Real‐time continuous glucose monitoring (rtCGM) and intermittently scanned CGM (isCGM) have both been shown to improve glycaemic outcomes in people with T1D. The aim of this study was to compare real‐world glycaemic outcomes at 6–12 months in a propensity score matched cohort of CGM naïve adults with T1D who initiated a rtCGM or an isCGM. Among the matched rtCGM and isCGM cohorts (n = 143/cohort), rtCGM users had a significantly greater HbA1c benefit compared to isCGM users (adjusted difference, −3 mmol/mol [95% CI, −5 to −1]; −0.3% [95% CI, −0.5 to −0.1]; p = 0.01). There was a significantly greater lowering of HbA1c for rtCGM compared to isCGM when baseline HbA1c was <69 mmol/mol (8.5%) (adjusted difference, −4 mmol/mol [95% CI, −7 mmol/mol to −2 mmol/mol]; −0.4% [95% CI, −0.6% to −0.2%]; p < 0.001), and in MDI users (adjusted difference, −3 mmol/mol [95% CI, −6 mmol/mol to −0 mmol/mol]; −0.3% [95% CI ‐0.5% to 0.0%], p = 0.04). The rtCGM cohort had significantly greater time in range (58.3 ± 16.1% vs. 54.5 ± 17.1%, p = 0.03), lower time below range (2.1 ± 2.7% vs. 6.1 ± 5.0%, p < 0.001) and lower glycaemic variability compared to the isCGM cohort. In this real‐world analysis of adults with T1D, rtCGM users had a significantly greater reduction in HbA1c at 6–12 months compared to isCGM, and significantly greater time in range, lower time below range and lower glycaemic variability, compared to a matched cohort of isCGM users.

Objective: Clinical guidelines now define the standard of diabetes care, but few health care jurisdictions systematically assess their practicality and impact. The Canadian LMC Diabetes Registry includes the electronic health records of >50 endocrinologists in three provinces and provides quarterly real-time outcome reports to each endocrinologist. This retrospective cohort study aimed to characterize the demographics, treatment regimens, and outcomes of the type 1 diabetes (T1D) patient population in the registry. Research Design and Methods: Adults were included if they had a clinical diagnosis of T1D, had seen an LMC endocrinologist between July 1, 2015 and June 30, 2018, and had follow-up >6 months. This study is registered on clinicaltrials.gov (NCT04162067). Results: The resulting cohort included 3600 individuals with mean age of 43.9 ± 15.3 years and duration of diabetes of 21.5 ± 13.9 years. Mean hemoglobin A1C (HbA1c) was 8.1% ± 1.5% and only 22.5% had achieved HbA1c ≤7.0%. In each measure, individuals in younger cohorts showed poorer glycemic control than older cohorts. Within each age cohort, insulin pump users showed a lower mean HbA1c than those using multiple daily injections, especially in cohorts who were also not using a continuous glucose monitor. Overall, 63.1% reported at least weekly hypoglycemia, whereas 3.6% reported severe hypoglycemia ≥1 per year. Conclusions: Despite receiving care in an advanced well-resourced environment, within a public health care system, from specialists armed with regular patient outcomes feedback, most individuals with T1D are unable to achieve the goals recommended by clinical practice guidelines.

Objective: Postexercise hyperglycemia, following high-intensity interval training (HIIT) in patients with type 1 diabetes (T1D), is largely underrecognized by the clinical community and generally undertreated. The aim of this study was to compare four multipliers of an individual's insulin correction factor (ICF) to treat post-HIIT hyperglycemia.Research Design and Methods: The FIT study had a randomized, crossover design in physically active subjects with T1D (mean ± SD age 34.9 ± 10.1 years, BMI 25.5 ± 2.5 kg/m2, and HbA1c 7.2 ± 0.9%) using multiple daily injections. Following an 8-week optimization period, with 300 units/mL insulin glargine used as the basal insulin, subjects performed four weekly sessions of 25 min of HIIT. If hyperglycemia (>8.0 mmol/L) resulted, subjects received a bolus insulin correction 15 min post-HIIT, based on their own ICF, adjusted by one of four multipliers: 0, 50, 100, or 150%.Results: Seventeen subjects completed 71 exercise trials, of which 64 (90%) resulted in hyperglycemia. At 40 min postexercise, plasma glucose (PG) increased from mean ± SD 8.8 ± 1.0 mmol/L at baseline to 12.7 ± 2.4 mmol/L (increase of 3.8 ± 1.5 mmol/L). After correction, adjusted mean ± SE PG was significantly reduced for the 50% (-2.3 ± 0.8 mmol/L, P < 0.01), 100% (-4.7 ± 0.8 mmol/L, P < 0.001), and 150% (-5.3 ± 0.8 mmol/L, P < 0.001) arms but had increased further in the 0% correction arm. Both the 100 and 150% corrections were more effective than the 50% correction (P < 0.01 and P < 0.001, respectively) but were not different from each other. Hypoglycemia was rare.Conclusions: In post-HIIT hyperglycemia, correction based on a patient's usual ICF is safe and effective. Optimal PG reduction, with minimal hypoglycemia, occurred in the 100 and 150% correction arms. [ABSTRACT FROM AUTHOR]

Background: Optimal diabetes care requires a specific set of self-management behaviours. The purpose of this study was to present the development and initial psychometric evaluation of a new tool to measure three key aspects of a patient's diabetes self-management: knowledge of the skill, confidence in being able to perform the skill and preparedness to implement the skill.Methods: A sequential exploratory mixed-methods design was used. A panel of educators, researchers and clinicians established a scale with items that would adequately capture skills, confidence and preparedness in seven core health behaviours central to diabetes care. The psychometric properties of the items were pilot tested on 120 participants with diabetes from a tertiary referral centre, and repeated 6 months later on 70 participants. Item selection was informed by factor analysis, item-total statistics and the need for brevity.Results: Twenty five items from a pool of 36 were retained, with an excellent overall intraclass correlation (ICC) of 0.94 (95% CI 0.92-0.99; p < 0.001). Internal consistency for the subscales (skills-9 items, confidence - 8 items, preparedness - 8 items) was very good (intraclass correlation between 0.83 and 0.88), and retest reliability after 6 months was also good (r = 0.48; p < 0.01). The scale was positively correlated to established scales that assess skill (Michigan Diabetes Knowledge Test) (r = 0.21;p = 0.01), and assess skill and confidence (Diabetes Empowerment Scale) (r = 0.28;p < 0.01).Conclusions: The Skills, Confidence & Preparedness Index is a brief and easy to administer new scale that is more comprehensive than existing tools. It should be used to assess self-management in patients with diabetes, optimize the resources applied to each patient, and determine educational needs and direct clinical management. The scale should be further evaluated in a broader population of patients with diabetes. [ABSTRACT FROM AUTHOR]

Background: The aim was to assess the cost impact of daptomycin compared to vancomycin treatment in patients hospitalised for complicated skin and soft-tissue infection (cSSTI) with suspected methicillin-resistant Staphylococcus aureus infection in the UK. Methods: A decision model was developed to estimate the costs associated with cSSTI treatment. Data on efficacy, treatment duration and early discharge from published clinical trials were used, with data gaps on standard clinical practice being filled by means of clinician interviews. Results: Total health-care costs per patient were GBP 6,214 and GBP 6,491 for daptomycin and vancomycin, respectively. A sensitivity analysis suggested that modifying the parameters within a reasonable range does not impact on the conclusion that the higher cost of daptomycin is likely to be offset by lower costs of monitoring and hospitalisation. Conclusions: This study demonstrates that daptomycin not only provides an alternative treatment for multiple resistant infections, but may also reduce National Health Service costs. © 2014 S.

Aims: This study determined the joint association between physical activity, pharmacotherapy, and HbA1c control on all-cause and cardiovascular disease (CVD) mortality risk in adults with and without type 2 diabetes (T2D). Methods: 12,060 adults from NHANES III and NHANES continuous (1999–2002) surveys were used. Cox proportional hazards analyses were included to estimate mortality risk according to physical activity, pharmacotherapy, and glycemic control (HbA1c b7.0%) status, with physically active, treated and controlled (goal situation) as the referent. Results: Compared to the referent, adults with T2D who were uncontrolled, or controlled but physically inactive had a higher all-cause mortality risk (p b 0.05). Compared to the referent, only adults with T2D who were physically inactive had a higher CVD mortality risk, regardless of treatment or control status (p b 0.05). Normoglycemic adults had a similar all-cause and CVD mortality risk as the referent (p N 0.05). Conclusions: Physical activity and glycemic control are both associated with lower all-cause and CVD mortality risk in adults with T2D. Adults with T2D who are physically active, pharmacologically treated, and obtain glycemic control may attain similar mortality risk as normoglycemic adults. [ABSTRACT FROM AUTHOR]

The purpose of this study was to examine force steadiness in three positions of the forearm in young men and women across a variety of force levels. Eight young men and eight young women performed three maximum voluntary contractions (MVCs) in the neutral, supinated, and pronated forearm positions. Viewing a target line on a computer screen, subjects performed submaximal isometric contractions relative to their own MVC at 2.5, 5, 10, 25, 50, and 75% in each of the three forearm positions. Force steadiness was determined as the coefficient of variation (standard deviation around the mean force). A repeated-measures three-way ANOVA was used to assess the differences in force steadiness between sex, position, and force level. Men were stronger than women in all three forearm positions. Overall, men were steadier than women across all force levels and forearm positions. The neutral and supinated positions were equally strong and steady, and the pronated position was the weakest and least steady position. The forearm was most steady between 25 and 75% MVC, and least steady at the lower force levels. When correlations were run between MVC and coefficient of variation at all force levels and all forearm positions, a strong negative relationship was found (r = -0.49). In conclusion, men were stronger, as well as steadier, than women. The neutral and supinated forearm positions were both stronger and steadier than the pronated position. Results suggest that one of the primary factors influencing sex differences in force steadiness is absolute strength. [ABSTRACT FROM AUTHOR]

Aims: Patients with type 1 diabetes (T1D) often report a rise in their blood glucose level following brief intense exercise. We sought to determine the reproducibility of the cardiometabolic responses to high-intensity interval training (HIIT).Methods: Sixteen adults with T1D, using an optimized multiple daily injection with basal insulin glargine 300 U/mL (Gla-300), performed four fasted HIIT sessions over a 4-6-week period. Exercise consisted of high-intensity interval cycling and multimodal training over 25 min.Results: Heart rate and rating of perceived exertion rose similarly in all sessions, as did lactate, catecholamine and growth hormone levels. Plasma glucose increased in response to HIIT in 62 of 64 visits (97%), with an overall increase of 3.7 ± 1.6 mmol/L (Mean ± SD) (P < 0.001). In within-patient comparisons, the change in plasma glucose among the four HIIT sessions was significantly correlated with a composite correlation of 0.58 ([r2 = 0.34]; 95% CI 0.35-0.80; P < 0.01).Conclusions: Intersession observations of four separate HIIT sessions showed high intrasubject reproducibility in the cardiometabolic responses to exercise, including the rise in plasma glucose, when adults with T1D perform the activity in a fasted state.
