| 1 | Endorectal ultrasonography versus phased-array magnetic resonance imaging for preoperative staging of rectal cancer显示文摘AIM: To compare the diagnostic accuracy of pelvic phased-array magnetic resonance imaging (MRI) and endorectal ultrasonography (ERUS) in the preoperative staging of rectal carcinoma. METHODS: Thirty-four patients (15 males, 19 females) with ages ranging between 29 and 75 who have biopsy proven rectal tumor underwent both MRI and ERUS examinations before surgery. All patients were evaluated to determine the diagnostic accuracy of depth of transmural tumor invasion and lymph node metastases. Imaging results were correlated with histopathological findings regarded as the gold standard and both modalities were compared in terms of predicting preoperative local staging of rectal carcinoma. RESULTS: The pathological T stage of the tumors was: pT1 in 1 patient, pT2 in 9 patients, pT3 in 21 patients and pT4 in 3 patients. The pathological N stage of the tumors was: pN0 in 19 patients, pN1 in 9 patients and pN2 in 6 patients. The accuracy of T staging for MRI was 89.70% (27 out of 34). The sensitivity was 79.41% and the specificity was 93.14%. The accuracy of T staging for ERUS was 85.29% (24 out of 34). The sensitivity was 70.59% and the specificity was 90.20%. Detection of lymph node metastases usingphased-array MRI gave an accuracy of 74.50% (21 out of 34). The sensitivity and specificity was found to be 61.76% and 80.88%, respectively. By using ERUS in the detection of lymph node metastases, an accuracy of 76.47% (18 out of 34) was obtained. The sensitivity and specificity were found to be 52.94% and 84.31%, respectively. CONCLUSION: ERUS and phased-array MRI are complementary methods in the accurate preoperative staging of rectal cancer. In conclusion, we can state that phased-array MRI was observed to be slightly superior in determining the depth of transmural invasion (T stage) and has same value in detecting lymph node metastases (N stage) as compared to ERUS. | Ahmet Mesrur Halefoglu Sadik Yildirim Omer Avlanmis Damlanur Sakiz Adil Baykan | 2008 | World Journal of Gastroenterology2008，14，22： | 35 |
| 2 | Gallbladder polyps: Factors affecting surgical decision显示文摘AIM: To determine the factors affecting the decision to perform surgery, and the efficiency of ultrasonography (USG) in detecting gallbladder polyps (GP). METHODS: Data for 138 patients who underwent cholecystectomy between 1996 and 2012 in our clinic with a diagnosis of GP were retrospectively analyzed. Demographic data, clinical presentation, principal symptoms, ultrasonographic and histopathological findings were evaluated. Patients were evaluated in individual groups according to the age of the patients (older or younger than 50 years old) and polyp size (bigger or smaller than 10 mm) and characteristics of the polyps (pseudopolyp or real polyps). χ 2 tests were used for the statistical evaluation of the data. RESULTS: The median age was 50 (26-85) years and 91 of patients were female. Of 138 patients who underwent cholecystectomy with GP diagnosis, only 99 had a histopathologically defined polyp; 77 of them had pseudopolyps and 22 had true polyps. Twenty-one patients had adenocarcinoma. Of these 21 patients, 11 were male, their median age was 61 (40-85) years and all malignant polyps had diameters > 10 mm (P< 0.0001). Of 138 patients in whom surgery were performed, 112 had ultrasonographic polyps with diameters < 10 mm. Of the other 26 patients who also had polyps with diameters > 10 mm, 22 had true polyps. The sensitivity of USG was 84.6% for polyps with diameters > 10 mm (P < 0.0001); however it was only 66% in polyps with diameters < 10 mm. CONCLUSION: The risk of malignancy was high in the patients over 50 years old who had single polyps with diameters > 10 mm. | Pinar Sarkut Sadik Kilicturgay Ali Ozer Ersin Ozturk Tuncay Yilmazlar | 2013 | World Journal of Gastroenterology2013，19，28： | 12 |
| 3 | EUS-guided drainage is more successful in pancreatic pseudocysts compared with abscesses显示文摘AIM: To compare the results for endoscopic ultrasound (EUS)-guided drainage of clear fluid pancreatic pseudocysts with the results for abscess drainage. METHODS: All patients referred for endoscopic drainage of a fluid collection were prospectively included. The outcome was recorded. RESULTS: Altogether 26 pseudocysts or abscesses were treated in 25 (6 female) patients. One endoscopist performed the procedures. Non-infected pseudocysts were present in 15 patients and 10 patients had infected fluid collections. The cyst size ranged between 28 cm × 13 cm and 5 cm × 5 cm. The EUS drainage was successful in 94% of the pseudocysts and in 80% of the abscesses (P = 0.04). The complication rate in pseudocysts was 6% and in abscesses was 30% (P = 0.02). Recurrence of a pseudocyst occurred in one patient (4%) after 6 mo; the patient was successfully retreated. CONCLUSION: EUS-guided drainage of pseudocysts is associated with a higher success rate and a lower complication rate compared with abscess drainage. | Riadh Sadik Evangelos Kalaitzakis Anders Thune Jan Hansen Claes Jnson | 2011 | World Journal of Gastroenterology2011，17，4： | 12 |
| 4 | Synergistic effect of multiple predisposing risk factors on the development of bezoars显示文摘AIM:To describe the clinical characteristics of patients with gastric or intestinal bezoars recently treated in our hospital.METHODS:In this study,a retrospective chart review of consecutive patients with gastrointestinal bezoars,who were treated at the Samsun Education and Research Hospital between January 2006 and March 2011,was conducted.Data on demographic characteristics,clinical presentation,history of risk factors,diagnostic procedures,localization of bezoars,treatment interventions,and postoperative morbidity and mortality rates were collected and evaluated.RESULTS:Forty-two patients [26 (61.9%) males and 16 (31.1%) females] with a mean±SD (range) age of 55.8±10.5 (37-74) years were enrolled in this study.Thirty-six patients (85.7%) had one or more predisposing risk factors for gastrointestinal bezoars.The most common predisposing risk factor was a history of previous gastric surgery which was identified in 18 patients (42.8%).Twenty three patients (54.8%) had multiple predisposing risk factors.Phytobezoars were identified in all patients except one who had a trichobezoar in the stomach.Non-operative endoscopic fragmentation was performed either initially or after unsuccessful medical treatment in 14 patients with gastric bezoars and was completely successful in 10 patients (71.5%).Surgery was the most frequent treatment method in our study,which was required in 28 patients (66.7%).Intestinal obstruction secondary to bezoars was the most common complication (n=18,42.8%) in our study.CONCLUSION:The presence of multiple predisposing factors may create a synergistic effect in the development of bezoars. | Metin Kement Nuraydin Ozlem Elif Colak Sadik Kesmer Cem Gezen Selahattin Vural | 2012 | World Journal of Gastroenterology2012，18，9： | 11 |
| 5 | Intervention to increase physical activity in irritable bowel syndrome shows long-term positive effects显示文摘AIM: To assess the long-term effects of physical activity on irritable bowel syndrome(IBS) symptoms and on quality of life, fatigue, depression and anxiety.METHODS: Seventy-six patients from a previous randomized controlled interventional study on increased physical activity in IBS were asked to participate in this long-term follow-up study. The included patients attended one visit in which they filled out questionnaires and they underwent a submaximal cycle ergometer test. The primary end point was the change in the IBS Severity Scoring System(IBS-SSS) at baseline, i.e., before the intervention and at follow-up. The secondary endpoints were changes in quality of life, fatigue, depression and anxiety.RESULTS: A total of 39 [32 women, median age 45(28-61) years] patients were included in this followup. Median follow-up time was 5.2(range: 3.8-6.2) years. The IBS symptoms were improved compared with baseline [IBS-SSS: 276(169-360) vs 218(82-328), P = 0.001]. This was also true for the majority of the dimensions of psychological symptoms such as disease specific quality of life, fatigue, depression and anxiety. The reported time of physical activity during the week before the visit had increased from 3.2(0.0-10.0) h at baseline to 5.2(0.0-15.0) h at follow-up, P = 0.019. The most common activities reported were walking, aerobics and cycling. There was no significant difference in the oxygen uptake 31.8(19.7-45.8) m L per min per kg at baseline vs 34.6(19.0-54.6) m L/min per kg at follow-up.CONCLUSION: An intervention to increase physical activity has positive long-term effects on IBS symptoms and psychological symptoms. | Elisabet Johannesson Gisela Ringstrom Hasse Abrahamsson Riadh Sadik | 2015 | World Journal of Gastroenterology2015，21，2： | 6 |
| 6 | Symptomatic subserosal gastric lipoma successfully treated with enucleation显示文摘Gastric lipomas are rare tumors, accounting for 2%-3% of all benign gastric tumors. They are of submucosal or extremely rare subserosal origin. Although most gastric lipomas are usually detected incidentally, they can cause abdominal pain, dyspeptic disorders, obstruction, invagination, and hemorrhages. Subserosal gastric lipomas are rarely symptomatic. There is no report on treatment of subserosal gastric lipomas in the English literature. We present a case of a 50-year-old male with symptomatic subserosal gastric lipoma which was successfully managed with removal, enucleation of lipoma, explorative gastrotomy and edge resection for histology check of gastric wall. The incidence of gastric lipoma, advanced diagnostic possibilities and their role in treatment modalities are discussed. | Avdyl Selmon Krasniqi Faton Tatil Hoxha Besnik Xhafer Bicaj Shemsedin Isuf Hashani Shpresa Mehmet Hasimja Sadik Mal Kelmendi Lumturije Hasan Gashi-Luci | 2008 | World Journal of Gastroenterology2008，14，38： | 4 |
| 7 | 糖尿病视网膜病变患者高密度脂蛋白-3和总抗氧化能力以及NO_x水平分析(英文)显示文摘目的:比较糖尿病视网膜病变组与对照组数据,以研究高密度脂蛋白-3(HDL_3)、NO_x和总抗氧化状态之间的关系。方法:前瞻性病例对照研究。106例受试者分为3组,84例2型糖尿病有或无视网膜病变患者,对照组为22例正常人。患者均行血清高密度脂蛋白-3的浓度检测和血清NO_x水平测定。用铁还原法(FRAP)测量血浆总抗氧化能力。结果:糖尿病患者(DM)空腹血糖、糖化血红蛋白、甘油三酯显著高于对照组。正常人中HDL_3水平为14.4(12.0)mg/dL,糖尿病视网膜病变患者为18.1(12.6)mg/dL,糖尿病无视网膜病变患者为14.0(12.5)mg/dL,组间差异无统计学意义(P=0.262)。糖尿病患者FRAP水平低于对照组(P=0.003),但糖尿病视网膜病变组与非糖尿病视网膜病变组之间其差异无统计学意义。结论:研究发现:2型糖尿病视网膜病变患者、糖尿病无视网膜病变患者以及对照组间HDL和HDL_3水平无明显不同。HDL_3可能无法预测糖尿病视网膜病变患者的患病风险。糖尿病患者中血清NO_x水平较高,FRAP水平较低。 | Ustundag Yasemin Akdogan Müberra Demirci Hakan Günay Leyla Huysal Kagan Cevik Sadik Gorkem Barazi Ayse | 2017 | 国际眼科杂志2017，17，12： | 3 |
| 8 | Comparative investigation of the free radical scavenging potential and anticancer property of Diospyros blancoi(Ebenaceae)显示文摘Objective: To investigate the comparative effects of Diospyros blancoi(Ebenaceae)leaves(DBL), root bark(DBRB) and stem bark(DBSB) on free radicals and cancer.Methods: The polyphenol contents, antioxidant and free radical scavenging properties were determined using standard spectrophotometric methods. Cytotoxicity and anticancer activities were performed on brine shrimp nauplii and Ehrlich ascite carcinoma cells, respectively.Results: Among the extracts, DBSB showed the highest total antioxidant capacity and reducing capacity on ferrous ion. Based on 1,1-diphenyl-2-picrylhydrazyl and hydroxyl radical scavenging activities, DBSB showed(95.760 ± 0.343)% and(67.460 ± 2.641)%scavenging with IC50of(3.10 ± 0.17) and(50.00 ± 3.11) mg/m L, respectively. The IC50 values of standard butylated hydroxytoluene and catechin(CA) for 1,1-diphenyl-2-picrylhydrazyl and hydroxyl radicals were(8.50 ± 0.25) and(75.00 ± 0.14) mg/m L,respectively suggesting that DBSB had a significant(P < 0.05) radical scavenging activity than standards. In lipid peroxidation inhibition assay, the inhibitory activity of the extracts and the standard was in the following order: DBSB > DBRB > CA > DBL.Also, the phenolic [(139.91 ± 3.924) mg gallic acid equivalent/g] and flavonoid contents[(412.00 ± 16.70) mg catechin equivalent/g)] of DBSB were higher than that of other extracts. In addition, the DBSB showed the moderate cytotoxic and anticancer properties.Conclusions: Our results indicate that Diospyros blancoi stem bark had the significant highest antioxidant and free radical scavenging properties as well as moderate anticancer activity.Hence, we assume that the anticancer activity of this plant can be, at least in part, attributed to its content in phenolic compounds as well as its significant free radical scavenging properties. | Muhammad Ali Khan Mahbubur Rahman Nazmul Sardar Saiful Islam Arman Badrul Islam Jahangir Alam Khandakar Mamunur Rashid Golam Sadik AHM Khurshid Alam | 2016 | Asian Pacific Journal of Tropical Biomedicine2016，6，5： | 3 |
| 9 | Attributes of cancer patients admitted to the emergency department in one year显示文摘BACKGROUND: Cancer patients frequently visit the emergency department(ED) with various symptoms of cancer. The purpose of this study was to determine the clinical characteristics and 1-year survival rate of cancer patients in the ED of a university hospital.METHODS: We conducted a retrospective review of 408 cancer patients who visited the ED between January 2011 and December 2011. Patient information on demographics, chief complaints, fi ndings, and survival was gathered from the hospital registry and corresponding health administration.RESULTS: The study included 240(58.8%) males and 168(41.2%) females with a median age of 57.9 years(range 19–87). Regarding cancer staging, 266 patients(65.3%) had metastatic disease and 142(34.7%) had local and loco-regional disease. The hospitalization rate was 59.6%. The most common symptoms were shortness of breath(23.2%), pain(17.8%), fever(14.2%), and nausea/vomiting(14.4%). The most common cancer sites were the lung(32.5%), gastrointestinal system(25.4%), and breast(9.3%). The initial evaluation determined progressive disease(42.4%), chemotherapy effects(20.7%), infections(17.2%), radiotherapy effects(4.7%), extravasation(1.8%), anemia(1.4%), and unknown(11.3%). During follow up, 191(46.8%) patients died after admission to the ED. The 1-year overall survival of all patients was 7.3 months.CONCLUSIONS: Symptom management in cancer patients is a complex multifaceted concern for the emergency physician. Because of the increasing prevalence of cancer patients, emergency physicians should develop consensus algorithms in collaboration with the relevant disciplines to manage the commonly encountered problems. | Muallaoglu Sadik Karagün Ozlem Mertsoylu Huseyin Besen AliAyberk Sezer Ahmet Ozyilkan Ozgur | 2014 | World Journal of Emergency Medicine2014，5，2： | 3 |
| 10 | A Study on Cyclone Aila Recovery in Koyra, Bangladesh:Evaluating the Inclusiveness of Recovery with Respect to Predisaster Vulnerability Reduction显示文摘The need to consider disaster risk reduction at the time of recovery is well-recognized. Viable disaster risk reduction measures should resolve the root causes of predisaster vulnerabilities. Accordingly, we investigated the recovery from the impact of Cyclone Aila in Koyra Upazila, Bangladesh, which was severely damaged by this2009 cyclone. Our research focused on understanding preAila vulnerabilities to cyclone impact and examined the degree of inclusion of vulnerability reduction measures within the recovery process. A composite methodology that included an institutional survey, key informant interviews,collection of the judgment of experts, focus group discussions, and a score-based quantification technique was adopted. Through a process of understanding pre-Aila vulnerabilities, recognition of the root causes of these inherent weaknesses, and identification of appropriate measures for pre-Aila vulnerability reduction, a set of 23 indicators were selected to represent the most desirable vulnerability reduction measures to implement duringrecovery. A score-based technique was applied to measure the degree of inclusion of vulnerability reduction within the recovery with respect to the indicators. The scoring result shows that the degree of inclusion of vulnerability reduction within the recovery was poor. The result specifies that among the 23 indicators of potential vulnerability reduction measures, 10 are completely missing and the rest are only partially included. The overall findings imply that the Koyra community continues to live with a vulnerability similar to that of the pre-Aila period. | Md.Shibly Sadik Hajime Nakagawa Rezaur Rahman Rajib Shaw Kenji Kawaike Kumiko Fujita | 2018 | International Journal of Disaster Risk Science2018，9，1： | 2 |

| 14 | Mechanical and antibacterial properties of tannic acid-encapsulated carboxymethyl chitosan/polyvinyl alcohol hydrogels显示文摘The objective of this study was to develop an effective,potential wound dressing,which was constructed with a composite hydrogel of poly(vinyl alcohol)(PVA),carboxymethyl chitosan(CMC)and tannic acid(TA)by cryogenic treatment and freeze-drying method.The as-prepared TA-crosslinked PVA/CMC hydrogels exhibited interconnected pore structure with the mean pore size of roughly 3.7��m.We found that the compressive strength and stiffness of composite hydrogel increased when the TA component was introduced.However,the PVA/CMC-TA hydrogel possessed obviously lower swell property than that of the TA-free PVA/CMC hydrogel.We also found that the TA addition significantly improved the antibacterial capacity of the as-prepared hydrogel.Moreover,the inhibition zone test showed that the antibacterial activity of PVA/CMC-TA against S.aureus bacteria was greater than that against E.coli.The biological results indicated that the PVA/CMC-TA hydrogel exhibited good cytocompatibility to natural human dermal fibroblasts.In summary,our PVA/CMC-TA composite hydrogel exhibited promising mechanical and antibacterial properties,which showed great potential application as wound healing materials. | Xiaofan Feng Xiuling Hou Congjing Cui Shibin Sun Sahiya Sadik Shaohua Wu Fang Zhou | 2021 | Engineered Regeneration2021，2，1： | 2 |
