Cardiovascular Complications of Diabetes: From Microvascular to Macrovascular Pathways

Vascular actions of Ang 1-7 and Ang 1-8 through EDRFs and EDHFs in non-diabetes and diabetes mellitus

The renin-angiotensin system (RAS) plays a pivotal role in regulating vascular homeostasis, while angiotensin 1-8 (Ang 1-8) traditionally dominates as a vasoconstrictor factor. However, the discovery of angiotensin 1-7 (Ang 1-7) and Ang 1-8 has revealed counter-regulatory mechanisms mediated through endothelial-derived relaxing factors (EDRFs) and endothelial-derived hyperpolarizing factors (EDHFs). This review delves into the vascular actions of Ang 1-7 and Ang 1-8 in both non-diabetes mellitus (non-DM) and diabetes mellitus (DM) conditions, highlighting their effects on vascular endothelial cell (VECs) function as well. In a non-DM vasculature context, Ang 1-8 demonstrate dual effect including vasoconstriction and vasodilation, respectively. Additionally, Ang 1-7 induces vasodilation upon nitric oxide (NO) production as a prominent EDRFs in distinct mechanisms. Further research elucidating the precise mechanisms underlying the vascular actions of Ang 1-7 and Ang 1-8 in DM will facilitate the development of tailored therapeutic interventions aimed at preserving vascular health and preventing cardiovascular complications.

The role of estimated glucose disposal rate in predicting cardiovascular risk among general and diabetes mellitus population: a systematic review and meta-analysis

BACKGROUND

Estimated glucose disposal rate (eGDR) is a measure of insulin sensitivity. While recent evidence suggests its role in cardiovascular risk assessment in Type 1 diabetes, its associations with cardiovascular disease (CVD), diabetic microvascular complications (DMC), and mortality across different populations remain unclear.

METHODS

We systematically searched Medline, EMBASE, Web of Science, and the Cochrane Library up to September 1st, 2024, following PRISMA guidelines. We examined associations between eGDR and CVD, DMC (including diabetic retinopathy, nephropathy, and peripheral neuropathy), and all-cause mortality using random-effects models. Secondary analysis assessed mean eGDR levels in diabetes populations.

RESULTS

Nineteen observational studies (185,810 participants) examined clinical outcomes, while 50 studies reported mean eGDR values. In patients with Type 1 diabetes (T1DM), each 1-unit (mg/kg/min) increase in eGDR was associated with lower risks of CVD (HR 0.78; 95% CI 0.69-0.87; I2 = 68%) and all-cause mortality (HR 0.83; 95% CI 0.79-0.88; I2 = 0%). The association between eGDR and DMC in T1DM was not statistically significant (HR 0.86; 95% CI 0.72-1.03; I2 = 25%). In patients with Type 2 diabetes (T2DM), each 1-unit (mg/kg/min) increase in eGDR was associated with reduced all-cause mortality (HR 0.90; 95% CI 0.84-0.97; I2 = 62%). Similarly, in the general population, each 1-unit (mg/kg/min) increase in eGDR was associated with decreased mortality risk (HR 0.88; 95% CI 0.82-0.94; I2 = 48%). The pooled mean eGDR was higher in patients with T1DM (8.19 mg/kg/min; 95% CI 7.81-8.57; I2 = 99%) compared to those with T2DM (7.03 mg/kg/min; 95% CI 4.89-9.17; I2 = 100%).

CONCLUSIONS

Higher eGDR levels were consistently associated with lower risks of CVD and mortality in T1DM, with similar associations observed for mortality in T2DM. In the general population, higher eGDR levels were associated with reduced mortality risk. The relationship between eGDR and DMC requires further investigation, particularly in T2DM. These findings suggest eGDR's potential utility as a risk assessment tool, though its clinical application may vary across different populations.

Diabetes Mellitus and Associated Vascular Disease: Pathogenesis, Complications, and Evolving Treatments

Diabetes mellitus is a metabolic disorder, characterized by elevated blood sugar levels (hyperglycemia) and insulin dysregulation. This disease is associated with morbidity and mortality, including significant potential vascular complications. High levels of hyperglycemia lead to not only elevated levels of reactive oxygen species but also advanced glycation end products, which are detrimental to the vascular endothelium and reduce protective compounds such as nitric oxide and prostacyclin. This damage contributes to the development of both macrovascular and microvascular complications. The present investigation explores the pathophysiological mechanisms of diabetic vascular complications and evaluates current management strategies, including lifestyle modifications, pharmacological treatments, and emerging therapies. The review underscores the importance of ongoing progress in diabetes management and patient education to lead to optimal patient-health outcomes and quality of life for individuals with diabetes mellitus.

Oxidative stress and pediatric diabetic cardiovascular complications: emerging research and clinical applications

The prevalence and incidence of diabetes in pediatrics have dramatically increased over the last three decades. Comparatively, pediatric diabetes has faster pancreatic β-cells decline and early progression to complications compared with adult diabetes. Therefore, diabetic complications are a major concern in children and adolescents with diabetes. Diabetes has detrimental effects on the macro- and microvascular systems, resulting in cardiovascular diseases, leading causes of morbidity and mortality in youth with diabetes. Oxidative stress plays a critical role in developing cardiovascular complications in the context of pediatric diabetes. In pediatric patients with diabetes, several factors can contribute to the development of excess reactive oxygen species and oxidative stress, including nutritional deficiencies, puberty, environmental exposures, and metabolic disorders such as obesity and high blood pressure. The present study aims to raise awareness of diabetic cardiovascular complications in children and adolescents with diabetes and the role of oxidative stress and their molecular mechanisms in the pathogenesis of cardiovascular complications. In addition, some novel therapeutic strategies for the treatment and prevention of diabetic cardiovascular complications in the pediatric populations are highlighted. In summary, children and adolescents with diabetes no matter type 1 diabetes (T1D) or type 1 diabetes (T2D), have many features similar to those in adults with same kinds of diabetes, but also have many their own features distinct from adults. By developing targeted therapies and preventive measures, healthcare providers can better address the rising incidence of diabetes-related complications in children and adolescents.

Fecal Microbiome and Urine Metabolome Profiling of Type 2 Diabetes

Type 2 diabetes is a prevalent metabolic disorder with serious health consequences, necessitating both enhanced diagnostic methodologies and comprehensive elucidation of its pathophysiological mechanisms. We compared fecal microbiome and urine metabolome profiles in type 2 diabetes patients versus healthy controls to evaluate their respective diagnostic potential. Using a cohort of 94 subjects (48 diabetics, 46 controls), this study employed 16S rRNA amplicon sequencing for fecal microbiome analysis and GC-MS for urinary metabolomics. While fecal microbiome alpha diversity showed no significant differences between groups, urinary metabolomics demonstrated distinct structural patterns and higher evenness in type 2 diabetes patients. The study identified several diabetes-associated urinary metabolites, including elevated levels of glucose and inositol, along with decreased levels of 6 urine metabolites including glycolic acid, hippurate, and 2-aminoethanol. In the fecal microbiome, genera such as Escherichia-Shigella showed positive correlation with type 2 diabetes, while Lacticaseibacillus demonstrated negative correlation. Receiver operating characteristic curve analyses revealed that urinary metabolites exhibited superior diagnostic potential compared to fecal microbiome features, with an area under the curve of 0.90 for the combined metabolite model versus 0.82 for the integrated bacterial taxa model. These findings suggest that urinary metabolomics may offer a more reliable approach for type 2 diabetes diagnosis compared to fecal 16S metabarcoding, while highlighting the potential of multi-marker panels for enhanced diagnostic accuracy.

Exploring Endothelial Cell Dysfunction's Impact on the Brain-Retina Microenvironment Connection: Molecular Mechanisms and Implications

The intricate linking between the health of blood vessels and the functioning of neurons has attracted growing attention in the context of disorders that affect the neurological environment. Endothelial cells, forming the blood-brain barrier and blood-retinal barrier, play a fundamental role in maintaining the integrity of the brain-retina microenvironment connection. This review explores the molecular foundations of endothelial cell dysfunction and its implications for the brain-retina interaction. A comprehensive analysis of the complex factors contributing to endothelial dysfunction is presented, including oxidative stress, inflammation, reduced nitric oxide signaling, and disrupted vascular autoregulation. The significance of endothelial dysfunction extends to neurovascular coupling, synaptic plasticity, and trophic support. To our knowledge, there is currently no existing literature review addressing endothelial microvascular dysfunction and its interplay with the brain-retina microenvironment. The review also explains bidirectional communication between the brain and retina, highlighting how compromised endothelial function can disrupt this vital crosstalk and inhibit normal physiological processes. As neurodegenerative diseases frequently exhibit vascular involvement, a deeper comprehension of the interaction between endothelial cells and neural tissue holds promise for innovative therapeutic strategies. By targeting endothelial dysfunction, we may enhance our ability to preserve the intricate dynamics of the brain-retina microenvironment connection and ameliorate the progression of neurological disorders.

Collaboration among stakeholders is essential for improving global well-being.

Free radicals and their impact on health and antioxidant defenses: a review

Free radicals, characterized by the presence of unpaired electrons, are highly reactive species that play a significant role in human health. These molecules can be generated through various endogenous processes, such as mitochondrial respiration and immune cell activation, as well as exogenous sources, including radiation, pollution, and smoking. While free radicals are essential for certain physiological processes, such as cell signaling and immune defense, their overproduction can disrupt the delicate balance between oxidants and antioxidants, leading to oxidative stress. Oxidative stress results in the damage of critical biomolecules like DNA, proteins, and lipids, contributing to the pathogenesis of various diseases. Chronic conditions such as cancer, cardiovascular diseases, neurodegenerative disorders, and inflammatory diseases have been strongly associated with the harmful effects of free radicals. This review provides a comprehensive overview of the characteristics and types of free radicals, their mechanisms of formation, and biological impacts. Additionally, we explore natural compounds and extracts studied for their antioxidant properties, offering potential therapeutic avenues for managing free radical-induced damage. Future research directions are also discussed to advance our understanding and treatment of free radical-associated diseases.

Natural Compounds in Kidney Disease: Therapeutic Potential and Drug Development

Diabetic kidney disease (DKD) poses a major global health challenge, affecting millions of individuals and contributing to substantial morbidity and mortality. Traditional treatments have focused primarily on managing symptoms and slowing disease progression rather than reversing or halting kidney damage. However, recent advancements in natural compound research have unveiled promising new avenues for therapeutic development. Extensive research has been conducted to showcase the antioxidant advantages for kidney health, supporting the potential effectiveness of natural and synthetic products in clinical and experimental research. Bioactive substances found in large quantities in food, such as polyphenols, have emerged as adjuvants. This review manuscript aims to provide a comprehensive overview of natural compounds and their potential efficacy, mechanisms of action, and clinical applications in the prevention and treatment of various kidney diseases. This review emphasizes the connection between oxidative stress and inflammation in diabetic nephropathy (DN), which leads to harmful effects on kidney cells due to pathological damage. A lower incidence of DM2-related problems and a slower progression of end-stage renal disease have been associated with the consumption of these compounds.

Aerobic Exercise and Metformin: A Dual Approach to Enhancing Glycemic Maintenance in Type 2 Diabetes Mellitus

Type 2 diabetes mellitus (T2DM) is a widespread metabolic condition characterized by elevated glucose levels followed by deficiency in insulin secretion. Metformin notably decreased the incidence of T2DM by 31% and it exerts its effects through various signaling pathways. Databases searched included PubMed, Google Scholar, and Scopus from 2000 to 2024. One of the primary mechanisms involves AMPK activation which causes reduced lipogenesis and improved fatty acid oxidation in the liver and muscles. Key molecules affected by metformin include acetyl-CoA carboxylase (ACC) and sterol regulatory element-binding protein 1c (SREBP-1c), both involved in lipid synthesis regulation. Aerobic exercise has also emerged as a crucial component in managing T2DM due to its improved effects on hyperglycemia and insulin sensitivity. Key signaling pathways affected in T2DM include the PI3K/Akt, AMP-activated protein kinase (AMPK), and MAPK/ERK pathways which play essential roles in regulating glucose homeostasis, glycogenesis, and insulin secretion. When comparing the mechanisms and efficacy of aerobic exercise and metformin, it becomes evident that aerobic exercise primarily enhances physical fitness and metabolic function, while metformin exerts its effects through biochemical pathways involving AMPK activation. Aerobic exercise and metformin are effective for managing T2DM, though they operate through different mechanisms. Regular aerobic exercise improves insulin sensitivity, enhances cardiovascular health, and promotes weight loss, while metformin primarily decreases hepatic gluconeogenesis and enhances insulin secretion. Understanding the intricate signaling pathways affected by metformin and aerobic exercise provides valuable insights into its mechanisms of action and clinical implications for treating diabetic patients effectively.

Melatonin attenuates responses to angiotensin II in isolated aortic rings of STZ-induced type 1-like DM rats

BACKGROUND

In patients with diabetes mellitus (DM), vascular endothelial dysfunction (VED) is the main reason for impaired life expectancy. Melatonin (MEL) demonstrates wide-ranging effects across various organs and exhibits pleiotropic characteristics. The current study aims to investigate the modulatory roles of MEL vascular response to angiotensin II (Ang II) and its receptors including angiotensin type 1 receptor (AT-1 R) and angiotensin type 2 receptor (AT-2 R) in isolated thoracic aorta of non-diabetes (non-DM) and diabetes (DM) rats.

METHODS

The thoracic aortae were isolated in order to investigate the influence of MEL on AT-1 R, using valsartan (VAL) and MT-2Rusing luzindole (LUZ) via dose-response curve (DRC) measurement of Ang II reactivity. In addition, AT-1 R was involved in this study, under PD123319 with ADInstrument organ bath (Panlab apparatus, Harvard University, USA).

RESULTS

The maximum response of Ang II was increased significantly in DM condition. In addition, AT-1 R was completely blocked under VAL, while AT-2 R was upregulated in the DM group. The combination of VAL and PD123319 led to abolishing the Ang II effect dramatically as well. Melatonin alone reduced Ang II in the DM group dramatically. This effect was also observed with MEL, PD1213319, and VAL combination, as well as, with MEL, LUZ, and PD1213319 combination.

CONCLUSIONS

Melatonin has been demonstrated to modulate both AT-1 R and AT-2 R and has influenced the reactivity of Ang II in the aortas of diabetic rats through highly complex mechanisms.

Microfluidic chip systems for characterizing glucose-responsive insulin-secreting cells equipped with FailSafe kill-switch

BACKGROUND

Pluripotent cell-derived islet replacement therapy offers promise for treating Type 1 diabetes (T1D), but concerns about uncontrolled cell proliferation and tumorigenicity present significant safety challenges. To address the safety concern, this study aims to establish a proof-of-concept for a glucose-responsive, insulin-secreting cell line integrated with a built-in FailSafe kill-switch.

METHOD

We generated β cell-induced progenitor-like cells (βiPLCs) from primary mouse pancreatic β cells through interrupted reprogramming. Then, we transcriptionally linked our FailSafe (FS) kill-switch, HSV-thymidine kinase (TK), to Cdk1 gene using a CRISPR/Cas9 knock-in strategy, resulting in a FailSafe βiPLC line, designated as FSβiPLCs. Subsequently we evaluated and confirmed the functionality of the drug-inducible kill-switch in FSβiPLCs at different ganciclovir (GCV) concentrations using our PDMS-based transcapillary microfluidic system. Finally, we assessed the functionality of FSβiPLCs by characterizing the dynamics of insulin secretion in response to changes in glucose concentration using our microfluidic perfusion glucose-stimulated insulin secretion (GSIS) assay-on- chip.

RESULTS

The βiPLCs exhibited Ins1, Pdx1 and Nkx6.1 expression, and glucose responsive insulin secretion, the essential properties of pancreatic beta cells. The βiPLCs were amenable to genome editing which allowed for the insertion of the kill-switch into the 3'UTR of Cdk1, confirmed by PCR genotyping. Our transcapillary microfluidic system confirmed the functionality of the drug-inducible kill-switch in FSβiPLCs, showing an effective cell ablation of dividing cells from a heterogeneous cell population at different ganciclovir (GCV) concentrations. The Ki67 expression assessment further confirmed that slow- or non-dividing cells in the FSβiPLC population were resistant to GCV. Our perfusion glucose-stimulated insulin secretion (GSIS) assay-on-chip revealed that the resistant non-dividing FSβiPLCs exhibited higher levels of insulin secretion and glucose responsiveness compared to their proliferating counterparts.

CONCLUSIONS

This study establishes a proof-of-concept for the integration of a FailSafe kill-switch system into a glucose-responsive, insulin-secreting cell line to address the safety concerns in stem cell-derived cell replacement treatment for T1D. The microfluidic systems provided valuable insights into the functionality and safety of these engineered cells, demonstrating the potential of the kill-switch to reduce the risk of tumorigenicity in pluripotent cell-derived insulin-secreting cells.

Diabetes and the associated complications: The role of antioxidants in diabetes therapy and care

Diabetes mellitus (DM) is a chronic metabolic disorder characterized by high blood sugar levels (hyperglycemia). Poorly managed diabetes can lead to complications affecting multiple organ systems. Antioxidants play a crucial role in reducing oxidative stress caused by reactive oxygen species (ROS), primarily triggered by uncontrolled high blood sugar levels in diabetes. Antioxidants like vitamin C, E, selenium, and alpha-lipoic acid, when used as supplements, have shown promise in reducing oxidative stress markers and improving antioxidant status in laboratory and animal studies and diabetic patients. Antioxidant supplementation may help reduce the risk of diabetic complications such as neuropathy, nephropathy, retinopathy, and cardiovascular disease. Additionally, antioxidants also have anti-inflammatory properties, which could be beneficial in reducing inflammation associated with diabetes. Antioxidant supplementation has been shown to enhance endothelial function, insulin sensitivity, and glucose metabolism, thereby aiding in glycemic control and overall diabetic management. Combining antioxidants with certain medications may have therapeutic benefits, such as effectively neutralizing free radicals and enhancing the regulation of antioxidant defense systems. This review presents an update on diabetes, the sources of free radical generation, the body's natural defense mechanisms, the clinical evidence regarding using antioxidants in managing diabetic complications, and the potential new therapeutic approaches. Overall, antioxidant supplementation may offer some benefits in managing diabetic complications. However, further studies are needed to understand the mechanisms of action, determine the optimal supplementation, explore potential interactions with other medications, and conduct long-term studies to establish the possible use of antioxidants for optimal benefits in diabetes care.

Diabetes Mellitus and Cardiovascular Disease: Exploring Epidemiology, Pathophysiology, and Treatment Strategies

Diabetes mellitus (DM) affects 537 million people as of 2021, and is projected to rise to 783 million by 2045. This positions DM as the ninth leading cause of death globally. Among DM patients, cardiovascular disease (CVD) is the primary cause of morbidity and mortality. Notably, the prevalence rates of CVD is alarmingly high among diabetic individuals, particularly in North America and the Caribbean (46.0%), and Southeast Asia (42.5%). The predominant form of CVD among diabetic patients is coronary artery disease (CAD), accounting for 29.4% of cases. The pathophysiology of DM is complex, involving insulin resistance, β-cell dysfunction, and associated cardiovascular complications including diabetic cardiomyopathy (DCM) and cardiovascular autonomic neuropathy (CAN). These conditions exacerbate CVD risks underscoring the importance of managing key risk factors including hypertension, dyslipidemia, obesity, and genetic predisposition. Understanding the genetic networks and molecular processes that link diabetes and cardiovascular disease can lead to new diagnostics and therapeutic interventions. Imeglimin, a novel mitochondrial bioenergetic enhancer, represents a promising medication for diabetes with the potential to address both insulin resistance and secretion difficulties. Effective diabetes management through oral hypoglycemic agents (OHAs) can protect the cardiovascular system. Additionally, certain antihypertensive medications can significantly reduce the risk of diabetes-related CVD. Additionally, lifestyle changes, including diet and exercise are vital in managing diabesity and reducing CVD risks. These interventions, along with emerging therapeutic agents and ongoing clinical trials, offer hope for improved patient outcomes and long-term DM remission. This study highlights the urgent need for management strategies to address the overlapping epidemics of DM and CVD. By elucidating the underlying mechanisms and risk factors, this study aims to guide future perspectives and enhance understanding of the pathogenesis of CVD complications in patients with DM, thereby guiding more effective treatment strategies.

The relationship of dietary omega-3 fatty acid and omega-6 to omega-3 ratio intake and likelihood of type 2 diabetes in a cross-sectional study

BACKGROUND

There is a belief that consuming a significant amount of omega-3 and omega-6 fatty acids can positively affect chronic diseases. However, the connection between these fatty acids and type 2 diabetes mellitus (T2DM) risk remains unclear. To explore this further, we conducted a study to investigate the relationship between dietary intake of omega-3 and omega-6 fatty acids (FA), as well as omega-6 to omega-3 ratio, and the odds of T2DM.

METHODS

Our research involved a cross-sectional analysis of data from the Ravansar Non-Communicable Disease (RaNCD) cohort. We evaluated their dietary habits using a comprehensive 118-item food frequency questionnaire (FFQ). To determine the aforementioned association, we employed logistic regression analysis to calculate odds ratios (OR) and 95% confidence intervals (CIs).

RESULTS

The prevalence of T2DM among 8744 qualified participants was 751 (8.6%). After considering all the possible factors that could affect the outcome, high dietary omega-3 intake was associated with a 58% lower likelihood of T2DM (OR: 0.42; 95% CI: 0.32, 0.56; P-trend: <0.001). In contrast, participants at the fourth quartile of the dietary omega 6 to omega 3 FA ratio had a higher odd of T2DM (OR: 1.42; 95%CI: 1.11, 1.84; P-trend: 0.01). Nevertheless, there was no significant connection between the highest and lowest quartile of dietary omega-6 intake (OR: 0.91; 95% CI: 0.71, 1.17; P-trend: 0.80).

CONCLUSION

According to the study, consuming omega-3 fatty acids through diet was linked with lower odds of type 2 diabetes. Conversely, an elevated omega-6 to omega-3 ratio was associated with a greater likelihood of T2DM.

Evaluating Risk Factors and the Burden of Silent Myocardial Ischemia Among Diabetic Patients

INTRODUCTION

Silent myocardial ischemia (SMI) is a significant concern for diabetic patients, often remaining undetected until severe complications arise. Prolonged hyperglycemia, poor glycemic control, and lifestyle factors contribute to its risk, with older adults and those with long-standing diabetes particularly vulnerable.

OBJECTIVE

To assess the prevalence and predictors of SMI in adults with diabetes, emphasizing long-term management and monitoring.

METHODOLOGY

A longitudinal observational study was conducted at Nishtar Medical University, Multan, from October 2020 to September 2022, involving 388 adults with diabetes for at least five years. Patients with significant cardiovascular diseases or recent medication-affecting biomarkers were excluded. Data collection included demographics, medical history, and clinical assessments such as HbA1c levels, 12-lead resting ECGs, and treadmill exercise stress tests, with myocardial perfusion imaging (MPI) for those unable to perform stress tests. Statistical analyses using IBM SPSS (version 22) incorporated univariate and multivariate logistic regression to identify predictors of SMI, adjusting for confounders such as age, sex, smoking, and blood pressure. Thresholds included microalbuminuria at 30-300 mg/24 hours and HbA1c ≥7%, with missing data addressed through multiple imputations.

RESULTS

Among the participants, the prevalence of SMI was 48%, increasing to 58% in those with microalbuminuria. Significant predictors included the duration of diabetes (OR 1.28, 95% CI: 1.08-1.52, p=0.001), HbA1c levels (OR 1.75, 95% CI: 1.42-2.16, p<0.001), age (OR 1.05, 95% CI: 1.01-1.09, p=0.035), and smoking status (OR 1.42, 95% CI: 1.05-1.92, p=0.025). Smoking status was based on self-report. Notably, microalbuminuria showed a strong association with SMI (OR 2.89, 95% CI: 2.10-3.98, p<0.001). The distribution of participants was balanced in terms of age and gender, with a mean age of 58 years (SD 9.4), and 52% were male. No unexpected findings were observed, and the results aligned with the anticipated relationships between the variables.

CONCLUSION

This study highlights a concerning prevalence of SMI among diabetic patients, emphasizing the importance of monitoring diabetes duration and glycemic control, particularly in individuals with microalbuminuria. Regular follow-up care, including routine ECGs, stress tests, and biomarker assessments, is crucial for improving cardiovascular outcomes in this high-risk population. Limitations such as the observational design and potential self-report bias in smoking status may affect the generalizability of the findings. Future research should focus on large-scale, multicenter studies to validate these findings and explore interventions that could reduce the burden of SMI in diabetic patients.

Synthesis of Carborane-Thiazole Conjugates as Tyrosinase and 11β-Hydroxysteroid Dehydrogenase Inhibitors: Antiproliferative Activity and Molecular Docking Studies

The presented study depicts the synthesis of 11 carborane-thiazole conjugates with anticancer activity, as well as an evaluation of their biological activity as inhibitors of two enzymes: tyrosinase and 11β-hydroxysteroid dehydrogenase type 1 (11β-HSD1). The overexpression of tyrosinase results in the intracellular accumulation of melanin and can be observed in melanoma. The overexpression of 11β-HSD1 results in an elevation of glucocorticoid levels and has been associated with the aggravation of metabolic disorders such as type II diabetes mellitus and obesity. Recently, as the comorbidity of melanomas and metabolic disorders is being recognized as an important issue, the search for new therapeutic options has intensified. This study demonstrates that carborane-thiazole derivatives inhibit both enzymes, exerting beneficial effects. The antiproliferative action of all newly synthesized compounds was evaluated using three cancer cell lines, namely A172 (human brain glioblastoma), B16F10 (murine melanoma) and MDA-MB-231 (human breast adenocarcinoma), as well as a healthy control cell line of HUVEC (human umbilical vein endothelial cells). The results show that 9 out of 11 newly synthesized compounds demonstrated similar antiproliferative action against the B16F10 cell line to the reference drug, and three of these compounds surpassed it. To the best of our knowledge, this study is the first to demonstrate dual inhibitory action of carborane-thiazole derivatives against both tyrosinase and 11β-HSD1. Therefore, it represents the first step towards the simultaneous treatment of melanoma and comorbid diseases such as type II diabetes mellitus.

Advancing drug discovery: Thiadiazole derivatives as multifaceted agents in medicinal chemistry and pharmacology

In this dispensation of rapid scientific and technological advancements, significant efforts are being made to curb health-related diseases. Research discoveries have highlighted the value of heterocyclic compounds, particularly thiadiazole derivatives, due to their diverse pharmacological activities. These compounds play a crucial role in therapeutic medicine and the development of effective drugs. Thiadiazoles are five-membered heterocyclic compounds consisting of one sulfur and two nitrogen atoms. This review explores advanced synthesis techniques, including the use of heterogeneous catalysts, microwave-assisted methods, ultrasound-assisted synthesis, solvent-free processes, multicomponent reactions, copper-catalyzed aerobic oxidative annulation, intramolecular cyclization, click-chemistry supported synthesis, and alkali-promoted, transition-metal-free mediated synthesis. These methods enhance the diversity and potential applications of thiadiazole compounds. Furthermore, this study provides up-to-date information on the key pharmacological activities of thiadiazole derivatives, highlighting their potential in therapeutic medicine for drug development. The structure-activity relationship (SAR) is also discussed to better understand their interactions and safety in biological systems. This work aims to expand on the reported chemistry and pharmacological potential of the thiadiazole moiety to validate their efficacy as promising pharmacophores in drug design and development.

Exploring the translational impact of type 1 diabetes on cerebral neurovascular function through ECoG-LSCI

Type 1 diabetes mellitus (T1DM) can result in complications such as retinopathy, nephropathy, and peripheral neuropathy, which can lead to brain dysfunction. In this study, we investigated the effects of T1DM on cerebral neurovascular function in mice. Streptozotocin (STZ) is known to induce T1DM in animals; thus, we used an STZ-induced diabetes model to evaluate the effects of hyperglycemia on brain morphology and neurovascular tissue. Neurovascular coupling is the connection between neuronal activity and cerebral blood flow that maintains brain function. The ECoG-LSCI technique combines electrocorticography (ECoG) and laser speckle contrast imaging (LSCI) to detect cortical spreading depression (CSD) as a marker of neurovascular coupling and measure corresponding neurovascular function. Our results suggested that in the STZ group, hyperglycemia affected excitatory neurotransmission and metabolism, leading to reductions in intercellular signaling, somatosensory evoked potential (SSEP) amplitudes, and CSD transmission rates. Western blot data further revealed that brain-derived neurotrophic factor (BDNF) and neuronal nuclear antigen levels were reduced in the STZ group. Abnormalities in glucose metabolism in the brain and increased phosphorylation of AKT and GSK3 are hypothesized to be responsible for these decreases. Overall, this study highlights the importance of glucose metabolism in normal brain physiology and demonstrates that hyperglycemia disrupts neurovascular coupling and affects cerebral neurovascular function and that the degree of CSD is positively correlated with the extent of brain tissue damage. Further research is essential to gain a complete understanding of the related mechanisms and the implications of these findings.

Design, Synthesis of 3-(Aryl)-1-(2-p-tolylthiazol-4-yl)prop-2-en-1-ones as Alpha(α)-Amylase Inhibitors

α-Amylase inhibition is vital in controlling diabetic complications. Herein, we have synthesized a hybrid scaffold based on thiazole-chalcone to access α-amylase inhbition. The proposed structures were verified with spectroscopic techniques (UV-Vis., FT-IR, 1H-, 13C-NMR, and elemental analysis). The synthesized compounds were evaluated for their α-amylase and antioxidant potential. In vitro hemolytic assay was performed to test biocompatibility of all compounds. Among tested compounds, 4 c (IC50=3.8 μM), 4 g (IC50=14.5 μM), and 4 f (IC50=17.1 μM) were found excellent α-amylase inhibitors. However, none of the tested compounds exhibited significant antioxidant activity. All compounds showed less lysis than Triton X-100, but compounds 4 f and 4 h had the least lysis at all tested concentrations and were found to be safe for human erythrocytes. Molecular docking study was performed to evaluate the binding interactions of ligands with human pancreatic α-amylase (HPA). The binding score -8.09 to -8.507 kcal/mol revealed strong binding interactions in the ligand-protein complex. The docking results supplemented the observed α-amylase inhibition and hence augment the scaffold to serve as leads for the antidiabetic drug development.

Therapeutic potential of Tithonia diversifolia extract: Modulating IL-35, TNF-α, and hematology profile in streptozotocin-induced rat model

BACKGROUND

Diabetes mellitus is a significant global health issue with increasing prevalence worldwide.

AIM

This study aims to investigate the potential of Tithonia diversifolia extract (TE) in lowering interleukin-35 (IL-35), tumor necrosis factor-alpha (TNF-α), and hematological profile in streptozotocin (STZ)-induced rats.

METHODS

A total of 24 rats were divided into four treatment groups: control (P0), diabetic induction (P1), diabetic induction + TE (P2), and diabetic induction + quercetin (P3). Diabetes mellitus was induced by a single-dose injection of stz (60 mg/kg). TE treatment was administered orally for 7 days. On the 8th day post-treatment, all animals were euthanized, and blood samples were collected to assess inflammatory parameters, including IL-35, TNF-α, GPx, and hematological profiles. Kidney organs were fixed in 10% buffered neutral formalin for histopathological analysis. Data were analyzed using ANOVA followed by Duncan's test (p < 0.05).

RESULTS

Evaluation of the hematological profile revealed significant improvements in the P2 and P3 groups, with decreased leukocytes, hemoglobin, lymphocytes, and neutrophils, as well as significantly lower IL-35 and TNF-α levels observed in diabetic rats following TE treatment.

CONCLUSION

TE treatment exhibited promising effects in reducing inflammatory markers and restoring hematological parameters in diabetic rats, indicating its potential as a therapeutic agent in diabetic rats.

Strategies for Cardiovascular Disease Prevention in Type 1 Diabetes: A Comprehensive Review

Cardiovascular disease (CVD) is a leading cause of morbidity and mortality among individuals with type 1 diabetes (T1D), necessitating effective prevention strategies. This comprehensive review consolidates current knowledge and evidence on preventing CVD in T1D patients.

Knowledge, Attitude, Practice, and Barriers Regarding Prediabetes Among Adults in Saudi Arabia

Background Prediabetes refers to a clinical condition in which blood glucose levels are elevated but do not meet the threshold for diabetes. Prediabetes is now thought to be reversible; lifestyle changes and other interventions can be successfully implemented during the prediabetes phase to avoid the development of type 2 diabetes. This study aims to improve health outcomes among Saudi community members who are at risk of developing prediabetes by assessing their knowledge, attitudes, practices, and barriers using a validated prediabetes questionnaire. Methods This study employed a cross-sectional design across various regions of Saudi Arabia. It included patients who were all non-diabetic Saudi adults over 18 years old and visited outpatient clinics. Structured questionnaires, which included participants' demographic information, knowledge, attitudes, practices, and barriers related to prediabetes, were employed. The collected data were analyzed using Statistical Product and Service Solutions (SPSS; IBM SPSS Statistics for Windows, Armonk, NY) software program. Results Data from 641 patients were collected in this survey. The respondents were predominantly female (330, 51.5%), with the mean ± SD of age being 36.3 ± 12.3. The participant knowledge levels of prediabetes were found to be good (399, 62.2%), moderate (193, 30.1%), and poor (49, 7.6%). The knowledge scores were significantly associated with age (P = 0.027), educational level (P < 0.001), education in the medical field (P = 0.019), and monthly family income (P = 0.009). The overall attitude of the participants toward prediabetes was generally positive (468, 73%). The practices related to diet and lifestyle among the participants were generally poor (538, 84%). Some participants did not take blood sugar tests because they were not available (121, 18.9%), lacked time (179, 27.9%), and were afraid of learning the test results (130, 20.3%). Conclusion The study found that, despite possessing an adequate level of knowledge and positive attitudes, Saudi patients poorly practice prevention methods for prediabetes. It highlights the need for targeted interventions to improve prediabetes awareness, promote healthier lifestyles, and address screening barriers. Prioritizing evidence-based strategies that cater to diverse demographic needs can prevent the progression of type 2 diabetes and enhance public health. The findings emphasize the importance of health education in Saudi Arabia and suggest that future research should focus on overcoming barriers, such as management complexity, diagnosis apprehension, and time constraints for check-ups.

Objective

This study aimed to evaluate the efficacy and safety of polyethylene glycol loxenatide (PEG-Loxe) compared to those of dapagliflozin in patients with mild-to-moderate diabetic kidney disease (DKD), a prevalent microvascular complication of type 2 diabetes mellitus (T2DM). The study is set against the backdrop of increasing global diabetes incidence and the need for effective DKD management.

Methods

This study constituted a single-center, randomized, open-label, clinical trial. The trial included patients with mild-to-moderate DKD and suboptimal glycemic control. Eligible participants were randomly allocated to one of the two groups for treatment with either PEG-Loxe or dapagliflozin. The primary endpoint was the change in UACR from baseline at 24 weeks.

Results

Overall, 106 patients were randomized and 80 patients completed the study. Following 24 weeks of treatment, the PEG-Loxe group exhibited a mean percent change in baseline UACR of -29.3% (95% confidence interval [CI]: -34.8, -23.7), compared to that of -31.8% in the dapagliflozin group (95% CI: -34.8, -23.7). Both PEG-Loxe and dapagliflozin showed similar efficacy in reducing UACR, with no significant difference between the groups (p = 0.336). The HbA1c levels decreased by -1.30% (95% CI: -1.43, -1.18) in the PEG-Loxe group and by -1.29% (95% CI: -1.42, -1.17) in the dapagliflozin group (p = 0.905). The TG levels decreased by -0.56 mmol/L (95% CI: -0.71, -0.42) in the PEG-Loxe group and -0.33 mmol/L (95% CI: -0.48, -0.19) in the dapagliflozin group (p = 0.023). Differences in TC, HDL-C, LDL-C, SBP, and DBP levels between the groups were not statistically significant (all p > 0.05). Safety profiles were consistent with previous findings, with gastrointestinal adverse events being more common in the PEG-Loxe group.

Conclusions

PEG-Loxe is as effective as dapagliflozin in improving urine protein levels in patients with mild-to-moderate DKD and offers superior benefits in improving lipid profiles. These findings support the use of PEG-Loxe in DKD management, contributing to evidence-based treatment options.

The Effect of Glucagon-Like Peptide-1 (GLP-1) Receptor Agonists on the Lipid Profile of Diabetic Patients Using Statins: A Retrospective Cohort Study in the Diabetic Center of King Salman Bin Abdulaziz Hospital, Saudi Arabia

Background Dyslipidemia is a common complication of type 2 diabetes mellitus (T2DM), which is the leading cause of morbidity and mortality in developed countries, including Saudi Arabia. Injectable glucagon-like peptide-1 receptor agonists (GLP-1RA) are recent therapies found to be effective in treating dyslipidemia in diabetic patients by acting similarly to the body's internal glucagon peptide hormone, regulating blood sugar levels and reducing triglycerides and low-density lipoprotein (LDL) levels. Aim of the study This retrospective cohort study aimed to investigate the effect of GLP-1RA on the lipid profile of dyslipidemia diabetic patients who were not controlled using statins. Methods Data were collected from the medical records of male and female diabetic patients with dyslipidemia (uncontrolled by statins) who were administered to the diabetic center of King Salman Bin Abdulaziz Hospital in Riyadh, Saudi Arabia, and received GLP-1RA (dulaglutide) from June 2023 to August 2023. The primary endpoint was the change in triglycerides and LDL-C levels after three months of using dulaglutide, and the secondary endpoints included the change in body weight, BMI, and HbA1c%. Descriptive analysis was conducted to present numerical and categorical data. The Wilcoxon signed-rank test was used to compare numerical data before and after using dulaglutide. Ethical considerations were taken into account by ensuring anonymous data collection and obtaining IRB approval before data collection. Results The study included 102 patients with a median (interquartile range (IQR)) age of 59 (14) years. Females constituted 55.2% of the population. Obesity (96.1%), hypertension (71.6%), and retinopathy (13.7%) were the most commonly reported comorbidities. The study showed a significant reduction in body weight, BMI, HbA1c, hemoglobin, mean corpuscular volume (MCV), serum LDL-C, and triglyceride concentrations after three months of using dulaglutide (p<0.001). Conclusion Our study results confirm the positive effect of the GLP-1RA (dulaglutide) on the lipid profile of diabetic patients with dyslipidemia uncontrolled by statins.

Sympathetic Overactivity and Parasympathetic Impairment in Type 2 Diabetes: An Analysis of Cardiovascular Autonomic Functions

Background Cardiovascular autonomic dysregulation is a known complication of Type 2 diabetes mellitus (T2DM), characterized by dysregulation in heart rate (HR) and blood pressure (BP). These disruptions in cardiovascular autonomic control can significantly influence the morbidity and mortality associated with the disease. Objectives This study aims to investigate how T2DM affects cardiovascular autonomic functions by comparing responses in HR, BP, and specific autonomic function tests between a control group without diabetes and a study group with diabetes. The research questions focus on assessing HR variability, baroreflex sensitivity, and other autonomic parameters to determine the extent of cardiovascular autonomic dysregulation in diabetic patients.  Methods This cross-sectional study involved 200 adults, divided equally between a control group (n = 100) and a T2DM study group (n = 100). The exclusion criteria included cardiovascular diseases and renal impairment. Data collection involved assessing baseline characteristics such as age and BMI. Cardiovascular measures, including HR, systolic blood pressure (SBP), and diastolic blood pressure (DBP), were recorded after a five-minute rest. Autonomic function tests assessed sympathetic and parasympathetic responses, including the cold pressor test and the isometric hand grip exercise test. The statistical analysis was conducted using IBM SPSS Statistics for Windows, Version 25 (Released 2017; IBM Corp., Armonk, New York, United States), focusing on independent t-tests to compare between groups, considering p-values <0.05 as significant. Potential confounding variables like age and BMI were accounted for in the analysis to ensure robust findings  Results The study group showed a higher average BMI (28.95 ± 5.60) compared to the control group (26.50 ± 5.70) and an increased resting HR (74.20 ± 8.60 bpm vs. 69.30 ± 9.10 bpm). The SBP was slightly higher in the study group (115.00 ± 19.00 mmHg vs. 114.50 ± 8.90 mmHg), while the DBP was lower (71.50 ± 10.70 mmHg vs. 72.80 ± 6.70 mmHg). The autonomic function tests showed a smaller increase in SBP (106.80 ± 11.00 mmHg) and a larger increase in DBP (75.90 ± 8.30 mmHg) upon standing in the study group compared to controls. The cold pressor test indicated increased sympathetic activity in the study group, with significant rises in SBP (133.70 ± 10.30 mmHg) and DBP (83.40 ± 9.00 mmHg) compared to the control group (SBP: 114.31 ± 11.87 mmHg, DBP: 71.85 ± 8.67 mmHg). These findings demonstrate marked differences in cardiovascular autonomic responses between the groups. Conclusions This study demonstrates that T2DM significantly impacts cardiovascular autonomic functions, with diabetic patients showing altered HR and BP indicative of increased sympathetic and decreased parasympathetic activity. These autonomic dysfunctions may heighten cardiovascular risk in diabetic individuals. Our findings highlight the importance of monitoring and managing cardiovascular autonomic functions in diabetic patients to reduce their risk of cardiovascular complications. Further research should investigate the underlying mechanisms and the effectiveness of interventions to improve autonomic function in this population.

Metabolic Dysregulation and Its Multifaceted Impact on Cardiovascular Autonomic Control in Type 2 Diabetes Mellitus: Insights From Comprehensive Assessment

BACKGROUND

Type 2 diabetes mellitus (T2DM) is associated with a spectrum of metabolic dysfunctions that significantly elevate the risk of cardiovascular disorders. Understanding the intricate relationship between metabolic control and cardiovascular autonomic function in individuals with T2DM is crucial for effective management and the prevention of associated complications. This insight is foundational in developing targeted strategies that can mitigate the heightened cardiovascular risks inherent to this condition, thereby enhancing patient outcomes and quality of life.

AIM

The primary aim of the study was to explore the interconnections between various aspects of metabolic control in individuals with T2DM. This includes examining how glycemic variability, lipid profiles, body mass index (BMI), duration of diabetes, inflammatory markers, and cardiovascular autonomic function are interrelated.

METHODS

A cross-sectional study was conducted involving 100 individuals with T2DM and 100 control participants. HbA1C levels, glycemic variability, lipid profile, BMI, duration of diabetes, and inflammatory markers were assessed. Cardiovascular autonomic function parameters, including resting heart rate and blood pressure responses, were evaluated using standardized tests.

RESULTS

People with T2DM had significantly higher levels of glycosylated hemoglobin (HbA1C) compared to controls (mean difference = 2.95%, p < 0.001). Elevated HbA1C levels were correlated with increased resting heart rate (mean difference = 10 bpm, p < 0.001) and aberrant blood pressure responses during autonomic function assessments (p < 0.01 for systolic blood pressure; p < 0.05 for diastolic blood pressure). Glycemic variability (correlation coefficient (𝑟) = 0.75, p < 0.001) and dyslipidemia (elevated triglycerides and LDL cholesterol, reduced HDL cholesterol) were associated with cardiovascular autonomic dysfunction. Higher BMI values in T2DM individuals were independently correlated with alterations in autonomic function (𝑟 = 0.60, p < 0.001). The prolonged duration of diabetes was linked to greater impairment in autonomic function (mean decrease = 0.5 points per year, p < 0.01). In the T2DM group, higher levels of inflammatory markers (C-reactive protein and interleukin-6) were seen, which may have led to problems with the autonomic nervous system.

CONCLUSION

Metabolic dysregulation, such as high HbA1C levels, glycemic variability, dyslipidemia, obesity, having diabetes for a long time, and inflammation, is linked to cardiovascular autonomic dysfunction in T2DM. Early intervention targeting these metabolic abnormalities may mitigate the risk of cardiovascular complications in individuals with T2DM.

Effect of Angiotensin 1-7 Peptide Agonist AVE 0991 on Diabetic Endothelial Dysfunction in an Experimental Animal Model: A Possible Tool to Treat Diabetic Erectile Dysfunction

Background The renin-angiotensin system and its metabolites are crucial in the pathogenesis and progression of complications of diabetes. Aim In this study, we aimed to evaluate the effect of angiotensin 1-7 non-peptide agonist AVE 0991 (576 ug/kg/day i.p.) on diabetic endothelial dysfunction. Materials and methods In this experimental animal study, we investigated the effects of angiotensin 1-7 non-peptide agonist AVE 0991 (576 ug/kg/day i.p.) treatment in male Wistar rats. Diabetes was created via injecting streptozotocin (55 mg/kg/i.p., single dose). Following the cavernous tissue submaximal phenylephrine contraction, relaxation responses were obtained by applying electrical field stimulation (0.5 ms, 40 V) for 15 seconds at 2, 4, 8, 16, 32, and 64 Hz, with two-minute intervals, respectively. To evaluate the effect of nitric oxide, the responses were compared by incubating with 100 mM N(gamma)-nitro-L-arginine methyl ester (L-NAME) for 20 minutes. Additionally, Y-27632 and sodium nitroprusside responses were evaluated in tissues contracted with submaximal doses of phenylephrine. Results Following a submaximal contraction of phenylephrine in the aorta rings, relaxation responses obtained with acetylcholine, sodium nitroprusside, and Y-27632 were impaired in diabetic rats; however, significant results were obtained with treatment. Although there was no significance between the groups in the electrical field stimulation responses, there was a significant dose-dependent difference in the treatment group in this parameter after L-NAME, sodium nitroprusside, and Y-27632 relaxation. Conclusions We determined that treatment with a non-peptide receptor antagonist of angiotensin 1-7, an enzyme detected in the aortic and cavernosum endothelium, may be a promising alternative for treating the complications of diabetes.
