3Gut bless you:The microbiota-gut-brain axis in irritable bowel syndrome显示文摘Irritable bowel syndrome(IBS)is a common clinical label for medically unexplained gastrointestinal symptoms,recently described as a disturbance of the microbiota-gut-brain axis.Despite decades of research,the pathophysiology of this highly heterogeneous disorder remains elusive.However,a dramatic change in the understanding of the underlying pathophysiological mechanisms surfaced when the importance of gut microbiota protruded the scientific picture.Are we getting any closer to understanding IBS’etiology,or are we drowning in unspecific,conflicting data because we possess limited tools to unravel the cluster of secrets our gut microbiota is concealing?In this comprehensive review we are discussing some of the major important features of IBS and their interaction with gut microbiota,clinical microbiota-altering treatment such as the low FODMAP diet and fecal microbiota transplantation,neuroimaging and methods in microbiota analyses,and current and future challenges with big data analysis in IBS.Eline Margrete Randulff Hillestad Aina van der Meeren Bharat Halandur Nagaraja Ben RenéBjørsvik Noman Haleem Alfonso Benitez-Paez Yolanda Sanz Trygve Hausken Gülen Arslan Lied Arvid Lundervold Birgitte Berentsen 2022World Journal of Gastroenterology2022,28,4:15
4Modelling Hydrological Consequences of Climate Change—Progress and Challenges显示文摘The simulation of hydrological consequences of climate change has received increasing attention fromthe hydrology and land-surface modelling communities. There have been many studies of climate-changeeffects on hydrology and water resources which usually consist of three steps: (1) use of general circulationmodels (GCMs) to provide future global climate scenarios under the effect of increasing greenhouse gases,(2) use of downscaling techniques (both nested regional climate models, RCMs, and statistical methods)for 'downscaling' the GCM output to the scales compatible with hydrological models, and (3) use ofhydrologic models to simulate the effects of climate change on hydrological regimes at various scales.Great progress has been achieved in all three steps during the past few years, however, large uncertaintiesstill exist in every stage of such study. This paper first reviews the present achievements in this field andthen discusses the challenges for future studies of the hydrological impacts of climate change.Chong-yu XU Elin WIDEN Sven HALLDIN 2005Advances in Atmospheric Sciences2005,22,6:14
5Acute compartment syndrome of the thigh following hip replacement by anterior approach in a patient using oral anticoagulants显示文摘Acute compartment syndrome(ACS) of the thigh following primary total hip arthroplasty(THA) is a highly uncommon complication and has not yet been reported before with regards to the anterior approach through the anterior supine interval. We present a case of a 69-year-old male patient with a history of stroke, who developed ACS of the thigh after elective THA while using therapeutic low molecular weight heparin as bridging for regular oral anticoagulation. ACS pathogenesis, diagnostic tools, treatment and relevant literature are discussed. The patient's ACS was recognized in time and treated by operative decompression with fasciotomy of the anterior compartment. Follow-up did not show any neurological deficit or soft-tissue damage.Dirk Pieter Hogerzeil Imraan Muradin Eline W Zwitser Joris A Jansen 2017World Journal of Orthopedics2017,8,12:8
6Six-year outcomes in neovascular age-related macular degeneration with ranibizumab显示文摘● AIM: To evaluate the outcomes of ≥6y ranibizumab therapy in neovascular age-related macular degeneration(AMD).● METHODS: HELIX was a retrospective, observational effeciveness study using medical records of patients treated in three clinics in Belgium. Patients had neovascular AMD and were initially treated with intravitreal ranibizumab(0.5 mg) between November 1, 2007 and October 31, 2008, had ≥6y of data available, and were treated on an ongoing, as-needed basis. Outcomes included best-corrected visual acuity(BCVA) and central retinal thickness(CRT).● RESULTS: The sample consisted of 88 eyes from 69 patients. Mean age was 76.4±6.5y, most patients were female(62.3%). Most eyes(62.5%) were treatment-naive, 33 previously treated eyes had received predominantly other anti-vascular endothelial growth factor agents and verteporfin. Mean baseline BCVA was 57.4±12.7 ETDRS letters and CRT was 292±86 μm. On average, patients received 20.6±11.9 ranibizumab injections over the ≥6y. Intervals between injections were on average 12.7±16.1wk. Mean change in BCVA from baseline to last observation for the sample was less than one letter(-0.9±17.3 letters), with an average loss of-3.2±15.6 letters in previously treated eyes versus a gain of 0.6±18.4 letters in treatment-na?ve eyes. When considering a loss of <15 letters over 6y as stabilization of disease, 75.9% of all eyes showed a positive(improvement or stabilization) outcome. Mean change in CRT from baseline to last observation for the sample was-26.9±148.4 μm with the greatest reduction observed in treatment-naive eyes.● CONCLUSION: This retrospective study of 69 neovascular AMD patients treated for ≥6y with ranibizumab demonstrates long-term visual stabilization. In light of the natural evolution of the disease, these data confirm that ranibizumab is effective long-term under real-world conditions of heterogeneity of patients, clinicians, and centers.Julie Jacob Heidi Brié Anita Leys Laurent Levecq Filip Mevgaerts Kris Denhaerynck Stefaan Vancayzeele Eline Van Craeyveld Ivo Abraham Karen MacDonald 2017International Journal of Ophthalmology(English edition)2017,10,1:5
7Adult female syphilis prevalence,congenital syphilis case incidence and adverse birth outcomes,Mongolia 2000e2016:Estimates using the Spectrum STI tool显示文摘Introduction:Mongolia's health ministry prioritizes control of Sexually Transmitted Infections,including syphilis screening and treatment in antenatal care(ANC).Methods:Adult syphilis prevalence trends were fitted using the Spectrum-STI estimation tool,using data from ANC surveys and routine screening over 1997e2016.Estimates were combined with programmatic data to estimate numbers of treated and untreated pregnant women with syphilis and associated incidence congenital syphilis(CS)and CS-attributable adverse birth outcomes(ABO),which we compared with CS case reports.Results:Syphilis prevalence in pregnant women was estimated at 1.7%in 2000 and 3.0%in 2016.We estimated 652 CS cases,of which 410 ABO,in 2016.Far larger,annually increasing numbers of CS cases and ABO were estimated to have been prevented:1654 cases,of which 789 ABO in 2016thanks to increasing coverages of ANC(99%in 2016),ANC-based screening(97%in 2016)and treatment of women diagnosed(81%in 2016).The 42 CS cases reported nationally over 2016(liveborn infants only)represented 27%of liveborn infants with clinical CS,but only 7%of estimated CS cases among women found syphilis-infected in ANC,and 6%of all estimated CS cases including those born to women with undiagnosed syphilis.Discussion/Conclusion:Mongolia's ANC-based syphilis screening program is reducing CS,but maternal prevalence remains high.To eliminate CS(target:<50 cases per 100,000 live births),Mongolia should strengthen ANC services,limiting losses during referral for treatment,and under-diagnosis of CS including still-births and neonatal deaths,and expand syphilis screening and prevention programs.Erdenetungalag Enkhbat Eline L.Korenromp Jugderjav Badrakh Setsen Zayasaikhan Purevsuren Baya Enkhjargal Orgiokhuu Narantuya Jadambaa Sergelen Munkhbaatar Delgermaa Khishigjargal Narantuya Khad Guy Mahiane Naoko Ishikawa Davaalkham Jagdagsuren Melanie M.Taylor 2018Infectious Disease Modelling2018,3,1:4

9Bone remodeling effect of a chitosan and calcium phosphate-based composite显示文摘Chitosan is a biocompatible polymer that has been widely studied for tissue engineering purposes.The aim of this research was to assess bone regenerative properties of an injectable chitosan and calcium phosphate-based composite and identify optimal degree of deacetylation(%DDA)of the chitosan polymer.Drill holes were generated on the left side of a mandible in Sprague-Dawley rats,and the hole was either left empty or filled with the implant.The animals were sacrificed at several time points after surgery(7–22 days)and bone was investigated using micro-CT and histology.No significant new bone formation was observed in the implants themselves at any time points.However,substantial new bone formation was observed in the rat mandible further away from the drill hole.Morphological changes indicating bone formation were found in specimens explanted on Day 7 in animals that received implant.Similar bone formation pattern was seen in control animals with an empty drill hole at later time points but not to the same extent.A second experiment was performed to examine if the%DDA of the chitosan polymer influenced the bone remodeling response.The results suggest that chitosan polymers with%DDA between 50 and 70%enhance the natural bone remodeling mechanism.Lilja Kjalarsdottir Arna Dyrfjord Atli Dagbjartsson Elin H.Laxdal Gissur Orlygsson Johannes Gislason Jon M.Einarsson Chuen-How Ng Halldor Jonsson Jr 2019Regenerative Biomaterials2019,6,4:3
10Positron emission tomography to assess hypoxia and perfusion in lung cancer显示文摘In lung cancer, tumor hypoxia is a characteristic feature, which is associated with a poor prognosis and resistance to both radiation therapy and chemotherapy. As the development of tumor hypoxia is associated with decreased perfusion, perfusion measurements provide more insight into the relation between hypoxia and perfusion in malignant tumors. Positron emission tomography(PET) is a highly sensitive nuclear imaging technique that is suited for non-invasive in vivo monitoring of dynamic processes including hypoxia and its associated parameter perfusion. The PET technique enables quantitative assessment of hypoxia and perfusion in tumors. To this end, consecutive PET scans can be performed in one scan session. Using different hypoxia tracers, PET imaging may provide insight into the prognostic significance of hypoxia and perfusion in lung cancer. In addition, PET studies may play an important role in various stages of personalized medicine, as these may help to select patients for specifictreatments including radiation therapy, hypoxia modifying therapies, and antiangiogenic strategies. In addition, specific PET tracers can be applied for monitoring therapy. The present review provides an overview of the clinical applications of PET to measure hypoxia and perfusion in lung cancer. Available PET tracers and their characteristics as well as the applications of combined hypoxia and perfusion PET imaging are discussed.Eline E Verwer Ronald Boellaard Astrid AM van der Veldt 2014World Journal of Clinical Oncology2014,5,5:3
