Study

Design and Setting: Systematic review. This is a retrospective analysis of all consecutive phase III RCTs published by eight National Cancer Institute Cooperative Groups up to 2006. Data were extracted from protocols (actual quality) and publications (reported quality) for each study.

Results: Four hundred twenty-nine RCTs met the inclusion criteria. Overall reporting of methodological quality was poor and did not reflect the actual high methodological quality of RCTs. selleck compound The results showed no association between sample size and actual methodological quality of a trial. Poor reporting of allocation concealment and blinding exaggerated the ES by 6% (ratio of hazard ratio [RHR]: 0.94; 95% confidence interval [CI]: 0.88, 0.99) and 24% (RHR: 1.24; 95% CI: 1.05, 1.43), respectively. However, actual quality assessment showed no association between ES and methodological quality.

Conclusion: The largest study to date shows that poor quality of reporting this website does not reflect the actual high methodological quality. Assessment of the impact of quality on the ES based on reported quality can produce misleading results. (C) 2012 Elsevier Inc. All rights reserved.”
“Objective: It was to assess the main characteristics of patients

undergoing pituitary tumor surgery. Method: Eighty-seven patients (44 men; 44.8 +/- 13 years old) were included. Results: The main symptoms were visual alterations

(87.3%), headache (70.1%), diminished libido (34.4%), galactorrhea (22.9%) and hair loss (19.5%). The axes affected were gonadotropic (72.6%), thyrotropic (48.4%) and corticotropic (38.7%), without significant changes after surgery. The average largest tumor diameter was 3.1 cm before surgery and 1.56 cm after surgery. The most frequent postoperative complications were hydro-electrolyte and acid-base disorders (12%), diabetes insipidus (9%), visual field alterations (9%), liquoric fistula (8%) selleck inhibitor and nasal obstruction (7%). The patients were affected by more than one complication. Conclusion: Although a decrease in tumor volume was achieved through surgery, hormonal deficiencies persisted in most of the patients and new surgical approaches were necessary for dealing with tumor recurrence or persistence.”
“Fat mass and obesity-associated protein (FTO) gene expression is known to correlate with obesity. Our aim was to investigate the FTO gene expression in paired omental and subcutaneous human adipose tissues from morbid and obese patients. To understand the role of CD68-positive macrophages in adipose tissues, the correlation with adiposity parameters such as adipocyte diameter and adipocyte radius was also measured. Drug and adiposity correlations were also analyzed.
