2Percutaneous endoscopic gastrostomy:Indications,technique,complications and management显示文摘Percutaneous endoscopic gastrostomy(PEG)is the preferred route of feeding and nutritional support in patients with a functional gastrointestinal system who require long-term enteral nutrition.Besides its wellknown advantages over parenteral nutrition,PEG offers superior access to the gastrointestinal system over surgical methods.Considering that nowadays PEG tube placement is one of the most common endoscopic procedures performed worldwide,knowing its indications and contraindications is of paramount importance in current medicine.PEG tubes are sometimes placed inappropriately in patients unable to tolerate adequate oral intake because of incorrect and unrealistic understanding of their indications and what they can accomplish.Broadly,the two main indications of PEG tube placement are enteral feeding and stomach decompression.On the other hand,distal enteral obstruction,severe uncorrectable coagulopathy and hemodynamic instability constitute the main absolute contraindications for PEG tube placement in hospitalized patients.Although generally considered to be a safe procedure,there is the potential for both minor and major complications.Awareness of these potential complications,as well as understanding routine aftercare of the catheter,can improve the quality of care for patients with a PEG tube.These complications can generally be classified into three major categories:endoscopic technical difficulties,PEG procedure-related complications and late complications associated with PEG tube use and wound care.In this review we describe a variety of minor and major tube-related complications as well as strategies for their management and avoidance.Different methods of percutaneous PEG tube placement into the stomach have been described in the literature with the'pull'technique being the most common method.In the last section of this review,the reader is presented with a brief discussion of these procedures,techniques and related issues.Despite the mentioned PEG tube placement complications,this procedure has gained worldwide popularity as a safe enteral access for nutrition in patients with a functional gastrointestinal system.Ata A Rahnemai-Azar Amir A Rahnemaiazar Rozhin Naghshizadian Amparo Kurtz Daniel T Farkas 2014World Journal of Gastroenterology2014,20,24:38
3WJD 5^(th) Anniversary Special Issues(2): Type 2 diabetes Type 2 diabetes and cardiovascular disease: Have all risk factors the same strength?显示文摘Diabetes mellitus is a chronic condition that occurs when the body cannot produce enough or effectively use of insulin.Compared with individuals without diabetes,patients with type 2 diabetes mellitus have a considerably higher risk of cardiovascular morbidity and mortality,and are disproportionately affected by cardiovascular disease.Most of this excess risk is it associated with an augmented prevalence of well-known risk factors such as hypertension,dyslipidaemia and obesity in these patients.However the improved cardiovascular disease in type 2 diabetes mellitus patients can not be attributed solely to the higher prevalence of traditional risk factors.Therefore other non-traditional risk factors may be important in people with type 2 diabetes mellitus.Cardiovascular disease is increased in type 2 diabetes mellitus subjects due to a complex combination of various traditional and non-traditional risk factors that have an important role to play in the beginning and the evolution of atherosclerosis over its long natural history from endothelial function to clinical events.Many of these risk factors could be common history for both di-abetes mellitus and cardiovascular disease,reinforcing the postulate that both disorders come independently from'common soil'.The objective of this review is to highlight the weight of traditional and non-traditional risk factors for cardiovascular disease in the setting of type 2 diabetes mellitus and discuss their position in the pathogenesis of the excess cardiovascular disease mortality and morbidity in these patients.Iciar Martín-Timón Cristina Sevillano-Collantes Amparo Segura-Galindo Francisco Javier del Caizo-Gómez 2014World Journal of Diabetes2014,5,4:32
4Non invasive blood flow measurement in cerebellum detects minimal hepatic encephalopathy earlier than psychometric tests显示文摘AIM: To assess whether non invasive blood flow measurement by arterial spin labeling in several brain regions detects minimal hepatic encephalopathy. METHODS: Blood flow(BF) was analyzed by arterial spin labeling(ASL) in different brain areas of 14 controls, 24 cirrhotic patients without and 16 cirrhotic patients with minimal hepatic encephalopathy(MHE). Images were collected using a 3 Tesla MR scanner(Achieva 3T-TX, Philips, Netherlands). Pulsed ASL was performed. Patients showing MHE were detected using the battery Psychometric Hepatic Encephalopathy Score(PHES) consisting of five tests. Different cognitive and motor functions were also assessed: alterations in selective attention were evaluated using the Stroop test. Patients and controls also performed visuo-motor and bimanual coordination tests. Several biochemical parameters were measured: serum pro-inflammatory interleukins(IL-6 and IL-18), 3-nitrotyrosine, cGMP and nitrates+nitrites in plasma, and blood ammonia. Bivariate correlations were evaluated.RESULTS: In patients with MHE, BF was increased in cerebellar hemisphere(P = 0.03) and vermis(P = 0.012) and reduced in occipital lobe(P = 0.017). BF in cerebellar hemisphere was also increased in patients without MHE(P = 0.02). Bimanual coordination was impaired in patients without MHE(P = 0.05) and much more in patients with MHE(P < 0.0001). Visuo-motor coordination was impaired only in patients with MHE(P < 0.0001). Attention was slightly affected in patients without MHE and more strongly in patients with MHE(P< 0.0001). BF in cerebellar hemisphere and vermis correlated with performance in most tests of PHES [(number connection tests A(NCT-A), B(NCT-B)and line tracing test] and in the congruent task of Stroop test. BF in frontal lobe correlated with NCT-A. Performance in bimanual and visuomotor coordination tests correlated only with BF in cerebellar hemisphere. BF in occipital lobe correlates with performance in the PHES battery and with CFF. BF in cerebellar hemisphere correlates with plasma cGMP and nitric oxide(NO) metabolites. BF in vermis cerebellar also correlates with NO metabolites and with 3-nitrotyrosine. IL-18 in plasma correlates with BF in thalamus and occipital lobe.CONCLUSION: Non invasive BF determination in cerebellum using ASL may detect MHE earlier than the PHES. Altered NO-cGMP pathway seems to be associated to altered BF in cerebellum.Vicente Felipo Amparo Urios Carla Giménez-Garzó Omar Cauli Maria-Jesús Andrés-Costa Olga González Miguel A Serra Javier Sánchez-González Roberto Aliaga Remedios Giner-Durán Vicente Belloch Carmina Montoliu 2014World Journal of Gastroenterology2014,20,33:12
5Rifaximin,but not growth factor 1,reduces brain edema in cirrhotic rats显示文摘AIM:To compare rifaximin and insulin-like growth factor(IGF)-1 treatment of hyperammonemia and brain edema in cirrhotic rats with portal occlusion.METHODS:Rats with CCl4-induced cirrhosis with ascites plus portal vein occlusion and controls were randomized into six groups:Cirrhosis;Cirrhosis + IGF-1;Cirrhosis + rifaximin;Controls;Controls + IGF-1;and Controls + rifaximin.An oral glutamine-challenge test was performed,and plasma and cerebral ammonia,glucose,bilirubin,transaminases,endotoxemia,brain water content and ileocecal cultures were measured and liver histology was assessed.RESULTS:Rifaximin treatment significantly reduced bacterial overgrowth and endotoxemia compared with cirrhosis groups,and improved some liver function parameters(bilirubin,alanine aminotransferase and aspartate aminotransferase).These effects were associated with a significant reduction in cerebral water content.Blood and cerebral ammonia levels,and area-underthe-curve values for oral glutamine-challenge tests were similar in rifaximin-treated cirrhotic rats and control group animals.By contrast,IGF-1 administration failed to improve most alterations observed in cirrhosis.CONCLUSION:By reducing gut bacterial overgrowth,only rifaximin was capable of normalizing plasma and brain ammonia and thereby abolishing low-grade brain edema,alterations associated with hepatic encephalopathy.Gemmaòdena Mireia Miquel Anna Serafín Amparo Galan Rosa Morillas Ramon Planas Ramon Bartolí 2012World Journal of Gastroenterology2012,18,17:6
6High prevalence of viable Mycobacterium avium subspecies paratuberculosis in Crohn's disease显示文摘AIM:To examine the detection rate of viable Mycobacterium avium subspecies paratuberculosis(MAP) in patients with inflammatory bowel disease [Crohn's disease(CD) and ulcerative colitis(UC)].METHODS:Thirty patients with CD(15 with at least one NOD2/CARD15 mutation),29 with UC,and 10 with no inflammatory bowel disease(IBD).were tested for MAP by polymerase chain reaction(specific IS900 fragment) and blood culture.RESULTS:MAP DNA was detected in all original blood samples and 8-wk blood cultures(CD,UC and non-IBD).Positive MAP DNA status was confirmed by dot blot assays.All 69 cultures were negative by acid-fast Ziehl-Neelsen staining.Viable MAP,in spheroplast form,was isolated from the 18-mo blood cultures of all 30 CD patients,one UC patient,and none of the non-IBD controls.No association was found between positive MAP cultures and use of immunosuppressive drugs or CDassociated single nucleotide polymorphisms.CONCLUSION:MAP is widely present in our area and MAP DNA can be recovered from the blood of CD,UC and non-IBD patients.However,MAP spheroplasts were only found in CD patients.Juan L Mendoza Amparo San-Pedro Esther Culebras Raquel Cíes Carlos Taxonera Raquel Lana Elena Urcelay Fernando de la Torre Juan J Picazo Manuel Díaz-Rubio 2010World Journal of Gastroenterology2010,16,36:5
7Clinical-pathological and molecular characterization of long-term survivors with advanced non-small cell lung cancer显示文摘Objective:Long-term survivors(LS)of non-small cell lung cancer(NSCLC)without driver alterations,displaying an overall survival(OS)of more than 3 years,comprise around 10%of cases in several series treated with chemotherapy.There are classical prognosis factors for these cases[stage,Eastern Cooperative Oncology Group(ECOG),etc.],but more data are required in the literature.In this multi-center study,we focused on LS of advanced NSCLC with OS above 36 months to perform a clinical-pathological and molecular characterization.Methods:In the first step,we conducted a clinical-pathological characterization of the patients.Afterwards,we carried out a genetic analysis by comparing LS to a sample of short-term survivors(SS)(with an OS less than 9 months).We initially used whole-genome RNA-seq to identify differentiating profiles of LS and SS,and later confirmed these with reverse transcription-polymerase chain reaction(RT-PCR)for the rest of the samples.Results:A total of 94 patients were included,who were mainly men,former smokers,having adenocarcinoma(AC)-type NSCLC with an ECOG of 0-1.We obtained an initial differential transcriptome expression,displaying 5 over-and 33 under-expressed genes involved in different pathways:namely,the secretin receptor,surfactant protein,trefoil factor 1(T FF1),serpin,Ca-channels,and Tolllike receptor(TLRs)families.Finally,RT-PCR analysis of 40(20 LS/20 SS)samples confirmed that four genes(surfactant proteins and SFTP)were significantly down-regulated in SS compared to LS by using an analysis of covariance(ANCOVA)model:SFTPA1(P=0.023),SFTPA2(P=0.027),SFTPB{P=0.02),and SFT PC(P=0.047).Conclusions:We present a sequential genetic analysis of a sample of NSCLCLS with no driver alterations,obtaining a differential RNA-seq/RT-PCR profile showing an abnormal expression of SF genes.Juan Moreno-Rubio Santiago Ponce Rosa Alvarez Maria Eugenia Olmedo Sandra Falagan Xabier Mielgo Fatima Navarro Patricia Cruz Luis Cabezon-Gutierrez Carlos Aguado Gonzalo Colmenarejo Marta Munoz-Fernandez de Leglaria Ana Belen Enguita Maria Cebollero Amparo Benito Isabel Alemany Carolina del Castillo Ricardo Ramos Ana Ramirez de Molina Enrique Casado Maria Sereno 2020Cancer Biology & Medicine2020,17,2:4
8Nutritional value of high fiber co-products from the copra,palm kernel,and rice industries in diets fed to pigs显示文摘High fiber co-products from the copra and palm kernel industries are by-products of the production of coconut oil and palm kernel oil. The co-products include copra meal, copra expellers, palm kernel meal, and palm kernel expellers. All 4 ingredients are very high in fiber and the energy value is relatively low when fed to pigs. The protein concentration is between 14 and 22 % and the protein has a low biological value and a very high Arg:Lys ratio. Digestibility of most amino acids is less than in soybean meal but close to that in corn. However, the digestibility of Lys is sometimes low due to Maillard reactions that are initiated due to overheating during drying.Copra and palm kernel ingredients contain 0.5 to 0.6 % P. Most of the P in palm kernel meal and palm kernel expellers is bound to phytate, but in copra products less than one third of the P is bound to phytate. The digestibility of P is, therefore, greater in copra meal and copra expellers than in palm kernel ingredients. Inclusion of copra meal should be less than 15 % in diets fed to weanling pigs and less than 25 % in diets for growing-finishing pigs. Palm kernel meal may be included by 15 % in diets for weanling pigs and 25 % in diets for growing and finishing pigs.Rice bran contains the pericarp and aleurone layers of brown rice that is removed before polished rice is produced.Rice bran contains approximately 25 % neutral detergent fiber and 25 to 30 % starch. Rice bran has a greater concentration of P than most other plant ingredients, but 75 to 90 % of the P is bound in phytate. Inclusion of microbial phytase in the diets is, therefore, necessary if rice bran is used. Rice bran may contain 15 to 24 % fat, but it may also have been defatted in which case the fat concentration is less than 5 %. Concentrations of digestible energy(DE) and metabolizable energy(ME) are slightly less in full fat rice bran than in corn, but defatted rice bran contains less than 75 % of the DE and ME in corn. The concentration of crude protein is 15 to 18 % in rice bran and the protein has a high biological value and most amino acids are well digested by pigs. Inclusion of rice bran in diets fed to pigs has yielded variable results and based on current research it is recommended that inclusion levels are less than 25 to 30 % in diets for growing-finishing pigs, and less than 20 % in diets for weanling pigs.However, there is a need for additional research to determine the inclusion rates that may be used for both full fat and defatted rice bran.Hans Henrik Stein Gloria Amparo Casas Jerubella Jerusalem Abelilla Yanhong Liu Rommel Casilda Sulabo 2016Journal of Animal Science and Biotechnology2016,7,2:3
9Regulation of mitochondrial function and endoplasmic reticulum stress by nitric oxide in pluripotent stem cells显示文摘Mitochondrial dysfunction and endoplasmic reticulum stress(ERS) are global processes that are interrelated and regulated by several stress factors. Nitric oxide(NO) is a multifunctional biomolecule with many varieties of physiological and pathological functions, such as the regulation of cytochrome c inhibition and activation of the immune response, ERS and DNA damage; these actions are dose-dependent. It has been reported that in embryonic stem cells, NO has a dual role, controlling differentiation, survival and pluripotency, but the molecular mechanisms by which it modulates these functions are not yet known. Low levels of NO maintain pluripotency and induce mitochondrial biogenesis. It is well established that NO disrupts the mitochondrial respiratory chain and causes changes in mitochondrial Ca^(2+) flux that induce ERS. Thus, at high concentrations, NO becomes a potential differentiation agent due to the relationship between ERS and the unfolded protein response in many differentiated cell lines. Nevertheless, many studies have demonstratedthe need for physiological levels of NO for a proper ERS response. In this review, we stress the importance of the relationships between NO levels, ERS and mitochondrial dysfunction that control stem cell fate as a new approach to possible cell therapy strategies.Estefania Caballano-Infantes José Terron-Bautista Amparo Beltrán-Povea Gladys M Cahuana Bernat Soria Hajji Nabil Francisco J Bedoya Juan R Tejedo 2017World Journal of Stem Cells2017,9,2:2
