Evolving Trends in the Management of Diabetic Foot Ulcers: A Narrative Review.

The prevalence of diabetic foot ulcers (DFUs) is projected to increase worldwide, which necessitates a review of the current management principles and the development of new approaches to care. The principles of management involve proper glycemic control, infection control, pressure redistribution, wound care debridement, and revascularization. Other modalities of management, such as hyperbaric oxygen therapy and negative wound pressure therapy, are also being explored. While some aspects of DFU care lack high-quality evidence, a multidisciplinary approach incorporating these evolving trends has the potential to improve outcomes and prevent lower extremity amputations in this challenging condition. This review highlights the need for further research to establish definitive treatment protocols for optimal DFU management.

Neighbourhood Environments and Lifestyle Behaviours in Adolescents With Type 1 Diabetes.

OBJECTIVES: Early prevention strategies are needed to mitigate the high risk of cardiovascular disease in adolescents with type 1 diabetes (T1D). Residential neighbourhood features can promote healthy lifestyle behaviours and reduce cardiovascular risk, but less is known about their role in lifestyle behaviours in adolescents with T1D, and no studies used comparisons to healthy controls. METHODS: We examined associations between residential neighbourhood features and lifestyle behaviours in adolescents with T1D and healthy controls. Data were analyzed from the CARdiovascular Disease risk factors in pEdiatric type 1 diAbetes (CARDEA) study, a cross-sectional investigation of 100 adolescents with T1D (14 to 18 years) from a pediatric diabetes clinic in Montréal, Canada, and 97 healthy controls. Outcomes included physical activity and sedentary behaviour (accelerometry), screen time and sleep duration (questionnaires), and dietary habits (24-hour recalls). Cluster analysis of selected neighbourhood indicators computed for participants' postal codes resulted in 2 neighbourhood types: central urban and peri-urban. Central urban neighbourhoods were characterized by very high population density, high active living index, numerous points of interest, higher social deprivation, higher residential mobility, and lower median household income compared with peri-urban neighbourhoods. Associations of neighbourhood type with lifestyle behaviours were estimated with multiple linear regressions and interactions by T1D status were tested. RESULTS: Living in central urban neighbourhoods was associated with greater daily minutes of moderate-to-vigourous physical activity (beta = 8.61, 95% confidence interval 1.79 to 15.44) compared with living in peri-urban neighbourhoods. No associations were observed for other lifestyle behaviours, and no statistically significant interactions were found between neighbourhood type and T1D status. CONCLUSION: Features that characterize central urban built environments appear to promote physical activity in adolescents, regardless of T1D status.

Factors Influencing Physical Activity Level in Adults With Type 1 Diabetes: A Cross-sectional Study.

OBJECTIVES: Exercise is a recommended component of type 1 diabetes (T1D) treatment because high physical activity levels improve health outcomes. However, many people with T1D do not meet physical activity recommendations. Our aim in this study was to identify factors influencing physical activity levels in people with T1D. METHODS: This questionnaire-based study included adults with T1D from 1 outpatient clinic in the United Kingdom and 2 clinics in Denmark. Exercise characteristics, motivators, and barriers were assessed. Physical activity level was measured using the Saltin-Grimby Physical Activity Level Scale. Respondents were categorized into 3 activity groups: inactive, light active, and moderate-to-vigourous active. RESULTS: Of the 332 respondents, 8.4% rated themselves as inactive, 48% as light active, and 43% as moderate-to-vigourous active. Seventy-eight percent of inactive and light active repondents expressed a desire to become more physically active. Fifty-three percent of respondents had received guidance concerning exercise/physical activity from their diabetes team. Being male and having received guidance were associated with a higher physical activity level. The major motivators for exercising/being physically active were improved mental and physical health and glycemic control, whereas the most frequent barriers were busyness with work/private life and lack of motivation. Worries about glucose excursions, costs, lack of knowledge, and health-related reasons were more prevalent barriers in the least active groups. CONCLUSIONS: This study demonstrated that 78% of inactive and light active respondents reported wishing to become more physically active. Receiving guidance about exercise/physical activity was associated with a higher physical activity level, but only 53% of respondents had received support from their diabetes team.

Changing Glucose Levels During the Menstrual Cycle as Observed in Adults in the Type 1 Diabetes Exercise Initiative Study.

OBJECTIVES: Evidence suggests that glucose levels in menstruating females with type 1 diabetes change throughout the menstrual cycle, reaching a peak during the luteal phase. The Type 1 Diabetes Exercise Initiative (T1DEXI) study provided the opportunity to assess glycemic metrics between early and late phases of the menstrual cycle, and whether differences could be explained by exercise, insulin, and carbohydrate intake. METHODS: One hundred seventy-nine women were included in our analysis. Glycemic metrics, carbohydrate intake, insulin requirements, and exercise habits during the early vs late phases of their menstrual cycles (i.e. 2 to 4 days after vs 2 to 4 days before reported menstruation start date) were compared. RESULTS: Mean glucose increased from 8.2±1.5 mmol/L (148±27 mg/dL) during the early follicular phase to 8.6±1.6 mmol/L (155±29 mg/dL) during the late luteal phase (p<0.001). Mean percent time-in-range (3.9 to 10.0 mmol/L [70 to 180 mg/dL]) decreased from 73±17% to 70±18% (p=0.002), and median percent time >10.0 mmol/L (>180 mg/dL) increased from 21% to 23% (p<0.001). Median total daily insulin requirements increased from 37.4 units during the early follicular phase to 38.5 units during the late luteal phase (p=0.02) and mean daily carbohydrate consumption increased slightly from 127±47 g to 133±47 g (p=0.05); however, the difference in mean glucose during early follicular vs late luteal phase was not explained by differences in exercise duration, total daily insulin units, or reported carbohydrate intake. CONCLUSIONS: Glucose levels during the late luteal phase were higher than those of the early follicular phase of the menstrual cycle. These glycemic changes suggest that glucose management for women with type 1 diabetes may need to be fine-tuned within the context of their menstrual cycles.

Prognostic Implications of Diabetic Ketoacidosis in Adults on Long-term Mortality and Diabetes-related Complications.

OBJECTIVES: Diabetic ketoacidosis (DKA) occurring after diabetes diagnosis is often associated with risk factors for other diabetes-related complications. In this study we aimed to determine the prognostic implications of DKA on all-cause mortality and complications in type 1 diabetes (T1D). METHODS: Previously collected data from the Diabetes Control and Complications Trial/Epidemiology of Diabetes Interventions and Complications (DCCT/EDIC) study were obtained through the the National Institute of Diabetes and Digestive and Kidney Diseases Central Repository. Using Cox proportional hazards models with time-dependent covariates, we examined age- and sex-adjusted, glycated hemoglobin-adjusted, and fully adjusted associations of DKA with all-cause mortality, cardiovascular disease, microvascular, and acute complications over 34 years. RESULTS: Of the 1,441 study participants, 297 had 488 DKA events. Prior DKA was associated with a higher risk of age- and sex-adjusted all-cause mortality (hazard ratio [HR] 8.28, 95% confidence interval [CI] 3.74 to 18.32, p<0.001), major adverse cardiovascular events (MACEs) (HR 2.05, 95% CI 1.34 to 3.13, p<0.001), and all advanced microvascular and acute complications compared with no prior DKA. Most associations except retinopathy were significant even after adjustment for covariates. In our fully adjusted analysis, prior DKA was associated with a significantly higher risk of subsequent all-cause mortality (HR 9.13, 95% CI 3.87 to 21.50, p<0.001), MACEs (HR 1.66, 95% CI 1.07 to 2.59, p=0.03), advanced kidney disease (HR 2.10, 95% CI 1.00 to 4.22, p=0.049), advanced neuropathy (HR 1.49, 95% CI 1.05 to 2.13, p=0.03), severe hypoglycemia (HR 1.53, 95% CI 1.28 to 1.81, p<0.001), and recurrent DKA (HR 3.24, 95% CI 2.41 to 4.36, p<0.001) compared with person-time without DKA. CONCLUSIONS: DKA is a prognostic marker for diabetes complications, including excess all-cause mortality. Intensified clinical interventions, such as cardiovascular prevention strategies, may be warranted after diagnosis of DKA.

Impact of Time of Day on Glycemia in Response to Postprandial Supramaximal Sprints in Adults With Type 1 Diabetes.

OBJECTIVES: In this study we explore the impact of postprandial exercise timing (morning vs evening) on glycemia in individuals with type 1 diabetes (T1D) during short all-out sprints on a cycle ergometer. METHODS: Ten healthy physically sedentary male (n=7) and female (n=3) volunteers with type 1 diabetes, 22.8±2.8 years of age, and with a diabetes duration of 9.7±5.5 years and glycated hemoglobin level of 8.6±1.2%, underwent comprehensive screening and assessment of their physical health and fitness status before study participation, under the guidance of a physician. Each participant underwent 2 postprandial exercise sessions on separate days: the first in the morning at 8:00 AM and second in the evening at 8:00 PM, both conducted 60 minutes after a standardized meal. RESULTS: Morning exercise showed a less pronounced reduction in plasma glucose (PG) levels compared with evening exercise (-2.01±1.24 vs -3.56±1.6 mmol/L, p=0.03). In addition, higher cortisol levels were observed in the morning vs evening (128.59±34 vs 67.79±26 ng/mL, p<0.001). CONCLUSIONS: Morning repeated sprint exercise conducted in the postprandial state consistent with the protective effect of higher cortisol levels resulted in a smaller reduction in PG levels compared with evening exercise. This highlights the potential influence of exercise timing on glycemic responses and cortisol secretion in the management of T1D.

Prescription Patterns of Sodium-glucose Cotransporter-2 Inhibitors in Adults With Type 2 Diabetes and Heart Failure With Reduced Ejection Fracture Admitted to a Tertiary Care Centre in Ontario, Canada.

OBJECTIVES: Our aim in this study was to assess early adoption patterns of sodium-glucose cotransporter-2 inhibitors (SGLT2i) in eligible patients with type 2 diabetes (T2DM) and heart failure with reduced ejection fracture (HFrEF), and to identify gaps in practice. METHODS: A retrospective chart review was conducted of patients with T2DM and HFrEF admitted with decompensated heart failure to The Ottawa Hospital under cardiology or general internal medicine from June 2019 to May 2021. Patterns were assessed at 8-month intervals (1 period before release of the Diabetes Canada 2020 guidelines and 2 periods afterward). Baseline patient characteristics, comorbidities, and prescriber information were collected. RESULTS: Of the 98 patients who met the inclusion criteria, 36.7% had a prescription for an SGLT2i, either on admission, discharge, or follow-up. Trends showed a gradual increase over time. On admission, 9.8% of patients were on an SGLT2i in period 1, 19.2% in period 2, and 23.3% in period 3. Patients receiving a prescription for SGLT2i on discharge were 0.0% in period 1, 10.0% in period 2, and 9.5% in period 3, all of whom were admitted under cardiology. On follow-up, 13.9% of eligible patients were started on an SGLT2i in period 1, 21.1% in period 2, and 35.0% in period 3. Endocrinology was the main prescriber of SGLT2i in the outpatient setting, followed by cardiology. CONCLUSIONS: Overall, trends show a slow but steady increase in early prescriptions of SGLT2i. However, most eligible patients were not started on therapy during our study period with variability in practice between specialties, highlighting opportunities to boost uptake in the future.

Is stimulation of browning of human adipose tissue a relevant therapeutic target?

Brown adipose tissue (BAT) and beige adipose tissues are important contributors to cold-induced whole body thermogenesis in rodents. The documentation in humans of cold- and ß-adrenergic receptor agonist-stimulated BAT glucose uptake using positron emission tomography (PET) and of a decrease of this response in individuals with cardiometabolic disorders led to the suggestion that BAT/beige adipose tissues could be relevant targets for prevention and treatment of these conditions. In this brief review, we will critically assess this question by first describing the basic rationale for this affirmation, second by examining the evidence in human studies, and third by discussing the possible means to activate the thermogenic response of these tissues in humans.

Partial lipodystrophy: Clinical presentation and treatment.

Lipodystrophic syndromes are acquired or genetic rare diseases, characterized by a generalized or partial lack of adipose tissue leading to metabolic alterations linked to strong insulin resistance. They are probably underdiagnosed, especially for partial forms. They are characterized by a lack of adipose tissue or a lack of adipose development leading to metabolic disorders associated with often severe insulin resistance, hypertriglyceridemia and hepatic steatosis. In partial forms of lipodystrophy, these mechanisms are aggravated by excess visceral adipose tissue and/or subcutaneous adipose tissue in the upper part of the body. Diagnosis is based on clinical examination, pathological context and comorbidities, and on results of metabolic investigations and genetic analyses, which together determine management and genetic counseling. Early lifestyle and dietary measures focusing on regular physical activity, and balanced diet avoiding excess energy intake are crucial. They are accompanied by multidisciplinary follow-up adapted to each clinical form. When standard treatments have failed to control metabolic disorders, the orphan drug metreleptin, an analog of leptin, can be effective in certain forms of lipodystrophy syndromes.

The Impact of Gender on Physical Activity Preferences and Barriers in Adults With Type 1 Diabetes: A Qualitative Study.

OBJECTIVES: Current exercise recommendations for people with type 1 diabetes (T1D) are based on research involving primarily young, fit male participants. Recent studies have shown possible differences between male and female blood glucose response to exercise, but little is known about whether these differences are sex-related (due to physiological differences between male and female participants) or gender-related (behavioural differences between men and women). METHODS: To better understand gender-based behavioural differences surrounding physical activity (PA), we asked men and women (n=10 each) with T1D to participate in semistructured interviews. Topics discussed included motivation and barriers to exercise, diabetes management strategies, and PA preferences (type, frequency, duration of exercise, etc). Interview transcripts were coded by 2 analysts before being grouped into themes. RESULTS: Six themes were identified impacting participants' PA experience: motivation, fear of hypoglycemia, time lost to T1D management, medical support for PA, the role of technology in PA accessibility, and desire for more community. Gender differences were found in motivations, medical support, and desire for more community. Women were more motivated by directional weight dissatisfaction, and men were more motivated to stay in shape. Men felt less supported by their health-care providers than women. Women more often preferred to exercise in groups, and sought more community surrounding T1D and PA. CONCLUSION: Although men and women with T1D experience similar barriers around PA, there are differences in motivation, desire for community, and perceived support from medical providers.

[Acute coronary syndromes in diabetes mellitus : A comparative study between diabetics and non-diabetics patients in Senegalese urban environment]. / Syndromes coronaires aigus au cours du diabète : étude comparative entre patients diabétiques et non diabétiques en milieu urbain sénégalais.

INTRODUCTION: Diabetes Mellitus is a strong cardiovascular risk factor in which acute coronary syndromes (ACS) are thought to have a particular feature. We aimed to determine the characteristics of acute coronary syndromes in diabetics compared with non-diabetics patients. PATIENTS AND METHODS: We carried out a prospective, descriptive and analytical study comparing diabetic and non-diabetic patients admitted for acute coronary syndrome to the cardiology department of Idrissa Pouye general hospital over a period of one year by studying socio-demographic, clinical, paraclinical, therapeutic and evolutionary parameters. We performed a multivariable logistic regression analysis to identify factors associated with chest pain and triple vessels disease. RESULTS: Our study included 139 patients, 61 with diabetes (44%) and 78 without diabetes (56%). Among diabetics, there was a predominance of women (p = 0.0001) in contrast to non-diabetics. The mean age was 62.7 ± 10.8 years in diabetics and 56.9 ± 13.5 years in non-diabetics (p = 0.006). Chest pain was found in 88.5% of diabetics and 97.4% of non-diabetics (p = 0.03). The mean HbA1c in diabetics was 9.4 ± 3.3%. ST elevation acute coronary syndrome was predominant in both groups. The mean GRACE score was 147 ± 29 in diabetics and 132 ± 28 in non-diabetics (p = 0.003). In multivariable analysis, only diabetes was associated with triple vessels disease (aOR (IC à 95%): 2,60 (1.29-6.83); p = 0.042). A total of 31% of diabetics and 43% of nondiabetics undergoes cardiac revascularization. There was no difference between the two groups in terms of complications. The mortality was 6.6% and 3.8% respectively among diabetics and non-diabetics (p = 0.49). CONCLUSION: According to our study, diabetes is frequently encountered during acute coronary syndromes. It also shows that diabetics are more likely to be female and older, with more atypical symptoms and more severe coronary disease.

[Clinical profile of corneal sensitivity in diabetic patients: A case-control study]. / Profil clinique de la sensibilité cornéenne chez les patients diabétiques : étude cas-témoins.

PURPOSE: To evaluate the corneal sensitivity of black diabetic patients and identify factors associated with changes in corneal sensitivity. METHODOLOGY: We conducted a cross-sectional comparative case-control study at the National Obesity Center of the Yaounde Central Hospital and the Djoungolo District Hospital from March 1 to July 31, 2022. Corneal sensitivity was measured using the Cochet-Bonnet esthesiometer in all diabetic patients over 18 years of age, matched for age and sex to a clinically healthy control population. Data were analyzed using SPSS version 23.0 software. A P-value of less than 5% was considered significant. RESULTS: A total of 111 diabetic and 111 non-diabetic patients participated in the study. The mean age was 53.46±12.74 years for diabetics and 52.85±11.77 years for non-diabetics (P=0.901). The mean duration of diabetes was 6.4±5.30 years. Corneal sensitivity in diabetics was lower (44.56±9.59mm) compared to non-diabetics (53.59±6.30mm) with a statistically significant difference (P=0.000). Factors associated with decrease in corneal sensitivity in diabetics were duration of diabetes and poor glycemic control. CONCLUSION: Decrease in corneal sensitivity related to diabetes is a complication to be systematically screened for during the ophthalmologic follow-up of diabetic patients.

Basal Insulin Initiation in Adults With Type 2 Diabetes Mellitus: A Retrospective Cohort Study Using Administrative Health Data in Alberta, Canada.

OBJECTIVES: Pharmacologic treatment of type 2 diabetes mellitus (T2DM) follows a stepwise approach. Typically, metformin monotherapy is first-line treatment, followed by other noninsulin antihyperglycemic agents (NIAHAs) or progression to insulin if glycated hemoglobin (A1C) targets are not achieved. We aimed to describe real-world patterns of basal insulin initiation in people with T2DM and A1C not at target despite treatment with at least 2 NIAHAs. METHODS: A retrospective cohort study was conducted using administrative health data from Alberta, Canada, among adults with T2DM, indexed on the first test with 7.0% < A1C < 9.5% (April 1, 2011, to March 31, 2019), with at least 2 previous NIAHAs but no insulin. Kaplan-Meier (KM) methodology was used to analyze time to basal insulin initiation, with stratification by index A1C. Annual patient status was categorized into 5 groups: basal insulin initiation, death, NIAHA intensification, no change in therapy (subgroups of A1C <7.1% and A1C ≥7.1% [clinical inertia]), or discontinuance. RESULTS: The cohort included 14,083 individuals. The KM cumulative probability of initiating basal insulin was 7.7% (95% confidence interval [CI] 7.3% to 8.2%) at 1 year, increasing to 43.1% (95% CI 42.1% to 44.1%) at 8 years of follow-up. Higher A1C levels were associated with greater proportions of basal insulin initiation. By year 8, proportions with NIAHA intensification and clinical inertia were 12.1% and 19.3%, respectively, relative to year 7. CONCLUSIONS: Despite current clinical practice guidelines recommending achieving A1C targets within 6 months, less than half of the individuals with T2DM and clear indications for basal insulin initiated treatment within 8 years. Efforts to reduce delays in basal insulin initiation are needed.

An Aerobic Cooldown After Morning, Fasted Resistance Exercise Has Limited Impact on Post-exercise Hyperglycemia in Adults With Type 1 Diabetes: A Randomized Crossover Study.

OBJECTIVES: Expert guidelines recommend an aerobic cooldown to lower blood glucose for the management of post-exercise hyperglycemia. This strategy has never been empirically tested. Our aim in this study was to compare the glycemic effects of performing an aerobic cooldown vs not performing a cooldown after a fasted resistance exercise session. We hypothesized that the cooldown would lower blood glucose in the 30 minutes after exercise and would result in less time in hyperglycemia in the 6 hours after exercise. METHODS: Participants completed 2 identical resistance exercise sessions. One was followed by a low-intensity (30% of peak oxygen consumption) 10-minute cycle ergometer cooldown, and the other was followed by 10 minutes of sitting. We compared the changes in capillary glucose concentration during these sessions and continuous glucose monitoring (CGM) outcomes over 24 hours post-exercise. RESULTS: Sixteen participants completed the trial. Capillary glucose was similar between conditions at the start of exercise (p=0.07). Capillary glucose concentration decreased by 0.6±1.0 mmol/L during the 10-minute cooldown, but it increased by 0.7±1.3 mmol/L during the same time in the no-cooldown condition. The resulting difference in glucose trajectory led to a significant interaction (p=0.02), with no effect from treatment (p=0.7). Capillary glucose values at the end of recovery were similar between conditions (p>0.05). There were no significant differences in CGM outcomes. CONCLUSIONS: An aerobic cooldown reduces glucose concentration in the post-exercise period, but the small and brief nature of this reduction makes this strategy unlikely to be an effective treatment for hyperglycemia occurring after fasted exercise.

Glycemic and lipid control in patients with diabetes at time of myocardial infarction.

OBJECTIVE: Cardiovascular risk is increased in patients with diabetes. Little is known about glycemic and lipid control in patients with diabetes. We aimed to assess glycemic and lipid controls in patients with diabetes at time of their myocardial infarction. METHOD: All known patients with type 2 diabetes consecutively admitted for a myocardial infarction in our coronary care unit between March 1st and December 31st, 2021 were included in this retrospective study. Glycemic and lipid control was assessed through individualized target of glycated haemoglobin (HbA1c) and low-density lipoprotein cholesterol (LDL-c), respectively. At admission, the comprehensive list of chronic medications was obtained through medication reconciliation. RESULTS: This study included 112 patients with a median age of 72 years. Most of patients had an individualized target of HbA1c and LDL-c of 7.0% (67%) and 0.55g/L (96%), respectively. The rate of uncontrolled patients for HbA1c and LDL-c and both was 46%, 90%, and 42% respectively. The rate of patients with non-optimal glucose- and lipid-lowering medications in uncontrolled patients was 63% and 87%, respectively. The rate of inappropriate glucose- and lipid-lowering medications was 73% and 91%, respectively. CONCLUSION: We highlighted the poor glycemic and lipid control in high-risk CV patients. There is an urgent need to develop multidisciplinary approaches to optimize CV risk factors control to reduce myocardial infarction and strokes.

Are Guideline-concordant Processes of Care Consistent Across the Rural-Urban Continuum? A Retrospective Cohort Study of Adults Newly Treated for Type 2 Diabetes.

OBJECTIVES: Our aim in this study was to identify the association between place of residence (metropolitan, urban, rural) and guideline-concordant processes of care in the first year of type 2 diabetes management. METHODS: We conducted a retrospective cohort study of new metformin users between April 2015 and March 2020 in Alberta, Canada. Outcomes were identified as guideline-concordant processes of care through the review of clinical practice guidelines and published literature. Using multivariable logistic regression, the following outcomes were examined by place of residence: dispensation of a statin, angiotensin-converting enzyme inhibitor (ACEi) or angiotensin II receptor blocker (ARB), eye examination, glycated hemoglobin (A1C), cholesterol, and kidney function testing. RESULTS: Of 60,222 new metformin users, 67% resided in a metropolitan area, 10% in an urban area, and 23% in a rural area. After confounder adjustment, rural residents were less likely to have a statin dispensed (adjusted odds ratio [aOR] 0.83, 95% confidence interval [CI] 0.79 to 0.87) or undergo cholesterol testing (aOR 0.86, 95% CI 0.83 to 0.90) when compared with metropolitan residents. In contrast, rural residents were more likely to receive A1C and kidney function testing (aOR 1.14, 95% CI 1.08 to 1.21 and aOR 1.17, 95% CI 1.11 to 1.24, respectively). ACEi/ARB use and eye examinations were similar across place of residence. CONCLUSIONS: Processes of care varied by place of residence. Limited cholesterol management in rural areas is concerning because this may lead to increased cardiovascular outcomes.

Association of Fructosamine Levels With Glycemic Management in Children With Type 1 Diabetes as Determined by Continuous Glucose Monitoring: Results From the CGM TIME Trial.

OBJECTIVE: Our aim in this study was to determine the correlation between serum fructosamine and average blood glucose, as measured by continuous glucose monitoring (CGM) in children with type 1 diabetes. METHODS: Ninety-seven blood samples were collected from 70 participants in the Timing of Initiation of continuous glucose Monitoring in Established pediatric diabetes (CGM TIME) Trial. Each eligible participant had 3 weeks of CGM data with at least 60% CGM adherence before blood collection. Ordinary least-squares linear regression incorporating restricted cubic splines was used to determine the association between fructosamine levels and mean blood glucose. RESULTS: An association was found between fructosamine and mean blood glucose, with an F statistic of 9.543 (p<0.001). Data were used to create a formula and conversion chart for calculating mean blood glucose from fructosamine levels for clinical use. CONCLUSIONS: There is a complex relationship between average blood glucose, as determined by CGM and fructosamine. Fructosamine levels may be clinically useful for assessing short-term glycemic management when CGM is not available.

Incident Functional Limitations Among Older Adults With Diabetes During the COVID-19 Pandemic: An Analysis of Prospective Data From the Canadian Longitudinal Study on Aging.

OBJECTIVES: The objectives of this study were 1) to examine and compare changes in functional limitations during the COVID-19 pandemic among older adults with and without diabetes; and 2): to identify key risk factors associated with developing functional limitations among older adults with and without diabetes during the pandemic. METHODS: We analyzed data collected from the Canadian Longitudinal Study on Aging. The analysis was restricted to those with no functional limitations in the follow-up 1 wave (2015 to 2018) (final sample N=6,045). Regression models were used to describe associations between diabetes status and functional limitation outcomes. We conducted stratified analyses to evaluate whether these associations varied by sociodemographic indicators. We also predicted the probability of the development of ≥1 functional limitation among those with and without diabetes for various patient profiles. RESULTS: Older adults with diabetes were 1.28-fold (95% confidence interval 1.02 to 1.60) more likely to develop ≥1 functional limitation than older adults without diabetes after controlling for relevant sociodemographic and health covariates. Risk factors for incident functional limitations among older adults, both with and without diabetes, include increasing age, low socioeconomic status, obesity, multimorbidity, and physical inactivity. CONCLUSIONS: Our findings indicate that older adults with diabetes were at an increased risk of developing functional limitations during the pandemic when compared with older adults without diabetes, even when controlling for several key risk factors. Targetting modifiable risk factors, such as physical activity, may help to reduce the risk of functional limitations among older adults with diabetes.

"I Am the Last Priority": Factors Influencing Diabetes Management Among South Asian Caregivers in Peel Region, Ontario.

OBJECTIVE: In this study, we aimed to identify sociocultural and systemic factors influencing diabetes management among South Asian (SA) caregivers in Peel Region, Ontario. METHODS: Twenty-one semistructured interviews were conducted with SA caregivers using a qualitative descriptive design. Data were analyzed using thematic analysis and intersectionality analysis. RESULTS: Themes identified included 1) prioritizing family caregiving over diabetes self-management; 2) labour market impacts on diabetes self-management; and 3) challenges navigating Canadian health and social service systems. SA caregivers described social, economic, and systemic challenges impacting type 2 diabetes management. Systemic factors influencing diabetes management included discrimination and inequities in labour policies and lack of social and health resources funding. Recommendations by caregivers included whole-family, community-based, culturally tailored approaches to diabetes prevention and management strategies. CONCLUSIONS: Providing support with system navigation, encouraging family-based approaches, and addressing the social determinants of health could be beneficial for supporting SA families with diabetes management and prevention.

[Peripheral arterial disease in black African diabetics: epidemioclinical, ultrasonographic profile and determining factors]. / Artériopathie oblitérante des membres inférieurs chez le sujet diabétique noir africain : profil épidémioclinique, ultrasonographique et facteurs déterminants.

BACKGROUND: Diabetes can lead to micro and macro-angiopathies. The peripheral arterial disease (PAD) is a serious and an incapacitating disease. It is still under-estimated and under-treated throughout the world, particularly in sub-Saharan Africa. Doppler ultrasound, and in particular ankle brachial index (ABI), can be used to detect it. The aim was to determine the prevalence of PAD to study the clinical and ultrasonographic aspects and to identify the determining factors. PATIENTS AND METHODS: This was a descriptive and analytical study over a period of 5 years, including a total of 782 diabetic patients hospitalised in the diabetology department of the CHU la Reference Nationale. RESULTS: Among the 782 patients, 166 (21.2%) had an ABI < 0.9 reflected the PAD and 72 (9.2%) had an ABI > 1.3, suggestive of mediacalcosis. PAD of the lower limb was mild in 102 patients (61.4%), moderate in (26.3%) and severe in (12.3%). The mean age of the arteritic patients was 56.4 ± 10.2 years. Male gender predominated (59.6%) with a sex ratio of 1.6. All patients had type 2 diabetes (100%). The mean duration of diabetes was 13 ± 5.9 years. The majority of our patients with arterial disease had diabetes for at least 10 years (54.2%). The other cardiovascular in this population were obesity (45.2%), followed by hypertension and dyslipidaemia (32.5%). Diabetes was unbalanced (HbA ≥7%) in the majority of cases (75.3%). Clinically, the majority of patients had a trophic disorder (68%). Asymptomatic patients accounted for 24.6% of cases and those with intermittent claudication for 7.4%. Duplex doppler of the lower limbs showed that all patients with PAD had atheromatous lesions. The distal location was predominantly in the tibial arteries (54.8%). The determinants of PAD in this diabetic population were hypertension (p = 0.01) and obesity (p = 0.01). CONCLUSION: In our series, PAD was often discovered at an advanced stage, with a non-negligible prevalence. The determining factors found were hypertension and obesity. Screening and control of major cardiovascular risk factors is a priority in the management of this disease.
