| 1 | Role of fast-setting cements in arthroplasty: A comparative analysis of characteristics显示文摘AIM To evaluate the behaviour of two fast-setting polymethylmethacrylate(PMMA) cements CMW~? 2 G and Palacos~? fast R + G, as reference: Standard-setting Palacos~? R + G.METHODS The fast-setting cements CMW~? 2 G and Palacos~? fast R + G were studied, using standard-setting high viscosity Palacos~? R + G as a reference. Eleven units(of two batch numbers) of each cement were tested. All cements were mixed as specified by the manufacturer and analysed on the following parameters: Handling properties(mixing, waiting, working and hardening phase) according to Kuehn, Mechanical properties according to ISO 5833 and DIN 53435, Fatigue strength according to ISO 16402, Benzoyl Peroxide(BPO)-Content by titration, powder/liquid-ratio by weighing, antibiotic elution profile by High Performance Liquid Chromatography. All tests were done in an acclimatised laboratory with temperatures set at 23.5 ℃± 0.5 ℃ and a humidity of > 40%. RESULTS Palacos~? fast R + G showed slightly shorter handling properties(doughing, hardening phase, n = 12) than CMW~? 2 G, allowing to reduce operative time and to optimise cemented cup implantation. Data of the quasistatic properties of ISO 5833 and DIN 53435 of both cements tested was comparable. The ISO compressive strength(MPa) of Palacos~? fast R + G was significantly higher than CMW~? 2 G, resulting in ANOVA(P < 0.01) and two sample t-test(P < 0.01) at 0.05 level of significance(n = 20). Palacos~? fast R + G showed a higher fatigue strength of about 18% mean(ISO 16402) of 15.3 MPa instead of 13.0 MPa for CMW~? 2 G(n = 5 × 10~6 cycles). Palacos~? fast R + G and CMW~? 2 G differed only by 0.11%(n = 6) with the former having the higher content. The BPO-content of both cements were therefore comparable. CMW~? 2 G had a powder/liquid ratio of 2:1, Palacos~? fast R + G of 2.550:1 due to a higher powder content. Despite its higher gentamicin content, CMW~? 2 G showed a significantly lower antibiotic elution over time than Palacos~? fast R + G(n = 3). CONCLUSION Both cements are compliant with international standards and are highly suitable for their specified surgical indications, affording a time-saving measure without detriment to the mechanical properties. | Neil Ayron Caraan Reinhard Windhager Jason Webb Nadine Zentgraf Klaus-Dieter Kuehn | 2017 | World Journal of Orthopedics2017，8，12： | 2 |

| 3 | Clinical trials in otology:Examining trends and framework for prioritization显示文摘Objective:To characterize otologic clinical trials and examine otologic clinical trial trends from 2008 to 2018 using the clinicaltrials.gov database.Methods:Data was collected from clinicaltrials.gov and included all clinical trials that focused on otology from 2008 to 2018.Outcome measures include status of trials,funding sources,details regarding otologic conditions studied,and trends in clinical trials.Results:There were 992 otology clinical trials from 2008 to 2018.457(46.1%)were completed and 94(9.5%)were discontinued.Industry remained the highest(76.5%)contributor to otology clinical trials.The otologic conditions studied,from most common to least common,include hearing loss(40.6%),vestibulopathy(18.8%),tinnitus(18.8%),and otitis media(15.1%).The number of otology clinical trials increased by an average of 12.0 trials per year from 2008 to 2018(p<0.001).The number of otology clinical trials focusing on hearing loss and vestibulopathy significantly increased over the studied period(p<0.001),while those focusing on tinnitus and otitis media did not(p=0.09 and p=0.20,respectively).The majority of clinical trials on each of these four conditions focused on treatment options.Conclusion:Our study describes trends in otology clinical trials registered on clinicaltrials.gov from 2008 through 2018.The total number of clinical trials over this time period increased significantly,driven by trials investigating hearing loss and vestibulopathy.Furthermore,most clinical trials were industrysponsored and focused on treatment modalities.Our study provides an outline of otology clinical trials registered in a US web-based database,which may be of use for the development of future clinical trials. | Jake Altshuler Rohan Viswanathan Divya B.Dasani Katherine Webb Tam Ramsey Varun Patel Randall Ruffner Jason Mouzakes David Foyt | 2021 | Journal of Otology2021，16，2： | 0 |
