OBJECTIVES Clinical trials have reported decreased blood loss with the use of tranexamic acid during joint reconstruction. The purpose of this study was to assess the individual practice implications of tranexamic acid use in joint replacement surgery. METHODS Health records of adults undergoing total knee arthroplasty and total hip arthroplasty over a 12-month period were retrospectively rev...
گلوتاتیون s-ترانسفراز، ابرخانواده¬ی ژنی از آنزیم¬های سم¬زدای پلی¬مورفیک هستند که در متابولیسم تعداد زیادی از مواد سرطان¬زای بالقوه نقش دارند. به منظور بررسی ارتباط بین پلی¬مورفیسم¬ در gsts (gstt1، gstm1 و gstp1) و بازال سل کارسینوما، 50 فرد بیمار مبتلا به سرطان bcc و 50 فرد سالم مورد مطالعه قرار گرفتند.. فراوانی ژنوتیپ نول gstm1 در بیماران و گروه کنترل به ترتیب 34% و 6% بود و بنابراین فراوانی آ...
OBJECTIVE To examine the association between three modifiable risk factors (obesity, smoking, and alcohol consumption) and reported joint pain. METHODS Cross sectional data were collected on 858 people aged 58 years living in the West of Scotland and on the same individuals four years later, aged 62 years. RESULTS There was a positive relation between obesity and reported pain in the hips, ...

This paper, determines the confidence interval using the Fisher information under progressive type-II censoring for the k-step exponential step-stress accelerated life testing. We study the performance of these confidence intervals. Finally an example is given to illustrate the proposed procedures.
The censored data are widely used in statistical tests and parameters estimation. In some cases e.g. medical accidents which data are not recorded at the time of occurrence, some methods such as interval censoring are used. In this paper, for a random sample uniformly distributed on the interval (0,θ) the interval censoring have been used. A consistent estimator of θ and some asy...
Tolerance interval is a random interval that contains a proportion of the population with a determined confidence level and is applied in many application fields such as reliability and quality control. In this paper, based on record data, we obtain a two-sided tolerance interval for the exponential population. An example of real record data is presented. Finally, we discuss the accuracy of ...
Background and Objectives: A major challenge that affects the longitudinal studies is the problem of missing data. Missing in the data may result in the loss of part of the information which reduces the accuracy of the estimator and obtain the results will be biased and inaccurate. Therefore, it is necessary to evaluate the missing data mechanism from a longitudinal research and to consider thi...
Previous studies have suggested that smoking might be protective against the development of osteoarthritis (OA) of the knee. A group of 1003 women aged 45-64 years (mean 54.2 years) from the Chingford general population survey were studied to examine the effect of cigarette smoking on the prevalence of radiologically confirmed OA at different sites. Standard anteroposterior radiographs of the h...
