| 1 | Percutaneous endoscopic gastrostomy:Indications,technique,complications and management显示文摘Percutaneous endoscopic gastrostomy(PEG)is the preferred route of feeding and nutritional support in patients with a functional gastrointestinal system who require long-term enteral nutrition.Besides its wellknown advantages over parenteral nutrition,PEG offers superior access to the gastrointestinal system over surgical methods.Considering that nowadays PEG tube placement is one of the most common endoscopic procedures performed worldwide,knowing its indications and contraindications is of paramount importance in current medicine.PEG tubes are sometimes placed inappropriately in patients unable to tolerate adequate oral intake because of incorrect and unrealistic understanding of their indications and what they can accomplish.Broadly,the two main indications of PEG tube placement are enteral feeding and stomach decompression.On the other hand,distal enteral obstruction,severe uncorrectable coagulopathy and hemodynamic instability constitute the main absolute contraindications for PEG tube placement in hospitalized patients.Although generally considered to be a safe procedure,there is the potential for both minor and major complications.Awareness of these potential complications,as well as understanding routine aftercare of the catheter,can improve the quality of care for patients with a PEG tube.These complications can generally be classified into three major categories:endoscopic technical difficulties,PEG procedure-related complications and late complications associated with PEG tube use and wound care.In this review we describe a variety of minor and major tube-related complications as well as strategies for their management and avoidance.Different methods of percutaneous PEG tube placement into the stomach have been described in the literature with the'pull'technique being the most common method.In the last section of this review,the reader is presented with a brief discussion of these procedures,techniques and related issues.Despite the mentioned PEG tube placement complications,this procedure has gained worldwide popularity as a safe enteral access for nutrition in patients with a functional gastrointestinal system. | Ata A Rahnemai-Azar Amir A Rahnemaiazar Rozhin Naghshizadian Amparo Kurtz Daniel T Farkas | 2014 | World Journal of Gastroenterology2014，20，24： | 38 |
| 2 | Rubber band ligation for 750 cases of symptomatic hemorrhoids out of 2200 cases显示文摘AIM: To study the results for the treatment of symptomatic hemorrhoids using rubber band ligation (RBL) method. METHODS: A retrospective study for 750 patients who came to the colorectal unit from June, 1998 to September, 2006, data was retrieved from archived fi les. RBL was performed using the Mc Gown applicator on an outpatient basis. The patients were asked to return to out-patient clinic for follow up at 2 wk, 1 mo, 6 mo and through telephone call every 6 mo for 2 years). RESULTS: After RBL, 696 patients (92.8%) were cured with no difference in outcome for second or third degree hemorrhoids (P = 0.31). Symptomatic recurrence was detected in 11.04% after 2 years. A total of 52 patients (6.93%) had 77 complications from RBL which required no hospitalization. Complications were pain, rectal bleeding and vaso-vagal symptoms(4.13%, 4.13% and 1.33% of patients, respectively). At 1 mo there were a significant improvement in mean SF-36 scores over baseline in five items, while after 2 years there were improvement in all items over baseline, but not significant. No significant manometeric changes after band ligation. CONCLUSION: RBL is a simple, safe and effective method for treating symptomatic second and third degree hemorrhoids as an out patient procedure with signifi cant improvement in quality of life. RBL doesn't alter ano-rectal functions. | Ayman M El Nakeeb Amir A Fikry Waleed H Omar Elyamani M Fouda Tito A El Metwally Hosam E Ghazy Sabry A Badr Mohmed Y Abu Elkhar Salih M Elawady Hisham H Abd Elmoniam Waiel W Khafagy Mosaad M Morshed Ramadan E El Lithy Mohamed E Farid | 2008 | World Journal of Gastroenterology2008，14，42： | 24 |
| 3 | Stroke mechanisms and outcomes of isolated symptomatic basilar artery stenosis显示文摘background While diffuse atherosclerotic disease affecting the posterior circulation has been described extensively,the prevalence,natural history and angiographic characteristics of isolated symptomatic basilar artery stenosis(ISBAS)remain unknown.Methods We reviewed our prospective institutional database to identify patients with≥50% symptomatic basilar artery(BA)stenosis without significant atherosclerotic burden in the vertebral or posterior cerebral arteries.Stroke mechanism,collateral circulation,and degree and length of stenosis were analysed.The primary outcome was time from index event to new transient ischaemic attack(TIA),acute ischaemic stroke(AIS)or death.Other outcome variables included modified Rankin Scale(mRS)score on discharge and last follow-up.results Of 6369 patients with AIS/TIA,91(1.43%)had ISBAS.Seventy-three(80.2%)patients presented with AIS and 18(19.8%)with TIA.Twenty-nine(31.9%)were women and the median age was 66.8±13.6 years.The mean follow-up time was 2.7 years.The most common stroke mechanism was artery-to artery thromboembolism(45.2%),followed by perforator occlusion(28.7%)and flow-dependent/hypoperfusion(15.1%).The percentage of stenosis was lower in patients who had favourable outcome compared with those with mRS 3-6 on discharge(78.3±14.3 vs 86.9±14.5,p=0.007).Kaplan-Meier curves showed higher recurrence/death rates in patients with≥80% stenosis,mid-basilar location and poor collateral circulation.Approximately 13% of patients with ISBAS presented with complete BA occlusion.Conclusion ISBAS is an uncommon(1.43%)cause of TIA and AIS.Men in their 60s are mostly affected,and artery-to artery embolism is the most common stroke mechanism.Mid-basilar location,≥80% stenosis and poor collateral circulation are important factors associated with worse prognosis. | Edgar A Samaniego Amir Shaban Santiago Ortega-Gutierrez Jorge A Roa David M Hasan Colin Derdeyn Biyue Dai Harold Adams Enrique Leira | 2019 | Stroke & Vascular Neurology2019，4，4： | 10 |
| 4 | Carcinoma in situ in a 7 mm gallbladder polyp: Time to change current practice?显示文摘Detection of polypoid lesions of the gallbladder is increasing in conjunction with better imaging modalities. Accepted management of these lesions depends on their size and symptomatology. Polyps that are symptomatic and/or greater than 10 mm are generally removed, while smaller, asymptomatic polyps simply monitored. Here, a case of carcinoma-in-situ is presented in a 7 mm gallbladder polyp. A 25-year-old woman, who had undergone a routine cholecystectomy, was found to have an incidental 7 mm polyp containing carcinoma in situ. She had few to no risk factors to alert to her condition. There are few reported cases of cancer transformation in gallbladder polyps smaller than 10 mm reported in the literature. The overwhelming consensus, barring significant risk factors for cancer being present, is that such lesions should be monitored until they become symptomatic or develop signs suspicious for malignancy. In our patient's case this could have led to the possibility of missing a neoplastic lesion, which could then have gone on to develop invasive cancer. As gallbladder carcinoma is an aggressive cancer, this may have led to a tragic outcome. | David Kasle Amir A Rahnemai-Azar Shahida Bibi Vinaya Gaduputi Brian F Gilchrist Daniel T Farkas | 2015 | World Journal of Gastrointestinal Endoscopy2015，7，9： | 8 |
| 5 | Organosolv Lignin for Non-Isocyanate Based Polyurethanes (NIPU) as Wood Adhesive显示文摘A non-isocyanate-based polyurethane(NIPU)wood adhesive was produced from organosolv lignin,which is a bio-sourced raw material,available in large quantities and produced as a by-product of the paper industry.The formulation of this new lignin-based NIPU adhesive,which is presented,was chemically characterised by Matrix-Assisted Laser Desorption Ionization Time of Flight(MALDI ToF)mass spectrometry and by Fourier Transform Infra-Red(FTIR)spectrometry analyses.The oligomers formed were determined and showed that the three species involved in the NIPU adhesive preparation were formed by the co-reaction of the three reagents used:lignin,dimethyl carbonate,and hexamethylene diamine.Linear and branched structures were both identi-fied.Mechanical properties of the adhesive were determined using the Automated Bonding Evaluation System(ABES)and internal bond(IB)strength test of the laboratory particleboard bonded with it.The adhesive has shown satisfactory mechanical properties after hot pressing at 230℃.Such a temperature is used industrially in the most modern particleboard factories,but since it is hardly feasible for more conventional wood bonding equipment,the reactivity of the NIPU adhesive was successfully increased with the addition of a small percentage of a silane coupling agent.With the addition of the silane,the proposed NIPU adhesive could also be used at a hot-pressing temperature lower than 200℃. | Jaša Saražin Antonio Pizzi Siham Amirou Detlef Schmiedl MilanŠernek | 2021 | Journal of Renewable Materials2021，9，5： | 4 |
| 6 | Overexpression of fibrinogen-like protein 2 protects against T cell-induced colitis显示文摘AIM To determine the effect of overexpression of fibrinogenlike protein 2(FGL2) on regulatory T cell(Treg) and effector T(Teff) cell function on T cell-induced colitis in Rag1-/-mice.METHODS Treg and Teff cells from fgl2-/-, fgl2+/+, and fgl2 Tg mice were purified by FACS. They were studied in vitro for immunosuppressive activity and cell proliferation and in vivo for their effects on the development and prevention of T cell-induced colitis in Rag1-/-mice. RESULTS In vitro, fgl2 Tg Treg had enhanced immunosuppressive activity, and fgl2 Tg Teff had reduced proliferation to alloantigen stimulation. Transfer of Teff from C57Bl/6J mice(fgl2+/+) into Rag1-/-mice produced both clinical and histologic colitis with dense infiltrates of CD3+ T cells, crypt abscesses and loss of goblet cells. Fgl2 Tg Treg prevented the development of T cell-induced colitis, whereas fgl2+/+ and fgl2-/-Treg were only partially protective. In mice that received fgl2 Tg Treg, the ratio of Foxp3+ to CD3+ cells was increased both in the colon and in mesenteric lymph nodes, and Teff cell proliferation as determined by staining with Ki67 was reduced. Teff cells from fgl2 Tg mice did not produce colitis. CONCLUSION Here we show that fgl2 Tg Teff are hypoproliferative and do not induce colitis. We further demonstrate that fgl2 Tg Treg prevent colitis in contrast to fgl2+/+ Treg, which were only partially protective. These studies collectively provide a rationale for exploring the use of FGL2 or Treg expressing high levels of FGL2 in the treatment of inflammatory bowel disease. | Agata Bartczak Jianhua Zhang Oyedele Adeyi Achiya Amir David Grant Reginald Gorczynski Nazia Selzner Andrzej Chruscinski Gary A Levy | 2017 | World Journal of Gastroenterology2017，23，15： | 2 |
| 7 | Frequency of diabetic retinopathy and associated risk factors in Khartoum,Sudan:population based study显示文摘AIM: To assess the frequency and associated risk factors of diabetic retinopathy among Sudanese individuals with diabetes attending Makka Eye complex in Khartoum, Sudan. METHODS: The cross sectional hospital based study recruited 316 individuals with diabetes from Makkah Eye Complex Retina Clinic. Standard questionnaire was used to collect demographic data, medical history and life style characteristics. Blood samples were taken to measure Hb A1 c and lipid profile. Fundus and slit lamp examination were performed for screening of diabetic retinopathy.RESULTS: Among 316 participants, 187(59.2%) were males and 129(40.8%) were females. The mean age of participants was 58.7±10.5y. The overall frequency of retinopathy was 261(82.6%). The percentages of the total participants with proliferative diabetic retinopathy(PDR) were 126(39.9%) and non-proliferative diabetic retinopathy(NPDR) were 135(42.7%). Importantly, duration of diabetes mellitus(DM)(72.2% of more than 10y), being on oral hypoglycaemic drugs(versus insulin), and hypertension were all significant risk factors for diabetic retinopathy(P=0.00, 0.01 and 0.00 respectively). Complications ofdiabetes like diabetic foot(17.7%), history of amputation(6.7%) and clinically significant macular edema(CSME)(47.4%) of the eyes were all significant risk factors(P<0.05). Logistic regression analysis showed that duration of diabetes, hypertension and CSME were found to be absolute risk factors(P=0.007, 0.003 and 0.000 respectively). Duration of DM of more than 10 y have more than double risk(OR=2.8), while having hypertension triples the risk of retinopathy(OR=3.1).CONCLUSION: High rates of diabetic retinopathy are noted among individuals with diabetes attending Makkah Eye hospital in capital Khartoum. Urgent strategies are needed to monitor and treat hypertension and optimize diabetes control in individuals with diabetes. More investment in diabetes services is urgently needed. | Einas S Elwali Ahmed O Almobarak Mona A Hassan Amir A Mahmooud Heitham Awadalla Mohamed H Ahmed | 2017 | International Journal of Ophthalmology(English edition)2017，10，6： | 2 |

| 9 | Inter-ethnic marriages and severity of coronary artery disease:A multicenter study of Arabian Gulf States显示文摘AIM To assess the association of inter-ethnic vs intra-ethnic marriage with severity of coronary artery disease(CAD) in men undergoing angiography.METHODS We conducted a prospective multicenter,multi-ethnic,cross sectional observational study at five hospitals in Saudi Arabia and the United Arab Emirates,in which we used logistic regression analysis with and without adjustment for baseline differences. RESULTS Data were collected for 1068 enrolled patients undergoing coronary angiography for clinical indications during the period of April 1^(st),2013 to March 30^(th),2014. Ethnicities of spouses were available only for male patients. Of those enrolled,687 were married men and constituted the cohort for the present analysis. Intra-ethnic marriages were reported in 70% and inter-ethnic marriages in 30%. After adjusting for baseline differences,interethnic marriage was associated with lower odds of having significant CAD [adjusted odds ratio 0.52(95%CI:0.33,0.81)] or multi-vessel disease(MVD) [adjusted odds ratio 0.57(95%CI:0.37,0.86)]. The adjusted association with left main disease showed a similar trend,but was not statistically significant [adjusted odds ratio 0.74(95%CI:0.41,1.32)]. The association between interethnic marriage and the presence of significant CAD and MVD was not modified by number of concurrent wives(P interaction > 0.05 for both).CONCLUSION Among married men undergoing coronary angiography,inter-ethnic,as compared to intra-ethnic,marriage is associated with lower odds of significant CAD and MVD. | Amin Daoulah Salem Al-kaabi Amir Lotfi Mushabab Al-Murayeh S Ali Nasseri Waleed Ahmed Salah N Al-Otaibi Mohamed N Alama Osama E Elkhateeb Amy J Plotkin Majed M Malak Khalid Alshali Mohamed Hamzi Saleh Al Khunein Mohammed Abufayyah Alawi A Alsheikh-Ali | 2017 | World Journal of Cardiology2017，9，4： | 2 |
