| 1 | Rubber band ligation of hemorrhoids: A guide for complications显示文摘Rubber band ligation is one of the most important, costeffective and commonly used treatments for internal hemorrhoids. Different technical approaches were developed mainly to improve efficacy and safety. The technique can be employed using an endoscope with forward-view or retroflexion or without an endoscope, using a suction elastic band ligator or a forceps ligator. Single or multiple ligations can be performed in a single session. Local anaesthetic after ligation can also be used to reduce the post-procedure pain. Mild bleeding, pain, vasovagal symptoms, slippage of bands, priapism, difficulty in urination, anal fissure, and chronic longitudinal ulcers are normally considered minor complications, more frequently encountered. Massive bleeding, thrombosed hemorrhoids, severe pain, urinary retention needing catheterization, pelvic sepsis and death are uncommon major complications. Mild pain after rubber band ligation is the most common complication with a high frequency in some studies. Secondary bleeding normally occurs 10 to 14 d after banding and patients taking anti-platelet and/or anti-coagulant medication have a higher risk, with some reports of massive life-threatening haemorrhage. Several infectious complications have also been reported including pelvic sepsis, Fournier's gangrene, liver abscesses, tetanus and bacterial endocarditis. To date, seven deaths due to these infectious complications were described. Early recognition and immediate treatment of complications are fundamental for a favourable prognosis. | Andreia Albuquerque | 2016 | World Journal of Gastrointestinal Surgery2016,8,9: | 22 |
| 2 | Does autologous blood transfusion during liver transplantation for hepatocellular carcinoma increase risk of recurrence?显示文摘AIM: To analyze outcomes in patients who underwent liver transplantation(LT) for hepatocellular carcinoma(HCC) and received autologous intraoperative blood salvage(IBS). METHODS: Consecutive HCC patients who underwent LT were studied retrospectively and analyzed according to the use of IBS or not. Demographic and surgical data were collected from a departmental prospective maintained database. Statistical analyses were performed using the Fisher's exact test and the Wilcoxon rank sum test to examine covariate differences between patients who underwent IBS and those who did not. Univariate and multivariate Cox regression models were developed to evaluate recurrence and death,and survival probabilities were estimated using the Kaplan-Meier method and compared by the log-rank test.RESULTS: Between 2002 and 2012,158 consecutive patients who underwent LT in the same medical center and by the same surgical team were identified. Among these patients,122(77.2%) were in the IBS group and 36(22.8%) in the non-IBS group. The overall survival(OS) and recurrence free survival(RFS) at 5 years were 59.7% and 83.3%,respectively. No differences in OS(P=0.51) or RFS(P=0.953) were detected between the IBS and non-IBS groups. On multivariate analysis for OS,degree of tumor differentiation remained as the only independent predictor. Regarding patients who received IBS,no differences were detected in OS or RFS(P=0.055 and P=0.512,respectively) according to the volume infused,even when outcomes at 90 d or longer were analyzed separately(P=0.518 for both outcomes).CONCLUSION: No differences in RFS or OS were detected according to IBS use. Trials addressing this question are justified and should be designed to detect small differences in long-term outcomes. | Raphael LC Araujo Carlos Andrés Pantanali Luciana Haddad Joel Avancini Rocha Filho Luiz Augusto Carneiro D’Albuquerque Wellington Andraus | 2016 | World Journal of Gastrointestinal Surgery2016,8,2: | 14 |

| 4 | Great progress in study on aerosol and its impact on the global environment显示文摘The transport from atmosphere is a more important pathway than that from rivers for certain elements and compounds in the remote ocean. The desert and those arid/semi-arid areas in the northwest of China and the Loess Plateau are the sources of those aerosols over the Pacific. Atmospheric iron is the limiting factor of the productivity in certain ocean regions. The dust storms must now be seen as repeated sources of pollution elements as well as soil elements to the East China Sea and, farther out, to the North Pacific Ocean and even to the USA. The long-range transport of aerosols, especially the dust storm, from China and the positive feedbacks of iron coupled with sulfur in atmosphere might be one of the important mechanisms that would affect the primary productivity in the Pacific and/or the global climate change and deserve to be further studied. It can be seen clearly that the dust storms would affect not only the health of human beings and the local or regional climate, but also the global climate change that has been the focus of environmental study internationally. | ZHUANG Guoshun, HUANG Ronghui, WANG Mingxing, Q.

| 5 | Phase angle obtained by bioelectrical impedance analysis independently predicts mortality in patients with cirrhosis显示文摘AIM To evaluate the prognostic value of the phase angle(PA)obtained from bioelectrical impedance analysis(BIA) for mortality prediction in patients with cirrhosis. METHODS In total, 134 male cirrhotic patients prospectively completed clinical evaluations and nutritional assessment by BIA to obtain PAs during a 36-mo follow-up period. Mortality risk was analyzed by applying the PA cutoff point recently proposed as a malnutrition marker(PA ≤ 4.9°) in Kaplan-Meier curves and multivariate Cox regression models. RESULTS The patients were divided into two groups according to the PA cutoff value(PA > 4.9°, n = 73; PA ≤ 4.9°, n = 61). Weight, height, and body mass index were similar in both groups, but patients with PAs > 4.9° were younger and had higher mid-arm muscle circumference, albumin, and handgrip-strength values and lower severe ascites and encephalopathy incidences, interleukin(IL)-6/IL-10 ratios and C-reactive protein levels than did patients with PAs ≤ 4.9°(P ≤ 0.05). Forty-eight(35.80%) patients died due to cirrhosis, with a median of 18 mo(interquartile range, 3.3-25.6 mo) follow-up until death. Thirty-one(64.60%) of these patients were from the PA ≤ 4.9° group. PA ≤ 4.9° significantly and independently affected the mortality model adjusted for Model for End-Stage Liver Disease score and age(hazard ratio = 2.05, 95%CI: 1.11-3.77, P = 0.021). In addition, Kaplan-Meier curves showed that patients with PAs ≤ 4.9° were significantly more likely to die. CONCLUSION In male patients with cirrhosis, the PA ≤ 4.9° cutoff was associated independently with mortality and identified patients with worse metabolic, nutritional, and disease progression profiles. The PA may be a useful and reliable bedside tool to evaluate prognosis in cirrhosis. | Giliane Belarmino Maria Cristina Gonzalez Raquel S Torrinhas Priscila Sala Wellington Andraus Luiz Augusto Carneiro D'Albuquerque Rosa Maria R Pereira Valéria F Caparbo Graziela R Ravacci Lucas Damiani Steven B Heymsfield Dan L Waitzberg | 2017 | World Journal of Hepatology2017,9,7: | 11 |
| 6 | Role of mi RNAs and their potential to be useful as diagnostic and prognostic biomarkers in gastric cancer显示文摘Alterations in epigenetic control of gene expression play an important role in many diseases, including gastric cancer. Many studies have identified a large number of upregulated oncogenic mi RNAs and downregulated tumour-suppressor mi RNAs in this type of cancer. In this review, we provide an overview of the role of mi RNAs, pointing to their potential to be useful as diagnostic and/or prognostic biomarkers in gastric cancer. Moreover, we discuss the influence of polymorphisms and epigenetic modifications on mi RNA activity. | Kelly Cristina da Silva Oliveira Taíssa Maíra Thomaz Araújo Camila Inagaki Albuquerque Gabriela Alcantara Barata Carolina Oliveira Gigek Mariana Ferreira Leal Fernanda Wisnieski Fernando Augusto Rodrigues Mello Junior André Salim Khayat Paulo Pimentel de Assumpcao Rommel Mário Rodriguez Burbano Marília Cardoso Smith Danielle Queiroz Calcagno | 2016 | World Journal of Gastroenterology2016,22,35: | 11 |
| 7 | Pre-and postoperative systemic hemodynamic evaluation in patients subjected to esophagogastric devascularization plus splenectomy and distal splenorenal shunt:A comparative study in schistomomal portal hypertension显示文摘AIM: To investigate the systemic hemodynamic effects of two surgical procedures largely employed for treatment of schistosomal portal hypertension. METHODS: Thirty-six patients undergoing elective surgical treatment of portal hypertension due to hepatosplenic mansonic schistosomiasis were prospectively evaluated. All patients were subjected to preoperative pulmonary artery catheterization; 17 were submitted to esophagogastric devascularization and splenectomy (EGDS) and 19 to distal splenorenal shunt (DSRS). The systemic hemodynamic assessment was repeated 4 d after the surgical procedure. RESULTS: Preoperative evaluation revealed (mean ± SD) an increased cardiac index (4.78 ± 1.13 L/min per m2),associated with a reduction in systemic vascular resistance index (1457 ± 380.7 dynes.s/cm5.m2). The mean pulmonary artery pressure (18 ± 5.1 mmHg) as well as the right atrial pressure (7.9 ± 2.5 mmHg) were increased,while the pulmonary vascular resistance index (133 ± 62 dynes.s/cm5.m2) was decreased. Four days after EGDS,a significant reduction in cardiac index (3.80 ± 0.4 L/min per m2,P < 0.001) and increase in systemic vascular resistance index (1901.4 ± 330.2 dynes.s/cm5. m2,P < 0.001) toward normal levels were observed. There was also a significant reduction in pulmonary artery pressure (12.65 ± 4.7 mmHg,P < 0.001) and no significant changes in the pulmonary vascular resistance index (141.6 ± 102.9 dynes.s/cm5.m2). Four days after DSRS,a non-significant increase in cardiac index (5.2 ± 0.76 L/min per m2) and systemic vascular resistance index (1389 ± 311 dynes.s/cm5.m2) was observed. There was also a non-significant increase in pulmonary artery pressure (19.84 ± 5.2 mmHg),right cardiac work index (1.38 ± 0.4 kg.m/m2) and right ventricular systolic work index (16.3 ± 6.3 g.m/m2),without significant changes in the pulmonary vascular resistance index (139.7 ± 67.8 dynes.s/cm5.m2). CONCLUSION: The hyperdynamic circulatory state observed in mansonic schistosomiasis was corrected by EGDS,but was maintained in patients who underwent DSRS. Similarly,the elevated mean pulmonary artery pressure was corrected after EGDS and maintained after DSRS. EGDS seems to be the most physiologic surgery for patients with schistosomal portal hypertension. | Roberto de Cleva Paulo Herman Luis Augusto Carneiro D’albuquerque Vincenzo Pugliese Orlando Luis Santarem William Abro Saad | 2007 | World Journal of Gastroenterology2007,13,41: | 9 |
| 8 | Nodular lymphoid hyperplasia in the gastrointestinal tract in adult patients: A review显示文摘Nodular lymphoid hyperplasia of the gastrointestinal tract is characterized by the presence of multiple small nodules, normally between between 2 and 10 mm in diameter, distributed along the small intestine(more often), stomach, large intestine, or rectum. The patho-genesis is largely unknown. It can occur in all age groups, but primarily in children and can affect adults with or without immunodeficiency. Some patients have an associated disease, namely, common variable immu-nodeficiency, selective IgA deficiency, Giardia infection, or, more rarely, human immunodeficiency virus infec-tion, celiac disease, or Helicobacter pylori infection. Nodular lymphoid hyperplasia generally presents as an asymptomatic disease, but it may cause gastrointes-tinal symptoms like abdominal pain, chronic diarrhea, bleeding or intestinal obstruction. A diagnosis is made at endoscopy or contrast barium studies and should be confirmed by histology. Its histological characteristics include markedly hyperplasic, mitotically active germi-nal centers and well-defined lymphocyte mantles found in the lamina propria and/or in the superficial submu-cosa, distributed in a diffuse or focal form. Treatment is directed towards associated conditions because the disorder itself generally requires no intervention. Nodu-lar lymphoid hyperplasia is a risk factor for both intes-tinal and, very rarely, extraintestinal lymphoma. Someauthors recommend surveillance, however, the duration and intervals are undefined. | Andreia Albuquerque | 2014 | World Journal of Gastrointestinal Endoscopy2014,6,11: | 8 |
| 9 | 颈部动脉夹层分离及其与颈椎推拿疗法的联系:美国心脏协会/美国卒中协会对医疗专业人员的声明显示文摘目的:颈部动脉夹层分离(cervicalarterydissection,CD)是中青年人卒中的最常见病因。本指南旨在对CD诊治的现有证据水平以及其与颈椎推拿疗法(cervical manipulative therapy, CMT)的统计学联系进行回顾。某些类型的CMT是由医疗专业人员对颈椎施加猛烈或轻柔的推力。方法写作组成员由美国心脏协会卒中委员会的科学声明监督委员会以及美国心脏协会的手稿监督委员会任命。各成员负责与其专业领域相关的主题,回顾适当的文献并参考公开发表的临床和流行病学研究、发病率和死亡率报告、临床与公共卫生指南、权威声明、个人文件以及专家意见,对现有证据进行总结并指出目前的知识空白。结果CD患者可表现为单侧头痛、后颈部痛或主要由动脉-动脉栓塞导致的脑或视网膜缺血(短暂性缺血或卒中)、CD脑神经麻痹、眼交感神经麻痹或搏动性耳鸣。CD的诊断依赖于完整的病史、体格检查和针对性的辅助检查。尽管轻微创伤的作用存在争议,但机械压力可造成椎动脉和颈内动脉内膜损伤,进而导致CD。CD患者的残疾程度存在差异,一些患者预后良好,但有些患者则会出现严重神经系统后遗症。目前尚无循证指南可用来指导CD的最佳处理策略。抗血小板和抗凝治疗均被用于局部血栓和继发性栓塞的预防。病例对照研究和其他文献提示CD[尤其是椎动脉夹层分离(vertebral artery dissection, VAD)]与CMT之间存在流行病学联系,但尚不清楚这是由于对先前存在的CD认识不足还是CMT导致的创伤。超声、CT血管造影以及磁共振血管造影都有助于CD的诊断。神经影像学随访首选无创性检查措施,但我们认为任何单一的检查方法都不能作为金标准。结论 CD是中青年患者发生缺血性卒中的重要病因。CD最好发于颈椎上段,可累及颈内动脉或椎动脉。尽管目前的生物力学证据不足以证实CMT 可导致CD,但临床报道提示机械压力在相当一部分CD中起着一定的作用,而且大多数基于人群的对照研究在年轻患者中显示CMT与VAD卒中之间存在联系。尽管对于曾经接受过CMT的患者,CMT相关性CD的发生率尚不完全清楚并且很可能较低,但当有临床症状时,医生应考虑到CD的可能性,并且在进行颈椎推拿前告知患者CD与CMT之间的统计学联系。 | José Biller Ralph L.

| 11 | In vitro antibacterial effect of aqueous and ethanolic Moringa leaf extracts显示文摘Objective:To evaluate the antibacterial effect of aqueous and ethanolic moringa leaf extracts (Moringa oleifera) on the growth of gram-positive and negative bacteria.Methods:Paper disks were soaked with 100,200,300 and 400μL of extract at 20 g/180mL and 10 g/190 mL.All extracts were tested against Escherichia coli(ATCC25922),Staphylococcus aureus(ATCC25923),Vibrio parahaemolyticus,Enterococcus faecalis(ATCC29212),Pseudomonas aeruginosa(ATCC27853), Salmonella enteritidis(IH) and Aeromonas caviae.The susceptibility tests were performed using the modified disk diffusion method.Results:The strains E.coli,P.aeruginosa and S.enteritidis (IH) were resistant to all treatments.In general,disks with 400μL extract were the most efficient against S.aureus,V.parahaemolyticus,E.faecalis and A.caviae.Conclusions:The study indicates a promising potential for aqueous and ethanolic Moringa leaf extracts as alternative treatment of infections caused by the tested strains. | Jackson Rafael Oliveira Peixoto Giselle Cristina Silva Renata Albuquerque Costa Joseires Lira de Sousa Fontenelle Gustavo Hitzschky Fernandes Vieira Antonio Adauto Fonteles Filho Regine Helena Silva dos Fernandes Vieira | 2011 | Asian Pacific Journal of Tropical Medicine2011,4,3: | 7 |
| 12 | Short-term complementary and alternative medicine on quality of life in women with fibromyalgia显示文摘BACKGROUND:Fibromyalgia(FMS)is a syndrome characterized by chronic widespread musculoskeletal pain,whose etiology is not completely understood.Different therapeutic approaches have been used with inconsistent results.This observation does not invalidate the continued search for alternative treatments aimed at improving quality of life(Qo L)in FMS.OBJECTIVE:This study compared three classical traditional Chinese medicine(TCM)therapies:acupuncture(AC),electroacupuncture(EAC)and moxibustion(MX)in the management of pain and promotion of Qo L in FMS patients.DESIGN,SETTING,PARTICIPANTS AND INTERVENTIONS:A preliminary,group-assigned,comparative study enrolled 30 women,mean age(46.90±9.24)years(range 20–60 years),who met the 1990 American College of Rheumatology criteria for FMS diagnosis and a pain-pressure threshold(PPT)< 4 kg/cm^2.The study was conducted in a teaching tertiary-care medical institution from May 2010 through April 2012.AC,EAC and MX were delivered for 30 min,once a week,for 8 weeks,bilaterally at Neiguan(PC6),Hegu(LI4),Yanglingquan(GB34),Sanyinjiao(SP6)and Taichong(LR3)acupoints.MAIN OUTCOME MEASURES:Each week,immediately before treatment and after treatment,subjects were tested for PPTs,Wong-Baker Faces Pain Scale(WBFPS;for pain intensity)and Medical Outcomes Study 36-item Short Form Health Survey(SF-36:for Qo L).RESULTS:There was no signifi cant improvement in pain or reduction of tender points in any of the groups studied,at the end of the 8th session.Signifi cant improvement of Qo L was perceived in vitality(after AC treatment)and in mental health(after EAC and MX treatments).CONCLUSION:TCM therapies(AC,EAC and MX)promoted an improvement in the Qo L in two areas(vitality and mental health)in FMS women.Further large-scale clinical trials are required to confi rm this effect. | Paulo Araujo Dias Andre Brito Bastos Guimaraes Andrea de Oliveira Albuquerque Karoline Lucas de Oliveira Maria Luzete Costa Cavalcante Sergio Botelho Guimaraes | 2016 | Journal of Integrative Medicine2016,14,1: | 7 |
| 13 | hsa-miR-29c and hsa-miR-135b differential expression aspotential biomarker of gastric carcinogenesis显示文摘AIM: To investigate the expression profiles of hsa-mi R-29 c and hsa-mi R-135 b in gastric mucosal samples and their values as gastric carcinogenesis biomarkers. METHODS: The expression levels of hsa-mi R-29 c and hsa-mi R-135 b in normal gastric mucosa, non-atrophic chronic gastritis, intestinal metaplasia and intestinaltype gastric adenocarcinoma were analysed using quantitative real-time PCR. The difference between hsa-mi R-29 c and hsa-mi R-135 b expression profiles in the grouped samples was evaluated by ANOVA and Student's t-test tests. The results were adjusted for multiple testing by using Bonferroni's correction. P values ≤ 0.05 were considered statistically significant. To evaluate hsa-mi R-29 c and hsa-mi R-135 b expressions as potential biomarkers of gastric carcinogenesis, we performed a receiver operating characteristic curve analysis and the derived area under the curve, and a Categorical Principal Components Analysis. In silico identification of the genetic targets of hsa-mi R-29 c and hsa-mi R-135 b was performed using different prediction tools, in order to identify possible genes involved in gastric carcinogenesis.RESULTS: The expression levels of hsa-mi R-29 c were higher in normal gastric mucosal samples, and decreased progressively in non-atrophic chronic gastritis samples, intestinal metaplasia samples and intestinal-type gastric adenocarcinoma samples. The expression of hsa-mi R-29 c in the gastric lesions showed that non-atrophic gastritis have an intermediate profile to gastric normal mucosa and intestinal-type gastric adenocarcinoma, and that intestinal metaplasia samples presented an expression pattern similar to that in intestinal-type gastric adenocarcinoma. This micro RNA(mi RNA) has a good discriminatory accuracy between normal gastric samples and(1) intestinal-type gastric adenocarcinoma; and(2) intestinal metaplasia, and regulates the DMNT3 A oncogene. hsa-mi R-135 b is up-regulated in non-atrophic chronic gastritis and intestinal metaplasia samples and down-regulated in normal gastric mucosa and intestinal-type gastric adenocarcinoma samples. Non-atrophic chronic gastritis and intestinal metaplasia are significantly different from normal gastric mucosa samples. hsa-mi R-135 b expression presented a greater discriminatory accuracy between normal samples and gastric lesions. This mi RNA was associated with Helicobacter pylori presence in non-atrophic chronic gastritis samples and regulates the APC and KLF4 tumour suppressor genes.CONCLUSION: Our results provide evidence of epigenetic alterations in non-atrophic chronic gastritis and intestinal metaplasia and suggest that hsa-mi R-29 c and hsa-mi R-135 b are promising biomarkers of gastric carcinogenesis. | Amanda Ferreira Vidal Aline MP Cruz Leandro Magalhães Adenilson L Pereira Ana KM Anaissi Nélisson CF Alves Paulo JBS Albuquerque Rommel MR Burbano Samia Demachki Ândrea Ribeiro-dos-Santos | 2016 | World Journal of Gastroenterology2016,22,6: | 7 |
| 14 | Hepatic ischemic preconditioning increases portal vein flow in experimental liver ischemia reperfusion injury显示文摘BACKGROUND: Ischemic preconditioning(IPC) has been shown to decrease liver injury and to increase hepatic microvascular perfusion after liver ischemia reperfusion. This study aimed to evaluate the effects of IPC on hemodynamics of the portal venous system. METHODS: Thirty-two rats were randomized into two groups: IPC group and control group. The rats of the IPC group underwent IPC by 10 minutes of liver ischemia followed by 10 minutes of reperfusion before liver ischemia, and the rats of the control group were subjected to 60 minutes of partial liver ischemia. Non-ischemic lobes were resected immediately after reperfusion. The animals were studied at 4 hours and 12 hours after reperfusion. Mean arterial pressure, heart rate, portal vein flow and pressure were analyzed. Blood was collected for the determination of the levels of aspartate aminotransferase, alanine aminotransferase, calcium, lactate, pH, bicarbonate, and base excess. RESULTS: IPC increased the mean portal vein flow at 4 hours and 12 hours after reperfusion. IPC recovered 78% of the meanportal vein flow at 12 hours after reperfusion. IPC decreased the levels of aspartate aminotransferase, alanine aminotransferase and lactate, and increased the levels of ionized calcium, bicarbonate and base excess at 12 hours after reperfusion. CONCLUSIONS: This study demonstrated that IPC increases portal vein flow and enhances hepatoprotective effects in liver ischemia reperfusion. The better recovery of portal vein flow after IPC may be correlated with the lower levels of transaminases and with the better metabolic profile. | Estela RR Figueira Joel A Rocha-Filho Mauro Nakatani Marcelo FS Buto Eduardo R Tatebe Vitor O Andre Ivan Cecconello Luiz AC D'Albuquerque | 2014 | Hepatobiliary & Pancreatic Diseases International2014,13,1: | 6 |
| 15 | Current applications of transperineal ultrasound in gastroenterology显示文摘Transperineal ultrasound is an inexpensive,safe and painless technique that dynamically and non-invasively evaluates the anorectal area.It has multiple indications,mainly in urology,gynaecology,surgery and gastroenterology,with increased use in the last decade.It is performed with conventional probes,positioned directly above the anus,and may capture images of the anal canal,rectum,puborectalis muscle(posterior compartment),vagina,uterus,(central compartment),urethra and urinary bladder(anterior compartment).Evacuatory disorders and pelvic floor dysfunction,like rectoceles,enteroceles,rectoanal intussusception,pelvic floor dyssynergy can be diagnosed using this technique.It makes a dynamic evaluation of the interaction between pelvic viscera and pelvic floor musculature,with images obtained at rest,straining and sustained squeezing.This technique is an accurate examination for detecting,classifying and following of perianal inflammatory disease.It can also be used to sonographically guide drainage of deep pelvic abscesses,mainly in patients who cannot undergo conventional drainage.Transperineal ultrasound correctly evaluates sphincters in patients with fecal incontinence,postpartum and also following surgical repair of obstetric tears.There are also some studies referring to its role in anal stenosis,for the measurement of the anal cushions in haemorrhoids and in chronic anal pain. | Andreia Albuquerque Eduardo Pereira | 2016 | World Journal of Radiology2016,8,4: | 5 |
| 16 | Current aspects of renal dysfunction after liver transplantation显示文摘The development of chronic kidney disease(CKD)after liver transplantation(LT)exerts a severe effect on the survival of patients.The widespread adoption of the model for end-stage liver disease score strongly impacted CKD incidence after the procedure,as several patients are transplanted with previously deteriorated renal function.Due to its multifactorial nature,encompassing pre-transplantation conditions,perioperative events,and nephrotoxic immunosuppressor therapies,the accurate identification of patients under risk of renal disease,and the implementation of preventive approaches,are extremely important.Methods for the evaluation of renal function in this setting range from formulas that estimate the glomerular filtration rate,to non-invasive markers,although no option has yet proved efficient in early detection of kidney injury.Considering the nephrotoxicity of calcineurin inhibitors(CNI)as a factor of utmost importance after LT,early nephroprotective strategies are highly recommended.They are based mainly on delaying the application of CNI during the immediate postoperativeperiod,reducing their dosage,and associating them with other less nephrotoxic drugs,such as mycophenolate mofetil and everolimus.This review provides a critical assessment of the causes of renal dysfunction after LT,the methods of its evaluation,and the interventions aimed at preserving renal function early and belatedly after LT. | Mariana P Pacheco Luiz Augusto Carneiro-D'Albuquerque Daniel F Mazo | 2022 | World Journal of Hepatology2022,14,1: | 5 |
| 17 | Percutaneous radiofrequency ablation for early hepatocellular carcinoma: Risk factors for survival显示文摘AIM: To evaluate outcomes of radiofrequency ablation(RFA) therapy for early hepatocellular carcinoma(HCC) and identify survival- and recurrence-related factors. METHODS: Consecutive patients diagnosed with early HCC by computed tomography(CT) or magnetic resonance imaging(MRI)(single nodule of ≤ 5 cm, or multi-(up to 3) nodules of ≤ 3 cm each) and who underwent RFA treatment with curative intent between January 2010 and August 2011 at the Instituto do Cancer do Estado de S o Paulo, Brazil were enrolled in the study. RFA of the liver tumors(with 1.0 cm ablative margin) was carried out under CT-fluoro scan and ultrasonic image guidance of the percutaneous ablation probes. Procedure-related complications were recorded. At 1-mo post-RFA and 3-mo intervals thereafter, CT and MRI were performed to assess outcomes of complete response(absence of enhancing tissue at the tumor site) or incomplete response(enhancing tissue remaining at the tumor site). Overall survival and diseasefree survival rates were estimated by the Kaplan-Meier method and compared by the log rank test or simple Cox regression. The effect of risk factors on survival was assessed by the Cox proportional hazard model. RESULTS: A total of 38 RFA sessions were performed during the study period on 34 patients(age in years: mean, 63 and range, 49-84). The mean follow-up time was 22 mo(range, 1-33). The study population showed predominance of male sex(76%), less severe liver disease(Child-Pugh A, n = 26; Child-Pugh B, n = 8), and single tumor(65%). The maximum tumor diameters ranged from 10 to 50 mm(median, 26 mm). The initial(immediately post-procedure) rate of RFAinduced complete tumor necrosis was 90%. The probability of achieving complete response was significantly greater in patients with a single nodule(vs patients with multi-nodules, P = 0.04). Two patients experienced major complications, including acute pulmonary edema(resolved with intervention) and intestinal perforation(led to death). The 1- and 2-year overall survival rates were 82% and 71%, respectively. Sex, tumor size, initial response, and recurrence status influenced survival, but did not reach the threshold of statistical significance. Child-Pugh class and the model for end-stage liver disease score were identified as predictors of survival by simple Cox regression, but only Child-Pugh class showed a statistically significant association to survival in multiple Cox regression analysis(HR = 15; 95%CI: 3-76 mo; P = 0.001). The 1-and 2-year cumulative disease-free survival rates were 65% and 36%, respectively. CONCLUSION: RFA is an effective therapy for local tumor control of early HCC, and patients with preserved liver function are the best candidates. | Luciana Kikuchi Marcos Menezes Aline L Chagas Claudia M Tani Regiane SSM Alencar Marcio A Diniz Venncio AF Alves Luiz Augusto Carneiro D’Albuquerque Flair José Carrilho | 2014 | World Journal of Gastroenterology2014,20,6: | 5 |
| 18 | Biological processes and signal transduction pathwaysregulated by the protein methyltransferase SETD7 and theirsignificance in cancer显示文摘Protein methyltransferases have been shown to methylate histone and non-histone proteins,leading to regulation of several biological processes that control cell homeostasis.Over the past few years,the histone-lysine N-methyltransferase SETD7(SETD7;also known as SET7/9,KIAA1717,KMT7,SET7,SET9)has emerged as an important regulator of at least 30 non-histone proteins and a potential target for the treatment of several human diseases.This review discusses current knowledge of the structure and subcellular localization of SETD7,as well as its function as a histone and non-histone methyltransferase.This work also underlines the putative contribution of SETD7 to the regulation of gene expression,control of cell proliferation,differentiation and endoplasmic reticulum stress,which indicate that SETD7 is a candidate for novel targeted therapies with the aim of either stimulating or inhibiting its activity,depending on the cell signaling context. | Ines de Albuquerque Almeida Batista Luisa Alejandra Helguero | 2018 | Signal Transduction and Targeted Therapy2018,3,1: | 4 |
| 19 | Oral pharmacological treatment for patent ductus arteriosus in premature neonates with hemodynamic repercussions显示文摘Objective: To evaluate the efficacy of oral indomethacin, ibuprofen, and paracetamol in oral dosage form on patent ductus arteriosus(PDA) in premature neonates with significant clinical and hemodynamic repercussions(CHRs) and to determine the effect of these respective treatments on renal function.Methods: A retrospective study of cases of PDA in premature neonates in the Neonatal Intensive Care Unit was conducted. The treatments consisted of indomethacin[0.2 mg/(kg$d), 3-day cycle], ibuprofen [10 mg/(kg$d) followed by 5 mg/(kg$d), 3-day cycle], and paracetamol(15 mg/kg every 6 h, 5-day cycle). The drugs were administered as an oral solution. The following variables were considered: gestational age,newborn weight at birth, Apgar score, diuresis, serum creatinine and urea levels, and serum electrolyte levels(sodium and potassium).Results: Treatment with indomethacin presented efficacy of 87.5% in closure of the ductus with a mean outcome period of 3.5 d. In premature neonates with CHRs and contraindications for indomethacin, the initial treatment with either ibuprofen or paracetamol failed to close the ductus. However, when this treatment was followed by indomethacin, closure occurred in 66.7% of the neonates, with an outcome period of9.66 d. The initial treatment with one cycle of ibuprofen followed by one or two cycles of paracetamol failed to close the ductus.Conclusions: Oral indomethacin was effective for closure of the PDA in premature neonates with severe CHRs. Oral paracetamol or ibuprofen for PDA closure in premature neonates with severe CHRs and contraindications for indomethacin was ineffective.However, results in clinical improvements of neonates allowed the subsequent use of indomethacin and successful closure of the ductus. A significant reduction of diuresis occurred in neonates who were treated with indomethacin, either as a first-line treatment or after the failure of ibuprofen or paracetamol. | Clarissa de Albuquerque Botura Bruno Ambrósio da Rocha Thiely Balensiefer Franciele Queiroz Ames Ciomar Aparecida Bersani-Amado Roberto Kenji Nakamura Cuman | 2017 | Asian Pacific Journal of Tropical Medicine2017,10,11: | 4 |
