Published: March 2020

Abstract
Genome-resolved metagenomic sequencing approaches have led to a substantial increase in the recognized diversity of microorganisms; this included the discovery of novel metabolic pathways in previously recognized clades, and has enabled a more accurate determination of the extant distribution of key metabolisms and how they evolved over Earth history. Here, we present metagenome-assembled genomes of members of the Chloroflexota (formerly Chloroflexi or Green Nonsulfur Bacteria) order Aggregatilineales (formerly SBR1031 or Thermofonsia) discovered from sequencing of thick and expansive microbial mats present in an intertidal lagoon on Little Ambergris Cay in the Turks and Caicos Islands. These taxa included multiple new lineages of Type 2 reaction center-containing phototrophs that were not closely related to previously described phototrophic Chloroflexota—revealing a rich and intricate history of horizontal gene transfer and the evolution of phototrophy and other core metabolic pathways within this widespread phylum.

Abstract
Objective : In Ethiopia simulation-based anesthesia education is a new way of teaching method which started in Mekelle University as of January, 2019. Hence, the purpose of this study is to evaluate whether simulation-based training improves non-physician anesthetists’ knowledge and attitude on maternal and neonatal anesthesia cares or not.
Results : Out of 50 study subjects, 66% had a working experience of less than 5 years.. Knowledge score improved significantly from 49.78% and 66.22% in pretest and posttest results respectively. The posttest result was significantly improved (P< 0.001) for all knowledge questions. The respondents were asked about a negative statement and a positive statement about the need to have effective closed lope communication, maternal resuscitation and neonatal resuscitation. The attitude score improved from 72.45% to 79.11% in pretest and posttest respectively. From the 9 questions the attitudinal mean score for pretest was 6.52 and posttest 7.12. The null hypothesis of equal knowledge and attitude was rejected, t (49) = -5.54, p < 0.001 and t (49) = -2.25, p < 0.03 respectively.

Abstract
Background: Therapies that significantly improve the neurological and functional recovery of individuals with spinal cord injury (SCI) are still urgently needed. The ketogenic diet (KD) has been shown to improve forelimb motor function in a SCI rat model, likely by reducing inflammation and cell death in the spinal cord. Furthermore, our recent pilot study in patients with SCI showed that, compared with a standard hospital diet (SD), 5 weeks of KD started during acute care, improved upper extremity motor function, and reduced serum levels of a neuroinflammatory blood protein. The primary goals of the current study are to: 1) show the safety and feasibility of administering a KD during acute care for SCI; 2) determine if consuming 5 weeks of a KD significantly improves motor and sensory functions, functional independence, and glycemic control; and 3) quantify serum biomarkers that are linked to improvements in neurological recovery and functional independence via targeted proteomics.
Methods/Design: In a single-masked, longitudinal, randomized parallel controlled study, a total of 60 eligible participants ranging in age from 18 to 60 years with acute traumatic SCI (cervical 5 – thoracic 12) American Spinal Injury Association impairment scale (AIS A-C): AIS-A, sensorimotor complete; AIS-B, sensory incomplete/motor complete; and AIS-C, non-functional motor incomplete, are being enrolled. Neurological and functional examinations, resting energy expenditure, blood, urine, and stool collections, and protein analyses related to neurological recovery will be performed within 72 h of injury (baseline measure) and repeated after 5 weeks of KD or SD (discharge measure). We anticipate a completion rate of 80% with a total of 48 participants.
Discussion: Intervention with a more neuroprotective diet during acute care of SCI can be implemented anywhere in the world at low cost and without major regulatory hurdles. Better functional recovery will lead to a better quality of life and long-term health outcomes in individuals with SCI. While this study targets SCI, if successful it has the potential to improve neurological outcomes for individuals with various traumatic injuries.

Abstract
Background: Stem cells from different sources could differentiate into dopamine-producing cells and ameliorate behavioral deficits in Parkinsonian models. Especially, human bone marrow mesenchymal stem cells (hBMSCs) have many advantages without ethical dispute. Liver X receptor s (LXRs) are involved in the maintenance of the normal function of the central nervous system myelin. We have reported the induction of cocktail-induced da phenotypes from adult rat BMSCs by using sonic hedgehog (SHH), fibroblast growth factor 8 (FGF8), basic fibroblast growth factor (bFGF) and TO901317 (agonist of LXRs) with 87.42% of efficiency in 6 days of period of induction. But the previous work did not verify whether the induced cells had the corresponding neural function.
Methods: In this study, we demonstrated that TO901317 could promote the differentiation of hBMSCs into dopaminergic neurons. Neuronal markers (Tuj1, Neun and Nestin), dopamine neuron markers (tyrosine hydroxylase, TH), LXRa and LXRb were detected by immunofluorescence. RT-qPCR was used to measure the mRNA expressions of adenosine triphosphate-binding cassette transporter A1 (ABCA1). Western Blotting detected the changes of LXRa, LXRb and TH expression.
Results: TO901317 significantly enhanced the differentiation from hBMSCs to DA neurons. Only the LXR+GF group released dopamine by the result of enzyme linked immunosorbent assay (ELISA). Compared with the control group and GF group, the optimal time for differentiation of hBMSCs treated by 0.5mM TO901317 combined with GF was six days. And the maximum induction efficiency was 91.67%. After transplanting induced-cells into Parkinson's disease rats, the symptoms of Parkinson's rats decreased, and the number of dopamine neurons increased in the substantia nigra and striatum.
Conclusions: TO901317 promoted differentiation of hBMSCs into dopamine neurons may be related to activation of LXR-ABCA1 signaling pathway. These data suggest that TO901317 may serve as a potential therapeutic methods for Parkinson's disease.

Published: March 2020

Abstract
Background

Befriending is a popular form of volunteering in healthcare, and research suggests that it can be beneficial for people with mental illness. This study aimed to explore the experiences of a large sample of volunteer befrienders and patients who participated in the VOLUME trial, testing the efficacy of a structured befriending programme for individuals with psychosis. This is the first study to explore the specific challenges and benefits of befriending in both volunteers and patients in this population within the same programme.

Methods

A series of in-depth semi-structured interviews were conducted with 34 volunteer befrienders and 28 participating patients. All participants who had taken part in at least one befriending session were invited to be interviewed about their experiences with the aim of including a wide range of views, including those who were more or less engaged with the befriending programme. The data were analysed using Thematic Analysis.

Results

Four broad themes were developed from the analysis of the befriender and patient interviews which, although were largely discrete, captured the overall experiences of participating in the befriending programme: 1) Bridging the gap, 2) A genuine relationship that developed over time, 3) A big commitment, and 4) A flexible approach.

Conclusions

These results further support that, befriending programmes for individuals with psychosis can be a worthwhile experience for both befrienders and patients. However, participation also requires perseverance and flexibility from both sides. Different factors, such as incorporating participant preferences for frequency of meetings, have to be considered in the development and management of a befriending programme in order to provide effective support to both befrienders and patients.

Published: March 2020

Abstract
Background：Autoimmune hepatitis (AIH) is serious autoimmune liver diseases that threaten people’s health worldwide, emphasizing the need to identify novel treatment. Stem cells from human exfoliated deciduous teeth (SHED), which is easy to obtain and non-invasive, showed pronounced proliferation and immunomodulation capacity. This study aims to investigate the effect of SHED on ConA-induced AIH and the potential underlying mechanisms.Methods: We used a concanavalin A (ConA) induced acute hepatitis mouse model and in vitro co-culture system to study the protective effects of SHED on ConA-induced autoimmune hepatitis and the underlying mechanisms.Results: SHED infusion could prevent aberrant histopathological architecture of liver with infiltration of abundant of CD3+, CD4+, TNF-α+ and IFN-γ+ inflammatory cells induced by ConA. The expression of ALT and AST which indicated the liver function significantly elevated in hepatitis mice. While SHED infusion could block the elevation of ALT and AST induced by ConA. Mechanistically, Con-A upregulated TNF-α and IFN-γ expression activated NF-κB pathways to induced hepatocyte apoptosis, resulting in acute liver injury. SHED administration protected hepatocytes from Con-A-induced apoptosis. Conclusions: These results demonstrated that SHED alleviated ConA-induced acute liver injury via inhibition of hepatocyte apoptosis mediated by the NF-κB pathways. Our findings could provide a potential prevention and therapeutic strategy for hepatitis and acute hepatic injury.

Published: March 2020

Abstract
Background In Microbiome data analysis, unsupervised clustering is often used to identify naturally occurring clusters, which can then be assessed for associations with characteristics of interest. In this work, we systematically compared beta diversity and clustering methods commonly used in microbiome analyses. We applied these to four published datasets where highly distinct microbiome profiles could be seen between sample groups. Results Although no single method outperformed the others consistently, we did identify key scenarios where certain methods can underperform. Specifically, the Bray Curtis metric resulted in poor clustering in a dataset where high-abundance OTUs were relatively rare. In contrast, the unweighted UniFrac metric clustered poorly when used on a dataset with a high prevalence of low-abundance OTUs. To test our proposition, we systematically modified properties of the poorly performing datasets and found that this approach resulted in improved Bray Curtis and unweighted UniFrac performance. Conclusions Based on these observations, we rationally combined the Bray Curtis metric and the unweighted UniFrac metrics and found that this new beta diversity metric showed high performance across all datasets.

Abstract
Background: Frankliniella occidentalis (Thysanoptera: Thripidae) is a highly destructive sucking pest of numerous crops. The entomogenous fungi of Lecanicillium spp. are important pathogens of insect pests, and some have been developed as commercial biopesticides. In order to explore the wild resources of Lecanicillium spp. in the development of more effective F. occidentalis controls, efficient gene combinations for strain identification were screened from internal transcribed spacer (ITS) and the genes SSU, LSU, TEF, RPB1, and RPB2.Results: In this study, six genes were used to reconstruct the phylogeny of Lecanicillium genus respectively. Among these, only four events (ITS, TEF, RPB1, RPB2) were validated using the gold standard for identifying the strains. All the phylogenetic trees reconstruct by free combination of these four events exhibited the same topology. Bioassay studies of a purified conidial suspension further confirmed the infection of second-instar nymphs and adult female F. occidentalis by seven strains of Lecanicillium. L. attenuatum strains GZUIFR-lun1405 was the most virulent, approximately 8.33% of adult and 23.33% of nymphs F. occidentalis survived after a 7-d exposure. Two strains were selected to compare the effects on the amount of eggs laid by F. occidentalis. The number of nymphs of F. occidentalis significantly decreased when adult F. occidentalis were treated with L. cauligalbarum strain GZUIFR-ZHJ01 compared to the controls.Conclusions: We found that combination of ITS and TEF could be used for fast recognition of Lecanicillium spp. We demonstrated that L. attenuatum, L. cauligalbarum, L araneogenum, and L. aphanocladii had various efficacies against F. occidentalis which were the first to demonstrate efficient control of F. occidentalis. In addition, the L. cauligalbarum strain GZUIFR-ZHJ01 not only caused high mortality in F. occidentalis but also inhibited the fecundity of the pest.

Abstract
Background: Residential aged care facility residents experience high rates of hospital admissions which are stressful, costly and often preventable. The EDDIE program is a hospital avoidance initiative designed to enable nursing and care staff to detect, refer and quickly respond to early signals of a deteriorating resident. The program was implemented in a 96-bed residential aged care facility in regional Australia.Methods: A prospective pre-post cohort study design was used to collect data on costs of program delivery, hospital admission rates and length of stay for the 12 months prior to, and following, the intervention. A Markov decision model was developed to synthesize study data with published literature in order to estimate the cost-effectiveness of the program. Quality adjusted life years (QALYs) were adopted as the measure of effectiveness.Results: The EDDIE program was associated with a 19% reduction in annual hospital admissions and a 31% reduction in the average length of stay. The cost-effectiveness analysis found the program to be both more effective and less costly than usual care, with 0.06 QALYs gained and $249,000 health system costs saved in a modelled cohort of 96 residents. A probabilistic sensitivity analysis estimated that there was an 86% probability that the program was cost-effective after taking the uncertainty of the model inputs into account. Conclusions: This study provides promising evidence for the effectiveness and cost-effectiveness of a nurse led, early intervention program in preventing unnecessary hospital admissions within a residential aged care facility. Further research in multi-site randomised studies is needed to confirm these results.

Published: March 2020

Abstract
Background: Arthroscopic shoulder surgery tends to cause a drop in blood pressure due to the beach chair position used during the procedure, including activation of the Bezold-Jarisch reflex. We hypothesized that patients with low blood pressure undergoing arthroscopic shoulder surgery in the beach chair position would also have reduced renal function after surgery.Methods: The medical records of patients (N = 643) undergoing arthroscopic shoulder surgery in the beach chair position between July 2013 and May 2015 were examined. The vital signs were measured at 5-minute intervals, and the number of non-invasive blood pressure (NIBP) measurements in the upper arm dropping below a mean arterial pressure (MAP) of 50 mmHg (MAP50) or 60 mmHg (MAP60) were recorded. The primary outcome was change in creatinine immediately after surgery relative to the preoperative level (Cr post/pre). The factors affecting Cr post/pre were examined by correlation analysis.Results: A total of 597 patients were included in the analysis. Longer duration of hypotension during surgery (MAP50) was correlated with higher Cr post/pre (R = 0.107, P = 0.010). However, the correlation between MAP60 and Cr post/pre was not significant (R = 0.033, P = 0.431).Conclusions: It is necessary to ensure that the MAP does not fall below 50 mmHg to ensure sufficient renal function during general anesthesia for shoulder arthroscopy in a beach chair position.

Abstract
Background The lung is very easily injured by primary shock wave in recent military conflicts. While it is not very clear for its mechanisms. Protein markers can provide new ideas for diagnosis and treatment. Methods A quantitative analysis of their global proteome was conducted in lung from mice with blast injury using LC-MS/MS. Protein annotation, unsupervised hierarchical clustering, functional classification, functional enrichment and cluster, and protein-protein interaction analyses were performed. Furthermore, western blotting was used to verify the differential protein. Results A total of 6498 proteins were identified, of which 5520 proteins were quantified. The fold-change cutoff was set at 1.2; 132 proteins were upregulated, and 104 proteins were downregulated. The bioinformatics analysis indicated that the differentially expressed proteins were involved in the cholesterol metabolism, asthma, non-alcoholic fatty liver disease and so on. Remarkably, the processe related to the change of oxidative phosphorylation including the NADH dehydrogenase, Cytochrome C reductase, Cytochrome C oxidase and F-type ATPase were significantly upregulated, which were further verified by western blotting. Conclusion These results confirmed that the oxidative phosphorylation is critical to blast-induced lung injury. LC/MS-based profiling presented candidate target/pathways that could be explored for future therapeutic development.

Abstract
Background The risk of colorectal cancer (CRC) development has been related to telomere dysfunction and obesity. However, prognosis of patients affected by CRC has not clearly established considering both telomere attrition and obesity status. Previous published data highlights the importance of studying how obesity influences telomere function and its potential role as a predictor of prognosis in CRC. The aim of this study was to evaluate the impact of obesity and telomere status in the prognosis of patients affected by CRC and submitted to curative surgical treatment. Methods We performed a prospective study including 162 CRC patients submitted to curative surgical treatment. Samples were obtained from tumor and non-tumor tissues. Subjects were classified according to their Body Mass Index (BMI). Telomere status was established through telomere length and telomerase evaluation. Statistical analyses were performed using the SPSS software package version 22. Differences in two or more groups of study were calculated by parametric or non-parametric tests, depending on normality and homoscedasticity conditions of the variables. Prognosis was analyzed using the Kaplan-Meier method. The potential prognostic impact of the variables considered in this work jointly, was evaluated by Cox multivariate regression analyses. Results Patients with shorter telomeres, both in the tumor (median telomere length < 6.5 kb) and their non-tumor paired tissues (median telomere length < 7.1 kb), had the best clinical evolution, independently of the Dukes' stage of cancers (P = 0.025, for tumor samples; P = 0.003, for non-tumor samples). Telomere shortening was inversely associated with BMI in CRC patients. Also, subjects with a BMI > 31.85kg/m 2 showed the worse clinical outcomes. Of interest, the impact of BMI showed gender dependence, since only the group of men showed significant differences in CRC prognosis in relation to obesity status (P = 0.037). Conclusions Telomere length constitutes a useful biomarker to predict prognosis in CRC. Independently of BMI values, the better clinical evolution was associated with shorter telomeres. Obesity seems to have an impact on the clinical outcomes of CRC; however, the impact of BMI seems to be related to other factors such as gender.
