Exercise training improves vascular function in adolescents with type 2 diabetes.

The impact of exercise training on vascular health in adolescents with type 2 diabetes has not been previously studied. We hypothesized that exercise training would improve micro- and macrovascular health in adolescents with type 2 diabetes. Thirteen adolescents (13-21 years, 10F) with type 2 diabetes were recruited from Princess Margaret Hospital. Participants were randomized to receive either an exercise program along with standard clinical care (n = 8) or standard care alone (n = 5). Those in the intervention group received 12 weeks of gym-based, personalized, and supervised exercise training. Those in the control group were instructed to maintain usual activity levels. Assessments were conducted at baseline and following week 12. The exercise group was also studied 12 weeks following the conclusion of their program. Assessments consisted of conduit artery endothelial function (flow-mediated dilation, FMD) and microvascular function (cutaneous laser Doppler). Secondary outcomes included body composition (dual-energy X-ray absorptiometry, DXA), glycemic control (whole body insulin sensitivity, M) assessed using the euglycemic-hyperinsulinemic clamp protocol, cardiorespiratory fitness (V˙O2peak), and muscular strength (1RM). Exercise training increased FMD (P < 0.05), microvascular function (P < 0.05), total lean mass (P < 0.05), and muscle strength (P < 0.001). There were no changes in cardiorespiratory fitness, body weight, BMI, or M. In the control group, body weight (P < 0.01), BMI (P < 0.01), and total fat mass (P < 0.05) increased. At week 24, improvements in vascular function were reversed. This study indicates that exercise training can improve both conduit and microvascular endothelial function and health, independent of changes in insulin sensitivity in adolescents with type 2 diabetes

'Next Generation Youth Well-being Study:' understanding the health and social well-being trajectories of Australian Aboriginal adolescents aged 10-24 years: study protocol

INTRODUCTION:Australian Aboriginal and/or Torres Strait Islander (hereafter referred to as 'Aboriginal') adolescents (10-24 years) experience multiple challenges to their health and well-being. However, limited evidence is available on factors influencing their health trajectories. Given the needs of this group, the young age profile of the Aboriginal population and the long-term implications of issues during adolescence, reliable longitudinal data are needed. METHODS AND ANALYSIS:The 'Next Generation: Youth Well-being Study' is a mixed-methods cohort study aiming to recruit 2250 Aboriginal adolescents aged 10-24 years from rural, remote and urban communities in Central Australia, Western Australia and New South Wales. The study assesses overall health and well-being and consists of two phases. During phase 1, we qualitatively explored the meaning of health and well-being for adolescents and accessibility of health services. During phase 2, participants are being recruited into a longitudinal cohort. Recruitment is occurring mainly through community networks and connections. At baseline, participants complete a comprehensive survey and undertake an extensive age relevant clinical assessment. Survey and clinical data will be linked to various databases including those relating to health services; medication; immunisation; hospitalisations and emergency department presentations; death registrations; education; child protection and corrective services. Participants will receive follow-up surveys approximately 2 years after their baseline visit. The 'Next Generation' study will fill important evidence gaps by providing longitudinal data on the health and social well-being of Aboriginal adolescents supplemented with narratives from participants to provide context. ETHICS AND DISSEMINATION:Ethics approvals have been sought and granted. Along with peer-reviewed publications and policy briefs, research findings will be disseminated via reports, booklets and other formats that will be most useful and informative to the participants and community organisations.Lina Gubhaju, Emily Banks, James Ward, Catherine D, Este, Rebecca Ivers ...

Non-medical prescribing versus medical prescribing for acute and chronic disease management in primary and secondary care.

The aim of this Cochrane review was to find out if prescribing by health professionals other than doctors delivers comparable outcomes to prescribing by doctors. Cochrane researchers collected and analysed all relevant studies to answer this question and found 46 studies. Key messages With appropriate training and support, nurses and pharmacists are able to prescribe medicines as part of managing a range of conditions to achieve comparable health management outcomes to doctors. The majority of studies focus on chronic disease management in higher-income counties where there is generally a moderate-certainty of evidence supporting similar outcomes for the markers of disease in high blood pressure, diabetes, and high cholesterol. Further high-quality studies are needed in poorer countries and to better quantify differences in prescribing outcomes for adverse events, and to determine health economic outcomes. Further studies could also focus more specifically on the prescribing component of care. What was studied in the review? A number of countries allow health professionals other than doctors to prescribe medicines. This shift in roles is thought to provide improved and timely access to medicines for consumers where there are shortages of doctors or the health system is facing pressures in coping with the burden of disease. In addition, this task shift has been supported by a number of governments as a way to more appropriately use the skills of health professionals, such as nurses and pharmacists, in the care of patients. We compared the outcomes of any healthcare workers who were prescribing with a high degree of autonomy with medical prescribers in the hospital or community setting in low-, middle- and high-income countries. What are the main results of the review? This review found 45 studies where nurses and pharmacists with high levels of prescribing autonomy were compared with usual care medical prescribers. A further study compared nurse prescribing with guideline support with usual nurse prescribing care. No studies were found with other health professionals or lay prescribers. Four nurse prescribing studies were undertaken in the low- and middle-income settings of Colombia, South Africa, Uganda, and Thailand. The remainder of studies were undertaken in high-income Western countries. Forty-two studies were based in a community setting, two studies were located in hospitals, one study in the workplace, and one study in an aged care facility. Prescribing was but one part of many health-related interventions, particularly in the management of chronic disease. The review found that the outcomes for non-medical prescribers were comparable to medical prescribers for: high blood pressure (moderate-certainty of evidence); diabetes control (high-certainty of evidence); high cholesterol (moderate-certainty of evidence); adverse events (low-certainty of evidence); patients adhering to their medication regimeans (moderate-certainty of evidence); patient satisfaction with care (moderate-certainty of evidence); and health-related quality of life (moderate-certainty of evidence). Pharmacists and nurses with varying levels of undergraduate, postgraduate, and specific on-the-job training related to the disease or condition were able to deliver comparable prescribing outcomes to doctors. Non-medical prescribers frequently had medical support available to facilitate a collaborative practice model

Impact of an integrated diabetes service involving specialist outreach and primary health care on risk factors for micro- and macrovascular diabetes complications in remote Indigenous communities in Australia

© 2018 National Rural Health Alliance Ltd. Objective: To determine the impact of an integrated diabetes service involving specialist outreach and primary health care teams on risk factors for micro- and macrovascular diabetes complications in three remote Indigenous Australian communities over a 12-month period. Design: Quantitative, retrospective evaluation. Setting: Primary health care clinics in remote Indigenous communities in Australia. Participants: One-hundred-and-twenty-four adults (including 123 Indigenous Australians; 76.6% female) with diabetes living in remote communities. Main outcome measures: Glycosylated haemoglobin, lipid profile, estimated glomerular filtration rate, urinary albumin : creatinine ratio and blood pressure. Results: Diabetes prevalence in the three communities was high, at 32.8%. A total of 124 patients reviewed by the outreach service had a median consultation rate of 1.0 by an endocrinologist and 0.9 by a diabetes nurse educator over the 12-month period. Diabetes care plans were made in collaboration with local primary health care services, which also provided patients with diabetes care between outreach team visits. A significant reduction was seen in median (interquartile range) glycosylated haemoglobin from baseline to 12 months. Median (interquartile range) total cholesterol was also reduced. The number of patients prescribed glucagon-like peptide-1 analogues and dipeptidyl peptidase-4 inhibitors increased over the 12 months and an increase in the number of patients prescribed insulin trended towards statistical significance. Conclusion: A collaborative health care approach to deliver diabetes care to remote Indigenous Australian communities was associated with an improvement in glycosylated haemoglobin and total cholesterol, both important risk factors, respectively, for micro- and macrovascular diabetes complications

QUANTITATIVE ANALYSIS OF PIGMENT EPITHELIAL DETACHMENT RESPONSE TO DIFFERENT ANTI-VASCULAR ENDOTHELIAL GROWTH FACTOR AGENTS IN WET AGE-RELATED MACULAR DEGENERATION

Purpose: To assess whether best-corrected visual acuity and pigment epithelial detachment (PED) height, volume, and reflectivity in patients with wet age-related macular degeneration are influenced by baseline anatomical and functional parameters, including quantifiable metrics of PED morphology and choice of treatment. Methods: One hundred two consecutive, treatment-naive wet age-related macular degeneration patients with PED (>50 μm) treated with aflibercept (52) or ranibizumab (50) were retrospectively included. Pigment epithelial detachment height, horizontal and vertical dimensions, and volume were recorded at baseline, 3 months, and 1 year, respectively. Bespoke image analysis software provided a quantifiable measure of reflectivity. Results: Best-corrected visual acuity at 3 months was influenced by baseline best-corrected visual acuity (P = 0.006). Pigment epithelial detachment height was influenced by baseline height (P = 0.009), subretinal fluid (P = 0.008), central macular thickness (P = 0.006), and use of aflibercept (P = 0.003) at 3 months and by baseline height (P = 0.018), volume (P = 0.017), vertical dimension (P = 0.0004), and aflibercept (P = 0.015) at 1 year. Pigment epithelial detachment reflectivity increased from 43.59 to 55.86 (3 months) and 57.35 (1 year) (P < 0.001) and was influenced by its baseline values and, interestingly, use of aflibercept at 3 months (P = 0.013). Conclusion: Quantifiable metrics of PED morphology improve with treatment, and PED content becomes hyperreflective, more so on aflibercept. Pigment epithelial detachments respond better in the context of more active disease. More hyporeflective PED content may predispose to better treatment response, especially with aflibercept

Dietary factors are not associated with high levels of obesity in New Zealand Pacific preschool children.

Pacific children living in New Zealand (NZ) are prone to excessive weight gain. In this study, we assessed the anthropometric status of 2- to 5-y-old Pacific children (n = 60) in relation to their macronutrient intakes. Measurements of height (n = 56), weight (n = 60), midarm circumference, and triceps skinfold thickness (n = 58), and 2-d weighed food records (n = 60) and demographic data were collected. Z-score results (mean +/- SD) showed that these children were tall (0.61 +/- 1.1) and heavy (1.67 +/- 1.1) for their age, and had high arm-muscle-area-for-height (geometric mean, 2.05). Over 64 and 45% of children were classified as overweight (including obesity) and obese, respectively. The percentage of energy contributed by fat in their diets met recommendations. In contrast, the percentage of energy contributed by sugar was high. The macronutrient intakes of children classified as obese (n = 32) compared with non-obese (n = 24) did not differ; however, their adjusted energy intakes were higher [5.79 (1.4) vs. 4.97 (1.4) MJ/d; P = 0.01]. Overweight and obesity were very common among very young NZ Pacific children, although the dietary etiology was not elucidated. These results emphasize the urgent need for obesity prevention for NZ Pacific children that begins early in life to avoid a future public health crisis
