| 1 | Acute calculous cholecystitis: Review of current best practices显示文摘Acute calculous cholecystitis(ACC) is the most frequent complication of cholelithiasis and represents one-third of all surgical emergency hospital admissions, many aspects of the disease are still a matter of debate. Knowledge of the current evidence may allow the surgical team to develop practical bedside decision-making strategies, aiming at a less demanding procedure and lower frequency of complications. In this regard, recommendations on the diagnosis supported by specific criteria and severity scores are being implemented, to prioritize patients eligible for urgency surgery. Laparoscopic cholecystectomy is the best treatment for ACC and the procedure should ideally be performed within 72h. Early surgery is associated with better results in comparison to delayed surgery. In addition, when to suspect associated common bile duct stones and how to treat them when found are still debated. The antimicrobial agents are indicated for high-risk patients and especially in the presence of gallbladder necrosis. The use of broad-spectrum antibiotics and in some cases with antifungal agents is related to better prognosis. Moreover, an emerging strategy of not converting to open, a difficult laparoscopic cholecystectomy and performing a subtotal cholecystectomy is recommended by adept surgical teams. Some authors support the use of percutaneous cholecystostomy as an alternative emergency treatment for acute Cholecystitis for patients with severe comorbidities. | Carlos Augusto Gomes Cleber Soares Junior Salomone Di Saveiro Massimo Sartelli Michel Denis Kelly Camila Couto Gomes Felipe Couto Gomes Lívia Dornellas Correa Camila Brandao Alves Samuel de Fádel Guimaraes | 2017 | World Journal of Gastrointestinal Surgery2017，9，5： | 18 |
| 2 | Helicobacter pylori infection: Host immune response, implications on gene expression and microRNAs显示文摘Helicobacter pylori(H. pylori) infection is the most common bacterial infection worldwide. Persistent infection of the gastric mucosa leads to inflammatory processes and may remain silent for decades or progress causing more severe diseases, such as gastric adenocarcinoma. The clinical consequences of H. pylori infection are determined by multiple factors, including host genetic predisposition, gene regulation, environmental factors and heterogeneity of H. pylori virulence factors. After decades of studies of this successful relationship between pathogen and human host, various mechanisms have been elucidated. In this review, we have made an introduction on H. pylori infection and its virulence factors, and focused mainly on modulation of host immune response triggered by bacteria, changes in the pattern of gene expression in H. pylori-infected gastric mucosa, with activation of gene transcription involved in defense mechanisms, inflammatory and immunological response, cell proliferation and apoptosis. We also highlighted the role of bacteria eradication on gene expression levels. In addition, we addressed the recent involvement of different microRNAs in precancerous lesions, gastric cancer, and inflammatory processes induced by bacteria. New discoveries in this field may allow a better understanding of the role of major factors involved in the pathogenic mechanisms of H. pylori. | Aline Cristina Targa Cadamuro Ana Flávia Teixeira Rossi Nathália Maciel Maniezzo Ana Elizabete Silva | 2014 | World Journal of Gastroenterology2014，20，6： | 16 |
| 3 | Helicobacter pylori and EBV in gastric carcinomas:Methylation status and microsatellite instability显示文摘AIM:To verify the methylation status of CDH1, DAPK, COX2, hMLH1 and CDKN2A genes and to evaluate their association with Helicobacter pylori (H. pylori)-cagA+ and Epstein Barr virus (EBV) infections in gastric adenocarcinomas.METHODS: Methylation-specific PCR (MSP) assay was performed in 89 primary gastric carcinomas (intestinal and diffuse types). Microsatellite instability (MSI) analysis was performed using the BAT26 primer set and PCR products were analyzed with the ABI PRISM 3100 Genetic Analyzer using Genescan 3.7 software (Applied Biosystems). Detection of H. pylori and genotyping were performed by PCR, using specifi c primers for ureaseC and cagA genes. The presence of EBV was assessed by in situ hybridization. Statistical analyses were performed using the χ2 or Fisher's exact test.RESULTS: The most frequent hypermethylated gene was COX-2 (63.5%) followed by DAPK (55.7%), CDH1 (51%), CDKN2A (36%) and hMLH1 (30.3%). Intestinal and diffuse adenocarcinomas showed different methylation profiles and there was an association between methylation of E-CDH1 and H. pylori-cagA+ in the intestinal adenocarcinoma type. MSI was correlated with hMLH1 methylation. There was an inverse correlation between DAPK hypermethylation and MSI.CONCLUSION: We found a strong association between CDH1 methylation and H. pylori-cagA+ in intestinal-type gastric cancer, association of MSI and better prognosis and an heterogeneous COX-2 overexpression. | Adriana Camargo Ferrasi Nídia Alice Pinheiro Silvia Helena Barem Rabenhorst Otávia Luisa Caballero Maria Aparecida Marchesan Rodrigues Fabrício de Carvalho Celso Vieira de Souza Leite Marcia Valéria Pitombeira Ferreira Marcos Aurélio Pessoa Barros Maria Inês de Moura Campos Pardini | 2010 | World Journal of Gastroenterology2010，16，3： | 6 |
| 4 | Embolization of splenorenal shunt associated to portal vein thrombosis and hepatic encephalopathy显示文摘Hepatic encephalopathy(HE)is a cognitive disturbance characterized by neuropsychiatric alterations.It occurs in acute and chronic hepatic disease and also in patients with portosystemic shunts.The presence of these portosystemic shunts allows the passage of nitrogenous substances from the intestines through systemic veins without liver depuration.Therefore,the embolization of these shunts has been performed tocontrol HE manifestations,but the presence of portal vein thrombosis is considered a contraindication.In this presentation we show a cirrhotic patient with severe HE and portal vein thrombosis who was submitted to embolization of a large portosystemic shunt.Case report:a 57 years-old cirrhotic patient who had been hospitalized many times for persistent HE and hepatic coma,even without precipitant factors.She had a wide portosystemic shunt and also portal vein thrombosis.The abdominal angiography confirmed the splenorenal shunt and showed other shunts.The larger shunt was embolized through placement of microcoils,and the patient had no recurrence of overt HE.There was a little increase of esophageal and gastric varices,but no endoscopic treatment was needed.Since portosystemic shunts are frequent causes of recurrent HE in cirrhotic patients,portal vein thrombosis should be considered a relative contraindication to perform a shunt embolization.However,in particular cases with many shunts and severe HE,we found that one of these shunts can be safely embolized and this procedure can be sufficient to obtain a good HE recovery.In conclusion,we reported a case of persistent HE due to a wide portosystemic shunt associated with portal vein thrombosis.As the patient had other shunts,she was successfully treated by embolization of the larger shunt. | Letícia de Campos Franzoni Fábio Cardoso de Carvalho Rafael Gomes de Almeida Garzon Fábio da Silva Yamashiro Laís Augusti Lívia Alves Amaral Santos Mariana de Souza Dorna Júlio Pinheiro Baima Talles Bazeia Lima Carlos Antonio Caramori Giovanni Faria Silva Fernando Gomes Romeiro | 2014 | World Journal of Gastroenterology2014，20，42： | 6 |
| 5 | Evolution of Microstructure and Mechanical Property during Long-Term Aging in Udimet 720Li显示文摘Thermal stabilities of microstructure and mechanical property have been investigated on super- alloy U72OLi, which is of great interest of application for jet engine and land-based turbine disc. The results showed that, the primary and secondary γ’?particles maintain good thermal stability at 650 and 7000C with aging time up to 3000 h, while the tertiary γ’?is apparently dependent on aging temperature and time. The tertiary γ’?particles undergo a procedure of coarsening, dissolution and eventually complete disappearance with the increasing of aging time and temper- ature. They exhibit unusual high sensibility upon aging temperature, which is attributed to the lattice misfit between the γ’?precipitates and the matrix in the alloy. The grain boundary phase M23C6 remains stable without forming of sigma phase even with aging time up to 3000 h at 700℃. Microhardness decreases apparently with increasing aging time and aging temperature. Theoretical analysis based on dislocation mechanism indicates that the change of microhardness should be attributed to the evolution of the tertiary γ’?during aging. | Lanzhang ZHOU and Valentino LUPINC CNR-TeMPE, Via R.

| 6 | Upregulation of the APE1 and H2AX genes and miRNAs involved in DNA damage response and repair in gastric cancer显示文摘Gastric cancer remains one of the leading causes of cancer-related death worldwide,and most of the cases are associated with Helicobacter pylori infection.This bacterium promotes the production of reactive oxygen species(ROS),which cause DNA damage in gastric epithelial cells.In this study,we evaluated the expression of important genes involved in the recognition of DNA damage(ATM,ATR,and H2AX)and ROS-induced damage repair(APE1)and the expression of some miRNAs(miR-15a,miR-21,miR-24,miR-421 and miR-605)that target genes involved in the DNA damage response(DDR)in 31 fresh tissues of gastric cancer.Cytoscape v3.1.1 was used to construct the postulated miRNA:mRNA interaction network.Analysis performed by real-time quantitative PCR exhibited significantly increased levels of the APE1(RQ=2.55,p<0.0001)and H2AX(RQ=2.88,p=0.0002)genes beyond the miR-421 and miR-605 in the gastric cancer samples.In addition,significantly elevated levels of miR-21,miR-24 and miR-421 were observed in diffuse-type gastric cancer.Correlation analysis reinforced some of the gene:gene(ATM/ATR/H2AX)and miRNA:mRNA relationships obtained also with the interaction network.Thus,our findings show that tumor cells from gastric cancer presents deregulation of genes and miRNAs that participate in the recognition and repair of DNA damage,which could confer an advantage to cell survival and proliferation in the tumor microenvironment. | Fernanda S.Manoel-Caetano Ana Flávia T.Rossi Gabriela Calvet de Morais Fábio Eduardo Severino Ana Elizabete Silva | 2019 | Genes & Diseases2019，6，2： | 5 |

| 8 | Fluid and electrolyte overload in critically ill patients: An overview显示文摘Fluids are considered the cornerstone of therapy for many shock states, particularly states that are associated with relative or absolute hypovolemia. Fluids are also commonly used for many other purposes, such as renalprotection from endogenous and exogenous substances, for the safe dilution of medications and as 'maintenance' fluids. However, a large amount of evidence from the last decade has shown that fluids can have deleterious effects on several organ functions, both from excessive amounts of fluids and from their non-physiological electrolyte composition. Additionally, fluid prescription is more common in patients with systemic inflammatory response syndrome whose kidneys may have impaired mechanisms of electrolyte and free water excretion. These processes have been studied as separate entities(hypernatremia, hyperchloremic acidosis and progressive fluid accumulation) leading to worse outcomes in many clinical scenarios, including but not limited to acute kidney injury, worsening respiratory function, higher mortality and higher hospital and intensive care unit lengthof-stays. In this review, we synthesize this evidence and describe this phenomenon as fluid and electrolyte overload with potentially deleterious effects. Finally, we propose a strategy to safely use fluids and thereafter wean patients from fluids, along with other caveats to be considered when dealing with fluids in the intensive care unit. | Bruno Adler Maccagnan Pinheiro Besen André Luiz Nunes Gobatto Lívia Maria Garcia Melro Alexandre Toledo Maciel Marcelo Park | 2015 | World Journal of Critical Care Medicine2015，4，2： | 5 |
| 9 | Prognostic significance of vascular endothelial growth factor polymorphisms in colorectal cancer patients显示文摘AIM To investigate the associations of the genetic polymor-phisms of vascular endothelial growth factor A(VEGF-A)-1498C>T and-634G>C, with the survival of patients with colorectal cancer(CRC). METHODS A prospective cohort consisting of 131 Brazilians patients consecutively operated on with a curative intention as a result of sporadic colorectal carcinoma was studied. DNA was extracted from peripheral blood and its amplification and allelic discrimination for each genetic polymorphism was performed using the technique of polymerase chain reaction(PCR) in real-time. The real-time PCR technique was used to identify the VEGF-A-1498C>T(rs833031) and-634G>C(rs2010963) polymorphisms. Genotyping was validated for VEGF-A-1498C>T polymorphism in 129 patients and for VEGF-A-634G>C polymorphism in 118 patients. The analysis of association between categorical variables was performed using logistic regression, survival by Kaplan-Meier method and multivariate analysis by the Cox regression method. RESULTS In the univariate analysis there was a significant association(OR = 0.32; P = 0.048) between genotype CC of the VEGF-A-1498C>T polymorphism and the presence of CRC liver metastasis. There was no association between VEGF-A-1498C>T polymorphism and VEGF-A-634G>C polymorphism with further clinical or anatomopathologic variables. The genotype CC of the VEGF-A-1498C>T polymorphism was significantly correlated with the 5-year survival(P = 0.032), but not significant difference(P = 0.27) was obtained with the VEGF-A-634G>C polymorphism with the 5-year survival in the univariate analysis. The genotype CT(HR = 2.79) and CC(HR = 4.67) of the polymorphism VEGF-A-1498C>T and the genotype CC(HR = 3.76) of the polymorphism VEGF-A-634C>G acted as an independent prognostic factor for the risk of death in CRC patients. CONCLUSION The CT and CC genotypes of the VEGF-A-1498C>T and the CC genotype of the VEGF-A-634C>G polymorphisms are prognostic factors of survival in Brazilians patients with sporadic colorectal carcinoma. | Gilmar Ferreira do Espírito Santo Bianca Borsatto Galera Elisabeth Carmen Duarte Elisabeth Suchi Chen Lenuce Azis Amilcar Sabino Damazo Gabriela Tognini Saba Flávia de Sousa Gehrke Ismael Dale Cotrim Guerreiro da Silva Jaques Waisberg | 2017 | World Journal of Gastrointestinal Oncology2017，9，2： | 4 |
| 10 | Giant hepatic extra-gastrointestinal stromal tumor treated with cytoreductive surgery and adjuvant systemic therapy:A case report and review of literature显示文摘BACKGROUND Primary extra-gastrointestinal stromal tumors(E-GIST)of the liver are rare.The clinical presentation may range from asymptomatic to bleeding or manifestations of mass effect.Oncologic surgery followed by adjuvant therapy with imatinib is the standard of care.However,under specific circumstances,a cytoreductive approach may represent a therapeutic option.We describe herein the case of an 84-year-old woman who presented with a tender,protruding epigastric mass.Abdominal computed tomography scan revealed a large,heterogeneous mass located across segments III,IV,V,and VIII of the liver.The initial approach was transarterial embolization of the tumor,which elicited no appreciable response.Considering the large size and central location of the tumor and the advanced age of the patient,non-anatomic complete resection was indicated.Due to substantial intraoperative bleeding and hemodynamic instability,only a near-complete resection could be achieved.Histopathology and immunohistochemical staining confirmed the diagnosis of primary E-GIST of the liver.Considering the risk/benefit ratio for therapeutic options,debulking surgery may represent a strategy to control pain and prolong survival.CASE SUMMARY Here,we present a case report of a patient diagnosed with E-GIST primary of the liver,which was indicated a cytoreductive surgery and adjuvant therapy with imatinib.CONCLUSION E-GIST primary of the liver is a rare conditional,the treatment is with systemic therapy and total resection surgery.However,a cytoreductive surgery will be necessary when a complete resection is no possible. | Michel Ribeiro Fernandes Caroline Lorenzoni Almeida Ghezzi Tomaz J M Grezzana-Filho Flávia Heinz Feier Ian Leipnitz Aljamir Duarte Chedid Carlos Thadeu Schmidt Cerski Marcio Fernandes Chedid Cléber RositoPinto Kruel | 2021 | World Journal of Gastrointestinal Surgery2021，13，3： | 3 |
| 11 | Mangiferin,a natural xanthone,accelerates gastrointestinal transit in mice involving cholinergic mechanism显示文摘AIM:To investigate the effects of mangiferin on gastrointestinal transit(GIT) in normal and constipated mice,together with the possible mechanism.METHODS:Intragastrically-administered charcoal mealwas used to measure GIT in overnight starved Swiss mice.In the first experiments,mangiferin(3 mg/kg,10 mg/kg,30 mg/kg,and 100 mg/kg,po) or tegaserod(1 mg/kg,ip) were administered 30 min before the charcoal meal to study their effects on normal transit.In the second series,mangiferin(30 mg/kg) was tested on delayed GIT induced by several different pharmacological agonists(morphine,clonidine,capsaicin) or antagonists(ondansetron,verapamil,and atropine) whereas in the third series,mangiferin(30 mg/kg,100 mg/kg and 300 mg/kg) or tegaserod(1 mg/kg) were tested on 6 h fecal pellets outputted by freely fed mice.The ratio of wet to dry weight was calculated and used as a marker of fecal water content.RESULTS:Mangiferin administered orally significantly(P < 0.05) accelerated GIT at 30 mg/kg and 100 mg/kg(89% and 93%,respectively),similarly to 5-hydroxytryptamine4(5-HT4) agonist tegaserod(81%) when compared to vehicle-treated control(63%).Co-administered mangiferin(30 mg/kg) totally reversed the inhibitory effect of opioid agonist morphine,5-HT3-receptor antagonist ondansetron and transient receptor potential vanilloid-1 receptor agonist capsaicin on GIT,but only to a partial extent with the GIT-delay induced by 2-adrenoceptor agonist clonidine,and calcium antagonist verapamil.However,co-administered atropine completely blocked the stimulant effect of mangiferin on GIT,suggesting the involvement of muscarinic acetylcholine receptor activation.Although mangiferin significantly enhanced the 6 h fecal output at higher doses(245.5 ± 10.43 mg vs 161.9 ± 10.82 mg and 227.1 ± 20.11 mg vs 161.9 ± 10.82 mg of vehicle-treated control,at 30 and 100 mg/kg,P < 0.05,respectively),the effect of tegaserod was more potent(297.4 ± 7.42 mg vs 161.9 ± 10.82 mg of vehicle-treated control,P < 0.05).Unlike tegaserod,which showed an enhanced water content in fecal pellets(59.20% ± 1.09% vs 51.44% ± 1.19% of control,P < 0.05),mangiferin evidenced no such effect,indi-cating that it has only a motor and not a secretomotor effect.CONCLUSION:Our data indicate the prokinetic action of mangiferin.It can stimulate the normal GIT and also overcome the drug-induced transit delay,via a cholinergic physiological mechanism. | Talita Cavalcante Morais Synara Cavalcante Lopes Karine Maria Martins Bezerra Carvalho Bruno Rodrigues Arruda Francisco Thiago Correia de Souza Maria Teresa Salles Trevisan Vietla Satyanarayana Rao Flávia Almeida Santos | 2012 | World Journal of Gastroenterology2012，18，25： | 3 |
| 12 | In vitro Effect of Dithiocarbamate Pesticides and of CaNa_2EDTA on Human Serum Dopamine-β-hydroxylase显示文摘Serum dopamine-β-hydroxylase (DBH) inhibition has been reported in lead workers treated with CaNa2EDTA and in alcoholic patients repeatedly treated with the alcohol aversive drug Disulfiram. The mechanism of inhibition involves Cu-chelation at the active site of DBH. The effect of CaNa2EDTA and Disulfiram on serum DBH has been compared to the effect of dithiocarbamate pesticides in vitro for the possible use of serum DBH determination for the biological monitoring of workers exposed to these pesticides.Most dithiocarbamates inhibit human serum DBH at micromoIar concentrations (range of I50, 0.027-1.6 μmol/L). The inhibitory potency increased from methyl- and dimethyl dithiocarbamates to diethyl dithiocarbamates up to the most potent ethylene bisdithiocarbamates. The I50 of CaNa.EDTA was 3.8 mol/L, higher than those of dithiocarbamates. Copper addition to the test system rcactivated at stoichiometric concentrations dithiocarbamaie-inhibited DBH indicating that both base line values and percent of inhibition can be calculated in a single blood sample. Results suggest that serum DBH determination couId be useful in case of acute poisoning involving high doses of dithiocarbamate | PAOLA DE PARIS AND STEFANO CAROLDI(Istituto di Medicina del Lavoro, Universita’ di Padova, Padova, Italy)(Send correspondence to: Dr. Stefano Caroldi.

| 15 | Papillary fistulotomy vs conventional cannulation for endoscopic biliary access:A prospective randomized trial显示文摘AIM To compare the cannulation success, biochemical profile, and complications of the papillary fistulotomy technique vs catheter and guidewire standard access.METHODS From July 2010 to May 2017, patients were prospectively randomized into two groups: Cannulation with a catheter and guidewire(Group Ⅰ) and papillary fistulotomy(Group Ⅱ). Amylase, lipase and C-reactive protein at T0, as well as 12 h and 24 h after endoscopic retrograde cholangiopancreatography, and complications(pancreatitis, bleeding, perforation) were recorded.RESULTS We included 102 patients(66 females and 36 males, mean age 59.11 ± 18.7 years). Group Ⅰ and Group Ⅱ had 51 patients each. The successful cannulation rates were 76.5% and 100%, respectively(P = 0.0002). Twelve patients(23.5%) in Group Ⅰ had a difficult cannulation and underwent fistulotomy, which led to successful secondary biliary access(Failure Group). The complication rate was 13.7%(2 perforations and 5 mild pancreatitis) vs 2.0%(1 patient with perforation and pancreatitis) in Groups Ⅰ and Ⅱ, respectively(P = 0.0597). CONCLUSION Papillary fistulotomy was more effective than guidewire cannulation, and it was associated with a lower profile of amylase and lipase. Complications were similar in both groups. | Carlos Kiyoshi Furuya Paulo Sakai Fabio Ramalho Tavares Marinho Jose Pinhata Otoch Spencer Cheng Lívia Lemes Prudencio Eduardo Guimaraes Hourneaux de Moura Everson Luiz de Almeida Artifon | 2018 | World Journal of Gastroenterology2018，24，16： | 2 |
| 16 | Influence of gender in the recognition of basic facial expressions:A critical literature review显示文摘AIM: To conduct a systematic literature review about the influence of gender on the recognition of facial expressions of six basic emotions. METHODS: We made a systematic search with the search terms(face OR facial) AND(processing OR recognition OR perception) AND(emotional OR emotion) AND(gender or sex) in Pub Med, Psyc INFO, LILACS, and Sci ELO electronic databases for articles assessing outcomes related to response accuracy and latency and emotional intensity. The articles selection was performed according to parameters set by COCHRANE. The reference lists of the articles found through the database search were checked for additional references of interest. RESULTS: In respect to accuracy, women tend to perform better than men when all emotions are considered as a set. Regarding specific emotions, there seems to be no gender-related differences in the recognition of happiness, whereas results are quite heterogeneous in respect to the remaining emotions, especially sadness, anger, and disgust. Fewer articles dealt with the parameters of response latency and emotional intensity, which hinders the generalization of their findings, especially in the face of their methodological differences. CONCLUSION: The analysis of the studies conducted to date do not allow for definite conclusions concerning the role of the observer's gender in the recognition of facial emotion, mostly because of the absence of standardized methods of investigation. | Larissa Forni-Santos Flávia L Osório | 2015 | World Journal of Psychiatry2015，5，3： | 2 |
| 17 | Channel Mismatching in Sidelobe Canceler: Limitations and Remedies显示文摘After a brief recall of the Sidelobe Canceler (SLC) working principle, including the derivation of a general formula for the Cancellation Ratio (CR), the effects of channel mismatching are investigated. In particular, curves providing CRvalues as a function of amplitude and phase channel mismatching, radar bandwidth, and jammer direction of arrival (JDOA) are provided for the cases of one and two auxiliary antennas. Subsequently, a time -space processor for performance restoration is analyzed in detail. In addition to the above mentioned quantities, the attainable CR value is expressed as a function of the space-time processor parameters. The contribution of the paper is related to the derivation of a number of mathematical equations of CR for several cases of practical interest for the radar engineer. In addition, several curves are presented to assist design of SLC systems. | A. Farina and A. ProtopapaRadar Dpt Selenia S. p.

| 18 | Extramedullary plasmocytoma associated with a massive deposit of amyloid in the duodenum显示文摘We report a rare case of extramedullary plasmocytoma associated with a massive deposit of amyloid in the duodenum.A 72-year-old Japanese man was admitted to our hospital presenting with a 3-mo history of epigastric pain, vomiting and weight loss.On computed tomography(CT) a wall thickening of the fourth part of the duodenum was observed.Multiple biopsies obtained from the lesion showed inflltration of plasma cells and lymphocytes, but they were not conclusive.The patient underwent resection of the lesion and, on histopathological examination, the lesion consisted of a dense and diffuse inflltrate of plasma cells and a few admixed lymphocytes with reactive follicles extending to the muscular propria.An extensive deposition of amyloid was also observed.Immunohistochemical stains revealed that a few plasmacytoid cells showed λ light chain staining, though most were κ light chain positive.These cells also were positive for CD138 and CD56 but negative for CD20 and CD79.The flndings were consistent with extramedullary plasmocytomaassociated with a massive deposit of amyloid in duodenum.A subsequent workup for multiple myeloma was completely negative.The patient showed no signs of local recurrence or dissemination of the disease after 12 mo follow-up.Because of the association of plasmocytoma and amyloidosis, the patient must be followed up because of the possible systemic involvement of the neoplasm and amyloidosis in future. | Fabiana Pirani Carneiro Maria de Nazareth Machado Sobreira Lívia Bravo Maia Alesso Cervantes Sartorelli Luiz Eduardo de Almeida Prado Franceschi Mauro Brito Brando Bárbara Wosnjuk Calaca Fernando Silva Lustosa Joo Vieira Lopes | 2009 | World Journal of Gastroenterology2009，15，28： | 2 |
| 19 | Chronic pelvic pain,psychiatric disorders and early emotional traumas:Results of a cross sectional case-control study显示文摘AIM To compare the prevalence of psychiatric disorders and early emotional traumas between women with chronic pelvic pain(CPP) and healthy women.METHODS One hundred women in reproductive age,50 of them had CPP(according to the criteria set by the International Association for Study of Pain),and 50 were considered healthy after the gynecological evaluation.The eligibility criteria were defined as follows:chronic or persistent pain perceived in the pelvis-related structures(digestive,urinary,genital,myofascial or neurological systems).Only women in reproductive age with acyclic pain for 6 mo,or more,were included in the present study.Menopause was the exclusion criterion.The participants were grouped according to age,school level and socioeconomic status and were individually assessed through DSM-IV Structured Clinical Interview(SCID-I) and Early Trauma Inventory Self-report-short form(ETISR-SF Brazilian version).Descriptive statistics,group comparison tests and multivariate logistics regression were used in the data analysis.RESULTS The early emotional traumas are highly prevalent,but their prevalence did not differ between the two groups.The current Major Depressive Disorder was more prevalent in women with CPP.The CPP was associatedwith endometriosis in 48% of the women.There was no difference in the prevalence of disorders when endometriosis was taken into account(endometriosis vs other diseases:P > 0.29).The current Major Depressive Disorder and the Bipolar Disorder had greater occurrence likelihood in the group of women with CPP(ODDS = 5.25 and 9.0).CONCLUSION The data reinforce the link between mood disorders and CPP.The preview evidences about the association between CPP and early traumas tended not to be significant after a stronger methodological control was implemented. | Flávia L Osório Ana Carolina F Carvalho Mariana F Donadon André L Moreno Omero Polli-Neto | 2016 | World Journal of Psychiatry2016，6，3： | 2 |
| 20 | Role of diet and nutrition in inflammatory bowel disease显示文摘Inflammatory bowel diseases(IBDs)are closely linked to nutrition.The latest research indicates that diet and nutrition are significantly involved in the etiopathogenesis of the disease,although their specific role throughout its clinical course still remains unclear.This study reviewed how diet and nutrition are associated with IBD development and management.Even though specific diets have been shown to bring about positive outcomes,there is currently no scientific consensus regarding an appropriate diet that would benefit all IBD patients.We suggest that individualized dietary recommendations are of the greatest importance and that diets should be planned to provide individual IBD patients with specific nutrient requirements while keeping all the clinical aspects of the patients in mind.Further research is clearly necessary to investigate nutritional factors involved in IBD development and,especially,to evaluate the applications of the diets during the course of the disease. | Marina Moreira de Castro Lívia Bitencourt Pascoal Karine Mariane Steigleder Beatriz Piatezzi Siqueira Ligiana Pires Corona Maria de Lourdes Setsuko Ayrizono Marciane Milanski Raquel Franco Leal | 2021 | World Journal of Experimental Medicine2021，11，1： | 2 |
