Abstract
INTRODUCTION Elvitegravir/cobicistat/emtricitabine/tenofovir alafenamide (E/C/F/TAF) has been increasingly replaced by bictegravir/emtricitabine/tenofovir alafenamide (B/F/TAF) in the treatment of human immunodeficiency virus (HIV) owing to its more favorable pharmacokinetics and fewer drug-drug interactions. However, the effect of this switch on plasma lipids and lipidomic profiles remains poorly characterized. METHODS HIV infected patients on an E/C/F/TAF regimen were recruited into the study and followed up every 12 weeks. Participants were divided into E/C/F/TAF and B/F/TAF groups depending on whether they were switched to B/F/TAF during follow-up. Clinical information and blood samples were collected at 0, 12, and 24 weeks, and lipidomic analysis was performed using liquid chromatography mass spectrometry. RESULTS No significant differences were observed between the groups at baseline. At week 24, patients switched to B/F/TAF had lower triglyceride [mmol/L; 1.23 (0.62) versus 2.03 (0.75), P = 0.001] and very low-density lipoprotein cholesterol [mmol/L; 0.64 (0.26) versus 0.84 (0.32), P = 0.037) compared with patients who continued E/C/F/TAF therapy. Small decrease from baseline in Framingham general cardiovascular risk score (FRS) was observed in the B/F/TAF arm [week (W) 0: 2.59 (1.57) versus W24: 2.18 (1.01), P = 0.043]. Lipidomic analysis indicated that E/C/F/TAF treatment increased the levels of several diglycerides (DGs), triacylglycerols (TAGs), and lyso-phosphatidylcholines (LPCs), whereas switching to B/F/TAF led to increased sphingolipids and glycerophospholipids. After adjusting for demographic and clinical parameters, only DG (16:0/18:2), DG (18:2/22:6), DG (18:3/18:2), DG (20:5/18:2), TAG (18:3/18:2/21:5), TAG (20:5/18:2/22:6), and LPC (22:6) were found to be significantly associated with FRS (regression coefficient of 0.17-6.02, P < 0.05). Most of these FRS associate lipid species were significantly elevated in individuals treated with E/C/F/TAF instead of individuals treated with B/F/TAF. CONCLUSION E/C/F/TAF promotes the accumulation of lipid species closely associated with cardiovascular disease (CVD) risk among people living with HIV, whereas B/F/TAF has a decreased impact on CVD-related lipid profile and is associated with lower CVD risk.

Abstract
Acute lung injury (ALI) is an inflammatory disease associated with alveolar injury, subsequent macrophage activation, inflammatory cell infiltration, and cytokine production. Mesenchymal stem cells (MSCs) are beneficial for application in the treatment of inflammatory diseases due to their immunomodulatory effects. However, the mechanisms of regulatory effects by MSCs on macrophages in ALI need more in-depth study. Lung tissues were collected from mice for mouse lung organoid construction. Alveolar macrophages (AMs) derived from bronchoalveolar lavage and interstitial macrophages (IMs) derived from lung tissue were co-cultured, with novel matrigel-spreading lung organoids to construct an in vitro model of lung organoids-immune cells. Mouse compact bone-derived MSCs were co-cultured with organoids-macrophages to confirm their therapeutic effect on acute lung injury. Changes in transcriptome expression profile were analyzed by RNA sequencing. Well-established lung organoids expressed various lung cell type-specific markers. Lung organoids grown on spreading matrigel had the property of functional cells growing outside the lumen. Lipopolysaccharide (LPS)-induced injury promoted macrophage chemotaxis toward lung organoids and enhanced the expression of inflammation-associated genes in inflammation-injured lung organoids-macrophages compared with controls. Treatment with MSCs inhibited the injury progress and reduced the levels of inflammatory components. Furthermore, through the nuclear factor-κB pathway, MSC treatment inhibited inflammatory and phenotypic transformation of AMs and modulated the antigen-presenting function of IMs, thereby affecting the inflammatory phenotype of lung organoids. Lung organoids grown by spreading matrigel facilitate the reception of external stimuli and the construction of in vitro models containing immune cells, which is a potential novel model for disease research. MSCs exert protective effects against lung injury by regulating different functions of AMs and IMs in the lung, indicating a potential mechanism for therapeutic intervention.

Abstract
Background The significance of hepatitis B virus (HBV) in cerebrospinal fluid (CSF) is unclear. Methods Synchronous serum and CSF samples were collected from 13 patients. HBV DNA, full-length genome, quasispecies, phylogenetic tree, compartmentalization and mutation of the reverse transcriptase (RT) region were performed based on PCR and sequencing methods. Results HBV DNA was detected in the CSF of 3 antiviral-naïve individuals and 1 individual after successful antiviral therapy. Complete full-length HBV genomes were isolated from the CSF of 5 individuals, including 2 with undetectable serum HBV DNA. Ten individuals exhibited distinct CSF-serum quasispecies, 8 harbored independent CSF-serum genetic compartmentalization and phylogenetic trees, and 5 lamivudine/entecavir-associated resistance mutations only in the CSF. The frequencies of rtL180M and rtM204I/V mutations in both serum and CSF were higher in HIV-HBV-coinfected individuals than in the HBV-monoinfected ones (serum: rtL180M: 3.9% vs. 0, P = 0.004; rtM204I/V: 21.3% vs. 0, P < 0.001; CSF: rtL180M: 7.6% vs. 0, P = 0.026; rtM204I/V 7.6% vs. 1.6%, P = 0.097). Conclusion CSF is a potential HBV reservoir, and HBV in CSF harbors distinct evolution and mutation characteristics from those in serum. HIV infection increases the possibility of HBV rtL180M and rtM204I/V mutations in both serum and CSF.

Abstract
BACKGROUND Mesenchymal stem cell (MSC) treatment plays a major role in the management of acute lung injury (ALI), and neutrophils are the initial line of defense against ALI. However, the effect of MSCs on neutrophils in ALI remains mostly unknown. METHODS We investigated the characteristics of neutrophils in lung tissue of ALI mice induced by lipopolysaccharide after treatment with MSCs using single-cell RNA sequencing. Neutrophils separated from lung tissue in ALI were co-cultured with MSCs, and then samples were collected for reverse transcription-polymerase chain reaction and flow cytometry. RESULTS During inflammation, six clusters of neutrophils were identified, annotated as activated, aged, and circulatory neutrophils. Activated neutrophils had higher chemotaxis, reactive oxygen species (ROS) production, and nicotinamide adenine dinucleotide phosphate (NADPH) oxidase scores than aged neutrophils. Circulatory neutrophils occurred mainly in healthy tissue and were characterized by higher expression of Cxcr2 and Sell. Activated neutrophils tended to exhibit higher expression of Cxcl10 and Cd47, and lower expression of Cd24a, while aged neutrophils expressed a lower level of Cd47 and higher level of Cd24a. MSC treatment shifted activated neutrophils toward an aged neutrophil phenotype by upregulating the expression of CD24, thereby inhibiting inflammation by reducing chemotaxis, ROS production, and NADPH oxidase. CONCLUSION We identified the immunosuppressive effects of MSCs on the subtype distribution of neutrophils and provided new insight into the therapeutic mechanism of MSC treatment in ALI.

Abstract
Abstract
Background
Workplace health promotion (WHP) is effective when it is implemented in a high-quality and sustainable manner. Companies in the Austrian quality management system can apply for a WHP quality certificate every three years. More and more companies are integrating WHP into their regular operations. This work investigates the WHP quality system and how the companies develop over time.
Methods
WHP quality is measured using 15 holistic quality criteria, which are assessed by an external, independent institute. For the period 2014-2021, evaluations from n = 570 companies with two and from n = 278 companies over three measurement points in time are available (initial and renewal awards). The (potential) change of the WHP quality is examined with a longitudinal design by the means of confirmatory factor analyses and autoregressive models with latent variables.
Results
The measurement of WHP quality shows acceptable to good measurement accuracy (internal consistency-reliability: α = 0.85-0.89), validity (convergent and discriminant validity) and metric measurement invariance over time. At structural level, relative stability of WHP quality can be demonstrated for the measurement points (β = 0.40-0.52, p < 0.001). Both the quality of WHP and the temporal stability differentiate significantly according to the firm size and the experience of the company with WHP structures and processes.
Conclusions
The use of the criteria allows a reliable, valid and objective quality assessment of WHP quality due to the concept of the assessment process. WHP quality is a relatively stable characteristic of the company, which, however, varies according to temporal, structural and process-related aspects. Company size moderates to a lesser extent of quality changes over time. This is in line with expectations, but also indicates that small companies should be clearly motivated and supported for their WHP measures. The insights help to further develop quality assurance in WHP and public health.
Key messages
• The criteria used allow a reliable, valid and objective assessment of WHP quality.
• Because firm size moderates the change in WHP quality, small firms should be continuously encouraged and supported.

Abstract
Purpose Cognitive impairment associated with human immunodeficiency virus (HIV)-related cryptococcal meningitis (HCM) in the context of immune reconstitution inflammatory syndrome is difficult to address. This study was a follow-up of lenalidomide treatment outcomes in patients with HCM and cognitive impairment after complete cryptococcal clearance. Patients and Methods Seven HCM patients with neuroinflammation and cognitive impairment after complete cryptococcal clearance were enrolled in this prospective study. Neurocognitive assessment, clinical examination and cerebrospinal fluid (CSF) assays were performed before and after lenalidomide treatment. Results After lenalidomide treatment, the Montreal Cognitive Assessment [week (W) 0 (median [interquartile range]: 23.0 (13.0–24.0) vs W24: 26.0 (24.0–28.00), P=0.018] and International HIV Dementia Scale scores [W0: 9.0 (2.5–10.5) vs W24: 11.0 (10.00–12.0), P=0.028] improved significantly, mainly in the domain of memory function. There was no significant difference in the Center for Epidemiological Research Depression scores for anxiety and depression before and after treatment. Further stratified analyses revealed that the patients with cognitive improvement group had higher levels of CSF white blood cells [94.0 (44.0–180.0) vs 0 (0–1.5), P=0.032], CSF protein [4.9 (3.0–6.6) vs 0.6 (0.5–0.7), P=0.034], CSF albumin [318.5 (190.9–346.5) vs 33.5 (30.4–46.2), P=0.034], and CSF IgG [160.5 (73.8–256. 0) vs 4.7 (4.3–7.4), P=0.034] but a lower CSF glucose level [2.4 (2.0–2.7) vs 2.8 (2.8–3.9), P=0.032] than the patients with cognitive non-improvement group before treatment. CSF inflammatory cytokines of the growth-related oncogene, interleukin [IL]-10, granulocyte-colony stimulating factor, IL-6, IL-8, complement factor H, tumor necrosis factor-α, and α-2 macroglobulin were obviously decreased in patients with cognitive improvement group after lenalidomide treatment. Conclusion Lenalidomide potentially reduces cognitive impairment caused by immune reconstitution inflammatory syndrome in patients with HCM after cryptococcal clearance by inhibiting intracranial inflammation.

Abstract
Cryptococcal meningitis (CM) is a common opportunistic infection in patients with acquired immune deficiency syndrome. Although there is a standardized treatment for CM, some patients still have CM-associated immune reconstitution inflammatory syndrome (IRIS) after anti-cryptococcal and antiretroviral therapy, which manifests as cognitive impairment. We report two cases of CM-associated IRIS in human immunodeficiency virus (HIV) patients that were treated with lenalidomide. The treatment yielded a rapid clinical remission and improved cognitive function in both patients; their Montreal Cognitive Assessment (MoCA) and International HIV Dementia Scale (IHDS) scores improved. Furthermore, we evaluated changes in 32 cytokines in the cerebrospinal fluid of two patients and found that both MoCA and IHDS were significantly negatively correlated with inflammation-related factors (growth-related oncogene, interleukin [IL]-10, IL-2, IL-8, macrophage inflammatory protein-1β, tumor necrosis factor [TNF]-α) and significantly positively correlated with dementia-related factors (αβ42 and total tau). Our study reveals the potential of lenalidomide in treating cognitive impairment caused by immune-mediated inflammation in patients with HIV-CM. Moreover, we speculate that lenalidomide improves cognitive function by regulating intracranial inflammation via multiple pathways, not only by TNF-α blocking.

Abstract
Background: Streptococcus suis has been recognized as a zoonotic pathogen that may cause infections in humans. Although rarely described, it is not surprising that both cryptococcal and streptococcus suis meningitis infections can co-exist in a HIV-infected patient with a low CD4 count. However, a fast and accurate diagnose of meningitis of multipathogenic infections is challenging. In this report, we describe such a case of a HIV-infected patient with meningitis of multipathogenic infections. Case Presentation: The patient was a 34-year-old Chinese male who was diagnosed with cryptococcal meningitis and HIV at the same time about 1 year ago. During the same time period, he had received (with good compliance) fluconazole and tenofovir-lamivudine- dolutegravir based antiretroviral therapy (ART). However, symptom of progressively worsening occipital headache appeared after he was exposed to a truck which was used for transporting pigs. Initial workup indicated an increase of the cerebrospinal fluid (CSF) opening pressure (OP) and an increase in the number of lymphocytes and proteins in CSF. A magnetic resonance imaging (MRI) scan revealed that partial cerebellar surface enhancement. The cryptococcus capsular antigen test of CSF was positive. The results of the India Ink microscopy for cryptococcus, nucleic acid of CMV and EBV and mycobacterium tuberculosis (MTB) tests of CSF were negative. The results of the bacteria and fungi smear and culture of CSF were also negative. Eventually, streptococcus suis was detected using next-generation sequencing (NGS) in CSF. The diagnosis of Streptococcus suis meningitis was made based on the patient's contact history with carrier pigs and the clinical findings addressed above. The treatment of 2 weeks of intravenous ceftriaxone and 1 week of oral moxifloxacin resulted in improvement of the condition of CSF. The anti-fungal treatment using fluconazole continued until the CFS OP went down to a normal level and the cryptococcus capsular antigen test of CSF was negative 6 months later. Conclusion: This case highlights that NGS might be beneficial to HIV-infected patients who have meningitis with negative CSF culture results. Multiple etiologies for such condition in the immunocompromised patients must be taken into consideration and early stage NGS is recommended.

Abstract
Background: The clinical relevance of single or repeated episodes of Candida spp. in cerebrospinal fluid (CSF) in adult patients is debatable. Methods: Forty-two patients with positive Candida episodes in CSF were enrolled in this retrospective study. Results: A total of 42.9% (18/42) were determined to have probable Candida meningitis (PCM). Neurosurgery [odds ratio (OR) (95% confidence interval), OR: 14.4 (1.6–126.1), P = 0.004], lumbar drainage [OR: 5.8 (1.5–23.3), P = 0.009], VP shunt [(OR: 5.6 (1.2–25.8), P = 0.020)], external ventricular drainage [OR: 4.7 (1.3–17.7), P = 0.018], CRP ≥ 10.0 mg/L [OR: 4.9 (1.3–18.1), P = 0.034], and postsurgical broad-spectrum antibiotics [OR: 9.5 (1.8–50.5), P = 0.004] were risk factors associated with PCM. A single CSF Candida episode for the diagnosis of PCM had 7.7% (0.4–37.9%) sensitivity and 20.7% (8.7–40.3%) specificity, whereas repeated episodes of Candida had 66.7% (41.2–85.6%) sensitivity and 95.8% (76.9–99.8%) specificity. No significant difference was found in radiological imaging or CSF profiles between PCM and non-PCM patients. A total of 37.5% (9/24) of patients without PCM received empirical antifungal treatment, and 88.9% (16/18) of patients with PCM received preemptive antifungal treatment. PCM patients had hospitalized mortality rates of 50.0% (9/18). The odds ratio of mortality was 23.0 (2.5–208.6) for PCM patients compared with non-PCM patients (P = 0.001). Conclusion: Both single and repeated positive CSF samples have low validity for the diagnosis of PCM, suggesting that novel strategies for diagnosis algorithms of PCM are urgently needed. Empirical antifungal treatment should be started immediately for suspicious patients with risk factors.

Abstract
Abstract
Background
Many companies had to switch to teleworking (TW) due to COVID-19 pandemic in spring 2020. However, TW conditions (home office) are not always health promoting. The question was: To what extent companies enabled TW before, during and after the first lockdown (time points t1-t3) and what is the role of workplace health promotion (WHP) in the establishment of health-promoting TW?
Methods
Using TAM, hypotheses were operationalised using a standardised questionnaire. At the beginning of 2020, a selection of 1858 Austrian companies were asked to participate in an online survey. The n = 192 responses from company representatives cover a broad mix of different sectors, industries, company sizes and regions in Austria. The analysis was carried out using structural equation models.
Results
Both the extent of TW implemented (means: mt1=3.7, mt2=18.4, mt3=8.6 days per month/employee) and the proportion of the workforce that could make use of TW (mt1=17.3%, mt2=58.6%, mt3=40.1%) increased significantly during the 1st lockdown and did not return to the pre-lockdown level afterwards. The degree of TW depended on how well the companies were prepared for it (β = 0.271). The (a) experience with TW and the (b) willingness to continue offering TW depended on the preparation (a: 0.243; b: 0.453) and on the actual degree of implementation of TW (a: 0.228; b: 0.193). For the intention to implement health-promoting TW in the company, the general willingness for TW (0.415) but also the existing WHP structures are central requirements (0.446; all p < 0.050).
Conclusions
Far more than before COVID-19, TW is of central interest for public health and WHP. In terms of a holistic health understanding of TW, companies have to adapt to the changing conditions (eg technical, communication) and to establish comprehensive WHP structures and processes. Support for companies can come from training or further education to raise awareness and develop an appropriate health-promoting company culture.
Key messages
Health promoting telework conditions need to be assessed and developed further. Companies need to be supported when implementing health-promoting telework, eg with guidelines, further education.

Abstract
BACKGROUND Knowledge about the 1-year outcome of COVID-19 is limited. The aim of this study was to follow-up and evaluate lung abnormalities on serial computed tomography (CT) scans in patients with COVID-19 after hospital discharge. METHODS A prospective cohort study of patients with COVID-19 from the First Affiliated Hospital, Zhejiang University School of Medicine was conducted, with assessments of chest CT during hospitalization and at 2 weeks, 1 month, 3 months, 6 months, and 1 year after hospital discharge. Risk factors of residual CT opacities and the influence of residual CT abnormalities on pulmonary functions at 1 year were also evaluated. RESULTS A total of 41 patients were followed in this study. Gradual recovery after hospital discharge was confirmed by the serial CT scores. Around 47% of the patients showed residual aberration on pulmonary CT with a median CT score of 0 (interquartile range (IQR) of 0-2) at 1 year after discharge, with ground-glass opacity (GGO) with reticular pattern as the major radiologic pattern. Patients with residual radiological abnormalities were older (p = 0.01), with higher rate in current smokers (p = 0.04), higher rate in hypertensives (p = 0.05), lower SaO2 (p = 0.004), and higher prevalence of secondary bacterial infections during acute phase (p = 0.02). Multiple logistic regression analyses indicated that age was a risk factor associated with residual radiological abnormalities (OR 1.08, 95% CI 1.01-1.15, p = 0.02). Pulmonary functions of total lung capacity (p = 0.008) and residual volume (p < 0.001) were reduced in patients with residual CT abnormalities and were negatively correlated with CT scores. CONCLUSION During 1-year follow-up after discharge, COVID-19 survivors showed continuous improvement on chest CT. However, residual lesions could still be observed and correlated with lung volume parameters. The risk of developing residual CT opacities increases with age.

Abstract
This study aims to comparatively analyze the therapeutic efficacy upon multiple medication plans over lopinavir/ritonavir (LPV/r), arbidol (ARB), and methylprednisolone on patients with coronavirus disease 2019 (COVID‐19). Totally, 75 COVID‐19 patients admitted to The First Affiliated Hospital, Zhejiang University School of Medicine from January 22, 2020 to February 29, 2020 were recruited and grouped based on whether or not LPV/r and ARB were jointly used and whether or not methylprednisolone was used. Indexes including body temperature, time for nucleic acid negative conversion, hospital stays, and laboratory indexes were examined and compared. For all patients, there were no significant differences in the change of body temperature, the time for negative conversion, and hospital stays whether LPV/r and ARB were jointly used or not. While for severe and critically severe patients, methylprednisolone noticeably reduced the time for negative conversion. Meanwhile, the clinical efficacy was superior on patients receiving methylprednisolone within 3 days upon admission, and the duration of hospital stays was much shorter when methylprednisolone was given at a total dose of 0–400 mg than a higher dose of >400 mg if all patients received a similar dose per day. Nonetheless, no significant changes across hepatic, renal, and myocardial function indexes were observed. LPV/r combined with ARB produced no noticeably better effect on COVID‐19 patients relative to the single‐agent treatment. Additionally, methylprednisolone was efficient in severe and critically severe cases, and superior efficacy could be realized upon its early, appropriate, and short‐term application.

Abstract
Recently, the existence of the tissue renin-angiotensin system (tRAS) has been described for multiple tissues in humans, suggesting its fundamental role in the progression of inflammation and fibrosis. Evidence arises that tRAS might have an impact on the progression of periodontitis and bone loss. However, neither the role of tRAS nor its impact as a therapeutic target have been systematically evaluated for periodontal tissue. The present study sought to characterise tRAS in the periodontal tissue and the effect of its inhibition on periodontal inflammation and bone loss. This systematic review was performed according to the preferred reporting items for systematic reviews and meta analyses (PRISMA) statement. Literature was searched using Web of Science core collection (Web of Science), Medline (Ovid), Cochrane central register of controlled trials (Ovid), Cochrane database of systematic reviews (Ovid), Google Scholar databases and the references of the retrieved studies in March 2020. Information on study design, sample size, population, procedure, type of intervention, observation time, as well as information on sources of bias, was extracted and evaluated. From 455 identified articles, 17 were included in the qualitative synthesis and 11 were included in the quantitative synthesis. Outcomes of studies indicated that the inhibition of tRAS components led to a reduction of periodontal bone loss and inflammation, dependent on the inhibitor used. The findings suggested an important role of tRAS in the periodontal tissue and indicate a potential therapeutic approach for periodontal diseases.

Abstract
Symptomatic intervertebral disc (IVD) degeneration accounts for significant socioeconomic burden. Recently, the expression of the tissue renin-angiotensin system (tRAS) in rat and bovine IVD was demonstrated. The major effector of tRAS is angiotensin II (AngII), which participates in proinflammatory pathways. The present study investigated the expression of tRAS in human IVDs, and the correlation between tRAS, inflammation and IVD degeneration. Human IVD tissue was collected during spine surgery and distributed according to principal diagnosis. Gene expression of tRAS components, proinflammatory and catabolic markers in the IVD tissue was assessed. Hydroxyproline (OHP) and glycosaminoglycan (GAG) content in the IVD tissue were determined. Tissue distribution of tRAS components was investigated by immunohistochemistry. Gene expression of tRAS components such as angiotensin-converting enzyme (ACE), Ang II receptor type 2 (AGTR2), angiotensinogen (AGT) and cathepsin D (CTSD) was confirmed in human IVDs. IVD samples that expressed tRAS components (n = 21) revealed significantly higher expression levels of interleukin 6 (IL-6), tumour necrosis factor α (TNF-α), a disintegrin and metalloproteinase with thrombospondin motifs (ADAMTS) 4 and 5 compared to tRAS-negative samples (n = 37). Within tRAS-positive samples, AGT, matrix-metalloproteinases 13 and 3, IL-1, IL-6 and IL-8 were more highly expressed in traumatic compared to degenerated IVDs. Total GAG/DNA content of non-tRAS expressing IVD tissue was significantly higher compared to tRAS positive tissue. Immunohistochemistry confirmed the presence of AngII in the human IVD. The present study identified the existence of tRAS in the human IVD and suggested a correlation between tRAS expression, inflammation and ultimately IVD degeneration.

Abstract
Introduction Lung transplantation has been performed in a small number of patients suffering from COVID-19 related pulmonary fibrosis or end-stage COVID-19 pneumonia. (1) There are no reports of lung transplantations to receipients with positive Covid-19-PCR at the time of the operation. Methods A 42-year-old woman without comorbidities was hospitalized and diagnosed with COVID-19 pneumonia. After being intubated and tracheotomized, VV-ecmo support had to be initiated, no tendency of improvement ensued. Lung transplantation proceedings were made despite viral RNA test results from BAL being consistently positive (while negative culture growth suggested no active viral disease) since a small intracerebral bleeding had occurred after 45 days on ECMO. An adequate donor organ was found, double lung transplantation was performed. Two experienced anesthetists, two nurse anesthetists and a runner provided anesthesia. The OR was set to positive pressure and 26 air changes h-1, the team wore full PPE (multilayer gloves, gown/overall, FFP-3 masks, glasses, faceshield). Videolaryngoscopic intubation using a ViVaSight® (Ambu, Denmark) left double lumen tube with integrated camera was performed, TEE and bronchoscopy were avoided. We used near infrared spectropscopy and total intravenous anesthesia with Propofol 5,5mg kg-1 h-1 and Sufentanil 5mcg kg-1 h-1. Being on VV-Ecmo with 4,7l of blood and 5,5l O2 flow min-1 we used a second, centrally cannulated parallel ecmo circuit with 3l of blood and 2l of oxygen flow min-1, the VV circuit was reduced. The operation was prolonged due to adhesions, coagulopathy, rupture of the dilated right atrium. Transfusion of 30 units of packed red cells, 40 units of fresh frozen plasma, 5 units of platelets, 2000IE of PPSB, 30mcg of desmopressin acetate, 5 grams of fibrinogen concentrate guided by repetitive viscoelastic testing was performed. Bilateral pulmonary edema occurred, leading to an oxygenation index of 72 on 1l min-1 VV ecmo flow. We therefore switched to a femorally cannulated VA-ecmo circuit to minimize hemodynamic stress for the newly transplanted lungs. At the end of the operation the patient was stable with oxygenation index of 76 with 2,8l min-1 blood flow of ECMO support, sedated with Propofol 5,5mg kg-1 h-1 and Sufentanil 5mcg kg-1 h-1 and received Norepinephrine 0,06 mcg kg-1 min-1. We proned the patient immediately. COVID-19 polymerase chain reaction testing was performed in all team members and was negative in all cases. Results Discussion: Double lung transplantation is possible in selective patients suffering from COVID-19 pneumonia, intraoperative care is troublesome and strains resources due to open lung surgery and airway maneuvers increasing infection risk exponentially.

Abstract
The real-time reverse transcription-polymerase chain reaction (RT-PCR) detection of viral RNA from sputum or nasopharyngeal swab had a relatively low positive rate in the early stage of coronavirus disease 2019 (COVID-19). Meanwhile, the manifestations of COVID-19 as seen through computed tomography (CT) imaging show individual characteristics that differ from those of other types of viral pneumonia such as influenza-A viral pneumonia (IAVP). This study aimed to establish an early screening model to distinguish COVID-19 from IAVP and healthy cases through pulmonary CT images using deep learning techniques. A total of 618 CT samples were collected: 219 samples from 110 patients with COVID-19 (mean age 50 years; 63 (57.3%) male patients); 224 samples from 224 patients with IAVP (mean age 61 years; 156 (69.6%) male patients); and 175 samples from 175 healthy cases (mean age 39 years; 97 (55.4%) male patients). All CT samples were contributed from three COVID-19-designated hospitals in Zhejiang Province, China. First, the candidate infection regions were segmented out from the pulmonary CT image set using a 3D deep learning model. These separated images were then categorized into the COVID-19, IAVP, and irrelevant to infection (ITI) groups, together with the corresponding confidence scores, using a location-attention classification model. Finally, the infection type and overall confidence score for each CT case were calculated using the Noisy-OR Bayesian function. The experimental result of the benchmark dataset showed that the overall accuracy rate was 86.7% in terms of all the CT cases taken together. The deep learning models established in this study were effective for the early screening of COVID-19 patients and were demonstrated to be a promising supplementary diagnostic method for frontline clinical doctors.

Abstract
Abstract
Background
Developments in the working world (e.g. digitalization) are imposing new demands on employees. However, it remains unclear how digitalization affects health and well-being at work and how companies can respond to emerging challenges and opportunities. In order to stimulate the discussion of these issues, the Austrian Health Promotion Fund supported 20 projects focusing on ‘Workplace Health Promotion (WHP) in the Working world 4.0'. The central research questions were: What challenges and opportunities regarding “Work 4.0” were identified and what measures have the companies developed?
Methods
We used a combination of different qualitative and quantitative research methods and instruments. As a first step in this multi-stage process, we conducted workshops with the WHP project managers of each company. Subsequently, we carried out a document analysis of the developed catalogues of measures to identify the underlying opportunities and challenges. To quantify and validate these results, we invited the project leaders and team members to participate in an online survey.
Results
As the WHP projects in the companies progressed, the focus shifted from the challenges to the opportunities offered by digitalization. On average, opportunities were rated more important than challenges in the online survey. The most important challenges were sensitization of managers, permanent accessibility as a health risk and mental stress and strain. The most important opportunities were the optimization of knowledge transfer, communication and documentation. The measures implemented ranged from the use of innovative tools, to knowledge transfer on methods and health-related content, to changes in materials and organization.
Conclusions
The examination of digitalization in the context of health and well-being at work has highlighted the positive aspects of digitalization. The health promotion measures implemented can serve as examples of good practice for other companies.
Key messages
As companies began to consciously examine digitalization in the context of health and well-being at work, the focus shifted from the challenges of digitalization to the opportunities it offers. To meet the challenges of digitalization and to act on emerging opportunities, companies have implemented numerous different measures that can serve as examples of good practice for other companies.

Abstract
Abstract
Background
High quality health promotion (HP) depends on a competent workforce for which professional development programmes for practitioners are essential. The “CompHP Core Competencies Framework in HP” defines crucial competency domains but a recent review concluded that the implementation and use of the framework is lacking. The aim was to develop and validate a self-assessment tool for HP competencies, which should help evaluate training courses.
Methods
A brief self-assessment tool was employed in 2018 in Austria. 584 participants of 77 training courses submitted their post-course assessment (paper-pencil, RR = 78.1%). In addition, longitudinal data are available for 148 participants who filled in a pre-course online questionnaire. Measurement reliability and validity was tested by single factor, bifactor, multigroup, and multilevel CFA. A SEM proved for predictive and concurrent validity, controlling gender and age.
Results
A bifactor model (X2/df=3.69, RMSEA=.07, CFI=.95, sRMR=.07) showed superior results with a strong general CompHP factor (FL>.65, wH=.90, ECV=.85), configurally invariant for two training programmes. On course level, there was only minimal variance between trainings (ICC<.08). Structurally, there was a significant increase in HP competencies when comparing pre- and post-course measurements (b=.33, p<.01). Participants showed different levels of competencies due to prior knowledge (b=.38, p<.001) and course format (b=.16, p<.06). The total scale had good properties (m = 49.8, sd = 10.3, 95%-CI: 49.0-50.7) and discriminated between groups (eg by training length).
Conclusions
The results justify the creation of an overall scale to assess core HP competencies. It is recommended to use the scale for evaluating training courses. The work compensates for the lack of empirical studies on the CompHP concept and facilitates a broader empirical application of a uniform competency framework for HP in accordance with international standards in HP and public health.
Key messages
The self-assessment tool provides a good and compact foundation for assessing HP competencies. It provides a basis for holistic, high quality and sustainable capacity building or development in HP.

Abstract
Background An outbreak of coronavirus disease 2019 (COVID-19) is becoming a public health emergency. Data are limited on the duration and host factors related to viral shedding. Methods In this retrospective study, risk factors associated with severe acute respiratory coronavirus 2 (SARS-CoV-2) RNA shedding were evaluated in a cohort of 113 symptomatic patients from two hospitals outside Wuhan. Results The median duration of SARS-CoV-2 RNA detection was 17 days (Interquartile Range [IQR], 13–22 days) as measured from illness onset. When comparing patients with early (<15 days) and late viral RNA clearance (≥15 days after illness onset), prolonged SARS-CoV-2 RNA shedding was associated with male sex (p=0.009), old age (p=0.033), concomitated with hypertension (p=0.009), delayed admission to hospital after illness onset (p=0.001), severe illness at admission (p=0.049), invasive mechanical ventilation (p=0.006), and corticosteroid treatment (p=0.025). Patients with longer SARS-CoV-2 RNA shedding duration had slower recovery of body temperature (p<0.001) and focal absorption on radiograph images (p<0.001) than patients with early SARS-CoV-2 RNA clearance. Male sex (odds ratio [OR], 3.24 [95% CI, 1.31–8.02]), delayed hospital admission (OR, 1.30 [95% CI, 1.10–1.54]), and invasive mechanical ventilation (OR, 9.88 [95% CI, 1.11–88.02]) were independent risk factors for prolonged SARS-CoV-2 RNA shedding. Conclusions Male sex, delayed admission to hospital after illness onset, and invasive mechanical ventilation were associated with prolonged SARS-CoV-2 RNA shedding. Hospital admission and general treatments should be started as soon as possible in symptomatic COVID-19 patients, especially male patients.

Abstract
Background Coronavirus disease 2019 (COVID-19) was a new emerging disease with high infectiousness. Its diagnosis primarily depended on real-time polymerase chain reaction (RT-PCR) results. This study investigated epidemiological, clinical, and radiological characteristics of COVID-19 with negative RT-PCR results before confirmation. Methods Patients with COVID-19 were enrolled and divided into 2 groups: a negative group with negative RT-PCR results before confirmation and a positive group with positive results at the first detection. Epidemiological and clinical features were compared. Dynamic chest computerized tomography (CT) images of the negative group were evaluated. Results Ninety-nine laboratory-confirmed patients with COVID-19 including 8 patients (8%) with negative RT-PCR results were included. Patients from the negative group had similar epidemiological features: the average age (50.25 ± 13.27 years in the negative group and 53.70 ± 16.64 years in the positive group) and gender distribution (males made up 50% of the negative group and 62.6% of the positive group) were comparable. No significant differences were observed in clinical symptoms between the 2 groups. We found that fever was the most common symptom for both groups, followed by cough, expectoration, chest distress, fatigue, and gastroenterological symptoms. Moreover, ground-glass opacities and consolidations were the main manifestation in chest CT of patients with COVID-19 with or without confirmed RT-PCR results. Conclusions Regardless of initial RT-PCR results, patients with COVID-19 had similar epidemiological, clinical, and chest CT features. Our study suggests value from early chest CT scans in COVID-19 screening and dynamic significance of radiology in disease monitoring should guide clinical decisions.

Abstract
When characterizing the viscoelastic properties of polymers, shear rheological measurements are commonly the method of choice. These properties are known to affect extrusion and nozzle-based processes such as fiber melt spinning, cast film extrusion and 3D-printing. However, an adequate characterization of shear thinning polymers can be challenging and still insufficient to not only describe but predict process relevant influences. Furthermore, the evaluation of rheological model systems in literature is mostly based on stress–relaxation experiments, which are rarely available for various polymeric materials. Therefore, a simple approach is presented, that can be used to evaluate and benchmark a wide range of rheological model systems based on commonly accessible frequency sweep data. The approach is validated by analyzing alginate PH176 solutions of various concentrations, a thermoplastic poly-urethane (TPU) Elastollan 1180A melt, the liquid silicon rubber Elastosil 7670 and a polycaprolactone (PCL) fiber-alginate composite system. The used rheological model systems, consisting of simple springs and dashpots, are suitable for the description of complex, viscoelastic material properties that can be observed for polymer solutions and gel-like systems. After revealing a suitable model system for describing those material properties, the determination and evaluation of relevant model parameters can take place. We present a detailed guideline for the systematic parameter revelation using alginate solutions of different concentrations as example. Furthermore, a starting point for future correlations of strut spreading in 3D-bioprinting and model parameters is revealed. This work establishes the basis for a better understanding and potential predictability of key parameters for various fabrication techniques.

Abstract
Lung transplant is an effective way to treat many end-stage lung diseases. However, one of the main barriers of allograft organ transplant is still the immunologic rejection of transplanted tissue, which is a response of the HLA molecules. Rejection is a complex process involving both T-cell-mediated delayed-type hypersensitivity reactions and antibody-mediated hypersensitivity reactions to histocompatibility molecules on foreign grafts. We report the case of a 25-year-old female patient with cystic fibrosis who underwent 2 lung transplants because of her initial diagnosis and appearance of bronchiolitis obliterans syndrome after the first transplant. Only 13 months after the second transplant, despite the therapies applied, a new rejection occurred associated with high mean fluorescent intensity donor-specific antibody levels, which resulted later in the death of the patient. The present case draws attention to the importance of matching HLA molecules between donor and recipient in addition to immunosuppressive therapy.

Abstract
BACKGROUND Nicotiana rustica (Aztec tobacco), like common tobacco (Nicotiana tabacum), is an allotetraploid formed through a recent hybridization event; however, it originated from completely different progenitor species. Here, we report the comparative genome analysis of wild type N. rustica (5 Gb; 2n = 4x = 48) with its three putative diploid progenitors (2.3-3 Gb; 2n = 2x =24), Nicotiana undulata, Nicotiana paniculata and Nicotiana knightiana. RESULTS In total, 41% of N. rustica genome originated from the paternal donor (N. undulata), while 59% originated from the maternal donor (N. paniculata/N. knightiana). Chloroplast genome and gene analyses indicated that N. knightiana is more closely related to N. rustica than N. paniculata. Gene clustering revealed 14,623 ortholog groups common to other Nicotiana species and 207 unique to N. rustica. Genome sequence analysis indicated that N. knightiana is more closely related to N. rustica than N. paniculata, and that the higher nicotine content of N. rustica leaves is the result of the progenitor genomes combination and of a more active transport of nicotine to the shoot. CONCLUSIONS The availability of four new Nicotiana genome sequences provide insights into how speciation impacts plant metabolism, and in particular alkaloid transport and accumulation, and will contribute to better understanding the evolution of Nicotiana species.

Abstract
SummaryMental health is crucial for public health and prosperity. Yet, mental health was first brought to the EU agenda only in late 1990s. To put mental health firmly on the political agenda, the focus was placed on the positive mental health at a population level. The European Pact for Mental Health and Wellbeing is the most recent mental health policy initiative of the European Commission. It aims at promotion of mental health and prevention of mental disorders, by putting emphasis on five priority areas: prevention of depression and suicide; youth and education; workplace settings; older people; and combating stigma and social exclusion. The Pact calls for co-operation between the EU Member States and the Commission, to identify best practices to tackle the problems in the priority areas and to develop recommendations and action plans. The Pact is currently being implemented by a series of conferences on the priority areas. The European Parliament called for a European Strategy on Mental Health in 2009, but it is unclear whether there is sufficient support for a strategy level document in the Member States and Commission. The implementation process is however expected to culminate in an overall reference framework for promoting mental capital during the Hungarian EU Presidency in 2011. Irrespective of the final outcome, the ongoing process has already increased awareness in Europe of the need for actions to promote mental health.

Abstract
BACKGROUND To determine the safety and immunogenicity of a novel recombinant adenovirus type 5 vector based Ebola virus disease vaccine (Ad5-EBOV) in Africans in China. METHODS A phase 1, dose-escalation, open-label trial was conducted. 61 healthy Africans were sequentially enrolled, with 31 participants receiving one shot intramuscular injection and 30 participants receiving a double-shot regimen. Primary and secondary end points related to safety and immunogenicity were assessed within 28 d after vaccination. This study was registered with ClinicalTrials.gov (NCT02401373). RESULTS Ad5-EBOV is well tolerated and no adverse reaction of grade 3 or above was observed. 53 (86.89%) participants reported at least one adverse reaction within 28 d of vaccination. The most common reaction was fever and the mild pain at injection site, and there were no significant difference between these 2 groups. Ebola glycoprotein-specific antibodies appeared in all 61 participants and antibodies titers peaked after 28 d of vaccination. The geometric mean titres (GMTs) were similar between these 2 groups (1919.01 vs 1684.70 P = 0.5562). The glycoprotein-specific T-cell responses rapidly peaked after 14 d of vaccination and then decreased, however, the percentage of subjects with responses were much higher in the high-dose group (60.00% vs 9.68%, P = 0.0014). Pre-existing Ad5 neutralizing antibodies could significantly dampen the specific humoral immune response and cellular response to the vaccine. CONCLUSION The application of Ad5-EBOV demonstrated safe in Africans in China and a specific GP antibody and T-cell response could occur 14 d after the first immunization. This acceptable safety profile provides a reliable basis to proceed with trials in Africa.
