Abstract
Background
Suspending ordinary care activities during the COVID-19 pandemic made it necessary to find alternative routes to comply with care recommendations not only for acute health needs but also for patients requiring follow-up and multidisciplinary visits. We present the ‘Contactless’ model, a comprehensive operational tool including a plurality of services delivered remotely, structured according to a complexity gradient, aimed to cover diagnostic procedures and monitor disease progression in chronic pediatric patients.

Methods
A multidisciplinary and multiprofessional project team was recruited, in collaboration with patients’ associations, to map a panel of available Evidence-Based solutions and address individual needs in full respect of the concept of personalized medicine. The solutions include a number of services from videoconsultations to more structure videotraining sessions.

Results
A modular framework made up of four three Macro-levels of complexity - Contactless Basic, Intermediate and Advanced - was displayed as an incremental set of services and operational planning establishing each phase, from factors influencing eligibility to the delivery of the most accurate and complex levels of care.

Conclusion
The multimodal, multidisciplinary ‘Contactless’ model allowed the inclusion of all Units of our Pediatric Department and families with children with disability or complex chronic conditions. The strengths of this project rely on its replicability outside of pediatrics and in the limited resources needed to practically impact patients, caregivers and professionals involved in the process of care. Its implementation in the future may contribute to reduce the duration of hospital admissions, money and parental absence from work.
A floppy infant without lingual frenulum and kyphoscoliosis: Ehlers Danlos syndrome case report
Authors: Conti Rosaura , Zanchi Chiara , Barbi Egidio 
Published: February 2021

Abstract
Background
Ehlers-Danlos syndrome (EDS) represents a group of connective tissue disorders characterized by the fragility of the soft connective tissues resulting in widespread skin, ligament, joint, blood vessel and internal organ involvement. The clinical spectrum is highly variable in terms of clinical features, complications, severity, biochemical characteristics and genes mutations.
The kyphoscoliotic type EDS (EDS VIA) is a rare variant of the disease, with an incidence of 1:100.000 live births. EDS VIA presents at birth as severe muscular hypotonia, early onset of progressive kyphoscoliosis, marked hyperelasticity and fragility of the skin with abnormal scarring, severe joint hypermobility, luxations and osteopenia without a tendency to fractures. This condition is due to a mutation in the PLOD1 gene, and less commonly in FKBP14 gene, which results in the erroneous development of collagen molecules with consequent mechanical instability of the affected tissue.

Case presentation
A female newborn, found to be floppy at birth, presented a remarkable physical examination for joint hypermobility, muscle weakness, hyperelastic skin, a slight curve of the spine, the absence of the inferior labial and lingual frenulum. Due to severe hypotonia, neuromuscular disorders such as Spinal Muscular Atrophy (SMA), genetic diseases such as Prader Willi syndrome (PWS), myopathies and connective tissue disorders were considered in the differential diagnosis. Targeted gene sequencing were performed for SMN1, PLOD1, FKBP14, COL6A1, COL6A2, COL6A3. The urinary lysyl and hydroxy-lysyl pyridinoline ratio was diagnostic before discovering the homozygous duplication in the PLOD1 gene, which confirmed kyphoscoliotic EDS diagnosis.

Conclusion
In front of a floppy infant, a large variety of disorders should be considered, including some connective diseases. The presence at the birth of kyphoscoliosis, associated with joint hypermobility and the absence of the lingual and lower lip frenulum, should suggest an EDS.
Alpha-enolase (ENO1), identified as an antigen to monoclonal antibody 12C7, promotes the self-renewal and malignant phenotype of lung cancer stem cells by AMPK/mTOR pathway
Authors: Shu Xiong , Cao Kai-Yue , Liu Hui-Qi , Yu Long , Sun Li-Xin , Yang Zhi-Hua , Wu Cheng-Ai , Ran Yu-Liang 
Published: February 2021

Abstract
Background
Tumor-associated antigens (TAAs) can be targeted in cancer therapy. We previously identified a monoclonal antibody (mAb) 12C7, which presented anti-tumor activity in lung cancer stem cells (LCSCs). Here, we aimed to identify the target antigen for 12C7 and confirm its role in LCSCs.

Methods
Immunofluorescence was used for antigen localization. After targeted antigen purification by electrophoresis and immunoblot, the antigen was identified by LC-MALDI-TOF/TOF mass spectrometry, immunofluorescence, and immunoprecipitation. The overexpression or silence of ENO1 was induced by lentiviral transduction. Self-renewal, growth, and invasion of LCSCs were evaluated by sphere formation, colony formation, and invasion assay, respectively. High-throughput transcriptome sequencing (RNA-seq) and bioinformatics analysis were performed to analyze downstream targets and pathways of targeted antigen.

Results
Targeted antigen showed a surface antigen expression pattern, and the 43–55 kDa protein band was identified as α-enolase (ENO1). Self-renewal, growth, and invasion abilities of LCSCs were remarkably inhibited by ENO1 downregulation, while enhanced by ENO1 upregulation. RNA-seq and bioinformatics analysis eventually screened 4 self-renewal-related and 6 invasion-related differentially expressed genes. GSEA analysis and qRT-PCR verified that ENO1 regulated self-renewal, invasion-related genes, and pathways. KEGG pathway analysis and immunoblot demonstrated that ENO1 inactivated AMPK pathway and activated mTOR pathway in LCSCs.

Conclusions
ENO1 is identified as a targeted antigen of mAb 12C7 and plays a pivotal role in facilitating self-renewal, growth, and invasion of LCSCs. These findings provide a potent therapeutic target for the stem cell therapy for lung cancer and have potential to improve the anti-tumor activity of 12C7.

Abstract
Background
Mesenchymal stromal cells (MSCs) constitute one of the cell types most frequently used in cell therapy. Although several studies have shown the efficacy of these cells to modulate inflammation in different animal models, the results obtained in human clinical trials have been more modest. Here, we aimed at improving the therapeutic properties of MSCs by inducing a transient expression of two molecules that could enhance two different properties of these cells. With the purpose of improving MSC migration towards inflamed sites, we induced a transient expression of the C-X-C chemokine receptor type 4 (CXCR4). Additionally, to augment the anti-inflammatory properties of MSCs, a transient expression of the anti-inflammatory cytokine, interleukin 10 (IL10), was also induced.

Methods
Human adipose tissue-derived MSCs were transfected with messenger RNAs carrying the codon-optimized versions of CXCR4 and/or IL10. mRNA-transfected MSCs were then studied, first to evaluate whether the characteristic phenotype of MSCs was modified. Additionally, in vitro and also in vivo studies in an LPS-induced inflamed pad model were conducted to evaluate the impact associated to the transient expression of CXCR4 and/or IL10 in MSCs.

Results
Transfection of MSCs with CXCR4 and/or IL10 mRNAs induced a transient expression of these molecules without modifying the characteristic phenotype of MSCs. In vitro studies then revealed that the ectopic expression of CXCR4 significantly enhanced the migration of MSCs towards SDF-1, while an increased immunosuppression was associated with the ectopic expression of IL10. Finally, in vivo experiments showed that the co-expression of CXCR4 and IL10 increased the homing of MSCs into inflamed pads and induced an enhanced anti-inflammatory effect, compared to wild-type MSCs.

Conclusions
Our results demonstrate that the transient co-expression of CXCR4 and IL10 enhances the therapeutic potential of MSCs in a local inflammation mouse model, suggesting that these mRNA-modified cells may constitute a new step in the development of more efficient cell therapies for the treatment of inflammatory diseases.
Systematic review on use, cost and clinical efficacy of automated decontamination devices
Authors: Dancer Stephanie J. , King Marco-Felipe 
Published: February 2021

Abstract
Background
More evidence is emerging on the role of surface decontamination for reducing hospital-acquired infection (HAI). Timely and adequate removal of environmental pathogens leads to measurable clinical benefit in both routine and outbreak situations.

Objectives
This systematic review aimed to evaluate published studies describing the effect of automated technologies delivering hydrogen peroxide (H202) or ultra-violet (UV) light on HAI rates.

Methods
A systematic review was performed using relevant search terms. Databases were scanned from January 2005 to March 2020 for studies reporting clinical outcome after use of automated devices on healthcare surfaces. Information collected included device type, overall findings; hospital and ward data; study location, length and size; antimicrobial consumption; domestic monitoring; and infection control interventions. Study sponsorship and duplicate publications were also noted.

Results
While there are clear benefits from non-touch devices in vitro, we found insufficient objective assessment of patient outcome due to the before-and-after nature of 36 of 43 (84%) studies. Of 43 studies, 20 (47%) used hydrogen peroxide (14 for outbreaks) and 23 (53%) used UV technology (none for outbreaks). The most popular pathogen targeted, either alone or in combination with others, was Clostridium difficile (27 of 43 studies: 63%), followed by methicillin-resistant Staphylococcus aureus (MRSA) (16 of 43: 37%). Many owed funding and/or personnel to industry sponsorship (28 of 43: 65%) and most were confounded by concurrent infection control, antimicrobial stewardship and/or cleaning audit initiatives. Few contained data on device costs and rarely on comparable costs (1 of 43: 2%). There were expected relationships between the country hosting the study and location of device companies. None mentioned the potential for environmental damage, including effects on microbial survivors.

Conclusion
There were mixed results for patient benefit from this review of automated devices using H202 or UV for surface decontamination. Most non-outbreak studies lacked an appropriate control group and were potentially compromised by industry sponsorship. Concern over HAI encourages delivery of powerful disinfectants for eliminating pathogens without appreciating toxicity or cost benefit. Routine use of these devices requires justification from standardized and controlled studies to understand how best to manage contaminated healthcare environments.
The relationship between political affiliation and beliefs about sources of “fake news”
Authors: Michael Robert B. , Breaux Brooke O. 
Published: February 2021

AbstractThe 2016 US Presidential campaign saw an explosion in popularity for the term “fake news.” This phenomenon raises interesting questions: Which news sources do people believe are fake, and what do people think “fake news” means? One possibility is that beliefs about the news reflect a bias to disbelieve information that conflicts with existing beliefs and desires. If so, then news sources people consider “fake” might differ according to political affiliation. To test this idea, we asked people to tell us what “fake news” means, and to rate several news sources for the extent to which each provides real news, fake news, and propaganda. We found that political affiliation influenced people’s descriptions and their beliefs about which news sources are “fake.” These results have implications for people’s interpretations of news information and for the extent to which people can be misled by factually incorrect journalism.
Approaches in cooling of resistive coil-based low-field Magnetic Resonance Imaging (MRI) systems for application in low resource settings

Published: February 2021

AbstractMagnetic Resonance Imaging (MRI), a non-invasive method for the diagnosis of diverse health conditions has experienced growing popularity over other imaging modalities like ultrasound and Computer Tomography. Initially, proof-of-concept and earlier MRI systems were based on resistive and permanent magnet technology. However, superconducting magnets have long held monopoly of the market for MRI systems with their high-field (HF) strength capability, although they present high construction, installation, and siting requirements. Such stringent prerequisites restrict their availability and use in low-middle income countries. Resistive coil-based magnet, albeit low-field (LF) in capacity, represent a plausible boost for the availability and use of MRI systems in resource constrained settings. These systems are characterized by low costs coupled with substantial image quality for diagnosis of some conditions such as hydrocephalus common is such regions. However, the nature of resistive coils causes them to heat up during operation, thus necessitating a dedicated cooling system to improve image quality and enhance system longevity. This paper explores a range of cooling methods as have been applied to resistive magnets, citing their pros and cons and areas for improvement.

Published: February 2021

PURPOSE: Drug therapy for cancer is a high-risk, high-volume clinical intervention that requires interprofessional teams. Given the complexity of anticancer drug therapy and safety concerns, an interdisciplinary team developed a novel training program for oncology registered nurses and pharmacists to improve cancer drug safety. METHODS: Participants completed preworkshop learning assessments and received access to web-based modules on six topics: hazardous drug handling, drug extravasation, hypersensitivity reaction management, sepsis recognition, immune checkpoint inhibitor toxicities, and oral oncolytic adherence. In a 7-hour workshop, participants applied module content in interactive exercises and high-fidelity simulations. Preworkshop and postworkshop questionnaires assessed changes in knowledge and confidence in each topic. Program satisfaction and changes to clinical practice or policies were assessed 3 months after the workshop. RESULTS: Two hundred ninety-two nurses and 82 pharmacists applied to participate, and 103 (35%) and 44 (54%) have participated, respectively. Long-term follow-up data were available on 133 (90%) participants. Change scores in confidence to meet program objectives increased between pre- and postworkshop (range of increase 0.6-0.8, P < .01). Knowledge scores increased significantly between pre- and postworkshop (average improvement of 3.2 points, P < .01). Overall program satisfaction was high (mean 5.0, standard deviation [0.2] on a five-point scale). Seventy-seven (60%) reported that they had made at least one clinical practice or institutional policy change at 3 months. CONCLUSION: An interprofessional education program with online modules, in-person interactive sessions, and simulation activities is a promising strategy to deliver cancer drug safety content to practicing oncology clinicians.

Published: February 2021

Abstract
Salt cavern redox flow batteries with a large salt-cavern storing electrolyte are a promising large-scale energy storage technology. Here a low-cost iron/organic redox material system was proposed to explore salt cavern redox flow batteries. To avoid the formation of ferric hydroxide, ligand threonine was used to enhance the stability of the ferric ion in aqueous solution. Paired with a two electron viologen catholyte and saturated brine solution as supporting electrolyte, the battery delivered a high battery efficiency and cycling stability, 99% CE, 80% EE, and an average 99.5% capacity retention per cycle. The impressive battery performance provides a promising strategy for developing large-scale salt-cavern redox flow batteries.

Published: February 2021

AimsSurgery is often indicated in patients with metastatic bone disease (MBD) to improve pain and maximize function. Few studies are available which report on clinically meaningful outcomes such as quality of life, function, and pain relief after surgery for MBD. This is the published protocol for the Bone Metastasis Audit — Patient Reported Outcomes (BoMA-PRO) multicentre MBD study. The primary objective is to ascertain patient-reported quality of life at three to 24 months post-surgery for MBD.MethodsThis will be a prospective, longitudinal study across six UK orthopaedic centres powered to identify the influence of ten patient variables on quality of life at three months after surgery for MBD. Adult patients managed for bone metastases will be screened by their treating consultant and posted out participant materials. If they opt in to participate, they will receive questionnaire packs at regular intervals from three to 24 months post-surgery and their electronic records will be screened until death or five years from recruitment. The primary outcome is quality of life as measured by the European Organisation for Research and the Treatment of Cancer Quality of Life questionnaire (EORTC-QLQ) C30 questionnaire. The protocol has been approved by the Newcastle & North Tyneside 2 Research Ethics Committee (REC ref 19/NE/0303) and the study is funded by the Royal College of Physicians and Surgeons of Glasgow (RCPSG) and the Association for Cancer Surgery (BASO-ACS).DiscussionThis will be the first powered study internationally to investigate patient-reported outcomes after orthopaedic treatment for bone metastases. We will assess quality of life, function, and pain relief at three to 24 months post-surgery and identify which patient variables are significantly associated with a good outcome after MBD treatment.

PurposeThis study aimed to determine the survival outcome and prognostic factors of patients with nasopharyngeal cancer accessing treatment in Yogyakarta, Indonesia.MethodsData on 759 patients with NPC diagnosed from 2007 to 2016 at Dr Sardjito General Hospital were included. Potential prognostic variables included sociodemographic, clinicopathology and treatment parameters. Multivariable analyses were implemented using semi-parametric Cox proportional hazards modelling and fully parametric survival analysis.ResultsThe median time of observation was 14.39 months. In the whole cohort the median observed survival was 31.08 months. In the univariable analysis, age, education status, insurance type, BMI, ECOG index, stage and treatment strategy had an impact on overall survival (OS) (p values <0.01). Semi-parametric multivariable analyses with stage stratification showed that education status, ECOG index, and treatment modality were independent prognostic factors for OS (p values <0.05). In the fully parametric models age, education status, ECOG index, stage, and treatment modality were independent prognostic factors for OS (p values <0.05). For both multivariable analyses, all treatment strategies were associated with a reduced hazard (semi-parametric models, p values <0.05) and a better OS (parametric models, p values <0.05) compared with no treatment. Furthermore, compared with radiation alone or chemotherapy alone, a combination of chemotherapy and radiation either in a form of concurrent chemoradiotherapy (CCRT), sequential chemotherapy and radiation, or induction chemotherapy followed by CCRT demonstrated a reduced hazard (hazard ratio/HR 0.226, 95% confidence interval/CI 0.089–0.363, and HR 0.390, 95%CI 0.260–0.519) and a better OS (time ratio/TR 3.108, 95%CI 1.274–4.942 and TR 2.531, 95%CI 1.829–3.233) (p values < 0.01).ConclusionsMedian OS for the cohort was low compared to those reported in both endemic and non-endemic regions. By combining the findings of multivariable analyses, we showed that age, education status, ECOG index, stage and first treatment modality were independent predictors for the OS.
