Is point of care testing for anaemia (HB) and microalbumin feasible in people with type 2 diabetes attending diabetes outpatient clinics?

Introduction: Diabetes is the major cause of chronic kidney disease (CKD) in Australia. Anaemia of CKD occurs earlier than in non-diabetics and is often insidious and undetected.

Aim: A large, prospective, single-centre study was undertaken to determine the feasibility of point of care testing (POCT) haemoglobin (Hb) and microalbumin in people with type 2 diabetes (T2DM) attending routine outpatient clinic appointments (OPC).

Method: Clinic nurses measured Hb and microalbumin using the HemoCue Haemoglobin Capillary Analyser and the HemoCue Urine Albumin Analyser (Medipac Scientific), respectively when they tested blood glucose, weight and blood pressure. The nurses were trained to use the analysers before the study commenced. Standard demographic data, duration of diabetes, treatment mode, and presence of complications, comorbidities, and HbA1c were ascertained from patients’ medical records.

Results: Five hundred and fifty-four (80%) patients were screened. The nurses were able to perform the tests competently but testing, especially microalbumin, was time-consuming. Patients’ mean age was 62 years (11 SD): 230 females, mean blood glucose (BG) 10 (3.9 SD) mmol/L, mean haemoglobin 127.2 (16.3 SD) g/L; mean microalbumin 47.8 (58.7 SD) mg/L: 324 were males, mean BG 10.2 (3.9 SD) mmol/L, mean Hb 138.6 (18.8 SD) gm/L, and mean microalbumin 67.9 (73.9 SD) mg/L. 27% of males and 22% of females were anaemic. Of those with anaemia, 27% of females and 29% of males had microalbuminuria.

Conclusions: POCT is feasible in routine outpatient clinics but is time-consuming. One in four T2DM attending OPC were anaemic. POCT Hb testing in OPC is feasible and could identify T2DM who need full haematological assessment.

Adoption and maintenance of gym-based strength training in the community setting in adults with excess weight or type 2 diabetes: a randomized controlled trial

BACKGROUND: Participant adoption and maintenance is a major challenge in strength training (ST) programs in the community-setting. In adults who were overweight or with type 2 diabetes (T2DM), the aim of this study was to compare the effectiveness of a standard ST program (SST) to an enhanced program (EST) on the adoption and maintenance of ST and cardio-metabolic risk factors and muscle strength. METHODS: A 12-month cluster-randomized controlled trial consisting of a 6-month adoption phase followed by a 6-month maintenance phase. In 2008-2009, men and women aged 40-75 years (n = 318) with T2DM (n = 117) or a BMI >25 (n = 201) who had not participated in ST previously were randomized into either a SST or an EST program (which included additional motivationally-tailored behavioral counselling). Adoption and maintenance were defined as undertaking ≥ 3 weekly gym-based exercise sessions during the first 6-months and from 6-12 months respectively and were assessed using a modified version of the CHAMPS (Community Healthy Activity Models Program for Seniors) instrument. RESULTS: Relative to the SST group, the adjusted odds ratio (OR) of adopting ST for all participants in the EST group was 3.3 (95 % CI 1.2 to 9.4). In stratified analyses including only those with T2DM, relative to the SST group, the adjusted OR of adopting ST in the EST group was 8.2 (95 % CI 1.5-45.5). No significant between-group differences were observed for maintenance of ST in either pooled or stratified analyses. In those with T2DM, there was a significant reduction in HbA1c in the EST compared to SST group during the adoption phase (net difference, -0.13 % [-0.26 to -0.01]), which persisted after 12-months (-0.17 % [-0.3 to -0.05]). CONCLUSIONS: A behaviorally-focused community-based EST intervention was more effective than a SST program for the adoption of ST in adults with excess weight or T2DM and led to greater improvements in glycemic control in those with T2DM.
