REVIEW
Juan Nicolas Useche, Sonia Bermudez
Conventional neuroimaging is still the mainstay in the assessment of the acute, follow-up, and chronic settings of concussion and mild traumatic brain injury (mTBI). Computed tomography (CT) is preferred for the initial assessment of acute mTBI, repeat evaluation in acute mTBI with neurologic deterioration, and cautious use in children with mTBI. Clinical rules have been developed to identify pediatric and adult patients with mTBI who can safely forego CT. Magnetic resonance (MR) imaging is mostly used in patients with acute mTBI when initial or follow-up CT is normal and there are persistent neurologic findings and in subacute or chronic mTBI...

REVIEW
Christian A Bermudez, D Michael McMullan
Increased experience with extracorporeal life support (ECLS) as a mode of cardiac support has expanded its use to diverse patient populations including patients requiring a bridge to heart transplantation and patients requiring posttransplant support for primary graft dysfunction (PGD). The use of ECLS is associated with acceptable outcomes in well-selected patients. While outcomes with the use of extracorporeal membrane oxygenation (ECMO) as a bridge to heart transplant have been variable, several series have confirmed the safe use of ECLS to stabilize patients prior to left ventricular assist device (LVAD) implantation...

In this work we present and evaluate a radiochemical procedure optimised for the analysis of (236)U and (239,240)Pu in seawater samples by Accelerator Mass Spectrometry (AMS). The method is based on Fe(OH)3 co-precipitation of actinides and uses TEVA® and UTEVA® extraction chromatography resins in a simplified way for the final U and Pu purification. In order to improve the performance of the method, the radiochemical yields are analysed in 1 to 10L seawater volumes using alpha spectrometry (AS) and Inductively Coupled Plasma Mass Spectrometry (ICP-MS)...

Family therapists know that clinical concerns are not separate from larger sociopolitical contexts. Attunement to clients' sociocultural experience is foundational to good practice, yet few guidelines integrate attention to the larger societal processes or address social equity. The purpose of this article is to help therapists move from knowing about sociocontextual issues to doing socioculturally attuned practice. We offer an overarching framework that returns to Bateson and the roots of family therapy through a call for third order transformation...

Colloidal quantum dots are emerging solution-processed materials for large-scale and low-cost photovoltaics. The recent advent of quantum dot inks has overcome the prior need for solid-state exchanges that previously added cost, complexity, and morphological disruption to the quantum dot solid. Unfortunately, these inks remain limited by the photocarrier diffusion length. Here we devise a strategy based on n- and p-type ligands that judiciously shifts the quantum dot band alignment. It leads to ink-based materials that retain the independent surface functionalization of quantum dots, and it creates distinguishable donor and acceptor domains for bulk heterojunctions...

Rational strategies for obtaining malaria vaccine candidates should include not only a proper selection of target antigens for antibody stimulation, but also a versatile molecular design based on ordering the right pieces from the complex pathogen molecular puzzle towards more active and functional immunogens. Classical Plasmodium falciparum antigens regarded as vaccine candidates have been selected as model targets in this study. Among all possibilities we have chosen epitopes of PfCSP, STARP; MSA1 and Pf155/RESA from pre- and erythrocyte stages respectively for designing a large 82-residue chimeric immunogen...

BACKGROUND: Elderly patients regularly receive bare-metal stents (BMS) instead of drug-eluting stents (DES) to shorten the duration of double antiplatelet therapy (DAPT). The aim of this study was to compare outcomes between these two types of stents with a short duration of DAPT in such patients. METHODS: In this randomised single-blind trial, we recruited patients from 44 centres in nine countries. Patients were eligible if they were aged 75 years or older; had stable angina, silent ischaemia, or an acute coronary syndrome; and had at least one coronary artery with a stenosis of at least 70% (≥50% for the left main stem) deemed eligible for percutaneous coronary intervention (PCI)...

INTRODUCTION: Low levels of thyroid hormones, total triiodothyronine (T3) and free triiodothyronine (FT3) in haemodialysis patients is a marker of malnutrition and inflammation and are predictors of mortality. The aim of this study was to determine the prevalence of malnutrition-inflammation complex syndrome in haemodialysis and its relationship with the thyroid hormones thyrotropin, T3, FT3 and free thyroxine (FT4), as well as to evaluate the prevalence of low FT3 syndrome and its correlation with nutritional and inflammatory markers...

Canine kobuviruses (CaKoVs) were first identified in diarrhoeic and asymptomatic dogs in 2011 in the USA. Subsequent studies have demonstrated a worldwide distribution of these viruses, but it is not clear if CaKoVs play a role as enteric pathogens of dogs. More recently, CaKoV RNA has been detected in wild carnivores, including red fox, golden jackal, side-striped jackal and spotted hyena. In this study, we addressed the hypothesis that wolves are susceptible to CaKoV infections. A total of 185 wolf stool samples were collected from necropsied animals and from transects in the Liguria, Piemonte and Valle D'Aosta regions of Italy, and CaKoV RNA was identified in two of these specimens...

We introduce the Interaction Factor (IF), a measure for quantifying the interaction of molecular clusters in super-resolution microscopy images. The IF is robust in the sense that it is independent of cluster density, and it only depends on the extent of the pair-wise interaction between different types of molecular clusters in the image. The IF for a single or a collection of images is estimated by first using stochastic modelling where the locations of clusters in the images are repeatedly randomized to estimate the distribution of the overlaps between the clusters in the absence of interaction (IF = 0)...

Circulating tumor-derived extracellular vesicles (EVs) have emerged as a promising source for identifying cancer biomarkers for early cancer detection. However, the clinical utility of EVs has thus far been limited by the fact that most EV isolation methods are tedious, nonstandardized, and require bulky instrumentation such as ultracentrifugation (UC). Here, we report a size-based EV isolation tool called ExoTIC (exosome total isolation chip), which is simple, easy-to-use, modular, and facilitates high-yield and high-purity EV isolation from biofluids...
