METHODS:Colonic mucosal pinch biopsies from the descending part were obtained endoscopically from patients with active UC or CD, quiescent UC or CD, as well as healthy controls. Total RNA was isolated and miRNA expression assessed using the miRNA microarray Geniom Biochip miRNA Homo sapiens (Febit GmbH, Heidelberg, Germany). Data analysis was carried out by principal component analysis and projection to latent structure-discriminant analysis using the SIMCA-P+12 software package (Umetrics, Umea, Sweden). The microarray data were subsequently validated by quantitative real-time polymerase chain reaction (qPCR) performed on colonic tissue samples from active UC patients (n = 20), patients with quiescent UC (n = 19), and healthy controls (n = 20). The qPCR results were analyzed with Mann-WhitneyU test.In silico prediction analysis were performed to identify potential miRNA target genes and the predicted miRNA targets were then compared with all UC associated susceptibility genes reported in the literature. RESULTS:The colonic mucosal miRNA transcriptome differs significantly between UC and controls, UC and CD, as well as between UC patients with mucosal inflammation and those without. However, no clear differences in the transcriptome of patients with CD and controls were found. The miRNAs with the strongest differential power were identified (miR-20b, miR-99a, miR-203, miR-26b, and miR-98) and found to be upregulated more than a 10-fold in active UC as compared to quiescent UC, CD, and controls. Two miRNAs, miR-125b-1* and let-7e*, were up-regulated more than 5-fold in quiescent UC compared to active UC, CD, and controls. Four of the seven miRNAs (miR-20b, miR-98, miR-125b-1*, and let-7e*) were validated by qPCR and found to be specifically upregulated in patients with UC. Usingin silico analysis we found several predicted pro-inflammatory target genes involved in various pathways, such as mitogen-activated protein kinase and cytokine signaling, which are both key signaling pathways in UC.CONCLUSION:The present study provides the first evidence that miR-20b, miR-98, miR-125b-1*, and let7e* are deregulated in patients with UC. The level of these miRNAs may serve as new potential biomarkers for this chronic disease.展开更多

Until recently, research has focused on the study of protein regulators in inflammation to reveal the cellular and molecular networks in the pathogenesis of IBD. However, in the last few years, new and promising insights have been generated from studies describing an association between an altered expression of a specific class of non-coding RNAs, called microRNAs (miRs or miRNAs) and IBD. The short (approximately 22 nucleotides), endogenous, single-stranded RNAs are evolutionary conserved inanimals and plants, and regulate specific target mRNAs at the post-transcriptional level. MiRNAs are involved in several biological processes, including development, cell differentiation, proliferation and apoptosis. Furthermore, it is estimated that miRNAs may be responsible for regulating the expression of nearly one-third of the genes in the human genome. Thus, miRNA deregulation often results in an impaired cellular function, and a disturbance of downstream gene regulation and signaling cascades, suggesting their implication in disease etiology. Despite the identification of more than 1900 mature human miRNAs, very little is known about their biological functions and functional targets. Recent studies have identified dysregulated miRNAs in tissue samples of IBD patients and have demonstrated similar differences in circulating miRNAs in the serum of IBD patients. Thus, there is great promise that miRNAs will aid in the early diagnosis of IBD, and in the development of personalized therapies. Here, we provide a short review of the current state-of-the-art of miRNAs in IBD pathogenesis, diagnostics and therapeutics.展开更多

Discriminatory validity was assessed in a validation cohort including cirrhotic patients with(1) tense/severe;(2) moderate/mild; or(3) no ascites(controls). Patients also completed chronic liver disease questionnaire(CLDQ) and the Euro QoL 5-Dimensions 5-Level(EQ-5D-5L) questionnaire evaluating HRQL. The relation between scale scores was analysed using Spearman correlations. RESULTS The final CAS scale included 14 items. The equivalent reliability was high(Chronbach's alpha 0.88). The validation cohort included 103 patients(72% men, mean age 62.4 years). The mean scores for each question in the CAS scale were higher for patients with severe/tense ascites than for mild/moderate ascites and controls. Compared with controls(mean = 9.9 points), the total CAS scale score was higher for severe/tense ascites(mean = 23.8 points) as well as moderate/mild ascites(mean = 18.6 points)(P < 0.001 both groups). We found a strong correlation between the total CAS and CLDQ score(rho = 0.82, P < 0.001) and a moderate correlation between the CAS and the EQ-5D-5L score(0.67, P < 0.001). CONCLUSION The CAS is a valid tool, which reflects HRQOL in patients with ascites.展开更多

We report a case of an elderly woman who began taking Move Free Advanced for arthritis, which in addition to glucosamine and chondroitin, contained two herbal ingredients, Chinese skullcap and Black Catechu. Our patient presented with significant cholestasis and hepatitis which significantly improved after discontinuation of the supplement. Since neither the patient nor the treating physician recognized this supplement as a potential hepatotoxin, she resumed taking the supplement and again suffered from considerable hepatotoxicity. Liver biopsy at that time was consistent with acute drug induced liver injury. She, once again, recovered after discontinuation of the supplement. Review of the literature confirms that Chinese skullcap has been implicated as a possible hepatotoxic agent which was demonstrated in this case.展开更多

文摘BACKGROUND Colorectal cancer(CRC)is a global health concern,with advanced-stage diagnoses contributing to poor prognoses.The efficacy of CRC screening has been well-established;nevertheless,a significant proportion of patients remain unscreened,with>70%of cases diagnosed outside screening.Although identifying specific subgroups for whom CRC screening should be particularly recommended is crucial owing to limited resources,the association between the diagnostic routes and identification of these subgroups has been less appreciated.In the Japanese cancer registry,the diagnostic routes for groups discovered outside of screening are primarily categorized into those with comorbidities found during hospital visits and those with CRC-related symptoms.AIM To clarify the stage at CRC diagnosis based on diagnostic routes.METHODS We conducted a retrospective observational study using a cancer registry of patients with CRC between January 2016 and December 2019 at two hospitals.The diagnostic routes were primarily classified into three groups:Cancer screening,follow-up,and symptomatic.The early-stage was defined as Stages 0 or I.Multivariate and univariate logistic regressions were exploited to determine the odds of early-stage diagnosis in the symptomatic and cancer screening groups,referencing the follow-up group.The adjusted covariates were age,sex,and tumor location.RESULTS Of the 2083 patients,715(34.4%),1064(51.1%),and 304(14.6%)belonged to the follow-up,symptomatic,and cancer screening groups,respectively.Among the 2083 patients,CRCs diagnosed at an early stage were 57.3%(410 of 715),23.9%(254 of 1064),and 59.5%(181 of 304)in the follow-up,symptomatic,and cancer screening groups,respectively.The symptomatic group exhibited a lower likelihood of early-stage diagnosis than the follow-up group[P<0.001,adjusted odds ratio(aOR),0.23;95%confidence interval(95%CI):0.19-0.29].The likelihood of diagnosis at an early stage was similar between the follow-up and cancer screening groups(P=0.493,aOR for early-stage diagnosis in the cancer screening group vs follow-up group=1.11;95%CI=0.82-1.49).CONCLUSION CRCs detected during hospital visits for comorbidities were diagnosed earlier,similar to cancer screening.CRC screening should be recommended,particularly for patients without periodical hospital visits for comorbidities.
文摘BACKGROUND Infants'nutrition significantly influences their growth,development,and overall well-being.With the increasing demand for organic infant formula driven by the perception of health benefits and growing awareness of natural feeding options,it is crucial to conduct a comparative analysis of the gastrointestinal tolerability between organic and traditional infant formulas.AIM To provide a concise and precise analysis of the gastrointestinal tolerability of organic infant formula compared to traditional infant formula.Due to limited direct comparisons,the review synthesizes available literature on each formula type,presenting insights into their potential effects on infants'digestive health.METHODS An extensive literature search was conducted,compiling studies on organic and traditional infant formulas,their compositions,and reported effects on gastrointestinal tolerability.We searched academic databases such as PubMed and Google Scholar and specialized nutrition,paediatrics,and infant health journals using relevant keywords till October 1,2023.RESULTS Although specific comparative studies are scarce and formula heterogeneity is a significant limitation,this systematic review provides an in-depth understanding of organic infant formulas'composition and potential benefits.While scientific evidence directly comparing gastrointestinal tolerability is limited,organic formulas strive to use carefully selected organic ingredients to imitate breast milk composition.Potential benefits include improved lipid profiles,higher methionine content,and decreased antibiotic-resistant bacteria levels.Understanding the gastrointestinal tolerability of organic and traditional infant formulas is crucial for parents and healthcare providers to make informed decisions.CONCLUSION Despite limitations in direct comparisons,this systematic review provides insights into the composition and potential benefits of organic infant formulas.It emphasizes the need for further research to elucidate their gastrointestinal effects comprehensively.

文摘BACKGROUND The literature has discussed the relationship between environmental factors and depressive disorders;however,the results are inconsistent in different studies and regions,as are the interaction effects between environmental factors.We hypo-thesized that meteorological factors and ambient air pollution individually affect and interact to affect depressive disorder morbidity.AIM To investigate the effects of meteorological factors and air pollution on depressive disorders,including their lagged effects and interactions.METHODS The samples were obtained from a class 3 hospital in Harbin,China.Daily hos-pital admission data for depressive disorders from January 1,2015 to December 31,2022 were obtained.Meteorological and air pollution data were also collected during the same period.Generalized additive models with quasi-Poisson regre-ssion were used for time-series modeling to measure the non-linear and delayed effects of environmental factors.We further incorporated each pair of environ-mental factors into a bivariate response surface model to examine the interaction effects on hospital admissions for depressive disorders.RESULTS Data for 2922 d were included in the study,with no missing values.The total number of depressive admissions was 83905.Medium to high correlations existed between environmental factors.Air temperature(AT)and wind speed(WS)significantly affected the number of admissions for depression.An extremely low temperature(-29.0℃)at lag 0 caused a 53%[relative risk(RR)=1.53,95%confidence interval(CI):1.23-1.89]increase in daily hospital admissions relative to the median temperature.Extremely low WSs(0.4 m/s)at lag 7 increased the number of admissions by 58%(RR=1.58,95%CI:1.07-2.31).In contrast,atmospheric pressure and relative humidity had smaller effects.Among the six air pollutants considered in the time-series model,nitrogen dioxide(NO_(2))was the only pollutant that showed significant effects over non-cumulative,cumulative,immediate,and lagged conditions.The cumulative effect of NO_(2) at lag 7 was 0.47%(RR=1.0047,95%CI:1.0024-1.0071).Interaction effects were found between AT and the five air pollutants,atmospheric temperature and the four air pollutants,WS and sulfur dioxide.CONCLUSION Meteorological factors and the air pollutant NO_(2) affect daily hospital admissions for depressive disorders,and interactions exist between meteorological factors and ambient air pollution.
文摘BACKGROUND Breast milk is the best and principal nutritional source for neonates and infants.It may protect infants against many metabolic diseases,predominantly obesity and type 2 diabetes.Diabetes mellitus(DM)is a chronic metabolic and microvascular disease that affects all the body systems and all ages from intrauterine life to late adulthood.Breastfeeding protects against infant mortality and diseases,such as necrotizing enterocolitis,diarrhoea,respiratory infections,viral and bacterial infection,eczema,allergic rhinitis,asthma,food allergies,malocclusion,dental caries,Crohn's disease,and ulcerative colitis.It also protects against obesity and insulin resistance and increases intelligence and mental development.Gestational diabetes has short and long-term impacts on infants of diabetic mothers(IDM).Breast milk composition changes in mothers with gestational diabetes.AIM To investigate the beneficial or detrimental effects of breastfeeding on the cardiometabolic health of IDM and their mothers.METHODS We performed a database search on different engines and a thorough literature review and included 121 research published in English between January 2000 and December 15,2022,in this review.RESULTS Most of the literature agreed on the beneficial effects of breast milk for both the mother and the infant in the short and long terms.Breastfeeding protects mothers with gestational diabetes against obesity and type 2 DM.Despite some evidence of the protective effects of breastfeeding on IDM in the short and long term,the evidence is not strong enough due to the presence of many confounding factors and a lack of sufficient studies.CONCLUSION We need more comprehensive research to prove these effects.Despite many obstacles that may enface mothers with gestational diabetes to start and maintain breastfeeding,every effort should be made to encourage them to breastfeed.
文摘Objective To explore the optimal administration route of tranexamic acid(TXA)in shoulder arthroscopic surgery.Methods Patients undergoing arthroscopic rotator cuff repair were randomly divided into four groups:control group(without TXA treatment),intravenous group(TXA was intravenously administered 10 minutes before surgery),irrigation group(TXA was added to the irrigation fluid during subacromial decompression and acromioplasty),and intravenous plus irrigation group(TXA was applied both intravenously and via intra-articular irrigation).The primary outcome was visual clarity assessed with visual analog scale(VAS)score,and the secondary outcomes included irrigation fluid consumption and time to subacromial decompression and acromioplasty procedure.Results There were 134 patients enrolled in the study,including 33 in the control group,35 in the intravenous group,32 in the irrigation group,and 34 in the intravenous plus irrigation group.The median and interquartile range of VAS scores for the intravenous,irrigation,and intravenous plus irrigation groups were 2.70(2.50,2.86)(Z=-3.677,P=0.002),2.67(2.50,2.77)(Z=-3.058,P<0.001),and 2.91(2.75,3.00)(Z=-6.634,P<0.001),respectively,significantly higher than that of the control group[2.44(2.37,2.53)].Moreover,the control group consumed more irrigation fluid than the intravenous group,irrigation group,and intravenous plus irrigation group(all P<0.05).The intravenous plus irrigation group consumed less irrigation fluid than either the intravenous group or the irrigation group(both P<0.001).There was no difference in subacromial decompression and acromioplasty operative time among the four groups.Conclusion TXA applied both topically and systematically can improve intraoperative visual clarity,and the combined application is more effective.
文摘Renal tubular acidosis(RTA)can lead to renal calcification in children,which can cause various complications and impair renal function.This review provides pediatricians with a comprehensive understanding of the relationship between RTA and renal calcification,highlighting essential aspects for clinical manage-ment.The article analyzed relevant studies to explore the prevalence,risk factors,underlying mechanisms,and clinical implications of renal calcification in children with RTA.Results show that distal RTA(type 1)is particularly associated with nephrocalcinosis,which presents a higher risk of renal calcification.However,there are limitations to the existing literature,including a small number of studies,heterogeneity in methodologies,and potential publication bias.Longitudinal data and control groups are also lacking,which limits our understanding of longterm outcomes and optimal management strategies for children with RTA and renal calcification.Pediatricians play a crucial role in the early diagnosis and management of RTA to mitigate the risk of renal calcification and associated complications.In addition,alkaline therapy remains a cornerstone in the treatment of RTA,aimed at correcting the acid-base imbalance and reducing the formation of kidney stones.Therefore,early diagnosis and appropriate therapeutic interventions are paramount in preventing and managing renal calcification to preserve renal function and improve long-term outcomes for affected children.Further research with larger sample sizes and rigorous methodologies is needed to optimize the clinical approach to renal calcification in the context of RTA in the pediatric population.
文摘BACKGROUND Ventilator-associated pneumonia(VAP)is defined as pneumonia that occurs two calendar days following endotracheal intubation or after that.It is the most common infection encountered among intubated patients.VAP incidence showed wide variability between countries.AIM To define the VAP incidence in the intensive care unit(ICU)in the central gove-rnment hospital in Bahrain and review the risk factors and the predominant bacterial pathogens with their antimicrobial susceptibility pattern.METHODS The research was a prospective cross-sectional observational study over six months from November 2019 to June 2020.It included adult and adolescent patients(>14 years old)admitted to the ICU and required intubation and mechanical ventilation.VAP was diagnosed when it occurred after 48 h after endotracheal intubation using the clinical pulmonary infection score,which considers the clinical,laboratory,microbiological,and radiographic evidence.RESULTS The total number of adult patients admitted to the ICU who required intubation and mechanical ventilation during the study period was 155.Forty-six patients developed VAP during their ICU stay(29.7%).The calculated VAP rate was 22.14 events per 1000 ventilator days during the study period,with a mean age of 52 years±20.Most VAP cases had late-onset VAP with a mean number of ICU days before the development of VAP of 9.96±6.55.Gram-negative contributed to most VAP cases in our unit,with multidrug-resistant Acinetobacter being the most identified pathogen.CONCLUSION The reported VAP rate in our ICU was relatively high compared to the international benchmark,which should trigger a vital action plan for reinforcing the implementation of the VAP prevention bundle.
文摘Children with autism spectrum disorders(ASD)or autism are more prone to gastrointestinal(GI)disorders than the general population.These disorders can significantly affect their health,learning,and development due to various factors such as genetics,environment,and behavior.The causes of GI disorders in children with ASD can include gut dysbiosis,immune dysfunction,food sensitivities,digestive enzyme deficiencies,and sensory processing differences.Many studies suggest that numerous children with ASD experience GI problems,and effective management is crucial.Diagnosing autism is typically done through genetic,neurological,functional,and behavioral assessments and observations,while GI tests are not consistently reliable.Some GI tests may increase the risk of developing ASD or exacerbating symptoms.Addressing GI issues in individuals with ASD can improve their overall well-being,leading to better behavior,cognitive function,and educational abilities.Proper management can improve digestion,nutrient absorption,and appetite by relieving physical discomfort and pain.Alleviating GI symptoms can improve sleep patterns,increase energy levels,and contribute to a general sense of well-being,ultimately leading to a better quality of life for the individual and improved family dynamics.The primary goal of GI interventions is to improve nutritional status,reduce symptom severity,promote a balanced mood,and increase patient independence.
文摘Autism spectrum disorder(ASD)is a group of heterogeneous,multi-factorial,neurodevelopmental disorders resulting from genetic and environmental factors interplay.Infection is a significant trigger of autism,especially during the critical developmental period.There is a strong interplay between the viral infection as a trigger and a result of ASD.We aim to highlight the mutual relationship between autism and viruses.We performed a thorough literature review and included 158 research in this review.Most of the literature agreed on the possible effects of the viral infection during the critical period of development on the risk of developing autism,especially for specific viral infections such as Rubella,Cytomegalovirus,Herpes Simplex virus,Varicella Zoster Virus,Influenza virus,Zika virus,and severe acute respiratory syndrome coronavirus 2.Viral infection directly infects the brain,triggers immune activation,induces epigenetic changes,and raises the risks of having a child with autism.At the same time,there is some evidence of increased risk of infection,including viral infections in children with autism,due to lots of factors.There is an increased risk of developing autism with a specific viral infection during the early developmental period and an increased risk of viral infections in children with autism.In addition,children with autism are at increased risk of infection,including viruses.Every effort should be made to prevent maternal and early-life infections and reduce the risk of autism.Immune modulation of children with autism should be considered to reduce the risk of infection.

文摘Inflammatory bowel disease(IBD)is a group of chronic disorders of the gastrointestinal tract comprising Crohn’s disease(CD)and ulcerative colitis(UC).Their etiologies are unknown,but they are characterised by an imbalanced production of pro-inflammatory mediators,e.g.,tumor necrosis factor(TNF)-α,as well as increased recruitment of leukocytes to the site of inflammation.Advantages in understanding the role of the inflammatory pathways in IBD and an inadequate response to conventional therapy in a large portion of patients,has over the last two decades lead to new therapies which includes the TNF inhibitors(TNFi),designed to target and neutralise the effect of TNF-α.TNFi have shown to be efficient in treating moderate to severe CD and UC.However,convenient alternative therapeutics targeting other immune pathways are needed for patients with IBD refractory to conventional therapy including TNFi.Indeed,several therapeutics are currently under development,and have shown success in clinical trials.These include antibodies targeting and neutralising interleukin-12/23,small pharmacologic Janus kinase inhibitors designed to block intracellular signaling of several pro-inflammatory cytokines,antibodies targeting integrins,and small anti-adhesion molecules that block adhesion between leukocytes and the intestinal vascular endothelium,reducing their infiltration into the inflamed mucosa.In this review we have elucidated the major signaling pathways of clinical importance for IBD therapy and highlighted the new promising therapies available.As stated in this paper several new treatment options are under development for the treatment of CD and UC,however,no drug fits all patients.Hence,optimisations of treatment regimens are warranted for the benefit of the patients either through biomarker establishment or other rationales to maximise the effect of the broad range of mode-of-actions of the present and future drugs in IBD.

文摘AIM:To use microarray-based miRNA profiling of colonic mucosal biopsies from patients with ulcerative colitis (UC), Crohn's disease (CD), and controls in order to identify new potential miRNA biomarkers in inflammatory bowel disease. METHODS:Colonic mucosal pinch biopsies from the descending part were obtained endoscopically from patients with active UC or CD, quiescent UC or CD, as well as healthy controls. Total RNA was isolated and miRNA expression assessed using the miRNA microarray Geniom Biochip miRNA Homo sapiens (Febit GmbH, Heidelberg, Germany). Data analysis was carried out by principal component analysis and projection to latent structure-discriminant analysis using the SIMCA-P+12 software package (Umetrics, Umea, Sweden). The microarray data were subsequently validated by quantitative real-time polymerase chain reaction (qPCR) performed on colonic tissue samples from active UC patients (n = 20), patients with quiescent UC (n = 19), and healthy controls (n = 20). The qPCR results were analyzed with Mann-WhitneyU test.In silico prediction analysis were performed to identify potential miRNA target genes and the predicted miRNA targets were then compared with all UC associated susceptibility genes reported in the literature. RESULTS:The colonic mucosal miRNA transcriptome differs significantly between UC and controls, UC and CD, as well as between UC patients with mucosal inflammation and those without. However, no clear differences in the transcriptome of patients with CD and controls were found. The miRNAs with the strongest differential power were identified (miR-20b, miR-99a, miR-203, miR-26b, and miR-98) and found to be upregulated more than a 10-fold in active UC as compared to quiescent UC, CD, and controls. Two miRNAs, miR-125b-1* and let-7e*, were up-regulated more than 5-fold in quiescent UC compared to active UC, CD, and controls. Four of the seven miRNAs (miR-20b, miR-98, miR-125b-1*, and let-7e*) were validated by qPCR and found to be specifically upregulated in patients with UC. Usingin silico analysis we found several predicted pro-inflammatory target genes involved in various pathways, such as mitogen-activated protein kinase and cytokine signaling, which are both key signaling pathways in UC.CONCLUSION:The present study provides the first evidence that miR-20b, miR-98, miR-125b-1*, and let7e* are deregulated in patients with UC. The level of these miRNAs may serve as new potential biomarkers for this chronic disease.

文摘The pathogenesis of inflammatory bowel disease (IBD) is complex and largely unknown. Until recently, research has focused on the study of protein regulators in inflammation to reveal the cellular and molecular networks in the pathogenesis of IBD. However, in the last few years, new and promising insights have been generated from studies describing an association between an altered expression of a specific class of non-coding RNAs, called microRNAs (miRs or miRNAs) and IBD. The short (approximately 22 nucleotides), endogenous, single-stranded RNAs are evolutionary conserved inanimals and plants, and regulate specific target mRNAs at the post-transcriptional level. MiRNAs are involved in several biological processes, including development, cell differentiation, proliferation and apoptosis. Furthermore, it is estimated that miRNAs may be responsible for regulating the expression of nearly one-third of the genes in the human genome. Thus, miRNA deregulation often results in an impaired cellular function, and a disturbance of downstream gene regulation and signaling cascades, suggesting their implication in disease etiology. Despite the identification of more than 1900 mature human miRNAs, very little is known about their biological functions and functional targets. Recent studies have identified dysregulated miRNAs in tissue samples of IBD patients and have demonstrated similar differences in circulating miRNAs in the serum of IBD patients. Thus, there is great promise that miRNAs will aid in the early diagnosis of IBD, and in the development of personalized therapies. Here, we provide a short review of the current state-of-the-art of miRNAs in IBD pathogenesis, diagnostics and therapeutics.
文摘AIM:To investigate the effects of a low fermentable,oligosaccharides,disaccharides,monosaccharides and polyols diet(LFD)and the probiotic Lactobacillus rhamnosus GG(LGG)in irritable bowel syndrome(IBS).METHODS:Randomised,unblinded controlled trial on the effect of 6-wk treatment with LFD,LGG or a normal Danish/Western diet(ND)in patients with IBS fulfilling Rome III diagnostic criteria,recruited betweenNovember 2009 and April 2013.Patients were required to complete on a weekly basis the IBS severity score system(IBS-SSS)and IBS quality of life(IBS-QOL)questionnaires in a specially developed IBS web selfmonitoring application.We investigated whether LFD or LGG could reduce IBS-SSS and improve QOL in IBS patients.RESULTS:One hundred twenty-three(median age 37years,range:18-74 years),90(73%)females were randomised:42 to LFD,41 to LGG and 40 to ND.A significant reduction in mean±SD of IBS-SSS from baseline to week 6 between LFD vs LGG vs ND was revealed:133±122 vs 68±107,133±122 vs 34±95,P<0.01.Adjusted changes of IBS-SSS for baseline covariates showed statistically significant reduction of IBS-SSS in LFD group compared to ND(IBS-SSS score75;95%CI:24-126,P<0.01),but not in LGG compared to ND(IBS-SSS score 32;95%CI:18-80,P=0.20).IBS-QOL was not altered significantly in any of the three groups:mean±SD in LFD 8±18 vs LGG 7±17,LFD 8±18 vs ND 0.1±15,P=0.13.CONCLUSION:LFD is efficacious for patients with IBS.
文摘The use of thiopurines as immunosuppression for the treatment of refractory or chronic active inflammatory bowel disease is established for both Crohn's disease and ulcerative colitis.Nevertheless,many questions remain concerning the optimal treatment regimens of azathioprine,6-mercaptopurine and thioguanine.We will briefly summarize dose recommendations,indications for thiopurine therapy and side effects which are relevant in clinical practice.We discuss some currently debated topics,including the combination of azathioprine and allopurinol,switching of thiopurine therapy in case of side effects,the use of azathioprine in pregnancy,the infection risk using thiopurines and the evidence when to stop thiopurines.Excellent reviews have been published on the thiopurine metabolic pathway which will not be discussed here in detail.
文摘In the present study we report on changes in irritable bowel syndrome-severity scoring system(IBS-SSS)and irritable bowel syndrome-quality of life(IBS-QoL)in 19 IBS patients,aged 18 to 74 years(F/M:14/5),during 12 wk registering their symptoms on the webapplication(www.ibs.constant-care.dk).During a control period of the first 6-wk patients were asked to register their IBS-SSS and IBS-QoL on the web-application weekly without receiving any intervention.Thereafter,low fermentable oligo-,di-,mono-saccharides and polyols(FODMAP)diet(LFD)was introduced for the next6 wk while continuing the registration.Though a small sample size a significant improvement in disease activity(IBS-SSS)was observed during both the control period,median:278(range:122-377),P=0.02,and subsequently during the LFD period,median:151(range:29-334),P<0.01.The IBS-QoL solely changed significantly during the LFD period,median:67(37-120),P<0.01.The significant reduction in disease activity during the control period shows a positive effect of the web-application on IBS symptoms when presented as a"traffic light".However adding the diet reduced IBSSSS to<150,inactive to mild symptoms.In the future results from larger scale trials are awaited.
文摘AIM To develop a scale of domains associated with the health-related quality-of-life(HRQOL) in patients with cirrhosis-related ascites.METHODS We initially undertook literature searches and a qualitative study in order to design a cirrhosis-associated ascites symptom(CAS) scale describing symptoms with a potential detrimental impact on health related quality of life(HRQL)(the higher the score, the worse the symptoms). Discriminatory validity was assessed in a validation cohort including cirrhotic patients with(1) tense/severe;(2) moderate/mild; or(3) no ascites(controls). Patients also completed chronic liver disease questionnaire(CLDQ) and the Euro QoL 5-Dimensions 5-Level(EQ-5D-5L) questionnaire evaluating HRQL. The relation between scale scores was analysed using Spearman correlations. RESULTS The final CAS scale included 14 items. The equivalent reliability was high(Chronbach's alpha 0.88). The validation cohort included 103 patients(72% men, mean age 62.4 years). The mean scores for each question in the CAS scale were higher for patients with severe/tense ascites than for mild/moderate ascites and controls. Compared with controls(mean = 9.9 points), the total CAS scale score was higher for severe/tense ascites(mean = 23.8 points) as well as moderate/mild ascites(mean = 18.6 points)(P < 0.001 both groups). We found a strong correlation between the total CAS and CLDQ score(rho = 0.82, P < 0.001) and a moderate correlation between the CAS and the EQ-5D-5L score(0.67, P < 0.001). CONCLUSION The CAS is a valid tool, which reflects HRQOL in patients with ascites.
文摘The use of herbal supplements has increased considerably over the last decade. We report a case of an elderly woman who began taking Move Free Advanced for arthritis, which in addition to glucosamine and chondroitin, contained two herbal ingredients, Chinese skullcap and Black Catechu. Our patient presented with significant cholestasis and hepatitis which significantly improved after discontinuation of the supplement. Since neither the patient nor the treating physician recognized this supplement as a potential hepatotoxin, she resumed taking the supplement and again suffered from considerable hepatotoxicity. Liver biopsy at that time was consistent with acute drug induced liver injury. She, once again, recovered after discontinuation of the supplement. Review of the literature confirms that Chinese skullcap has been implicated as a possible hepatotoxic agent which was demonstrated in this case.

文摘AIM:To study the indications for sentinel lymph node biopsy(SLNB) in clinically-detected ductal carcinoma in situ(CD-DCIS).METHODS:A retrospective analysis of 20 patients with an initial diagnosis of pure DCIS by an image-guided core needle biopsy(CNB) between June 2006 and June 2012 was conducted at King Faisal Specialist Hospital.The accuracy of performing SLNB in CD-DCIS,the rate of sentinel and non-sentinel nodal metastasis,and the histologic underestimation rate of invasive cancer at initial diagnosis were analyzed.The inclusion criteria were a preoperative diagnosis of pure DCIS with no evidence of invasion.We excluded any patient with evidence of microinvasion or invasion.There were two cases of mammographically detected DCIS and 18 cases of CDDCIS.All our patients were diagnosed by an imageguided CNB except two patients who were diagnosed by fine needle aspiration(FNA).All patients underwent breast surgery,SLNB,and axillary lymph node dissection(ALND) if the SLN was positive.RESULTS:Twenty patients with an initial diagnosis of pure DCIS underwent SLNB,2 of whom had an ALND.The mean age of the patients was 49.7 years(range,35-70).Twelve patients(60%) were premenopausal and 8(40%) were postmenopausal.CNB was the diagnostic procedure for 18 patients,and 2 who were diagnosed by FNA were excluded from the calculation of the underestimation rate.Two out of 20 had a positive SLNB and underwent an ALND and neither had additional non sentinel lymph node metastasis.Both the sentinel visualization rate and the intraoperative sentinel identification rate were 100%.The false negative rate was 0%.Only 2 patients had a positive SLNB(10%) and neither had additional metastasis following an ALND.After definitive surgery,3 patients were upstaged to invasive ductal carcinoma(3/18 = 16.6%) and 3 other patients were upstaged to DCIS with microinvasion(3/18 = 16.6%).Therefore the histologic underestimation rate of invasive disease was 33%.CONCLUSION:SLNB in CD-DCIS is technically feasible and highly accurate.We recommend limiting SLNB to patients undergoing a mastectomy.
