Abstract
Background: Antimicrobial resistance is a global public health concern, with extensive associated health and economic implications. Actions to slow and contain the development of resistance are imperative. Despite the fact that overuse and misuse of antibiotics are highlighted as major contributing factors to this resistance, no sufficiently validated measures aiming to investigate the drivers behind consumer behaviour amongst the general population are available. The objective of this study was to develop and investigate the psychometric properties of an original, novel and multiple-item questionnaire, informed by the Theory of Planned Behaviour, to measure factors contributing to self-reported antibiotic use within the community.

Method: A three-phase process was employed, including literature review and item generation; expert panel review; and pre-test. Investigation of the questionnaire was subsequently conducted through a cross-sectional, anonymous survey. Orthogonal principal analysis with varimax rotation, cronbach alpha and linear mixed-effects modelling analyses were conducted. A 60 item questionnaire was produced encompassing demographics, social desirability, three constructs of the Theory of Planned Behaviour including: attitudes and beliefs; subjective norm; perceived behavioural control; behaviour; and a covariate–knowledge.

Results: 373 participants completed the survey. 80 participants (21%) were excluded due to social desirability concerns, with data from the remaining 293 participants analysed. Results showed modest but acceptable levels of internal reliability, with high inter-item correlations within each construct. All four variables and the outcome variable of antibiotic use behaviour comprised four items with the exception of social norms, for which there were two items, producing a final 18 item questionnaire. Perceived behavioural control, social norms, the interaction between attitudes and beliefs and knowledge, and the presence of a healthcare worker in the family were all significant predictors of antibiotic use behaviour. All other predictors tested produced a nonsignificant relationship with the outcome variable of self-reported antibiotic use.

Conclusion: This study successfully developed and validated a novel tool which assesses factors influencing community antibiotic use and misuse. The questionnaire can be used to guide appropriate intervention strategies to reduce antibiotic misuse in the general population. Future research is required to assess the extent to which this tool can guide community-based intervention strategies.

Abstract
Background: Phosphorus (P) deficiency is one of the major constraints limiting plant growth, especially in acid soils. Stylosanthes (stylo) is a pioneer tropical legume with excellent adaptability to low P stress, but its underlying mechanisms remain largely unknown.
Results: In this study, the physiological, molecular and metabolic changes in stylo responding to phosphate (Pi) starvation were investigated. Under low P condition, the root growth in stylo was significantly enhanced, which was accompanied with up-regulation of expansin genes participating in cell wall loosening. Metabolic profiling analysis showed that a total of 256 metabolites with differential accumulation were identified in stylo roots responding to P deficiency, which mainly include flavonoids, sugars, nucleotides, amino acids, phenylpropanoids and phenylamides. P deficiency led to significant reduction in the accumulation of phosphorylated metabolites (e.g., P-containing sugars, nucleotides and cholines), suggesting that internal P utilization was enhanced in stylo roots. However, flavonoid metabolites, such as kaempferol, daidzein and their glycoside derivatives, were significantly increased in P-deficient stylo roots. Furthermore, the transcripts of various genes involved in flavonoids synthesis were found to be up-regulated by Pi starvation in stylo roots. In addition, the abundance of phenolic acids and phenylamides was significantly increased in stylo roots during P deficiency. The enhanced accumulation of the metabolites in stylo roots, such as flavonoids, phenolic acids and phenylamides, might facilitate P solubilization and cooperate with beneficial microorganisms in rhizosphere, and thus contributing to P acquisition and utilization in stylo.
Conclusions: These results suggest that stylo plants cope with P deficiency by modulating root morphology, scavenging internal Pi from phosphorylated metabolites and enhancing accumulation of flavonoids, phenolic acids and phenylamides. This study provides valuable insights into the complex responses and adaptive mechanisms of stylo to P deficiency.

Abstract
Background Relying solely on altruistic appeals may fail to fulfil the increasing demand for blood supplies. Current research has largely been attempted to determine and understand motives that serve as blood donation drivers. The Trans-Theoretical Model of behaviour change (TTM) can be used to conceptualise the process of intentional blood donation behaviour. Methods A cross sectional survey of Spanish adults was conducted. The final sample consisted of 504 individuals who were administered a self-report questionnaire including the measures of demographic characteristics, Stages of Change, Processes of Change, Self-efficacy and Decisional Balance. Data were analysed by frequency analysis, MANOVA/ANOVA and correlation analysis. Results Findings indicated that most of the behavioural and cognitive processes of change, self-efficacy and physical cons differentiated participants across the stages of change of blood donation. In contrast, eligibility cons and pros were less influential in stage transitions. Furthermore, significant correlations were observed between TTM constructs except for the physical cons and the processes of change. Conclusions The present study extensively supports and replicates the applicability of the TTM to blood donation behaviour change and offers important implications for the development of effective stage-matched interventions to increase blood donation.

Abstract
Objective

To investigate the relationship between serum platelet-derived growth factor (PDGF) and vulnerable plaque in patients with non-ST-elevation acute coronary syndrome (NSTE-ACS).Methods

A total of 65 patients with coronary artery disease were divided into vulnerable plaque group (n=46) and vulnerable plaque and stable plaque group (n=19) according to intravascular ultrasound (IVUS) examinations. Total cholesterol (TC), triglycerides (TG), low-density lipoprotein cholesterol (LDL-C), high-density lipoprotein cholesterol (HDL-C) and serum PDGF were measured. Plaque characteristics and components were analyzed using gray-scale and iMap-IVUS. Correlation was performed between plaque characteristics and ACS markers. Logistic regression analysis was applied to determine risk factors. Receiver operating characteristic (ROC) curve was used to evaluate the predictive value.Results

Patients in vulnerable plaque group had visible higher levels of TG, LDL-C and PDGF ( P < 0.05). There were significant differences in minimal lumen area (MLA), plaque area, plaque burden, fibrotic (FI), clipidic (LI) and necrotic core (NC) between the two groups ( P < 0.05). PDGF was weakly correlated with plaque burden (R=0.428, P < 0.05), as well as moderately correlated with NC (R=0.669, P < 0.05). Multivariate analysis showed that serum PDGF (OR 4.751, [95% CI 1.534-29.543], P =0.05) was an independent risk factor of vulnerable plaque. The area under the curve (AUC) was 0.876 (95% CI 0.804-0.948, P =0.001).Conclusion

Serum PDGF could be used as a novel biomarker for the prediction of vulnerable plaque in patients with NSTE-ACS.

Abstract
Background: Mucopolysaccharidosis type II (MPS II) or Hunter syndrome is an X-linked recessive lysosomal storage disorder resulting from deficient activity of iduronate 2-sulfatase ( IDS ) and the progressive lysosomal accumulation of sulfated glycosaminoglycans (GAGs). Methods : A diagnosis of MPS II or Hunter syndrome was performed based on the following approach after a clinical and paraclinical suspicion. Two biochemical and molecular tests were carried out separately and according to the availability of the biological material. Results : All patients in this cohort presented the most common MPS II clinical features. Electrophoresis of GAGs on a cellulose acetate plate in the presence of a high concentration of heparane sulfate showed an abnormal dermatan sulfate band in the patients compared with that in a control case. Furthermore, leukocyte IDS activity ranged from 0.00 to 0.75 nmol/h/mg of proteins in the patients. Five previously reported mutations were identified in the study patients: one splice site mutation, c.240+1G>A; two missense mutations, p.R88P and p.G94D; a large deletion of exon 1 to exon 7; and one nonsense mutation, p.Q396*. In addition, two novel alterations were identified in the MPS II patients: one frame shift mutation, p.D450Nfs*95 and one nonsense mutation, p.Q204*. Additionally, five known IDS polymorphisms were identified in the patients: IVS3-16 (c.419-16 delT), p.T214 M (c.641C>T), p.T146T (c.438 C>T), IVS5-87 (c.709-87G>A), and IVS7+38 (c.1006+38T>C). Conclusions : The high level of urine GAGs and the deficiency of iduronate 2-sulfatase activity was associated with the phenotype expression of Hunter syndrome. Molecular testing was useful for the patients’ phenotypic classification and the detection of carriers.

Abstract
Background The recurrence rate of classic surgery for anal fistula has always been one of the troublesome problems. The purpose of this study was to mainly compare the recurrence rate between classic surgery (fistulectomy or seton) and proximal anal sinus resection (PASR) in case-control study.Methods 106 patients who suffered from anal fistula were taken into classic surgery group (n=74) and PASR group (n=32), Then we analyzed the recurrence rate, wound healing time, surgical complications, and duration of the pain.Results There was a significant difference in the recurrence rate between classic surgery group and PASR group (16.2% vs 0%). The duration of pain, mean healing time and surgical complications in the two groups had no significant difference (P>0.05).Conclusion PASR had shown lower recurrence rate and did not increase the risk of complications, and could be considered as a first line of treatment for patients at risk of recurring for anal fistula.

Published: October 2019

Abstract
Background: Management of periprosthetic hip infections (PHIs) generally consists of implant removal and thorough debridement, accompanied by appropriate antibiotic therapy. Daptomycin (DAP) is a novel antibiotic, which allowed for implant retention in several patients after treating their infected joints. However, there is no consensus about implant retention or removal during treatment of PHIs. The aim of this study was to examine the effect of DAP, and to determine a surgical treatment strategy. Methods: This study retrospectively evaluated 20 patients between August 2014 and December 2018, divided into implant retention (n = 9) and implant removal groups (n = 11). Infection control and risk of recurrent infection were evaluated. Infection control was defined as not requiring implant removal after the final treatment. Results: Infection control rates in implant retention and implant removal groups were 67% and 90%, respectively. All late chronic infections resulted in failure cases within the implant retention group. In the implant retention group, mean preoperative risk scores for successful cases were significantly higher than those for failure cases (p < 0.05). Conclusions: Patients with low-risk did not require implant removal, suggesting that DAP may be a breakthrough alternative to traditional PHI management.

Abstract
Colorectal cancer (CRC) is one of the most deadly gastrointestinal malignancies. The openness of the Cancer Genome Atlas (TCGA) allows us to perform correlation analysis between large-scale transcriptome data and overall survival (OS) of multiple malignancies. Previous literature reports that the infiltration of immune cells and stromal cells in the tumor microenvironment (TME) significantly associate with the prognosis of cancers. Based on the ESTIMATE algorithm, the immune and stromal components in TME can be quantified by immune and stromal scores. To determine the effects of immune and stromal cell associated genes on CRC prognosis, we divided the CRC cases into high- and low-groups based on the immune/stromal scores and identified 999 differentially expressed genes (DEGs). Heatmaps, functional enrichment analysis and protein‐protein interaction (PPIs) networks further indicated that 999 DEGs mainly participated in stromal composition and immune response. Finally, we obtained 56 genes that were significantly associated with CRC prognosis from 999 DEGs and identified the PPIs networks. The role of 41 genes in CRC has been reported in previous literature, and the other 15 genes have never been reported. Therefore, we found 15 novel TME genes associated with CRC prognosis waiting for more researches.

Abstract
Background Some previous studies have suggested that there is an association between air pollutants and circulatory and respiratory diseases. However, the association of air pollutants and outpatient visits considering mortality, hospitalization rates, etc. has been analyzed in relatively few studies.Methods We used a generalized linear Poisson model was constructed to study the association between air pollution and outpatient visits for respiratory and circulatory diseases during 2016-2018 in coastal area of China.Results In the single pollutant model, NO 2 had a significant effect. For lag day 0 to lag day 5, the effect decreased with every 10 µg/L increase in NO 2 . O 3 and upper respiratory outpatient visits were positively associated in the cold period [lag2, ER (95%CI): 1.68% (0.44%-2.94%)], while O 3 and respiratory disease were positively associated in the warm period [lag5, ER (95%CI): 1.10% (0.11%-2.10%) and lag4, ER (95%CI): 1.02% (0.032%-2.02%)]. Similarly, PM 10 and lower respiratory diseases were positively associated in the warm period [lag0, ER (95%CI): 1.68% (0.44%-2.94%)]. When the concentration of O 3 was higher than 100 μg/L, there was a positive effect on circulatory [lag5, ER (95%CI): 2.83% (0.65%-5.06%)], respiratory [lag5, ER (95%CI): 2.47% (0.85%-4.11%)] and upper respiratory [lag5, ER (95%CI): 3.06% (1.38%-4.77%)] outpatient visits. The variation in O 3 changed slightly when we adjusted for the other air pollutants, and after adjusting for O 3 , the ERs of the other air pollutants changed slightly. After adjusting for PM 2.5 , the ER of the other air pollutants increased, and after adjusting for NO 2 , the ER of particulate matter (PM) decreased.Conclusion Exposure to ambient NO 2 , O 3 , PM 2.5 and PM 10 was associated with an increase in respiratory and circulatory system outpatient visits in coastal area of China.

Published: October 2019

Abstract
Background: The displacement of window of implantation (WOI) has been proposed as an important factor contributed to RIF. However, endometrial histological dating as the diagnostic tool of endometrial receptivity has been questioned.
Methods : This is a prospective intervention trial including 205 infertile patients from July 2017 to December 2017.Endometrial biopsies from 50 good prognosis patients were conducted on day 3(n=6), 5(n=6), 7(n=26), 9(n=6) or 11(n=6) of post-ovulation (PO+3/5/7/9/11) in the previous natural cycle before their conventional frozen-thawed embryo transfer (FET) cycle. The endometrial biopsies of 155 RIF patients were conducted on day of PO +7.
Results: The verification of Noyes criterion for endometrial dating was conducted in different time (PO +3/+5/+7/+9/+11) from 41 good prognosis patients achieving ongoing pregnancy in the first conventional FET cycle after the endometrial biopsies. The agreement between two pathologists for endometrium dating in infertile patients was determined to be good (weighted kappa = 0.672; P < 0.001). The rate of out-of-phase dating on the day of PO+7 was significantly higher in RIF patients than good prognosis patients (31.6% vs 3.8%, P=0.003).pFET was performed in 47 RIF patients diagnosed to be out of phase, and the accumulative live birth rate was 55.7%.
Conclusions: The endometrial histological dating in RIF patients in natural cycle may be a endometrial receptive biomarker for diagnosing the displacement of WOI.
Diagnosis of Rare Diseases: A scoping review of clinical decision support systems

Published: October 2019

Abstract
Background
Rare Diseases (RD), which are defined as diseases affecting not more than 5 out of 10,000 people, are often severe, chronic, degenerative and life-threating. A main problem is the delay in diagnosis of RD. Clinical Decision Support Systems (CDSS) for RD are software-systems to support physicians in the diagnosis of patients with RD. It would therefore be useful to get a comprehensive overview of which CDSS are available and can be used under what conditions. In this work we provide a review of current CDSS in RD and which functionality and data are used by the CDSS.
Methods
We searched Pubmed and Cochrane for CDSS in RD published between December 1, 2008 and December 16, 2018. Only English articles, original peer reviewed journals and conference paper describing a clinical prototype or a routine use of CDSS where included. A total of 2076 articles were found and following a screening step 16 articles (describing 13 different CDSS) were considered as relevant for the final analysis. We then described and compared the CDSS using the defined categories “functionality”, “development status”, “type of clinical data” and “system availability”.
Results
Three types of CDSS for RD were identified: “Machine Learning and Information retrieval”, “Web Search”, and “Phenotypic and genetic matching”. 8 of the 13 reviewed CDSS are publicly available and for use by physicians. The other remaining CDSS are clinical prototypes which have been applied in clinical studies but are not accessible to others. Only one clinical prototype online.
The approaches of the CDSS differ depending on what type of clinical data is used. “Machine Learning and information retrieval” can show recommendations for a diagnosis, while Web “search CDSS” will retrieve articles from literature databases (e.g. case reports), which may provide hints for a possible Diagnosis. CDSS in “Phenotypic and genetic matching” can identify similar patients based on genetic or phenotypic data.
Conclusions
Different CDSS for different purposes have been established and physicians have to decide which CDSS is more accurate for a particular patient case. It remains to be seen which of the CDSS will be used and maintained in the future.

Abstract
Background To investigate the effect of initial refractive error on the control of myopia by orthokeratology. Methods Retrospective study. Data were analyzed from 78 patients (156 eyes) who underwent orthokeratology in Beijing Children's Hospital from January 2014 to April 2018. The changes of axial length and diopter after wearing the lenses were measured. Patients were divided into six groups according to refractive error: <-1.00D, -1.00~ -2.00D, -2.00D~ -3.00D, -3.00D~ -4.00D, -4.00D~ -5.00D and -5.00~ -6.00D. A mixed-effect model was used to analyze the relevant data. At the same time, the interaction item between diopter and wearing time was analyzed, and the influence of gender was corrected. Results Patients averaged 12.9±2.161 years old. Two years after wearing orthokeratology lenses, there was a statistically significant difference with the interaction item between refractive error and wearing time in each group. The estimated values ​​were 0.0631 for the right eye and 0.053 for the left eye. Orthokeratology lenses controlled the progression of myopia well, but the reduction depended on the initial diopters. Binocular axial length examination didn’t show statistically significant difference with the interaction item. Axial length increased with time, and the magnitude of increase did not differ among groups. However, the increase in the axial length of the male more than that of the female.Conclusion Initial refractive errors have a significant impact on the control of myopia by orthokeratology. The less severe myopia patient demonstrated a more pronounced benefits after wearing orthokeratology lenses. Key words: refractive error; myopia; orthokeratology
