Effectiveness of enhanced diabetes care to patients of South Asian ethnicity : the United Kingdom Asian Diabetes Study (UKADS) : a cluster randomised controlled trial

Background: Delivering high quality and evidence based healthcare to deprived sectors of the community is a major goal for society. We investigated the effectiveness of a culturally sensitive enhanced care package in UK general practice in improving cardiovascular risk factors in South Asian patients with type 2 diabetes. Methods: 21 inner city practices were randomised to intervention (enhanced practice nurse time, link worker and diabetes specialist nurse support) (n=868) or control (standard care) (n=618) groups. Prescribing algorithms with clearly defined targets were provided for all practices. Main outcome measures comprised changes in blood pressure, total cholesterol and glycaemic control (HbA1c) after 2 years. Findings: At baseline, groups were similar with respect to age, sex and cardiovascular risk factors. Comparing treatment groups, after adjustment for confounders, and clustering, differences in diastolic blood pressure (1.91mmHg, P=0.0001) and mean arterial pressure (1.36mmHg, P=0.0180) were significant. There were no significant differences between groups for total cholesterol or HbA1c. Economic analysis indicates the nurse-led intervention was not cost-effective. Across the whole study population systolic blood pressure, diastolic blood pressure and cholesterol decreased significantly by 4.9mmHg, 3.8mmHg and 0.45mmol/L respectively, but there was no change in HbA1c. Interpretation: Additional, although limited, benefits were observed from our culturally enhanced care package over and above the secular changes achieved in the UK in recent years. Stricter targets in general practice and further measures to motivate patients are needed to maximise healthcare outcomes in South Asian patients with diabetes

Patterns of outcome and prognostic factors in primary large cell lymphoma of the testis in a survey of 373 patients by the International Extranodal Lymphoma Study Grfoup (IELSG).

Purpose : To determine clinical features and patterns of outcome of primary testicular diffuse large B-cell lymphomas (DLCL). Patients and Methods: A retrospective international survey of 373 patients with primary testicullar DLCL. Results: Most patients presented with localized disease (stage I to II), and the median age at diagnosis was 66 years (range, 19 to 91 years). Anthracycline-based chemotherapy was administered to 255 patients (68%), and prophylactic intrathecal chemotherapy was given to 68 patients (18%); 133 patients (36%) received prophylactic scrotal radiotherapy. Median overall survival was 4.8 years, and median progression-free survival was 4 years. The survival curves showed no clear evidence of a substantial proportion of cured patients. A favorable international prognostic index score (IPI), no B-symptoms, the use of anthracyclines, and prophylactic scrotal radiotherapy were significantly associated with longer survival at multivariate analysis. However, even for patients with stage I disease and good-risk 1131, the outcome seems worse than what was reported for DLCL at other sites. At a median follow-up of 7.6 years, 195 patients (52%) had relapsed. Extranodal recurrence was reported in 140 cases. Relapses in CNS were detected in 56 patients (15%) up to 10 years after presentation. A continuous risk of recurrence in the contralateral testis was seen in patients not receiving scrotal radiotherapy. Conclusion: Testicular DLCL is characterized by a particularly high risk of extranodal relapse even in cases with localized disease at diagnosis. Anthracycline-based chemotherapy, CNS prophylaxis, and contralateral testicular irradiation seem to improve the outcome. Their efficacy is under evaluation in a prospective clinical trial
