Abstract
Background: Large-scale, centralized data repositories are playing a critical and unprecedented role in fostering innovative health research, leading to new opportunities as well as dilemmas for the medical sciences. Uncovering the reasons as to why citizens do or do not contribute to such repositories, for example, to population-based biobanks, is therefore crucial. We investigated and compared the views of existing participants and non-participants on contributing to large-scale, centralized health research data repositories with those of ex-participants regarding the decision to end their participation. This comparison could yield new insights into motives of participation and non-participation, in particular the behavioural change of withdrawal. Methods: We conducted 36 in-depth interviews with ex-participants, participants, and non-participants of a three-generation, population-based biobank in the Netherlands. The interviews focused on the respondents’ decision-making processes relating to their participation in a large-scale, centralized repository for health research data. Results: The decision of participants and non-participants to contribute to the biobank was motivated by a desire to help others. Whereas participants perceived only benefits relating to their participation and were unconcerned about potential risks, non­-participants and ex-participants raised concerns about the threat of large-scale, centralized public data repositories and public institutes, such as social exclusion or commercialization. Our analysis of ex-participants’ perceptions suggests that intrapersonal characteristics, such as levels of trust in society and public goods, participation conceived as a social norm, and basic societal values account for differences between participants and non-participants.Conclusions: Our findings indicate the fluidity of motives centring on helping others in decisions to participate in large-scale, centralized health research data repositories. Efforts to improve participation should focus on enhancing the trustworthiness of such data repositories and developing layered strategies for communication with participants and with the public. Accordingly, personalized approaches for recruiting participants and transmitting information along with appropriate regulatory frameworks are required, which have important implications for current data management and informed consent procedures.

Abstract
Background: Research shows that physicians often report job burnout and have a high level of presenteeism, but few studies concerns the relationship between job burnout and presenteeism. The purpose of this study was to explore the relationship between physicians’ presenteeism and three dimensions of job burnout in China, and to identify aspects that are can help alleviate associated with presenteeism. Methods: A cross-sectional survey involving physicians in second-and third-class medical institutions was conducted in the interior of China. Using one item measure about presenteeism a single presenteeism questionnaire and a 15-item Chinese version of the BMI-GS questionnaire, this study investigated prevalence of physicians' presenteeism behavior and job burnout in three dimensions, and determined the relationship between presenteeism and job burnout by logistical model. Results: Relationships between presenteeism and three dimensions of job burnout were explored, and the influence of demography and work factors were evaluated. The survey was completed by 1376/1547 hospital doctors, with a response rate of 88.9%. 30.7%(n=422) of the subjects reported having presenteeism behavior. Using MBI-GS, 86.8%(n=1195) of physicians had scores of moderate job burnout were moderately burnout and 6.0%(n=82) were severely job burnout. Logistic regression analysis showed that physicians with moderate, severe emotional exhaustion and severe cynicism were more likely to engage in associate with presenteeism (all p < 0.05). In addition, two other work-related factors, including the physician's department and position, were also more likely to influence relate with their presenteeism (all p < 0.05). Conclusions: At present, there is quite presenteeism among physicians in the second-and third-class medical institutions in China, which is significantly related to emotional exhaustion and cynicism. Considering the modifiable job-related factors, health care institutions must take appropriate measures to relieve physicians' job burnout, help them adjust their self-awareness properly, and ensure occupational mental health to alleviate the prevalence of presenteeism.

Published: May 2020

Abstract
Background Specific clinical risk factors may contribute to worsening or improving neurological functions in an acute ischemic stroke (AIS) patient pre-treated with a cholesterol reducer with a subsequent recombinant tissue plasminogen activator (rtPA) treatment. We investigated clinical risk factors associated with good or poor presenting neurological symptoms in ischemic stroke patients with prior cholesterol reducer use, specifically a statin and rtPA therapy. Methods We retrospectively analyzed baseline clinical and demographic data of 630 patients with AIS taking cholesterol reducers prior to rtPA treatment from January 2010 to June 2016 in a regional stroke center. Progressing (NIHSS ≤ 7) or worsening (NIHSS > 7) scores for neurologic improvement determined measures for treatment outcome. Multivariate logistic regression models identified demographic and clinical factors associated with worsening or progressing neurologic functions. Results Adjusted multivariate analysis showed that in an ischemic stroke population with a combined rtPA and cholesterol reducer medication history, increasing age (OR = 1.032, 95% CI, 1.015-1.048, P < 0.001) and atrial fibrillation (OR = 1.859, 95% CI, 1.098-3.149, P = 0.021) demonstrated a likely association with worsening neurologic functions, while direct admission (OR = 0.411, 95% CI, 0.246-0.686, P = 0.001) and being Caucasian (OR = 0.496, 95% CI, 0.297-0.827, P = 0.007) showed an association with improving or progressing neurologic functions. Conclusion A prior cholesterol reducer, namely a statin, plus rtPA combination may be associated with worsening neurological function for elderly AIS patients with atrial fibrillation, while Caucasians directly admitted to a neurology unit are more likely to show an association with progress or improvements in neurologic functions.

Published: May 2020

Abstract
Background: Medicine is a field that is simultaneously factual and ambiguous. While studies have examined medical trainees’ tolerance of ambiguity (TOA), the extent to which TOA is affected by clinical experiences and its association with perfectionism is unknown. Methods: This was a multiple sampling, single cohort study of students in their first year of clinical clerkship which is comprised of 6 core rotations. Consenting students completed an online anonymous survey assessing their tolerance of ambiguity (TOA) and perfectionism in their first (pre) and last (post) 12 weeks of their clinical clerkship year. Tolerance of Ambiguity in Medical Students and Doctors (TAMSAD) and The Big Three perfectionism scale-short form (BTPS-SF) were used to assess TOA and perfectionism respectively. Pre-Post mean comparisons of TOA and perfectionism were assessed via t-tests. Results: From a total possible sample of 174 clinical clerkship students, 51 students responded to pre-survey, 62 responded to post-survey. Clerkship was associated with a significant decrease in TOA (p=0.00) with mean pre-TOA scores of 59.57 and post TOA of 43.8. Perfectionism scores were not significantly different over time (p>0.05). There was a moderate inverse correlation between TOA and perfectionism before clerkship (r=0.32) that increased slightly after clerkship (r=0.39). Those preferring primary care specialties had significantly lower rigid and total perfectionism scores in pre-clerkship than those choosing other specialties, but this difference was not found post-clerkship. Conclusion: We hypothesize that the decrease in TOA seen in this study may reflect an underlying anxiety cycle related to frequent rotation changes. Implications of the role of perfectionism and primary care is discussed. Overall these results require further investigation to better characterize the role of clinical exposure on TOA.

Published: May 2020

Abstract
Background Wolbachia are the most widely spread endosymbiotic bacteria, present in a wide variety of insects and two families of nematodes, but as of now, relatively little genomic data has been available. The Wolbachia symbiont can be parasitic, as described for many arthropod systems, an obligate mutualist, as in filarial nematodes or a combination of both in some organisms. They are currently classified into 16 monophyletic lineage groups ("supergroups"). Although the nature of these symbioses remains largely unknown, expanded Wolbachia genomic data will contribute to understanding their diverse symbiotic mechanisms and evolution. Results This report focuses on Wolbachia infections in three pseudoscorpion species infected by two distinct groups of Wolbachia strains , based upon multi-locus phylogenies. Geogarypus minor harbours w Gmin and Chthonius ischnocheles harbours w Cisc, both closely related to supergroup H, while Atemnus politus harbours w Apol, a member of a novel supergroup S along with Wolbachia from the pseudoscorpion Cordylochernes scorpioides ( w Csco), most closely related to Wolbachia supergroups C and F. Using target enrichment by hybridization with Wolbachia -specific biotinylated probes to capture large fragments of Wolbachia DNA, we produced two draft genomes of w Apol. Annotation of w Apol highlights presence of a biotin operon, which is incomplete in many sequenced Wolbachia genomes. Conclusions The present study highlights at least two symbiont acquisition events among pseudoscorpion species. Phylogenomic analysis indicates that the Wolbachia from Atemnus politus ( w Apol), forms a separate supergroup ("S") with the Wolbachia from Cordylochernes scorpioides (w Csco). Interestingly, the biotin operon, present in w Apol, appears to have been horizontally transferred multiple times along Wolbachia evolutionary history.

Abstract
Background: Rice is an important human staple food vulnerable to heavy metal contamination due to its unique physiology and growth environment. High yield with low heavy metal contamination is a common but highly challenging goal for rice breeders worldwide due to lack of genetic knowledge. To identify candidate QTLs for rice yield and heavy metal content, sixteen ionomic traits and thirteen agronomic traits of the USDA Rice mini-core collection were analyzed using both univariate and multivariate GWAS methods in this study. The USDA Rice Mini-Core Collection contains about 1% of the whole Rice Collection of the National Small Grains Collection (NSGC), USA.Results: Using the p-value <1.53×10-8, this criterium p-value was determined by the Bonferroni correction for p-value of 0.05, 106, 47, and 97 QTLs were identified for ionomics in flooded environment, unflooded environment, and agronomic traits, respectively. A large number of QTLs coincide well with previous report results while many of the QTLs are new QTLs, suggesting the efficiency of GWAS methods and the reliability of this study. Our results further showed that each of the four GWAS methods can identify unique as well as common QTLs. When univariate methods failed to identify QTLs for a trait, the multivariate methods frequently detected QTLs. However, when many QTLs were detected by univariate methods, the number of QTLs detected by multivariate methods were reduced in many cases. These analyses suggest that using multiple GWAS methods can complement each other in QTL identification. In addition, several candidate genes involved in ionomic and agronomic traits control were identified by analyzing the sequences of the candidate QTL regions.Conclusions: Significant QTLs for heavy metal, mineral, and agronomic traits are presented in the rice genome and some of them have been fine mapped in the rice genome in this study. This research provides novel insights into the genetic basis of both ionomic and agronomic variations in rice, establishing an important foundation for further studies on reducing heavy-metal contamination and improving crop yields. In addition, the comparison analysis of the GAWS methods showed that each method has unique feature and different method can complement each other.

Abstract
Background: Trichomoniasis resulting from Trichomonas vaginalis (T. vaginalis) has been considered as a commonly seen disease with the transmission way of sex. At present, the detection methods of T. vaginalis mainly include wet mount microscopy, culture, PCR, immunofluorescence and ELISA. However, all of these detection methods exist shortcomings. Methods: In this study, a loop-mediated isothermal amplification (LAMP) assay that targeted the species-specific sequence of adhesion protein 65 (AP65) gene had been conducted to detect T. vaginalis. The optimum reaction system and conditions were optimized in this rapid detection method. Results: The results of sensitivity analysis showed that the LAMP assay targeting the AP65 gene was 1000 times more sensitive than the nested PCR targeting the actin gene commonly used for detection of T. vaginalis, and the detecting limitation of the former was 10 trichomonad. Moreover, the amplification of the target gene AP65 by LAMP assay exhibited high specificity and the product was exclusively from T. vaginalis. The detection technique of LAMP did not exhibit cross-reactivity with the common pathogens of Trichinella spiralis, Toxoplasma gondii, Escherichia coli, Candida albicans, Staphylococcus aureus, Haemophilus. Conclusions: According to the present study, the LAMP assay with the target of AP65 gene, was suitable for the early diagnosis of T. vaginalis infections. Consequently, the LAMP assay was proposed by the current study as a point-of-care examination and an alternative molecular tool which exhibited the potential value in the treatment, control and prevention of trichomoniasis transmission and relevant complication.

Abstract
Hydroxychloroquine sulfate is one of a large series of 4-aminoquinolines with antimalarial activity. Moreover, it is used for the treatment of rheumatoid arthritis. Sometimes Hydroxychloroquine sulfate is very effective for the treatment of autoimmune diseases. Based on the recent clinical experiments it is exploiting for the treatment of COVID-19, corona virus across the globe. A Reverse phase RP-HPLC method have been developed and validated as per the current ICH guidelines for estimation of Hydroxychloroquine sulfate tablets. As part of method validation specificity, linearity, precision and recovery parameters were verified. The concentration and area relationships were linear (R2 > 0.999), over the concentration range of 25 to 300 µg mL-1 for HCQ. The relative standard deviations for precision and intermediate precision were less than 1.5%. The proposed RP-HPLC generic method was applied successfully for evaluation of invitro dissolution profile with different pH conditions like 0.1N HCl, pH 4.5 Acetate buffer and pH 6.8 Phosphate buffers of US marketed reference product.

Published: May 2020

Abstract
Background: Lung cancer (LC) remains the deadliest form of cancer globally. While surgery remains the optimal treatment strategy for individuals with early-stage LC, what the metabolic consequences are of such surgical intervention remains uncertain. Methods: Negative enrichment-fluorescence in situ hybridization (NE-FISH) was used in an effort to detect circulating tumor cells (CTCs) in pre- and post-surgery peripheral blood samples from 51 LC patients. In addition, targeted metabolomics analyses, multivariate statistical analyses, and pathway analyses were used to explore surgery-associated metabolic changes. Results: LC patients had significantly higher CTC counts relative to healthy controls with 66.67% of LC patients having at least 1 detected CTC before surgery. CTC counts were associated with clinical outcomes following surgery. In a targeted metabolomics analysis, we detected 34 amino acids, 147 lipids, and 24 fatty acids. When comparing LC patients before and after surgery to control patients, metabolic shifts were detected via PLS-DA and pathway analysis. Further surgery-associated metabolic changes were identified when comparing LA (LC patients after surgery) and LB (LC patients before surgery) groups. We identified SM 42:4, Ser, Sar, Gln, and LPC 18:0 for inclusion in a biomarker panel for early-stage LC detection based upon an AUC of 0.965 (95% CI = 0.900–1.000). This analysis revealed that SM 42:2, SM 35:1, PC (16:0/14:0), PC (14:0/16:1), Cer (d18:1/24:1), and SM 38:3 may offer diagnostic and prognostic benefits in LC. Conclusions: These findings suggest that CTC detection and plasma metabolite profiling may be an effective means of diagnosing early-stage LC and identifying patients at risk for disease recurrence.

Abstract
Background: No standardized protocol has been suggested in the treatment of postoperative osteomyelitis following fracture fixation. Our team evaluates the clinical efficacy of the modified algorithm for managing postoperative osteomyelitis following fracture fixation with Cierny-Mader type. Methods: 95wounds were reviewed from March 2009 to February 2016 in our hospital. 61 wounds were treated by the modified algorithm as following： Stable hardware + bone not healed Cierny–Mader 1 type = remove hardware, temporary stabilize; Stable hardware + bone not healed Cierny–Mader 2 type = retain hardware ; Stable hardware + bone not healed Cierny–Mader for type 3 and type 4 = remove hardware, temporary stabilize/ Ilizarov technique; Unstable hardware + bone not healed = remove hardware, temporary stabilize/ Ilizarov technique; Stable hardware + bone healed = remove hardware. 34 wounds were treated by the conventional algorithm. Autodermoplasty, flap transfer, myocutaneous flap and other methods including antibiotic irrigation and drug delivery system were used in wound repair.Results: The patients treated with modified algorithm had a significantly reduced recurrence (P＜0.01) , and increased results of negative bacterial cultures (P＜0.01), but however observed a decrease in the number of retained hardware cases (P＜0.05) . For those treated with tissue reconstruction, there was no significantly (P＞0.05) comparing with the conventional group. Conclusions: The modified algorithm for the postoperative osteomyelitis following fracture fixation according to the stability of the hardware and Cierny-Mader type represent a good clinical efficacy in the management of postoperative osteomyelitis. This procedure is simple and shows promising results, more clinical evidence is needed to confirm the existing findings and optimize the treatment of postoperative osteomyelitis following fracture fixation.

Published: May 2020

Abstract
Background: Work-related musculoskeletal disorders imposes a significant and most often underappreciated burden to the individual, nation, healthcare system, and society as a whole. A preliminary literature search suggests that there are at present no reliable estimates on the total prevalence of work-related musculoskeletal disorders in Ethiopia. Further, in Ethiopia, the cloud of infectious and other non-communicable diseases has led to a lack of attention towards work-related musculoskeletal disorders, empirical under-representation, and possible human capital loss. The objective of this protocol is to present a transparent process for how to review the existing literature on the prevalence rates and determinant factors of work-related musculoskeletal disorders in Ethiopia.Method: The proposed methodology is based on Preferred Reporting Systematic Reviews and Protocols (PRISMA-P) statements on the conduct of systematic review and meta-analysis and the MOOSE guidelines for Meta-analysis and Systematic Reviews of Observational Studies. The electronic databases MEDLINE, PubMed, CINAHL, Science Direct index, SCOPUS, PEDro, PsyINFO, Embase, Ebsco, and Google Scholar will be systematically searched. Besides, the grey literature resources such as databases or websites of dissertations and theses will be searched. The reference list of screened articles will also be hand searched. All observational studies reporting on the prevalence of work-related musculoskeletal pain of any bodily region among adult Ethiopians will be included. Random and quality effects models will be used to calculate pooled prevalence with a 95 % confidence interval. Subgroup and sensitivity analyses will be performed. Publication bias and heterogeneity between the included studies will also be assessed and reported.Discussion: The proposed systematic review and meta-analysis will provide valid insight into the pooled prevalence of multi-regional work-related musculoskeletal pain and factors associated. The consensus of data from this review will surely help the policymakers in occupational health and health care sectors in identifying priority areas for interventions in work-related musculoskeletal disorders and will also serve as a baseline for the decision-making processes of musculoskeletal health promotion, work exposure implementations, and prevention programs in workplaces.
