Abstract
Background: As the large number of Community Health Service (CHS) centers in China face the majority of non-valvular atrial fibrillation (NVAF) patients, primary care physicians (PCPs) play the primary role in the prevention of embolization. Therefore，an awareness of anticoagulant management in NVAF patients must be brought into focus among PCPs in China. This study will investigate PCPs’ Knowledge, Attitude and Practice toward anticoagulant therapy in patients with NVAF and help PCPs increase their awareness of oral anticoagulant (OAC) therapy for NVAF to prevent embolization. Method: This was a cross-sectional observational study of 462 PCPs in CHS centers across Shanghai. We used a self-administered questionnaire to collect data from September to December 2017. A stratified random cluster sampling was adopted in the 90 CHS centers with the family medicine residency program. Result: Among 462 participants, 69.3% (320/462) of females got a medical bachelor’s degree and over 50% participants had more than 10 years of work experience. According to similar study, each section for knowledge, attitude, and practice were categorized as poor (≤39.0%), fair (40.0%–69.0%), and good (≥70.0%) [18] . The level of knowledge of OAC therapy in patients with NVAF among PCPs was insufficient in over half (75.8%) of participants. The majority (89.8%) of PCPs had a positive attitude and 68.0% had modest performance in the anticoagulant management of patients with NVAF. Conclusion: The knowledge and behaviors of PCPs were insufficient in OAC therapy to prevent embolization in patients with NVAF. The study also revealed there is good potential for PCPs’ educational interventions to positively impact on the care of patients with NVAF.

Abstract
Background: Several frameworks have been developed to identify essential determinants for healthcare improvement. These frameworks aim to be comprehensive, leading to the creation of long lists of determinants that are not prioritised based on being experienced as most important. Furthermore, most existing frameworks do not describe the methods or actions used to identify and address the determinants, limiting their practical value. The aim of this study is to describe the development of a tool with prioritised facilitators and barriers supplemented with methods to identify and address each determinant. The tool can be used by those performing quality improvement initiatives in healthcare practice. Methods: A mixed-methods study design was used to develop the tool. First, an online survey was used to ask healthcare professionals about the determinants they experienced as most facilitating and most hindering during the performance of their quality improvement initiative . A priority score was calculated for every named determinant, and those with a priority score ≥ 20 were incorporated into the tool. Semi-structured interviews with implementation experts were performed to gain insight on how to analyse and address the determinants in our tool Results: The 25 healthcare professionals in this study experienced 64 facilitators and 66 barriers when performing their improvement initiatives. Of these, 12 facilitators and nine barriers were incorporated into the tool. Sufficient support from management of the department was identified as the most important facilitator, while having limited time to perform the initiative was considered the most important barrier. The interviews with 16 experts in implementation science led to various inputs for identifying and addressing each determinant. Important themes included maintaining adequate communication with stakeholders, keeping the initiative at a manageable size, learning by doing and being able to influence determinants. Conclusions: This paper describes the development of a tool with prioritized determinants for performing quality improvement initiatives with suggestions for analysing and addressing these determinants. The tool is developed for those engaged in quality improvement initiatives in practice, so in this ways it helps to bridging the research to practice gap of determinants frameworks. More research is needed to validate and develop the tool further.

Abstract
Background: A bacterial biosensor refers to genetically engineered bacteria that produce an assessable signal in the presence of a physical or chemical agent in the environment.Methods: We have designed and evaluated a bacterial biosensor expressing a luciferase-reporter gene controlled by pbr and cadA promoters in Cupriavidus metallidurans (previously termed Ralstonia metallidurans ) containing the CH34 and pI258 plasmids of Staphylococcus aureus , respectively, and that can be used for the detection of heavy metals. In the present study, we have produced and evaluated biosensor plasmids designated pGL3-luc/pbr -biosensor and pGL3-luc/cad -biosensor, that were based on the expression of luc+ under the control of the cad promoter and the cadC gene of S. aureus plasmid pI258 and pbr promoter and pbrR gene from plasmid pMOL30 of Cupriavidus metallidurans.Results: We found that the pGL3-luc/pbr -biosensor may be used to measure lead concentrations between 1-100 μM in the presence of other metals, including: zinc, cadmium, tin and nickel. The latter metals did not result in any significant signal gene expression of the reporter. The pGL3-luc/cad -biosensor could detect lead concentrations between 10 nM to 10 μM.Conclusions: This biosensor was found to be a specific for measuring lead ions in both environmental and biological samples.

Published: August 2020

Abstract
Background

A questionnaire assessing awareness of positive and negative age-related changes (AARC gains and losses) was developed in the US and Germany. We validated the short form of the measure (AARC-10 SF) and the cognitive functioning subscale from the 50-item version of the AARC (AARC-50) questionnaire in the UK population aged 50 and over.

Methods

Data from 14,797 participants in the PROTECT cohort were used to explore and confirm the psychometric properties of the AARC measures including: validity of the factor structure; reliability; measurement invariance across males and females and across individuals with and without a university degree; and convergent validity with measures of self-perception of aging and mental, physical, and cognitive health. We also explored the relationship between demographic variables and AARC.

Results

We confirmed the two-factor structure (gains and losses) of the AARC-10 SF and the AARC-50 cognitive functioning subscale. Both scales showed good reliability and convergent validity. The meaning of AARC gains and losses was the same across males and females and across individuals with and without a university degree. Items composing AARC scales had the same meaning across individuals with and without a university degree. Items composing the AARC-50 cognitive functioning subscale had the same meaning across males and females. Two items in the AARC-10 SF had different meaning across males and females. Demographic variables significantly predicted AARC gains and losses.

Conclusions

The AARC-10 SF and AARC-50 cognitive functioning subscale can help to identify UK individuals who perceive age-related changes in their mental, physical, and cognitive health.

Published: August 2020

Abstract
Aims: To ascertain the number of paediatric deaths (0-14 years) with an underlying rare disease (RD) in the Irish Republic between the years 2006-2016, and to analyse bed usage by a paediatric cohort of RD inpatients prior to in-hospital death.Background: Rare diseases are often chronically debilitating and sometimes life-threatening diseases, affecting fewer than 5 per 10,000 people in the EU. Although individually rare, collectively RDs are common, with a prevalence of 3.5-5.9% of the population. Under-representation of RDs in hospital healthcare coding systems leads to a paucity of RD epidemiological data required for healthcare planning. Studies have cited variable incidence rates for RD, however the burden of RDs to healthcare services still remains unclear. This study represents a thorough effort to identify the percentage of child mortality and paediatric bed usage attributable to rare diseases in Ireland addressing a major gap in the RD field.Methods: Retrospective analysis of paediatric death registration details for the Irish Republic in the 11-year period 2006-2016 from the National Paediatric Mortality Register. Data was subcategorised as Neonatal (0-28 days), Post Neonatal (29 days < 1 year) and older (1-14 years). Bed usage data (ICD-10 code, narrative and usage) of paediatric inpatients who died during hospitalisation from January 2015 to December 2016 was extracted from the National Quality Assurance Intelligence System of in-patient data. Orphacodes were assigned to RD cases from narrative records of both datasets.Results: There were 4044 deaths registered from 2006-2016, aged <15yrs, of these 2368 (58.6%) had an underlying RD. Stratifying by age group; 55.6% (1140/2050) of neonatal deaths had an RD, 57.8% (450/778) post-neonatal, and 64% (778/1216) of children >1yr. Mortality coding using ICD-10 codes identified 42% of RD cases with the remainder identified using death certificate narrative records. RD patients occupied 87% of bed days used by children <15 years who died during hospitalisation from January 2015 to December 2016.Conclusion: Additional routine RD coding is necessary to identify RDs within Irish healthcare systems to enable better healthcare planning. RD patients are overrepresented in paediatric mortality statistics and inpatient length of stay during hospital admission prior to death.

Published: August 2020

Abstract
Background: Peromyscus are the most common mammalian species in North America and are widely used in both laboratory and field studies. The deer mouse, P. maniculatus and the old-field mouse, P. polionotus, are closely related and can generate viable and fertile hybrid offspring. The ability to generate hybrid offspring, coupled with developing genomic resources, enables researchers to conduct linkage analysis studies to identify genomic loci associated with specific traits. Results: We used available genomic data to identify DNA polymorphisms between P. maniculatus and P. polionotus and used the polymorphic data to identify the range of genetic complexity that underlies physiological and behavioral differences between the species, including cholesterol metabolism and genes associated with autism. In addition, we used the polymorphic data to conduct a candidate gene linkage analysis for the Dominant spot trait and determined that Dominant spot is linked to a region of chromosome 20 that contains a strong candidate gene, Sox10. During the linkage analysis, we found that the spot size varied quantitively in affected Peromyscus based on genetic background. Conclusions: The expanding genomic resources for Peromyscus facilitate their use in linkage analysis studies, enabling the identification of loci associated with specific traits. More specifically, we have linked a coat color spotting phenotype, Dominant spot, with Sox10, a member the neural crest gene regulatory network, and that there are likely two genetic modifiers that interact with Dominant spot. These results establish Peromyscus as a model system for identifying new alleles of the neural crest gene regulatory network.

Abstract
Background: At present, etanercept represents the most commonly prescribed biologic agent for juvenile idiopathic arthritis (JIA) treatment. Children and adolescents with JIA are often treated with etanercept over long periods, sometimes even into adulthood. The objectives of this analysis were to determine the long-term safety of etanercept compared to a biologic-naïve cohort, and to assess the long-term treatment response upon continuous etanercept exposure using data from the German biologics registry (BiKeR).

Methods: JIA patients newly exposed to etanercept were documented in the BiKeR registry from January 2001 till March 2019, and baseline characteristics, effectiveness, as well as safety parameters were analysed. Response to treatment was assessed according to 10-joint Juvenile Arthritis Disease Activity Score (JADAS10), JADAS-defined minimal disease activity and remission, JIA-American College of Rheumatology (ACR) improvement criteria, as well as ACR-inactive disease definition. Safety assessments were based on adverse events (AE) reports.

Results: 2725 new etanercept users with a diagnosis of JIA were registered. Of these, etanercept was received as a first-line biologic by 95.8% and as monotherapy without concomitant methotrexate by 31.5%. After nine years on continuous treatment, 68.1% of patients presented minimal disease activity, 43.1% JADAS-defined remission on drug and 36.6% ACR-inactive disease. JIA-ACR30/50/70/90 response rates were still 82/79/71/54% after 9 years of treatment. Overall, 2053 AEs (34.3/100PY), including 226 serious AEs (SAE, 3.8/100PY), were observed upon etanercept, compared to 1345 AEs [35.6/100PY; p=0.3] and 52 SAEs (1.4/100PY; p=0.0001) in the biologic-naïve cohort. Respective exposure-adjusted rates for etanercept and biologic-naïve patients were 0.9/100PY and 0.2/100PY (p=0.0001) for serious infections, 0.4/100PY and 0.1/100PY (p=0.01) for zoster reactivation, 0.3/100PY and 0.03/100PY (p=0.015) for inflammatory bowel disease, 1.9/100PY and 1.4/100PY (p=0.09) for uveitis. Three and two malignancies were documented in the etanercept and biologic-naïve groups, as well as three and one deaths, respectively.

Conclusions: No new safety signal was observed, especially no increased risk for malignancies or autoimmune disorders other than inflammatory bowel disease. However, SAEs and serious infections, though infrequent, were more often reported on etanercept than in biologic-naïve patients. In addition, etanercept demonstrated a long-term maintenance of clinical benefits up to nine years of continuous treatment.

An intimate view into the silica deposition vesicles of diatoms
Authors: Heintze Christoph , Formanek Petr , Pohl Darius , Hauptstein Jannes , Rellinghaus Bernd , Kröger Nils 
Published: August 2020

Abstract
Diatoms are single-celled microalgae that produce silica-based cell walls with intricate nano- and micropatterns. Biogenesis of diatom biosilica is a bottom-up process that occurs in large intracellular compartments termed silica deposition vesicles (SDVs). Investigating the mechanism of silica morphogenesis has so far been severely limited by the lack of methods for imaging the entire volume of an SDV with high spatial resolution during all stages of development. Here we have developed a method that allows for rapid identification and electron microscopy imaging of many different, full sized SDVs that are in the process of producing biosilica valves. This enabled visualizing the development of characteristic morphological biosilica features with unprecedented spatio-temporal resolution. During early to mid-term development, valve SDVs contained ~20 nm sized particles that were primarily associated with the radially expanding rib-like biosilica structures. The results from electron dispersive X-ray analysis suggests that the immature biosilica patterns are silica-organic composites. This supports the hypothesis that silica morphogenesis is dependent on organic biomolecules inside the SDV lumen.

Published: August 2020

Abstract
Background: Periodontal health is of great concern for periodontists and orthodontists in the inter-disciplinary management of patients with bimaxillary protrusion. The aim of present study is to investigate changes in the alveolar bone in the maxillary incisor region and to explore its relationship with displacement of root apex as well as changes in the inclination of maxillary incisors during incisor retraction.Methods: Samples in this retrospective study consisted of 38 patients with bimaxillary protrusion. Cone-beam computed tomography (CBCT) images was taken before(T0) and after (T1) treatment. Alveolar bone thickness (ABT), height (ABH) and area (ABA) were utilized to evaluate changes in the alveolar bone, while incisor inclination and apex displacement were used to assess changes in the position of maxillary central and lateral incisors. Correlations between alveolar bone remodeling and apex displacement as well as changes in the inclination were investigated.Results: The labial ABT of central and lateral incisors at the mid-root third was increased. In contrast, the palatal ABT at crestal, mid-root and apical third level were consistently decreased. ABH was not altered on the labial side, while significantly decreased on the palatal side. ABA was not significantly increased on the labial side, but significantly decreased on the palatal side, leading to a significantly reduced total ABA. Orthodontic treatment significantly reduced inclination of upper incisors. Changes in the amount (T1-T0) of ABA was remarkably correlated with apex displacement and changes of inclination (T1-T0); in addition, using the multivariate linear regression analysis, changes of ABA on the palatal side (T1-T0) can be described by following equation: Changes of palatal ABA (T1-T0) = -3.258- 0.139× changes of inclination (T1-T0) + 2.533×apex displacement (T1-T0).Conclusions: Retraction of incisors in bimaxillary protrusion patients may compromise periodontal bone support on the palatal side. An equation that incorporated the displacement of root apex and change in the incisor inclination may enable periodontist-orthodontist interdisciplinary coordination in assessing treatment risks and developing an individualized treatment plan for adult patients with bimaxillary protrusion. Moreover, the equation in predicating area of alveolar bone may reduce the risks of placing the teeth out of the bone boundary during 3D digital setups.
