Question: Context: Almost all the past CSWT studies show the beneficial effects on CAD patients in a maximum duration of 1-year follow-up. The aim of this study was to evaluate the actual CSWT effects in 6 years follow-up period.', 'The subjects were selected exclusively on the basis of inclusion criteria. The total number of patients was 52, out of which control group (n = 11) and the shock wave group (SW group, n = 41) was selected.', 'The wall motion, MPI, nitrate dosage, NYHA classification, SAQ scores, CCS grading, 6 MWT were markedly improved in the long-term (6 years) follow-up for SW group than the control group.
Answer: Following 6 years of follow-up, the CSWT provided agreeable results that improved myocardial function and quality of life in comparing to the month 0 and the control group. These outcomes advise that on a long-term (72 months) CSWT shows better parameters than the control group. These findings highlight that CSWT can improve clinical symptoms, morphology, functions of the heart and quality of life in patients with CHD than the patients just on drug therapy for a long-term.

Answer: Does cardiac shock wave therapy show better outcomes in the coronary artery disease patients in a long term?


Question: Context: Side effects of mitotane (o,p'-DDD) have suggested estrogenic effects.", "The objective of the study was to explore o,p'-DDD potential estrogenic effect on SHBG and corticosteroid-binding globulin (CBG).", 'Human hepatoma cell lines (HepG2), lacking estrogen receptor (ER)-alpha, and Hep89, stably transfected by ERalpha, were used.', 'The study was conducted at an academic research laboratory and medical center.', 'The study included 10 male patients with recurrent adrenal carcinoma, receiving mitotane (4-6.5 g daily) for more than 6 months.', 'The main outcome measures were SHBG/CBG mRNA levels measured by real-time PCR, culture medium SHBG/CBG concentrations measured by specific immunoassays, and transient transfection experiments with human SHBG proximal promoter reporter constructs.', "Increased serum SHBG and CBG concentrations, which exceeded normal male limits, were observed in most mitotane-treated patients. In the HepG2 cell line, 17beta-estradiol (E2) or o,p'-DDD treatment had no effect on mRNA or SHBG/CBG concentrations. In contrast, in the Hep89 cell line, E2 increased concentrations of SHBG (r = 0.44, P < 0.0001) and CBG (r = 0.585, P < 0.0001) secreted into culture media in a dose-dependent manner. o,p'-DDD significantly increased SHBG (150% vs. control, P < 0.05) and CBG (184% vs. control, P < 0.05) production by Hep89 cells, at a concentration of 2 x 10(-5) m. Transient transfection experiments in Hep89 cells showed that E2 or o,p'-DDD treatment did not increase the transcriptional activity of the minimal proximal promoter of human SHBG gene.
Answer: Mitotane increased SHBG/CBG gene expression and liver production by mechanisms requiring the presence of ERalpha.

Answer: Does mitotane have an estrogenic effect on sex hormone-binding globulin and corticosteroid-binding globulin in humans?


Question: Context: Total hip replacement (THR) outcomes have been worse for patients with rheumatoid arthritis (RA) compared with those who have osteoarthritis (OA). Whether this remains true in contemporary patients with RA with a high use of disease-modifying and biologic therapy is unknown. The purpose of our study is to assess pain, function, and quality of life 2 years after primary THR, comparing patients with RA and patients with OA.', 'Baseline and 2-year data were compared between validated patients with RA and patients with OA who were enrolled in a single-center THR registry between May 1, 2007, and February 25, 2011.', 'There were 5666 eligible primary THR identified, of which 193 were for RA. RA THR had worse baseline Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC) pain (44.8 vs 53.2, p < 0.001) and function (38.7 vs 49.9, p < 0.001) compared with OA. These differences remained after surgery: pain (88.4 vs 94.0, p < 0.001) and function (82.9 vs 91.8, p < 0.001). Patients with RA were as likely to have a significant improvement as patients with OA (Δ WOMAC > 10) in pain (94% vs 96%, p = 0.35) and function (95% vs 94%, p = 0.69), but were 4 times as likely to have worse function (WOMAC ≤ 60; 19% vs 4%, p < 0.001) and pain (12% vs 3%, p < 0.001). In multivariate logistic regression controlling for multiple potential confounders, RA increased the odds of poor postoperative function (OR 4.32, 95% CI 1.57-11.9), and in patients without a previous primary THR, worse postoperative pain (OR 3.17, 95% CI 1.06-9.53).
Answer: Contemporary patients with RA have significant improvements in pain and function after THR, but higher proportions have worse 2-year pain and function. In addition, RA is an independent predictor of 2-year pain and poor function after THR, despite high use of disease-modifying therapy.

Answer:
Are patients with rheumatoid arthritis more likely to have pain and poor function after total hip replacements than patients with osteoarthritis?
