| 1 | Is the severity of gastroesophageal reflux dependent on hiatus hernia size?显示文摘AIM: To determine if the severity of gastroesophageal reflux disease is dependent on the size of a hiatus hernia. METHODS: Seventy-five patients with either a small(n = 25), medium(n = 25) or large(n = 25) hiatus hernia(assessed by high resolution esophageal manometry) were investigated using 24-h esophageal monitoring and a self-assessed symptom questionnaire. The questionnaire comprised the following items, each graded from 0 to 3 according to severity: heartburn; pharyngeal burning sensation; acid regurgitation; and chest pain. RESULTS: The percentage total reflux time was significantly longer in the group with hernia of 5 cm or more compared with the group with a hernia of < 3 cm(P < 0.002), and the group with a hernia of 3 to < 5 cm(P < 0.04). Pharyngeal burning sensation, heartburn and acid regurgitation were more common with large hernias than small hernias, but the frequency of chest pain was similar in all three hernia groups. CONCLUSION: Patients with a large hiatus hernia are more prone to have pathological gastroesophageal reflux and to have more acid symptoms than patients with a small hiatus hernia. However, it is unlikely that patients with an absence of acid symptoms will have pathological reflux regardless of hernia size. | Thomas Franzén Lita Tibbling | 2014 | World Journal of Gastroenterology2014，20，6： | 14 |
| 2 | Dietary and metabolomic determinants of relapse in ulcerative colitis patients: A pilot prospective cohort study显示文摘AIM To identify demographic, clinical, metabolomic, and lifestyle related predictors of relapse in adult ulcerative colitis(UC) patients.METHODS In this prospective pilot study, UC patients in clinical remission were recruited and followed-up at 12 mo to assess a clinical relapse, or not. At baseline information on demographic and clinical parameters was collected. Serum and urine samples were collected for analysis of metabolomic assays using a combined direct infusion/liquid chromatography tandem mass spectrometry and nuclear magnetic resolution spectroscopy. Stool samples were also collected to measure fecal calprotectin(FCP). Dietary assessment was performed using a validated self-administered food frequency questionnaire. RESULTS Twenty patients were included(mean age: 42.7 ± 14.8 years, females: 55%). Seven patients(35%) experienced a clinical relapse during the follow-up period. While 6 patients(66.7%) with normal body weight developed a clinical relapse, 1 UC patient(9.1%) who was overweight/obese relapsed during the follow-up(P = 0.02). At baseline, poultry intake was significantly higher in patients who were still in remission during follow-up(0.9 oz vs 0.2 oz, P = 0.002). Five patients(71.4%) with FCP > 150 μg/g and 2 patients(15.4%) with normal FCP(≤ 150 μg/g) at baseline relapsed during the follow-up(P = 0.02). Interestingly, baseline urinary and serum metabolomic profiling of UC patients with or without clinical relapse within 12 mo showed a significant difference. The most important metabolites that were responsible for this discrimination were trans-aconitate, cystine and acetamide in urine, and 3-hydroxybutyrate, acetoacetate and acetone in serum. CONCLUSION A combination of baseline dietary intake, fecal calprotectin, and metabolomic factors are associated with risk of UC clinical relapse within 12 mo. | Ammar Hassanzadeh Keshtel iFloris F van den Brand Karen L Madsen Rupasri Mandal Rosica ValchevaKaren I Kroeker Beomsoo Han Rhonda C Bell Janis Cole Thomas Hoevers David S Wishart Richard N Fedorak Levinus A Dieleman | 2017 | World Journal of Gastroenterology2017，23，21： | 9 |
| 3 | Randomized trial in malignant biliary obstruction:Plastic vs partially covered metal stents显示文摘AIM:To compare efficacy and complications of par-tially covered self-expandable metal stent(pcSEMS)to plastic stent(PS)in patients treated for malignant,infrahilar biliary obstruction.METHODS:Multicenter prospective randomized clinical trial with treatment allocation to a pcWallstent(SEMS)or a 10 French PS.Palliative patients aged≥18,for infrahilar malignant biliary obstruction and a Karnofsky performance scale index>60%from 6 participating North American university centers.Primary endpoint was time to stent failure,with secondary outcomes of death,adverse events,Karnofsky performance score and short-form-36 scale administered on a three-monthly basis for up to 2 years.Survival analyses were performed for stent failure and death,with Cox proportional hazards regression models to determine significant predictive characteristics.RESULTS:Eighty-five patients were accrued over 37mo,42 were randomized to the SEMS group and 83patients were available for analyses.Time to stent failure was 385.3±52.5 d in the SEMS and 153.3±19.8 d in the PS group,P=0.006.Time to death did not differ between groups(192.3±23.4 d for SEMS vs211.5±28.0 d for PS,P=0.70).The only significant predictor was treatment allocation,relating to the time to stent failure(P=0.01).Amongst other measured outcomes,only cholangitis differed,being more common in the PS group(4.9%vs 24.5%,P=0.029).The small number of patients in follow-up limits longitudinal assessments of performance and quality of life.From an initially planned 120 patients,only 85 patients were recruited.CONCLUSION:Partially covered SEMS result in a longer duration till stent failure without increased complication rates,yet without accompanying measurable benefits in survival,performance,or quality of life. | Peter L Moses Khalid M AlNaamani Alan N Barkun Stuart R Gordon Roger D Mitty M Stanley Branch Thomas E Kowalski Myriam Martel Viviane Adam | 2013 | World Journal of Gastroenterology2013，19，46： | 6 |

| 5 | 参与式管理解决冲突:遥感和GIS用作瑞典北部驯鹿业土地利用需求信息交流的工具显示文摘在解决复杂的土地管理问题时,对短缺或者有争执的资源进行地理评估有助于不同利益相关者之间沟通认识和增进理解。本文中,我们说明如何使用遥感和GIS收集和汇总瑞典北部驯鹿放牧者和其他土地使用者(林业、采矿业、旅游业等等)的土地使用活动及使用模式的信息。该项目主要基于最终的土地使用者,即驯鹿放牧者们所做的工作,体现了面向土地使用者的新的努力。发展驯鹿业的土地利用规划的基础有以下几个方面:收集并数字化传统的驯鹿栖息地生态学和景观信息;将这些信息与来自野外调查及基于人造卫星观测的植被分类结果整合;绘制其他土地使用者的活动情况图。最终的土地利用规划提供的信息有利于驯鹿放牧者与其他利益相关者之间的磋商,并有助于驯鹿管理实施。该项目可作为一种大众参与和计划编制的模式,从而使本土信息和先进的遥感技术融入一个交互式的过程中。 | Per Sandstrm Tina Granqvist Pahlén Lars Edenius Hans Tφmmervik Olle Hagner Leif Hemberg Hkan Olsson Karin Baer Thomas Stenlund Lars Gran Brandt Mikael Egberth 周立志 程利群 | 2003 | AMBIO-人类环境杂志2003，32，8： | 4 |
| 6 | Three-dimensional analysis of the physiological foramen geometry of maxillary and mandibular molars by means of micro-CT显示文摘The aim of this study was to investigate the physiological foramen diameter, shape and distance between physiological and anatomical apex of maxillary and mandibular first and second molars. Accurate knowledge of the physiological foramina morphology; thus, inherent mechanical shaping technical hindrances, is decisive when taking the corresponding root canal final preparation decision. The morphological dimensions of a total of 1 727 physiological foramina were investigated by means of micro-computed tomography. Mean narrow and wide(to a high number, oval) diameters of the physiological foramen were 0.24,0.22 and 0.33 mm and 0.33, 0.31 and 0.42 mm in mesiobuccal(MB), distobuccal(DB) and palatal(P) roots in maxillary first molars; 0.24, 0.22 and 0.33 mm and 0.41, 0.33 and 0.44 in MB, DB, and P roots in maxillary second molars. Mandibular first molars showed mean narrow and wide diameters of 0.24 and 0.30 mm and of 0.39 and 0.46 mm in mesial(M) and distal(D)roots; second mandibular molars showed 0.25 and 0.31 mm and 0.47 mm in M and D roots. The mean distance between the physiological foramina and anatomical apex was 0.82, 0.81 and 1.02 mm and 0.54, 0.43 and 0.63 mm in MB, DB and P roots of the maxillary first and second molars, respectively. A mean distance of 0.95 mm(M) and 1.05 mm(D) in the first and0.78 mm(M) and 0.81 mm(D) in the second mandibular molars was observed. Based on the results obtained, assumable recommendations for final preparation size of the physiological foramen were calculated. However, when taking into consideration, the resulting standard deviations of marginal errors must be cautiously considered when taking a final decision in clinical endodontic treatment. | Thomas Gerhard Wolf Frank Paqué Michael Sven Patyna Brita Willershausen Benjamín Briseno-Marroquín | 2017 | International Journal of Oral Science2017，9，3： | 4 |
| 7 | Detection of flock movement and behaviour of broiler chickens at different feeders using image analysis显示文摘The behaviour of broiler chickens has been extensively studied as a function of stocking density and environmental conditions,but limited information was reported in the scientific literature about the effect of feeder type on birds’feeding process.The main objective of this study was to assess the effects of three different feeder types in relation to the birds’behaviour in its surroundings.The analysed feeders were:tube-type with partition grid(F1);tube-type without partition grid(F2);and automatic type with partition grid(F3).The considered variables were:occupied area(OA);activity index(AI)(flock movement);total birds presented in the area(TB);and birds effectively eating(EE).OA and AI were calculated by computational image analysis while TB and EE were manually measured.The results indicated that the feeder type could have influenced the birds’behaviour regarding to OA(R2=0.56),TB(R2=0.48),and EE(R2=0.40),but AI(R2=0.01)was not found to be directly influenced by the feeder type.A higher percentage of birds effectively eating were found in F2(86.4%),which was the one with the largest free area to access the feed.Similar average number of total birds was found in F1,but with a lower percentage of individuals effectively eating(63.3%),which means that birds were nearby this feeder performing other behaviours.Since the assessed feeders were in the same house under the same conditions,it can be suggested that not only the free area to access the feed but potentially the design of feeders could have influenced the birds’feeding preference.The real beneficial effect of the adoption of partition grid on feed trays is still uncertain,and it is also unclear whether the financial value of reduced wastage would compensate the possible reduction in feed intake. | Diego Pereira Neves Saman Abdanan Mehdizadeh Matthew Tscharke Irenilza de Alencar Nääs Thomas Michael Banhazi | 2015 | Information Processing in Agriculture2015，2，3： | 4 |
| 8 | Prevalence and virological profiles of hepatitis B infection in human immunodeficiency virus patients显示文摘AIM: To determine the prevalence of hepatitis B virus (HBV) in adult human immunodeficiency virus (HIV) patients with CD4+ T-cell count less than 500/mm 3 and without antiretroviral therapy; to describe different HBV-HIV coinfection virological profiles; and to search for factors associated with HBs antigen (HBsAg) presence in these HIV positive patients.METHODS: During four months (June through September 2006), 491 patients were received in four HIV positive monitoring clinical centers in Abidjan. Inclusion criteria: HIV-1 or HIV-1 and 2 positive patients, age ≥ 18 years, CD4+ T-cell count < 500/mL and formal and signed consent of the patient. Realized blood tests included HIV serology, CD4+ T-cell count, quantitative HIV RNA load and HBV serological markers, such as HBsAg and HBc antibody (anti-HBcAb). We performed HBeAg, anti-HBe antibody (anti-HBeAb), anti-HBc IgM and quantitative HBV DNA load in HBsAg positive patients. Anti-HBsAb had been tested in HIV patients with HBsAg negative and anti-HBcAb-positive. HBV DNA was also tested in 188 anti-HBcAb positive patients with HBsAg negative status and without anti-HBsAb. Univariate analysis (Pearsonχ 2 test or Fischer exact test) and multivariate analysis (backward step-wise selection logistic regression) were performed as statistical analysis. RESULTS: Mean age of 491 patients was 36 ± 8.68 years and 73.3% were female. Type-1 HIV was found in 97% and dual-type HIV (type 1 plus type 2) in 3%. World Health Organization (WHO) clinical stage was 1, 2, 3 and 4 respectively in 61 (12.4%), 233 (47.5%), 172 (35%) and 25 patients (5.1%). Median CD4+ T-cell count was 341/mm 3 (interquartile range: 221-470). One hundred and twelve patients had less than 200 CD4+ T-cell/mm 3 . Plasma HIV-1 RNA load was elevated (≥ 5 log 10 copies/mL) in 221 patients (45%). HBsAg and anti-HBcAb prevalence was respectively 13.4% and 72.9%. Of the 66 HBsAg positive patients, 22 were inactive HBV carriers (33.3%), 21 had HBeAg positive hepatitis (31.8%) and 20 had HBeAg negative hepatitis (30.3%). HBeAg and anti-HBeAb were indeterminate in 3 of them. Occult B infection prevalence (HBsAg negative, anti-HBcAb positive, anti-HBsAb negative and detectable HBV DNA) was 21.3%. Three parameters were significantly associated with the presence of HBsAg: male [odds ratio (OR): 2.2;P = 0.005; 95% confidence interval (CI): 1.3-3.8]; WHO stage 4 (OR: 3.2;P = 0.01;95% CI: 1.3-7.9); and aspartate aminotransferase (AST) level higher than the standard (OR: 1.9;P = 0.04; 95% CI: 1.02-3.8). CONCLUSION: HBV infection prevalence is high in HIV-positive patients. HBeAg positive chronic hepatitis and occult HBV infection are more frequent in HIVpositive patients than in HIV negative ones. Parameters associated with HBsAg positivity were male gender, AIDS status and increased AST level. | Koffi Alain Attia Serge Eholié Eugène Messou Christine Danel Sandrine Polneau Henri Chenal Thomas Toni Myreille Mbamy Catherine Seyler Naomi Wakasugi Thérèse N'dri-Yoman Xavier Anglaret | 2012 | World Journal of Hepatology2012，4，7： | 4 |

| 13 | Genotype phenotype correlation in Wilson's disease within families-a report on four south Indian families显示文摘AIM: To study the genotype phenotype correlation in Wilson's disease (WD) patients within families. METHODS: We report four unrelated families from South India with nine members affected with WD. Phenotype was classified as per international consensus phenotypic classifi cation of WD. DNA was extracted from peripheral blood and 21 exons of ATP7B gene and flanking introns were amplified by polymerase chain reaction (PCR). The PCR products were screened for mutations and the aberrant products noted on screening were sequenced. RESULTS: Four separate ATP7B mutations were found in the four families. ATP7B mutations were identical amongst affected members within each family. Three families had homozygous mutations of ATP7B gene while one family had compound heterozygous mutation, of which only one mutation was identifi ed. We noted concordance between ATP7B gene mutation and Wilson's disease phenotype amongst members within each family. The age of onset of symptoms or of detection of asymptomatic disease, baseline serum ceruloplasmin and baseline urinary copper levels were also similar in affected members of each family. Minor differences in phenotype and baseline serum ceruloplasmin level were noted in one family.CONCLUSION: We report concordance between ATP7B mutation and WD phenotype within each family with > 1 member affected with WD. Homozygous ATP7B mutation was present in 3 of the 4 families studied. Our report supports allelic dominance as a determinant of WD phenotype. However, in one family with compound heterozygous mutation, there was a similar WD phenotype which suggests that there may be other factors determining the phenotype. | S Santhosh RV Shaji CE Eapen V Jayanthi S Malathi P Finny N Thomas M Chandy G Kurian GM Chandy | 2008 | World Journal of Gastroenterology2008，14，29： | 3 |
| 14 | Impact of global climate change on the health,welfare and productivity of intensively housed livestock显示文摘Major scientific studies have shown that global warming(i.e.increasing average temperature of the Earth)is now a reality.The aims of this paper are to broadly review the underlining causes of global warming,the general effects of global warming on social and environmental systems and the specific effects of resulting from global warming phenomena severe fluctuations in weather patterns,particularly heat waves on livestock health,welfare and productivity.Finally this article aims to summarise some common sense climate control methods and more importantly to highlight the required future research and development(R&D)work that is necessary to achieve a new level of building environment control capability,and thus ensure that the intensive livestock industries will be able to cope with the changed external climate.With the increasing temperatures on a global scale,the most direct effect of the high temperature on the animals is heat stress,which has been proven to have a variety of negative effects on animal health,welfare and productivity.Different potential measures could be taken in future to alleviate the increased heat stress.Some of these measures are mere adaptations or improvements of current engineering solutions.However,facing the complex challenges of global warming and particularly resulting from it the rapid increase of the number of consecutive days with significantly higher than average temperatures will probably require novel solutions,including new designs based on solid engineering judgment,development of new engineering standards and codes to guide designs,the exploration of new and superior building materials,the need for better energy management,and the development of substantially more“intelligent”control systems that will balance changing exterior disturbances,interior building loads and demands to the biological needs of the occupants of the structures. | Tadeusz Kuczynski Victoria Blanes-Vidal Baoming Li Richard S.Gates Irenilza de Alencar Nääs Daniella J.Moura Daniel Berckmans Thomas M.Banhazi | 2011 | International Journal of Agricultural and Biological Engineering2011，4，2： | 3 |

| 16 | Th1 cytokines promote T-cell binding to antigen-presenting cells via enhanced hyaluronan production and accumulation at the immune synapse显示文摘Hyaluronan(HA)production by dendritic cells(DCs)is known to promote antigen presentation and to augment T-cell activation and proliferation.We hypothesized that pericellular HA can function as intercellular‘glue’directly mediating T cell–DC binding.Using primary human cells,we observed HA-dependent binding between T cells and DCs,which was abrogated upon pre-treatment of the DCs with 4-methylumbelliferone(4-MU),an agent which blocks HA synthesis.Furthermore,T cells regulate HA production by DCs via T cell-derived cytokines in a T helper(Th)subset-specific manner,as demonstrated by the observation that cell-culture supernatants from Th1 but not Th2 clones promote HA production.Similar effects were seen upon the addition of exogenous Th1 cytokines,IL-2,interferon c(IFN-c)and tumor necrosis factor a(TNF-a).The critical factors which determined the extent of DC–T cell binding in this system were the nature of the pre-treatment the DCs received and their capacity to synthesize HA,as T-cell clones which were pre-treated with monensin,added to block cytokine secretion,bound equivalently irrespective of their Th subset.These data support the existence of a feedforward loop wherein T-cell cytokines influence DC production of HA,which in turn affects the extent of DC–T cell binding.We also document the presence of focal deposits of HA at the immune synapse between T-cells and APC and on dendritic processes thought to be important in antigen presentation.These data point to a pivotal role for HA in DC–T cell interactions at the IS. | Paul L Bollyky Stephen P Evanko Rebecca P Wu Susan Potter-Perigo S Alice Long Brian Kinsella Helena Reijonen Kelly Guebtner Brandon Teng Christina K Chan Kathy R Braun John A Gebe Gerald T Nepom Thomas N Wight | 2010 | Cellular & Molecular Immunology2010，7，3： | 3 |
| 17 | Root canal morphology and configuration of 123 maxillary second molars by means of micro-CT显示文摘The aim of this study was to investigate the root canal configuration, accessory canals and number of main foramina of 123 maxillary second molars by means of micro-computed tomography. The teeth were scanned and reproduced with 3D software imaging. The root canal configuration and number of main foramina were evaluated by means of a four-digit system. The morphological complexity of human maxillary second molars is depicted by the number of accessory and connecting canals. The most frequently observed root canal configurations in the mesiobuccal root were 2-2-2/2(19.5%), 2-2-1/1(14.6%) and 2-1-1/1(13.0%). A 1-1-1/1 configuration was observed in 93.5% and in 96.7% in the distobuccal and palatal roots, respectively. The MB1 root canal had one accessory canal(18.7%), and 8.9% of the MB2 root canal had one or two accessory canals. The distobuccal(11.3%) and palatal(14.6%) root canals had at least one accessory canal, and connecting canals were observed in16.3% of mesiobuccal roots. The MB1, MB2, distobuccal and palatal root canals had one main foramen in 99.2%, 43.1%,98.4% and 99.2% of samples, respectively. In the mesiobuccal root, one accessory foramen was detected in 14.6%, two were detected in 7.3%, and three were detected in 5.7%. The distobuccal root showed one or two accessory foramina in 9.1% of samples. The root canal configuration of maxillary second molars is quite heterogeneous; the mesiobuccal root has predominantly two root canal entrances(58.4%, 1 in 41.1%) with one main foramen(54.4%). Two main foramina were observed in 43.0%. Morphological variations, connecting and accessory canals were observed in all apical thirds. | Thomas Gerhard Wolf Frank Paqué Anja-Christin Woop Brita Willershausen Benjamín Briseno-Marroquín | 2017 | International Journal of Oral Science2017，9，1： | 3 |
| 18 | 22-gauge core vs 22-gauge aspiration needle for endoscopic ultrasound-guided sampling of abdominal masses显示文摘AIM To compare the aspiration needle(AN) and core biopsy needle(PC) in endoscopic ultrasound-guided fine needle aspiration(EUS-FNA) of abdominal masses.METHODS Consecutive patients referred for EUS-FNA were included in this prospective single-center trial. Each patient underwent a puncture of the lesion with both standard 22-gauge(G) AN(Echo Tip Ultra; Cook Medical, Bloomington, Indiana, United States) and the novel 22 G PC(Echo Tip Pro Core; Cook Medical, Bloomington, Indiana, United States) in a randomized fashion; histology was attempted in the PC group only. The main study endpoint was the overall diagnostic accuracy, including the contribution of histology to the final diagnosis. Secondary outcome measures included material adequacy, number of needle passes, and complications.RESULTS Fifty six consecutive patients(29 men; mean age 68 years) with pancreatic lesions(n = 38), lymphadenopathy(n = 13), submucosal tumors(n = 4), or others lesions(n = 1) underwent EUS-FNA using both of the needles in a randomized order. AN and PC reached similar overall results for diagnostic accuracy(AN: 88.9 vs PC: 96.1, P = 0.25), specimen adequacy(AN: 96.4% vs PC: 91.1%, P = 0.38), mean number of passes(AN: 1.5 vs PC: 1.7, P = 0.14), mean cellularity score(AN: 1.7 vs PC: 1.1, P = 0.058), and complications(none). A diagnosis on the basis of histology was achieved in the PC group in 36(64.3%) patients, and in 2 of those as the sole modality. In patients with available histology the mean cellularity score was higher for AN(AN: 1.7 vs PC: 1.0, P = 0.034); no other differences were of statistical significance.CONCLUSION Both needles achieved high overall diagnostic yields and similar performance characteristics for cytological diagnosis; histological analysis was only possible in 2/3 of cases with the new needle. | William Sterlacci Athanasios D Sioulas Lothar Veits Pervin G?nüllü Guido Schachschal Stefan Groth Mario Anders Christos K Kontos Theodoros Topalidis Andrea Hinsch Michael Vieth Thomas R?sch Ulrike W Denzer | 2016 | World Journal of Gastroenterology2016，22，39： | 2 |
| 19 | Gastrointestinal and liver disease in patients with schizophrenia:A narrative review显示文摘Schizophrenia is a severe mental illness which can have a devastating impact onan individual’s quality of life. Comorbidities are high amongst patients and lifeexpectancy is approximately 15 years less than the general population. Despite thewell-known increased mortality, little is known about the impact of gastrointestinaland liver disease on patients with schizophrenia. We aimed to reviewthe literature and to make recommendations regarding future care. Literaturesearches were performed on PubMed to identify studies related to gastrointestinaland liver disease in patients with schizophrenia. High rates of chronic liverdisease were reported, with Non-Alcoholic Fatty Liver Disease being of particularconcern;antipsychotics and metabolic syndrome were contributing factors. Ratesof acute liver failure were low but have been associated with antipsychotic useand paracetamol overdose. Coeliac disease has historically been linked to schizophrenia;however, recent research suggests that a causal link is yet to be proven.Evidence is emerging regarding the relationships between schizophrenia andpeptic ulcer disease, inflammatory bowel disease and irritable bowel syndrome;clinical vigilance regarding these conditions should be high. Patients with schizophreniapoorly engage with bowel cancer screening programmes, leading to latediagnosis and increased mortality. Clozapine induced constipation is a significantissue for many patients and requires close monitoring. There is a significantburden of gastrointestinal and liver disease amongst patients with schizophrenia.Better levels of support from all members of the medical team are essential toensure that appropriate, timely care is provided. | Rebecca K Grant William M Brindle Mhairi C Donnelly Pauline M McConville Thomas G Stroud Lorenzo Bandieri John N Plevris | 2022 | World Journal of Gastroenterology2022，28，38： | 2 |
| 20 | Should antibiotics be administered before arthroscopic knee surgery? A systematic review of the literature显示文摘AIM To explore the current evidence surrounding the administration of prophylactic antibiotics for arthroscopic knee surgery. METHODS Databases were searched from inception through May of 2018 for studies examining prophylactic antibiotic use and efficacy in knee arthroscopy. Studies with patient data were further assessed for types of arthroscopic procedures performed,number of patients in the study,use of antibiotics,and outcomes with the intention of performing a pooled analysis. Data pertaining to 'deep tissue infection' or 'septic arthritis' were included in our analysis. Reported data on superficial infection were not included in our data analysis. For the pooled analysis,a relative risk ratio was calculated and χ~2 tests were used to assess for statistical significance between rates of infection amongst the various patient groups. Post hoc power analyses were performed to compute the statistical power obtained from our sample sizes. Number needed to treat analyses were performed for statistically significant differences by dividing 1 by the difference between the infection rates of the antibiotic and no antibiotic groups. An alpha value of 0.05 was used for our analysis. Study heterogeneity was assessed by Cochrane's Q test as well as calculation of the I^2 value.RESULTS A total of 49682 patients who underwent knee ar-throscopy for a diverse set of procedures across 19 studies met inclusion critera for pooled analysis. For those not undergoing graft procedures,there were 27 cases of post-operative septic arthritis in 34487 patients(0.08%) who received prophylactic antibiotics and 16 cases in 10911(0.15%) who received none [risk ratio(RR) = 0.53,95% confidence interval(CI): 0.29-0.99,P = 0.05]. A sub-group analysis in which bony procedures were excluded was performed which found no significant difference in infection rates between patients that received prophylactic antibiotics and patients that did not(P > 0.05). All anterior cruciate ligament reconstruction studies used prophylactic antibiotics,but two studies investigating the effect of soaking the graft in vancomycin in addition to standard intravenous(IV) prophylaxis were combined for analysis. There were 19 cases in 1095 patients(1.74%) who received IV antibioitics alone and no infections in 2034 patients who received IV antibiotics and had a vancomycin soaked graft(RR = 0.01,95%CI: 0.001-0.229,P < 0.01).CONCLUSION Prophylactic antibiotics are effective in preventing septic arthritis following simple knee arthroscopy. In procedures involving graft implantation,graft soaking reduces the rate of infection. | John Carney Nathanael Heckmann Erik N Mayer Ram K Alluri Carleton Thomas Vangsness George F Hatch Ⅲ Alexander E Weber | 2018 | World Journal of Orthopedics2018，9，11： | 2 |
