Plasma Glycated Albumin in Early Pregnancy and Gestational Diabetes Mellitus: A Prospective and Longitudinal Study.

To investigate associations of plasma glycated albumin (GA) concentrations in early and midpregnancy with gestational diabetes mellitus (GDM) risk. We measured GA concentrations using blood samples collected at 10-14 and 15-26 weeks' gestation in 107 GDM case and 214 control participants from the Eunice Kennedy Shriver National Institute of Child Health and Human Development (NICHD) Fetal Growth Study. We performed generalized linear mixed-effect regression to test the mean GA difference between GDM case and control participants and conditional logistic regression to assess prospective associations between GA concentrations and GDM risk. At 15-26 weeks' gestation mean GA was lower in GDM case participants than in control participants (mean 11.90% [95% CI 6.42-32.76] vs. 12.46% [8.45-38.35], adjusted P value for difference = 0.004). Consistently, women with higher GA concentrations tended to have a lower GDM risk, although the associations were not statistically significant. This study suggests that GA concentrations in midpregnancy might be lower in women who later develop GDM. Further studies are needed to identify the mechanism.

Sexual function of overweight pregnant women with gestational diabetes mellitus: A cross-sectional study.

Overweight and obesity are on the rise worldwide and may affect female sexual function. The aim of this study was to investigate the relationship between sexual function in normal and overweight pregnant women with gestational diabetes mellitus (GDM). This cross-sectional study was conducted in overweight and normal-weight pregnant women with GDM in Sari, Iran. Data were collected from 2018 to 2021. The demographic data collected from the participants included age, educational level, occupation, gestational age, duration of marriage, number of births, place of residence (city or village), private house, private bedroom, and insurance status. The General Health Questionnaire, Female Sexual Function Index (FSFI), and Enriched Marital Satisfaction questionnaires were used to assess mental health, sexual functioning, and marital satisfaction, respectively. The study included 200 women with GDM. The mean age of the participants was 29.75 (SD = 4.40) years. Among pregnant women with GDM, 56.50% of them had sexual dysfunction based on FSFI. The mean FSFI score in pregnant women with GDM was 25.60 (SD = 3.61). Among the participants, 50.00% had normal body mass index (BMI). There was no significant difference between BMI status and total sexual function score (p > 0.05). The multivariate analysis revealed that marital satisfaction (β = 0.41, p < 0.001) and BMI status (β = -0.15, p = 0.002) were the only factors significantly associated with overall sexual function, explaining 27% of the variance in the total FSFI score. The results of this study showed that there was no significant relationship between sexual dysfunction and obesity in GDM. Considering that the research in this area is very limited and the negative effects of obesity and GDM have been confirmed in many areas, including sexual desire disorder, necessary planning should be done to control these factors.

Therapeutic Potential of Thunbergia laurifolia L. Extract in Gestational Diabetes Mellitus: Insights from a Rat Model.

To assess the effects of Thunbergia laurifolia L. extract (TLE) on gestational diabetes mellitus (GDM) in a rat model. Thunbergia laurifolin L. leaves were subjected to ethanolic extraction. In vivo study, 50 pregnant rats were randomly divided into 5 groups (10 for each): non-GDM group, GDM induced by streptozotocin (STZ, 60 mg/kg i.p.), metformin (MET) 100 mg/kg, TLE 50, and 500 mg/kg groups. Administration was performed on gestation day 7 until term (day 21). The effects of TLE on blood glucose, insulin levels, lipid profiles, liver enzymes, and maternal performances were assessed. In in vitro study, the effect of TLE was examined using the organ bath for uterine force measurement. In in vivo study, TLE significantly reduced blood glucose as compared to GDM (P<0.05) with gradually increased insulin level. This effect was consistent with islets of Langerhans restoration. Histologically, the uterine muscular layer displayed a marked increase in fiber area in response to both doses as compared to GDM (P<0.05). Additionally, TLE significantly reduced total cholesterol, triglyceride, and alanine transaminase levels (P<0.05). Intriguingly, TLE also led to a notable augmentation in gravid uterus size, live fetuses count, and implantation numbers, while significantly reducing the post-implantation loss rate associated with fetal classification (P<0.05). Thus, GDM improvements were close to those produced by MET. In in vitro study, TLE exerted a concentration-dependent inhibition of spontaneous uterine contractility (half-maximal inhibition concentration=1.2 mg/L). This inhibitory effect extended to potassium chloride depolarization and oxytocin-mediated contractions. When combined with its major constituent, rosmarinic acid, TLE produced an enhanced inhibitory effect (P<0.05). TLE ameliorated blood glucose levels, enhanced uterine muscular structure, and improved maternal and fetal performance in GDM. TLE also displayed tocolytic properties. These findings underscore the need for further exploration of TLE as a potential tocolytic agent to mitigate GDM-associated complications.

P032 THE IMPACT OF NATURE IMMERSION THERAPY ON BLOOD PRESSURE IN HYPERTENSIVE SUBJECTS: A PILOT STUDY

Background and Objective: Conscious nature immersion therapy, termed “Vitamin N”, has shown promise in reducing blood pressure levels in individuals with or without hypertension. This pilot study aims to assess the effect of nature immersion on blood pressure specifically in hypertensive subjects. Methods: A convenience sample of stable hypertensive individuals participated in a standardized 3-hour nature immersion session. Systolic and diastolic blood pressure levels were recorded before the intervention (Phase I), after 30 minutes of the intervention (Phase II), and 48 hours post-intervention (Phase III). Statistical analysis employed a one-way non-parametric ANOVA, Kruskal-Wallis test, and Dunn's post hoc test, with a bilateral significance level of 95%. A criterion of at least 3 mmHg reduction in blood pressure was set for clinical significance. Results Eighteen participants, comprising 12 women (64.67%) and 6 men (33.33%), with a mean age of 60±9.04 years and 61±6.88 years, respectively, were included. Six individuals had a medical history of Diabetes Mellitus Type 2, and one had a history of coronary heart disease. Significant differences in median systolic (MSP) and diastolic pressures (MDP) were observed across the three phases (p&lt;0.05). Notably, Phase II and Phase III showed consistent reductions in blood pressure compared to Phase I, exceeding the established 3 mmHg reduction criterion. Conclusions: Conscious nature immersion therapy (“Vitamin N”) exhibited a significant effect in lowering both systolic and diastolic blood pressure levels among hypertensive individuals. These findings suggest the potential of nature immersion as a non-pharmacological intervention for managing hypertension.

The Impact of Genetic History on the Risk of Developing Type II Diabetes

Type II Diabetes Mellitus (T2DM) is a global health issue with a growing prevalence due to both environmental and genetic factors. Genetic predisposition is a critical determinant of risk, with heritability studies revealing that 40-80% of T2DM risk can be attributed to genetic factors. Key genetic variants, such as those in TCF7L2, PPARG, KCNJ11, and FTO, have been associated with increased risk, impacting pathways related to insulin secretion and resistance. Monogenic forms of diabetes like Maturity-Onset Diabetes of the Young (MODY) highlight the role of single-gene mutations in early-onset diabetes. Familial aggregation studies highlight the significant role of genetic predisposition, with individuals having a family history of T2DM at a markedly higher risk. Epigenetic mechanisms further complicate this risk by introducing heritable changes in gene expression influenced by environmental factors. Genetic testing, including Polygenic Risk Scores (PRS), aids in identifying individuals at increased risk, but their predictive power is limited by the polygenic nature of T2DM. Personalized prevention and management strategies are crucial, utilizing genetic information to tailor interventions and pharmacogenomics to optimize treatment. Culturally sensitive support and education are also essential for managing T2DM. Future research directions include leveraging advanced genomic technologies to further elucidate T2DM’s genetic basis and improve personalized medicine approaches. Keywords: Genetic History, Risk, Type II Diabetes Mellitus.

Abstract P332: High Shared Decision-Making Scores Associated with Blood Pressure Control: The Office Guidelines Applied to Practice (Office-GAP) IMPACT Program

Introduction: Cardiovascular disease (CVD) mortality is higher in people with diabetes mellitus due to the increased prevalence of CVD risk factors. The Office-Gap IMPACT Program (Office-Guidelines Applied to Practice Improving Diabetic Patients’ Adherence to Treatment and Prevention of Cardiovascular Disease) is a patient activation cluster-randomized trial (intervention: Office-GAP + text vs. control: text alone) seeking to improve communication and patient-provider partnerships through patient and provider training in shared decision-making (SDM), use of a guideline-based checklist, and text messaging to improve medication adherence in Federally Qualified Health Care Centers. Hypothesis: We assessed the hypothesis that individual level demographic and clinical characteristics of patients enrolled in Office-GAP IMPACT would be associated with patient-reported SDM using the CollaboRATE 3-item instrument, which measures three core SDM domains: (1) explanation of health issues, (2) elicitation of patient preferences and (3) integration of patient preferences into decisions with a 10-point response scale for each domain ranging from 0 “No effort was made” to 9 “Every effort was made.” Methods: The CollaboRATE was completed three months after baseline. A top-scoring method (a rating of 9 for all three items) was used to dichotomize CollaboRATE responses into two categories - participants who reported the highest levels of SDM on each of the three items versus those who did not. Accounting for the cluster-randomized design, generalized estimating equations (GEEs) were used to compare demographics and baseline factors that may be associated with the outcome. Results: A total of 288 patients were enrolled (intervention, N=158 and control, N=130). Among those with non-missing CollaboRATE scores, 152 (73% ± 3%) had high SDM. The inverse probability of non-missing weighting method was used to account for the missing data in CollaboRATE. Results from the weighted univariable models suggested older patients, history of smoking, and those with BP under control (&lt; 140/90 mmHg) at baseline were more likely to be satisfied with the SDM process. In multivariable logistic regressions, only BP control was statistically significant after adjusting for other factors. Conclusions: In conclusion, participants with BP control had higher SDM scores, which could lead to better health outcomes. Providers should include the practice of SDM principles in every clinical encounter.

Internet Health Resources for Diabetic Foot Search: The Content, Quality, and Readability of Information on Web Sites.

As the incidence of diabetes mellitus increases, the incidence of diabetic foot also increases. This situation, which may lead to devastating complications and progress to limb loss for patients, exposes patients and their social environments to a big crisis. Thus, patients may seek secondary opinions from online sources about information they initially obtained from health institutions. We aimed to evaluate the information content related to diabetic foot on the Internet that is probably used by patients for Internet searching. After software optimization and reset, related queries with the keyword diabetic foot were determined on Google Trends. Selected keywords were searched in three search engines, and the results were examined. Web sites were classified into five subcategories (nongovernmental health institution, governmental institution, academic, blog, and university) and evaluated with an information content scale (ICS) based on the literature, Journal of the American Medical Association benchmark criteria, the Flesch-Kincaid readability test, and presence of the Health On the Net Foundation Code of Conduct certificate. The search engines, keywords, and Web site subcategories were investigated with the evaluation criteria. In terms of finding Web sites eligible for assessment, the Google search engine listed more eligible Web sites than did Bing and Yahoo. Concerning the ICS, there was no significant difference between search engines for total scores (P > .05). Concerning ICS diagnosis and evaluation and ICS total score, academic Web sites scored significantly higher than other subcategories. Results that can be obtained with an Internet search for diabetic foot depend on the proper keyword selection, Web site type, and search engine to help patients reach more appropriate content.

Antiapoptotic and antinociceptive effects of Achillea millefolium L. aqueous extract in rats with experimental painful diabetic neuropathy

Background and purpose: Neuropathy is one of the common complications of diabetes mellitus. This study aimed to determine the analgesic and antiapoptotic effects of the aqueous extract of Achillea millefolium L. (Ach) in rats with experimental painful diabetic neuropathy by behavioral and molecular procedures. Experimental approach: Thirty male Wistar rats were divided into 5 groups including control, diabetes + saline, and diabetes + Ach extract (doses of 150, 300, and 600 mg/kg/day for 3 weeks, orally). A tail-flick test was performed to assess the pain threshold in different groups. Western blotting test was used to evaluate the apoptotic (Bax, Bcl2, cleaved caspase-3, and cytochrome-c) and inflammatory (TNF-α and NF-kB) protein factors in the lumbar portion of the spinal cord tissue. Also, commercial assay kits were used to evaluate oxidative stress factors (MDA, GPx, and SOD enzyme activity) in the lumbar portion of the spinal cord tissue. Findings/Results: Results showed that administering Ach extract at the doses of 300 and 600 mg/kg/day significantly increased the nociception threshold in treated diabetic animals compared to untreated diabetic animals. Moreover, the treatment of diabetic animals with Ach extract (300 and 600 mg/kg/day) significantly reduced the oxidative stress, inflammation, and apoptosis biochemical indicators in the lumbar spinal cord tissue compared to the untreated diabetic group. Conclusion and implications: The findings showed that Ach extract has neuroprotective and anti-nociceptive effects in rats with diabetic neuropathy. The effects can be due to the inhibition of oxidative stress, inflammation, and apoptosis in the spinal cord tissue.

Genetic and Biotechnological Approaches to Gestational Diabetes Mellitus: Advancing Diagnostics, Treatment Strategies, and Public Health Implications.

Background Gestational diabetes mellitus (GDM) is a disorder where pregnant women have difficulty processing glucose, which influences the mother's and the fetus's health. The rising prevalence of GDM, often linked to obesity, highlights the need to study its processes and develop appropriate treatment techniques. Conventional diagnostic approaches may not accurately anticipate or address genetic predispositions, emphasizing the need for further investigation. Objective This study aims to explore genetic and biotechnological approaches to improve diagnostics, treatment, and public health strategies for GDM. Methodology This research was carried out in two hospitals in Pakistan over a period of 12 months, from January to December 2023. A sample size of 260 was determined using an anticipated GDM prevalence of 15%. The data were obtained by administering structured questionnaires, doing anthropometric measures, and analyzing blood samples for genetic information. The statistical study included the use of descriptive statistics, chi-square tests, and logistic regression to examine the relationships between genetic markers and the risk of GDM. The significance level of these associations was assessed using a p-value of <0.05. Results Among the 260 individuals with GDM included in the research, 52 (20.00%) and 73 (28.08%) patients had the TCF7L2 risk variation. The study found that the TCF7L2 and FTO risk polymorphisms were linked to a higher likelihood of developing GDMamong the participants. The association was statistically significant, with p-values of 0.012 and 0.045, respectively. Logistic regression analysis showed that the TCF7L2 risk variant had an odds ratio of 2.35 (95% confidence interval [CI]: 1.21-4.56, p = 0.012), while the FTO risk variant had an odds ratio of 1.97 (95% CI: 1.05-3.70, p = 0.045). There is a substantial association between consuming a large amount of sugar (OR: 2.10, 95% CI: 1.15-3.82, p = 0.017) and engaging in little physical activity (OR: 1.85, 95% CI: 1.07-3.22, p = 0.025) and an increased risk of GDM. Treatment brought the glucose levels of people with GDM down to normal in 68.49% of cases. Conclusion Integrating genetic screening for TCF7L2 and FTO variants with lifestyle modifications may enhance early detection and personalized management of GDM, leading to improved maternal and fetal health outcomes.

The association between dietary patterns before pregnancy and gestational diabetes mellitus: a matched case-control study in China.

We aimed to explore the relationship between dietary patterns and gestational diabetes mellitus (GDM) during pre-pregnancy six months using principal component analysis (PCA) and the geometric framework for nutrition (GFN). We conducted a case-control study that included 210 GDM pregnant women and 210 controls. The dietary intake of all participants was assessed by a validated semi-quantitative food frequency questionnaire (FFQ). Major dietary patterns were extracted by PCA. A conditional logistic regression model was used to determine whether specific dietary patterns are associated with the risk of GDM. Meanwhile, the relationship between dietary patterns and GDM was visualized using GFN. Four major dietary patterns were identified: "protein-rich pattern," "plant-based pattern," "oil-pickles-desserts pattern," and "cereals-nuts pattern." After adjustment for confounders, the "plant-based pattern" was associated with decreased risk of GDM (Q4 vs. Q1: OR = 0.01, 95% CI: 0.00-0.08), whereas no significant association was found in other dietary patterns. Moreover, there was no dietary intake of ice cream cones and deep-fried dough sticks for the population, which would produce fewer patients with GDM. Deep-fried dough sticks had statistically significant differences in the case and control groups (p < 0.001), while ice cream cones had the opposite result. The "plant-based pattern" may reduce the risk of GDM. Besides, although the "cereals-nuts pattern" had no association with GDM risk, avoiding the intake of deep-fried dough sticks could decrease GDM risk.

Predictors for major adverse cardiovascular events among patients with acute coronary syndrome in Bosnia and Herzegovina.

Despite advancements in the diagnosis, treatment and monitoring of patients with acute coronary syndrome (ACS), morbidity and mortality following ACS remain high. The aim of this study was to actively seek possible predictors of adverse outcomes after ACS aiming to identify high-risk patients promptly. This retrospective cohort study investigated patients with ACS hospitalized at Clinical Centre of the University of Sarajevo from 2019 to 2021. Patients were followed up for a period of 12 months post-discharge to assess major cardiovascular events (MACE) and MACE associated independent predictors. The study included 121 patients, mostly male 102 (84.3%), with a mean age of 60.83±12.61 years; prevalent risk factors were hypertension 94 (77.7%), dyslipidaemia 84 (69.4%), diabetes mellitus 91 (75.2%), active smoking 67 (55.4%) and positive family history of cardiovascular diseases 81 (66.9%). MACE occurred in 33 (27.3%) patients since the initial ACS, and those patients were older (p=0.012), had higher level of creatinine (p<0.001), lower ejection fraction at discharge (p<0.001) and larger left atrial diameter (p=0.032). Serum creatinine (OR=1.014, 95% CI 1,003-1,026, p=0.017) and ejection fraction (OR=0.924, 95% CI 0,869-0,984, p=0.013) were independent predictors associated with a 12-month follow up MACE following ACS. Monitoring of serum creatinine level, left atrial diameter, and ejection fraction post-acute coronary syndrome as potential indicators of future MACE within a 12-month follow-up period is of great importance. These findings emphasize the need for tailored management strategies to mitigate risks in this patient population.

Using inflammatory biomarkers in early pregnancy to predict subsequent antenatal depression

BackgroundAntenatal depression (AD) is one of the most common pregnancy complications. Recent studies indicated that immune responses during pregnancy may contribute to development of AD. ObjectivesThis study aimed to identify possible inflammatory biomarkers in early pregnancy to predict maternal depressive symptoms before delivery. MethodsThis case-control study was conducted within the Maternal and Infant Health (MI-Health) birth cohort (Beijing, China) and depressive symptoms were assessed by Zung Self-rating Depression Scale (SDS) in both second and third trimesters. By using immune multi-factors kits, we tested 26 inflammatory factors in the serum of 38 cases with antenatal depression symptoms in both trimesters (SDS ≥ 53) and 38 controls. Logistic regression was used to identify candidate biomarkers, and the predictive capabilities were evaluated by using Receiver Operator Characteristics (ROC) analysis. ResultsThe concentrations of ln(CCL24) (p = 0.020), IL-7 (p = 0.006) and IL-10 (p = 0.014) were higher in early pregnancy among women with depressive symptoms comparing to healthy controls. The difference remained statistically significant after adjusting for maternal age, education level, gestational diabetes mellitus, pre-pregnancy BMI and gestational weeks of blood sampling (OR(ln(CCL24)) = 4.625, OR(IL-7) = 1.414, OR(IL-10) = 1.151). In ROC analysis, ln(CCL24), IL-7, and IL-10 achieved discrimination for depressive symptoms antepartum, with the values of AUC estimated at 0.75. LimitationsThe sample size is limited, and the infectious disease infection records were not collected for control. ConclusionHigher levels of CCL24, IL-7 and IL-10 may indicate the higher risk of antenatal depression and are potential biomarkers indicating pathogenesis of antenatal depression.

Clopidogrel therapy in nonischemic central retinal vein occlusion: A case report and therapeutic insight

Abstract: Central retinal vein occlusion (CRVO) is a significant cause of vision impairment in adults, often associated with various systemic and ocular risk factors. The current literature presents a limited understanding of the efficacy of antithrombotic agents in CRVO management, with sparse comparative studies evaluating the effectiveness of different antiplatelet therapies. Here, we report the case of nonischemic CRVO in a 54-year-old male with multiple systemic comorbidities, including diabetes mellitus, hypertension, and dyslipidemia. Initial treatment with aspirin 100 mg daily resulted in worsening visual acuity (VA) and retinal pathology, prompting a transition to clopidogrel 75 mg daily due to patient refusal of intravitreal injection. Remarkably, clopidogrel therapy led to rapid and sustained improvement in VA, macular edema resolution, and complete resolution of retinal vascular pathology within weeks. This case underscores the therapeutic potential of clopidogrel in nonischemic CRVO management, suggesting its superiority over aspirin in select patients. We discuss the mechanisms underlying the differential efficacy of antiplatelet agents and highlight the need for further comparative studies to guide optimal treatment strategies in CRVO.

Exploring the Biological Effects of Anti-Diabetic Vanadium Compounds in the Liver, Heart and Brain.

The prevalence of diabetes mellitus and diabetes-related complications is rapidly increasing worldwide, placing a substantial financial burden on healthcare systems. Approximately 537 million adults are currently diagnosed with type 1 or type 2 diabetes globally. However, interestingly, the increasing morbidity rate is primarily influenced by the effects of long-term hyperglycemia on vital organs such as the brain, the liver and the heart rather than the ability of the body to use glucose effectively. This can be attributed to the summation of the detrimental effects of excessive glucose on major vascular systems and the harmful side effects attributed to the current treatment associated with managing the disease. These drugs have been implicated in the onset and progression of cardiovascular disease, hepatocyte injury and cognitive dysfunction, thereby warranting extensive research into alternative treatment strategies. Literature has shown significant progress in utilizing metal-based compounds, specifically those containing transition metals such as zinc, magnesium and vanadium, in managing hyperglycaemia. Amongst these metals, research carried out on vanadium reflected the most promising anti-diabetic efficacy in cell culture and animal studies. This was attributed to the ability to improve glucose management in the bloodstream by enhancing its uptake and metabolism in the kidney, brain, skeletal muscle, heart and liver. Despite this, organic vanadium was considered toxic due to its accumulative characteristics. To alleviate vanadium's toxic nature while subsequently manipulating its therapeutic properties, vanadium complexes were synthesized using either vanadate or vanadyl as a base compound. This review attempts to evaluate organic vanadium salts' therapeutic and toxic effects, highlight vanadium complexes' research and provide insight into the novel dioxidovanadium complex synthesized in our laboratory to alleviate hyperglycaemia-associated macrovascular complications in the brain, heart and liver.

Evaluations of the in vitro and in vivo antidiabetic activity of 70 % ethanolic fruit extracts of Rosa abyssinica

BackgroundDiabetes mellitus is becoming major health challenge with continually increasing burden. High costs of conventional medicines and numerous side effects associated with them, on the other hand, easy availability and accessibility of traditional herbal medicines calls upon experimental investigations to validate their effect on lowering blood glucose level. MethodsThe dried fruit of Rosa abyssinica was macerated with 70 % ethanol and the extract's in vitro antidiabetic activity was investigated using dinitrosalisylic acid method for alpha amylase inhibitory activity. Furthermore, the in vivo hypoglycemic and Antihyperglycemic effects of various doses of the extract (100, 200 and 400 mg/kg) was determined on normoglycemic, glucose loaded (1500 mg/kg) and Streptozotocine (180 mg/kg)-induced diabetic mice models. ResultsThe acute oral toxicity study revealed the plant showed no toxic effect on swiss albino mice at 2000 mg/kg. The in vitro alpha amylase inhibitory activity study showed that the extract has comparable IC50 value of 21.37 ± 4.252 μg/ml with the standard drug acarbose (IC50 value of 26.72 ± 3.59 μg/ml). On the other hand, in normal mice, none of the dose levels except at 400 mg/kg significantly reduces blood glucose level. This is in contrast to the oral glucose tolerance test, which the extract produced significant reduction at 60, 90 and 120 min following glucose challenge. The 70 % ethanolic fruit extracts of Rosa abyssinica also experienced profound antidiabetic activity in streptozotocin-induced diabetic model. In the single-dose study, both RAFE200 and RAFE400 demonstrated a significant (P˂0.05) reduction in blood glucose levels at 1, 2, 3, and 4 h. Similarly, in the repeated-dose study, RAFE200 and RAFE400 not only significantly reduced blood glucose levels but also produced a notable improvement in animal body weight. ConclusionThe 70 % ethanolic fruit extracts of Rosa abyssinica have shown significant in vitro alpha amylase inhibition effect and an in vivo blood glucose level lowering effects in diabetic mice.Therefore, this study supports the traditional use of Rosa abyssinica in the management of diabetes mellitus.

Synthesis and Characterization of Baicalein-loaded Aquasomes: An In vitro and In silico Perspective for Diabetes Mellitus.

Millions of individuals worldwide suffer from metabolic abnormalities induced by diabetes. Baicalein, a flavonoid, has shown several properties in various treatments with potential properties, including anti-inflammatory, antioxidant, and anti-diabetic properties. Practically, its application is hindered due to low solubility in aqueous media. Overcoming this challenge, aquasomes can offer an effective approach for delivering drugs and bioactive molecules to target various diseases. The study aimed to develop and evaluate baicalein-loaded aquasomes for improving solubility and comparing their antidiabetic properties to acarbose through in silico docking. Baicalein-loaded aquasomes were prepared through a three-step process: core preparation, lactose coating, and drug loading. The evaluation included assessing particle size, drug-excipient interactions, drug entrapment efficiency, loading capacity, in vitro drug release, and the kinetics of drug release. In silico docking and in vitro α-amylase inhibition activity was evaluated to assess the anti-diabetic potential of baicalein. The baicalein-loaded aquasomes were spherical with sizes ranging from 300-400 nm. FTIR analysis indicated no interaction between the components. The formulation exhibited drug entrapment efficiency of 94.04±0 4.01% and drug loading of 17.60 ± 01.03%. Drug release study showed sustained and complete (97.30 ± 02.06%) release, following first-order kinetics. Docking analysis revealed comparable binding affinity to acarbose, while the α-amylase inhibition assay showed greater inhibition potential of the aquasomes compared to the baicalein solution. Aquasomes offer an alternative approach to conventional delivery methods. The selfassembling characteristics of aquasomes greatly simplify their preparation process, adding to their appeal as a drug delivery system.

Changes of m6A Regulatory Proteins and Nrf2 Signaling Molecules in Liver Tissue of Type 2 Diabetes Mellitus Rats.

Both dysregulation of N6-methyladenosine (m6A) regulatory proteins and Nrf2 signaling molecules are involved in the process of injury to multiple tissues. However, changes of m6A regulatory proteins and Nrf2 signaling molecules in liver tissue of T2DM remain unclear. In present study, changes of m6A regulatory proteins (Mettl3, Mettl16, Fto, Alkbh5 and Ythdc2) and Nrf2 signaling molecules (Nrf2, Sod1, Ho-1, Gclc) were detected in the liver tissues of T2DM rats, which constructed by high fat-diet feeding and intraperitoneal injection of streptozotocin. Our results indicated that the morphology of liver tissues from T2DM rats showed obvious abnormalities, as well as levels of liver function indicators and expressions of Nrf2 signaling molecules Nrf2, Sod1, Ho-1 were significantly increased in T2DM rats when compared with those in corresponding control rats. More importantly, m6A regulatory proteins such as Mettl3, Mettl16, Fto, Alkbh5 and Ythdc2 were dramatically higher than those in control rat. In a word, m6A regulatory proteins and Nrf2 signaling molecules may significantly change in liver tissue of T2DM rats. And This provides clues and ideas for the study of liver injury in T2DM from the perspective of RNA epigenetics in the future.

Inflammatory indices-Systemic Immune-Inflammation Index (SII) and Systemic Inflammatory Response Index (SIRI)-during Pregnancy and Associations with Gestational Diabetes Mellitus.

Gestational diabetes mellitus (GDM) is a prevalent complication during pregnancy. This study aimed to explore the associations between inflammatory indices during pregnancy and the development of GDM. Data from the Fujian Birth Cohort Study between March 2019 and December 2022 were used. Participants who delivered a live-born singleton were included and categorized into GDM and non-GDM groups. Two inflammatory indices, the systemic immune-inflammation index (SII) and systemic inflammatory response index (SIRI), were calculated for each trimester of pregnancy via hematological parameters from complete blood count tests. The distributions of inflammatory indicators across trimesters were compared between the GDM and non-GDM groups. Additionally, multivariable logistic regression models were employed to investigate the associations between inflammatory indices and the incidence of GDM. A total of 17297 participants were included, 21.2% of whom were diagnosed with GDM. In the first trimester, the median SIIs for the GDM and non-GDM groups were 817.7×109/L and 756.9×109/L, respectively, whereas the median SIRIs were 1.6×109/L and 1.5×109/L, respectively. In both groups, the SII increased to its peak in the second trimester before declining, whereas the SIRI progressively increased throughout pregnancy. The SII and SIRI were greater in the GDM group than in the non-GDM group during the first two trimesters but lower in the third trimester. Nonlinear positive associations between first-trimester SII and SIRI levels and GDM were observed, with extreme quartile odds ratios of 1.32 (95% CI: 1.19, 1.48) and 1.39 (95% CI: 1.24, 1.55), respectively. The SII and SIRI increased and reached their peak values in the second and third trimesters of pregnancy, respectively. Elevated levels of the SII and SIRI in early pregnancy were linked to an increased risk of GDM, suggesting their potential utility as screening tools for GDM.
