BACKGROUND: Electronic Consultation (e-consults) can provide improved access, enhance patient and provider satisfaction, and reduce beneficiary travel expenses. We explored how e-consults were implemented across three specialty areas, diabetes (Diab), gastroenterology (GI), and neurosurgery (Neuro), at two Veterans Affairs hospitals in terms of strategies for use and time-lines. METHODS: We conducted observations and electronically shadowed patient e-consultations submitted to a specialty care service by primary care provider(s) at the two sites during a thirteen-month period...

CD40 agonists bind the CD40 molecule on antigen-presenting cells and activate them to prime tumor-specific CD8(+) T cell responses. Here, we study the antitumor activity and mechanism of action of a nonreplicating adenovirus encoding a chimeric, membrane-bound CD40 ligand (ISF35). Intratumoral administration of ISF35 in subcutaneous B16 melanomas generates tumor-specific, CD8(+) T cells that express PD-1 and suppress tumor growth. Combination therapy of ISF35 with systemic anti-PD-1 generates greater antitumor activity than each respective monotherapy...

The aim of the present study was to determine the effects of curcumin on antioxidants using a rat model of type 1 diabetes. Seven‑week‑old male Sprague‑Dawley rats were injected with Streptozotocin (STZ) intraperitoneally to induce this model, and then treated with 1.0% curcumin (weight ratio) mixed in their diet for 21 days. The present study included three groups: Control group (NC), diabetic rat model group (DC) and a curcumin treated group (Diab‑Cur). The results demonstrated that curcumin treatment markedly decreased the blood glucose levels, plasma malondialdehyde concentration and plasma activity of glutathione peroxidase (GSH‑Px) and catalase (CAT); however, it increased the plasma superoxide dismutase (SOD) and insulin levels...

M Sala, R Diab, A Elaissari, H Fessi
During the past decades, lipid nanocarriers are gaining momentum with their multiple advantages for the management of skin diseases. Lipid nanocarriers enable to target the therapeutic payload to deep skin layers or even to reach the blood circulation making them a promising cutting-edge technology. Lipid nanocarriers refer to a large panel of drug delivery systems. Lipid vesicles are the most conventional, known to be able to carry lipophilic and hydrophilic active agents. A variety of lipid vesicles with high flexibility and deformability could be obtained by adjusting their composition; namely ethosomes, transfersomes and penetration enhancer lipid vesicles which achieve the best results in term of skin permeation...

Pre-clinical mouse models suggest that the gut microbiome modulates tumor response to checkpoint blockade immunotherapy; however, this has not been well-characterized in human cancer patients. Here we examined the oral and gut microbiome of melanoma patients undergoing anti-PD-1 immunotherapy (n=112). Significant differences were observed in the diversity and composition of the patient gut microbiome of responders (R) versus non-responders (NR). Analysis of patient fecal microbiome samples (n=43, 30R, 13NR) showed significantly higher alpha diversity (p<0...

The psychogenic loss of hearing is characterized by its impairment in the absence of anatomically and physiologically significant changes. These disorders are poorly represented in the scientific literature in comparison with the organic lesions. They are especially frequently overlooked in the children and adolescents. The objective of the present review was to analyze the literature publications concerning this problem and to report two clinical observations of the pathology in question. It is concluded that the clinically significant discrepancy between the audiological symptoms and the results obtained by the objective methods for hearing evaluation should be interpreted with great caution and raise the suspicion of the disease...

INTRODUCTION: We present a very unusual case in which a high-school student was admitted to our cardiac center unconscious and intubated after suffering from out of hospital SCD. There was no history of fever, substance abuse, family history of sudden cardiac death and/or coronary artery disease, arthralgia, hypercoagulable state or familial hyperlipidemia. An emergent coronary angiogram revealed diffuse obstructive coronary artery disease which was treated with several stents. The following days of his admission were characterized by hemodynamic instability, necessitating temporary support via extracorporeal membrane oxygenation (ECMO), from which he was weaned off at a later stage...

BACKGROUND: Current guidelines advocate immediate vs. non-immediate percutaneous coronary intervention (PCI) strategy in ST elevation vs. non ST elevation myocardial infarction (STEMI, NSTEMI). There is however increasing concern that "next-day PCI" in NSTEMI may adversely affect LV systolic and/or diastolic function and a more urgent aggressive approach should be taken in NSTEMI, similar to that in STEMI. In the current study we compared echocardiographic data between patients with STEMI and NSTEMI who had either primary or early PCI respectively...

Electrohysterogram source imaging, i.e., moving from the electrode/sensor space to the source space using EHG signals, provide an estimate of spatial distributions of uterine activity at millisecond scale. This paper aims to study the ability of different distributed source localization methods to recover uterine electrical activity sources. Performance was quantified using a detection accuracy index. Our result suggests that the variation based method is able to reconstruct extended uterus sources with the overall high accuracy, where the increasing of the electrodes numbers and the decreasing of the fat thickness induce a better accuracy in localization...

The COPI coat forms transport vesicles from the Golgi complex and plays a poorly defined role in endocytic trafficking. Here we show that COPI binds K63-linked polyubiquitin and this interaction is crucial for trafficking of a ubiquitinated yeast SNARE (Snc1). Snc1 is a v-SNARE that drives fusion of exocytic vesicles with the plasma membrane, and then recycles through the endocytic pathway to the Golgi for reuse in exocytosis. Removal of ubiquitin from Snc1, or deletion of a β'-COP subunit propeller domain that binds K63-linked polyubiquitin, disrupts Snc1 recycling causing aberrant accumulation in internal compartments...

This article sets out to investigate the role played by the rainforest of Central Africa in providing environmental goods and services, regulating and stabilizing the global climate as well as participating in socio-economic development of the riparian countries. This complex role offers a double status, almost confrontational, to this rainforest: it stands as an economic resource and as a major global climate regulator. Hence, there is an urgent need to question certain aspects such as climate trends in this strategic region and the use of local forest resources for economic purpose in order to suggest ecological attitudes to be adopted by policymakers, stakeholders, forest professionals and users for a sustainable development...

Multi-component nanostructures of Au-CdS-ZnO with a novel morphology were synthesized by a non-conventional strategy where seeded growth is combined with solution-liquid-solid (SLS) growth. Each of these synthetic routes is used for growing a different domain of the final heterostructure, where ZnO rods are grown first on Au nanoparticles via heterogeneous nucleation while CdS is later grown between these two domains via SLS, using the Au tip of the preformed Au-ZnO as a catalyst. The in situ alloying of the Au tip with Cd enabled the metal tip to function as an SLS catalyst at a relatively mild reaction temperature which is lower than the melting point of pure Au...

Raw milk has recently been reported as a source of extended-spectrum beta-lactamase (ESBL) and carbapenemase genes. We thus investigated the prevalence of ESBL- and carbapenemase-producing Enterobacteriaceae in raw milk in Lebanon in order to assess the risk of transfer of these bacteria to humans. A high prevalence (30.2 %) of CTX-M-15-producing K. pneumoniae was detected in raw bovine milk. Three main K. pneumoniae clones were identified by PFGE and MLST typing. Southern blot experiments revealed that one of these clones carried the blaCTX-M-15 gene chromosomally...

Chronic granulomatous disease (CGD) is a rare primary immune deficiency caused by mutations in genes coding for components of the nicotinamide adenine dinucleotide phosphate oxidase, characterized by severe and recurrent bacterial and fungal infections, together with inflammatory complications. Dysregulation of inflammatory responses are often present in this disease and may lead to granulomatous lesions, most often affecting the gastrointestinal (GI) and urinary tracts. Treatment of inflammatory complications usually includes corticosteroids, whereas antimicrobial prophylaxis is used for infection prevention...

Recent studies report that outdoor air pollution will become the main environmental cause of premature death over the next few decades (OECD, 2012; WHO, 2014; World Bank, 2016). Cities are considered hot spots and urban populations are particularly exposed. There is therefore an urgent need to adapt urban systems and urban design to tackle this issue. While most European cities have introduced measures to reduce emissions, action is still required to reduce concentrations and exposure, and a holistic approach to urban design is badly needed...

OBJECTIVES: Current sizing strategies suggest valve selection based on annulus diameter despite supra-annular placement of biological prostheses potentially allowing placement of a larger size. We assessed the frequency of selecting a larger prosthesis if prosthesis size was selected using a replica (upsizing) and evaluated its impact on haemodynamics. METHODS: We analysed all discharge echocardiograms between June 2012 and June 2014, where a replica sizer was used for isolated aortic valve replacement (Epic Supra: 266 patients, Trifecta: 49 patients)...
