Health-related quality of life and depression in a sample of Latin American adults with rheumatoid arthritis.

OBJECTIVE: To compare the health related quality of life (HRQoL) and depression of individuals with rheumatoid arthritis (RA) to healthy controls in Colombia, as well as to examine the connections between these two variables in individuals with RA. METHOD: One hundred and three individuals with RA were recruited from ambulatory centers in Colombia. Seventy-three control participants were recruited from the local community. Both groups differed with respect to age, gender and marital status (P < 0.001), while education and socio-economic levels were similar. HRQoL was assessed using the Short Form-36 (SF-36) and depressive symptoms were assessed using the Patient Health Questionnaire-9 (PHQ-9). RESULTS: A multivariate analysis of covariance found that RA patients reported substantially higher depressive symptoms and lower HRQoL than healthy controls (P < 0.01 and P < 0.05, respectively). The effect sizes of the differences between patients and controls in HRQoL and depressive symptoms were all large. All SF-36 HRQoL variables were significantly correlated with depressive symptoms in patients and controls (P < 0.05). Social functioning and vitality were uniquely associated with depressive symptoms in the RA group (P < 0.01 and P < 0.05, respectively), whereas education and social functioning were uniquely associated with depressive symptoms in controls (P < 0.05 and P < 0.005, respectively). CONCLUSIONS: Research indicates that individuals with RA have deteriorated HRQoL, and this study extends these findings to a Colombian sample and highlights the importance of the independent relationship between depressive symptoms and vitality in this group of Colombians with RA.

Chronic myeloid leukemia with an e1a3 BCR-ABL fusion protein: transformation to lymphoid blast crisis.

Chronic myelogenous leukemia (CML) results from the neoplastic transformation of a hematopoietic stem cell. CML is cytogenetically characterized by the presence of the Philadelphia chromosome (Ph'). Most patients with CML express e13a2 or e14a2 mRNAs that result from a rearrangement of the major breakpoint cluster regions (M-BCR) generating the 210-kDa (p210BCR-ABL) fusion proteins b2a2 or b3a2 respectively. The e1a3 CML-related atypical translocation has been reported with an indolent clinical course, low leukocyte count, long chronic phase even without treatment and good response to therapy. We report the case of a patient initially diagnosed as CML in chronic phase whose cells expressed the e1a3 variant. The patient readily responded to imatinib 400 mg with the achievement of a rapid complete cytogenetic response and the normalization of the blood count values, but after 5 months transformed into lymphoid blast crisis.

Clinical effectiveness of mud pack therapy in knee osteoarthritis.

OBJECTIVE: The main objective of this study was to systematically review all the scientific studies that analyse the effectiveness of mud pack therapy on patients diagnosed with knee OA. METHODS: One hundred and fifteen publications were identified through an electronic and manual search and 20 of those studies were chosen based on the inclusion criteria: randomized clinical trials, systematic reviews or meta-analyses whose objective was to analyse the effect of mud pack therapy on perceived pain, function and quality of life, with a sample size of ≥20 subjects, published since 2000 and showing conclusive results. RESULTS: In the studies that met the inclusion criteria, 12 analyse functionality, 17 perceived pain, 5 quality of life and all showed a significant improvement in the three analysed variables. The methodological quality of the studies had a moderate risk of bias. CONCLUSION: Mud pack therapy is considered an alternative and effective therapy in the clinical management of knee OA. Studies with better methodology are needed to prove its scope.
