Abstract
PURPOSE OF REVIEW Diabetes mellitus (DM) is a group of metabolic illnesses characterized by elevated levels of glucose in the bloodstream as a result of abnormalities in the generation or function of insulin. Medical Nutrition Therapy (MNT) is an essential component of diabetes management. Dietary fats are essential in both the prevention and progression of chronic diseases. Omega-3 polyunsaturated fatty acids are recognized for their advantageous impact on health. They assist in controlling blood sugar levels and lipid profile in patients with all types of diabetes. Furthermore, they reduce the occurrence of cardiovascular events and death linked to DM. RECENT FINDINGS After evaluating the antioxidant, anti-inflammatory, antilipidemic, and antidiabetic mechanisms of omega-3 fatty acid supplements, as well as the results from randomized controlled studies, it is clear that these supplements have positive effects in both preventing and treating diabetes, as well as preventing and treating complications related to diabetes, specifically cardiovascular diseases. However, current evidence does not support the use of omega-3 supplementation in people with diabetes for the purpose of preventing or treating cardiovascular events. People with all types of diabetes are suggested to include fatty fish and foods high in omega-3 fatty acids in their diet twice a week, as is prescribed for the general population.

[PMID: 39157744 PMCID: PMC11328849 DOI: 10.2147/idr.s474453] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/11/2024] [Accepted: 08/02/2024] [Indexed: 08/20/2024] Open
Abstract
Background Gestational Diabetes Mellitus (GDM) significantly increases the risk of adverse pregnancy outcomes, including elective pre-labor cesarean deliveries. Postoperative surgical site infections (SSIs) pose a significant concern, underscoring the need for a detailed investigation into their causes and preventative measures. The aim of this study is to systematically identify and analyze the microbial etiology and antimicrobial resistance profiles of pathogens responsible for SSIs in GDM patients undergoing elective pre-labor cesarean deliveries. Additionally, this research aims to elucidate the risk factors contributing to SSIs, with a specific focus on operation duration, amniotic fluid contamination, and genital tract inflammation, and their correlation with the incidence of SSIs. Methods A retrospective analysis was conducted at our Hospital between September 2018 and July 2023, involving 150 GDM patients who underwent elective pre-labor cesarean deliveries. Patients were categorized into infected and uninfected groups based on postoperative SSIs. Clinical data were meticulously collected and analyzed using SPSS software (version 27.0). Independent sample t-tests and chi-square tests were employed for statistical analysis. Results Microbial profiling revealed that Gram-negative bacteria, primarily E. coli, constituted approximately 59.46% of the isolated strains, exhibiting significant resistance to commonly used antibiotics such as ampicillin and cefotaxime. Elevated levels of biomarkers, including Procalcitonin (PCT) and Hemoglobin A1c (HbA1c), were significantly associated with SSIs. Multivariate logistic regression analysis identified operation time ≥1-hour, amniotic fluid contamination, and genital tract inflammation as significant risk factors. Conclusion This study highlights the microbial etiology, resistance patterns, and risk factors for SSIs in GDM cesarean patients, emphasizing the need for tailored preoperative evaluations.

Abstract
Background: Cod liver oil has anti-inflammatory properties and could help regulate recurrent aphthous stomatitis (RAS). An orthogonal experiment was used to evaluate and improve the dosage form of compound cod liver oil, which has replaced the previously used liniment preparation based on film method. Methods: An orthogonal experiment was adopted, and the appearance and film-forming time of the film coating agents were used as indicators. The optimal ratio in the preparation process for the compound cod liver oil film agent was then optimized. A method for determination of compound cod liver oil film was established using High-Performance Liquid Chromatography (HPLC). Results: The results indicate that the blank films prepared using 55 mg polyvinyl alcohol (PVA) (PVA low), 45 mg of PVA (PVA medium), and 10 mg glycerol had the optimal performance, which was defined as PVAa. The drug-carrying film prepared from 3 mL PVAa (i.e., film-forming material with the optimal proportion), 30 mg dexamethasone acetate, and 30 mg metronidazole had the optimal performance. The verified sample has a complete and smooth appearance, uniform thickness and color, and no evident bubbles, which meets the requirements for a film agent defined in the Chinese Pharmacopoeia, 2020 edition. HPLC was used to determine the major components: dexamethasone acetate, metronidazole, and dyclonine hydrochloride, and the optimal separation effect was obtained. The method has advantages of good specificity, good linear results, high recovery rate, and good repeatability. Conclusion: This study proposes an optimized compound cod liver oil film former agent and preparation method. The results indicate that the compound cod liver oil film former agent had good performance, reflecting the high feasibility of this research method. The detection method of compound cod liver oil film was established by HPLC. The method was feasible, and the validity and stability of the formulation and preparation technology were guaranteed. The role of the newly developed agent in patients with RAS should be investigated further.

Abstract
CONTEXT Pregnant women have physiological metabolic changes in glycemic and lipid profiles that are essential for fetal development. OBJECTIVE The aim of this systematic review was to analyze the effects of fish-oil-capsule supplementation on the glycemic and lipid profiles of pregnant women. DATA SOURCES A systematic search was conducted of the MEDLINE (by PubMed), Embase, Cochrane Library (CENTRAL) databases and gray literature, including preprints for all relevant studies published in English, with no date restrictions. DATA EXTRACTION The estimated pooled results were analyzed using a random-effects model and represented by mean differences (MDs) and corresponding 95% confidence intervals (CIs). The analyses were performed with R software, version 4.2.1, using the "Meta" packages, versions 6.0-0. DATA ANALYSIS Fifteen eligible studies were included after screening. In a pooled analysis, overall fish-oil supplementation had no effect on parameters compared with placebo. In the subgroup analysis, fish-oil supplementation may be beneficial in insulin (MD: -2.11 IU/mL; 95% CI: -3.86, -0.36) and homeostasis model assessment of insulin resistance (HOMA-IR) (MD: -0.71; 95% CI: -1.14, -0.29) indices, with heterogeneity (I2 =0%) among pregnant women with diabetes mellitus. In the subgroup with doses of eicosapentaenoic acid (EPA) below 200 mg, there was a reduction in HOMA-IR in the intervention group (MD: -0.60; 95% CI: -1.14, -0.06). CONCLUSION Pregnant women taking fish-oil capsules showed significant beneficial changes in the subgroups of type 2 diabetes and EPA dosages below 200 mg for insulin and HOMA-IR.

Abstract
Docosahexaenoic acid (DHA) supplementation is recommended for women during pregnancy because of its neurological, visual, and cognitive effects. Previous studies have suggested that DHA supplementation during pregnancy may prevent and treat certain pregnancy complications. However, there are contradictions in the current related studies, and the specific mechanism by which DHA acts remains unclear. This review summarizes the research on the relationship between DHA intake during pregnancy and preeclampsia, gestational diabetes mellitus, preterm birth, intrauterine growth restriction, and postpartum depression. Furthermore, we explore the impact of DHA intake during pregnancy on the prediction, prevention, and treatment of pregnancy complications as well as its impact on offspring neurodevelopment. Our results suggest that there is limited and controversial evidence for the protective effect of DHA intake on pregnancy complications, with the exception of preterm birth and gestational diabetes mellitus. However, additional DHA supplementation may improve long-term neurodevelopmental outcomes in the offspring of women with pregnancy complications.

Abstract
To analyze endocrine characteristics and risk factors of type 2 diabetes mellitus (T2DM) gastrointestinal autonomic neuropathy. A total of 202 patients with T2DM with obesity who were hospitalized at our institute between January 2019 and June 2021 were selected. Based on adrenocorticotropic hormone (ACTH) levels, 102 patients were placed in the ACTH abnormal group and 100 patients were placed in the non-ACTH abnormal group. Ninety-five healthy adults without diabetes, hyperlipidemia, osteoporosis, or endocrine system abnormalities who were examined at our hospital during the same period were selected as the control group. Fasting plasma glucose (FPG), fasting insulin (FINS), triglycerides (TG), total cholesterol (TC), homeostasis model assessment of insulin resistance (HOMA-IR), ACTH level, body mass index (BMI), and bone mineral density (BMD) were measured to evaluate endocrine characteristics and risk factors. BMI, FPG, FINS, HOMA-IR, TG, TC, and ACTH levels in the abnormal ACTH group were significantly higher than those in the other 2 groups, while BMD was significantly lower than that in the other 2 groups (all P < .05). BMI, FPG, FINS, HOMA-IR, TG, TC, and ACTH in the non-ACTH abnormal group were significantly higher than those in the control group, whereas BMD was significantly lower than that in the control group (all P < .05). The plasma ACTH level in patients with abnormal ACTH levels was significantly positively correlated with BMI, FPG, FINS, HOMA-IR, TG, and TC and negatively correlated with BMD (all P < .05). Multivariate regression analysis showed that BMI, advanced age, FINS, TG, and FPG were risk factors for ACTH abnormalities in patients with diabetes (odds ratio > 1, all P < .05). BMI, advanced age, FINS, TG and FPG are the risk factors of abnormal ACTH in T2DM patients with gastrointestinal autonomic neuropathy.

Abstract
Gestational diabetes mellitus (GDM) is characterized by a set of metabolic complications arising from adaptive failures to the pregnancy period. Estimates point to a prevalence of 3 to 15% of pregnancies. Its etiology includes intrinsic and extrinsic aspects of the progenitress, which may contribute to the pathophysiogenesis of GDM. Recently, researchers have identified that inflammation, oxidative stress, and the gut microbiota participate in the development of the disease, with potentially harmful effects on the health of the maternal-fetal binomial, in the short and long terms. In this context, alternative therapies were investigated from two perspectives: the modulation of the intestinal microbiota, with probiotics and prebiotics, and the use of natural products with antioxidant and anti-inflammatory properties, which may mitigate the endogenous processes of the GDM, favoring the health of the mother and her offspring, and in a future perspective, alleviating this critical public health problem.

Abstract
BACKGROUND The role of eating habits of pregnant women in the development and treatment of gestational diabetes mellitus (GDM) is well established. OBJECTIVES To estimate the contribution of specific nutrients and dietary patterns in the development or privation of GDM in pregnant women. DATA SOURCES A systematic review of cohort studies, published between January 2019 and January 2020, of English articles using PubMed, Scopus and Europe PMC databases. Search terms included diabetes, pregnancy, dietary, food, and nutrients. STUDY SELECTION Only cohort studies about the association between eating habits before and during pregnancy and the risk of GDM in English were included. The studies used dietary patterns, specific nutrients or records of food intake of the participants using a questionnaire. DATA EXTRACTION Two authors independently extracted data from articles-including dietary patterns, food intake, nutrients, number and demographic data of participants, data about pregnancies-using predefined criteria. RESULTS In total, 28 cohort studies were organised to examine the correlation between dietary patterns and the prevention of GDM. Studies were conducted in 13 countries and included 3 058 242 participants. Of those, 13 (46%) studies focused on the consumption of vitamins, probiotics, micronutrients, folate, vegetables and fruits. Moreover, seven (25%) studies focused on what is considered to be "unhealthy" eating habits, including prudent and Western dietary patterns. The mediterranean pattern was used in three (11%) studies. CONCLUSIONS Ongoing studies support advice to adhere to a healthy balanced diet, with the addition of folic acid and a multi-vitamin suitable for pregnancy. There is new evidence suggesting probiotics and cod-liver oil supplementation may improve glycaemic control and also the important consideration of the psychological influences of eating.

Abstract
Background Dietary supplement use among recreational athletes is common, with the intention of reducing inflammation and improving recovery. We aimed to describe the relationship between omega-3 fatty acid supplement use and inflammation induced by strenuous exercise. Methods C-reactive protein (CRP) concentrations were measured in 1002 healthy recreational athletes before and 24 h after a 91-km bicycle race. The use of omega-3 fatty acid supplements was reported in 856 out of 1002 recreational athletes, and the association between supplement use and the exercise-induced CRP response was assessed. Results Two hundred seventy-four subjects reported regular use of omega-3 fatty acid supplements. One hundred seventy-three of these used cod liver oil (CLO). Regular users of omega-3 fatty acid supplements had significantly lower basal and exercise-induced CRP levels as compared to non-users (n = 348, p < 0.001). Compared to non-users, regular users had a 27% (95% confidence interval (CI): 14–40) reduction in Ln CRP response (unadjusted model, p < 0.001) and 16% (95% CI: 5–28, p = 0.006) reduction after adjusting for age, sex, race duration, body mass index, delta creatine kinase, MET hours per week, resting heart rate and higher education. CLO was the primary driver of this response with a 34% (95% CI: 19–49) reduction (unadjusted model, p < 0.001) compared to non-users. Corresponding numbers in the adjusted model were 24% (95% CI: 11–38, p < 0.001). Conclusion Basal CRP levels were reduced, and the exercise-induced CRP response was attenuated in healthy recreational cyclists who used omega-3 fatty acid supplements regularly. This effect was only present in regular users of CLO. Trial registration NCT02166216, registered June 18, 2014 – Retrospectively registered.

Abstract
Background Gestational diabetes mellitus (GDM) is increasingly common in pregnancy. This study's purpose was to identify the expression of XIST and manifest the potential mechanism of XIST in GDM. Methods Ninety-three patients with GDM and 93 normal pregnant women were included in this investigation. qRT-PCR was conducted to evaluate the expression of miR-497-5p and XIST and the relationship between XIST and fasting blood glucose (FBG) was explored by Pearson assay. The clinical diagnosis of XIST on GDM patients was validated by the receiver operator characteristic (ROC) curve. Cell counting kit-8 (CCK-8) was applied to elucidate cell viability. Luciferase reporter assay was performed to document the relationship among XIST, miR-497-5p, and FOXO1. Results The expression of XIST was increased in GDM patients and HTR-8/SVneo cell models caused by high glucose (HG). The expression of XIST was associated with the FBG levels and appeared to be a feasible indicator in discriminating GDM patients. The expression of miR-497-5p was prominently reduced in GDM patients and cell models. Inhibition of XIST might alleviate the adverse function of HG on cell viability via sponging miR-497-5p. FOXO1 was proved to be a downstream target gene of miR-497-5p. Conclusions Overexpression of XIST and downregulation of miR-497-5p were indicated in this publication. XIST might serve as a promising diagnostic marker for GDM patients. XIST/miR-497-5p/FOXO1 axis played a critical role in the regulation of trophoblast cells.

Abstract
Cod liver oil (CLO) has long been used as medicine or as a functional food. The CLO is a potential source of vitamin D, vitamin A, and omega fatty acids (eicosapentaenoic acid/EPA and docosahexaenoic acid/DHA). Self-nanoemulsifying drug delivery system (SNEDDS) can enhance dissolution, absorption, and bioavailability of hydrophilic and lipophilic substances for oral administration. The objective of this study was to develop a SNEDDS of CLO with good physical characteristics and stability. The optimization formula was carried out using various ratios of oil, surfactant, and cosurfactant. The physical properties of SNEDDS were determined by transmittance percentage, dispersibility, robustness, thermodynamics stability (heating-cooling cycle, centrifugation, and freeze-thaw cycle), and globule size distribution. The optimum formula of CLO-SNEDDS was obtained at a ratio of surfactant and cosurfactant 2 : 1 and a comparison of oil and surfactant mixtures 1 : 6. The CLO-SNEDDS meets the requirement of percent transmittance (97.90±0.85), dispersibility (grade A), and stability based on robustness and thermodynamic stability tests. Diluted SNEDDS has an average globule size of 125 nm with a polydispersity index (PDI) of 0.515. CLO-SNEDDS preparation has good physical characteristics and stability.
