| 1 | Endoscopic mucosal resection and endoscopic submucosal dissection in the treatment of sporadic nonampullary duodenal adenomatous polyps显示文摘Although uncommon, sporadic nonampullary duodenal adenomas have a growing detection due to the widespread of endoscopy. Endoscopic therapy is being increasingly used for these lesions, since surgery, considered the standard treatment, carries significant morbidity and mortality. However, the knowledge about its risks and benefits is limited, which contributes to the current absence of standardized recommendations. This review aims to discuss the efficacy and safety of endoscopic mucosal resection(EMR) and endoscopic submucosal dissection(ESD) in the treatment of these lesions. A literature review was performed, using the Pubmed database with the query: '(duodenum or duodenal)(endoscopy or endoscopic) adenoma resection', in the human species and in English. Of the 189 retrieved articles, and after reading their abstracts, 19 were selected due to their scientific interest. The analysis of their references, led to the inclusion of 23 more articles for their relevance in this subject. The increased use of EMR in the duodenum has shown good results with complete resection rates exceeding 80% and low complication risk(delayed bleeding in less than 12% of the procedures). Although rarely used in the duodenum, ESD achieves close to 100% complete resection rates, but is associated with perforation and bleeding risk in up to one third of the cases. Even though literature is insufficient to draw definitive conclusions, studies suggest that EMR and ESD are valid options for the treatment of nonampullary adenomas. Thus, strategies to improve these techniques, and consequently increase the effectiveness and safety of the resection of these lesions, should be developed. | Joana Marques Francisco Baldaque-Silva Pedro Pereira Urban Arnelo Naohisa Yahagi Guilherme Macedo | 2015 | World Journal of Gastrointestinal Endoscopy2015，7，7： | 13 |
| 2 | Phase Ⅰ of cardiac rehabilitation:A new challenge for evidence based physiotherapy显示文摘Cardiac rehabilitation protocols applied during the inhospital phase(phaseⅠ)are subjective and their results are contested when evaluated considering what should be the three basic principles of exercise prescription:specificity,overload and reversibility.In this review,we focus on the problems associated with the models of exercise prescription applied at this early stage in-hospital and adopted today,especially the lack of clinical studies demonstrating its effectiveness.Moreover,we present the concept of'periodization'as a useful tool in the search for better results. | Rafael Michel de Macedo JoséRocha Faria-Neto Costantino Ortiz Costantini Dayane Casali Andrea Pires Muller Costantino Roberto Costantini Katherine Athayde Teixeira de Carvalho Luiz César Guarita-Souza | 2011 | World Journal of Cardiology2011，3，7： | 11 |
| 3 | Reliability in endoscopic diagnosis of portal hypertensive gastropathy显示文摘AIM: To analyze reliability among endoscopists in diagnosing portal hypertensive gastropathy (PHG) and to determine which criteria from the most utilized classifications are the most suitable. METHODS: From January to July 2009, in an academic quaternary referral center at Santa Casa of S o Paulo Endoscopy Service, Brazil, we performed this singlecenter prospective study. In this period, we included 100 patients, including 50 sequential patients who had portal hypertension of various etiologies; who were previously diagnosed based on clinical, laboratory and imaging exams; and who presented with esophageal varices. In addition, our study included 50 sequentialpatients who had dyspeptic symptoms and were referred for upper digestive endoscopy without portal hypertension. All subjects underwent upper digestive endoscopy, and the images of the exam were digitally recorded. Five endoscopists with more than 15 years of experience answered an electronic questionnaire, which included endoscopic criteria from the 3 most commonly used Portal Hypertensive Gastropathy classifications (McCormack, NIEC and Baveno) and the presence of elevated or flat antral erosive gastritis. All five endosco- pists were blinded to the patients' clinical information, and all images of varices were deliberately excluded for the analysis. RESULTS: The three most common etiologies of portal hypertension were schistosomiasis (36%), alcoholic cirrhosis (20%) and viral cirrhosis (14%). Of the 50 patients with portal hypertension, 84% were Child A, 12% were Child B, 4% were Child C, 64% exhibited previous variceal bleeding and 66% were previously endoscopic treated. The endoscopic parameters, presence or absence of mosaic-like pattern, red point lesions and cherry-red spots were associated with high inter-observer reliability and high specificity for diagnosing Portal Hypertensive Gastropathy. Sensitivity, specificity and reliability for the diagnosis of PHG (%) were as follows: mosaic-like pattern (100; 92.21; High); fine pink speckling (56; 76.62; Unsatisfactory); superficial reddening (69.57; 66.23; Unsatisfactory); red-point lesions (47.83; 90.91; High); cherry-red spots (39.13; 96.10; High); isolated red marks (43.48; 88.31; High); and confluent red marks (21.74; 100; Unsatisfactory). Antral elevated erosive gastritis exhibited high reliability and high specificity with respect to the presence of portal hypertension (92%) and the diagnosis of portal hypertensive gastropathy (88.31%). CONCLUSION: The most suitable endoscopic criteria for the diagnosis of PHG were mosaic-like pattern, redpoint lesions and cherry-red spots with no subdivisions,which were associated with a high rate of inter-observer reliability. | George Fred Soares de Macedo Fabio Gon alves Ferreira Maurício Alves Ribeiro Luiz Arnaldo Szutan Mauricio Saab Assef Lucio Giovanni Battista Rossini | 2013 | World Journal of Gastrointestinal Endoscopy2013，5，7： | 9 |
| 4 | Autoimmune hepatitis and anti-tumor necrosis factor alpha therapy:A single center report of 8 cases显示文摘This article describes cases of anti-tumor necrosis factor(TNF)-α-induced autoimmune hepatitis and evaluates the outcome of these patients in relation to their immunosuppressive strategy. A retrospective analysis of medical records was performed in our center, in order to detect cases of autoimmune hepatitis(AIH) associated with anti-TNF biologic agents. We describe and analyze eight cases of AIH following anti-TNF therapy, 7 with infliximab and 1 with adalimumab. A distinction should be made between induction of autoimmunity and clinically evident autoimmune disease. Liver biopsy is useful in detecting the role of the TNF-α antagonist in the development of AIH. The lack of relapse after discontinuing immunosuppressive therapy favors, as in this case series, an immune-mediated drug reaction as most patients with AIH have a relapse after treatment is suspended. Although AIH related to anti-TNF therapy is rare, a baseline immunological panel along with liver function tests should be performed in all patients with autoimmune disease before starting biologics. | Susana Rodrigues Susana Lopes Fernando Magro Hélder Cardoso Ana Maria Horta e Vale Margarida Marques Eva Mariz Miguel Bernardes Joanne Lopes Fátima Carneiro Guilherme Macedo | 2015 | World Journal of Gastroenterology2015，21，24： | 9 |

| 9 | Lymphocyte subsets predictive value and possible involvement of human papilloma virus infection on breast cancer molecular subtypes显示文摘AIM To detect human papilloma virus(HPV) presence and to characterize cellular immune response in breast cancer patients. METHODS A total of 74 women were included, of which 48 samples were from patients diagnosed with breast cancer and 26 patients with benign pathology of the breast. Molecular subtype classification was performed based on the immunohistochemical reports of the tumor piece. HPV genome detection and genotyping from fresh breast biopsies was performed using the INNO-LIPA HPV Genotyping Extra test(Innogenetics, Ghent, Belgium). CD3+, CD4+, CD8+ and natural killer(NK)+ cells levels from peripheral blood samples from patients with breast cancer and benign pathology were measured by flow cytometry. RESULTS Luminal A was the most frequent breast cancer molecular subtype(33.33%). HPV was detected in 25% of the breast cancer patients, and genotype 18 was the most frequent in the studied population. The mean of CD3+, CD4+ and CD8+ subpopulations were decreased in patients with breast cancer, in relation to those with benign pathology, with a statistically significant difference in CD8+ values(P = 0.048). The mean of NK+ cells was increased in the benign pathology group. The average level of CD3+, CD4+, CD8+ and NK+ cells decreased as the disease progressed. HER2+ and Luminal B HER2+ tumors had the lowest counts of cell subsets. HPV breast cancer patients had elevated counts of cellular subsets. CONCLUSION Determining level changes in cellular subsets in breast cancer patients is a useful tool to evaluate treatment response. | Andreína Fernandes Adriana Pesci-Feltri Isabel García-Fleury Marco López Vincent Guida Marisol De Macedo María Correnti | 2018 | World Journal of Clinical Oncology2018，9，7： | 5 |
| 10 | Pancreatic intraepithelial neoplasia arising from an ectopic pancreas in the small bowel显示文摘BACKGROUND: Ectopic pancreatic tissue is relatively uncommon, and is characterized as pancreatic tissue with no contact with the normal pancreas, and with its own ductal system and blood supply. It is usually asymptomatic, and can be incidentally diagnosed by conventional imaging studies.METHOD: A 69-year-old woman with a prior history of bilateral breast carcinoma presented with ectopic pancreatic intraepithelial neoplasia (PanI N) that was identified incidentally in the small bowel during an oncological resection of a synchronous primary pancreatic adenocarcinoma, and renal cell carcinoma.RESULTS: The patient underwent subtotal pancreatectomy with splenectomy, regional lymphadenectomy, radical left nephrectomy, and small bowel resection with primary anastomosis of ectopic Pan IN-2. She had an uneventful hospitalization and was discharged home on postoperative day 7.CONCLUSIONS: The occurrence of ectopic PanI N is extremely unusual with only few cases previously reported in the literature. The need for negative margins after surgical resection of ectopic PanI N lesions remains controversial. | Francisco Igor Macedo Deepa Taggarshe Tafadzwa Makarawo Barry Herschman Michael J Jacobs | 2014 | Hepatobiliary & Pancreatic Diseases International2014，13，6： | 4 |
| 11 | Circulating leptin and its muscle gene expression in Nellore cattle with divergent feed efficiency显示文摘Background: Leptin has a strong relation to important traits in animal production, such as carcass composition,feed intake, and reproduction. It is mainly produced by adipose cells and acts predominantly in the hypothalamus.In this study, circulating leptin and its gene expression in muscle were evaluated in two groups of young Nellore bulls with divergent feed efficiency. Individual dry matter intake(DMI) and average daily gain(ADG) of 98 Nellore bulls were evaluated in feedlot for 70 d to determinate the residual feed intake(RFI) and select 20 animals for the high feed efficient(LRFI) and 20 for the low feed efficient(HRFI) groups. Blood samples were collected on d 56 and at slaughter(80 d) to determine circulating plasma leptin. Samples of Longissimus dorsi were taken at slaughter for leptin gene expression levels.Results: DMI and RFI were different between groups and LRFI animals showed less back fat and rump fat thickness,as well as less pelvic and kidney fat weight. Circulating leptin increased over time in all animals. Plasma leptin was greater in LRFI on 56 d and at slaughter(P = 0.0049). Gene expression of leptin were greater in LRFI animals(P = 0.0022) in accordance with the plasma levels. The animals of the LRFI group were leaner, ate less, and had more circulating leptin and its gene expression.Conclusion: These findings demonstrated that leptin plays its physiological role in young Nellore bulls, probably controlling food intake because feed efficient animals have more leptin and lower residual feed intake. | Lúcio Flávio Macedo Mota Cristina Moreira Bonafé Pamela Almeida Alexandre Miguel Henrique Santana Francisco JoséNovais Erika Toriyama Aldrin Vieira Pires Saulo da Luz Silva Paulo Roberto Leme JoséBento Sterman Ferraz Heidge Fukumasu | 2018 | Journal of Animal Science and Biotechnology2018，9，1： | 3 |

| 13 | Femtosecond laser-assisted deep anterior lamellar keratoplasty in phototherapeutic keratectomy versus the big-bubble technique in keratoconus显示文摘AIM:To compare the functional and anatomic results of femtosecond laser(FSL)-assisted deep anterior lamellar keratoplasty(DALK) associated with phototherapeutic keratectomy(PTK) and FSL-assisted DALK performed using the big-bubble technique in keratoconus.METHODS:During the first phase of the study,an electron microscopy histopathology pilot study was conducted that included four unsuitable donor corneas divided into two groups:in FSL group,FSL lamellar cuts were performed on two corneas and in FSL+PTK group,PTK was performed at the stromal beds of two corneas after FSL lamellar cuts were made.During the second phase of the study,a randomized clinical trial was conducted that included two treatment groups of patients with keratoconus:group 1(n=14 eyes) underwent FSL-assisted DALK associated with PTK and group 2(n=12 eyes) underwent FSL-assisted DALK associated with the bigbubble technique.The main outcome measures were the postoperative visual acuity(VA) and optical coherence tomography(OCT) measurements,confocal microscopic findings,and contrast sensitivity.RESULTS:In the pilot study,histopathology showed a more regular stromal bed in the FSL+PTK group.In the clinical trial,group 1 had significantly worse best spectaclecorrected VA and contrast sensitivity(P<0.05 for both comparisons).The residual stromal bed measured by OCT was significantly(P<0.05) thicker in group 1.Confocal microscopy detected opacities only at the donor-receptor interface in group 1.CONCLUSION:Patients with keratoconus treated with FSL-assisted DALK performed using the big-bubble technique fare better than treated with FSL-assisted DALK associated with PTK. | Jarbas Pereira de Macedo Lauro Augusto de Oliveira Flavio Hirai Luciene Barbosa de Sousa | 2018 | International Journal of Ophthalmology(English edition)2018，11，5： | 2 |
| 14 | Management of autoimmune hepatitis:Focus on pharmacologic treatments beyond corticosteroids显示文摘In autoimmune hepatitis, patients who are intolerant or with toxicity experience, non-responders, relapsers or refractory are challenging. Non-standard drugs are being tried to preemptively avoid corticosteroid-related side effects. Prognosis and quality of life of life rely on treatment optimization. Recently, emergence of powerful immunosuppressive agents, mainly from liver transplantation, challenged the supremacy of the corticosteroid regime and promise greater immunosuppression than conventional medications, offer site-specific actions and satisfactory patient tolerance. Successes in experimental models of related diseases have primed these molecular interventions. We performed a literature review on alternative treatments. Azatioprine intolerance is the principal indication for mycophenolate use butit can be used as a front-line therapy. Cyclosporine A and tacrolimus have been tested for non-responders or relapsers. Rituximab may be used as salvage therapy. Anti-tumor necrosis factor-alpha agents may be used for incomplete responses or non-responders. Methotrexate is possibly an alternative for induction of remission and maintenance in refractory patients. Cyclophosphamide has been included in the induction regimen with corticosteroids. Ursodeoxycholic acid action is mainly immunomodulatory. Non-standard treatments are coming slowly to the attention, but its use should be cautious performed by experienced centers. | Marta Casal Moura Rodrigo Liberal Hélder Cardoso Ana Maria Horta e Vale Guilherme Macedo | 2014 | World Journal of Hepatology2014，6，6： | 2 |
