REVIEW
Antonella Gentile, Francesco Ruffino, Maria Grazia Grimaldi
Due to their peculiar qualities, metal-based nanostructures have been extensively used in applications such as catalysis, electronics, photography, and information storage, among others. New applications for metals in areas such as photonics, sensing, imaging, and medicine are also being developed. Significantly, most of these applications require the use of metals in the form of nanostructures with specific controlled properties. The properties of nanoscale metals are determined by a set of physical parameters that include size, shape, composition, and structure...

Multimodal imaging probes can provide diagnostic information combining different imaging modalities. Nanoparticles (NPs) can contain two or more imaging tracers that allow several diagnostic techniques to be used simultaneously. In this work, a complex coacervation process to produce core-shell completely biocompatible polymeric nanoparticles (HyCoS) for multimodal imaging applications is described. Innovations on the traditional coacervation process are found in the control of the reaction temperature, allowing a speeding up of the reaction itself, and the production of a double-crosslinked system to improve the stability of the nanostructures in the presence of a clinically relevant contrast agent for MRI (Gd-DTPA)...

Background Catheter ablation of atrial fibrillation is typically performed with uninterrupted anticoagulation with warfarin or interrupted non-vitamin K antagonist oral anticoagulant therapy. Uninterrupted anticoagulation with a non-vitamin K antagonist oral anticoagulant, such as dabigatran, may be safer; however, controlled data are lacking. We investigated the safety of uninterrupted dabigatran versus warfarin in patients undergoing ablation of atrial fibrillation. Methods In this randomized, open-label, multicenter, controlled trial with blinded adjudicated end-point assessments, we randomly assigned patients scheduled for catheter ablation of paroxysmal or persistent atrial fibrillation to receive either dabigatran (150 mg twice daily) or warfarin (target international normalized ratio, 2...

BACKGROUND: Hepatocellular carcinoma (HCC) is very rare in children and is traditionally associated with a poor prognosis because many patients are not amenable to conventional resection, even in the absence of metastatic disease. For patients with locally advanced or metastatic tumors, conventional chemotherapy appears to offer limited survival benefits. PATIENTS AND METHODS: We report a case series of five consecutive pediatric patients with HCC who were treated with bevacizumab along with conventional platinum-based chemotherapy...

Oleandrin is a glycoside that inhibits the ubiquitous enzyme Na(+)-K(+)-ATPase. In addition to its known effects on cardiac muscle, recent in vitro and in vivo evidence highlighted potential for anticancer properties of this compound. In this paper we evaluated for the first time the effect of oleandrin on brain tumors. To this aim mice were transplanted with human or murine glioma and analyzed for tumor progression upon oleandrin treatment. In both systems, oleandrin impaired glioma development, reduced tumor size, and inhibited cell proliferation...

PURPOSE: To report the vitamin D status in adults from seven European countries and to identify behavioural correlates. METHODS: In total, 1075 eligible adult men and women from Ireland, Netherlands, Spain, Greece, UK, Poland and Germany, were included in the study. RESULTS: Vitamin D deficiency and insufficiency, defined as 25-hydroxy vitamin D3 (25-OHD3) concentration of <30 and 30-49.9 nmol/L, respectively, were observed in 3.3 and 30...

The application of algae to the most meaningful fields of our life, such as food, environment and energy, finds a further confirmation in the extension of this application to cultural heritage protection. In this letter, we present the results of a preliminary study testing how a polysaccharide extracted from algal matrix can restore degraded paper giving back it mechanical strength and chemical structure.

Severe sepsis and septic shock are major causes of morbidity and mortality in patients entering the emergency department (ED) or intensive care unit (ICU). Despite substantial efforts to improve patient outcome, treatment of sepsis remains challenging to clinicians. In this context, early goal directed therapy (EGDT) represents an important concept emphasizing both early recognition of sepsis and prompt initiation of a structured treatment algorithm. As part of the AME evidence series on sepsis, we conducted a systematic review of all randomized controlled EGDT trials...

Since 1970, TiO2 photocatalysis has been considered a possible alternative for sustainable water treatment. This is due to its material stability, abundance, nontoxicity and high activity. Unfortunately, its wide band gap (≈3.2 eV) in the UV portion of the spectrum makes it inefficient under solar illumination. Recently, so-called "black TiO2" has been proposed as a candidate to overcome this issue. However, typical synthesis routes require high hydrogen pressure and long annealing treatments. In this work, we present an industrially scalable synthesis of TiO2-based material based on laser irradiation...

More than 50 laboratories offer pharmacogenetic testing in France. These tests are restricted to a limited number of indications: prevention of serious adverse drug reactions; choice of most appropriate therapeutic option; dose adjustment for a specific drug. A very small proportion of these tests are mentioned in drug information labeling and the data provided (if any) are generally insufficient to ascertain whether a test is required and if it is useful. This article discusses the rationale for evaluating the performance and clinical usefulness of pharmacogenetics and provides, on behalf of the French national network of pharmacogenetics (RNPGx), three levels of recommendation for testing: essential, advisable, and possibly helpful...

Metastatic uveal melanoma is a rare malignancy with a poor prognosis. To date, systemic therapy has been ineffective; however, there are few data on the benefits of anti-CTLA4 or anti-PD-1 antibodies in sequence with liver-directed therapy. A retrospective cohort analysis was carried out on 37 consecutive patients managed in a tertiary referral centre examining the safety and efficacy of treatment; patterns of care; and impact on survival. The sequential treatment with transarterial chemotherapy (TAC), systemic immunotherapy (IT) and systemic chemotherapy was reviewed...

Autophagy activation is characterized by the accumulation of double-membrane autophagic vesicles (autophagosomes) in the cytoplasm. The mere presence of autophagosomes in the cytoplasm does not necessarily indicate an increased level of autophagy, since the blockade of any step downstream of autophagosome formation increases the number of autophagosomes. Therefore, quantitative methods for the detection of cytoplasmic protein turnover should be employed in addition to autophagosome monitoring, to verify increased levels of autophagy...

PURPOSE: Few outcome data are available about temperature management after intraoperative cardiac arrest (IOCA). We describe targeted temperature management (TTM) (32-34 °C) modalities, adverse events, and association with 1-year functional outcome in patients with IOCA. METHODS: Patients admitted to 11 ICUs after IOCA in 2008-2013 were studied retrospectively. The main outcome measure was 1-year functional outcome. RESULTS: Of the 101 patients [35 women and 66 men; median age, 62 years (interquartile range, 42-72)], 68 (67...

BACKGROUND: There is insufficient research into the use of mechanical ventilation with increased inspiratory oxygen concentration (FiO2) and fluid resuscitation with hypertonic saline solution in patients with septic shock. We tested whether these interventions are associated with reduced mortality. METHODS: This two-by-two factorial, multicentre, randomised, clinical trial (HYPERS2S) recruited patients aged 18 years and older with septic shock who were on mechanical ventilation from 22 centres in France...

For vancomycin therapy of severe infections, the Infectious Diseases Society of America recommends high vancomycin trough levels, whose potential for inducing nephrotoxicity is controversial. We evaluated the incidence and risk factors of acute kidney injury (AKI) in critically ill patients given continuous intravenous vancomycin with target serum vancomycin levels of 20 to 30 mg/L.We retrospectively studied 107 continuous intravenous vancomycin treatments of ≥48 hours' duration with at least 2 serum vancomycin levels ≥20 mg/L in critically ill patients...
