During the COVID-19 pandemic, fewer in-person clinic visits resulted in fewer point-of-care (POC) HbA1c measurements. In this sub-study, we assessed the performance of alternative glycemic measures that can be obtained remotely, such as HbA1c home kits and Glucose Management Indicator (GMI) values from Dexcom Clarity. Home kit HbA1c (n = 99), GMI, (n = 88), and POC HbA1c (n = 32) were collected from youth with T1D (age 9.7 ± 4.6 years). Bland–Altman analyses and Lin’s concordance correlation coefficient (𝜌_c) were used to characterize the agreement between paired HbA1c measures. Both the HbA1c home kit and GMI showed a slight positive bias (mean difference 0.18% and 0.34%, respectively) and strong concordance with POC HbA1c (𝜌_c = 0.982 [0.965, 0.991] and 0.823 [0.686, 0.904], respectively). GMI showed a slight positive bias (mean difference 0.28%) and fair concordance (𝜌_c = 0.750 [0.658, 0.820]) to the HbA1c home kit. In conclusion, the strong concordance of GMI and home kits to POC A1c measures suggest their utility in telehealth visits assessments. Although these are not candidates for replacement, these measures can facilitate telehealth visits, particularly in the context of other POC HbA1c measurements from an individual. Full article

Background: COVID-19 has been associated with a higher risk of death in patients with diabetes mellitus (DM). However, there is a dearth of data regarding the effects of diabetic ketoacidosis (DKA) in these patients. We explored the in-hospital outcomes of patients who presented with COVID-19 and DKA. Methods: A propensity score-matched observational retrospective cohort study was conducted in hospitalized patients with COVID-19 in the public healthcare system of New York City from 1 March 2020 to 31 October 2020. Patients were matched, and a subgroup analysis of patients with DKA and COVID-19 and patients without COVID-19 was conducted. Results: 13,333 (16.0%) patients with COVID-19 and 70,005 (84.0%) without COVID-19 were included in the analysis. The in-hospital mortality rate was seven-fold in patients with DKA and COVID-19 compared to patients with COVID-19 and without DKA (80 (36.5%) vs. 11 (5.4%), p < 0.001). Patients with COVID-19 and DKA had a two-fold higher likelihood for in-hospital death (OR: 1.95; 95% CI: 1.41–2.70; p < 0.001) after adjusting for multiple variables. Conclusions: DKA was associated with significantly higher in-hospital mortality in hospitalized patients with COVID-19. Full article

We demonstrate that the recovery of cervical vertebral arterial blood flow access to the rhomboid fossa causes the restoration of HbA1c level for the patients with pre-diabetic (pre-DM) condition. This observation is in good agreement with the consideration of the human body as a dissipative structure. Such consideration is the focus of the recently announced centralized aerobic-anaerobic energy balance compensation (CAAEBC) theory. According to the theory, observed connections between high blood pressure (HBP) and the lifted level of HbA1c can be hypothetically linked through the restrictions of blood flow access to rhomboid fossa, causing the delivery of incorrect information of blood oxygen availability. Below we provide detailed information of how in this case CAAEBC theory explains the very initiation of multiple chronic diseases, starting with type 2 Diabetes Mellitus (DM). Full article

Type 2 diabetes mellitus is a widespread and a chronic disease associated with micro- and macrovascular complications and is a well-established risk factor for cardiovascular disease, which are among the most important causes of death in diabetic patients. This disease is strongly affected by sex and gender: sex-gender differences have been reported to affect diabetes epidemiology and risk factors, as well as cardiovascular complications associated with diabetes. This suggests the need for different therapeutic approaches for the management of diabetes-associated complications in men and women. In this review, we describe the known sex-gender differences in diabetic men and women and discuss the therapeutic approaches for their management. The data reported in this review show that a sex-gender approach in medicine is mandatory to maximize the scientific rigor and value of the research. Sex-gender studies need interdisciplinarity and intersectionality aimed at offering the most appropriate care to each person. Full article

Obstructive sleep apnoea (OSA) and type 2 DM mellitus (T2DM) share obesity as a major risk factor. Furthermore, these conditions share overlapping mechanisms including inflammation, activation of the autonomic nervous system, and hypoxia-linked endocrinopathy. Hence, the pathogenesis of the two conditions may be more closely related than previously recognised. This raises the question of whether treatment of OSA might assist resolution of obesity and/or T2DM. Here, we present a narrative review of the literature to identify clinical and scientific data on the relationship between obstructive sleep apnoea and T2DM control. We found there is a paucity of adequately powered well-controlled clinical trials to directly test for a causal association. While routine screening of all T2DM patients with polysomnography cannot currently be justified, given the high prevalence of sleep disordered breathing in the overweight/obese population, all T2DM patients should at a minimum have a clinical assessment of potential obstructive sleep apnoea risk as part of their routine clinical care. In particular, screening questionnaires can be used to identify T2DM subjects at higher risk of OSA for consideration of formal polysomnography studies. Due to morbid obesity being a common feature in both T2DM and OSA, polysomnography should be considered as a screening tool in such high-risk individuals. Full article

Insulin signaling plays a key role in glucose uptake, glycogen synthesis, and protein and lipid synthesis. In insulin-resistant states like obesity and type 2 diabetes mellitus, these processes are dysregulated. Regular physical exercise is a potential therapeutic strategy against insulin resistance, as an acute bout of exercise increases glucose disposal during the activity and for hours into recovery. Chronic exercise increases the activation of proteins involved in insulin signaling and increases glucose transport, even in insulin resistant states. Here, we will focus on the effect of acute exercise on insulin signaling and protein kinase B (Akt) pathways. Activation of proximal proteins involved in insulin signaling (insulin receptor, insulin receptor substrate-1 (IRS-1), phosphoinoside-3 kinase (PI3K)) are unchanged in response to acute exercise/contraction, while activation of Akt and of its substrates, TBC1 domain family 1 (TBC1D1), and TBC domain family 4 (TBC1D4) increases in response to such exercise/contraction. A wide array of Akt substrates is also regulated by exercise. Additionally, AMP-activated protein kinase (AMPK) seems to be a main mediator of the benefits of exercise on skeletal muscle. Questions persist on how mTORC1 and AMPK, two opposing regulators, are both upregulated after an acute bout of exercise. Full article

Objective: The main aim of this study was to implement the Chronic Care Model (CCM) for the self-management of type 2 diabetes in primary health care settings of rural areas of Pakistan and identify its effectiveness and develop strategies for overcoming its challenges. The two core elements of the Chronic Care Model: patient Self-Management Support (SMS) and Delivery System Design (DSD), were implemented to improve the quality of life and risk behaviour of type 2 diabetes patients in the middle-aged population of rural Pakistan. Methods: Thirty patients with type 2 diabetes and 20 healthcare professionals were included in this study consisting of 10 general practitioners and 10 nurses recruited from various clinics (medical centres) of Al-Rehman Hospital in Abbottabad, Pakistan. The quantitative content analysis method was used to identify the frequency of the most recurring statements. A t-test was performed to see the mean difference of HbA1c at baseline after 3-months and 6-months follow-up between male and female patients with diabetes. The hypothesis was tested to identify that diabetes self-management has a gendered dimension in rural areas of Pakistan. Results: The quantitative analysis demonstrated that diabetes self-management has a gendered dimension in the rural areas of Pakistan as the mean difference of HbA1c after a 6-month intervention of the two components of the chronic care model between male and female patients of diabetes was 0.83 (p = 0.039) with 95% CI (−0.05; −1.61). The mean difference in BMI after the intervention of 6 months between males and females was significant (p < 0.05). The mean difference was 4.97 kg/m², p = 0.040 with 95% CI (−0.24; −9.69). The results have shown that the two components of CCM were effective and improved clinical outcomes for diabetes patients of the rural areas of Pakistan. Conclusions: The application of the two Chronic Care Model’s components provided a viable structure for diabetes self-management education and assistance. As a result, developing systems that incorporate long-term diabetes self-management education has an effect on the health care system’s outcomes. Full article

Autoimmune pancreatic β-cell loss and destruction play a key role in the pathogenesis and development of type 1 diabetes, with a prospective increased risk for developing micro- and macrovascular complications. In this regard, orally administrated verapamil, a calcium channel antagonist, usually intended for use as an anti-arrhythmic drug, has previously shown potential beneficial effects on β-cell preservation in new-onset type 1 diabetes. Furthermore, observational data suggest a reduced risk of type 2 diabetes development. The underlying pathophysiological mechanisms are not well investigated and remain widely inconclusive. The aim of this narrative review was to detail the role of verapamil in promoting endogenous β-cell function, potentially eligible for early treatment in type 1 diabetes, and to summarize existing evidence on its effect on glycemia in individuals with type 2 diabetes.

Several factors affect the relationship between a diabetic patient and a healthcare worker. Among these, there is the well-being of healthcare workers and how they perceive their work environment, especially in the context of the presence or absence of gender inequality. To show the importance of these aspects, a selected sample of healthcare workers who were exposed daily to people (mainly diabetic patients) within the working environment were interviewed. The different opinions of the interviewees show that in an environment where factors that negatively affected their work and personal well-being were minimized, healthcare workers were able to fully express their potential. They expressed great satisfaction with their work involving daily contact with patients, while achieving the type of patient–healthcare worker relationship model desired for a better management of diabetic patients’ care.
