Improved metabolic parameters of people with diabetes attending an Aboriginal health service in regional Victoria.

BACKGROUND: Aboriginal and Torres Strait Islander people have higher rates of diabetes and its complications than non-Aboriginal people. Rumbalara Aboriginal Co-operative is the major primary healthcare provider for Aboriginal people in the Greater Shepparton region. AIMS: To evaluate the baseline metabolic parameters and presence of diabetes complications in people with type 2 diabetes attending Rumbalara Aboriginal Co-operative in 2017 and compare it with other Aboriginal and Torres Strait Islander studies and Australian specialist diabetes services. METHODS: Clinical and biochemical characteristics, including diabetes type, age, weight, body mass index (BMI), blood pressure, micro- and macrovascular complications, glycosylated haemoglobin (HbA1c), haemoglobin, renal function, lipid profile, urine albumin:creatinine ratio, diabetes medications, renin angiotensin system inhibition therapies, HMG-CoA reductase inhibitors and antiplatelet agents, were determined. RESULTS: One hundred and twenty-six individuals had diabetes, 121 had type 2 diabetes. One hundred and thirteen identified as Aboriginal and/or Torres Strait Islander. Median age was 57.5 (48-68) years, median HbA1c was 7.8% (6.8-9.6) and median BMI was 33.4 kg/m2 (29-42.3). Compared with other Australian Aboriginal and Torres Strait Islander populations, this population was older and had more obesity, but with better glycaemia management. Compared with specialist diabetes services, this population was of similar age, with greater BMI but comparable HbA1c. CONCLUSIONS: Aboriginal people living with type 2 diabetes attending this regional Aboriginal health service have comparable glycaemic management to specialist diabetes services in Australia, managed largely by primary care physicians with limited access to specialist care for the past 5 years.

Feasibility of once weekly exenatide-LAR and enhanced diabetes care in Indigenous Australians with type 2 diabetes (Long-acting-Once-Weekly-Exenatide laR-SUGAR, 'Lower SUGAR' study).

BACKGROUND: Diabetes is 3-4 times more prevalent in Indigenous Australians with blood glucose levels often above target range. Once weekly formulations of exenatide(exenatide-LAR) have demonstrated significantly greater improvements in glycaemic management with no increased risk of hypoglycaemia and with reductions in bodyweight but have not been studied in Indigenous Australians. AIMS: To assess the feasibility and metabolic effects of once weekly supervised injection of exenatide-LAR in addition to standard care in Indigenous Australians with type 2 diabetes. METHODS: Two communities in Central Australia with longstanding specialist clinical outreach services were allocated by random coin toss to receive once-weekly exenatide-LAR injection with weekly nurse review and adjustment of medication for 20 weeks (community with exenatide-LAR) or to weekly nurse review in addition to standard care over 20 weeks (community without exenatide-LAR). The primary outcome was the feasibility of an intensive diabetes management model of care with and without weekly supervised exenatide-LAR. Secondary outcomes included change in HbA1c. RESULTS: Thirteen participants from the community with exenatide-LAR and nine participants from the community without exenatide-LAR were analysed. Eighty-five percent of individuals in the community with exenatide-LAR and 67% in the community without exenatide-LAR attended more than half of clinic visits. Median difference in the change in HbA1c from baseline to final visit, adjusted for baseline HbA1c, between the community with exenatide-LAR and the community without exenatide-LAR was -3.1%, 95% CI (-5.80%, -0.38%; P = 0.03). CONCLUSIONS: Weekly exenatide-LAR combined with weekly nurse review demonstrated greater improvements in HbA1c, highlighting its potential for use in remote communities.

Relationship between urinary sodium excretion and serum aldosterone in patients with diabetes in the presence and absence of modifiers of the renin-angiotensin-aldosterone system.

Although low dietary salt intake has beneficial effects on BP (blood pressure), low 24hUNa (24 h urinary sodium excretion), the most accurate estimate of dietary salt intake, is associated with increased mortality in people with diabetes. In the non-diabetic population, low salt intake is associated with increased RAAS (renin-angiotensin-aldosterone system) activity. In this cross-sectional study, we examined the relationship between 24hUNa, PRA (plasma renin activity), serum aldosterone and BNP (brain natriuretic peptide) in patients with diabetes. Clinical characteristics, 24hUNa, PRA, serum aldosterone and BNP were recorded in 222 consecutive patients (77% with Type 2 diabetes) attending a diabetes clinic at a tertiary hospital. The relationship between 24hUNa, serum aldosterone, PRA, BNP, urinary potassium excretion, serum potassium, serum sodium, eGFR (estimated glomerular filtration rate), urinary albumin excretion and HbA1c (glycated haemoglobin) was examined by a multivariable regression model. Levels of 24hUNa significantly predicted serum aldosterone in a linear fashion (R²=0.20, P=0.002). In the subgroup of patients (n=46) not taking RAAS-modifying agents, this relationship was also observed (R²=0.10, P=0.03), and the effect of 24hUNa on serum aldosterone was found to be more pronounced than in the whole cohort (coefficient=-0.0014, compared with -0.0008). There was no demonstrable relationship between 24hUNa and PRA or BNP. Low 24hUNa is associated with increased serum aldosterone in people with diabetes, in the presence and absence of RAAS-modifying agents. This raises the possibility that stimulation of the RAAS may be a mechanism that contributes to adverse outcomes observed in patients with low 24hUNa.

Recent advances in management of type 1 diabetes

BACKGROUND: Management options for people with type 1 diabetes mellitus (T1DM) are evolving rapidly. Individuals with T1DM are able to obtain information regarding new therapeutic options online. It is important for all members of the multidisciplinary diabetes care team to keep up with the latest therapies for optimal clinical care of people with T1DM. OBJECTIVE: The aim of this article is to provide an overview of new and changing therapeutic options for management of T1DM. DISCUSSION: Insulin pumps, continuous and flash glucose monitoring and new insulins are changing the treatment landscape for people with T1DM. As well as access to evidence-based medicine, financial and personal factors play a significant role in influencing management choices.

Feasibility of using a transition diabetes team to commence injectable therapies postdischarge from a tertiary hospital: a pilot, randomised controlled trial.

OBJECTIVES: This study aimed to investigate if the use of a transition team was feasible for patients with diabetes being discharged from hospital on injectable diabetes therapies. DESIGN: Pilot, randomised controlled trial. SETTING: The trial was conducted between 2014 and 2016 conjointly by a tertiary referral hospital and a community healthcare provider. PARTICIPANTS: Hospital inpatients (n=105) on new injectable diabetes therapies were randomised 1:1 to transition team or standard care. The transition team received in-home diabetes education 24-48 hours postdischarge, with endocrinologist review 2-4 weeks and 16 weeks postdischarge. MAIN OUTCOME MEASURES: The primary outcome was feasibility, defined by percentage of patients successfully receiving the intervention. Secondary outcomes included safety, defined by hospital readmission and emergency department presentations within 16 weeks postrandomisation, and treatment satisfaction, measured using Diabetes Treatment Satisfaction Questionnaire (DTSQ). Exploratory outcomes included length of stay (LOS) and change in haemoglobin A1c (HbA1c) throughout the study. RESULTS: The intervention was deemed feasible (85% (95% CI 73% to 94%)). No difference in safety between groups was detected. No difference in change in HbA1c between groups was detected (standard care median HbA1c -1.5% (IQR -3.7% to -0.2%) vs transition team median HbA1c -1.9% (IQR -3.8% to -0.2%), p=0.83). There was a trend towards reduced LOS in the transition team group (per protocol, standard care median LOS 8 (IQR 5.5-12); transition team median LOS 6 (IQR 3-12), p=0.06). There was a significant improvement in patient satisfaction in the transition team (standard care median 10.5 (IQR 8.5-16); transition team DTSQ change version median 15 (IQR 10-17.5), p=0.047), although interpretability is limited by missing data. CONCLUSION: This study demonstrated that the use of a novel transition diabetes team is a feasible alternative model of care.

Severe complications of a "Brazilian" bikini wax.

A 20-year-old Australian woman with poorly controlled type 1 diabetes presented with life-threatening Streptococcus pyogenes and Herpes simplex infection of her external genitalia following a routine perineal "Brazilian" bikini wax. Extensive pubic hair removal is now common among young adults in Australia and elsewhere. However, the infectious risks of these practices, particularly among immunosuppressed individuals, are often underappreciated.
