Abstract
Background: Childbirth preparation classes can reduce pregnant women’s anxiety and fear for their childbirth. However, to evaluate women’s feedback and their satisfaction with these classes, there is a need for a standard instrument that is suitable for Iranian context. This study is aimed to translate and conduct a psychometric analysis of the Satisfaction with the Childbirth Education Class Questionnaire (SCECQ) for Iranian population. Methods: The questionnaire was translated from English into Persian through the forward-backward translation method. The cluster sampling method was employed to select 205 pregnant women with gestational age of 35-37 weeks from all health complexes of Tabriz, Iran. The face, content, and construct validity of the research instrument were assessed through exploratory and confirmatory factor analyses. Internal consistency and test-retest reliability were measured to evaluate the overall reliability of the questionnaire.Results: The impact scores of all items were above 1.5. The content validity index (CVI) and content validity ratio (CVR) of the questionnaire were 0.88 and 0.94, respectively. The convergent construct validity of the whole questionnaire and those of its three subscales were confirmed through the exploratory factor analysis (EFA). The factor loadings of no items were below 0.3, and the X2⁄df ratio was smaller than 5. The overall model validity was confirmed by having the Root Mean Square Error of Approximation (RMSEA) smaller than 0.08. Cronbach’s alpha and intraclass correlation coefficient (ICC) were 0.93 and 0.96, respectively, indicating the acceptable reliability of the questionnaire.Conclusion: The Persian version of this questionnaire, entitled SCECQ is a valid and reliable instrument for measuring Iranian women’s satisfaction with childbirth education classes.

Abstract
Background: Stevia rebaudiana (Bertoni) is considered one of the most valuable plants because of the steviol glycosides (SGs) that can be extracted from its leaves. Glycosyltransferases (GTs), which can transfer sugar moieties from activated sugar donors onto saccharide and nonsaccharide acceptors, are widely distributed in the genome of S. rebaudiana and play important roles in the synthesis of steviol glycosides. Results: Six stevia genotypes with significantly different concentrations of SGs were obtained by induction through various mutagenic methods, and the contents of seven glycosides (stevioboside, Reb B, ST, Reb A, Reb F, Reb D and Reb M) in their leaves were considerably different. Then, NGS and single-molecule real-time (SMRT) sequencing were combined to analyse leaf tissue from these six different genotypes to generate a full-length transcriptome of S. rebaudiana. Two phylogenetic trees of glycosyltransferases (SrUGTs) were constructed by the neighbour-joining method and successfully predicted the functions of SrUGTs involved in SG biosynthesis. With further insight into glycosyltransferases (SrUGTs) involved in SG biosynthesis, the weighted gene co-expression network analysis (WGCNA) method was used to characterize the relationships between SrUGTs and SGs, and forty-four potential SrUGTs were finally obtained, including SrUGT85C2, SrUGT74G1, SrUGT76G1 and SrUGT91D2, which have already been reported to be involved in the glucosylation of steviol glycosides, illustrating the reliability of our results.Conclusion: Combined with the results obtained by previous studies and those of this work, we systematically characterized glycosyltransferases in S. rebaudiana and forty-four candidate SrUGTs involved in the glycosylation of steviol glucosides were obtained. Moreover, the full-length transcriptome obtained in this study will provide valuable support for further research investigating S. rebaudiana.

Abstract
Back ground: Ventilator-associated pneumonia (VAP) is a common nocosomial infection in intensive care unit (ICU). Local microbiological surveillance of pathogens and resistance patterns for early-onset VAP (EOVAP) and late-onset VAP (LOVAP) will help to choose appropriate empiric antibiotics. Objective: To compare the multi-drug resistant (MDR) pathogens, treatment outcomes, and factors associated with hospital mortality of VAP. Method: A cross-sectional study between 1 January 2015 and 31 December 2017 at Srinagarind hospital, Khon Kaen University was conducted. The demographic data, causative pathogens, hospital length of stay (LOS), ICU LOS, mechanical ventilator (MV) days, and hospital mortality were retrospectively reviewed. Results: One hundred and ninety patients were enrolled; 42 (22%) were EOVAP and 148 (78%) were LOVAP. Acinetobacter baummanii was the most common pathogen in both groups (50 % EOVAP vs 52.7% LOVAP). MDR pathogens were significant greater in LOVAP (81.8 %) than EOVAP (61.9%) (p = 0.007). The EOVAP had a significantly better ICU LOS (median 20.0 (11.0, 30.0) vs. 26.5 (17.0, 43.0) days), hospital LOS (median 26.5 (15.0, 44.0) vs. 35.5 (24.0, 56.0) days) shorter MV days (14.0 (10.0, 29.0) vs. 23.0 (14.0, 35.5) days) and lower hospital mortality (11.9 % VS 27.7%) than LOVAP ( p < 0.05). The factor associated with hospital mortality was having simplified acute physiology score (SAP) ≥ 40 with an adjusted odds ratio (aOR) of 2.22 (95%CI, 1.08-4.54, p = 0.02). Conclusion: LOVAP had significantly higher MDR pathogens, MV days, ICU LOS, hospital LOS and hospital mortality than EOVAP. A broad-spectrum antibiotic to cover MDR pathogens should be considered in LOVAP. The factor associated with hospital mortality of VAP was a SAPII score ≥ 40.

Abstract
Introduction: There is a large incidence of shoulder instability among active young athletes and military personnel. Shoulder stabilization surgery is the commonly employed intervention for treating individuals with instability. Following surgery, a substantial proportion of individuals experience acute post-operative pain, which is usually managed with opioid pain medications. Unfortunately, the extended use of opioid medications can have adverse effects that impair function and reduce military operational readiness, but there are currently few alternatives. However, Battlefield Acupuncture (BFA) is a minimally invasive therapy demonstrating promise as a non-pharmaceutical intervention for managing acute post-operative pain.Methods: This is a parallel, two-arm, single-blind randomized clinical trial. The two independent variables are intervention (2 levels; standard physical therapy and standard physical therapy plus Battlefield Acupuncture) and time (5 levels; 24-hours, 48-hours, 72-hours, 1-week, and 4-weeks post shoulder stabilization surgery). The primary dependent variables is worst and average pain as measured on the Visual Analog Scale. Secondary outcomes include medication usage, Profile of Mood States, and Global Rating of Change.Discussion: The magnitude of the effect of BFA is uncertain; current studies report confidence intervals of between group differences that include minimal clinically important differences between intervention and control groups. The results of this study may help determine if BFA is an effective adjunct to physical therapy in reducing pain and opioid usage in acute pain conditions.

Abstract
Background: Genome-wide association studies (GWAS) have been utilized to detect genetic variations related to the powdery mildew (PM) resistance and several agronomic traits in common bean. However, its application in common bean and the PM interactions to identify genes and their location in the common bean genome has not been fully addressed.Results: Genome-wide association studies (GWAS) through marker-trait association are useful molecular tools for the identification of disease resistance and other agronomic traits. SNP genotyping with a BeadChip containing 5398 SNPs was used to detect genetic variations related to resistance to PM disease in a panel of 211 genotypes grown under field conditions for two consecutive years. Significant SNPs identified on chromosomes Pv04 and Pv10 were repeatable, confirming the reliability of the phenotypic data scored from the genotypes grown in two locations within two years. A cluster of resistance genes was revealed on the Pv04 of common bean genome among which CNL and TNL like resistance genes were identified. Furthermore, two resistance genes Phavu_010G1320001g and Phavu_010G136800g were also identified on Pv10; further sequence analysis showed that these genes were homologs to the Arabidopsis disease resistance protein (RLM1A-like) and the putative disease resistance protein (At4g11170.1), respectively. Two LRR receptor-like kinases (RLK) were also identified on Pv11 in samples collected in 2018 only. Many genes encoding auxin-responsive protein, TIFY10A protein, growth-regulating factor 5-like, ubiquitin-like protein, cell wall protein RBR3-like protein related to PM resistance were identified nearby significant SNPs. These results suggested that the resistance to PM pathogen involves a network of many genes constitutively co-expressed and may generate several layers of defense barriers or inducible reactions.Conclusion: Our results provide new insights into common bean and PM interactions, and revealed putative resistance genes as well as their location on common bean genome that could be used for marker-assisted selection, functional genomic study approaches to confirm the role of these putative genes; hence, developing common bean resistance lines to the PM disease.

Published: October 2020

Abstract
Background: To evaluate the accuracy and performance of the Autof MS1000 mass spectrometer in bacteria and yeast identification, 2,342 isolates were obtained from microbial cultures of clinical specimens (e.g. blood, cerebrospinal fluid, respiratory tract samples, lumbar puncture fluid, wound samples, stool, and urine) collected in 2019 in Henan Provincial People’s Hospital. Repetitive strains from the same patient were excluded. We tested the Autof MS1000 and Bruker Biotyper mass spectrometry systems and the classical biochemical identification system VITEK 2/API 20C AUX. Inconsistencies in strain identification among the three systems were identified by 16S rDNA and gene sequencing.Results: At the species level, the Autof MS1000 and Bruker Biotyper systems had isolate identification accuracies of 98.9% and 98.5%, respectively. At the genus level, the Autof MS1000 and Bruker Biotyper systems were 99.7% and 99.4% accurate, respectively. The instruments did not significantly differ in identification accuracy at either taxonomic level. The frequencies of unreliable identification were 1.1% (26/2,342) for the Autof MS1000 and 1.5% (34/2,342) for the Bruker Biotyper. In vitro experiments demonstrated that the coincidence rate of the Autof MS1000 mass spectrometer in the identification of five types of bacteria was >93%, the identification error rate was <3%, and the no identification rate was 0. This indicates that the Autof MS1000 system is acceptable for identification.Conclusions: The Autof MS1000 mass spectrometer can be utilised to identify clinical isolates. However, an upgradation of the database is recommended to correctly identify rare strains.

Abstract
Background Surgical treatment plays a key role in the cure of gastric cancer. Our aim was to analyze changes in epidemiology and outcome, over a time period of 15 years.Methods 410 patients operated between January 2004 and December 2018 were enrolled. Patients were subdivided into 3 groups. The entire cohort was evaluated, and a more detailed analysys was made in patients that underwent a curative surgery. Survival outcomes and oncological surgical outcomes have been described and correlated with Overall Survival.Results Results showed an increase trend in gastric cancer operation over the time period analyzed (p< 0.05). Overall and disease free survival did not vary in the different time periods. In patients treated with the intent to cure: 5- and 10-Year survivals were respectively: 44% and 34.7%; 5- and 10 years disease free survival were 50.7 and 49.4%. Type of lymphadenectomy and number of lymphondal harvested changed significantly over the time (p < 0.05). Conclusions Our result showed an increasing trend in number of surgery for gastric adenocarcinoma in our center, probably due to the increasing in absolute number of cases in Italy and worldwide. We have also show that tumor location is shifting towards a distal location in the last period. Moreover in the last period there is also an improving trend in overall survival, probably due to a more aggressive surgery adopted and also due to an improved learning curve. Gastric surgery must be done in an experienced center to obtain oncological outcomes; in selected cases an extended lymphadenectomy could give survival benefit to patients with locally advanced gastric cancer.

Abstract
Backgrounds: Aniso-astigmatism may hinder normal visual development in preschool children. Knowing its prevalence, biometric parameters and risk factors is fundamental to children eye care. The purpose of this study was to determine the biometric components of aniso-astigmatism and associated maternal risk factors in Chinese preschool children.Methods: In the population-based, prospective cohort Nanjing Eye Study, children were measured for noncycloplegic refractive error using an autorefractor and for biometric parameters using an optical low-coherent reflectometry. The difference of total astigmatism (TA) between both eyes was calculated using cylinder power (non-vectorial aniso-TA was defined as ≥1.00 Dioptre Cylinder [DC] between both eyes) and by vector analysis (vectorial aniso-TA was defined as a difference of ≥0.5 in J0 or J45 between both eyes which is equivalent to 1.00 DC). The prevalence of aniso-TA was presented. Interocular biometric parameters were compared between with vs. without aniso-astigmatism group. In addition, risk factors were determined using multivariate logistic regression model.Results: Of 1131 children (66.90±3.38 months, 53.31% male), the prevalence of non-vectorial aniso-TA was 1.95% (95% Confidence Interval (CI)=1.14%-2.75%), while the prevalence of vectorial aniso-TA was twice as common as non-vectorial aniso-TA, neither varying with sex or age. With aniso-TA eyes were more asymmetric in axial length and corneal curvature radius than without aniso-TA eyes. In multivariate logistic regression model, 5-min Apgar score less than 7 was significantly associated with higher risk of aniso-TA (vectorial aniso-TA: Odds Ratio (OR)=6.42, 95%CI=2.63-15.69, P<0.001; non-vectorial aniso-TA: OR=4.99, 95%CI=1.41-17.68, P=0.01）. Being twin or triple was significantly associated with higher risk of vectorial aniso-CA (OR=2.43, 95%CI=1.05-5.60, P=0.04). Pre-term delivery (OR=2.60, 95%CI=1.09-6.15, P=0.03) and post-term delivery (OR=3.61, 95%CI=1.31-9.96, P=0.01) were significantly associated with higher risk of vectorial aniso-CA.Conclusions: Both corneal curvature radius and axial length asymmetry were correlated with aniso-TA. Children with 5-min Apgar score<7 were more likely to have aniso-TA, while twin or triple, pre-term or post-term delivery were more likely to have vectorial aniso-CA.

Abstract
Introduction:Preliminary research has shown the effectiveness of supervised exercise-based interventions in alleviating sequela resulting from metastatic prostate cancer. Despite this, many individuals do not engage in sufficient exercise to gain the benefits. There are many barriers which limit the uptake of face-to-face exercise in this population including lack of suitable facilities, remoteness, access to experts, significant fatigue, urinary incontinence, and motivation. Technology-enabled interventions offer a distance-based alternative. This protocol describes a pilot two-armed randomised controlled study that will investigate the feasibility and preliminary efficacy of an online exercise and behavioural change tool (ExerciseGuide) among individuals with metastatic prostate cancer.Methods:Sixty-six participants with histologically diagnosed metastatic prostate cancer will be randomised into either the eight-week intervention or a wait-list control. The intervention arm will have access to a tailored website, remote supervision, and three tele-coaching sessions to enhance support and adherence. Algorithms will individually prescribe resistance and aerobic exercise based upon factors such as metastasis location, pain, fatigue, confidence, and current exercise levels. Behavioural change strategies and education on exercise benefits, safety and lifestyle are also tailored through the website. The primary outcome will be intervention feasibility (safety, usability, acceptability, adherence). Secondary exploratory outcomes include changes in physical activity, quality of life, sleep, and physical function. Outcomes will be measured at baseline and week 9.Discussion:The study aims to determine the potential feasibility of an online remotely-monitored exercise intervention developed for individuals with metastatic prostate cancer. If feasible, this pilot intervention will inform the design and implementation of further distance-based interventions.Trial registration: ANZCTR, ACTRN12614001268639.

Abstract
Background: Dysregulation of long non-coding RNAs (lncRNAs) is responsible for cancer initiation and development, positioning lncRNAs as not only biomarkers but also promising therapeutic targets for cancer treatment. A growing number of lncRNAs have been reported in hepatocellular carcinoma (HCC), but their functional and mechanistic roles remain unclear. Methods: Gene Set Enrichment Analysis was used to investigate the molecular mechanism of UPK1A antisense RNA 1 (UPK1A-AS1). Cell Counting Kit-8 assays, EdU assays, flow cytometry, western blotting, and xenograft assays were used to confirm the role of UPK1A-AS1 in the proliferation of HCC cells in vitro and in vivo . Bioinformatics analyses and quantitative polymerase chain reaction (qRT-PCR) were performed to explore the interplay between UPK1A-AS1 and enhancer of zeste homologue 2 (EZH2). RNA immunoprecipitation (RIP), RNA pull-down assays, western blotting, and qRT-PCR were conducted to confirm the interaction between UPK1A-AS1 and EZH2. The interaction between UPK1A-AS1 and miR-138-5p was examined by luciferase reporter and RIP assays. Finally, the expression level and prognosis value of UPK1A-AS1 in HCC were analyzed using RNA sequencing data from The Cancer Genome Atlas datasets. Results: We showed that UPK1A-AS1, a newly identified lncRNA, promoted cellular proliferation and tumor growth by accelerating cell cycle progression. Cell cycle-related genes, including CCND1, CDK2, CDK4, CCNB1, and CCNB2, were significantly upregulated in HCC cells overexpressing UPK1A-AS1. Furthermore, overexpression of UPK1A-AS1 could protect HCC cells from cis-platinum toxicity. Mechanistically, UPK1A-AS1 interacted with EZH2 to mediate its nuclear translocation and reinforce its binding to SUZ12, leading to increased H27K3 trimethylation. Targeting EZH2 with specific small interfering RNA impaired the UPK1A-AS1-mediated upregulation of proliferation and cell cycle progression-related genes. Moreover, miR-138-5p was identified as a direct target of UPK1A-AS1. Additionally, UPK1A-AS1 was significantly upregulated in HCC, and the upregulation of UPK1A-AS1 predicted poor prognosis for patients with HCC. Conclusions: Our study revealed that UPK1A-AS1 promotes HCC development by accelerating cell cycle progression through interaction with EZH2 and sponging of miR-138-5p, suggesting that UPK1A-AS1 possesses substantial potential as a novel biomarker for HCC prognosis and therapy.
