Downregulation of Tnf-α and Cat Expression in a Wistar Rat Diabetic Model during Diabetes Onset
IntroductionDiabetes Mellitus (DM) is a metabolic disorder characterized by persistent hyperglycemia and/or insulin resistance. If left uncontrolled, it can lead to a combination of cardiac and renal alterations known as cardiorenal syndrome. Additionally, oxidative stress and inflammation contribute to tissue damage, thereby reducing the life expectancy of individuals with diabetes.
AimThe aim of this study was to identify early molecular markers associated with cardiorenal syndrome, oxidative stress, and inflammation, and to investigate their correlation with the duration of exposure to DM.
MethodsAn experimental DM model was employed using Wistar rats. The rats were divided into four groups: diabetic rats at 7 days (DM7), diabetic rats at 30 days (DM30), control sham at 7 days (CS7), and control sham at 30 days (CS30). Blood and brain tissue from the brainstem region were collected at 7 and 30 days after confirming DM induction. Gene expression analysis of Bnp, Anp, Cat, Gpx, Sod, Tnf-α, and Il-6 was performed.
ResultsThe analysis revealed lower expression values of Cat in the brainstem tissue of the DM7 group compared to the NDS7 group. Moreover, diabetic animals exhibited statistically lower levels of Tnf-α in their peripheral blood compared to the control animals.
ConclusionThis study concluded that DM alters the oxidative balance in the brainstem after 7 days of DM induction, resulting in lower Cat expression levels. Although some genes did not show statistical differences after 30 days of DM induction, other genes exhibited no expression values, indicating possible gene silencing. The study identified an imbalance in the studied pathways and concluded that the organism undergoes a compensatory state in response to the initial metabolic alterations caused by DM.

Impaired Fibroblast Growth Factor 21 (FGF21) Associated with Visceral Adiposity Leads to Insulin Resistance: The Core Defect in Diabetes Mellitus
Authors: Unnati Jain, Priyanka Srivastava, Ashwani Sharma, Subrata Sinha and Surabhi JohariThe Central nervous system (CNS) is the prime regulator of signaling pathways whose function includes regulation of food intake (consumption), energy expenditure, and other metabolic responses like glycolysis, gluconeogenesis, fatty acid oxidation, and thermogenesis that have been implicated in chronic inflammatory disorders. Type 2 diabetes mellitus (T2DM) and obesity are two metabolic disorders that are linked together and have become an epidemic worldwide, thus raising significant public health concerns. Fibroblast growth factor 21 (FGF21) is an endocrine hormone with pleiotropic metabolic effects that increase insulin sensitivity and energy expenditure by elevating thermogenesis in brown or beige adipocytes, thus reducing body weight and sugar intake. In contrast, during starvation conditions, FGF21 induces its expression in the liver to initiate glucose homeostasis. Insulin resistance is one of the main anomalies caused by impaired FGF21 signaling, which also causes abnormal regulation of other signaling pathways. Tumor necrosis factor alpha (TNF-α), the cytokine released by adipocytes and inflammatory cells in response to chronic inflammation, is regarded major factor that reduces the expression of FGF21 and modulates underlying insulin resistance that causes imbalanced glucose homeostasis. This review aims to shed light on the mechanisms underlying the development of insulin resistance in obese individuals as well as the fundamental flaw in type 2 diabetes, which is malfunctioning obese adipose tissue.

Dating Violence, Lifestyle and Risk of Type 2 Diabetes in Mexican Women University Students
BackgroundDating violence is a prevalent issue among Mexican women, as is the incidence and prevalence of Type 2 diabetes mellitus (T2DM). The effects of dating violence can negatively impact lifestyle and, consequently, increase the risk of T2DM.
ObjectiveThis study aimed to explore the influence of dating violence on lifestyle and the risk of T2DM in women university students from Mexico.
MethodsThe study employed a cross-sectional and correlational design. The study population consisted of women university students. The sample size included 255 participants. Women aged 18 to 39 with current dating relationships and residency in Mexicali, Baja California, Mexico, were included. Data collection was conducted from February to May 2023. Correlations and multiple linear regression models were conducted.
ResultsA total of 255 women participated, with an average age of 21.6 years (SD = 3.2), and 32.2% had a history of intrafamily violence during childhood. 58.8% of the participants exhibited some level of risk of T2DM, and 56.7% of the lifestyle was mostly categorized as poor/fair. Detachment was the most prevalent type of dating violence, followed by coercion. Dating violence was correlated with lifestyle (r = -.430) and the risk of T2DM (r = .321). In the multiple linear regression model, dating violence influenced the risk of T2DM.
ConclusionWomen who reported higher levels of dating violence have a less healthy lifestyle and a greater risk of T2DM. It is important to consider dating violence to improve lifestyle and prevent T2DM in Mexican women university students.

Conceptual Overview of Prevalence of Prediabetes
Authors: Monika, Pragi Arora, Varun Kumar and Pankaj PopliPrediabetes increases the risk of type 2 diabetes, metabolic syndrome, chronic renal disease, and cardiovascular disease in a person. In current practice, five alternative definitions of prediabetes are utilized, each based on different HbA1c, fasting glucose, and 2-hour glucose cut points. Prediabetes is a common condition that occurs between normal glycemia and diabetes. It is more common in elderly and obese people. The prevalence of prediabetes and diabetes can be influenced by a variety of individual, family, and societal variables. Additionally, as diabetes is the primary contributor to non-communicable diseases (NCD), it is crucial to identify the key temporal variables for diabetes early diagnosis. In turn, effective prediabetes and diabetes awareness, control, and preventive programs may be created by policymakers and public health professionals worldwide. Popular pathogenic pathways in prediabetes include insulin resistance, inflammation, and sensitivity to insulin. HBA1c, OGTT, and FPG are discussed as the diagnostic criteria in order of frequency. The most commonly researched therapies in the realm of prediabetes are metformin, exercise, and physical activity. Physiological markers including BMI, blood pressure, and waist circumference prompted relatively significant concern. Despite declining trends, the study demonstrates that prediabetes and diabetes are widely prevalent. In order to prevent non-communicable illnesses, the research suggests encouraging healthy lifestyles and regular screenings.

Analytical and Bioanalytical Methods for the Determination of Dipeptidyl Peptidase-4 Inhibitors in Various Matrices: A Comprehensive Review
Authors: Sakshi Hadawale and Sanjay SharmaBackgroundDPP-4 inhibitors, or gliptins, are new oral antidiabetic drugs for type 2 diabetes. They help to regulate insulin and glucagon. These drugs have the advantage of a lower risk of hypoglycemia compared to some other diabetes medications and are typically prescribed when metformin and sulphonylureas have become less effective.
ObjectiveThis review analyses a range of analytical and bioanalytical methods for DPP-4 inhibitors, that use spectroscopic techniques, chromatographic, and hyphenated techniques for analysis. So far, no review comprising all DPP-4 inhibitors has been presented. The primary objective of this review is to present the analysts with various analytical and bioanalytical methods for the quantification and estimation of DPP-4 inhibitors in different matrices.
MethodsTo improve understanding, a review was carried out by creating a database of pre-existing research from digital sources such as ScienceDirect, and PubMed. The methodology is shown in the flowchart of the literature selection process.
ConclusionThe comprehensive assessment of methods for analysing DPP-4 inhibitors can be a valuable resource for researchers and healthcare practitioners. Hitherto, no review encompassing all DPP-4 inhibitors has been presented. Therefore, gaps in the data available on a particular subject, need to be required to collect data on a particular construct. The review suggests that chromatographic techniques were majorly used for analysis wherein solvents like acetonitrile, methanol, and buffer solutions were used as mobile phases that can deteriorate HPLC columns and equipment. So, scientists could investigate new methods for the assessment of DPP-4 inhibitors using more eco-friendly solvents.

Risk of Type 1 Diabetes Mellitus in SARS-CoV-2 Patients
Authors: Shweta Chahal, Rojin G. Raj and Ranjeet KumarRecent studies have found that a link between people with type 1 diabetes mellitus (T1DM) are at higher risk of morbidity as well as mortality from COVID-19 infection, indicating a need for vaccination. T1DM appears to impair innate and adaptive immunity. The overabundance of pro-inflammatory cytokines produced in COVID-19 illness that is severe and potentially fatal is known as a “cytokine storm.” Numerous cohorts have revealed chronic inflammation as a key risk factor for unfavorable COVID-19 outcomes. TNF-α, interleukin (IL)-1a, IL-1, IL-2, IL-6, and other cytokines were found in higher concentrations in patients with T1DM. Even more importantly, oxidative stress contributes significantly to the severity and course of COVID-19's significant role in the progression and severity of COVID-19 diseases. Severe glucose excursions, a defining characteristic of type 1 diabetes, are widely recognized for their potent role as mediating agents of oxidative stress via several routes, such as heightened production of advanced glycation end products (AGEs) and activation of protein kinase C (PKC). Furthermore, persistent endothelial dysfunction and hypercoagulation found in T1DM may impair microcirculation and endothelium, which could result in the development of various organ failure and acute breathing syndrome.

Probiotic Supplementation during Pregnancy: Evaluating the Current Clinical Evidence against Gestational Diabetes Mellitus
BackgroundGestational diabetes mellitus (GDM) constitutes a common metabolic disorder that could lead to deleterious short- and long-term complications in both the mother and her infant. Probiotic supplementation seems to exert diverse, healthy effects by acting as a preventive agent against various human diseases, including GDM.
ObjectiveThe purpose of the current narrative review was to critically summarize and scrutinize the available clinical studies during the last 15 years (2008-2023) concerning the use of probiotic supplementation during pregnancy as a protecting agent against GDM.
MethodsA thorough and in-depth search was performed in the most accurate scientific databases, e.g., PubMed., Scopus, Web of Science, and Google Scholar applying effective, and relevant keywords.
ResultsThere are currently some clinical studies suggesting the potential beneficial impact of probiotic supplementation in the prevention and/or co-treatment of GDM. Nevertheless, there is a high heterogeneity amongst the available clinical studies concerning the dosage, the administration duration, the probiotic species types, the method designs and protocols, and the study populations.
ConclusionProbiotic supplementation at conventional dosages and in combination with a balanced healthy diet, and lifestyle seems to reduce the the risk of developing GDM, while ameliorating the severity of its symptoms. Further clinical studies taking into account the above considerations should be performed to establish conclusive results, while the future meta-analyses should include studies with the feasibly lowest heterogeneity.
