question:
Chronic systemic inflammation plays a pivotal role in the development of atherosclerosis in rheumatoid arthritis (RA). In the present study, we investigated whether anti-TNF-alpha antagonist-monoclonal antibody-infliximab administration alters circulating levels of resistin, a proinflammatory adipokine. We further assessed associations of circulating resistin concentrations with CRP and ESR levels, platelet counts and metabolic syndrome and demographic characteristics in RA patients on periodical treatment with infliximab.', 'We investigated 33 patients with RA on periodical treatment with infliximab. Serum resistin levels were determined immediately prior to and after infliximab infusion.', 'Upon infliximab administration, mean (SD) serum resistin concentrations (ng/ml) decreased from 21.9 (9.9) to 17.4 (8.9) (p=0.005). Also, a significant association between the mean ESR (r=0.405; p=0.03) and CRP (r=0.571; p=0.0005) from disease diagnosis and ESR (r=0.486; p=0.004), CRP (r=0.599; p=0.0005) and platelet count (r=0.559; p=0.0007) at the time of the study and baseline resistin levels was found.
answer:
Does anti-TNF-alpha therapy modulate resistin in patients with rheumatoid arthritis?


question:
In the most recent version of the UICC TNM classification system for thyroid carcinoma, tumors with minimal extrathyroid extension were classified as T3. In this study, we investigated whether this upgrading is appropriate for papillary thyroid carcinoma.', 'We investigated the difference in the relapse-free survival (RFS) rate between patients with tumors having no, minimal, and massive extrathyroid extension in a series of 502 patients over the age of 45 years.', 'Patients with tumors showing massive extension showed a worse RFS rate except for those with tumors measuring 1 cm or less. However, there was no significant difference in RFS between tumors measuring 4 cm or less showing no or minimal extension. In an investigation of 409 patients without any clinically apparent node metastasis, the RFS of patients with tumors larger than 4 cm with massive extension was significantly worse than those with tumors measuring 4 cm or less, while the RFS of patients with tumors with either no or minimal extension did not depend on the tumor size.
answer:
Does minimal extrathyroid extension affect the relapse-free survival of patients with papillary thyroid carcinoma measuring 4 cm or less over the age of 45 years?


question:
A predominance of type 2 helper T cells (Th2) in the bronchoalveolar space and peripheral blood is a well-accepted feature of bronchial asthma. However, the relationship between peripheral blood Th2 cells and asthma severity has not been thoroughly investigated.', 'As Th1 cells predominantly express the chemokine receptor CXCR3 and Th2 cells express CCR4, we assessed the distribution of peripheral blood CXCR3+ and CCR4+ lymphocytes using flow cytometry in 186 patients with asthma and 75 normal subjects.', "The proportion of CXCR3+/CD45RO+ cells in CD4+ T cells increased as the severity of asthma increased. The percentage of CCR4+/CD45RO+ cells in CD4+ T cells were elevated in mild to severe asthma patients compared with controls. However, there was no significant difference in CCR4+/CD45RO+ cells between the mild to severe asthma patients. There was no relationship between the patient's age and the numbers of CXCR3+ or CCR4+ T cells. The percentage of CCR4+ cells in CD45RO+/CD4+ T cells correlated with the levels of total serum IgE (r = 0.630, P < 0.0001).
answer:

Is asthma severity associated with an increase in both blood CXCR3+ and CCR4+ T cells?
