1Adhesive small bowel adhesions obstruction: Evolutions in diagnosis, management and prevention显示文摘Intra-abdominal adhesions following abdominal surgery represent a major unsolved problem. They are the first cause of small bowel obstruction. Diagnosis is based on clinical evaluation, water-soluble contrast followthrough and computed tomography scan. For patients presenting no signs of strangulation, peritonitis or severe intestinal impairment there is good evidence to support non-operative management. Open surgery is the preferred method for the surgical treatment of adhesive small bowel obstruction, in case of suspected strangulation or after failed conservative management, but laparoscopy is gaining widespread acceptance especially in selected group of patients. 'Good' surgical technique and anti-adhesive barriers are the main current concepts of adhesion prevention. We discuss current knowledge in modern diagnosis and evolving strategies for management and prevention that are leading to stratified care for patients.Fausto Catena Salomone Di Saverio Federico Coccolini Luca Ansaloni Belinda De Simone Massimo Sartelli Harry Van Goor 2016World Journal of Gastrointestinal Surgery2016,8,3:28
2Inferring the Tree of Life of the order Cypriniformes, the earth's most diverse clade of freshwater fishes: Implications of varied taxon and character sampling显示文摘The phylogenetic relationships of species are fundamental to any biological investigation, including all evolutionary studies. Accurate inferences of sister group relationships provide the researcher with an historical framework within which the attributes or geographic origin of species (or supraspecific groups) evolved. Taken out of this phylogenetic context, interpretations of evolutionary processes or origins, geographic distributions, or speciation rates and mechanisms, are subject to nothing less than a biological experiment without controls. Cypriniformes is the most diverse clade of freshwater fishes with estimates of diversity of nearly 3,500 species. These fishes display an amazing array of morphological, ecological, behavioral, and geographic diversity and offer a tremendous opportunity to enhance our understanding of the biotic and abiotic factors associated with diversification and adaptation to environments. Given the nearly global distribution of these fishes, they serve as an important model group for a plethora of biological investigations, including indicator species for future cli-matic changes. The occurrence of the zebrafish, Danio rerio, in this order makes this clade a critical component in understanding and predicting the relationship between mutagenesis and phenotypic expressions in vertebrates, including humans. With the tremendous diversity in Cypriniformes, our understanding of their phylogenetic relationships has not proceeded at an acceptable rate, despite a plethora of morphological and more recent mo-lecular studies. Most studies are pre-Hennigian in origin or include relatively small numbers of taxa. Given that analyses of small numbers of taxa for molecular characters can be compromised by peculiarities of long-branch attraction and nodal-density effect, it is critical that significant progress in our understanding of the relationships of these important fishes occurs with increasing sampling of species to mitigate these potential problems. The recent Cypriniformes Tree of Life initiative is an effort to achieve this goal with morphological and molecular (mitochondrial and nuclear) data. In this early synthesis of our understanding of the phylogenetic relationships of these fishes, all types of data have contributed historically to improving our understanding, but not all analyses are complementary in taxon sampling, thus precluding direct understanding of the impact of taxon sampling on achieving accurate phylogenetic inferences. However, recent molecular studies do provide some insight and in some instances taxon sampling can be implicated as a variable that can influence sister group relationships. Other instances may also exist but without inclusion of more taxa for both mitochondrial and nuclear genes, one cannot distinguish between inferences being dictated by taxon sampling or the origins of the molecular data.Richard L.

4A history of high-power laser research and development in the United Kingdom显示文摘The first demonstration of laser action in ruby was made in 1960 by T.H.Maiman of Hughes Research Laboratories,USA.Many laboratories worldwide began the search for lasers using different materials,operating at different wavelengths.In the UK,academia,industry and the central laboratories took up the challenge from the earliest days to develop these systems for a broad range of applications.This historical review looks at the contribution the UK has made to the advancement of the technology,the development of systems and components and their exploitation over the last 60 years.Colin N.Danson Malcolm White John R.M.Barr Thomas Bett Peter Blyth David Bowley Ceri Brenner Robert J.Collins Neal Croxford A.E.Bucker Dangor Laurence Devereux Peter E.Dyer Anthony Dymoke-Bradshaw Christopher B.Edwards Paul Ewart Allister I.Ferguson John M.Girkin Denis R.Hall David C.Hanna Wayne Harris David I.Hillier Christopher J.Hooker Simon M.Hooker Nicholas Hopps Janet Hull David Hunt Dino A.Jaroszynski Mark Kempenaars Helmut Kessler Sir Peter L.Knight Steve Knight Adrian Knowles Ciaran L.S.Lewis Ken S.Lipton Abby Littlechild John Littlechild Peter Maggs Graeme P.A.Malcolm OBE Stuart P.D.Mangles William Martin Paul McKenna Richard O.Moore Clive Morrison Zulfikar Najmudin David Neely Geoff H.C.New Michael J.Norman Ted Paine Anthony W.Parker Rory R.Penman Geoff J.Pert Chris Pietraszewski Andrew Randewich Nadeem H.Rizvi Nigel Seddon MBE Zheng-Ming Sheng David Slater Roland A.Smith Christopher Spindloe Roy Taylor Gary Thomas John W.G.Tisch Justin S.Wark Colin Webb S.Mark Wiggins Dave Willford Trevor Winstone 2021High Power Laser Science and Engineering2021,9,2:5
5Recurrent ectopic pancreatitis of the jejunum and mesentery over a 30-year period显示文摘BACKGROUND:Ectopic pancreas is defined as pancreatic tissue found outside its usual anatomical position,with no ductal or vascular communication with the native pancreas. We describe a case of ectopic pancreas of the small bowel and mesentery causing recurrent episodes of pancreatitis, initially suspected on computed tomography(CT)and magnetic resonance cholangiopancreatography(MRCP),and confirmed on histological review of the resection. METHODS:A 67-year-old woman presented with clinical symptoms and biochemical evidence of pancreatitis.She had similar episodes over the past 30 years with unrevealing investigations,and was concluded to have idiopathic pancreatitis. She underwent CT and MRCP,with findings suggestive of ectopic pancreas,a diagnosis confirmed on histology of the resection. RESULTS:MRCP identified a mass in the proximal small bowel mesentery isointense to the native pancreas,with a small duct draining into a proximal jejunal loop.The resected specimen consisted of normal parenchyma with lobulated acinar tissue with scattered islets of Langerhans,an occasional ductular structure,and admixed areas of adipose tissue.The patient remained asymptomatic with normal biochemistry six months post-operatively. CONCLUSION:In an individual with abdominal pain,elevated serum amylase/lipase,but imaging findings of a normal native pancreas,ectopic pancreatitis should be considered,and can be evaluated by CT and MRCP.John CT Wong Charlotte Robinson Edward C Jones Alison Harris Charles Zwirewich Robert Wakefield Richard K Simons Eric M Yoshida 2011Hepatobiliary & Pancreatic Diseases International2011,10,2:4
6Jejunal diverticulosis is not always a silent spectator:A report of 4 cases and review of the literature显示文摘Jejunal diverticulosis (JD) is a rare clinical entity. The potential complications of this condition are discussed here through a series of cases presented to our centre. A retrospective analysis of four cases, which were diagnosed and treated, was performed. These included two cases of gastrointestinal haemorrhage, one case of perforation and one case of enterolith obstruction. All of these cases were secondary to jejunal diverticulosis and treated surgically. This was accompanied by a literature search to identify the different modalities for diagnosis and treatment of this condition. JD is rare and may lead to a diagnostic delay. Awareness of the wide spectrum of potential complications can prevent this delay.Vishal Arun Patel Helen Jefferis Ben Spiegelberg Quamar Iqbal Ashish Prabhudesai Simon Harris 2008World Journal of Gastroenterology2008,14,38:4
7Machine learning models compared to existing criteria for noninvasive prediction of endoscopic retrograde cholangiopancreatography-confirmed choledocholithiasis显示文摘Background and aims:Noninvasive predictors of choledocholithiasis have generally exhibited marginal performance characteristics.We aimed to identify noninvasive independent predictors of endoscopic retrograde cholangiopancreatography(ERCP)-confirmed choledocholithiasis and accordingly developed predictive machine learning models(MLMs).Methods:Clinical data of consecutive patients undergoing first-ever ERCP for suspected chol-edocholithiasis from 2015 to 2019 were abstracted from a prospectively-maintained database.Multiple logistic regression was used to identify predictors of ERCP-confirmed choledocholithiasis.MLMs were then trained to predict ERCP-confirmed choledocholithiasis using pre-ERCP ultrasound(US)imaging only as well as using all available noninvasive imaging(US,computed tomography,and/or magnetic reso-nance cholangiopancreatography).The diagnostic performance of American Society for Gastrointestinal Endoscopy(ASGE)“high-likelihood”criteria was compared to MLMs.Results:We identified 270 patients(mean age 46 years,62.2%female,73.7%Hispanic/Latino,59%with noninvasive imaging positive for choledocholithiasis)with native papilla who underwent ERCP for suspected choledocholithiasis,of whom 230(85.2%)were found to have ERCP-confirmed chol-edocholithiasis.Logistic regression identified choledocholithiasis on noninvasive imaging(odds ratio(OR)¼3.045,P¼0.004)and common bile duct(CBD)diameter on noninvasive imaging(OR¼1.157,P¼0.011)as predictors of ERCP-confirmed choledocholithiasis.Among the various MLMs trained,the random forest-based MLM performed best;sensitivity was 61.4%and 77.3%and specificity was 100%and 75.0%,using US-only and using all available imaging,respectively.ASGE high-likelihood criteria demonstrated sensitivity of 90.9%and specificity of 25.0%;using cut-points achieving this specificity,MLMs achieved sensitivity up to 97.7%.Conclusions:MLMs using age,sex,race/ethnicity,presence of diabetes,fever,body mass index(BMI),total bilirubin,maximum CBD diameter,and choledocholithiasis on pre-ERCP noninvasive imaging predict ERCP-confirmed choledocholithiasis with good sensitivity and specificity and outperform the ASGE criteria for patients with suspected choledocholithiasis.Camellia Dalai John M Azizian Harry Trieu Anand Rajan Formosa C Chen Tien Dong Simon W Beaven James H.Tabibian 2021Liver Research2021,5,4:3
