Type 2 diabetes (T2D) has increased worldwide at an alarming rate. Metabolic syndrome (MetS) is a major risk factor for T2D development. One of the main reasons for the abrupt rise in MetS incidence, besides a sedentary lifestyle, is the westernized diet consumption, with high content of industrialized foods, rich in added dietary sugars (DS), mainly sucrose and fructose. It has been suggested that a higher intake of DS could impair metabolic function, inducing MetS, and predisposing to T2D. However, it remains poorly explored how excessive DS intake modulates mitochondrial function, a key player in metabolism. This review explores the relationship between increased consumption of DS and mitochondrial dysfunction associated with T2D development, pointing to a contribution of the diet-induced accumulation of advanced glycation end-products (AGEs), with brief insights on the impact of maternal high-sugar diet and AGEs consumption during gestation on offspring increased risk of developing T2D later in life, contributing to perpetuate T2D propagation.

Diabetes mellitus is a metabolic disorder that is prima facie a cause for numerous macro and micro vascular complications. A common macroscopic complication associated with diabetes is cardiomyopathy. Cardiomyopathy refers to diseases of the heart muscle, where the heart muscle becomes enlarged, thick, or rigid. As cardiomyopathy worsens, the heart becomes weaker and is unable to conduct the right amount of blood through the body and maintain a normal electrical rhythm. This can lead to heart failure or arrhythmias. Chronic diabetes is one of the instigating factors behind the etiology of this cardiac complication. Type-II diabetes is associated with impaired glucose metabolism that increases the dependence of a diabetic heart on fatty acid oxidation to meet its functional demands, resulting in mitochondrial uncoupling, glucotoxicity, lipotoxicity and initially subclinical cardiac dysfunction that finally gives way to heart failure. The increasing diabetic population with cardiac disorders and the ironically decreasing trend in newer medications to counter this complication leave us at a crossroads for pharmacological management of diabetic cardiomyopathy. Keeping this in view, the present study proclaims a newly developed polyherbal combination (PHC) with three herbs, namely Tinospora cordifolia, Withania somnifera and Boerhavia diffusa based in olive oil and administered in fixed dose (PHC-6 and PHC-10) to screen its cardioprotective potential against a well-established experimental model for diabetic cardiomyopathy. The three herbs mentioned have been known through the traditional literature for their antidiabetic and cardioprotective roles, hence they became the obvious choice. The study follows an experimental model proposed by Reed et al., where the capacity of the β-cell is unobtrusively impeded without totally compromising insulin release, bringing about a moderate disability in glucose resilience. Various sophisticated parameters, namely intraventricular septum thickness of hearts, Western blot of α/β- MHC monoclonal antibody (Ab), cardiac pyruvate dehydrogenase (PDH) activity, medium chain acyl coenzyme A dehydrogenase (MCAD) enzyme, etc. showed promising results where treatment with PHC (PHC-6 and PHC-10) significantly (*** p < 0.001 and **** p < 0.0001) prevented the symptoms of cardiomyopathy in subsequent groups when compared to disease control group.
糖尿病是一种代谢性疾病，是引起许多大血管和微血管并发症的首要原因。与糖尿病相关的常见的宏观并发症是心肌病。心肌病指的是心肌疾病，即心肌变大、变厚或变硬。随着心肌病的恶化，心脏变得虚弱，无法将适量的血液输送到全身，也无法维持正常的电节律。这会导致心力衰竭或心律失常。慢性糖尿病是这种心脏并发症病因背后的诱发因素之一。ii型糖尿病与糖代谢受损相关，这增加了糖尿病心脏对脂肪酸氧化的依赖，以满足其功能需求，导致线粒体解偶联、糖毒性、脂肪毒性和最初的亚临床心功能障碍，最终导致心力衰竭。糖尿病心肌病患者人数的增加和对抗这种并发症的新药物的具有讽刺意味的减少趋势使我们处于糖尿病心肌病药理学管理的十字路口。考虑到这一点，本研究宣布了一种新开发的多药组合(PHC)，包括三种草药，即Tinospora cordifolia, Withania somnifera和Boerhavia diffusa，以橄榄油为基础，以固定剂量(PHC-6和PHC-10)施用，以筛选其对糖尿病心肌病的心脏保护潜力。上述三种草药在传统文献中都有抗糖尿病和保护心脏的作用，因此它们成为了显而易见的选择。该研究遵循Reed等人提出的实验模型，其中β细胞的能力受到不明显的阻碍，而不会完全影响胰岛素的释放，从而导致葡萄糖恢复能力的中度残疾。各种复杂的参数，如心室间隔厚度，α/β- MHC单克隆抗体(Ab)的Western blot，心脏丙酮酸脱氢酶(PDH)活性，中链酰基辅酶A脱氢酶(MCAD)酶等均显示出令人满意的结果，与疾病对照组相比，PHC (PHC-6和PHC-10)治疗可显著预防心肌病症状(*** p < 0.001和**** p < 0.0001)。

Excessive sugar consumption is a risk factor for the development of several disorders, including metabolic, cardiovascular, neurological conditions and even some cancers, and has been linked to increased morbidity and mortality. The popularization of the typical Western diet, featured by an excessive intake of saturated fats and added sugars and a low consumption of unprocessed fruits, vegetables and fiber, may directly affect the composition and functionality of the gut microbiota, staggering the balance of the intestinal microbiome that ultimately culminates into gut dysbiosis. Although added sugars in the form of nutritive and non-nutritive sweeteners are generally considered as safe, a growing body of evidence correlate their consumption with adverse effects on gut microbial ecosystem; namely an abnormal synthesis of short-chain fatty acids, altered intestinal barrier integrity and chronic inflammation that often fuel a panoply of metabolic conditions. Accordingly, this work revisited the available preclinical evidence concerning the impact of different types of dietary sugars—nutritive and non-nutritive sweeteners—on gut microbiota and metabolic health. Future research should consider gender and species vulnerability when the impact of such substances on GM community and metabolic health is scrutinized in order to guide their adequate use at doses relevant to human use.

Impaired glucocorticoid signaling in diabetes mellitus and its relation to suppressed immune function and hyperglycemia during acute stroke has been shown to be detrimental. Therefore, the aim of this study was to examine the effect of glucocorticoid receptor (GCR) blockers in a type-2 diabetic mouse model following hypoxia–ischemia (HI). We induced stroke in diabetic db/db and non-diabetic db/+ mice by unilateral common carotid artery ligation followed by 20 min of HI. Mice were pretreated with RU-486, GCRII blocker (40 mg/kg), intraperitoneally, the day before, during stroke and post-HI. Blood and brain samples were collected at 24 h post-HI to measure blood glucose, corticosterone and infarct size. Similarly, another set of mice was pretreated with RU-486 + spironolactone, GCR1 blocker (25 mg/kg) subcutaneously for a week before inducing stroke and during recovery. Samples were collected at 48 h post-HI for various analyses. RU-486 treatment did not lower the blood glucose significantly, but RU-486 + spironolactone decreased the blood glucose in db/db mice post-HI. However, none of the treatment groups decreased the ischemia-induced serum corticosterone level or infarct size. This study suggests that even though GCR blockers improve hyperglycemia, they did not improve the infarct volume.

Non-alcoholic fatty liver disease (NAFLD) is associated with prediabetes and can be treated by using a combination of metformin and dietary modification. However, people often fail to adhere to dietary modifications and become more dependent on pharmaceutical intervention, and this affects the effectiveness of the drug. In this study, we investigated the effects of rhenium (V) compound with uracil-derived ligands on liver health in diet-induced prediabetic rats in both the presence and absence of dietary modification. Prediabetic male Sprague Dawley rats were treated with the rhenium (V) compound for 12 weeks in both the presence and absence of dietary modification while monitoring fasting blood glucose levels. Antioxidant enzyme activity, inflammation markers and liver enzymes were measured together with liver glycogen and plasma triglycerides after sacrificing. The administration of rhenium (V) compound to prediabetic rats in both the presence and absence of dietary modification resulted in reduced concentrations of fasting blood glucose and triglycerides. There was also reduced liver glycogen, oxidative stress and liver enzymes while increasing antioxidant enzymes. Altogether, the rhenium (V) compound ameliorated liver injury and prevented hepatotoxicity.

The research is based on a clinical observation of the neurological and neuro-cognitive status of 300 patients, belonging to the Partinico Hospital and the Post-Long Covid clinic, which had contracted the SARS-Cov2 virus in the period between April 2021 and May 2022. In this paper, we present the analysis of the first 100 patients subjected to a neurocognitive screening protocol. The procedure consists of tests that examine the mechanism of different brain domains to check for the presence of cognitive deficits that arose after the negativization of the viral infection. Through a neurocognitive protocol, the research aims to investigate different brain areas and mental functioning. This allowed us to raise the possibility that the presence of cognitive alterations may be related to the evidence of point-like brain alterations (from the cortex to the trunk) visible through neuroimaging techniques. In the article, we highlight the hypothesis that SARS-covid 2, as stated in recently published studies, can produce an alteration of executive functions such as to configure a real dysexecutive syndrome. This research evaluates the symptomatic gender variability within the sample, the presence of important differences in the affective state, and provides a first observation of the impact of SARS-Cov2 in diabetic pathology as well.

Approximately 40% of patients with type 2 diabetes (T2D) experience an early-morning rise in fasting glucose that is not effectively treated by available oral hypoglycemic agents. This study aimed to determine the acute effect of consuming almond butter as an evening snack on fasting and overnight interstitial glucose, compared to a no-snack control, in people with T2D. Adults with T2D, not taking insulin, were recruited to participate in this two-week randomized, controlled, crossover pilot study. Participants received 2 tbsp of natural almond butter as an evening snack, or a no-snack control, for one week each. Glucose was measured by continuous glucose monitor (CGM). Analyses were performed using linear mixed effect modeling in R. Ten adults (60% female; age: 57 ± 5.6 years) completed the study. The intervention did not significantly influence fasting glucose [4–6 a.m.; β = 5.5, 95% CI = [−0.9, 12.0], p = 0.091; Marginal R2 = 0.001, Conditional R2 = 0.954] or overnight glucose (12–3 a.m.; β = 5.5, 95% CI = [−0.8, 11.8], p = 0.089; Marginal R2 = 0.001, Conditional R2 = 0.958). Significant variability in continuously measured glucose was observed. These findings will inform the design of a larger investigation.

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.

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.","PeriodicalId":72798,"journal":{"name":"Diabetology","volume":"32 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2022-09-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"80888155","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

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 (ρc) 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 (ρc = 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 (ρc = 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.

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).
