#1
Gustavo C Machado, Eileen Rogan, Chris G Maher
Low back pain is a common condition seen in the ED. However, its management in this setting has received relatively little attention and there have been few efforts to develop strategies to improve emergency care of low back pain. In order to ensure that care is appropriately delivered for low back pain patients in the ED, emergency physicians must understand issues of providing low-value care and consider potential solutions to the problem. In this paper, we describe the usual emergency care provided for non-serious low back pain and present possible strategies for restructuring ED practice and approaches for changing physician and patient behaviour...

Primary intraocular lymphomas are rare tumours that can be further subdivided into primary vitreoretinal and the even rarer primary uveal lymphoma. The incidence of primary vitreoretinal lymphoma (PVRL) has increased during the last few decades. Differential diagnostic distinction between lymphoma and posterior uveitis is often difficult, so that adequate diagnosis and treatment is often delayed. This is fatal, because PVRL is often associated with primary central nervous lymphoma. To confirm the diagnosis, prior treatment of cytological or histological detection of lymphoma cells is the gold standard...

Background & Aims: To improve prognosis in patients with hepatocellular carcinoma (HCC), the molecular mechanisms of tumor thrombus formation and metastasis must be clarified. The epithelial-mesenchymal transition (EMT) and cancer stem cells (CSCs) play crucial roles in tumor invasion and metastasis. This study aimed to reveal the clinical significance of the expression of the functional CSC marker, CD13, and investigate the correlation between CD13 expression and two EMT markers, E-cadherin and vimentin...

Stone cleavers are one of the most distinctive components of the Acheulian toolkit. These tools were produced as part of a long and complex reduction sequence and they provide indications for planning and remarkable knapping skill. These aspects hold implications regarding the cognitive complexity and abilities of their makers and users. In this study we have analyzed a cleaver assemblage originating from the Acheulian site of Gesher Benot Ya'aqov, Israel, to provide a reconstruction of the chaîne opératoire which structured their production...

Genetically encoded filamentous actin probes, Lifeact, Utrophin and F-tractin, are used as tools to label the actin cytoskeleton. Recent evidence in several different cell types indicates that these probes can cause changes in filamentous actin dynamics, altering cell morphology and function. Although these probes are commonly used to visualise actin dynamics in neurons, their effects on axonal and dendritic morphology has not been systematically characterised. In this study, we quantitatively analysed the effect of Lifeact, Utrophin and F-tractin on neuronal morphogenesis in primary hippocampal neurons...

Magnusiomyces capitatus is an emerging opportunistic fungal pathogen particularly in immunocompromised patients. We report a case of a M. capitatus peritonitis in child with acute lymphocytic leukemia as a breakthrough infection during caspofungin therapy. The possibility of breakthrough infections caused by M. capitatus must be taken into consideration, particularly in immunosupressed patients being treated for systemic fungal infections by caspofungin. Although there are no defined breakpoints for susceptibility testing of M...

BACKGROUND: Bariatric surgery has proved to be an effective strategy in treating obesity. However, randomized controlled trials (RCTs) of 3 most common bariatric surgery procedures, Roux-en-Y gastric bypass (RYGB), sleeve gastrectomy (SG), and laparoscopic adjustable gastric band (LAGB), reported inconsistent results. We performed a systematic review and network meta-analysis to synthesize evidence of effectiveness of the 3 common bariatric procedures from relevant RCTs. METHODS: The present study was a systematic review and network meta-analysis of RCTs...

BACKGROUND: Parkinson's disease (PD) is a progressive disorder of the central nervous system. The prevalence of PD varies considerably by age group; it has a higher prevalence in patients aged 60 years and more. Several studies have shown that statin, a cholesterol-lowering medication, reduces the risk of developing PD, but evidence for this is so far inconclusive. The objective of this study is to evaluate the association between statin use and the risk of developing PD. METHODS: PubMed, EMBASE, and the bibliographies of articles were searched for studies published between January 1, 1990, and January 1, 2017, which reported on the association between statin use and PD...

In this study, we compared the transport characteristics of Bacillus subtilis cells and their spores in saturated porous media. Both the bacteria cells and spores were readily transported under lower ionic strengths (IS) (1mM), featuring high mass recovery rates (>75%). The bacteria cells recovery rate declined to 58.05% when the IS increased to 100mM; but the spores recovery rate remained at 74.54%. Spores appear to be more mobile than bacterial cells over wide range of IS. Surface properties and breakthrough curves analysis of the two bio-particles (cells and spores) indicated that attachment, straining and blocking mechanisms contribute differently to deposition processes...

CONTEXT: - Colorectal cancer (CRC) represents the third most-common cancer in developed countries and is a leading cause of cancer deaths worldwide. Two recognized pathways contribute to CRC development: a more-common chromosomal instability pathway and, in 15% of cases, a deficient mismatch repair or microsatellite instability-high (MSI-H) pathway. The MSI-H CRC can be associated with somatic or germline mutations. Microsatellite status has been recognized as a prognostic and predictive biomarker...

Fluorescence imaging of biological systems down to the single-molecule level has generated many advances in cellular biology. For applications within intact tissue, single-walled carbon nanotubes (SWCNTs) are emerging as distinctive single-molecule nanoprobes, due to their near-infrared photoluminescence properties. For this, SWCNT surfaces must be coated using adequate molecular moieties. Yet, the choice of the suspension agent is critical since it influences both the chemical and emission properties of the SWCNTs within their environment...

Drainage systems must be designed in a way to minimize undesired problems such as decrease in hydraulic capacity of the channel, blockage and transport of pollutants due to deposition of sediment. Channel design considering self-cleansing criteria are used to solve the sedimentation problem. Incipient deposition is one of the non-deposition self-cleansing design criteria that can be used as a conservative method for channel design. Experimental studies have been carried out in five different cross-section channels, namely trapezoidal, rectangular, circular, U-shape and V-bottom...

Soil-transmitted helminths (STHs) are a major health concern globally. Infection is mostly through contact with contaminated water, food or soil. Therefore to break the cycle of viable transmission STH eggs must be quantitatively detected in the environment. The effect of different reagents on the viability of Ascaris suum eggs during laboratory detection and quantification was assessed and different incubation solutions compared. Sulphuric acid gave a slightly higher recovery percentage of viable eggs (91...

To prevent postoperative abdominal adhesions, many new antiadhesion materials have been developed all over the world. Few studies have analyzed the thickness of antiadhesive materials, but it is an important factor in maximizing adhesion prevention. The aspect of material thickness will needed for the future studies. However, few materials proceeded further than animal experimentation. Comparison tests between the newly developed antiadhesion materials and products already on the market will make it easier to conduct clinical trials...

Aubrey Smith, Chris Rowland Hill
Acute ischaemic stroke is the second largest cause of death worldwide and a cause of major physical and psychological morbidity. Current evidence based treatment includes intravenous thrombolysis (IVT) and mechanical thrombectomy (MT), both requiring careful patient selection and to be administered as quickly as possible within a limited time window from symptom onset. Imaging plays a crucial role identifying patients who may benefit from MT or IVT whilst excluding those that maybe harmed. For IVT, imaging must as a minimum exclude haemorrhage, stroke mimics and provide an estimate of non-viable brain...

High flow nasal cannula oxygenation has distinct advantages over other oxygen devices due to its unique effects on respiratory physiology. In particular, adjustable oxygen delivery and flow-dependent carbon dioxide clearance from the upper airway reduce work of breathing and can better match inspiratory demand during respiratory distress. Historically, few studies had evaluated whether the physiologic effects of these devices translated into clinical benefit. However, recent publications have begun to address this knowledge gap...

Induction of the antioxidant enzymes catalase (CAT), peroxidase (POD) and superoxide dismutase (SOD) and the avoidance of potentially toxic metals in soil by Folsomia candida were investigated. Both laboratory-spiked and field-polluted agricultural soils were used. Cadmium (Cd) concentrations in body tissues, animal avoidance behaviour and physico-chemical properties of the field soils were also determined. In laboratory Cd-spiked soils, the CAT and SOD activities in the Cd treatments were 71.1-94.7 and 1.31-4...
