Context: To investigate whether gender is an independent factor associated with disease expression in early rheumatoid arthritis (RA) patients. 438 patients with early RA (disease duration less than one year) were studied. They all were patients with early RA who presented at the Rheumatology Clinic of the University Hospital of Ioannina during the period 1991-2000. All patients fulfilled the American College of Rheumatology criteria for RA. The demographic, clinical, laboratory, radiological and therapeutic characteristics of the disease at diagnosis, and at the last follow-up were analyzed according to gender. We studied 312 women and 126 men with early RA. The female to male ratio was 2.5:1 and the mean age at diagnosis was 49.4 +/- 14.9 years for women and 55.3 +/-15.6 years for men (P < 0.0003). Women had a longer duration of follow-up (P < 0.0003). There were no differences between genders in the general symptoms or the simmetricity of joint involvement at at disease onset. However at disease onset women had a higher erythrocyte sedimentation rate (ESR) (> 30 mm/1st hour), although there were no significant differences between the two groups concerninig the rest of the clinical, laboratory and radiological findings. At the last follow-up women still had a higher ESR (>30 min/1st hour), but no significant differences were found between the two groups concerning the rest of the parameters investigated independently of the follow-up duration. Finally, women and men showed the same degree of radiological changes and functional ability and were treated similarly except for the more frequent use of hydroxychloroquine in women. It seems that gender does not signficantly influence the expression of RA.
Question: Is Rheumatoid Arthritis more common in men or women?

Ex Output:
women

Context: Cyprus is the third largest island and one of the most popular tourist destinations in the Mediterranean Sea. It attracts over 24 million tourists every year.

Context: Ultrasound is an established method of viewing the median nerve in the carpal tunnel syndrome (CTS). There is some evidence to suggest that immediate changes may occur in the median nerve before and after hand activity. The evidence for the validity and reliability of ultrasound for testing acute changes in the median nerve has not been systematically reviewed to date. To evaluate the evidence for visible change in ultrasound appearance of the median nerve after hand activity. A literature search was designed, and three reviewers independently selected published research for inclusion. Two reviewers independently appraised papers using the Evidence Based Library and Information Practice (EBLIP) appraisal checklist, while the third reviewer resolved discrepancies between appraisals. Ten studies were appraised and the results showed an increase in median nerve cross-sectional area following activity, with a return to normal size within 1 h following activity. Both healthy individuals and those diagnosed with CTS participated, all were small convenience samples. Ultrasonographic measurements of the median nerve were reliable in the four studies reporting this, and the studies demonstrated high quality. Good-quality evidence as identified by the EBLIP appraisal checklist suggests that following hand activity, the median nerve changes in size in the carpal tunnel. The results may not be generalizable to all people and activities due to the use of small convenience sampling and narrow range of activities studied, in all of the studies appraised.
Question: What nerve is involved in carpal tunnel syndrome?

Ex Output:
median
