Abstract
Background: This study investigated the association between presenteeism and the perceived availability of social support among hospital doctors in China.Methods: A questionnaire was administered by doctors randomly selected from 13 hospital in Hangzhou China using stratified sampling. Logit model was used for data analysis.Results: The overall response rate was 88.16%. Among hospital doctors, for each unit increase of the perceived availability of social support, the prevalence of presenteeism was decreased by 8.3% (OR=0.91, P=0.000). In particular, if the doctors perceived availability of appraisal support, belonging support and tangible support as sufficient, the act of presenteeism was reduced by 20.2% (OR=0.806, P=0.000) 20.4% (OR=0.803, P=0.000) and 21.0% (OR=0.799, P=0.000) respectively with statistical differences.Conclusion: In China, appraisal support, belonging support and tangible support, compared to other social support, had a stronger negative correlation with presenteeism among hospital doctors. The benefits of social support in alleviating doctors’ presenteeism warrant further investigation.

Published: June 2020

Abstract
Background: Myopic choroidal neovascularization (CNV) is the most common sight threatening complication in high myopia. The present study evaluates the efficacy and safety of intravitreal injection of ziv-aflibercept in patients with myopic CNV. Methods: This is a prospective interventional study that was conducted on 20 eyes of 20 patients with active myopic CNV. Twelve patients were 40 years old or more. The study was performed in Ophthalmology department, Tanta University Eye Hospital ,Tanta University, Egypt. Complete ophthalmic evaluation was performed including best corrected visual acuity (BCVA), fundus examination and anterior segment examination. OCT was done for all patients at baseline and monthly after injection during the 6 months follow up period of the study. Statistical calculations were performed using the computer program SPSS (S tatistical Package for the Social Science) . Results: The younger age group received lower number of injections than the older age group, the best corrected visual acuity ( BCVA) and the central macular thickness (CMT) improved significantly in both groups with more improvement in the younger age group as regarding the BCVA. No significant correlation was found between the final BCVA and both the spherical equivalent and the central macular thickness after 6 months.No significant changes in IOP after intravitreal injection were detected in both groups .No complications were reported apart from mild sub conjunctival hemorrhage that occurred in three eyes after injection. Conclusion: Ziv-aflibercept is a highly effective and safe drug in cases of active myopic CNV that can produce similar results to other anti VEGF agents with less cost. The study was retrospectively registered with clinical trial .gov ID (NCT04290195) in 26-2-2020.

Published: June 2020

Abstract
Background: Recent increases in understanding the ecological and evolutionary roles of microbial communities has underscored the importance for their hosts’ biology. Yet, little is known about gut microbiota dynamics during early stages of ecological diversification and speciation. We sequenced the V4 region of the 16s rRNA gene to study the gut microbiota of Nicaraguan Midas cichlid fish ( Amphilophus cf. citrinellus ). Specifically, we tested the hypothesis that parallel divergence in trophic ecology in extremely young adaptive radiations from two crater lakes is associated with parallel changes of their gut microbiota. Results: Bacterial communities of fish guts and lake water were highly distinct, indicating that the gut microbiota is shaped by host-specific factors. Among individuals of the same crater lake, differentiation in trophic ecology was weakly associated with gut microbiota differentiation, suggesting that diet, to some extent, affects the gut microbiota. However, differences in trophic ecology were much more pronounced across than within species whereas similar patterns were not observed for taxonomic and functional differences of the gut microbiota. Across the two crater lakes, we could not detect conclusive evidence for parallel changes of the gut microbiota associated with trophic ecology. Conclusions: A lack of clearly differentiated niches during early stages of ecological diversification might result in non-parallel changes of gut microbial communities, as observed in our study system as well as in other recently diverged fish species.

Abstract
Background: Genetic factors such as single nucleotide polymorphisms (SNPs) play a key role in the development of postoperative nausea and vomiting (PONV). However, previous findings are not widely applicable to different populations because of population-specific genetic variation. We developed a Japanese-specific DNA microarray for high-throughput genotyping. The aim of the current study is to identify causal SNPs associated with PONV on a genome-wide scale using this microarray in a sample of Japanese surgical patients. associations between 659,636 SNPs and the incidence of PONV 24 h after surgery in a limited sample of 24 female patients using the microarray. After imputation of genotypes at 24,330,529 SNPs, 78 SNPs were found to be associated with the incidence of PONV. We chose 4 of the 78 SNPs to focus on by in silico functional annotation. Finally, we genotyped these 4 candidate SNPs in 255 patients using real-time PCR to verify association with the incidence of PONV. Results: The T > C variant of rs11232965 in the long non-coding RNA MIR4300HG was significantly associated with reduced incidence of PONV among genotypes and between alleles (p = 0.01 and 0.007). Conclusions: We identified a novel causal SNP (rs11232965) in the long non-coding RNA MIR4300HG that is associated with PONV. The rs11232965-SNP variant (T > C) is protective against the incidence of PONV. Trial registration: This study was registered at the UMIN Clinical Trials Registry (Identifier: UMIN000022903, date of registration: June 27th, 2016, retrospectively registered, https://upload.umin.ac.jp/cgi-open-bin/ctr_e/ctr_view.cgi?recptno=R000026392).

Authors: Yang Qing , Yu Xuexin , Zhang Wei 
Published: June 2020

Abstract
Background: The aim of this study was to obtain health utility data for Chinese breast cancer patients in different disease states to obtain important parameters for health economics modelling and to explore the feasibility of establishing a breast cancer health utility mapping model in China.Methods: Multiple patient-reported health attributes were assessed, including quality of life, which was measured by the Functional Assessment of Cancer Therapy-Breast (FACT-B) instrument; health utility and self-rated health, which were measured by the EuroQol-5 Dimension-5 Level (EQ-5D-5L) questionnaire. Multivariate regression models, including a linear regression model, an ordinal logistic regression model and a Tobit model, were employed to analyse health differences among 446 breast cancer patients. Subgroup analyses were performed to analyse differences in the dimensions of health derived from the FACT-B and EQ-5D-5L instruments. A mapping function was used to estimate health utility from quality of life. Rank correlation analyses were employed to examine the correlation between estimated and observed health utility values.Results: A total of 446 breast cancer patients with different disease states were analysed. The health utility values of breast cancer patients in the P state (without cancer recurrence and metastasis), R state (with cancer recurrence within a year), S state (with primary and recurrent breast cancer for the second year and above), and M state (metastatic cancer) were 0.81 (SD±0.23), 0.90 (SD±0.12), 0.78 (SD±0.31), and 0.74 (SD±0.27), respectively. There were positive correlations between all scores, including each domain of the FACT-B instrument (p<0.001). Multivariate analysis suggested that patients in the R and M states had lower scores for overall quality of life (R, β = -9.45, p< 0.01; M, β = -6.72, p<0.05). Patients in the M state had lower health utility values than patients in the P state (β = -0.11, p< 0.05). Estimated health utility values, which were derived from quality of life using a mapping function, were significantly correlated with directly measured health utility values (p<0.001).Conclusions: We obtained the health utility and health-related quality of life (HRQoL) scores of Chinese breast cancer patients with different disease states. Mapping health utility values from quality of life using four disease states could be feasible in health economic modelling, but the mapping function may need further revision.

Abstract
Background: Glioblastoma multiforme (GBM) is the most common and lethal type of primary brain tumor. More than half of GBMs contain mutation(s) of PTEN/PI3K/AKT, making inhibitors targeting the PI3K pathway very attractive for clinical investigation. However, so far, PI3K/AKT/mTOR inhibitors have not achieved satisfactory therapeutic effects in clinical trials of GBM. In this study, we aimed to develop a high-throughput screening method for high-throughput identification of potential targeted agents that synergize with PI3K inhibitors in GBM.Methods: A Sensitivity Index (SI)-based drug combination screening method was established to evaluate the interactions between BKM120, a pan-PI3K inhibitor, and compounds from a library of 606 target-selective inhibitors. Proliferation, colony and 3D spheroid formation assays, western blotting, comet assay, γ-H2AX staining were used to evaluate the anti-glioma effects of the top-ranked candidates. The drug combination effects were analyzed by the Chou-Talalay method. Results: Six compounds were successfully identified from the drug screen, including three previously reported compounds that cause synergistic antitumor effects with PI3K/mTOR inhibitors. TH588, an MTH1 inhibitor exhibited significant synergy with BKM120 in suppressing the proliferation, colony formation and 3D spheroid formation of GBM cells. Further investigation revealed that both DNA damage and apoptosis were markedly enhanced upon combination treatment with TH588 and BKM120. Finally, activation of PI3K or overexpression of AKT compromised the anti-glioma efficacy of TH588.Conclusions: The screening method developed in this study demonstrated its usefulness in the rapid identification of synergistic drug combinations of PI3K inhibitors and targeted agents.

Published: June 2020

Abstract
BACKGROUND
Dry eye syndrome in which tear fluid quality or abnormality or kinetic abnormality is caused by many causes, resulting in decreased tear film stability. In recent years, more and more results from the studies indicate that miRNA alterations are involved in dry eye syndrome. And miRNA-146a-5p is a key regulator to regulate the inflammatory response. In this paper, we demonstrated whether miRNA-146a-5p could cure dry eye syndrome by regulating target genes based on network analysis.
METHODS
In this paper, we collected the blood of patients with dry eye disease served as model group, the blood of healthy people was served as control group. The expression of miRNA-146a-5p in the patients were detected by RT-PCR, the genes controled by miRNA-146a-5p were predicted by Targetscan, miRDB, miRWalk and PicTar databases, the genes regulated by miRNA-146a-5p which relative with dry eye disease were selected by draw venn diagram;
RESULTS
The comparison of the general information between patients and healthy people were no significant difference, and it indicated that the two groups were comparable. The results of databases showed that IRAK1 was one of the target genes regulated by miRNA-146a-5p and it is related to dry eye disease. The expression of miRNA-146a-5p was negatively related to IRAK1 mRNA and protein. While IRAK1 had positive correlation with IL-6, TNF-α and CBP proteins.
CONCLUSIONS
These results emphasized that miRNA-146a-5p could inhibit the expression of IRAK1, IL-6, TNF-α and CBP so as to help reduce the inflammatory response in dry eye syndrome.

Abstract
Background: The neuroprotective role of interleukin (IL)-33 is supported by numerous pre-clinical studies, but it remains uninvestigated in clinical studies of Alzheimer’s disease (AD). We aimed to examine the association between human blood levels of IL-33 and cognitive preservation in amnestic mild cognitive impairment (aMCI) and AD.Methods: A total of 100 participants (26 controls, 35 aMCI patients, and 39 AD patients) completed two Mini Mental State Examination (MMSE) over a 1-year interval. In all 100 participants at the second MMSE, we examined the plasma levels of IL-33, IL-β, IL-1 receptor agonist (IL-1RA), beta amyloid (Aβ), and tau and apolipoprotein E (ApoE) genotyping; we also performed Hopkins Verbal Learning Test, Trail Making Test, forward and backward digit span, and Clinical Dementia Rating. Results: IL-33 expression showed a positive trend among controls (1/26 = 3.8%), aMCI (9/35 = 25.7%), and AD (17/39 = 43.6%) (trend analysis: P < 0.001). Patients expressing IL-33 preserved their cognitive function compared with IL-33 non-expressing patients (1-year ΔMMSE: 0.16 ± 1.6 vs -1.5 ± 2.6; P = 0.006). The cognitive preservation was not associated with the lower levels of Aβ, tau, and ApoE ε4, while higher levels of ApoE ε4 and phosphorylated tau were indeed associated with cognitive decline. The aMCI patients with AD conversion during study period had higher proportion of IL-33(-) than non-AD converters (90.9% vs 53.3%, P = 0.04).Conclusions: IL-33 or its associated signaling pathways may represent a new treatment paradigm for aMCI and AD.

Published: June 2020

Abstract
Background: There is an increased interest in quantifying and characterizing epicardial fat which has been linked to various cardiovascular diseases such as coronary artery disease and atrial fibrillation. Recently, three-dimensional single-phase Dixon techniques have been used to depict the heart and to quantify the surrounding fat. The purpose of this study was to investigate the merits of a new high-resolution cine 3D Dixon technique for quantification of epicardial adipose tissue and compare it to single-phase 3D Dixon in patients with cardiovascular disease. Methods: Fifteen patients referred for clinical CMR examination of known or suspected heart disease were scanned on a 1.5T scanner using single-phase Dixon and cine Dixon. Epicardial fat was segmented by three readers and intra- and inter-observer variability was calculated per slice. Cine Dixon segmentation was performed in the same cardiac phase as single-phase Dixon. Subjective image quality assessment of water and fat images were performed by three readers using a 4-point Likert scale (1=severe; 2=significant; 3=mild; 4=no blurring of cardiac structures).Results: Intra-observer variability was excellent for cine Dixon images (ICC=0.96), and higher than single-phase Dixon (ICC=0.92). Inter-observer variability was good for cine Dixon (ICC=0.76) and moderate for single-phase Dixon (ICC=0.63). The intra-observer measurement error (mean ± standard deviation) per slice for cine was -0.02±0.51 ml (-0.08±0.4%), and for single-phase 0.39±0.72 ml (0.18±0.41%). Inter-observer measurement error for cine was 0.46±0.98 ml (0.11±0.46%) and for single-phase 0.42±1.53 ml (0.17±0.47%). Visual scoring of the water image yielded median of 2 (interquartile range = [Q3-Q1] 2-2) for cine and median of 3 (interquartile range = 3-2) for single-phase (P < 0.05) while no significant difference was found for the fat images, both techniques yielding a median of 3 and interquartile range of 3-2. Conclusion: Cine Dixon can be used to quantify epicardial fat with lower intra- and inter-observer variability compared to standard single-phase Dixon. The time-resolved information provided by the cine acquisition appears to support the delineation of the epicardial adipose tissue depot.

Authors: lin jian 
Published: June 2020

Abstract
Significance: It is generally believed that cycloplegia optometry had no effect on astigmatism. The comparison was all made on the spectacle plane. There is a dearth of studies on the influence from corneal plane. Purpose: Study on the difference between cycloplegic and noncycloplegic measurements of astigmatism on corneal plane. Methods: This is a retrospective study. Vertexing the total ocular astigmatism to the corneal plane. To transpose astigmatism into J0 and J45 components by Fourier transformation. The changes of astigmatism measured with and without cycloplegic were compared from corneal plane. Data were compared by paired t test. Results: The changes of the total ocular astigmatism were significantly different on corneal plane (total ocular astigmatism: t = -2.31, P < .05; J0 components: t = -2.71, P < .01; J45 components: t = -1.09, P༞.05). The magnitude of total ocular astigmatism generally increased after cycloplegia (2.12 ± .87 D vs 2.07 ± .89 D). 37 eyes (32.17%) had a change value greater than 0.25 D. The proportion of with-the-rule total ocular astigmatism increased (from 90.43–92.17%) and that of oblique total ocular astigmatism decreased (from 9.57–7.83%). While the changes of anterior corneal astigmatism were no significantly different . Conclusion: There were underestimation of total ocular astigmatism without cycloplegic refraction in preschool children. The proportion of with-the-rule astigmatism increases after cycloplegia.
Advancing integrated care evaluation in shifting contexts: Blending implementation research with case study design in Project SUSTAIN.

Published: June 2020

Abstract
Background
Despite many studies evaluating the effectiveness of integrated care, evidence remains inconsistent. There is increasing commentary pointing out the mismatch between the ability to capture the somewhat ‘illusive’ impact of integrated care initiatives and programmes, and the most appropriate way to do this. Focusing on methodology, this paper describes and critically reviews the experiences of SUSTAIN, a Horizon 2020 funded project (2015–2019) with the purpose of advancing knowledge and understanding of cross-European integrated care evaluation. SUSTAIN sought to improve integrated care initiatives for older people in seven countries, and to maximise the potential for knowledge transfer and application across Europe. The methods approach drew from implementation research, employing the participative Evidence Integration Triangle (EIT) and incorporating a mixed method, multiple embedded case study design. A core set of qualitative and quantitative indicators, alongside context and process data, were created and tested within four key project domains (person-centredness, prevention-orientation, safety and efficiency). The paper critically discusses the overall approach, highlighting the value of the EIT and case study design, and signalling the challenges of data collection with frail older people and stakeholder involvement at the sites, as well as difficulties developing the core set of indicators.
Conclusions
Lessons learned and recommendations for advancing integrated care evaluation are put forward that focus on the status of integrated care as a complex intervention and a process. The use of implementation research methods and case study design are recommended, alongside suggested ways of improving methods of data collection with frail populations and cost analysis.
A case-control study on psychotropic substance use and risk of Axis I psychiatric disorders in HIV-infected gay or bisexual men in Hong Kong
Authors: Lee Chi Kei Krystal , Chung Kar Kin Albert 
Published: June 2020

Abstract
Background: Psychotropic substance use is common in HIV-infected gay or bisexual men (GBM). This study examined the association between Axis I psychiatric disorders and active psychotropic substance use, and identified factors affecting the prevalence of psychiatric disorders in HIV-infected GBM.Methods: This is a cross-sectional case-control study taken place in an HIV clinic and community organisations serving people living with HIV or GBM in Hong Kong. Participants were 62 HIV-infected self-identified GBM who reported psychotropic substance use in the past 1 year (cases), and 55 HIV-infected self-identified GBM without psychotropic substance use in the past 1 year and had negative toxicology tests at recruitment (controls).The Chinese-bilingual Structured Clinical Interview for DSM-IV (Axis I, Patient version) was followed to establish the psychiatric diagnoses. Socio-demographic data, level of social support, HIV-related data, and pattern of psychotropic substance use were collected. Results: Cases had lower level of social support (p=0.02), more depressive disorders (AOR 3.4, 95% CI 1.3-8.7, p=0.01) and psychotic disorders (AOR 7.2, 95% CI 1.2-41, p=0.03) but not anxiety disorders. Significant difference in the prevalence of psychiatric disorders was only evident for disorders with onset after HIV diagnosis. Methamphetamine dependence (AOR 6.63, 95% CI 1.53-228.72, p<0.01), weekly methamphetamine use for 2 years or more (AOR 18.6, 95% CI 1.26-274.69, p=0.03), using methamphetamine beyond chemsex (AOR 4.76, 95% CI 1.17-19.41, p=0.03) were significant predictors for psychiatric disorders in the cases in separate logistic regression models. Duration of HIV diagnosis was a significant independent predictor in all three models. Conclusions: Active psychotropic substance use in HIV-infected gay or bisexual men was associated with a 3-fold increase in Axis I psychiatric disorders. This increase in psychiatric disorders was predicted by the severity, duration and context of methamphetamine use and the duration of HIV diagnosis.
