Background: Older people consistently report a desire to remain at home. Beat It is a community-based exercise and lifestyle intervention that uses evidence-based strategies to assist older people with type 2 diabetes mellitus (T2DM) to improve physical and functional fitness, which are crucial to maintain independence. This follow up, real-world study assessed the efficacy of Beat It and whether older adults with T2DM were able to maintain improvements in physical activity, waist circumference and fitness one year post completion. Methods: We have previously reported methods and results of short-term outcomes of Beat It. This paper reports anthropometric measurements and physical fitness outcomes of Beat it at 12-months post program completion and compares them to validated standards of fitness required to retain physical independence. Results: Improvements that were observed post program were maintained at 12 months (n = 43). While the number of participants who met fitness standards increased post program, not all increases were maintained at 12 months. Conclusions: This study provides promising early evidence that an eight-week, twenty-hour community-based clinician-led exercise and lifestyle program can improve health outcomes in older adults with T2DM which were retained for at least a year after program completion.

During the first lockdown of the COVID-19 pandemic, people with type 1 diabetes (T1D) were worried, stressed, and experienced changes in their self-management practices. Studies found that many had difficulties managing their disease, while others showed improvements. Since the first lockdown, the virus and subsequent lockdowns have become a more regular part of everyday life. The present study investigated how the COVID-19 pandemic, one year after its outbreak, has affected self-management in people with T1D. The dataset consisted of seven semi-structured interviews with adults with T1D, which were interpreted using Antonovsky’s theory of Sense of Coherence (SOC). We found that the pandemic and the ensuing lockdowns had contributed to better self-management in people with T1D, as they had developed a strong SOC. Knowledge from healthcare professionals and their own experiences with the COVID-19 pandemic had caused them to experience stronger comprehensibility, which had been crucial to experiencing strong manageability, enabling them to make active choices to maintain good glycemic control. Furthermore, better opportunities and more motivation had allowed them to experience stronger meaningfulness regarding immersing themselves in their treatment. Our findings show that, during health crises, having a strong SOC is important for disease management among people with T1D. Full article

There are about 200 million people on the move in the world, and approximately 50% of them are women. There are no clear migration plans for women leaving as a result of persecution, war, famine, climatic disasters or moving away from contexts of external abuse and even intrafamily violence. Gender-related violence, to which women are exposed in cultural contexts characterized by a patriarchal social organization, is manifested through different ways including, but not limited to, early marriages and genital mutilation, with reproductive health already being seriously impaired at an early age. To this must be added the consideration that low-income countries are not able to deal with chronic degenerative diseases with a multidisciplinary approach such as diabetes. Fragile or non-existent health systems are not prepared for this need, which now affects a third of all deaths from this cause. Compared to Italian mothers, women from high-migration pressure countries had a higher risk of gestational diabetes; in addition, young women of Ethiopian ethnicity are more exposed to increased diabetes risk, in an age- and BMI-dependent way. Gender inequalities are also more evident in migrants for other non-communicable diseases besides diabetes. A major effort is needed in terms of training practitioners and reorganization of basic health services, making them competent in an intercultural sense. Health education of the population as a whole and of women specifically is also needed to contain risk behavior and prevent the early onset of metabolic syndromes in general and of type 2 diabetes in particular.

Introduction: Metabolic Syndrome (MS) is a pathologic condition characterized by Type 2 diabetes mellitus (T2DM), insulin resistance, abdominal obesity, hypertension, and hyperlipidemia. Until now, specific drugs such as metformin (MET) have been used to address its individual components; however, according to the recommendation of WHO, various plant extracts might be used as alternative medicines due to the side effects of pharmacologic agents. Policaptil Gel Retard^® (PGR), a macromolecule complex based on polysaccharides which slows down the absorption rates of carbohydrates and fats, proved effective against glucose abnormalities. Our study aimed to verify the short-term efficacy and safety of PGR under real-life conditions. Methods: We evaluated both the 6-month changes in metabolic parameters in Italian patients with MS and T2DM, and the 10-year CV risk score (10-y-CV-RS) from the CUORE equation, competitively randomized to Policaptil Gel Retard (2172 mg before each main meal); Group A, n = 75, or Metformin (1500–2000 mg/day equally divided between the two main meals), and Group B, n = 75. Results: Fasting plasma glucose and HbA1c decreased significantly and similarly (p < 0.001) in the two groups. A significant decrease in BMI (−20% in the PGR group (p < 0.01), −14.3% in the MET group (p < 0.05)), % visceral fat, and UA levels was also apparent in both groups (p < 0.01). The opposite occurred for lipid profile, which improved significantly in the PGR group but remained unchanged in the MET group. Consequently, only the PGR group experienced a significant decrease in the 10-y-CV-RS (31.4 ± 8.0 vs. 19.7 ± 5.2, p < 0.0001), whereas this remained unchanged in the MET group (32.2 ± 3.3 vs. 30.5 ± 8.7; p n.s.). Conclusions: PGR could represent a suitable alternative to MET as a first-line treatment option, especially now that an ever-increasing number of people prefer natural products based on plant extracts. This is particularly pertinent given that, besides trying to avoid gastrointestinal side-effects as much as possible, patients might be sensitive to ecotoxicology-related problems involving plants and animals caused by the worldwide spread of environmental MET metabolites.

Technological advances in the management and treatment of type 1 diabetes have afforded some patients the resources to better manage their condition and live full, healthy lives. One of these technologies is continuous glucose monitoring which allows patients and medical practitioners alike to receive real-time blood glucose readings, evaluate trends, and tailor insulin dosing to avoid both hyper- and hypoglycemic events. The benefit of such technology during exercise, particularly running or cycling, is invaluable. In this case report, we describe the effect of using a continuous glucose monitoring technology in a 38-year-old, brittle, type 1 diabetic female runner over two years. The combined effect of continuous glucose monitoring and exercise, primarily running, resulted in an almost two-fold reduction in HbA1C, a 21% reduction in total daily insulin usage from diagnosis approximately 20 years ago. The patient recorded an over 100% improvement in running capacity. Full article

Metabolic syndrome (MetS) is a major societal concern due to its increasing prevalence and its high risk of cardiovascular complications. The ketogenic diet (KD), a high fat, low carbohydrate, and non-caloric restrictive diet, is a new popular weight loss intervention but its beneficial effects are controversial. This study aims to gather all of the relevant studies using KD for metabolic disease treatment to determine its beneficial effects and evaluate its safety and efficacy for patients. Following the recommendations of the Preferred Reporting Items for Systematic Reviews and Meta-Analyses, we included 20 articles in the final review. Overall, most of the studies showed a significant effect of KD on weight loss (17/19 articles), BMI (7/7), glucose levels (9/13), insulin levels (7/9), HOMA-IR (4/5), HbA1c (7/7), total cholesterol (6/9), TG (13/15), AST (3/4), and ALT (3/5), and no major side effects. The results heterogeneity seems to be explained by a difference of diet composition and duration. In conclusion, KD is a safety diet which seems to be a promising approach for obesity and MetS treatment, even if the optimal carbohydrate proportion and diet duration must be explored to enhance the beneficial effects of KD.

Diabetes mellitus has become a non-infectious pandemic. The incidence of T2D has risen dramatically and recent rates have increased in many countries including Muslim countries. As the number of people who participate in Ramadan increases, health care professionals will need to become familiar with the traditions and help people stay healthy during the holy month of Ramadan. A key part of Ramadan is the practice of one month of fasting from sunrise to sunset. While this is a religious practice, it has significant impacts on the management of people with diabetes. This article will discuss the traditions associated with Ramadan and how to help people safely manage their diabetes while participating in Ramadan. Full article

Objective: Assess in a sample of people with type 1 diabetes mellitus whether mood and stress influence blood glucose levels and variability. Material and Methods: Continuous glucose monitoring was performed on 10 patients with type 1 diabetes mellitus, where interstitial glucose values were recorded every 15 min. A daily survey was conducted through Google Forms, collecting information on mood and stress. The day was divided into six slots of 4-h each, asking the patient to assess each slot in relation to mood (sad, normal or happy) and stress (calm, normal or nervous). Different measures of glycemic control (arithmetic mean and percentage of time below/above the target range) and variability (standard deviation, percentage coefficient of variation, mean amplitude of glycemic excursions and mean of daily differences) were calculated to relate the mood and stress perceived by patients with blood glucose levels and glycemic variability. A hypothesis test was carried out to quantitatively compare the data groups of the different measures using the Student’s t-test. Results: Statistically significant differences (p-value < 0.05) were found between different levels of stress. In general, average glucose and variability decrease when the patient is calm. There are statistically significant differences (p-value < 0.05) between different levels of mood. Variability increases when the mood changes from sad to happy. However, the patient’s average glucose decreases as the mood improves. Conclusions: Variations in mood and stress significantly influence blood glucose levels, and glycemic variability in the patients analyzed with type 1 diabetes mellitus. Therefore, they are factors to consider for improving glycemic control. The mean of daily differences does not seem to be a good indicator for variability. Full article

Background: The aim of this study was to evaluate whether secreted frizzled-related protein 4 (sFRP4), secreted frizzled-related protein 5 (sFRP5), and chemerin serum concentrations in early pregnancy are associated with the development of gestational diabetes mellitus (GDM) in an obese cohort. In previous studies, increased sFRP4 and chemerin, and decreased sFRP5 concentrations were associated with the development of GDM in normal and overweight women. Methods: In this exploratory case control study, sFRP4, sFRP5, and chemerin serum concentrations were determined by ELISA in 50 obese women who developed GDM and 100 uncomplicated control pregnancies. Serum samples were obtained between 15⁺⁰–18⁺⁶ weeks’ gestational age and based on a priori known associations with the development of GDM, body mass index (BMI) and maternal age were selected for adjustment in multivariate analyses. Results: In this obese cohort (median BMI 35.7 kg/m², IQR 33.2–40.3 kg/m²), the biochemical markers showed no association with GDM: sFRP5 odds ratio (OR) 0.44 (95% confidence interval (CI) 0.01–23.18, p = 0.687), sFRP4 OR 0.55 (95% CI 0.09–3.52, p = 0.528), and chemerin OR 3.47 (95% CI 0.05–227.72, p = 0.560). Adjustment for BMI and maternal age did not influence the association. None of the markers were significantly correlated with insulin resistance (HOMA2-IR). Conclusion: No association was found between sFRP4, sFRP5, or chemerin concentration and the development of GDM in a cohort of obese pregnant women. The absence of the association may indicate that these proteins play a lesser biological role in the pathophysiology of GDM in obese women. Full article

Background: Diabetes is a complex disease requiring a multidisciplinary approach. However, the dynamics of this collaboration and the involvement of healthcare providers remain unclear. Aim(s): To explore the composition, the division of roles/tasks, and the collaboration in a diabetes team. Methods: A qualitative, explorative study with six focus groups was conducted, of which four focus groups were with healthcare providers (n = 34) and two with informal caregivers and persons with diabetes (n = 13). In addition, two in-depth interviews with doctors were performed. An iterative process of data analysis took place, guided by the Qualitative Analysis Guide of Leuven (QUAGOL). Results: All participants confirm the importance of patient empowerment and the fact that the person with diabetes should have a central role within the team. However, this has not been achieved yet. This research gives a clear insight into the dynamics of a diabetes team. Roles and tasks are allocated according to the specific expertise and knowledge of the different healthcare providers. Interprofessional collaboration is the ultimate goal. However, the diabetes team is often formed ad hoc depending on the needs of the person with diabetes and the preferences for collaboration of the healthcare providers. Furthermore, this study revealed some important bottlenecks with regard to the knowledge of healthcare providers, persons with diabetes and their informal caregivers, the regulation and reimbursement. Discussion: Our study uncovers the dynamics of a diabetes team and its members. Healthcare providers work mainly alone, except in hospitals, where they can consult other healthcare providers briefly if necessary. Although collaboration proves to be difficult, all healthcare providers ask for a more intensive interprofessional collaboration. Conclusion: In order to improve quality of diabetes care, patient-centered care and the satisfaction of patients, informal caregivers, and healthcare providers, efforts have to be made to facilitate interprofessional collaboration. This can be achieved by sharing information via electronic shared patient records, coordination, overview, local task agreements, simplified legal regulations, and an adjusted financing system.

The global burden of diabetes and cardiovascular disease (CVD) is increasing and, while cardiovascular event incidence is falling in some high-income countries (HICs), increasing rates are being observed in many middle-income countries (MICs) and low-income countries (LICs). There have been discrepancies in the availability and affordability of medicines for diabetes and cardiovascular disease among countries, of which LICs and MICs have seen low availability and affordability. The Prospective Urban Rural Epidemiological (PURE) study is a large prospective cohort study of over 200,000 people aged 35–70 years from 27 HICs, MICs, and LICs across six geographical regions (Asia, Africa, Europe, South America, North America, and the Middle East). Analyses from this study have contributed greatly to the understanding of the determinants of cardio–metabolic health in LICs and MICs especially. Here, we discuss information learned from the PURE study regarding the availability and affordability of key medicines for diabetes and cardiovascular disease. Full article

Recent Mucorales-mediated outbreaks of infections and an association of fungal infection with COVID-19 cases, as observed for COVID-19-associated mucormycosis (CAM), have posed new challenges for the management of patients in critical care units. Diabetes and hyperglycemia are integrally linked to the severity of COVID-19, and uncontrolled diabetes mellitus and COVID-19 have recently been (independently or in combination) associated with the emergence of aggressive mucormycosis due to attendant defects in innate immune recognition pathways. Therefore, the identification of novel global cellular stressors upregulated during diabetes to understand the contribution of diabetes-associated metabolic vulnerabilities can help build a Metabolic-Stress-Associated Interactome (MSAI). This interactome can help reshape the metabolic inflammation (meta-inflammation) underlying the clinical manifestations of COVID-19 to facilitate the rational design of effective therapies for COVID-19 and CAM. Accordingly, an important area of research in COVID-19 therapeutics is engaged with identifying diabetes-associated pan-cellular stressors to understand their role in immune deregulation during COVID-19 and CAM, including investigating the distant trans-neuro-vascular–endocrine axis’s role in coordinating cellular-stress recognition, transmission, compensation, and decompensation during inter-organ regulation of metabolic homeostasis in diabetes. We reviewed clinico-pathological and laboratory data to propose potential diabetes-linked novel neo-vulnerabilities that can reshape the olfactory mucosal immune landscape during airway infections such as COVID-19 and CAM.

Growing evidence suggests that healthcare provider advice may reduce alcohol use, increase physical activity, and improve the adoption of other desirable lifestyle behaviors among patients. However, how brief interventions and other provider–patient interactions can shape the cumulative adoption of multiple modifiable behaviors is less well studied for diabetes prevention and control. Using weighted Internet panel survey data from a large socio-demographically diverse urban population in the United States (n = 1003), the present study describes differences in group characteristics among those who ‘had been ever diagnosed’ with prediabetes/diabetes versus those who had not. It also examines the associations between the cumulative adoption of lifestyle behaviors and each of the following: (a) lifetime prediabetes/diabetes diagnosis; (b) brief lifestyle intervention exposure (i.e., ever received provider encouragement to modify lifestyle behaviors); and (c) recent provider–patient communication about diabetes. There were several group differences among those who ‘had been ever diagnosed’ with prediabetes/diabetes versus those who had not, by age, employment status, health status, nutrition knowledge, blood pressure/hypertension diagnosis, and diabetes-related health behaviors (p < 0.05). Each of the three provider–patient interactions of interest were positively associated with a higher cumulative sum of adopted modifiable lifestyle behaviors for diabetes prevention and management. The results suggest that provider advice/provider–patient interactions of any type can have a salutary impact on whether individuals with prediabetes or type 2 diabetes will engage in recommended lifestyle behavior modifications.

Diabetes mellitus is one of the most frequently occurring metabolic disorders (DMs), impairing healthy life around the globe, with mild-to-severe secondary complications. DM is associated with secondary complications, including diabetic retinopathy (DR), which damages the retina and can lead to vision loss. Diabetic patients often suffer from extreme retinal capillary aneurysms, hemorrhage, and edema, which is likely to lead to non-proliferative or proliferative diabetic retinopathy (NPDR or PDR) and diabetic macular edema (DME). Several epidemiological studies have illustrated that the occurrence of DR can vary by age of diabetes onset, diabetes type, and ethnicity. Although DR is very well-known, the complexity of its etiology and diagnosis makes therapeutic intervention difficult and challenging. We have reviewed different pathological aspects of diabetic retinopathy and its underlying mechanism of occurrence. In this review, we aim to provide an in-depth understanding and illustration of the progression of diabetic retinopathy, its pathophysiology, epidemiology, and prospective therapeutic targets.

Before the discovery of insulin and the critical role of the pancreas vis-à-vis diabetes mellitus pathophysiology, childhood diabetes or what we now call type 1 or autoimmune diabetes mellitus was almost universally fatal. In limited-resource countries (LRC) around the world, this remains sadly true because of the expense and unavailability of medical care, medical information, and/or medications. In 1889, Minkowski and Mering identified the pancreas as the likely source of the problem in pancreatectomized dog experiments, and Langerhans, working with Virchow, identified the islands of pancreatic tissue now named after Langerhans as the likely source of the problem. Prior to that, Cawley, Boucherdat, Zuelzer, Gley, de Meyer, Schafer, Scott, Kleiner, and Paulescu all worked on this problem with varying results until Banting, Best, MacLeod, and Collip in Toronto in 1921 successfully treated pancreatectomized dogs with an alcohol-based pancreatic extract and then were the first to do the same with children and adults with diabetes, starting with Leonard Thompson in early 1922. Urinary and blood glucose levels were reduced, and clinical symptoms decreased concurrently. The magnificent medical historical work by Professor Michael Bliss, also from Toronto, as well as an excellent US NPR Television documentary, describes the trials and tribulations of this event that culminated in the “fastest Nobel Prize” awarded. Progressive biopharmaceutical advances have modified insulin from pigs and cows and then genetically engineered insulin to work much faster and also much slower to provide more modernized ways of providing insulin. Insulin pens then replaced vial and syringe administration, and then insulin pumps coupled with continuous blood glucose sensors have made delivery more physiologic in addition to more attention paid to nutrition advice, education, and psychosocial support around the world. Programs to assist delivery of expensive insulin to LRC administered by Insulin for Life, Life for a Child (LFAC), Changing Diabetes in Children (CDIC) coupled with support by ISPAD (International Society for Pediatric and Adolescent Diabetes) have continued to make such advances available thorough wonderful philanthropy in insulin manufacturers and manufacturers of blood glucose monitoring equipment and insulin pump/sensor suppliers.

Background: There has been evidence that metabolic syndrome (MetS) may increase the risk of frailty. However, there is limited evidence on this association in Asian populations. Aims: This study aims to identify the association between MetS and frailty in older people in Vietnam. Methods: This is a cross-sectional analysis of a dataset that was obtained from an observational study on frailty and sarcopenia in patients aged ≥60 at a geriatric hospital in Vietnam. Frailty was defined by the frailty phenotype. The participants were defined as having MetS if they had ≥3 out of 5 criteria from the definition of the National Cholesterol Education Program (NCEP) Adults Treatment Panel (ATP) III. Multiple logistic regression models were performed to estimate the risk of having frailty in patients with MetS. Results: Of the 669 participants (mean age 71, 60.2% female), 62.3% had MetS and 39.0% were frail. The prevalence of frailty was 42.2% in participants with MetS and 33.7% in participants without MetS (p = 0.029). On the logistic regression models, MetS was associated with an increased likelihood of being frail (adjusted OR 1.52, 95%CI 1.01–2.28), allowing for age, sex, education, nutritional status, history of hospitalization, and chronic diseases. Conclusion: There was a significant association between MetS and frailty in this population. Further longitudinal studies are required to confirm this association. Full article

Diabetes is a common and complex disease affecting multiple organ systems throughout the body. With a consensus in care guidelines emphasizing the importance of glycemic control in determining the disease progression, people with diabetes worldwide have been placed on medication regimens targeting glucose stability from a variety of pathophysiologic pathways. Each of these medications also possesses its own potential for adverse events. In recent years, there has been increased reports of skin reactions to diabetes medications, adding to the more widely known eruptions such as insulin-induced lipohypertrophy and contact dermatitis of subcutaneous injections. The authors searched PubMed, Google, and Embase for articles including adverse reactions to anti-hyperglycemic medications. Key words and titles searched included, “antidiabetic drugs”, “skin reactions”, “adverse drug reactions”, “allergic reactions”, “diabetes”, “metformin”, “insulin”, “DPP4 inhibitors”, “thiazolindineones”, “sulfonylureas”, “SGLT2 inhibitors”, “GLP-1 agonists”, “diabetic medication”, “injection site reactions”. As a result, a total of 59 papers are included in this review. The great majority were case reports ranging from benign fixed drug eruptions to severe cutaneous reactions that threaten patients’ lives. Increasing physician awareness of both the potential for, and presentation of, such reactions to diabetes medications can reduce hospitalizations and optimize care in an already vulnerable patient population.

Type 1 diabetes (T1D) is an autoimmune disease characterized by the destruction of insulin-producing pancreatic β-cells by their own immune system, resulting in lifelong insulin deficiency. Continuous exogenous insulin replacement therapy is the current standard of care for T1D. Transplantation of primary pancreatic islets or the entire pancreas is a viable remedy for managing patients with autoimmune T1D. However, this strategy is not feasible due to several obstacles, including a scarcity of donors, islet cells, and poor vascular engraftment of islets post-transplantation, as well as the need for prolonged immune suppression. Innovative approaches must be developed to counteract pancreatic β-cell destruction and salvage endogenic insulin production, thereby regulating blood glucose levels. This review includes an overview of autoimmune T1D, immune cells involved in T1D pathophysiology, and immunotherapy-based strategies to treat and prevent autoimmune T1D. Recent immunotherapy progress toward targeting pancreatic islet-specific immune pathways tangled tolerance has fueled the advancement of therapies that may allow for the prevention or reversal of this autoimmune T1D while avoiding other adverse reactions associated with the previous attempt, which was mostly immunosuppressive. As a result, significant efforts are currently underway to improve the efficacy of immunotherapy-based approaches by leveraging the beneficial actions of immune cells, specifically effector CD4⁺, CD8⁺, and regulatory T cells. This review will provide an overview of currently available immune-based therapeutic options for T1D and will examine the growing evidence that supports the use of immune cell-based approaches to improve therapeutic outcomes in the prevention or reversal of autoimmune T1D.
