Oncolytic virotherapy promotes radiosensitivity in soft tissue sarcoma by suppressing anti-apoptotic MCL1 expression

Soft tissue sarcoma (STS) is a rare cancer that develops from soft tissues in any part of the body. Despite major advances in the treatment of STS, patients are often refractory to conventional radiotherapy, leading to poor prognosis. Enhancement of sensitivity to radiotherapy would therefore improve the clinical outcome of STS patients. We previously revealed that the tumor-specific, replication-competent oncolytic adenovirus OBP-301 kills human sarcoma cells. In this study, we investigated the radiosensitizing effect of OBP-301 in human STS cells. The in vitro antitumor effect of OBP-301 and ionizing radiation in monotherapy or combination therapy was assessed using highly radiosensitive (RD-ES and SK-ES-1) and moderately radiosensitive (HT1080 and NMS-2) STS cell lines. The expression of markers for apoptosis and DNA damage were evaluated in STS cells after treatment. The therapeutic potential of combination therapy was further analyzed using SK-ES-1 and HT1080 cells in subcutaneous xenograft tumor models. The combination of OBP-301 and ionizing radiation showed a synergistic antitumor effect in all human STS cell lines tested, including those that show different radiosensitivity. OBP-301 was found to enhance irradiation-induced apoptosis and DNA damage via suppression of anti-apoptotic myeloid cell leukemia 1 (MCL1), which was expressed at higher levels in moderately radiosensitive cell lines. The combination of OBP-301 and ionizing radiation showed a more profound antitumor effect compared to monotherapy in SK-ES-1 (highly radiosensitive) and HT1080 (moderately radiosensitive) subcutaneous xenograft tumors. OBP-301 is a promising antitumor reagent to improve the therapeutic potential of radiotherapy by increasing radiation-induced apoptosis in STS.
Investigation of nanovesicle liposome powder production from soy lecithin by spray drying

ABSTRACT Aiming to produce stable nanosize liposome vesicles (∼100 nm), in a powder form, this study investigated the use of combined microfluidization–spray drying processes, using lactose as a stabilizing agent for vesicles during the process of dehydration. To determine the effective amount of lactose for stabilization, the vesicles were prepared at three different ratios (1:1, 1:3, and 1:5) of lecithin:lactose. The physicochemical properties of the nanoliposome powder and its reconstituted solution with water were evaluated over a storage period of 90 days at water activity below 0.3. The results demonstrated that upon addition of appropriate amount of lactose (1:3 or 1:5 of lecithin:lactose ratio), the aggregation of nanoliposomes was prevented and their size was maintained at lower than 130 nm during storage. Peroxide values of all nanoliposome formulations during the storage period remained below 3 meq/kg and there was no change in L*, a*, b* color parameters. The X-ray photoelectron spectroscopy analysis showed over-representation of lecithin on the power particle surface as compared to the bulk composition.
The effect of counseling, antiretroviral therapy and relationship on disclosing HIV positive status to sexual partner among adult HIV patients in Ethiopia: A systematic review and meta-analysis

Background Human Immunodeficiency Virus (HIV) is continued as a major public health problem, especially in developing countries. Therefore, this study aimed to estimate the effect of counseling, antiretroviral therapy (ART) and relationship on disclosing HIV positive status to sexual partner among adult HIV patients in Ethiopia. Methods The Preferred Reporting Items for Systematic Review and Meta-analysis (PRISMA) was used during this review. The study included both published and unpublished studies which were conducted in Ethiopia until the end of 2019. Different electronic databases (PubMed, Cochrane library, CINAHL, Global Health, HINARI and Google scholar) were searched. Data were extracted in Microsoft Excel sheet and STATA/SE 14 was used to meta-analysis. I2 and Egger test statistics were used to test heterogeneity and publication bias respectively. Results Twenty-two articles with 8,873 adult HIV infected peoples were included in this systematic review and meta-analysis. The pooled magnitude of disclosing HIV status to sexual partner was 74.63% [95% CI: (67.79, 81.47)]. Counseled [AOR = 4.96, 95% CI: (2.87, 8.55)], ART initiated [AOR = 4.78, 95% CI: (3.84, 5.94)] and who had a smooth relationship before HIV testing [AOR = 6.82, 95% CI: (3.49, 13.33)] were significantly associated with disclosing HIV status to sexual partner. Conclusions Disclosing HIV positive status to sexual partner in Ethiopia was low as the government invested in partner notification. Counseling, ART initiation and smooth relationship before HIV testing were significantly associated with disclosing HIV status to sexual partner. The government needs to strengthen pre and post HIV test counseling even after treatment started to increase disclosing status. Registration The protocol of this systematic review and meta-analysis was registered in the PROSPERO with a specific registration number: CRD42020161276; https://clinicaltrials.gov/.
Improved privacy preserving method for periodical SRS publishing

Spontaneous reporting systems (SRSs) are used to collect adverse drug events (ADEs) for their evaluation and analysis. Periodical SRS data publication gives rise to a problem where sensitive, private data can be discovered through various attacks. The existing SRS data publishing methods are vulnerable to Medicine Discontinuation Attack(MD-attack) and Substantial symptoms-attack(SS-attack). To remedy this problem, an improved periodical SRS data publishing—PPMS(k, θ, ɑ)-bounding is proposed. This new method can recognize MD-attack by ensuring that each equivalence group contains at least k new medicine discontinuation records. The SS-attack can be thwarted using a heuristic algorithm. Theoretical analysis indicates that PPMS(k, θ, ɑ)-bounding can thwart the above-mentioned attacks. The experimental results also demonstrate that PPMS(k, θ, ɑ)-bounding can provide much better protection for privacy than the existing method and the new method dose not increase the information loss. PPMS(k, θ, ɑ)-bounding can improve the privacy, guaranteeing the information usability of the released tables.
Nursing strategies to support psychological adaptation in adult cancer patients: a scoping review.

OBJECTIVE To map the scientific evidence published in the literature about nursing strategies and intervention programs directed at supporting psychological adaptation in adult cancer patients. METHOD A scoping review based on Joanna Briggs Institute Reviewers' Manual 2015 Methodology for JBI Scoping Reviews was conducted. Twelve databases were searched between 1 January 2012 and 31 January 2019. RESULTS From 2203 studies, 32 were included. Evidence was grouped in five subjects: procedures, outcome assessment measures, nursing feasibility, effectiveness and cost-effectiveness. The cognitive-behavioral therapy was most frequent intervention. These interventions were developed between 5 to 10 weeks, included 3 to 6 sessions and lasted up to 60 minutes. Despite a wide range of outcome measures employed, three main areas were identified, adjustment and coping; stress, anxiety and fear of recurrence; and quality of life. CONCLUSION This review allowed to identify nursing strategies to support psychological adaptation in adult cancer patients, to assess vulnerabilities and difficulties related to nurse interventions and to recognize the need for further insights into the effectiveness and cost-effectiveness.
Toward a comparison and an optimization of CT protocols using new metrics of dose and image quality part I: prediction of human observers using a model observer for detection and discrimination tasks in low-dose CT images in various scanning conditions

In the context of reducing the patient dose coming from CT scanner examinations without penalizing the diagnosis, the assessment of both patient dose and image quality (IQ) with relevant metrics is crucial. The present study represents the first stage in a larger work, aiming to compare and optimize CT protocols using dose and IQ new metrics. We proposed here to evaluate the capacity of the Non-PreWhitening matched filter with an eye (NPWE) model observer to be a robust and accurate estimation of IQ. We focused our work on two types of clinical tasks: a low contrast detection task and a discrimination task. We designed a torso-shaped phantom, including Plastic Water® slabs with cylindrical inserts of different diameters, sections and compositions. We led a human observer study with 13 human observers on images acquired in multiple irradiation and reconstruction scanning conditions (voltage, pitch, slice thickness, noise level of the reconstruction algorithm, energy level in dual-energy mode and dose), to evaluate the behavior of the model observer compared to the human responses faced to changing conditions. The model observer presented the same trends as the human observers with generally better results. We rescaled the NPWE model on the human responses by scanning conditions (kVp, pitch, slice thickness) to obtain the best agreement between both observer types, estimated using the Bland-Altman method. The impact of some scanning parameters was estimated using the correct answer rate given by the rescaled NPWE model, for both tasks and each insert size. In particular, the comparison between the dual-energy mode at 74 keV and the single-energy mode at 120 kVp showed that, if the 120 kVp voltage provided better results for the smallest insert at the lower doses for both tasks, their responses were equivalent in many cases.
Identification of Lumican and Fibromodulin as Hub Genes Associated with Accumulation of Extracellular Matrix in Diabetic Nephropathy

Introduction: Diabetic nephropathy (DN) remains a major cause of end-stage renal disease. The development of novel biomarkers and early diagnosis of DN are of great clinical importance. The goal of this study was to identify hub genes with diagnostic potential for DN by weighted gene co-expression network analysis (WGCNA). Methods: Gene Expression Omnibus database was searched for microarray data including distinct types of CKD. Gene co-expression network was constructed, and modules specific for DN were identified by WGCNA. Gene ontology (GO) analysis was performed, and the hub genes were screened out within the selected gene modules. In addition, cross-validation was performed in an independent dataset and in samples of renal biopsies with DN and other types of glomerular diseases. Results: Dataset GSE99339 was selected, and a total of 179 microdissected glomeruli samples were analyzed, including DN, normal control, and 7 groups of other glomerular diseases. Twenty-three modules of the total 10,947 genes were grouped by WGCNA, and a module was specifically correlated with DN (r = 0.54, p = 9e−15). GO analysis showed that module genes were mainly enriched in the accumulation of extracellular matrix (ECM). LUM, ELN, FBLN1, MMP2, FBLN5, and FMOD were identified as hub genes. Cross verification showed LUM and FMOD were higher in the DN group and were negatively correlated with estimated glomerular filtration rate (eGFR). In renal biopsies, expression levels of LUM and FMOD were higher in DN than IgA nephropathy, membranous nephropathy, and normal controls. Conclusion: By using WGCNA approach, we identified LUM and FMOD related to ECM accumulation and were specific for DN. These 2 genes may represent potential candidate diagnostic biomarkers of DN.
How to build a fast and accurate code-modulated brain-computer interface

Objective. In the last decade, the advent of code-modulated brain-computer interfaces (BCIs) has allowed the implementation of systems with high information transfer rates (ITRs) and increased the possible practicality of such interfaces. In this paper, we evaluate the effect of different numbers of targets in the stimulus display, modulation sequences generators, and signal processing algorithms on the accuracy and ITR of code-modulated BCIs. Approach. We use both real and simulated electroencephalographic (EEG) data, to evaluate these parameters and methods. Then, we compared numerous different setups to assess their performance and identify the best configurations. We also evaluated the dependability of our simulated evaluation approach. Main results. Our results show that Golay, almost perfect, and deBruijn sequence-based visual stimulus modulations provide the best results, significantly outperforming the commonly used m-sequences in all cases. We conclude that artificial neural network processing algorithms offer the best processing pipeline for this type of BCI, achieving a maximum classification accuracy of 94.7% on real EEG data while obtaining a maximum ITR of 127.2 bits min−1 in a simulated 64-target system. Significance. We used a simulated framework that demonstrated previously unattainable flexibility and convenience while staying reasonably realistic. Furthermore, our findings suggest several new considerations which can be used to guide further code-based BCI development.
TSC2 Interacts with HDLBP/Vigilin and Regulates Stress Granule Formation

Tuberous sclerosis complex (TSC) is caused by mutations of either the TSC1 or TSC2 tumor suppressor gene. TSC causes tumors of the brain, heart, kidney, skin and lymphangioleiomyomatosis (LAM). Here we report that the TSC2 protein physically binds to high-density lipoprotein binding protein (HDLBP), also called vigilin, a core stress granule (SG) protein, and that TSC2 localizes to SGs. SGs contain mRNAs and translation initiation complexes, and regulate gene expression by sequestering specific transcripts, thereby serving a cytoprotective role. TSC2 has never before been shown to localize to SGs and knocking down vigilin impacts SG translocation of TSC2. TSC2-deficient cells showed a striking increase in the number of SGs after thermal shock and arsenite treatment relative to Tsc2-expressing cells. Our findings also show that murine kidney lysates from a model of TSC have increased levels of SG components including G3BP1 and Caprin1. G3BP1 and Caprin are elevated in renal angiomyolipomas (a renal tumor common in patients with TSC) compared with control normal kidney. G3BP1 is also elevated in TSC-associated subependymal giant cell astrocytomas. We found that genetic inhibition of G3BP1 inhibits the proliferation of TSC2-deficient cells in vitro. Finally, in a mouse model of TSC, genetic inhibition of SGs suppresses cell growth, suggesting that targeting SGs may have efficacy in the therapy of TSC. Implications: This study demonstrates that TSC2 physically interacts with HDLBP/vigilin, a component of SGs, that TSC2 localizes to SG and that TSC2-deficient cells have more SGs, suggesting that SGs represent a novel therapeutic target in TSC.
Emergency tracheostomy management cognitive aid

Tracheostomies may be inserted to assist weaning from ventilation or to aid airway management. Complications occur in up to 40% of patients, with tube displacement, tube obstruction, pneumothorax and haemorrhage most common. Prevention and management of tracheostomy emergencies requires multidisciplinary teamwork, a standardised approach, education, equipment, patient and carer involvement, and effective clinical governance. The use of clinical decision supports such as cognitive aids also improves performance, supports education, and guides quality improvement. The British National Tracheostomy Safety Project has developed extensive resources including emergency algorithms and bedhead signs. We report on the development of an emergency tracheostomy management (ETM) cognitive aid at our institution (Figure 1). The aid is not intended to be used in laryngectomy emergencies. Austin Health is a tertiary referral hospital with multiple different services involved in tracheostomy care. The intensive care unit (ICU), Department of Anaesthesia, and several surgical units including maxillofacial, thoracic, and ear nose and throat (ENT) provide care for patients with tracheostomies. Two state services, the Victorian Respiratory Support Service (VRSS) and the Victorian Spinal Cord Service (VSCS), also based at Austin Health, provide care to tracheostomy patients with complex ventilation needs and spinal injuries, respectively. The Austin Tracheostomy Review and Management Service (TRAMS) was established in 2002 as a multidisciplinary consultative service. TRAMS coordinates tracheostomy care, management guidelines and education across all disciplines at Austin Health and is a founding member of the Global Tracheostomy Collaborative (GTC). In addition, the departments of anaesthesia and intensive care undertake specific airway education and co-ordination of airway emergencies. Cognitive aids are tools that enable an experienced individual or team to perform reliably, avoiding both fixation and key omissions. They have been described as implementation tools intended to be used in real time and should be distinguished from foundation tools which contain more detailed background information targeting novices. Cognitive aids must be aligned with current best practice and introduced with an education and training campaign so that they are familiar and useable in emergency situations. By developing a shared mental model, cognitive aids support team communication and facilitate transfer of leadership when required. The key steps of cognitive aid development include staff familiarisation, implementation and long-term cultural change. Developing a cognitive aid for tracheostomy emergencies is particularly complex (see Table 1). The Austin Health code blue team responds to all airway emergencies and includes an intensive care trainee, an anaesthetic trainee, a medical trainee and a senior ICU nurse. The amount of direct experience in managing tracheostomy emergencies may vary and while code blue team members are expected to have
Development of the Ultralight Hybrid Pneumatic Artificial Muscle: Modelling and optimization

Pneumatic artificial muscles (PAMs) are one of the key technologies in soft robotics, and they enable actuation in mobile robots, in wearable devices and exoskeletons for assistive and rehabilitative purposes. While they recently showed relevant improvements, they still present quite low payload, limited bandwidth, and lack of repeatability, controllability and robustness. Vacuum-based actuation has been recently demonstrated as a very promising solution, and many challenges are still open, like generating at the same time a large contraction ratio, and a high blocking force with enhanced axial stiffness. In this paper, a novel Ultralight Hybrid PAM (UH-PAM), based on bellow-type elastomeric skin and vacuum actuation, is presented. In particular, open-cell foam is exploited as a structural backbone, together with plastic rings, all embedded in a thin skin. The design and optimization combine numerical, analytical, and experimental data. Both static and dynamic analysis are performed. The weight of the optimized actuator is only 20 g. Nevertheless, a contraction ratio up to 50% and a maximum payload of 3 kg can be achieved. From a dynamic point of view, a rise time of 0.5 s for the contraction phase is observed. Although hysteresis is significant when using the whole contraction span, it can be reduced (down to 11.5%) by tuning both the vacuum range and the operating frequency for cyclic movements. Finally, to demonstrate the potentiality of this soft actuation approach, a 3 DoFs Stewart platform is built. The feasibility of performing smooth movements by exploiting open-loop control is shown through simple and more complex handwriting figures projected on the XY plane.
Continuous fabrication of multi-stimuli responsive graphene oxide composite hydrogel fibres by microfluidics

Microfluidics appeared in the 1990s as a promising technology and has received considerable attention in developing stimuli-responsive hydrogel fibres in microscale for tissue engineering and actuation devices. In this work, thermo- and electro-responsive graphene oxide/poly(N-isopropylacrylamide)/sodium alginate (GO/PNIPAM/SA) hydrogel fibres were prepared via microfluidics and off-chip free radical polymerization. The composite hydrogel fibres were characterised using FTIR, SEM, and DSC. The thermo-triggered volume-phase transition and electrically triggered bending behaviours were also investigated. The results show that the hydrogel fibres have porous internal structures and the pore size becomes smaller with the increase of GO content due to the hydrogen bonding between the amide groups of PNIPAM chains and oxygen-containing groups on the GO nanosheets. Besides this, the incorporation of increased GO content enlarges the swelling ratio of the hydrogel fibre. The hydrogel fibres also exhibit bending behaviour under the non-contact direct current electric field.
Environmental Taxes and Economic Growth with Multiple Growth Engines

Abstract We develop an endogenous growth model in which long-run growth is driven by three engines: private abatement R&D, expanding-variety R&D, and capital accumulation. We show that an environmental tax activates private abatement by directing researchers from the variety R&D sector to the abatement R&D sector, which helps the economy avoid the environmental disaster. Our results also show that the effect of the environmental tax on long-run growth is uncertain, depending mainly on the relative productivity between the two R&D sectors. If the abatement R&D sector is sufficiently productive, increasing the environmental tax will enhance the balanced output growth rate and social welfare.
