1Epinephrine injection therapy versus a combination of epinepnrine injection and endoscopic hemoclip in the treatment of bleeding ulcers显示文摘AIM: To assess the efficacy of hemoclip application in combination with epinephrine injection in the treatment of bleeding peptic ulcers and to compare the clinical outcomes between patients treated with such a combination therapy and those treated with epinephrine injection alone.METHODS: A total of 293 patients (211 males, 82females) underwent endoscopic therapy for bleeding peptic ulcers. Of these, 202 patients (152 males, 50females) received epinephrine injection therapy while 91patients (59 males, 32 females) received combination therapy. The choice of endoscopic therapy was made by the endoscopist. Hemostatic rates, rebleeding rates, need for emergency surgery and 30-d mortality were the outcome measures studied.RESULTS: Patients who received combination therapy were significantly older (mean age 66±16 years, range24-90 years) and more suffered from chronic renal failure compared to those who received epinephrine injection therapy alone (mean age 61±17 years, range 21-89 years).Failure to achieve permanent hemostasis was 4% in the group who received epinephrine injection alone and 11%in the group who received combination therapy. When the differences in age and renal function between the two treatment groups were taken into account by multivariate analysis, the rates of initial hemostasis,rebleeding rates, need for surgery and 30-d mortality for both treatment options were not significantly different.CONCLUSION: Combination therapy of epinephrine injection with endoscopic hemoclip application is an effective method of achieving hemostasis in bleeding peptic ulcer diseases. However, superiority of combination therapy over epinephrine injection alone, could not be demonstrated.Tju-Siang Chua Kwong-Ming Fock Tay-Meng Ng Eng-Kiong Teo Jessica Yi-Lyn Tan Tiing-Leong Ang 2005World Journal of Gastroenterology2005,11,7:27
2Combined resection and radiofrequency ablation for multifocal hepatocellular carcinoma: Prognosis and outcomes显示文摘AIM: To analyze the combined treatment of resection and intraoperative radiofrequency ablation (RFA) for multifocal hepatocellular carcinoma in terms of prognosis and surgical outcomes.METHODS: This study was a retrospective case comparison study using prospectively collected data. The study covered the period from April 2001 to December 2006. The data of 200 patients with histologically confirmed hepatocellular carcinoma were reviewed. Nineteen patients (17 men and 2 women) having received resection in combination with RFA were chosen as subjects of the study (the combination group). Fiftyfour patients (43 men and 11 women) having received resection alone were selected for comparison (the resection group). The two groups matched tumor number and tumor size, and all the patients in the two groups displayed no tumor rupture, major vascular involvement and distant metastasis. Their demographics, preoperative assessment, disease recurrence patterns, overall survival and diseasefree survival were compared.RESULTS: In the combination group, the medianage was 65 years (range, 3477 years), the median tumor number was 3 (range, 29), and the median tumor size was 6 cm (range, 1.214 cm). In the resection group, the median age was 51.5 years (range, 2780 years, P = 0.003), the median tumor number was 3 (range, 29, P = 0.574), and the median tumor size was 6 cm (range, 114 cm, P = 0.782). The two groups were similar in characteristics of tumors and comorbidities, and had comparable results in preoperative liver function tests. All patients had ChildPugh class A status. Bilobar involvement occurred in 14 patients (73.6%) in the combination group and 3 patients (5.5%) in the resection group (P = 0.04). Six patients (32%) in the combination group and 35 patients (65%) in the resection group underwent major hepatectomy. Thirteen patients (68%) in the combination group and 19 patients (35%) in the resection group underwent minor hepatectomy (P = 0.012). The combination group had fewer major resections (32% vs 65%, P = 0.012), less blood loss (400 vs 657 mL, P = 0.007), shorter operation time (270 vs 400 min, P = 0.001), and shorter hospital stay (7 vs 8.5 d, P = 0.042). The two groups displayed no major differences in surgical complications (15.8% vs 31.5%, P = 0.24), disease recurrence (63.2% vs 50%, P = 0.673), hospital mortality (5.3% vs 5.6%, P = 1), and overall survival (53 vs 44.5 mo, P = 0.496).CONCLUSION: Safe and effective for selected patients with multifocal hepatocellular carcinoma, the combination of resection and intraoperative RFA widens the applicability of surgical intervention for the disease.Tan To Cheung Kelvin K Ng Kenneth S Chok See Ching Chan Ronnie T Poon Chung Mau Lo Sheung Tat Fan 2010World Journal of Gastroenterology2010,16,24:14
3Application of constructed wetlands for wastewater treatment in tropical and subtropical regions(2000–2013)显示文摘Constructed wetlands(CWs) have been successfully used for treating various wastewaters for decades and have been identified as a sustainable wastewater management option for developing countries. With the goal of promoting sustainable engineered systems that support human well-being but are also compatible with sustaining natural(environmental)systems, the application of CWs has become more relevant. Such application is especially significant for developing countries with tropical climates, which are very conducive to higher biological activity and productivity, resulting in higher treatment efficiencies compared to those in temperate climates. This paper therefore highlights the practice,applications, and research of treatment wetlands under tropical and subtropical conditions since 2000. In the present review, removal of biochemical oxygen demand(BOD) and total suspended solid(TSS) was shown to be very efficient and consistent across all types of treatment wetlands. Hybrid systems appeared more efficient in the removal of total suspended solid(TSS)(91.3%), chemical oxygen demand(COD)(84.3%), and nitrogen(i.e.,80.7% for ammonium(NH)4-N, 80.8% for nitrate(NO)3-N, and 75.4% for total nitrogen(TN))as compared to other wetland systems. Vertical subsurface flow(VSSF) CWs removed TSS(84.9%), BOD(87.6%), and nitrogen(i.e., 66.2% for NH4-N, 73.3% for NO3-N, and 53.3% for TN)more efficiently than horizontal subsurface flow(HSSF) CWs, while HSSF CWs(69.8%)showed better total phosphorus(TP) removal compared to VSSF CWs(60.1%). Floating treatment wetlands(FTWs) showed comparable removal efficiencies for BOD(70.7%),NH4-N(63.6%), and TP(44.8%) to free water surface(FWS) CW systems.Dong-Qing Zhang K.B.S.N.Jinadasa Richard M.Gersberg Yu Liu Soon Keat Tan Wun Jern Ng 2015Journal of Environmental Sciences2015,27,4:14
4A comparison of the clinical, demographic and psychiatric profiles among patients with erosive and non-erosive reflux disease in a multi-ethnic Asian country显示文摘AIM: To examine the clinical spectrum of gastroesophageal reflux disease (GERD) and compare erosive (ERD) with non-erosive (NERD) in terms of clinical, demographic and psychiatric profiles.METHODS: Patients with reflux symptoms were enrolled and stratified to NERD and ERD after endoscopy (LA classification). Patients with ERD presenting with dyspepsia were included. Patients on proton pump inhibitors (PPI) or H2 receptor antagonists before endoscopy were excluded.Demographic data, Helicobacter pylori (H pylon) status and presence of minor psychiatric morbidity (based on General Health Questionnaire-28) were analyzed. RESULTS: Among 690 patients screened, 533 were eligible for analysis (male to female ratio: 3:2; Chinese: 75.4%; Malay: 9.8%; Indian: 14.8%). Clinical spectrum of GERD: N: 40.5%; A: 46%; B: 9.2%; C: 2.1%; D: 0.6%; Barrett's esophagus: 1.7%. Compared to patients with NERD, patients with ERD were significantly older (45 vs 39.4 years), more likely to be male (64.4% vs 53.7%),tended to smoke (19.6% vs 9.7%), less likely to haveminor psychiatric morbidity (26.4 vs 46.7%) and were more likely to respond to PPI (79.7 vs66.8%). There wasalso a trend towards a higher BMI (24.5 vs 23.5). Race,alcohol consumption and H pylori status were not significant.On multivariate analysis, age and presence of minor psychiatric morbidity remained with significant differences. CONCLUSION: The majority of patients who have typical symptoms of GERD have NERD or mild erosive reflux disease. Compared to patients with erosive reflux disease, patients with NERD were younger and had a higher prevalence of minor psychiatric morbidity.Tiing-Leong Ang Kwong-Ming Fock Tay-Meng Ng Eng-Kiong Teo Tju-Siang Chua Jessica Tan 2005World Journal of Gastroenterology2005,11,23:12

6Overview of multiplex immunohistochemistry/immunofluorescence techniques in the era of cancer immunotherapy显示文摘Conventional immunohistochemistry(IHC)is a widely used diagnostic technique in tissue pathology.However,this technique is associated with a number of limitations,including high inter-observer variability and the capacity to label only one marker per tissue section.This review details various highly multiplexed techniques that have emerged to circumvent these constraints,allowing simultaneous detection of multiple markers on a single tissue section and the comprehensive study of cell composition,cellular functional and cell-cell interactions.Among these techniques,multiplex Immunohistochemistry/Immunofluorescence(mIHC/IF)has emerged to be particularly promising.mIHC/IF provides high-throughput multiplex staining and standardized quantitative analysis for highly reproducible,efficient and cost-effective tissue studies.This technique has immediate potential for translational research and clinical practice,particularly in the era of cancer immunotherapy.Wei Chang Colin Tan Sanjna Nilesh Nerurkar Hai Yun Cai Harry Ho Man Ng Duoduo Wu Yu Ting Felicia Wee Jeffrey Chun Tatt Lim Joe Yeong Tony Kiat Hon Lim 2020Cancer Communications2020,40,4:11

8Rabeprazole vs esomeprazole in non-erosive gastro-esophageal reflux disease: A randomized, double-blind study in urban Asia显示文摘AIM:Gastro-esophageal reflux disease (GERD) is becoming increasingly common in Asia. Data on the efficacy of proton pump inhibitors in patients with non-erosive GERD (NERD)in Asia is lacking. This double-blind study compared the efficacy and safety of rabeprazole with esomeprazole in relief of symptoms in patients with NERD.METHODS: One hundred and thirty-four patients with reflux symptoms of NERD and normal endoscopy were randomized to receive rabeprazole 10 mg or esomeprazole 20 mg once daily for 4 wk. Symptoms were recorded in a diary and changes in severity of symptoms noted.RESULTS: At 4 wk of treatment, rabeprazole 10 mg and esomeprazole 20 mg were comparable with regards to the primary endpoint of time to achieve 24-h symptomfree interval for heartburn 8.5 d vs9 d and regurgitation 6 d vs 7.5 d. Rabeprazole and esomeprazole were also similarly efficacious in term of patient's global evaluation with 96% of patients on rabeprazole and 87.9% of patients on esomeprazole, reporting that symptoms improved(P=NS). Satisfactory relief of day- and night-time symptoms was achieved in 98% of patients receiving rabeprazole and 81.4% of patients receiving esomeprazole. Adverse events were comparable in both groups (P = NS).CONCLUSION: Rabeprazole 10 mg has a similar efficacy and safety profile in Asians with NERD as esomeprazole 20 mg. Further study is necessary to investigate whether the small differences between the two drugs seen in this study are related to the improved pharmacodynamicpro perties of rabeprazole. Both drugs were well tolerated.KM Fock EK Teo TL Ang TS Chua TM Ng YL Tan 2005World Journal of Gastroenterology2005,11,20:8

10Gastric peritoneal carcinomatosis-a retrospective review显示文摘AIM To characterize patients with gastric peritoneal carcinomatosis(PC) and their typical clinical and treatment course with palliative systemic chemotherapy as the current standard of care.METHODS We performed a retrospective electronic chart review of all patients with gastric adenocarcinoma with PC diagnosed at initial metastatic presentation between January 2010 and December 2014 in a single tertiary referral centre.RESULTS We studied a total of 271 patients with a median age of 63.8 years and median follow-up duration of 5.1 mo. The majority(n = 217, 80.1%) had the peritoneum as the only site of metastasis at initial presentation. Palliative systemic chemotherapy was eventually planned for 175(64.6%) of our patients at initial presentation, of which 171 were initiated on it. Choice of first-line regime was in accordance with the National Comprehensive Cancer Network Guidelines for Gastric Cancer Treatment. Thesepatients underwent a median of one line of chemotherapy, completing a median of six cycles in total. Chemotherapy disruption due to unplanned hospitalizations occurred in 114(66.7%), while cessation of chemotherapy occurred in 157(91.8%), with 42 cessations primarily attributable to PC-related complications. Patients who had initiation of systemic chemotherapy had a significantly better median overall survival than those who did not(10.9 mo vs 1.6 mo, P < 0.001). Of patients who had initiation of systemic chemotherapy, those who experienced any disruptions to chemotherapy due to unplanned hospitalizations had a significantly worse median overall survival compared to those who did not(8.7 mo vs 14.6 mo, P < 0.001).CONCLUSION Gastric PC carries a grim prognosis with a clinical course fraught with disease-related complications which may attenuate any survival benefit which palliative systemic chemotherapy may have to offer. As such, investigational use of regional therapies is warranted and required validation in patients with isolated PC to maximize their survival outcomes in the long run.Hwee Leong Tan Claramae Shulyn Chia Grace Hwei Ching Tan Su Pin Choo David Wai-Meng Tai Clarinda Wei Ling Chua Matthew Chau Hsien Ng Khee Chee Soo Melissa Ching Ching Teo 2017World Journal of Gastrointestinal Oncology2017,9,3:6
11Expanding the scope of application of user innovation theorydA case study of the civil-military integration project in China显示文摘The focus of scholars studying user innovation has been restricted to the interaction between companies and individual users,and how companies can unilaterally exploit values from the value chain between companies and users.We argue that the value chain between the user and manufacturer should be a bilateral value chain in which both the user and manufacturer can conduct their own innovations and provide greater value to the whole value chain.In this paper,using examples from China's civil-military integration project,we took a step forward to apply the user innovation theory in the explanation of inter-sector technological value transfer.The main theoretical contribution of this paper is the expansion of the scope of application of the user innovation theory to inter-sector level research.Studying cases from China's civil-military integration project,we found that the concepts of user and innovator become blurred when we study the phenomenon across time.When we go beyond individual user and manufacturer and shift the focus of our discussion to the level of inter-sector technological value transfer,we will find that it is possible for organizational agents at large to be both users and innovators of technology.Jhony Choon Yeong Ng Karen Kai Wen Song Qingmei Tan 2018International Journal of Innovation Studies2018,2,1:6
12Clinical utility,safety and tolerability of capsule endoscopy in urban Southeast Asian population显示文摘AIM:Capsule endoscopy has demonstrated its clinical utility in the evaluation of small bowel pathology in several Western studies. In this prospective study, we aimed to determine the clinical utility, safety and tolerability of capsule endoscopy in the evaluation of suspected small bowel disease in an urban Southeast Asian population.METHODS: We used the given (M2A) capsule endoscopy system in 16 consecutive patients with suspected small bowel pathology. In 9 patients the indication was obscure gastrointestinal bleeding, while in 6 patients it was to determine the extent of small bowel involvement in Crohn's disease. One patient underwent capsule endoscopy for evaluation of chronic abdominal pain. Patient's tolerability to the procedure was evaluated by standardized questionnaires and all patients were reviewed at one week to ensure that the capsule had been excreted without any adverse events.RESULTS: Abnormal findings were present in 8 patients (50%). The cause of obscure gastrointestinal bleeding was determined in 5 out of 9 patients. Findings included 2 cases of angiodysplasia, 2 cases of jejunal ulcers and 1 case of both angiodysplasia and jejunal ulcer. One patient had small bowel erosions and foci of erythema of doubtful significance.Ileal lesions were diagnosed in 2 out of 6 patients with Crohn's disease. Capsule endoscopy was well tolerated by all patients. One patient with Crohn's disease had a complication of capsule retention due to terminal ileum stricture. The capsule eventually passed out spontaneously after 1 month.CONCLUSION: Our study, which represented the first Asian series, further confirms the diagnostic utility, safety and tolerability of wireless capsule endoscopy.Tiing-Leong Ang Kwong-Ming Fock Tay-Meng Ng Eng-Kiong Teo Yi-Lyn Tan 2003World Journal of Gastroenterology2003,9,10:6
13Double-row repair of rotator cuff tears: Comparing tendon contact area between techniques显示文摘BACKGROUND In rotator cuff repair surgery,the double-row technique is widely performed.Studies have shown that with increased contact area and pressure between tendon and bone interface,better healing is promoted.AIM To assess the different suture configurations with the double-row technique and how this influences the contact area of the rotator cuff tendon to bone.METHODS This was a controlled laboratory study where identical tears were created in 24 fresh porcine shoulders over a 1.5 cm×2.5 cm infraspinatus insertion footprint.Double-row repair techniques,with 3 to 4-suture anchors in different configurations(2 medial,2 lateral vs 2 medial,1 lateral vs 1 medial,2 lateral),were employed for three control groups.Each group consisted of eight shoulders with identical repair configurations.Footprint contact areas of the repaired tendon against the tuberosity were determined using pressure sensitive Fujifilm placed between the tendon and tuberosity.RESULTS The mean contact area between tendon and insertion footprint from the imprinted Fujifilm was obtained using computer software.The contact area measured from a standard 4-suture anchor double row repair was 75.1±9.3 mm2,whereas areas obtained for the 2 lateral-1 medial and 2 medial-1 lateral anchor configurations were 72.9±5.2 mm2 and 75.0±4.9 mm2 respectively.No statistical significance was noted between the three groups.CONCLUSION In the technique of double-row repair,using a 3-suture anchor configuration may offer a non-inferior alternative to the standard 4-anchor construct in terms of efficacy.This may also result in overall cost reduction and shorter surgical time.Shao Hui Allan Ng Chung Hui James Tan 2020World Journal of Orthopedics2020,11,1:6
14A case of laparoscopic hepatectomy for recurrent hepatocellular carcinoma显示文摘Conventional hepatectomy is an effective way to treat hepatocellular carcinoma.However,it is invasive and stressful.The use of laparoscopy in hepatectomy,while technically demanding,reduces surgical invasiveness and stressfulness but still achieves complete resection with adequate margins.Compared with conventional hepatectomy,laparoscopic hepatectomy provides a better chance and situation for further surgery in the case of recurrence of hepatocellular carcinoma.Even aged patients can successfully endure repeated hepatectomy using laparoscopy,as shown in the present report.This report presents a case of repeated laparoscopic hepatectomy treating hepatocellular carcinoma and its recurrence in an aged patient having cirrhosis,a disease causing extra difficulty for performing laparoscopic hepatectomy.The report also describes techniques of the operation and displays characteristic results of laparoscopic hepatectomy such as smaller wounds,less blood loss,less pain,less scars and adhesion,shorter postoperative hospital stay,and faster recovery.Tan To Cheung Kelvin Kwok-chai Ng Ronnie Tung-ping Poon See Ching Chan Chung Mau Lo Sheung Tat Fan 2010World Journal of Gastroenterology2010,16,4:5

18Endoscopic submucosal dissection vs endoscopic mucosal resection for colorectal polyps:A meta-analysis and metaregression with single arm analysis显示文摘BACKGROUND Endoscopic submucosal dissection(ESD)has shown to be effective in management of colorectal neoplasm in the Asian countries,while its implementation in Western countries where endoscopic mucosal resection(EMR)is preferred is still debatable.AIM To compare the surgical,histological,and oncological outcomes between ESD and EMR in the treatment of colorectal polyps,with subgroup analysis comparing the efficacy of ESD and EMR between Japan and the rest of the world.METHODS Embase and Medline databases were searched from inception to October 2020 in accordance with PRISMA guidelines for studies comparing en bloc,complete resection,margin involvement,resection time,need for additional surgery,complications,and recurrence rate of ESD with EMR.RESULTS Of 281344 colorectal polyps from 21 studies were included.When compared to EMR,the pooled analysis revealed ESD was associated with higher en bloc and complete resection rate,and lower lateral margin involvement and recurrence.ESD led to increased procedural time,need for additional surgery,and perforation risk.No significant difference in bleeding risk was found between the two groups.Meta-regression analysis suggested only right colonic polyps correlated with an increased perforation risk in ESD.Confounders including polyp size and invasion depth did not significantly influence the en bloc and complete resection rate,bleeding risk and recurrence.In subgroup analysis,Japan performed better than the rest of the world in both ESD and EMR with perforation risk of 4%and 0.0002%,respectively,as compared to perforation risk of 8%and 1%,respectively,in reports coming from rest of the world.CONCLUSION ESD resulted in better resection outcomes and lower recurrence compared to EMR.With appropriate training,ESD is preferred over EMR as the first-line therapy for resection of colorectal polyps,without restricting to lesions greater than 20 mm and those with high suspicion of submucosal invasion.Xiong Chang Lim Kameswara Rishi Yeshayahu Nistala Cheng Han Ng Snow Yunni Lin Darren Jun Hao Tan Khek-Yu Ho Choon-Seng Chong Mark Muthiah 2021World Journal of Gastroenterology2021,27,25:4
19Point-to-face contact heterojunctions:Interfacial design of 0D nanomaterials on 2D g-C_(3)N_(4)towards photocatalytic energy applications显示文摘Green energy generation is an indispensable task to concurrently resolve fossil fuel depletion and environmental issues to align with the global goals of achieving carbon neutrality.Photocatalysis,a process that transforms solar energy into clean fuels through a photocatalyst,represents a felicitous direction toward sustainability.Eco-rich metal-free graphitic carbon nitride(g-C_(3)N_(4))is profiled as an attractive photocatalyst due to its fascinating properties,including excellent chemical and thermal stability,moderate band gap,visible light-active nature,and ease of fabrication.Nonetheless,the shortcomings of g-C_(3)N_(4)include fast charge recombination and limited surface-active sites,which adversely affect photocatalytic reactions.Among the modification strategies,point-to-face contact engineering of 2D g-C_(3)N_(4)with 0D nanomaterials represents an innovative and promising synergy owing to several intriguing attributes such as the high specific surface area,short effective charge-transfer pathways,and quantum confinement effects.This review introduces recent advances achieved in experimental and computational studies on the interfacial design of 0D nanostructures on 2D g-C_(3)N_(4)in the construction of point-to-face heterojunction interfaces.Notably,0D materials such as metals,metal oxides,metal sulfides,metal selenides,metal phosphides,and nonmetals on g-C_(3)N_(4)with different charge-transfer mechanisms are systematically discussed along with controllable synthesis strategies.The applications of 0D/2D g-C_(3)N_(4)-based photocatalysts are focused on solar-to-energy conversion via the hydrogen evolution reaction,the CO_(2)reduction reaction,and the N2 reduction reaction to evaluate the photocatalyst activity and elucidate reaction pathways.Finally,future perspectives for developing high-efficiency 0D/2D photocatalysts are proposed to explore potential emerging carbon nitride allotropes,large-scale production,machine learning integration,and multidisciplinary advances for technological breakthroughs.Xin-Quan Tan Sue-Faye Ng Abdul Rahman Mohamed Wee-Jun Ong 2022Carbon Energy2022,4,5:3
