1Managements of recurrent hepatocellular carcinoma after liver transplantation: A systematic review显示文摘AIM: To investigate the efficacy(survival) and safety of treatments for recurrent hepatocellular carcinoma(HCC) in liver transplantation(LT) patients.METHODS: Literature search was performed on available online databases without a time limit until January 2015. Clinical studies describing survival after HCC recurrence in LT patients were retrieved for a fulltext evaluation. A total of 61 studies were selected: 13 case reports, 41 retrospective case series, and 7 retrospective comparative studies.RESULTS: Based on all included studies, the mean HCC recurrence rate was 16% of all LTs for HCC. A total of 1021 LT patients experienced HCC recurrence. The median time from LT to HCC recurrence was 13 mo(range 2-132 mo). The majority of patients(67%) presented with HCC extra-hepatic recurrences, involving lung, bone, adrenal gland, peritoneal lymph nodes, and rarely the brain. Overall survival after HCC recurrence was 12.97 mo. Surgical resection of localized HCC recurrence and Sorafenib for controlling systemic spread of HCC recurrence were associated with the higher survival rates(42 and 18 mo, res-pectively). However, Sorafenib, especially when combined with m TOR, was frequently associated with severe side effects that required dose reduction or discontinuation CONCLUSION: Management of recurrent HCC in LT patients is challenging and associated with poor prognosis independently of the type of treatment.Nicola de'Angelis Filippo Landi Maria Clotilde Carra Daniel Azoulay 2015World Journal of Gastroenterology2015,21,39:42
2Short-term clinical outcomes of laparoscopic vs open rectal excision for rectal cancer: A systematic review and metaanalysis显示文摘AIM To review evidence on the short-term clinical outcomes of laparoscopic(LRR) vs open rectal resection(ORR) for rectal cancer.METHODS A systematic literature search was performed using Cochrane Central Register, MEDLINE, EMBASE, Scopus, Open Grey and Clinical Trials.gov register for randomized clinical trials(RCTs) comparing LRR vs ORR for rectal cancer and reporting short-term clinical outcomes. Articles published in English from January 1, 1995 to June, 30 2016 that met the selection criteria were retrieved and reviewed. The Preferred Reporting Items for Systematic reviews and Meta-Analysis(PRISMA) statements checklist for reporting a systematic review was followed. Random-effect models were used to estimate mean differences and risk ratios. The robustness and heterogeneity of the results were explored by performing sensitivity analyses. The pooledeffect was considered significant when P < 0.05.RESULTS Overall, 14 RCTs were included. No differences were found in postoperative mortality(P = 0.19) and morbidity(P = 0.75) rates. The mean operative time was 36.67 min longer(95%CI: 27.22-46.11, P < 0.00001), the mean estimated blood loss was 88.80 ml lower(95%CI:-117.25 to-60.34, P < 0.00001), and the mean incision length was 11.17 cm smaller(95%CI:-13.88 to-8.47, P < 0.00001) for LRR than ORR. These results were confirmed by sensitivity analyses that focused on the four major RCTs. The mean length of hospital stay was 1.71 d shorter(95%CI:-2.84 to-0.58, P < 0.003) for LRR than ORR. Similarly, bowel recovery(i.e., day of the first bowel movement) was 0.68 d shorter(95%CI:-1.00 to-0.36, P < 0.00001) for LRR. The sensitivity analysis did not confirm a significant difference between LRR and ORR for these latter two parameters. The overall quality of the evidence was rated as high. CONCLUSION LRR is associated with lesser blood loss, smaller incision length, and longer operative times compared to ORR. No differences are observed for postoperative morbidity and mortality.Aleix Martínez-Pérez Maria Clotilde Carra Francesco Brunetti Nicola de'Angelis 2017World Journal of Gastroenterology2017,23,44:33
3Foveal avascular zone area and parafoveal vessel density measurements in different stages of diabetic retinopathy by optical coherence tomography angiography显示文摘AIM:To investigate foveal avascular zone(FAZ) and parafoveal vessel densities(PRVD) by means of optical coherence tomography angiography(OCTA) in diabetic patients with or without diabetic retinopathy(DR) and to assess the reproducibility of FAZ and PRVD measurements.METHODS:Sixty diabetic patients(60 eyes) with different stage of DR(graded according to the International Clinical Severity Scale for DR) and 20 healthy subjects underwent FAZ area and PRVD measurements using OCTA by two experienced examiners.FAZ area in all patients was also assessed using fluorescein angiography(FA).RESULTS:In subject with proliferative DR and with moderate-severe non proliferative DR,FAZ area was significantly increased compared to healthy controls(P=0.025 and P=0.050 respectively measured with OCTA and P=0.025 and P=0.048 respectively measured with FA).OCTA showed significantly less inter-observer variability compared to FA.Concordance correlation coefficient(CCC) for FAZ area measurements was 0.829(95%CI:0.736-0.891) P<0.001 with FA and 1.000(95%CI:0.999-1.000) P<0.001 with OCTA.CCC was 0.834(95%CI:0.746-0.893) P<0.001 and 0.890(95%CI:0.828-0.930) P<0.001 for parafoveal superficial and deep vessel density measurements,respectively.CONCLUSION:OCTA shows progressive increase of FAZ area and reduction of PRVD in both superficial and deep plexus at increasing DR severity.FAZ area and PRVD measurements using OCTA are highly reproducible.Rodolfo Mastropasqua Lisa Toto Alessandra Mastropasqua Raffaella Aloia Chiara De Nicola Peter A Mattei Guido Di Marzio Marta Di Nicola Luca Di Antonio 2017International Journal of Ophthalmology(English edition)2017,10,10:26
4Esophageal motility abnormalities in gastroesophageal reflux disease显示文摘Esophageal motility abnormalities are among the main factors implicated in the pathogenesis of gastroesophageal reflux disease. The recent introduction in clinical and research practice of novel esophageal testing has markedly improved our understanding of the mechanisms contributing to the development of gastroesophageal reflux disease, allowing a better management of patients with this disorder. In this context, the present article intends to provide an overview of the current literature about esophageal motility dysfunctions in patients with gastroesophageal reflux disease. Esophageal manometry, by recording intraluminal pressure, represents the gold standard to diagnose esophagealmotility abnormalities. In particular, using novel techniques, such as high resolution manometry with or without concurrent intraluminal impedance monitoring, transient lower esophageal sphincter (LES) relaxations, hypotensive LES, ineffective esophageal peristalsis and bolus transit abnormalities have been better defined and strongly implicated in gastroesophageal reflux disease development. Overall, recent findings suggest that esophageal motility abnormalities are increasingly prevalent with increasing severity of reflux disease, from nonerosive reflux disease to erosive reflux disease and Barrett's esophagus. Characterizing esophageal dysmotility among different subgroups of patients with reflux disease may represent a fundamental approach to properly diagnose these patients and, thus, to set up the best therapeutic management. Currently, surgery represents the only reliable way to restore the esophagogastric junction integrity and to reduce transient LES relaxations that are considered to be the predominant mechanism by which gastric contents can enter the esophagus. On that ground, more in depth future studies assessing the pathogenetic role of dysmotility in patients with reflux disease are warranted.Irene Martinucci Nicola de Bortoli Maria Giacchino Giorgia Bodini Elisa Marabotto Santino Marchi Vincenzo Savarino Edoardo Savarino 2014World Journal of Gastrointestinal Pharmacology and Therapeutics2014,5,2:24
5Pancreatic metastases from renal cell carcinoma:The state of the art显示文摘Pancreatic metastases are rare,with a reported incidence varying from 1.6%to 11%in autopsy studies of patients with advanced malignancy.In clinical series,the frequency of pancreatic metastases ranges from 2%to 5%of all pancreatic malignant tumors.However,the pancreas is an elective site for metastases from carcinoma of the kidney and this peculiarity has been reported by several studies.The epidemiology,clinical presentation,and treatment of pancreatic metastases from renal cell carcinoma are known from singleinstitution case reports and literature reviews.Thereis currently very limited experience with the surgical resection of isolated pancreatic metastasis,and the role of surgery in the management of these patients has not been clearly defined.In fact,for many years pancreatic resections were associated with high rates of morbidity and mortality,and metastatic disease to the pancreas was considered to be a terminal-stage condition.More recently,a significant reduction in the operative risk following major pancreatic surgery has been demonstrated,thus extending the indication for these operations to patients with metastatic disease.Roberto Ballarin Mario Spaggiari Nicola Cautero Nicola De Ruvo Roberto Montalti Cristina Longo Anna Pecchi Patrizia Giacobazzi Giuseppina De Marco Giuseppe D’Amico Giorgio Enrico Gerunda Fabrizio Di Benedetto 2011World Journal of Gastroenterology2011,17,43:21
6Evaluation of latent links between irritable bowel syndrome and sleep quality显示文摘AIM:To examine the links between quality of sleep and the severity of intestinal symptoms in irritable bow-el syndrome(IBS).METHODS:One hundred and forty-two outpatients(110female,32 male)who met the Rome Ⅲ criteria for IBS with no psychiatric comorbidity were consecutively en-rolled in this study.Data on age,body mass index(BMI),and a set of life-habit variables were recorded,and IBS symptoms and sleep quality were evaluated using the questionnaires IBS Symptom Severity Score(IBS-SSS)and Pittsburgh Sleep Quality Index(PSQI).The associa-tion between severity of IBS and sleep disturbances was evaluated by comparing the global IBS-SSS and PSQI score(Pearson's correlation and Fisher's exact test)and then analyzing the individual items of the IBS-SSS and PSQI questionnaires by a unitary bowel-sleep model based on item response theory(IRT).RESULTS:IBS-SSS ranged from mild to severe(120-470).The global PSQI score ranged from 1 to 17(median 5),and 60 patients were found to be poor sleepers(PSQI>5).The correlation between the global IBS-SSS and PSQI score indicated a weak association(r=0.2 and 95% CI:-0.03 to 0.35,P<0.05),which becomes stronger using our unitary model.Indeed,the IBS and sleep disturbances severities,estimated as latent variables,resulted significantly high intra-subject cor-relation(posterior mean of r=0.45 and 95% CI:0.17 to 0.70,P<0.05).Moreover,the correlations between patient features(age,sex,BMI,daily coffee and alcohol intake)and IBS and sleep disturbances were also ana-lyzed through our unitary model.Age was a signif icant regressor,with patients≤50 years old showing more severe bowel disturbances(posterior mean=-0.38,P<0.05)and less severe sleep disturbances(posterior mean=0.49,P<0.05)than older patients.Higher daily coffee intake was correlated with a lower sever-ity of bowel disturbances(posterior mean=-0.31,P<0.05).Sex(female)and daily alcohol intake(modest)were correlated with less severe sleep disturbances.CONCLUSION:The unitary bowel-sleep model based on IRT revealed a strong positive correlation between the severity of IBS symptoms and sleep disturbances.Massimo Bellini Angelo Gemignani Dario Gambaccini Simona Toti Danilo Menicucci Cristina Stasi Francesco Costa Maria Gloria Mumolo Angelo Ricchiuti Remo Bedini Nicola de Bortoli Santino Marchi 2011World Journal of Gastroenterology2011,17,46:17
7Diet and functional dyspepsia: Clinical correlates and therapeutic perspectives显示文摘Hypervigilance and symptoms anticipation,visceral hypersensitivity and gastroduodenal sensorimotor abnormalities account for the varied clinical presentation of functional dyspepsia(FD)patients.Many patients recognize meals as the main triggering factor;thus,dietary manipulations often represent the first-line management strategy in this cohort of patients.Nonetheless,scarce quality evidence has been produced regarding the relationship between specific foods and/or macronutrients and the onset of FD symptoms,resulting in nonstandardized nutritional approaches.Most dietary advises are indeed empirical and often lead to exclusion diets,reinforcing in patients the perception of“being intolerant”to food and self-perpetuating some of the very mechanisms underlying dyspepsia physiopathology(i.e.,hypervigilance and symptom anticipation).Clinicians are often uncertain regarding the contribution of specific foods to dyspepsia physiopathology and dedicated professionals(i.e.,dietitians)are only available in tertiary referral settings.This in turn,can result in nutritionally unbalanced diets and could even encourage restrictive eating behaviors in severe dyspepsia.In this review,we aim at evaluating the relationship between dietary habits,macronutrients and specific foods in determining FD symptoms.We will provide an overview of the evidence-based nutritional approach that should be pursued in these patients,providing clinicians with a valuable tool in standardizing nutritional advises and discouraging patients from engaging into indiscriminate food exclusions.Marcella Pesce Martina Cargiolli Sara Cassarano Barbara Polese Barbara De Conno Laura Aurino Nicola Mancino Giovanni Sarnelli 2020World Journal of Gastroenterology2020,26,5:14
8Innovative surgical approaches for hepatocellular carcinoma显示文摘Hepatocellular carcinoma(HCC)is the sixth most common cancer worldwide,with an increasing diffusion in Europe and the United States.The management of such a cancer is continuously progressing and the objective of this paper is to evaluate innovation in the surgical treatment of HCC.In this review,we will analyze the modern concept of preoperative management,the role of laparoscopic and robotic surgery,the intraoperative use of three dimensional models and augmented reality,as well as the potential application of fluorescence.Riccardo Memeo Nicola de’Angelis Vito de Blasi Zineb Cherkaoui Oronzo Brunetti Vito Longo Tullio Piardi Daniele Sommacale Jacques Marescaux Didier Mutter Patrick Pessaux 2016World Journal of Hepatology2016,8,13:13
9The enhanced X-ray Timing and Polarimetry mission—eXTP显示文摘In this paper we present the enhanced X-ray Timing and Polarimetry mission—eXTP. eXTP is a space science mission designed to study fundamental physics under extreme conditions of density, gravity and magnetism. The mission aims at determining the equation of state of matter at supra-nuclear density, measuring effects of QED, and understanding the dynamics of matter in strong-field gravity. In addition to investigating fundamental physics, eXTP will be a very powerful observatory for astrophysics that will provide observations of unprecedented quality on a variety of galactic and extragalactic objects. In particular, its wide field monitoring capabilities will be highly instrumental to detect the electro-magnetic counterparts of gravitational wave sources.The paper provides a detailed description of:(1) the technological and technical aspects, and the expected performance of the instruments of the scientific payload;(2) the elements and functions of the mission, from the spacecraft to the ground segment.ShuangNan Zhang Andrea Santangelo Marco Feroci YuPeng Xu FangJun Lu Yong Chen Hua Feng Shu Zhang Sφren Brandt Margarita Hernanz Luca Baldini Enrico Bozzo Riccardo Campana Alessandra De Rosa YongWei Dong Yuri Evangelista Vladimir Karas Norbert Meidinger Aline Meuris Kirpal Nandra Teng Pan Giovanni Pareschi Piotr Orleanski QiuShi Huang Stephane Schanne Giorgia Sironi Daniele Spiga Jiri Svoboda Gianpiero Tagliaferri Christoph Tenzer Andrea Vacchi Silvia Zane Dave Walton ZhanShan Wang Berend Winter Xin Wu Jean J.M.in't Zand Mahdi Ahangarianabhari Giovanni Ambrosi Filippo Ambrosino Marco Barbera Stefano Basso Jörg Bayer Ronaldo Bellazzini Pierluigi Bellutti Bruna Bertucci Giuseppe Bertuccio Giacomo Borghi XueLei Cao Franck Cadoux Francesco Ceraudo TianXiang Chen Yu Peng Chen Jerome Chevenez Marta Civitani Wei Cui WeiWei Cui Thomas Dauser Ettore Del Monte Sergio Di Cosimo Sebastian Diebold Victor Doroshenko Michal Dovciak YuanYuan Du Lorenzo Ducci QingMei Fan Yannick Favre Fabio Fuschino JoséLuis Ga'lvez Min Gao MingYu Ge Olivier Gevin Marco Grassi QuanYing Gu YuDong Gu DaWei Han Bin Hong Wei Hu Long Ji ShuMei Jia WeiChun Jiang Thomas Kennedy Ingo Kreykenbohm Irfan Kuvvetli Claudio Labanti Luca Latronico Gang Li MaoShun Li Xian Li Wei Li ZhengWei Li Olivier Limousin HongWei Liu XiaoJing Liu Bo Lu Tao Luo Daniele Macera Piero Malcovati Adrian Martindale Malgorzata Michalska Bin Meng Massimo Minuti Alfredo Morbidini Fabio Muleri Stephane Paltani Emanuele Perinati Antonino Picciotto Claudio Piemonte JinLu Qu Alexandre Rachevski Irina Rashevskaya Jerome Rodriguez Thomas Schanz ZhengXiang Shen LiZhi Sheng JiangBo Song LiMing Song Carmelo Sgro Liang Sun Ying Tan Phil Uttley Bo Wang DianLong Wang GuoFeng Wang Juan Wang LangPing Wang YuSa Wang Anna L.Watts XiangYang Wen Jörn Wilms ShaoLin Xiong JiaWei Yang Sheng Yang YanJi Yang Nian Yu WenDa Zhang Gianluigi Zampa Nicola Zampa Andrzej A.Zdziarski AiMei Zhang ChengMo Zhang Fan Zhang Long Zhang Tong Zhang Yi Zhang XiaoLi Zhang ZiLiang Zhang BaoSheng Zhao ShiJie Zheng Yu Peng Zhou Nicola Zorzi J.Frans Zwart 2019Science China(Physics,Mechanics & Astronomy)2019,62,2:11
10How many cases of laryngopharyngeal reflux suspected by laryngoscopy are gastroesophageal reflux disease-related?显示文摘AIM:To investigate the prevalence of gastroesophageal reflux disease(GERD) in patients with a laryngoscopic diagnosis of laryngopharyngeal reflux(LPR).METHODS:Between May 2011 and October 2011,41 consecutive patients with laryngopharyngeal symptoms(LPS) and laryngoscopic diagnosis of LPR were empirically treated with proton pump inhibitors(PPIs) for at least 8 wk,and the therapeutic outcome was assessed through validated questionnaires(GERD impact scale,GIS;visual analogue scale,VAS).LPR diagnosis was performed by ear,nose and throat specialists using the reflux finding score(RFS) and reflux symptom index(RSI).After a 16-d wash-out from PPIs,all patients underwent an upper endoscopy,stationary esophageal manometry,24-h multichannel intraluminal impedance and pH(MII-pH) esophageal monitoring.A positive correlation between LPR diagnosis and GERD was supposed based on the presence of esophagitis(ERD),pathological acid exposure time(AET) in the absence of esophageal erosions(NERD),and a positive correlation between symptoms and refluxes(hypersensitive esophagus,HE).RESULTS:The male/female ratio was 0.52(14/27),the mean age ± SD was 51.5 ± 12.7 years,and the mean body mass index was 25.7 ± 3.4 kg/m 2.All subjects reported one or more LPS.Twenty-five out of 41 patients also had typical GERD symptoms(heartburn and/or regurgitation).The most frequent laryngoscopic findings were posterior laryngeal hyperemia(38/41),linear indentation in the medial edge of the vocal fold(31/41),vocal fold nodules(6/41) and diffuse infraglottic oedema(25/41).The GIS analysis showed that 10/41 patients reported symptom relief with PPI therapy(P < 0.05);conversely,23/41 did not report any clinical improvement.At the same time,the VAS analysis showed a significant reduction in typical GERD symptoms after PPI therapy(P < 0.001).A significant reduction in LPS symptoms.On the other hand,such result was not recorded for LPS.Esophagitis was detected in 2/41 patients,and ineffective esophageal motility was found in 3/41 patients.The MII-pH analysis showed an abnormal AET in 5/41 patients(2 ERD and 3 NERD);11/41 patients had a normal AET and a positive association between symptoms and refluxes(HE),and 25/41 patients had a normal AET and a negative association between symptoms and refluxes(no GERD patients).It is noteworthy that HE patients had a positive association with typical GERD-related symptoms.Gas refluxes were found more frequently in patients with globus(29.7 ± 3.6) and hoarseness(21.5 ± 7.4) than in patients with heartburn or regurgitation(7.8 ± 6.2).Gas refluxes were positively associated with extraesophageal symptoms(P < 0.05).Overall,no differences were found among the three groups of patients in terms of the frequency of laryngeal signs.The proximal reflux was abnormal in patients with ERD/NERD only.The differences observed by means of MII-pH analysis among the three subgroups of patients(ERD/NERD,HE,no GERD) were not demonstrated with the RSI and RFS.Moreover,only the number of gas refluxes was found to have a significant association with the RFS(P = 0.028 andP = 0.026,nominal and numerical correlation,respectively).CONCLUSION:MII-pH analysis confirmed GERD diagnosis in less than 40% of patients with previous diagnosis of LPR,most likely because of the low specificity of the laryngoscopic findings.Nicola de Bortoli Andrea Nacci Edoardo Savarino Irene Martinucci Massimo Bellini Bruno Fattori Linda Ceccarelli Francesco Costa Maria Gloria Mumolo Angelo Ricchiuti Vincenzo Savarino Stefano Berrettini Santino Marchi 2012World Journal of Gastroenterology2012,18,32:11
11Epstein-Barr病毒相关疾病的IgG/Z抗体检测显示文摘血清中Epstein-Barr病毒(EBV)的IgG/Z抗体对鼻咽癌和传染性单核细胞增多症是较特异的,其阳性率分别为85.7%和84%。50%的伯基特淋巴瘤病人亦有IgG/Z抗体。正常人则没有,但有IgG/VCA等抗体,表明IgG/Z抗体在初次感染后是容易消失的。Z抗原与EBV复制相关,故IgG/Z抗体对鼻咽癌不仅有诊断意义,还可能有预后的意义。曾毅 Jean-claude Nicolas Guy Schwaab Guy de The Bernard Clausse Thomas Tursz Irene Joab 1992病毒学报1992,8,3:11
12More anxious than depressed:prevalence and correlates in a 15-nation study of anxiety disorders in people with type 2 diabetes mellitus显示文摘Background Anxiety disorder, one of the highly disabling, prevalent and common mental disorders, is known to be more prevalent in persons with type 2 diabetes mellitus (T2DM) than the general population, and the comorbid presence of anxiety disorders is known to have an impact on the diabetes outcome and the quality of life. However, the information on the type of anxiety disorder and its prevalence in persons with T2DM is limited. Aims To assess the prevalence and correlates of anxiety disorder in people with type 2 diabetes in different countries. Methods People aged 18-65 years with diabetes and treated in outpatient settings were recruited in 15 countries and underwent a psychiatric interview with the Mini-International Neuropsychiatric Interview. Demographic and medical record data were collected. Results A total of 3170 people with type 2 diabetes (56.2% women;with mean (SD) duration of diabetes 10.01 (7.0) years) participated. The overall prevalence of anxiety disorders in type 2 diabetic persons was 18%;however, 2.8% of the study population had more than one type of anxiety disorder. The most prevalent anxiety disorders were generalised anxiety disorder (8.1%) and panic disorder (5.1%). Female gender, presence of diabetic complications, longer duration of diabetes and poorer glycaemic control (HbA1c levels) were significantly associated with comorbid anxiety disorder. A higher prevalence of anxiety disorders was observed in Ukraine, Saudi Arabia and Argentina with a lower prevalence in Bangladesh and India. Conclusions Our international study shows that people with type 2 diabetes have a high prevalence of anxiety disorders, especially women, those with diabetic complications, those with a longer duration of diabetes and poorer glycaemic control. Early identification and appropriate timely care of psychiatric problems of people with type 2 diabetes is warranted.Santosh K Chaturvedi Shayanth Manche Gowda Helal Uddin Ahmed Fahad D Alosaimi Nicola Andreone Alexey Bobrov Viola Bulgari Giuseppe Carra Gianluca Castelnuovo Giovanni de Girolamo Tomasz Gondek Nikola Jovanovic Thummala Kamala Andrzej Ki Nebojsa Lalic Dusica Lecic-Tosevski Fareed Minhas Victoria Mutiso David Ndetei Golam Rabbani Suntibenchakul Somruk Sathyanarayana Srikanta Rizwan Taj Umberto Valentini Olivera Vukovic Wolfgang Wolwer Larry Cimino Arie Nouwen Cathy Lloyd Norman Sartorius 2019General Psychiatry2019,32,4:11
13Overlap of functional heartburn and gastroesophageal reflux disease with irritable bowel syndrome显示文摘Several studies indicate a significant degree of overlap between irritable bowel syndrome(IBS)and gastroesophageal reflux disease(GERD).Likewise,both functional heartburn(FH)and IBS are functional digestive disorders that may occur in the same patients.However,data establishing a solid link between FH and IBS are lacking,mainly because the clinical definition of FH has undergone substantial changes over the years.The available literature on the overlap between GERD or FH and IBS highlights considerable heterogeneity in terms of the criteria and diagnostic procedures used to assess heartburn and IBS.In particular,several epidemiological studies included patients with concomitant IBS and GERD without any attempt to distinguish FH(as defined by the RomeⅢcriteria)from GERD via pathophysiological investigations.Independent of these critical issues,there is preliminary evidence supporting a significantdegree of FH-IBS overlap.This underscores the need for studies based on updated diagnostic criteria and accurate pathophysiological classifications,particularly to distinguish FH from GERD.This distinction would represent an essential starting point to achieving a better understanding of pathophysiology in the subclasses of patients with GERD and FH and properly assessing the different degrees of overlap between IBS and the subcategories of heartburn.The present review article intends to appraise and critically discuss current evidence supporting a possible concomitance of GERD or FH with IBS in the same patients and to highlight the pathophysiological relationships between these disorders.Nicola de Bortoli Irene Martinucci Massimo Bellini Edoardo Savarino Vincenzo Savarino Corrado Blandizzi Santino Marchi 2013World Journal of Gastroenterology2013,19,35:9
14Esophageal testing: What we have so far显示文摘Gastroesophageal reflux disease(GERD) is a common disorder of the gastrointestinal tract. In the last few decades, new technologies have evolved and have been applied to the functional study of the esophagus, allowing for the improvement of our knowledge of the pathophysiology of GERD. High-resolution manometry(HRM) permits greater understanding of the function of the esophagogastric junction and the risks associated with hiatal hernia. Moreover, HRM has been found to be more reproducible and sensitive than conventional water-perfused manometry to detect the presence of transient lower esophageal sphincter relaxation. Esophageal 24-h p H-metry with or without combined impedance is usually performed in patients with negative endoscopy and reflux symptoms who have a poor response to anti-reflux medical therapy to assess esophageal acid exposure and symptom-reflux correlations. In particular, esophageal 24-h impedance and p H monitoring can detect acid and non-acid reflux events. Endo FLIP is a recent technique poorly applied in clinical practice, although it provides a large amount of information about the esophagogastric junction. In the coming years, laryngopharyngeal symptoms could be evaluated with up and coming non-invasive or minimally invasive techniques, such as pepsin detection in saliva or pharyngeal p H-metry. Future studies are required of these techniques to evaluate their diagnostic accuracy and usefulness, although the available data are promising.Nicola de Bortoli Irene Martinucci Lorenzo Bertani Salvatore Russo Riccardo Franchi Manuele Furnari Salvatore Tolone Giorgia Bodini Valeria Bolognesi Massimo Bellini Vincenzo Savarino Santino Marchi Edoardo Vincenzo Savarino 2016World Journal of Gastrointestinal Pathophysiology2016,7,1:8
15Vitamin D and acute myocardial infarction显示文摘Vitamin D deficiency is a prevalent condition,cutting across all ethnicities and among all age groups,and occurring in about 30%-50% of the population. Besides vitamin D established role in calcium homeostasis,its deficiency is emerging as a new risk factor for coronary artery disease. Notably,clinical investigations have suggested that there is an association between hypovitaminosis D and acute myocardial infarction(AMI). Not only has it been linked to incident AMI,but also to increased morbidity and mortality in this clinical setting. Moreover,vitamin D deficiency seems to predispose to recurrent adverse cardiovascular events,as it is associated with post-infarction complications and cardiac remodeling in patients with AMI. Several mechanisms underlying the association between vitamin D and AMI risk can be involved. Despite these observational and mechanistic data,interventional trials with supplementation of vitamin D are controversial. In this review,we will discuss the evidence on the association between vitamin D deficiency and AMI,in terms of prevalence and prognostic impact,and the possible mechanisms mediating it. Further research in this direction is warranted and it is likely to open up new avenues for reducing the risk of AMI.Valentina Milazzo Monica De Metrio Nicola Cosentino Giancarlo Marenzi Elena Tremoli 2017World Journal of Cardiology2017,9,1:7
16大气二氧化氮与每日总死亡率、心血管和呼吸系统疾病死亡率的短期关联:398个城市的多中心分析显示文摘目的:采用统一的分析方案,评估全球多个国家/地区的二氧化氮(NO_(2))与总死亡率、心血管和呼吸系统疾病死亡率之间的短期关联。研究设计:采用两阶段的时间序列分析方法、过度离散的广义线性模型和多水平meta分析。研究地点:22个低到高收入国家/地区的398个城市。主要结局指标:1973—2018年逐日总死亡人数(6280万人)、心血管疾病死亡人数(1970万人)和呼吸系统疾病死亡人数(550万人)。结果:平均而言,NO_(2)浓度在滞后1天(前1天)每增加10μg/m^(3),会导致总死亡率、心血管和呼吸系统疾病死亡率分别增加0.46%(95%可信区间0.36%~0.57%)、0.37%(0.22%~0.51%)、0.47%(0.21%~0.72%)。在对共污染物(PM_(10)、PM_(2.5)、臭氧、二氧化硫和一氧化碳)进行调整后,这些关联仍然很稳定。所有3种死因的暴露-反应曲线几乎是线性的,没有明显的阈值。在398个城市中,可归因于高过假定零水平的NO_(2)浓度造成的死亡比例为1.23%(95%可信区间0.96%~1.51%)。结论:这项多中心研究提供了关于NO_(2)短期暴露与总死亡率、心血管和呼吸系统死亡风险之间的独立和线性关联的关键证据,说明通过加强NO_(2)的控制和监管限制标准,可获得人群水平的健康收益。孟夏 刘聪(校) 陈仁杰 郑湃(译) 阚海东(校) Francesco Sera Ana Vicedo-Cabrera Ai Milojevic Maria Guo Yuming Tong Shilu Micheline de Sousa Zanotti Stagliorio Coelh Paulo Hilario Nascimento Saldiva Eric Lavigne Patricia Matus Correa Nicolas Valdes Ortega Samuel Osorio Garcia Jan Kysely Ales Urban Hans Orru Marek Maasikmets Jouni J K Jaakkola Niilo Ryti Veronika Huber Alexandra Schneider Klea Katsouyanni Antonis Analitis Masahiro Hashizume Yasushi Honda Chris Fook Sheng Ng Baltazar Nunes João Paulo Teixeira Iulian Horia Holobaca Simona Fratianni Ho Kim Aurelio Tobias Carmeníniguez Bertil Forsberg ChristoferÅström Martina S Ragettli Yue-Liang Leon Guo Shih-Chun Pan Shanshan Li Michelle L Bell Antonella Zanobetti Joel Schwartz Tangchun Wu Antonio Gasparrini 2021英国医学杂志中文版2021,24,8:7
17Silicon and silicon nitride photonic circuits for spectroscopic sensing on-a-chip [Invited]显示文摘There is a rapidly growing demand to use silicon and silicon nitride(Si3N4) integrated photonics for sensing applications, ranging from refractive index to spectroscopic sensing. By making use of advanced CMOS technology,complex miniaturized circuits can be easily realized on a large scale and at a low cost covering visible to mid-IR wavelengths. In this paper we present our recent work on the development of silicon and Si3N4-based photonic integrated circuits for various spectroscopic sensing applications. We report our findings on waveguide-based absorption, and Raman and surface enhanced Raman spectroscopy. Finally we report on-chip spectrometers and on-chip broadband light sources covering very near-IR to mid-IR wavelengths to realize fully integrated spectroscopic systems on a chip.Ananth Z.Subramanian Eva Ryckeboer Ashim Dhakal Frédéric Peyskens Aditya Malik Bart Kuyken Haolan Zhao Shibnath Pathak Alfonso Ruocco Andreas De Groote Pieter Wuytens Daan Martens Francois Leo Weiqiang Xie Utsav Deepak Dave Muhammad Muneeb Pol Van Dorpe Joris Van Campenhout Wim Bogaerts Peter Bienstman Nicolas Le Thomas Dries Van Thourhout Zeger Hens Gunther Roelkens Roel Baets 2015Photonics Research2015,3,5:7
18Navigated liver surgery:State of the art and future perspectives显示文摘Background:In recent years,the development of digital imaging technology has had a significant influence in liver surgery.The ability to obtain a 3-dimensional(3D)visualization of the liver anatomy has provided surgery with virtual reality of simulation 3D computer models,3D printing models and more recently holograms and augmented reality(when virtual reality knowledge is superimposed onto reality).In addition,the utilization of real-time fluorescent imaging techniques based on indocyanine green(ICG)uptake allows clinicians to precisely delineate the liver anatomy and/or tumors within the parenchyma,applying the knowledge obtained preoperatively through digital imaging.The combination of both has transformed the abstract thinking until now based on 2D imaging into a 3D preoperative conception(virtual reality),enhanced with real-time visualization of the fluorescent liver structures,effectively facilitating intraoperative navigated liver surgery(augmented reality).Data sources:A literature search was performed from inception until January 2021 in MEDLINE(Pub Med),Embase,Cochrane library and database for systematic reviews(CDSR),Google Scholar,and National Institute for Health and Clinical Excellence(NICE)databases.Results:Fifty-one pertinent articles were retrieved and included.The different types of digital imaging technologies and the real-time navigated liver surgery were estimated and compared.Conclusions:ICG fluorescent imaging techniques can contribute essentially to the real-time definition of liver segments;as a result,precise hepatic resection can be guided by the presence of fluorescence.Furthermore,3D models can help essentially to further advancing of precision in hepatic surgery by permitting estimation of liver volume and functional liver remnant,delineation of resection lines along the liver segments and evaluation of tumor margins.In liver transplantation and especially in living donor liver transplantation(LDLT),3D printed models of the donor’s liver and models of the recipient’s hilar anatomy can contribute further to improving the results.In particular,pediatric LDLT abdominal cavity models can help to manage the largest challenge of this procedure,namely large-for-size syndrome.Paschalis Gavriilidis Bjørn Edwin Egidijus Pelanis Ernest Hidalgo Nicola de’Angelis Riccardo Memeo Luca Aldrighetti Robert P Sutcliffe 2022Hepatobiliary & Pancreatic Diseases International2022,21,3:6
19IL-6对小鼠(B-杂交瘤)7TD1细胞凋亡的调控作用显示文摘小鼠B—杂交瘤7TD1细胞的生长依赖于IL—6的存在。本研究对有或无IL-6条件下,对7TD1细胞的生物学行为加以分析。结果发现:1.细胞在缺乏IL—6时,生长停滞并出现细胞凋亡的典型特征;2.DNA核酸酶抑制剂ATA可有效防止因IL—6缺乏所致的凋亡;3.RNA合成抑制剂CHX能充分抑制IL—6对7TD1的生物效应,从而使细胞步入凋亡。本研究提示,IL—6通过抑制7TD1内部持续存在的细胞死亡程序来促进细胞存活和生长;而这种抑制作用需要新的蛋白质合成。刘佳 李宏 Marie-FranceHamou Nicolas de Tribolet 1995中华微生物学和免疫学杂志1995,15,6:6
