| 1 | Prevention of stress-related ulcer bleeding at the intensive care unit: Risks and benefits of stress ulcer prophylaxis显示文摘Stress-related mucosal disease is a typical complication of critically ill patients in the intensive care unit(ICU). It poses a risk of clinically relevant upper gastrointestinal(GI) bleeding. Therefore, stress ulcer prophylaxis(SUP)is recommended in high-risk patients, especially those mechanically ventilated > 48 h and those with a manifest coagulopathy. Proton pump inhibitors(PPI) and, less effectively, histamine 2 receptor antagonists(H2RA) prevent GI bleeding in critically ill patients in the ICU. However, the routine use of pharmacological SUP does not reduce overall mortality in ICU patients. Moreover, recent studies revealed that SUP in the ICU might be associated with potential harm such as an increased risk of infectious complications, especially nosocomial pneumonia and Clostridium difficile-associated diarrhea. Additionally, special populations such as patients with liver cirrhosis may even have an increased mortality rate if treated with PPI. Likewise, PPI can be toxic for both the liver and the bone marrow, and some PPI show clinically relevant interactions with important other drugs like clopidogrel. Therefore, the agent of choice, the specific balance of risks and benefits for individual patients as well as the possible dose of PPI has to be chosen carefully. Alternatives to PPI prophylaxis include H2 RA and/or sucralfate. Instead of routine SUP, further trials should investigate risk-adjusted algorithms, balancing benefits and threats of SUP medication in the ICU. | Lukas Buendgens Alexander Koch Frank Tacke | 2016 | World Journal of Critical Care Medicine2016，5，1： | 24 |
| 2 | Distinct gut microbiota profiles in patients with primary sclerosing cholangitis and ulcerative colitis显示文摘AIM To characterize the gut bacterial microbiota of patients with primary sclerosing cholangitis(PSC) and ulcerative colitis(UC).METHODS Stool samples were collected and relevant clinical data obtained from 106 study participants, 43 PSC patients with(n = 32) or without(n = 11) concomitant inflammatory bowel disease, 32 UC patients, and 31 healthy controls. The V3 and V4 regions of the 16 S ribosomal RNA gene were sequenced on Illumina Mi Seq platform to cover low taxonomic levels. Data were further processed in QIIME employing Ma As Lin and LEf Se tools for analysis of the output data.RESULTS Microbial profiles in both PSC and UC were characterized by low bacterial diversity and significant change in global microbial composition. Rothia, Enterococcus, Streptococcus, Veillonella, and three other genera were markedly overrepresented in PSC regardless of concomitant inflammatory bowel disease(IBD). Rothia, Veillonella and Streptococcus were tracked to the species level to identify Rothia mucilaginosa, Streptococcus infantus, S. alactolyticus, and S. equi along with Veillonella parvula and V. dispar. PSC was further characterized by decreased abundance of Adlercreutzia equolifaciens and Prevotella copri. Decrease in genus Phascolarctobacterium was linked to presence of colonic inflammation regardless of IBD phenotype. Akkermansia muciniphila, Butyricicoccus pullicaecorum and Clostridium colinum were decreased in UC along with genus Roseburia. Low levels of serum albumin were significantly correlated with enrichment of order Actinomycetales.CONCLUSION PSC is associated with specific gut microbes independently of concomitant IBD and several bacterial taxa clearly distinguish IBD phenotypes(PSC-IBD and UC). | Lukas Bajer Miloslav Kverka Martin Kostovcik Peter Macinga Jiri Dvorak Zuzana Stehlikova Jan Brezina Pavel Wohl Julius Spicak Pavel Drastich | 2017 | World Journal of Gastroenterology2017，23，25： | 22 |

| 5 | Clinical algorithms for the prevention of variceal bleeding and rebleeding in patients with liver cirrhosis显示文摘Portal hypertension(PH),a common complication of liver cirrhosis,results in development of esophageal varices.When esophageal varices rupture,they cause significant upper gastrointestinal bleeding with mortality rates up to 20%despite state-of-the-art treatment.Thus,prophylactic measures are of utmost importance to improve outcomes of patients with PH.Several high-quality studies have demonstrated that non-selective beta blockers(NSBBs)or endoscopic band ligation(EBL)are effective for primary prophylaxis of variceal bleeding.In secondary prophylaxis,a combination of NSBB+EBL should be routinely used.Once esophageal varices develop and variceal bleeding occurs,standardized treatment algorithms should be followed to minimize bleeding-associated mortality.Special attention should be paid to avoidance of overtransfusion,early initiation of vasoconstrictive therapy,prophylactic antibiotics and early endoscopic therapy.Pre-emptive transjugular intrahepatic portosystemic shunt should be used in all Child C10-C13 patients experiencing variceal bleeding,and potentially in Child B patients with active bleeding at endoscopy.The use of carvedilol,safety of NSBBs in advanced cirrhosis(i.e.with refractory ascites)and assessment of hepatic venous pressure gradient response to NSBB is discussed.In the present review,we give an overview on the rationale behind the latest guidelines and summarize key papers that have led to significant advances in the field. | Nikolaus Pfisterer Lukas W Unger Thomas Reiberger | 2021 | World Journal of Hepatology2021，13，7： | 11 |
| 6 | An acorn squash (Cucurbita pepo ssp. ovifera) fruit and seed transcriptome as a resource for the study of fruit traits in Cucurbita显示文摘Acorn squash(Cucurbita pepo)is an iconic fall vegetable in the United States,known for its unique fruit shape and also prized for its culinary properties.Little is known about the metabolism that underlies the development of fruit quality attributes such as color,sweetness,texture and nutritional qualities in acorn squash,or any other winter squash grown worldwide.To provide insight into winter squash fruit and seed development and add to the genomic resources in the Cucurbita genus,RNA sequencing was used to generate an acorn squash fruit and seed transcriptome from the cultivar Sweet REBA at critical points throughout fruit development.141838600 high-quality paired-end Illumina reads were assembled into 55949 unigenes.85%of unigenes with predicted open reading frames had homology with previously identified genes and over 62%could be functionally annotated.Comparison with the watermelon and cucumber genomes provided confirmation that the unigenes are full-length and comprehensive,covering an average of 90%of the coding sequence of their homologs and 72%of the cucumber and watermelon exomes.Key candidate genes associated with carotenoid and carbohydrate metabolism were identified toward a resource for winter squash fruit quality trait dissection.This transcriptome represents a major advance in C.pepo genomics,providing significant new sequence information and revealing the repertoire of genes expressed throughout winter squash fruit and seed development.Future studies on the genetic basis of fruit quality and future breeding efforts will be enhanced by tools and insights developed from this resource. | Lindsay E Wyatt Susan R Strickler Lukas A Mueller Michael Mazourek | 2015 | Horticulture Research2015，2，1： | 11 |
| 7 | Photovoltaic yield prediction using an irradiance forecast model based on multiple neural networks显示文摘In order to develop predictive control algorithms for efficient energy management and monitoring for residential grid connected photovoltaic systems, accurate and reliable photovoltaic(PV) power forecasts are required.A PV yield prediction system is presented based on an irradiance forecast model and a PV model. The PV power forecast is obtained from the irradiance forecast using the PV model. The proposed irradiance forecast model is based on multiple feed-forward neural networks. The global horizontal irradiance forecast has a mean absolute percentage error of 3.4% on a sunny day and 23% on a cloudy day for Stuttgart. PV power forecasts based on the neural network irradiance forecast have performed much better than the PV power persistence forecast model. | Saad Parvaiz DURRANI Stefan BALLUFF Lukas WURZER Stefan KRAUTER | 2018 | Journal of Modern Power Systems and Clean Energy2018，6，2： | 10 |
| 8 | 在最后三扫描仪代的 CT 剂量和图象质量显示文摘 AIM: To compare the computed tomography(CT) dose and image quality with the filtered back projection against the iterative reconstruction and CT with a minimal electronic noise detector. METHODS: A lung phantom(Chest Phantom N1 by Kyoto Kagaku) was scanned with 3 different CT scanners: the Somatom Sensation, the Definition Flash and the Definition Edge(all from Siemens, Erlangen, Germany). The scan parameters were identical to the Siemens presetting for THORAX ROUTINE(scan length 35 cm and FOV 33 cm). Nine different exposition levels were examined(reference mAs/peek voltage): 100/120, 100/100, 100/80, 50/120, 50/100, 50/80, 25/120, 25/100 and 25 mAs/80 kVp. Images from the SOMATOM Sensation were reconstructed using classic filtered back projection. Iterative reconstruction(SAFIRE, level 3) was performed for the two other scanners. A Stellar detector was used with the Somatom Definition Edge. The CT doses were represented by the dose length products(DLPs)(mGycm) provided by the scanners. Signal, contrast, noise and subjective image quality were recorded by two different radiologists with 10 and 3 years of experience in chest CT radiology. To determine the average dose reduction between two scanners, the integral of the dose difference was calculated from the lowest to the highest noise level. RESULTS: When using iterative reconstruction(IR) instead of filtered back projection(FBP), the average dose reduction was 30%, 52% and 80% for bone, soft tissue and air, respectively, for the same image quality(P < 0.0001). The recently introduced Stellar detector(Sd) lowered the radiation dose by an additional 27%, 54% and 70% for bone, soft tissue and air, respectively(P < 0.0001). The benefit of dose reduction was larger at lower dose levels. With the same radiation dose, an average of 34%(22%-37%) and 25%(13%-46%) more contrast to noise was achieved by changing from FBP to IR and from IR to Sd, respectively. For the same contrast to noise level, an average of 59%(46%-71%) and 51%(38%-68%) dose reduction was produced for IR and Sd, respectively. For the same subjective image quality, the dose could be reduced by 25%(2%-42%) and 44%(33%-54%) using IR and Sd, respectively. CONCLUSION: This study showed an average dose reduction between 27% and 70% for the new Stellar detector, which is equivalent to using IR instead of FBP. | Andreas Christe Johannes Heverhagen Christoph Ozdoba Christian Weisstanner Stefan Ulzheimer Lukas Ebner | 2013 | World Journal of Radiology2013，5，11： | 10 |
| 9 | Functional brain imaging of gastrointestinal sensation in health and disease显示文摘It has since long been known, from everyday experience as well as from animal and human studies, that psychological processes-both affective and cognitive- exert an influence on gastrointestinal sensorimotor function. More specifi cally, a link between psychological factors and visceral hypersensitivity has been suggested, mainly based on research in functional gastrointestinal disorder patients. However, until recently, the exact nature of this putative relationship remained unclear, mainly due to a lack of non-invasive methods to study the (neurobiological) mechanisms underlying this relationship in non-sleeping humans. As functional brain imaging, introduced in visceral sensory neuroscience some 10 years ago, does provide a method for in vivo study of brain-gut interactions, insight into the neurobiological mechanisms underlying visceral sensation in general and the influence of psychological factors more particularly, has rapidly grown. In this article, an overview of brain imaging evidence on gastrointestinal sensation will be given, with special emphasis on the brain mechanisms underlying the interaction between affective & cognitive processes and visceral sensation. First, the reciprocal neural pathways between the brain and the gut (brain- gut axis) will be briefky outlined, including brain imaging evidence in healthy volunteers. Second, functional brain imaging studies assessing the influence of psychological factors on brain processing of visceral sensation in healthy humans will be discussed in more detail. Finally, brain imaging work investigating differences in brain responses to visceral distension between healthy volunteers and functional gastrointestinal disorderpatients will be highlighted. | Lukas Van Oudenhove Steven J Coen Qasim Aziz | 2007 | World Journal of Gastroenterology2007，13，25： | 9 |

| 11 | Developing More Effective Enhanced Biochar Fertilisers for Improvement of Pepper Yield and Quality显示文摘Utilization of biochar at high application rates can increase soil C and crop yields, decrease greenhouse gas emissions and reduce nutrient run-off from soils. However, the high application rate of 10 t ha-1may not return a profit to the farmer due to the high cost of biochar. In this study biochar was modified through pre-treating the biomass and post-treating with phosphoric acid, minerals and different chemical fertilisers to study the effects of two new enhanced biochar fertilisers on the yield and quality of green pepper in a field experiment with 5 fertilisation treatments and 3 replications. The two new biochar fertilisers significantly(P < 0.05) increased the yield of green pepper(11.33–11.47 t ha-1), compared with the conventional chemical fertiliser(9.72 t ha-1). The biochar fertiliser treatments improved the vitamin C content of green pepper from 236.99 to 278.28 mg kg-1, and also significantly(P < 0.05) reduced the nitrate content from 132.32 to 101.92 mg kg-1, compared with chemical fertiliser. This study indicated that, compared to the use of conventional chemical fertiliser, all of the biochar fertiliser treatments could significantly improve the yield and quality of green pepper. | YAO Chunxue Stephen JOSEPH LI Lianqing PAN Genxing Yun LIN Paul MUNROE Ben PACE Sarasadat TAHERYMOOSAVI Lukas VAN ZWIETEN Torsten THOMAS Shaun NIELSEN Jun YE Scott DONNE | 2015 | Pedosphere2015，25，5： | 8 |
| 12 | Comparison of high-resolution ultrasound and MR-enterography in patients with inflammatory bowel disease显示文摘AIM:To compare the results of high-resolution ultrasound(HR-US) and magnetic resonance enterography(MRE) examinations in patients with inflammatory bowel disease(IBD).METHODS:The reports of 250 consecutive cases with known IBD,who had an MRE and HR-US examination,were retrospectively analyzed.Using a patient-based approach we evaluated morphological disease features such as affected bowel wall,stenosis,abscess and fistula.The comparison between the two modalities was based on the hypothesis,that any pathological change described in any imaging modality was a true finding,as no further standard of reference was available for complete assessment.RESULTS:Two hundred and fifty examinations representing 207 different patients were evaluated.Both modalities assessed similar bowel wall changes in 65% of the examinations,with more US findings in 11% and more MRE findings in 15%.When the reports were analyzed with regard to 'bowel wall inflammation',US reported more findings in 2%,while MRE reported more findings in 53%.Stenoses were assessed to be identical in 8%,while US found more in 3% and MRE in 29%(P < 0.01).For abscess detection,US showed more findings in 2%(n = 4) while MRE detected more in 6%(n = 16).US detected more fistulas in 1%(n = 2),while MRE detected more in 13%(n = 32)(P < 0.001).The most common reason for no detected pathology by US was a difficult to assess anatomical region(lesser pelvis,n = 72).CONCLUSION:US can miss clinically relevant pathological changes in patients with IBD mostly due to difficulty in assessing certain anatomical regions. | Andreas G Schreyer Cynthia Menzel Chris Friedrich Florian Poschenrieder Lukas Egger Christian Dornia Gabriela Schill Lena M Dendl Doris Schacherer Christl Girlich Ernst-Michael Jung | 2011 | World Journal of Gastroenterology2011，17，8： | 7 |
| 13 | Comparative analysis of Cucurbita pepo metabolism throughout fruit development in acorn squash and oilseed pumpkin显示文摘Both the fruit mesocarp and the seeds of winter squash can be used for consumption,although the focus of breeding efforts varies by cultivar.Cultivars bred for fruit consumption are selected for fruit mesocarp quality traits such as carotenoid content,percent dry matter,and percent soluble solids,while these traits are essentially ignored in oilseed pumpkins.To compare fruit development in these two types of squash,we sequenced the fruit transcriptome of two cultivars bred for different purposes:an acorn squash,‘Sweet REBA’,and an oilseed pumpkin,‘Lady Godiva’.Putative metabolic pathways were developed for carotenoid,starch,and sucrose synthesis in winter squash fruit and squash homologs were identified for each of the structural genes in the pathways.Gene expression,especially of known rate-limiting and branch point genes,corresponded with metabolite accumulation both across development and between the two cultivars.Thus,developmental regulation of metabolite genes is an important factor in winter squash fruit quality. | Lindsay E Wyatt Susan R Strickler Lukas A Mueller Michael Mazourek | 2016 | Horticulture Research2016，3，1： | 7 |

| 16 | Expression of the oxygen-sensitive transcription factor subunit HIF-1α in patients suffering from secondary Raynaud syndrome显示文摘Anti-ischemic therapy remains a challenge due to the complexity of hypoxia response pathways. Hypoxia-inducible factor (HIF)-1 is a heterodimer tran scription factor con sisti ng of 2 sub units, HIF-1α and HIF-1β. Hypoxia-depe ndent activatio n of HIF-1α regulates cellular 02 homeostasis. Raynaud syndrome (RS), as a comorbidity of the autoimmune disease systemic sclerosis (SS), is characterized by vasospasms that limit blood flow to the limbs, resulting in hypoxia. A single-center randomized study was con ducted to compare prostagla ndin E1 (PgEI) therapy with a treatme nt combi ning PgE1 and an en dotheli n-1 blocker, bosentan. A total of 30 patients suffering from SS with RS were enrolled. We examined the regulation of HIF-1α, its target heme oxygenase-1 (HMOX-1), and the serum levels of the HIF-1α protein in a subset of patients as well as in ten healthy individuals. The expression of HIF-1α and HMOX-1 in monocytes was measured using absolute plasmid-based quantitative real-time PCR, whereas serum HIF-1α levels were measured with ELISA. Samples were taken at the time of randomization and after 24 weeks. We found that HIF-1α and HMOX-1 mRNA expression in monocytes and serum HIF-1α protein levels were significantly higher in the SS/RS patients compared to the healthy control group. Single-drug therapy significantly increased HIF-1α and HMOX-1 mRNA expression in monocytes and serum HIF-1α protein levels in the SS/RS patients compared to those at the time of randomization, whereas combining PgE1 with an en dotheli n-1 blocker preve nted the further in creases in HIF-1α and HMOX-1 expressi on. We propose HIF-1α and HMOX-1 as novel markers for anti-ischemic therapy in RS. | Lukas Andreas Heger Mark Kerber Marcus Hortmann Samuel Robinson Maximilian Mauler Daniela Stallmann Daniel Duerschmied Christoph Bode Christoph Hehrlein Ingo Ahrens | 2019 | Acta Pharmacologica Sinica2019，40，4： | 5 |

| 18 | Simultaneous occurrence of autoimmune pancreatitis and pancreatic cancer in patients resected for focal pancreatic mass显示文摘AIM To assess the occurrence of autoimmune pancreatitis(AIP) in pancreatic resections performed for focal pancreatic enlargement.METHODS We performed a retrospective analysis of medical records of all patients who underwent pancreatic resection for a focal pancreatic enlargement at our tertiary center from January 2000 to July 2013. The indication for surgery was suspicion of a tumor based on clinical presentation, imaging findings and laboratory evaluations. The diagnosis of AIP was based on histology findings. An experienced pathologist specialized in pancreatic disease reviewed all the cases and confirmed the diagnosis in pancreatic resection specimens suggestive of AIP. The histological diagnosis of AIP was set according to the international consensus diagnostic criteria.RESULTS Two hundred ninety-five pancreatic resections were performed in 201 men and 94 women. AIP was diagnosed in 15 patients(5.1%, 12 men and 3 women) based on histology of the resected specimen. Six of them had AIP type 1, nine were diagnosed with AIP type 2. Pancreatic adenocarcinoma(PC) was also present in six patients with AIP(40%), all six were men. Patients with AIP + PC were significantly older(60.5 vs 49 years of age, P = 0.045), more likely to have been recently diagnosed with diabetes(67% vs 11%, P = 0.09), and had experienced greater weight loss(15.5 kg vs 8.5 kg, P = 0.03) than AIP patients without PC. AIP was not diagnosed in any patients prior to surgery; however, the diagnostic algorithm was not fully completed in every case. CONCLUSION The possible co-occurrence of PC and AIP suggests that preoperative diagnosis of AIP does not rule out simultaneous presence of PC. | Peter Macinga Adela Pulkertova Lukas Bajer Jana Maluskova Martin Oliverius Martin Smejkal Maria Heczkova Julius Spicak Tomas Hucl | 2017 | World Journal of Gastroenterology2017，23，12： | 5 |
| 19 | Sodium-glucose cotransporter 2 inhibitors’ mechanisms of action in heart failure显示文摘Three major cardiovascular outcome trials(CVOTs)with a new class of antidiabetic drugs-sodium-glucose cotransporter 2(SGLT2)inhibitors(EMPAREG OUTCOME trial with empagliflozin,CANVAS Program with canagliflozin,DECLARE-TIMI 58 with dapagliflozin)unexpectedly showed that cardiovascular outcomes could be improved possibly due to a reduction in heart failure risk,which seems to be the most sensitive outcome of SGLT2 inhibition.No other CVOT to date has shown any significant benefit on heart failure events.Even more impressive findings came recently from the DAPA-HF trial in patients with confirmed and well-treated heart failure:Dapagliflozin was shown to reduce heart failure risk for patients with heart failure with reduced ejection fraction regardless of diabetes status.Nevertheless,despite their possible wide clinical implications,there is much doubt about the mechanisms of action and a lot of questions to unravel,especially now when their benefits translated to nondiabetic patients,rising doubts about the validity of some current mechanistic assumptions.The time frame of their cardiovascular benefits excludes glucoselowering and antiatherosclerotic-mediated effects and multiple other mechanisms,direct cardiac as well as systemic,are suggested to explain their early cardiorenal benefits.These are:Anti-inflammatory,antifibrotic,antioxidative,antiapoptotic properties,then renoprotective and hemodynamic effects,attenuation of glucotoxicity,reduction of uric acid levels and epicardial adipose tissue,modification of neurohumoral system and cardiac fuel energetics,sodiumhydrogen exchange inhibition.The most logic explanation seems that SGLT2 inhibitors timely target various mechanisms underpinning heart failure pathogenesis.All the proposed mechanisms of their action could interfere with evolution of heart failure and are discussed separately within the main text. | Petra Grubić Rotkvić Maja Cigrovski Berković Nikola Bulj Luka Rotkvić Ivana Ćelap | 2020 | World Journal of Diabetes2020，11，7： | 5 |
| 20 | Handgrip strength and health outcomes: Umbrella review of systematic reviews with meta-analyses of observational studies显示文摘Purpose:The aim of the present study was to assess both the credibility and strength of evidence arising from systematic reviews with meta-analyses of observational studies on handgrip strength and health outcomes.Methods:An umbrella review of systematic reviews with meta-analyses of observational studies was conducted.We assessed meta-analyses of observational studies based on random-effect summary effect sizes and their p values,95%prediction intervals,heterogeneity,small-study effects,and excess significance.We graded the evidence from convincing(Class I)to weak(Class IV).Results:From 504 articles returned in a search of the literature,8 systematic reviews were included in our review,with a total of 11 outcomes.Overall,nine of the 11 of the outcomes reported nominally significant summary results(p<0.05),with 4 associations surviving the application of the more stringent p value(p<106).No outcome presented convincing evidence.Three associations showed Class II evidence(i.e.,highly suggestive):(1)higher handgrip values at baseline were associated with a minor reduction in mortality risk in the general population(n=34 studies;sample size=1,855,817;relative risk=0.72,95%confidence interval(95%CI):0.670.78),(2)cardiovascular death risk in mixed populations(n=15 studies;relative risk=0.84,95%CI:0.780.91),and(3)incidence of disability(n=7 studies;relative risk=0.76,95%CI:0.660.87).Conclusion:The present results show that handgrip strength is a useful indicator for general health status and specifically for early all-cause and cardiovascular mortality,as well as disability.To further inform intervention strategies,future research is now required to fully understand mechanisms linking handgrip strength scores to these health outcomes. | Pinar Soysal Christopher Hurst Jacopo Demurtas Joseph Firth Reuben Howden Lin Yang Mark A.Tully Ai Koyanagi Petre Cristian Ilie Guillermo F.Lopez-Sanchez Lukas Schwingshackl Nicola Veronese Lee Smith | 2021 | Journal of Sport and Health Science2021，10，3： | 5 |
