This study presents a comprehensive analysis of 898 clinical trials conducted between 1999 and 2023, focusing on the interplay of metabolic syndrome, cardiovascular diseases (CVDs), and type 2 diabetes mellitus (T2D). This study draws upon data sourced from the International Clinical Trials Registry Platform (ICTRP) until August 2023. The trials were predominantly interventional (67%) or observational (33%). A geographical distribution reveals that while the United States registered approximately 18% of the trials, other regions like Australia, the United Kingdom, and multicounty trials made substantial contributions. Most studies (84%) included both male and female participants, with adults aged 18 to 65 years predominantly represented. The trials aimed at treatment (21%) and prevention (21%), emphasizing the dual focus on addressing existing CVD risk and preventing its development. Notably, CVDs (29%), T2D (8%), and the coexistence of both (21%) constituted the primary conditions of interest. Key interventions encompassed lifestyle and behavioral modifications, dietary supplementation, and drug therapies, with metformin and statins leading in pharmacological treatments. Interestingly, additional interventions such as glucagon-like peptide-1 agonists and dipeptidyl peptidase IV inhibitors are gaining recognition for their potential in managing metabolic syndrome-related conditions. Moreover, the report highlights a growing focus on inflammation, body mass index, blood pressure, body weight, and major adverse cardiovascular events as primary outcomes. Overall, the study highlights the importance of ICTRP as the source of data for clinical trials targeting metabolic syndrome, CVDs, and T2D and the growing recognition of diverse intervention strategies to address this critical global health concern.

Similar microorganisms, via similar mechanisms, play a role in the development of both pancreatic cancer (PC) and type 2 diabetes (T2D). Since the new onset of T2D is potentially one of the earliest signs of PC, it is highly plausible that a common denominator might be responsible for both, as the growth of the cancer will take a longer time to manifest compared to the insulin resistance. Although a variety of host-dependent factors and susceptibility play a role, and the mechanisms connecting the two diseases remain poorly understood, future well-designed trials should hypothesize whether a microbial intervention (modification and/or transplantation) results in a lower incidence and the better treatment of both diseases since the T2D–PC–gut microbiome interconnection seems scientifically logical.

Type 2 diabetes mellitus (T2DM) is a common metabolic disease characterised by insulin resistance and elevated blood glucose levels, affecting millions of people worldwide. T2DM individuals with dyslipidaemia have an increased risk of cardiovascular disease (CVD). A complex interplay of risk factors such as hyperglycaemia, dyslipidaemia, hypertension, obesity, inflammation, and oxidative stress favour the development of atherosclerosis, a central mechanism in the pathogenesis of cardiovascular disease. Dyslipidaemia, a hallmark of T2DM, is characterised by elevated triglycerides, decreased high-density lipoprotein (HDL) cholesterol and the presence of small, dense low-density lipoprotein (LDL) particles, all of which promote atherosclerosis. In this article, we have attempted to present various treatment strategies that include pharmacological interventions such as statins, ezetimibe, PCSK9 inhibitors, fibrates, and omega-3 fatty acids. We have also tried to highlight the pivotal role of lifestyle modifications, including physical activity and dietary changes, in improving lipid profiles and overall cardiovascular health in T2DM individuals. We have also tried to present the latest clinical guidelines for the management of dyslipidaemia in T2DM individuals. In conclusion, the treatment of dyslipidaemia in T2DM individuals is of great importance as it lowers lipid particle levels, slows the progression of atherosclerosis, and ultimately reduces susceptibility to cardiovascular disease.

Type 2 diabetes mellitus (T2DM) is a multisystemic disease with a high global burden and chronic complications. Sexual dysfunction (SD) in patients with T2DM is an often-overlooked complication, despite its high impact on quality of life (QoL). Female sexual disorders can affect women of reproductive age as well as menopausal women. Proposed mechanisms are intertwining a variety of physiological, neurological, vascular, hormonal, and psychological variables. The impairment of sexual function has been linked to hyperglycemia, insulin resistance, chronic low-grade inflammation, endothelial dysfunction, neuropathy, and hormonal abnormalities. There are many different manifestations of female sexual dysfunction, such as insufficient sexual desire, diminished arousal, difficulty in eliciting orgasm, and pain during sexual engagement. Numerous studies have shown that the QoL of patients living with diabetes mellitus (DM) is lower than that of those without DM. SD in women with T2DM leads to deteriorated QoL. Treatment must be individualized based on the diagnosis and the sexual dysfunction as well as underlying medical, psychological, and interpersonal issues. The goal of modern medical care for patients living with diabetes is not to delay death but to improve their health and QoL. The present review article aimed to raise awareness about female sexual dysfunction in patients with T2DM and to provide an overview of its impact on QoL. Full article

An ever-growing body of evidence suggests that sex and gender influence the pathophysiology, incidence, prevalence, clinical manifestations, course, and response to therapy of diabetes. Sex and gender differences are particularly evident in type 1 diabetes, especially in patients using advanced technologies (CGM and AHCL), as they are factors that interact with each other and have an impact on adherence to therapy, which affects not only metabolic compensation, but also, therefore, the prevention of complications and quality of life.

Despite the progress in treatment options and improved understanding of pathophysiology, type 2 diabetes remains one of the costliest and most harmful global chronic diseases. The current guidelines encourage physicians to fight an uphill battle and react to an incubated disease state that has been propelled forward by clinical inertia. The authors completed a literature search of PubMed, ScienceDirect, and NIH, searching with the terms intermittent fasting, type 2 diabetes, and prediabetes, and excluded studies related to religion-based fasting. There is emerging evidence that intermittent fasting could be an option to aid in weight loss, reduce hepatic steatosis, and lower the level of biomarkers such as fasting glucose while improving insulin resistance. If incorporated into the lives of patients with risk factors for type 2 diabetes, intermittent fasting could prove to be a cost-effective and efficient tool for preventing this insidious disease. This clinical review examines current evidence supporting the implementation of this lifestyle to prevent the onset or exacerbation of type 2 diabetes and the hurdles that must still be overcome for physicians to confidently prescribe this to their patients.

In the light of the rapidly increasing global incidence of, and therapeutic arsenal for, diabetes type 2, this brief report underscores the need for advancements in clinical pharmacology and therapeutics (CPT) education with regard to diabetes type 2. We advocate for the comprehensive training of medical students and junior doctors in line with current guidelines, and emphasize the importance of teaching how to draw up individualized treatment plans based on patients’ specific risk factors and conditions, such as cardiovascular risks, weight, and risk of hypoglycaemia. Within the curriculum, traditional teaching approaches should be replaced by innovative methods such as problem-based learning, which has been shown to be more effective in developing prescribing knowledge and skills. The inclusion of real-world experience and interprofessional learning via so-called student-run clinics is also recommended. Subsequently, innovative assessment methods like the European Prescribing Exam and objective structured clinical examinations (OSCE) are highlighted as essential for evaluating knowledge and practical skills. By adopting these educational advances, medical education can better equip future practitioners to adequately manage the complex pharmacological treatment of diabetes. Full article

Aims: To determine the prevalence and predictors of diabetic retinopathy (DR) in Saudi males and females with diabetes. Methods: This cross-sectional study enrolled 507 patients with diabetes between May and August 2018. The data extracted from patients’ records included demographic and clinical information and laboratory investigations. The retinopathy data were based on fundus photography graded into five categories: no DR, NPDR, MNPDR, SNPDR, and PDR. Results: The patients’ mean age was 47.3 years, the majority (59.3%) being female and T2DM being the most common type (52.4%). The prevalence of no DR was 51.4%; NPDR, 4.4%; MNPDR, 7.7%; SNPDR, 3.7%; and PDR, 5.1%. The duration of DM, as well as the severity of hypertension and neuropathy values rose significantly as DR progressed, underlining the pivotal role of hyperglycemia as the primary driver of diabetic complications. The odds ratio for the presence of hypertension was 1.8 (95% CI 0.9–3.5); hypertension showed the highest risk of DR. Stratification according to gender showed a significantly higher DR risk in females than males. Interestingly, nephropathy played a significant role in the DR risk in T1DM. Conclusions: Among T1DM and T2DM patients, the severity of DR is associated with risk factors including the DM duration, hyperglycemia, hypertension, and neuropathy. The impact of these factors varies with gender and diabetes type. Therefore, the severity of DR could define patients at a high risk of macro/microvascular complications and enable earlier interventions to reduce morbidity and mortality among T1DM and T2DM patients.

Alexithymia is the inability to describe one’s own feelings and is being increasingly researched. According to contemporary psychodynamic theories, negative emotions cannot be adequately named and externalized, but remain trapped in the body. Recent research shows the connection of alexithymia with numerous somatic diseases. Diabetes mellitus type 2 and obesity represent great challenges in treatment, and the psychological profiles in these diseases are being studied more and more often. Therefore, alexithymia enters the focus of some research as a factor that could play a significant role in these diseases, namely as the one that makes a difference. The aim of this paper is a review of the literature with the purpose of understanding the current knowledge about the interconnection between alexithymia, obesity and type 2 diabetes mellitus.

Medication adherence (MA) is a major problem. On average 50% of chronic disease management medications are not taken as prescribed While digital healthcare tools like mobile apps offer benefits such as informative messages and prescription management, they must be personalized and offer support across all medication phases to effectively address individual patient factors and optimize adherence, with room for further improvements. This scoping review examined the impact of digital health technologies on MA in adults with diabetes as well as their benefits and barriers. Using PubMed and Scopus databases, 11 out of 385 studies (2.86%) from January 2017 to August 2023 met the criteria for digital health interventions in diabetes MA, assessed through the Chronic Care Model. The Chronic Care Model (CCM) is a patient-centered, evidence-based framework designed to improve the care and outcomes for chronic illness patients, consisting of six core elements and enhanced by eHealth tools that facilitate self-management and support through digital innovations. The results demonstrate the effectiveness of digital health technology in improving medication adherence among adults with diabetes. Specific digital interventions, including mobile apps like Gather and Medisafe, SMS text messaging, telemonitoring, and tailored care management have demonstrated effectiveness in enhancing MA. These interventions have shown positive outcomes, including enhanced glycemic control and increased patient engagement. Some of the limitations, which these technologies face, are the poor usability, digital illiteracy among the patients, low rates of sustainability and low accessibility among the elderly population. Digital health technology shows promise in enhancing medication adherence among adults with diabetes, as revealed in this scoping review. However, ongoing research is necessary to fine-tune these interventions for improved outcomes and the overall well-being of individuals with diabetes. Additional improvement of the technologies and adaptation to the diverse population might be a good field for exploration. Full article

Diabetes is the leading cause of chronic kidney disease (CKD), with nearly half of all cases of kidney failure requiring kidney replacement therapy. While attention is often focused on the profound effects kidney failure has on the quality of life, the principal cause of complications and death among patients with diabetes and CKD is cardiovascular disease (CVD). These risks are often underappreciated by both healthcare professionals and patients. Sodium–glucose cotransporter 2 (SGLT-2) inhibitors were originally developed and approved as glucose-lowering agents for treating type 2 diabetes (T2D). However, agents within the SGLT-2 inhibitor class have since demonstrated robust benefits for CKD, atherosclerotic cardiovascular disease (ASCVD), and heart failure (HF) outcomes. Specifically, dedicated kidney disease and HF outcome trials have shown markedly reduced rates of kidney failure, CVD and HF events, and death among people (with and without diabetes) with CKD. SGLT-2 inhibitors will be used by primary care clinicians, nephrologists, and cardiologists across a range of cardiovascular and kidney conditions and diabetes. Knowledge and awareness of the benefits and key safety considerations, and risk mitigation strategies for these medications is imperative for clinicians to optimize the use of these life-saving therapies.

Diabetes is a chronic, metabolic disease characterized by hyperglycemia, which occurs as a result of inadequate production or utilization of insulin. Type 2 diabetes (T2D) is the most common type of diabetes with estimates projecting a prevalence of more than 1 billion people living with T2DM by 2050. Hence, it was decided to conduct a systematic literature review of health economic evaluations of insulin, the most common medication used for the treatment of the disease, to inform policy. Pharmacoeconomic analyses, written in English and published after 2016, were considered for inclusion. PubMed/Medline, Global Health, Embase and Health Management Consortium were searched separately between 5 July 2023 and 17 July 2023. Grey literature articles were searched on ISPOR and the Cost-Effectiveness Analysis Registry during the same period. After the exclusion criteria were applied, 21 studies were included. Using the BMJ checklist, a quality appraisal was performed on all included studies. Data extraction was performed manually. Regarding evidence synthesis, data were heterogenous and are presented based on study type. The results showed a variety of treatment combinations being available for the treatment of diabetes, with insulin degludec/DegLira and semaglutide being cost-effective despite their high cost, due to the effectiveness of managing the disease. Research around the cost-effectiveness or cost-utility of insulin has potential to progress further, to ensure informed policy-making in the future. Full article

Type 2 diabetes (T2D) poses a growing global health challenge, impacting patients’ and their caregivers’ well-being. This study investigates the influence of T2D complications on caregivers’ quality of life (QoL) using the WHOQOL-BREF questionnaire, accounting for factors like age, disease duration, and control. The research involved 382 T2D patients and 300 caregivers from Vuk Vrhovac University Clinic for Diabetes, Endocrinology, and Metabolic Diseases. The WHOQOL-BREF questionnaire assessed caregivers’ QoL across physical, psychological, social, and environmental domains. Complications, including retinopathy, neuropathy, and kidney disease, were examined for their effects on QoL. Patients’ age impact, gender differences, and disease duration were analyzed. T2D complications had varying impacts on different QoL domains. Caregivers of patients with multiple complications showed significant social functioning impairment. Those without complications reported lower psychological health. Age correlated with poorer physical health scores. Female caregivers rated higher in psychological and environmental health. Disease duration and T2D control had no significant impact on caregiver QoL. Caregivers’ concerns included medication adherence and worry about their partner’s health. This study illustrates the delicate interplay between T2D patients and caregivers, highlighting the multifaceted effects of chronic illness. Comprehensive healthcare techniques that address emotional and social components in addition to medical care are critical for improving the well-being of both patients and their caregivers. The findings contribute to a broader understanding of T2D care dynamics, advocating for empathetic and all-encompassing healthcare practices. Full article

Background and Objectives: Prediabetes is associated with a high risk of developing diabetes and cardiovascular disease. Early treatment with exercise and dietary interventions can reduce the progression of prediabetes to diabetes or even lead to a return of glucose levels to normal. The aim of the study was to evaluate the effect of a dietary supplement with Portulaca oleracea and titrated Cistus creticus extract on the glycemic profile of people with prediabetes. Materials and Methods: Participants were assigned to a dietary supplement with Portulaca oleracea and titrated Cistus creticus extract, along with vitamins and minerals, received once daily for 90 days. Demographics and medical history were obtained, and a complete clinical examination, measurement of somatometric characteristics, and laboratory parameters were performed at baseline. The measurement of somatometric characteristics and laboratory tests were repeated at the end of the study. Results: A total of 26 people with prediabetes participated, 11 females and 15 males. There was a tendency for a decrease in HbA1c after intervention [baseline: 5.9 (5.7–6.1)%; at the end of the study: 5.7 (5.7–6.0)%, p = 0.062] and a significant decrease in fasting glucose levels (from 110.8 ± 7.0 mg/dL to 103.9 ± 10.3, p = 0.005). Fasting insulin and homeostasis model assessment of insulin resistance (HOMA-IR) decreased significantly [baseline fasting insulin: 20.7 (9.3–34.20) μU/mL; at the end of the study: 15.1 (8.6–19.0) μU/mL, p = 0.028; baseline HOMA-IR: 3.6 (2.5–8.9); at the end of the study: 3.5 (2.0–4.6), p = 0.035]. Significant reductions were observed in alkaline phosphatase and uric acid levels. No significant change was observed in body weight, body mass index, or waist circumference after the intervention. No treatment-emergent adverse events were observed, and all participants completed the study. Conclusions: The dietary supplement from Portulaca oleracea and titrated Cistus creticus extract, along with vitamins and minerals, may improve the metabolic profile of people with prediabetes.

There is a correlation between the existence of type 2 diabetes mellitus (T2DM) and the development of thyroid disorders. Prediabetes is a progressive state of moderate insulin resistance that often precedes the onset of T2DM. However, the association between prediabetes and thyroid function is unknown. This study assessed changes in markers of thyroid function in diet-induced prediabetes. Twelve male Sprague Dawley rats (n = 12) were randomly assigned into two groups. Rats in the non-prediabetic (NPD) group were fed a standard rat diet, while rats in the prediabetic (PD) were fed a high-fat high-carbohydrate diet for 20 weeks to induce prediabetes. Thereafter, fasting blood glucose levels were measured. Plasma samples were assessed for triiodothyronine (T3), thyroxine (T4), thyroxine peroxidase (TPO) antibody, insulin, and glycated hemoglobin (HbA1c) concentrations. The elevated blood glucose, HbA1c, and plasma insulin levels coincided with increased T3 and reduced T4 levels in the PD group when compared to the NPD group. There was also an increase in the concentration of TPO antibodies in the PD group. Additionally, there was a significant correlation between the thyroid hormone concentrations and HbA1c levels. In conclusion, these results indicated that there is a positive association between thyroid dysfunction and diet-induced prediabetes in rats. Full article

This study was conducted to determine the barriers to the utilization of diabetic retinopathy (DR) screening in Papua New Guinea (PNG). A list of patients booked for DR screening at Madang Provincial Hospital Eye Clinic (MPHEC) between January 2017 and December 2021 who had not been screened was retrieved, and the patients were invited to participate in the study. The data were collected using a structured questionnaire, and IBM Statistical Package for Social Sciences version 26 was used for the analysis. p < 0.05 was considered statistically significant. One hundred and twenty-nine patients (37.4%) did not attend DR screening for the period under study. The study response rate was 80.6%. The mean ± SD age of the respondents was 51.5 ± 10.9 years. The majority of the study respondents were female (62.5%), people living in rural settings (53.8%), and farmers (22.1%). Time constraints, poor knowledge about DR, and long waiting periods at the DR screening center were the main barriers to the uptake of DR screening. Compared to respondents in urban communities, those in rural settings were significantly concerned about cost (p < 0.001), travel distance to the MPHEC (p < 0.001), and poor information about DR screening (p = 0.002). More than half of the respondents (63.5%) had discontinued using pharmacotherapy for DM. There is a high rate of nonadherence to diabetes (DM) and DR treatment in PNG. There is a need for public health campaigns about DM and strategic DR screening at the community level in PNG and similar countries. Full article

Type 2 diabetes mellitus (T2DM) is a debilitating, lifelong condition with a rising incidence. A wide variety of antihyperglycemic agents are available on the market to treat diabetes. However, the number of patients living with diabetes under suboptimal control remains relatively high. This calls into question whether the application of the current treatment standards is effective and durable to truly manage the disease well. This paper aims to highlight the various classes of antihyperglycemic agents from a pathophysiologic perspective and explore the best possible combination that can have a durable effect on diabetes management. To determine this, an eight-piece pathophysiologic puzzle was created, each piece representing an organ system affected by the disease—liver, pancreas (alpha and beta cells), muscle, adipose tissue, gut, brain, and kidneys. Choosing a combination therapy that is both durable and can effectively address all eight pieces of the puzzle can theoretically create sustainable ameliorating effects. This combination can potentially lead to reduced microvascular and macrovascular complications, as well as work towards creating an ideal long-term, affordable diabetes care plan. Full article
