| 1 | Differential diagnosis in inflammatory bowel disease colitis:State of the art and future perspectives显示文摘Distinction between Crohn's disease of the colonrectum and ulcerative colitis or inflammatory bowel disease(IBD) type unclassified can be of pivotal importance for a tailored clinical management,as each entity often involves specific therapeutic strategies and prognosis.Nonetheless,no gold standard is available and the uncertainty of diagnosis may frequently lead to misclassification or repeated examinations.Hence,we have performed a literature search to address the problem of differential diagnosis in IBD colitis,revised current and emerging diagnostic tools and refined disease classification strategies.Nowadays,the differential diagnosis is an untangled issue,and the proper diagnosis cannot be reached in up to 10% of patients presenting with IBD colitis.This topic is receiving emerging attention,as medical therapies,surgical approaches and leading prognostic outcomes require more and more disease-specific strategies in IBD patients.The optimization of standard diagnostic approaches based on clinical features,biomarkers,radiology,endoscopy and histopathology appears to provide only marginal benefits.Conversely,emerging diagnostic techniques in the field of gastrointestinal endoscopy,molecular pathology,genetics,epigenetics,metabolomics and proteomics have already shown promising results.Novel advanced endoscopic imaging techniques and biomarkers can shed new light for the differential diagnosis of IBD,better reflecting diverse disease behaviors based on specific pathogenic pathways. | Gian Eugenio Tontini Maurizio Vecchi Luca Pastorelli Markus F Neurath Helmut Neumann | 2015 | World Journal of Gastroenterology2015，21，1： | 13 |
| 2 | 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 |
| 3 | Concordance of non-invasive mechanical and serum tests for liver fibrosis evaluation in chronic hepatitis C显示文摘AIM To determine the sensitivity and specificity of liver stiffness measurement(LSM) and serum markers(SM) for liver fibrosis evaluation in chronic hepatitis C.METHODS Between 2012 and 2014,81 consecutive hepatitis C virus(HCV) patients had METAVIR score from liver biopsy compared with concurrent results from LSM [transient elastography(TE) [FibroS can~/ARFI technology(Virtual Touch~)] and SM [FIB-4/aspartate aminotransferase-toplatelet ratio index(APRI)].The diagnostic performance of these tests was assessed using receiver operating characteristic curves.The optimal cut-off levels of each test were chosen to define fibrosis stages F ≥ 2,F ≥ 3 and F = 4.The Kappa index set the concordance analysis.RESULTS Fifty point six percent were female and the median age was 51 years(30-78).Fifty-six patients(70%) weretreatment-na?ve.The optimal cut-off values for predicting F ≥ 2 stage fibrosis assessed by TE were 6.6 kP a,for acoustic radiation force impulse(ARFI) 1.22 m/s,for APRI 0.75 and for FIB-4 1.47.For F ≥ 3 TE was 8.9 kP a,ARFI was 1.48 m/s,APRI was 0.75,and FIB-4 was 2.For F = 4,TE was 12.2 kP a,ARFI was 1.77 m/s,APRI was 1.46,and FIB-4 was 3.91.The APRI could not distinguish between F2 and F3,P = 0.92.The negative predictive value for F = 4 for TE and ARFI was 100%.Kappa index values for F ≥ 3 METAVIR score for TE,ARFI and FIB-4 were 0.687,0.606 and 0.654,respectively.This demonstrates strong concordance between all three screening methods,and moderate to strong concordance between them and APRI(Kappa index = 0.507).CONCLUSION Given the costs and accessibility of LSM methods,and the similarity with the outcomes of SM,we suggest that FIB-4 as well as TE and ARFI may be useful indicators of the degree of liver fibrosis.This is of particular importance to developing countries. | Denise C Paranaguá-Vezozzo Adriana Andrade Daniel F C Mazo Vinicius Nunes Ana L Guedes Taisa G Ragazzo Renata Moutinho Lucas S Nacif Suzane K Ono Venancio A F Alves Flair J Carrilho | 2017 | World Journal of Hepatology2017，9，8： | 7 |
| 4 | Menopause and cognitive impairment:A narrative review of current knowledge显示文摘A severe impairment of cognitive function characterizes dementia.Mild cognitive impairment represents a transition between normal cognition and dementia.The frequency of cognitive changes is higher in women than in men.Based on this fact,hormonal factors likely contribute to cognitive decline.In this sense,cognitive complaints are more common near menopause,a phase marked by a decrease in hormone levels,especially estrogen.Additionally,a tendency toward worsened cognitive performance has been reported in women during menopause.Vasomotor symptoms(hot flashes,sweating,and dizziness),vaginal dryness,irritability and forgetfulness are common and associated with a progressive decrease in ovarian function and a subsequent reduction in the serum estrogen concentration.Hormone therapy(HT),based on estrogen with or without progestogen,is the treatment of choice to relieve menopausal symptoms.The studies conducted to date have reported conflicting results regarding the effects of HT on cognition.This article reviews the main aspects of menopause and cognition,including the neuroprotective role of estrogen and the relationship between menopausal symptoms and cognitive function.We present and discuss the findings of the central observational and interventional studies on HT and cognition. | Délio Marques Conde Roberto Carmignani Verdade Ana L R Valadares Lucas F B Mella Adriana OrcesiPedro Lucia Costa-Paiva | 2021 | World Journal of Psychiatry2021，11，8： | 3 |

| 7 | 氮素改变辣椒初级代谢和薄壁组织厚度调控比叶面积研究显示文摘比叶面积(SLA)是影响植物光截获和光利用效率的关键性状,常常影响植物的生长和产量。SLA是解释不同植物在不同环境下生长差异的一个关键性状。光照和氮素供应都是决定SLA的重要因素。为了更好地了解辐照度和氮素对辣椒(Capsicum chinense)SLA的影响,研究对两个中国辣椒商品种(Biquinho和Habanero)的初级代谢产物和形态特征进行了分析。两种基因型辣椒的SLA随着遮阴而增加,但随氮供应量的增加而下降;在氮素供应由缺乏到充足的范围内Habanero品种的SLA表现稳定。相关分析表明,高氮供应导致SLA降低是因为氨基酸、蛋白质和淀粉含量的调节,从而影响叶片密度。此外,在中度缺氮到充足供氮范围内,两种基因型辣椒的SLA表现出响应差异,Biquinho和Habanero分别在栅栏和海绵状薄壁组织上表现出差异。总之,结果表明,SLA对氮供应的反应是由某些代谢物含量和依赖于基因型的影响叶片厚度及密度的薄壁组织变化平衡调节的。 | Lucas de ávila Silva Rebeca P.Omena-Garcia Jorge A.Condori-Apfata Paulo Mafra de Almeida Costa Natália Machado Silva Fábio M.Da Matta Agustin Zsogon Wagner L.Araújo Edgard A.de Toledo Picoli Ronan Sulpice Adriano Nunes-Nesi 沈凌峰 吉雪花(译) | 2021 | 辣椒杂志2021，，3： | 2 |
