTIVES AND METHODS:  High-grade B-cell lymphoma, NOS (HGBL) have an aggressive clinical behavior and poor outcome using regimens currently employed for diffuse large B-cell lymphoma (DLBCL) such as rituximab, cyclophosphamide, doxorubicin, vincristine, and prednisone (R-CHOP). Promising results have been reported with more intensive regimens but this strategy is not suitable for elderly or unfit patients. Rituximab in association with cyclophosphamide, mitoxantrone, vincristine, etoposide, bleomycin, and prednisone (R-VNCOP-B) demonstrated high efficacy and manageable toxicity as first-line treatment for elderly aggressive non-Hodgkin lymphoma patients...

Selected circulating microRNAs (miRNAs) have been suggested for non-invasive screening of non-small cell lung cancer (NSCLC), however the numerous proposed miRNA signatures are inconsistent. Aiming to identify miRNAs suitable specifically for stage I-II NSCLC screening in serum/plasma samples, we searched the databases "Pubmed", "Medline", "Scopus", "Embase" and "WOS" and systematically reviewed the publications reporting quantitative data on the efficacy [sensitivity, specificity and/or area under the curve (AUC)] of circulating miRNAs as biomarkers of NSCLC stage I and/or II...
