Association of kidney disease measures with risk of renal function worsening in patients with type 1 diabetes

Background: Albuminuria has been classically considered a marker of kidney damage progression in diabetic patients and it is routinely assessed to monitor kidney function. However, the role of a mild GFR reduction on the development of stage 653 CKD has been less explored in type 1 diabetes mellitus (T1DM) patients. Aim of the present study was to evaluate the prognostic role of kidney disease measures, namely albuminuria and reduced GFR, on the development of stage 653 CKD in a large cohort of patients affected by T1DM. Methods: A total of 4284 patients affected by T1DM followed-up at 76 diabetes centers participating to the Italian Association of Clinical Diabetologists (Associazione Medici Diabetologi, AMD) initiative constitutes the study population. Urinary albumin excretion (ACR) and estimated GFR (eGFR) were retrieved and analyzed. The incidence of stage 653 CKD (eGFR < 60 mL/min/1.73 m2) or eGFR reduction > 30% from baseline was evaluated. Results: The mean estimated GFR was 98 \ub1 17 mL/min/1.73m2 and the proportion of patients with albuminuria was 15.3% (n = 654) at baseline. About 8% (n = 337) of patients developed one of the two renal endpoints during the 4-year follow-up period. Age, albuminuria (micro or macro) and baseline eGFR < 90 ml/min/m2 were independent risk factors for stage 653 CKD and renal function worsening. When compared to patients with eGFR > 90 ml/min/1.73m2 and normoalbuminuria, those with albuminuria at baseline had a 1.69 greater risk of reaching stage 3 CKD, while patients with mild eGFR reduction (i.e. eGFR between 90 and 60 mL/min/1.73 m2) show a 3.81 greater risk that rose to 8.24 for those patients with albuminuria and mild eGFR reduction at baseline. Conclusions: Albuminuria and eGFR reduction represent independent risk factors for incident stage 653 CKD in T1DM patients. The simultaneous occurrence of reduced eGFR and albuminuria have a synergistic effect on renal function worsening

Hyposialylation of differentiation-inducer-resistant HL-60 cells.

The total sialic acid concent of retinoic acid (RA)-resistant or 6-thioguanine (6TG)-resistant HL-60 cells was more than tenfold lower and of dimethylsulfoxide (DMSO)-resistant HL-60 cells was approximately twofold lower than that of parental, wild-type (wt) HL-60 cells. Neuraminidase-inaccessible, ie residual cell-associated sialic acid after neuraminidase treatment, was four- to twelvefold lower in the three differentiation-inducer-resistant sublines than in the parent line. Neuraminidase treatment of 125I-labeled surface membrane glycoproteins (SMGs) from wt HL-60 cells converted the two-dimensional gel electrophoretic pattern to one having features in common with RA- and 6TG-resistant cells. However, neuraminidase treatment did not alter the sensitivity of wt HL-60 cells to differentiation induction by RA, hypoxanthine (purine base), or DMSO. These results indicate that differences in peripheral, neuraminidase-accessible sialic acids are important determinants of the gel electrophoretic mobility of the SMGs of the HL-60 line and sublines but are not likely related to the differentiation-resistance mechanism. Further studies are required to determine if hyposialylation of cryptic, neuraminidase-inaccessible sites has functional significance

Message Journal, Edition 4: DESIGN POLITICS What are the politics of your design and what is the design of your politics?

In the Message journal edition 4 we wanted to create an arena where our discipline could discuss the nature and context of its role from an overtly political perspective. Whilst we felt in our bones there was an appetite for this, we were far from certain about its nature, scope and size. Consequently, the call for Message 4 was, to say the least, somewhat of a gamble. Thankfully, our hunches and speculations seem to have been close to the mark. We received more submissions for this call than the previous three issues combined. There was also an anticipation (albeit in hindsight a rather naive one) that some submissions might be positioned around conventional left, right and/or sustainable ecological perspectives. This did not really transpire. Nonetheless, we are very happy to say that the creative, eclectic and diverse nature of the responses has resulted in a range of exemplars that reflect the varied nature, concerns and foci of our vibrant discipline. These extend from John Calvelli’s philosophical dialectic on the fundamental nature and origin of images, their use and effects, to Elizabeth Herrmann’s self-initiated craft-based approach, to do good locally and make a social contribution. Both of these papers are also examples of the higher than usual number of submissions from North America, a substantial proportion of which relate to the politics of cultural and/or racial identity, such as Omari Souza’s, ‘Racist Motifs in Everyday Branding’. Message is dedicated to the development of Graphic Communication Design research. Particularly (although not exclusively) through authors’ analysis of and reflection on their own practice-based research. Through peer reviewed submissions and occasional commissioned essays, Message explores, discusses and challenges the boundaries, roles, practices and outputs of Graphic Communication Design. Past, present and future.</p

The Mondragone relief revisited - Eleusinian cult iconography in Campania

This study of a Classical Attic votive relief found at Mondragone in northern Campania reaffirms the traditional interpretation of the deities depicted on it as members of the Eleusinian cult circle. Drawing on contemporary Eleusinian vase painting, the author argues that the relief depicts episodes from the Homeric Hymn to Demeter. The figure of Dionysos, leaning on the throne of Hades, indicates that this Attic relief was dedicated in a local or domestic sanctuary in Campania by Eleusinian initiates who may also have participated in the Dionysiac-Orphic Mysteries. Thus, the relief is a crucial piece of evidence for the diffusion of the Eleusinian cult abroad

AMD Annals: a model of continuous monitoring and improvement of the quality of diabetes care

OBJECTIVE: in recent years, several initiatives have been launched by the Associazione medici diabetologi (AMD) in the context of a national quality improvement program.These activities include: identification of specific indicators of quality of diabetes care, development of a software to calculate such indicators by using routine clinical data, creation of a network of diabetes clinics and analysis and publication of the results in ad hoc reports (AMD Annals). Through the best performer approach, each centre could compare its own performance not only with the theoretical targets suggested by existing guidelines, but also with the results achieved by the best centres operating within the same healthcare system.We evaluated whether the involvement of diabetes clinics into the AMD Annals initiative improved the quality of care over 4 years. DESIGN: a controlled before and after study was performed to compare data collected from 2004 to 2007 by two groups of centres: group A included centres that had been involved in the project since the first edition of AMD Annals; group B included centres only involved in the last edition. SETTING AND PARTICIPANTS: overall, 124 diabetes clinics provided data on over 100,000 type 2 diabetes patients/year seen from 2004 to 2007. MAIN OUTCOME MEASURES: process indicators included the proportion of patients with at least one measurement of HbA1c, blood pressure and lipid profile during the previous 12 months. Intermediate outcomes included percentages of patients with levels of HbA1c ≤ 7%, blood pressure ≤ 130/85 mmHg and LDL-cholesterol <100 mg/dl (favourable indicators), and the percentages of patients with levels of HbA1c ≥ 9%, blood pressure ≥ 140/90 mmHg and LDL-cholesterol ≥ 130 mg/dl (unfavourable indicators). Percentages of patients treated with insulin, two or more antihypertensive agents, and statins were also evaluated. A multilevel analysis adjusted for age, gender, diabetes duration, and clustering effect was applied to investigate the changes in the indicators between the two groups of centres during 4 years. RESULTS: lipid profile monitoring increased more in group A (+6.2% from 2004 to 2007) than in group B (+2.4%), while HbA1c and blood pressure monitoring did not change over time in both groups. As for the outcomes considered, the percentage of patients with HbA1c ≤ 7% increased by 6% in group A and by 1.3%in group B, while the proportion of patients achieving the blood pressure target increased in group A (+6.4%), but not in group B (-1.4%). A reduction in the percentage of patients with blood pressure ≥ 140/90 mmHg was found in group A (-7.3%) but not in group B (-0.9%). Marked improvements in the proportion of patients with LDL-cholesterol at target were documented in both groups (group A: +10.5%; group B: +12.2%.) The proportion of patients treated with insulin increased in group A only (+5.8%), while the use of statins grew by 20%in both groups.The proportion of individuals treated with two or more antihypertensive drugs increased by 3.6% in group A and by 1.6% in group B. CONCLUSION: the AMD Annals approach can be considered as a case model for quality improvement activities in chronic diseases and a tool to evaluate the level of adoption/acceptance of guidelines in clinical practice. The considerable success documented was obtained without allocation of extra resources or financial incentives but simply through a physician-led effort made possible by the commitment of the specialists involved
