| 1 | Ampullary carcinoma:Effect of preoperative biliary drainage on surgical outcome显示文摘AIM: To evaluate the influence of preoperative biliary drainage on morbidity and mortality after surgical resection for ampullary carcinoma. METHODS: We analyzed retrospectively data for 82 patients who underwent potentially curative surgery for ampullary carcinoma between September 1993 and July 2007 at the Singapore General Hospital, a tertiary referral hospital. Diagnosis of ampullary carcinoma was confirmed histologically. Thirty-five patients underwent preoperative biliary drainage (PBD group), and 47 were not drained (non-PBD group). The mode of biliary drainage was endoscopic retrograde cholangiopancreatography (n = 33) or percutaneous biliary drainage (n = 2). The following parameters were analyzed: wound infection, intra-abdominal abscess, intra-abdominal or gastrointestinal bleeding, septicemia, biliary or pancreatic leakage, pancreatitis, gastroparesis, and re-operation rate. Mortality was assessed at 30 d (hospital mortality) and also longterm. The statistical endpoint of this study was patient survival after surgery. RESULTS: The groups were well matched for demographic criteria, clinical presentation and operative characteristics, except for lower hemoglobin in the non-PBD group (10.9 ± 1.6 vs 11.8 ± 1.6 in the PBD group).Of the parameters assessing postoperative morbidity, incidence of wound infection was signif icantly less in the PBD than the non-PBD group [1 (2.9%) vs 12 (25.5%)]. However, the rest of the parameters did not differ signif icantly between the groups, i.e. sepsis [10 (28.6%) vs 14 (29.8%)], intra-abdominal bleeding [1 (2.9%) vs 5 (10.6%)], intra-abdominal abscess [1 (2.9%) vs 8 (17%)], gastrointestinal bleeding [3 (8.6%) vs 5 (10.6%)], pancreatic leakage [2 (5.7%) vs 3 (6.4%)], biliary leakage [2 (5.7%) vs 3 (6.4%)], pancreatitis [2 (5.7%) vs 2 (4.3%)], gastroparesis [6 (17.1%) vs 10 (21.3%)], need for blood transfusion [10 (28.6%) vs 17 (36.2%)] and re-operation rate [1 (2.9%) vs 5 (10.6%)]. There was no early mortality in either group. Median survival was 44 mo (95% CI: 34.2-53.8) in the PBD group and 41 mo (95% CI: 27.7-54.3; P = 0.86) in the non-PBD group. CONCLUSION: Biliary drainage before surgery for ampullary cancer significantly reduced postoperative wound infection. Overall mortality was not influenced by preoperative drainage. | Sheikh Anwar Abdullah Tarun Gupta Khairul Azhar Jaafar Yaw Fui Alexander Chung London Lucien Peng Jin Ooi Steven Joseph Mesenas | 2009 | World Journal of Gastroenterology2009，15，23： | 16 |

| 7 | Aspect-Based Sentiment Analysis for Social Multimedia:A Hybrid Computational Framework显示文摘People utilize microblogs and other social media platforms to express their thoughts and feelings regarding current events,public products and the latest affairs.People share their thoughts and feelings about various topics,including products,news,blogs,etc.In user reviews and tweets,sentiment analysis is used to discover opinions and feelings.Sentiment polarity is a term used to describe how sentiment is represented.Positive,neutral and negative are all examples of it.This area is still in its infancy and needs several critical upgrades.Slang and hidden emotions can detract from the accuracy of traditional techniques.Existing methods only evaluate the polarity strength of the sentiment words when dividing them into positive and negative categories.Some existing strategies are domain-specific.The proposed model incorporates aspect extraction,association rule mining and the deep learning technique Bidirectional EncoderRepresentations from Transformers(BERT).Aspects are extracted using Part of Speech Tagger and association rulemining is used to associate aspects with opinion words.Later,classification was performed using BER.The proposed approach attained an average of 89.45%accuracy,88.45%precision and 85.98%recall on different datasets of products and Twitter.The results showed that the proposed technique achieved better than state-of-the-art sentiment analysis techniques. | Muhammad Rizwan Rashid Rana Saif Ur Rehman Asif Nawaz Tariq Ali Azhar Imran Abdulkareem Alzahrani Abdullah Almuhaimeed | 2023 | Computer Systems Science & Engineering2023，46，8： | 0 |
| 8 | Shape Effect of Nanoparticles on Nanofluid Flow Containing Gyrotactic Microorganisms显示文摘In this paper,we discussed the effect of nanoparticles shape on bioconvection nanofluid flow over the vertical cone in a permeable medium.The nanofluid contains water,Al2O3 nanoparticles with sphere(spherical)and lamina(non-spherical)shapes and motile microorganisms.The phenomena of heat absorption/generation,Joule heating and thermal radiation with chemical reactions have been incorporated.The similarity transformations technique is used to transform a governing system of partial differential equations into ordinary differential equations.The numerical bvp4c MATLAB program is used to find the solution of ordinary differential equations.The interesting aspects of pertinent parameters on mass transfer,energy,concentration,and density of themotilemicroorganisms’profiles are computed and discussed.Our analysis depicts that the performance of sphere shape nanoparticles in the form of velocity distribution,temperature distribution,skin friction,Sherwood number and Motile density number is better than lamina(non-spherical)shapes nanoparticles. | Umair Rashid Azhar Iqbal Abdullah M.Alsharif | 2023 | Computer Modeling in Engineering & Sciences2023，，1： | 0 |
| 9 | Proportion of thyroid cancer and other cancers in the democratic republic of Congo显示文摘BACKGROUND Cancer diagnosis is increasing around the world and in the Democratic Republic of the Congo(DRC).The proportion of thyroid cancer has increased over the past three decades.There are very few studies on cancer epidemiology,and in particular on thyroid cancer in the DRC.AIM To establish the most recent proportion of thyroid cancer in the DRC compared to other cancers.METHODS This is a retrospective and descriptive study of 6106 consecutive cancer cases listed in the pathological registers of 4 Laboratories in the city of Kinshasa.This study included all cancer cases recorded in the registers between 2005 and 2019.RESULTS From a sample of 6106 patients,including all cancer types,68.3%cases were female and 31.7%were male.Breast and cervical cancer were the most common types of cancer in women and,prostate and skin cancer were the most common types in men.Thyroid cancer was sixth in proportion in women and eleventh in men compared to all cancers.Papillary carcinoma was the most common of thyroid cancers.Rare cancers such as anaplastic and medullary thyroid carcinomas had a proportion of 7%and 2%,respectively.CONCLUSION Newer diagnostic tools led to a surge in cancer diagnoses in the DRC.Thyroid cancer has more than doubled its proportion over the last several decades in the country. | John Bukasa-Kakamba Ayrton I Bangolo Pascal Bayauli Branly Mbunga Francis Iyese Aliocha Nkodila Ali Atoot Gaurav Anand Stacy H Lee Maimona Chaudhary Pamela Q Fernandes Hari PSS Mannam Adithya Polavarapu Merajunissa Merajunnissa Abdullah Azhar Mohan N Alichetty Gauravdeep Singh Georgemar V Arana Jr Imranjot Sekhon Manbir Singh JoséD Rodriguez-Castro Adam Atoot Simcha Weissman Jean Rene M’buyamba | 2023 | World Journal of Experimental Medicine2023，13，3： | 0 |
