Background: We aimed to evaluate the cost-effectiveness of risk-based strategies to improve the selection of surgically treated stage II colon cancer (CC) patients for adjuvant chemotherapy. Methods: Using the ‘Personalized Adjuvant TreaTment in EaRly stage coloN cancer’ (PATTERN) model, we evaluated five selection strategies: (1) no chemotherapy, (2) Dutch guideline recommendations assuming observed adherence, (3) Dutch guideline recommendations assuming perfect adherence, (4) biomarker mutation OR pT4 stage strategy in which patients with MSS status combined with a pT4 stage or a mutation in BRAF and/or KRAS receive chemotherapy assuming perfect adherence and (5) biomarker mutation AND pT4 stage strategy in which patients with MSS status combined with a pT4 stage tumor and a BRAF and/or KRAS mutation receive chemotherapy assuming perfect adherence. Outcomes were number of CC deaths per 1000 patients and total discounted costs and quality-adjusted life-years (QALYs) per patient (pp). Analyses were conducted from a societal perspective. The robustness of model predictions was assessed in sensitivity analyses. Results: The reference strategy, that is, no adjuvant chemotherapy, resulted in 139 CC deaths in a cohort of 1000 patients, 8.077 QALYs pp and total costs of €22,032 pp. Strategies 2–5 were more effective (range 8.094–8.217 QALYs pp and range 118–136 CC deaths per 1000 patients) and more costly (range €22,404–€25,102 pp). Given a threshold of €50,000/QALY, the optimal use of resources would be to treat patients with either the full adherence strategy and biomarker mutation OR pT4 stage strategy. Conclusion: Selection of stage II CC patients for chemotherapy can be improved by either including biomarker status in the selection strategy or by improving adherence to the Dutch guideline recommendations.

Objective: To assess the level of preparedness of health professionals working in South Gondar Zone public hospital, Debre Tabor Comprehensive specialized Hospital for coronavirus. Methods: An institutional-based cross-sectional survey was conducted with a self-administered questionnaire from April 20 to May 20. Descriptive statistics, chi-square test, bivariable, and multivariable logistic analysis were done. Bivariable and multivariable regression was held to determine significant predictors for preparedness. For all statistical analyses, a p value ⩽ 0.05 was considered as significant. Results: From a total health professionals, 301 health professionals with a response rate of 86% participated in the study. Among these, 206 were males while 95 participants were females with a mean age of 29.71 ± 5.84 years. To determine the preparedness level, we use the mean preparedness score of the respondents. Around 64.1% of health professionals were well prepared. Among 20 respondents who had a chronic illness, 80% of them think their illness is risky for the pandemic. The majority of the respondents (229/76.1%) responded as they were working without protective equipment. From the multivariable analysis male sex (adjusted odds ratio = 2.07, 95% confidence interval = 1.193–3.590), family living with them (adjusted odds ratio = 4.507, 95% confidence interval = 1.863–10.90), and involvement of other previous outbreak (adjusted odds ratio = 2.245, 95% confidence interval = 1.176–4.286) were the predictors for good preparedness. Conclusion: Most of the health professionals were well prepared. Being male, living within a family, and involvement of other outbreaks leads to good preparation. Governmental bodies and hospital managers have to help health professionals to be prepared enough to combat the pandemic.
Utilizing the care coordination Atlas as a framework: An integrative review of transitional care models
Authors: Chakurian Daphne , Popejoy Lori 
Published: March 2021

Introduction Care coordination reduces care fragmentation and costs while improving health care quality. Transitional care programs, guided by tested models are an important component of effective care coordination, and have been found to reduce adverse events and prevent hospital readmissions. Using the Care Coordination Atlas as a framework, this article reports an integrative review of two transitional care models including analysis of model components, implementation factors, and associated 30-day all-cause hospital readmission rates. Methods Integrative review methodology. PubMed and Scopus databases were searched from January 2015 to July 2020. Fourteen studies set in 18 skilled nursing facilities and 50 hospitals were selected for data extraction and analysis. Results The ReEngineered Discharge model had five components and the Better Outcomes by Optimizing Safe Transitions model had eight components in the nine Care Coordination Atlas domains. Communication dominated activities in both models while neither addressed accountability/responsibility. Implementation was influenced by leadership commitment to understanding complexity of the models, culture change, integration of models into workflows, and associated labor costs. Model implementation studies consistently reported improvements in facilities’ 30-day all-cause hospital readmission rates. Discussion The Care Coordination Atlas was a useful framework to guide analysis of transitional care models. Leadership commitment to and participation in model implementation is vital. The models do not focus beyond the immediate post-discharge period limiting the impact on chronic disease management. Frameworks such as the Care Coordination Atlas are useful to help guide development of care coordination activities and associations with readmission rates.
Partial Single Stage Exchange Arthroplasty With Retention of a Well Fixed Cemented Femoral Stem for the Treatment of Culture Negative Infection in a Bipolar Hemiarthroplasty: A Case Report
Authors: Mencia Marlon M. , Cawich Shamir O. , Sandiford Nemandra 
Published: March 2021

Background: Prosthetic joint infection (PJI) is the second most common cause for revision following hip hemiarthroplasty (HHA) resulting in a mortality rate of 5.6%. The treatment of PJI is both challenging and controversial, without general consensus on best practice. In an attempt to avoid surgery, patients are commonly prescribed antibiotics, reducing the chance of detecting a microorganism, and culture negative infections are reported to occur in up to 21% of all PJI. Two stage revision is arguably the gold standard treatment but frequently these patients are too frail to undergo such extensive procedures. Some surgeons have attempted to avoid this by leaving well fixed implants undisturbed, effectively performing a partial single-stage revision. Case Presentation: A previously well 83 -year-old female patient presented with a gradual onset of increasing pain and difficulty walking. Just over 1 year prior to this presentation she fell at home and underwent an uncomplicated bipolar hemiarthroplasty. Clinical examination as well as serological and radiological investigations were suspicious for a periprosthetic infection. Her rapidly deteriorating clinical picture required prompt surgical intervention. In theater the patient underwent a single stage partial exchange arthroplasty leaving the well cemented femoral stem undisturbed. Although multiple samples were taken, no microorganism was identified. The patient has been followed up for 1 year and remains well, with no recurrence of infection. Her inflammatory markers have returned to normal and radiographs demonstrate no evidence of loosening of the total hip replacement. Conclusion: The burden of infection following hip hemiarthroplasty is likely to parallel the predicted increase in hip fractures. The combination of physiologic frailty, osteoporosis and multiple medical comorbidities are pertinent factors for consideration in the development of a treatment strategy. A partial single stage revision THR performed by an experienced arthroplasty surgeon, along with expertly led antimicrobial therapy may be considered in carefully selected patients.

Published: March 2021

Introduction: Pneumonia, thromboembolic and ischemic events, urinary tract infections (UTI), delirium and acute kidney injury (AKI) are common complications during the treatment of fragility fractures. In a 2 years-follow-up we determined the according incidence and risk factors of these and other complications in orthogeriatric inward patients, as well as the respective associated mortality. Methods: All patients treated on an orthogeriatric co-managed ward over the course of a year were included. Besides injury, therapy and geriatric assessment parameters, we evaluated the inward incidence of common complications. In a 2 years-follow-up the associated death rates were aquired. SPSS (IBM) was used to determine the importance of risk factors predisposing to the respective occurrence of a complication and accordingly determine it’s impact on the patients’ 1- and 2-years-mortality. Results: 830 orthogeriatric patients were initially assessed with a remaining follow-up cohort of 661 (79.6%). We observed very few cases of thrombosis (0.6%), pulmonary embolism (0.5%), apoplex (0.5%) and myocardial infarction (0.8%). Pneumonia was seen in 42 (5.1%), UTI in 85 (10.2%), delirium in 186 (22.4%) and AKI in 91 (11.0%) patients. Consistently ADL on admission was found to be a relevant risk factor in the development of each complication. After adjustment only AKI showed a significant increased mortality risk of 1.60 (95%CI:1.086-2.350). Discussion: In our fracture-independent assessment of complications in the orthogeriatric treatment of inward patients we’ve seen very rare cases of cardiac and thrombotic complications. Typical fragility-fracture associated common events like pneumonia, UTI, delirium and AKI were still more incidental. No complication except AKI was associated to significant increased mortality risk. Conclusions: The relevance of orthogeriatric care in prevention and outcome of inward complications seems promising, needing still more controlled studies, evaluating not just hip fracture patients but more diverse groups. Consensus is needed in the scholar evaluation of orthogeriatric complications.

Authors: Li Wei-Shang , Cai Yun-Fei , Cong Lin 
Published: March 2021

Study Design: Meta-analysis. Objective: To systematically compare the effectiveness and safety of vertebral augmentation procedure (VAP) with non-surgical management (NSM) for the treatment of osteoporotic vertebrate compression fractures (OVCFs). Methods: Systematic reviews and meta-analyses with the comparison between VAP and NSM were identified to extract randomized controlled trials from electronic database. Additionally, recently published RCTs were identified. Two researchers independently extracted the data. The primary outcome of this meta-analysis was pain relief evaluated by visual analogue scale (VAS). Results: Twenty RCTs involving 2566 patients with painful OVCFs were included. Significant differences were found between percutaneous vertebroplasty (PVP) and conservative treatment (CT) in VAS at each time point during follow-up period. The differences of VAS were not significant between PVP and sham procedure at most time points during follow-up period. In subgroup analysis based on fracture type and fracture location, significant differences of VAS were found between PVP and CT and were not found between PVP and sham procedure. In subgroup analysis of duration of back pain, significant differences were found between PVP and CT in VAS at 1 week, 3 month and 1 year. And the differences of VAS were not significant between PVP and CT at 1 month and 6 month. Conclusion: BKP is considered sufficient to achieve good clinical outcomes. PVP is associated with on beneficial effect on treatment of painful OVCFs compared with sham procedure. The indication and timing of VAP need further research. More independently high-quality RCTs with sufficiently large sample sizes reporting cost-effectiveness are needed.

Published: March 2021

Background: Changes in atmospheric pressure are suggested to trigger headaches. This pilot study was made to determine craniofacial sensations accompanying short phases of changing barometric pressure. Methods: In a crossover design, 15 adult healthy subjects were exposed in a climate chamber to 8 min phases of barometric pressure lowering by 0, 20 and 40 hPa. The subjects rated their sensations of ear pressure, head compression and the occurrence of headache every minute on a visual analogue scale (VAS, range 0–10). Pulse rate was recorded as a parameter for autonomic functions. Results: Nearly all subjects experienced ear pressure and half of them compression of their head at variable degrees. These sensations started in most subjects during the phase of lowering barometric pressure and increased to an average rating of about 3 VAS when returning to ambient atmospheric pressure. Heart rate slightly decreased during this phase. Three subjects reported mild to moderate headache for various durations within these phases. Conclusions: Changes in barometric pressure can be associated with sensations of ear pressure and head compression and may trigger headaches. The generation of these sensations is discussed with regard to convergent trigeminal innervation of the ear, the paranasal sinuses and the cranial meninges.

AbstractBackgroundThe asthma-related airway wall remodeling is associated i.a. with a damage of bronchial epithelium and subepithelial fibrosis. Functional interactions between human bronchial epithelial cells and human bronchial fibroblasts are known as the epithelial-mesenchymal trophic unit (EMTU) and are necessary for a proper functioning of lung tissue. However, a high concentration of the transforming growth factor-β1(TGF-β1) in the asthmatic bronchi drives the structural disintegrity of epithelium with the epithelial-to-mesenchymal transition (EMT) of the bronchial epithelial cells, and of subepithelial fibrosis with the fibroblast-to-myofibroblast transition (FMT) of the bronchial fibroblasts. Since previous reports indicate different intrinsic properties of the human bronchial epithelial cells and human bronchial fibroblasts which affect their EMT/FMT potential beetween cells derived from asthmatic and non-asthmatic patients, cultured separatelly in vitro, we were interested to see whether corresponding effects could be obtained in a co-culture of the bronchial epithelial cells and bronchial fibroblasts. In this study, we investigate the effects of the TGF-β1on the EMT markers of the bronchial epithelial cells cultured in the air-liquid-interface and effectiveness of FMT in the bronchial fibroblast populations in the EMTU models.ResultsOur results show that the asthmatic co-cultures are more sensitive to the TGF-β1than the non-asthmatic ones, which is associated with a higher potential of the asthmatic bronchial cells for a profibrotic response, analogously to be observed in '2D' cultures. They also indicate a noticeable impact of human bronchial epithelial cells on the TGF-β1-induced FMT, stronger in the asthmatic bronchial fibroblast populations in comparison to the non-asthmatic ones. Moreover, our results suggest the protective effects of fibroblasts on the structure of the TGF-β1–exposed mucociliary differentiated bronchial epithelial cells and their EMT potential.ConclusionsOur data are the first to demonstrate a protective effect of the human bronchial fibroblasts on the properties of the human bronchial epithelial cells, which suggests that intrinsic properties of not only epithelium but also subepithelial fibroblasts affect a proper condition and function of the EMTU in both normal and asthmatic individuals.

Abstract
Background
Low temperature (LT) often occurs at the seedling stage in the early rice-growing season, especially for direct seeded early-season indica rice, and using flooding irrigation can mitigate LT damage in rice seedlings. The molecular mechanism by which flooding mitigates the damage induced by LT stress has not been fully elucidated. Thus, LT stress at 8 °C, LT accompanied by flooding (LTF) and CK (control) treatments were established for 3 days to determine the transcriptomic, proteomic and physiological response in direct seeded rice seedlings at the seedling stage.

Results
LT damaged chloroplasts, and thylakoid lamellae, and increased osmiophilic bodies and starch grains compared to CK, but LTF alleviated the damage to chloroplast structure caused by LT. The physiological characteristics of treated plants showed that compared with LT, LTF significantly increased the contents of rubisco, chlorophyll, PEPCK, ATP and GA3 but significantly decreased soluble protein, MDA and ABA contents. 4D-label-free quantitative proteomic profiling showed that photosynthesis-responsive proteins, such as phytochrome, as well as chlorophyll and the tricarboxylic acid cycle were significantly downregulated in LT/CK and LTF/CK comparison groups. However, compared with LT, phytochrome, chlorophyllide oxygenase activity and the glucan branching enzyme in LTF were significantly upregulated in rice leaves. Transcriptomic and proteomic studies identified 72,818 transcripts and 5639 proteins, and 4983 genes that were identified at both the transcriptome and proteome levels. Differentially expressed genes (DEGs) and differentially expressed proteins (DEPs) were significantly enriched in glycine, serine and threonine metabolism, biosynthesis of secondary metabolites, glycolysis/gluconeogenesis and metabolic pathways.

Conclusion
Through transcriptomic, proteomic and physiological analyses, we determined that a variety of metabolic pathway changes were induced by LT and LTF. GO and KEGG enrichment analyses demonstrated that DEGs and DEPs were associated with photosynthesis pathways, antioxidant enzymes and energy metabolism pathway-related proteins. Our study provided new insights for efforts to reduce the damage to direct seeded rice caused by low-temperature stress and provided a breeding target for low temperature flooding-resistant cultivars. Further analysis of translational regulation and metabolites may help to elucidate the molecular mechanisms by which flooding mitigates low-temperature stress in direct seeded early indica rice at the seedling stage.

Published: March 2021

Abstract
Background
Oxford Nanopore Technologies’ instruments can sequence reads of great length. Long reads improve sequence assemblies by unambiguously spanning repetitive elements of the genome. Sequencing reads of significant length requires the preservation of long DNA template molecules through library preparation by pipetting reagents as slowly as possible to minimize shearing. This process is time-consuming and inconsistent at preserving read length as even small changes in volumetric flow rate can result in template shearing.

Results
We have designed SNAILS (Slow Nucleic Acid Instrument for Long Sequences), a 3D-printable instrument that automates slow pipetting of reagents used in long read library preparation for Oxford Nanopore sequencing. Across six sequencing libraries, SNAILS preserved more reads exceeding 100 kilobases in length and increased its libraries’ average read length over manual slow pipetting.

Conclusions
SNAILS is a low-cost, easily deployable solution for improving sequencing projects that require reads of significant length. By automating the slow pipetting of library preparation reagents, SNAILS increases the consistency and throughput of long read Nanopore sequencing.

Abstract
Background
Hispidin (HIP) and its derivatives, a class of natural fungal metabolites, possess complex chemical structures with extensive pharmacological activities. Phellinus igniarius, the most common source of HIP, can be used as both medicine and food. However, the biosynthetic pathway of HIP in P. igniarius remains unclear and we have a limited understanding of the regulatory mechanisms related to HIP. In this work, we sought to illustrate a biosynthesis system for hispidin and its derivatives at the protein level.

Results
We found that tricetolatone (TL) is a key biosynthetic precursor in the biosynthetic pathway of hispidin and that its addition led to increased production of hispidin and various hispidin derivatives. Based on the changes in the concentrations of precursors and intermediates, key timepoints in the biosynthetic process were identified. We used isobaric tags for relative and absolute quantification (iTRAQ) to study dynamic changes of related proteins in vitro. The 270 differentially expressed proteins were determined by GO enrichment analysis to be primarily related to energy metabolism, oxidative phosphorylation, and environmental stress responses after TL supplementation. The differentially expressed proteins were related to ATP synthase, NAD binding protein, oxidoreductase, and other elements associated with electron transfer and dehydrogenation reactions during the biosynthesis of hispidin and its derivatives. Multiple reaction monitoring (MRM) technology was used to selectively verify the iTRAQ results, leading us to screen 11 proteins that were predicted to be related to the biosynthesis pathways.

Conclution
These findings help to clarify the molecular mechanism of biosynthesis of hispidin and its derivatives and may serve as a foundation for future strategies to identify new hispidin derivatives.
