| 1 | Diabetes and cancer:Looking at the multiligand/RAGE axis显示文摘The association between diabetes and hyperglycemia and the associated increased risk of several solid and hematologic malignancies has been the subject of investigation for many years.Although the association is not fully understood,current knowledge clearly indicates that diabetes may influence malignant cell transformation by several mechanisms,including hyperinsulinemia,hyperglycemia and chronic inflammation.In this context,the receptor for advanced glycation end-products (RAGE) has emerged as a focal point in its contribution to malignant transformation and tumor growth.We high-light how RAGE,once activated,as it manifests itself in conditions such as diabetes or hyperglycemia,is able to continuously bring about an inflammatory milieu,thus supporting the contribution of chronic inflammation to the development of malignancies. | Armando Rojas Ileana González Erik Morales Ramón Pérez-Castro Jacqueline Romero Héctor Figueroa | 2011 | World Journal of Diabetes2011，2，7： | 11 |
| 2 | Timely reperfusion for ST-segment elevation myocardial infarction:Effect of direct transfer to primary angioplasty on time delays and clinical outcomes显示文摘Primary percutaneous coronary intervention(PPCI) is the preferred reperfusion therapy for patients presenting with ST-segment elevation myocardial infarction(STEMI) when it can be performed expeditiously and by experienced operators. In spite of excellent clinical results this technique is associated with longer delays than thrombolysis and this fact may nullify the benefit of selecting this therapeutic option. Several strategies have been proposed to decrease the temporal delays to deliver PPCI. Among them,prehospital diagnosis and direct transfer to the cath lab,by-passing the emergency department of hospitals,has emerged as anattractive way of diminishing delays. The purpose of this review is to address the effect of direct transfer on time delays and clinical events of patients with STEMI treated by PPCI. | Rodrigo Estévez-Loureiro ángela López-Sainz Armo Pérez de Prado Carlos Cuellas Ramón Calvio Santos Norberto Alonso-Orcajo Jorge Salgado Fernández Jose Manuel Vázquez-Rodríguez Maria López-Benito Felipe Fernández-Vázquez | 2014 | World Journal of Cardiology2014，6，6： | 6 |
| 3 | Increased incidence of and microbiologic changes in pyogenic liver abscesses in the Mexican population显示文摘BACKGROUND Pyogenic liver abscess(PLA)is a rare disease with an estimated incidence that varies widely across the globe,being as high as 115.4/100000 habitants in Taiwan and as low as 1.1-1.2/100000 habitants in Europe and Canada.Even though there are multiple microorganisms capable of producing an abscess in the liver,including Entamoeba histolytica,fungi,and viruses,most abscesses are derived from bacterial infections.The epidemiology of PLA in Mexico is currently unknown.AIM To describe the clinical,demographic and microbiologic characteristics of PLA in Mexico.METHODS This is a retrospective study carried out in two centers,and included patients seen between 2006 and 2018 with the diagnosis of pyogenic abscess.We collected demographic,clinical,and microbiological information,treatment,complications,and outcomes.A logistic regression analysis was used to determine the association between different variables and mortality rates.RESULTS A total of 345 patients were included in this study.233(67.5%)had confirmed PLA,133(30%)patients had no positive culture and negative serology and 9(2.5%)had mixed abscesses.The mean age was 50 years(ranging from 16-97 years)and 63%were female.65%of the patients had positive cultures for Extended Spectrum Beta-Lactamases(ESBL)-Escherichia coli and Klebsiella pneumoniae.Cefotaxime was administered in 60%of cases.The most common sources of infection were ascending cholangitis and cholecystitis in 34(10%)and 31(9%),respectively.The median length of hospital stay was 14 d.165 patients underwent percutaneous catheter drainage.The inpatient mortality rate was 63%.Immunocompromised state[OR 3.9,95%CI:1.42-10.46],ESBL-Escherichia coli[OR 6.7,95%CI:2.7-16.2]and Klebsiella pneumoniae[OR 4-8,95%CI:1.6-14.4]predicted inpatient mortality by multivariate analysis.CONCLUSION The prevalence of PLA is increasing in Mexico and has a very high mortality rate.ESBL-Escherichia coli and Klebsiella pneumoniae are the most common microorganisms causing PLA and are independent predictors of inpatient mortality. | Juanita Pérez-Escobar Wagner Ramirez-Quesada Daniel Alejandro Calle-Rodas Luis Alberto Chi-Cervera Nalu Navarro-Alvarez Jorge Aquino-Matus Juan Pablo Ramírez-Hinojosa Carlos Moctezuma-Velázquez Aldo Torre | 2020 | World Journal of Hepatology2020，12，10： | 5 |
| 4 | Effectiveness of an intervention for reducing social stigma towards mental illness in adolescents显示文摘AIM: To evaluate the effectiveness of an intervention for reducing social stigma towards mental illness in adolescents. The effect of gender and knowledge of someone with mental illness was measured. METHODS: Two hundred and eighty secondary school students were evaluated using the Community Attitudes towards Mental Illness(CAMI) questionnaire. The schools were randomized and some received the intervention and others acted as the control group. The programme consisted of providing information via a documentary film and of contact with healthcare staff in order to reduce the social stigma within the school environment. RESULTS: The intervention was effective in reducing the CAMI authoritarianism and social restrictiveness subscales. The intervention showed significant changes in girls in terms of authoritarianism and social restrictiveness, while boys only showed significant changes in authoritarianism. Following the intervention, a significant reduction was found in authoritarianism and social restrictiveness in those who knew someone with mental illness, and only in authoritarianism in those who did not know anyone with mental illness. CONCLUSION: The intervention was effective to reduce social stigma towards people with mental illness, especially in the area of authoritarianism. Some differences were found depending on gender and whether or not the subjects knew someone with mental illness. | Regina Vila-Badia Francisco Martínez-Zambrano Otilia Arenas Emma Casas-Anguera Esther García-Morales Raúl Villellas José Ramón Martín María Belén Pérez-Franco Tamara Valduciel Diana Casellas Mar García-Franco Jose Miguel Joaquim Balsera Gemma Pascual Eugènia Julia Susana Ochoa | 2016 | World Journal of Psychiatry2016，6，2： | 4 |
| 5 | Novel nutraceutic therapies for the treatment of metabolic syndrome显示文摘Nutraceutic therapies such as berberine, bitter melon,Gymnema sylvestre, Irvingia gabonensis, resveratrol and ursolic acid have been shown to help control metabolic syndrome(MetS). The effect of berberine on glucose and lipid metabolism, hypertension, obesity and MetS has been evaluated in animal models and humans. Most clinical trials involving bitter melon have been conducted to evaluate its effect on glucose metabolism; nevertheless, some studies have reported favorable effects on lipids and blood pressure although there is little information about its effect on body weight. Gymnema sylvestre helps to decrease body weight and blood sugar levels; however, there is limited information on dyslipidemia and hypertension. Clinical trials of Irvingia gabonensis have shown important effects decreasing glucose and cholesterol concentrations as well decreasing body weight. Resveratrol acts through different mechanisms to decrease blood pressure, lipids, glucose and weight, showing its effects on the population with Met S. Finally, there is evidence of positive effects with ursolic acid in in vitro and in vivo studies on glucose and lipid metabolism and on body weight and visceral fat. Therefore, a review of the beneficial effects and limitations of the above-mentioned nutraceutic therapies is presented. | Esperanza Martínez-Abundis Miriam Mendez-del Villar Karina G Pérez-Rubio Laura Y Zuniga Marisol Cortez-Navarrete Alejandra Ramírez-Rodriguez Manuel González-Ortiz | 2016 | World Journal of Diabetes2016，7，7： | 3 |
| 6 | Preclinical evaluation of azathioprine plus buthionine sulfoximine in the treatment of human hepatocarcinoma and colon carcinoma显示文摘AIM: To evaluate the efficacy and the safety of azathioprine (AZA) and buthionine sulfoximine (BSO) bylocalized application into HepG2 tumor in vivo.METHODS: Different hepatoma and colon carcinoma cell lines (HepG2, HuH7, Chang liver, LoVo, RKO, SW-48, SW-480) were grown in minimal essencial medium supplemented with 10% fetal bovine serum and 1% antibiotic/antimycotic solution and maintained in a humidified 37 ℃ incubator with 5% CO2. These cells were pretreated with BSO for 24 h and then with AZA for different times. We examined the effects of this combination on some proteins and on cellular death. We also studied the eff icacy and the safety of AZA (6 mg/kg per day) and BSO (90 mg/kg per day) in HepG2 tumor growth in vivo using athymic mice. We measured safety by serological markers such as aminotransferases and creatine kinase.RESULTS: The in vitro studies revealed a new mechanism of action for the AZA plus BSO combination in the cancer cells compared with other thiopurines (6-mercaptopurine, 6-methylmercaptopurine, 6-thioguanine and 6-methylthioguanine) in combination with BSO. The cytotoxic effect of AZA plus BSO in HepG2 cells resulted from necroptosis induction in a mitochondrial-dependent manner. From kinetic studies we suggest that glutathione (GSH) depletion stimulates c-Jun amino-terminal kinase and Bax translocation in HepG2 cells with subsequent deregulation of mitochondria (cytochrome c release, loss of membrane potential), and proteolysis activation leading to loss of membrane integrity, release of lactate dehydrogenase and DNA degradation. Some of this biochemical and cellular changes could be reversed by N-acetylcysteine (a GSH replenisher). In vivo studies showed that HepG2 tumor growth was inhibited when AZA was combined with BSO.CONCLUSION: Our studies suggest that a combination of AZA plus BSO could be useful for localizedtreatment of hepatocellular carcinoma as in the currently used transarterial chemoembolization method. | Borja Hernández-Breijo Jorge Monserrat Sara Ramírez-Rubio Eva P Cuevas Diana Vara Inés Díaz-Laviada M Dolores Fernández-Moreno Irene D Román Javier P Gisbert Luis G Guijarro | 2011 | World Journal of Gastroenterology2011，17，34： | 2 |
| 7 | Nutritional Status,Sarcopenia and the Importance of Prehabilitation of Gastrointestinal Tumor Patients:a Surgical Point of View显示文摘Background Surgery may be the field of healthcare where malnutrition and sarcopenia have their greatest impact on patient morbidity and mortality.However,there are limited data on the nutritional status of surgical patients and the effects of prehabilitation on the outcomes of surgery.Methods A prospective analysis was conducted on all patients surgically-treated for malignant gastrointestinal tumors at St.John Hospital during a two-year period.The patient’s gender,age,body weight,height,BMI and weight loss were registered,then a risk score was determined by the MUST survey.Measurement of the triceps and thigh skin-fold thickness and the circumference of the upper arm and thigh were done to calculate muscle area and muscle index,respectively.The body composition was assessed using an OMRON-BF511 device.Muscle function was evaluated based on hand clamping force measurement and activity tests.Patients who were diagnosed as being at-risk received preoperative prehabilitation,which included physiotherapy and nutritional therapy.Results A total of 231 patients(133 males/98 females)were analyzed.They had a mean age of 68.9 years(18~98).Seventy-four patients(32%)lost weight,with an average loss of 7 kilograms(3~15 kg).Anthropometric data showed an average upper-arm circumference of 27.4 cm(14.3~38.1)and thigh circumference of 44.7 cm(19.3~60.1),so the median muscle index was 1.29.The mean BMI was 26,which is above normal,and the elevated BMI was consistent documented in each patient subgroup stratified by age and tumor type.A body composition analysis was performed for 75 patients(44 male/31 female),who had a median age of 68(37~88 y).The average BMI of these patients was 25.7 y and their average MUST score was 1.12.The total body fat percentage(of the total body mass)was 29.5%,total muscle was 30.1%and visceral fat was 10%.Thirty patients(40%)had sarcopenia,with a mean BMI of 28.7,fat comprising 34.2%of the body mass,visceral-fat 11%,and muscle 27.1%,and their median MUST score was 1.23.Patients who received preoperative training(physiotherapy)showed improvements in physical function ranging from 12%~33%.Conclusion Gastrointestinal tumor patients have a higher than normal BMI regardless of age or tumor type.Patients with sarcopenia show measurable improvement after two weeks of prehabilitation. | Péter Lukovich Ákos Nagy Bianka Barok Borbála Csiba Ram Rokka Balázs Pőcze | 2020 | Journal of Nutritional Oncology2020，5，3： | 2 |
| 8 | Relation of atrophic gastritis with Helicobacter pylori-CagA^+ and interleukin-1 gene polymorphisms显示文摘AIM: To determine the association of Helicobacter pylori (H pylori) CagA+ infection and pro-inflammatory poly-morphisms of the genes interleukin (IL)-1RN and IL-1B with the risk of gastric atrophy and peptic ulcers in a dyspeptic population in Costa Rica, a country with high incidence and mortality of gastric cancer. METHODS: Seven biopsy specimens, a fasting blood sample and a questionnaire concerning nutritional and sociodemographic factors were obtained from 501 con-secutive patients who had undergone endoscopy for dyspeptic symptoms. A histopathological diagnosis was made. Pepsinogen concentrations were analyzed by enzyme linked immunosorbent assay (ELISA). Infection with H pylori CagA+ was determined by serology and polymerase chain reaction (PCR). IL-1B and IL-1RN polymorphisms genotyping was performed by PCR-restriction fragment length polymorphism (PCR-RFLP)and PCR respectively. RESULTS: In this dyspeptic population, 86% were H pylori positive and of these, 67.8% were positive for CagA. Atrophic antral gastritis (AAG) was associated with CagA+ status [odd ratio (OR) = 4.1; P < 0.000] and fruit consumption (OR = 0.3; P < 0.00). Atrophic body gastritis (ABG) was associated with pepsinogen PGI/PGII < 3.4 (OR = 4.9; P < 0.04) and alcohol consumption (OR = 7.3; P < 0.02). Duodenal ulcer was associated with CagA+ (OR = 2.9; P < 0.04) and smoking (OR = 2.4; P < 0.04). PGI < 60 μg/L as well as PGI/PGII < 3.4 were associated with CagA+. CONCLUSION: In a dyspeptic population in Costa Rica, H pylori CagA+ is not associated with ABG, but it is a risk factor for AAG. The pro-inflammatory cytokine poly-morphisms IL-1B + 3945 and IL-1RN are not associated with the atrophic lesions of this dyspeptic population. | Rafaela Sierra Clas Une Vanessa Ramírez Warner Alpízar-Alpízar María I González José A Ramírez Antoine de Mascarel Patricia Cuenca Guillermo Pérez-Pérez Francis Mégraud | 2008 | World Journal of Gastroenterology2008，14，42： | 2 |
| 9 | Factors associated with early virological response to peginterferon-α-2a/ribavirin in chronic hepatitis C显示文摘AIM: To evaluate the impact of sociodemographic/clinical factors on early virological response (EVR) to pegin-terferon/ribavirin for chronic hepatitis C (CHC) in clinical practice. METHODS: We conducted a multicenter, cross-sectional, observational study in Hepatology Units of 91 Spanish hospitals. CHC patients treated with peginterferon α-2a plus ribavirin were included. EVR was defined as undetectable hepatitis C virus (HCV)-ribonucleic acid (RNA) or ≥ 2 log HCV-RNA decrease after 12 wk of treatment. A bivariate analysis of sociodemographic and clinical variables associated with EVR was carried out. Independent factors associated with an EVR were analyzed using a multiple regression analysis that included the following baseline demographic and clinical variables: age (≤ 40 years vs > 40 years), gender, race, educational level, marital status and family status, weight, alcohol and tobacco consumption, source of HCV infection, alanine aminotransferase (ALT) and aspartate aminotransferase (AST) levels, and gamma glutamyl transpeptidase (GGT) (≤ 85 IU/mL vs > 85 IU/mL), serum ferritin, serum HCV-RNA concentration (< 400 000 vs ≥ 400 000), genotype (1/4 vs 3/4), cirrhotic status and ribavirin dose (800/1000/1200 mg/d).RESULTS: A total of 1014 patients were included in the study. Mean age of the patients was 44.3 ± 9.8 years, 70% were male, and 97% were Caucasian. The main sources of HCV infection were intravenous drug abuse (25%) and blood transfusion (23%). Seventyeight percent were infected with HCV genotype 1/4 (68% had genotype 1) and 22% with genotypes 2/3. The HCV-RNA level was > 400 000 IU/mL in 74% of patients. The mean ALT and AST levels were 88.4 ± 69.7 IU/mL and 73.9 ± 64.4 IU/mL, respectively, and mean GGT level was 82 ± 91.6 IU/mL. The mean ferritin level was 266 ± 284.8 μg/L. Only 6.2% of patients presented with cirrhosis. All patients received 180 mg of peginterferon α-2a. The most frequently used ribavirin doses were 1000 mg/d (41%) and 1200 mg/d (41%). The planned treatment duration was 48 wk for 92% of patients with genotype 2/3 and 24 wk for 97% of those with genotype 1/4 (P < 0.001). Seven percent of patients experienced at least one reduction in ribavirin or peginterferon α-2a dose, respectively. Only 2% of patients required a dose reduction of both drugs. Treatment was continued until week 12 in 99% of patients. Treatment compliance was ≥ 80% in 98% of patients. EVR was achieved in 87% of cases (96% vs 83% of patients with genotype 2/3 and 1/4, respectively; P < 0.001). The bivariate analysis showed that patients who failed to achieve EVR were older (P < 0.005), had higher ALT (P < 0.05), AST (P < 0.05), GGT (P < 0.001) and ferritin levels (P < 0.001), a diagnosis of cirrhosis (P < 0.001), and a higher baseline viral load (P < 0.05) than patients reaching an EVR. Age < 40 years [odds ratios (OR): 0.543, 95%CI: 0.373-0.790, P < 0.01], GGT < 85 IU/mL (OR: 3.301, 95%CI: 0.192-0.471, P < 0.001), low ferritin levels (OR: 0.999, 95%CI: 0.998-0.999, P < 0.01) and genotype other than 1/4 (OR: 4.716, 95%CI: 2.010-11.063, P < 0.001) were identified as independent predictors for EVR in the multivariate analysis. CONCLUSION: CHC patients treated with peginterferon-α-2a/ribavirin in clinical practice show high EVR. Older age, genotype 1/4, and high GGT were associated with lack of EVR. | Javier García-Samaniego Miriam Romero Rafael Granados Remedios Alemán Miguel Jorge Juan Dolores Suárez Ramón Pérez Gregorio Castellano Carlos González-Portela | 2013 | World Journal of Gastroenterology2013，19，12： | 2 |

| 11 | Peripheral arterial disease, type 2 diabetes and postprandial lipidaemia: Is there a link?显示文摘Peripheral arterial disease, manifested as intermittent claudication or critical ischaemia, or identified by an ankle/brachial index < 0.9, is present in at least one in every four patients with type 2 diabetes mellitus.Several reasons exist for peripheral arterial disease indiabetes. In addition to hyperglycaemia, smoking and hypertension, the dyslipidaemia that accompanies type2 diabetes and is characterised by increased triglyceride levels and reduced high-density lipoprotein cholesterol concentrations also seems to contribute to this association. Recent years have witnessed an increased interest in postprandial lipidaemia, as a result of various prospective studies showing that non-fasting triglycerides predict the onset of arteriosclerotic cardiovascular disease better than fasting measurements do. Additionally,the use of certain specific postprandial particle markers,such as apolipoprotein B-48, makes it easier and more simple to approach the postprandial phenomenon. Despite this, only a few studies have evaluated the role of postprandial triglycerides in the development of peripheral arterial disease and type 2 diabetes. The purpose of this review is to examine the epidemiology and risk factors of peripheral arterial disease in type 2 diabetes, focusing on the role of postprandial triglycerides and particles. | Pedro Valdivielso José Ramírez-Bollero Carmen Pérez-López | 2014 | World Journal of Diabetes2014，5，5： | 2 |
| 12 | Current trends of liver cirrhosis in Mexico: Similitudes and differences with other world regions显示文摘AIM To investigate the main current etiologies of cirrhosis in Mexico.METHODS We performed a cross-sectional retrospective multicenter study that included eight hospitals in different areas of Mexico. These hospitals provide health care to people of diverse social classes. The inclusion criteria were a histological, clinical, biochemical, endoscopic, or imaging diagnosis of liver cirrhosis. Data were obtained during a 5-year period(January 2012-December 2017). RESULTS A total of 1210 patients were included. The mean age was 62.5 years(SD = 12.1), and the percentages of men and women were similar(52.0% vs 48.0%). The most frequent causes of liver cirrhosis were hepatitis C virus(HCV)(36.2%), alcoholic liver disease(ALD)(31.2%), and nonalcoholic steatohepatitis(23.2%), and the least frequent were hepatitis B virus(1.1%), autoimmune disorders(7.3%), and other conditions(1.0%).CONCLUSION HCV and ALD are the most frequent causes of cirrhosis in Mexico. However, we note that non-alcoholic fatty liver disease(NAFLD) as an etiology of cirrhosis increased by 100% compared with the rate noted previously. We conclude that NAFLD will soon become one of the most frequent etiologies of liver cirrhosis in Mexico. | Nahum Méndez-Sánchez Felipe Zamarripa-Dorsey Arturo Panduro Emma Purón-González Edgar Ulises Coronado-Alejandro Carlos Alejandro Cortez-Hernández Fátima Higuera de la Tijera José Luis Pérez-Hernández Eira Cerda-Reyes Heriberto Rodríguez-Hernández Vania César Cruz-Ramón Oscar Lenin Ramírez-Pérez Nancy Edith Aguilar-Olivos Olga Fabiola Rodríguez-Martínez Samantha Cabrera-Palma Guillermo Cabrera-álvarez | 2018 | World Journal of Clinical Cases2018，6，15： | 2 |
