Flaxseed, a rich source of omega-3 polyunsaturated fatty acid alpha-linolenic acid (ALA), lignans, and soluble fiber, has attracted attention for its potential to improve multiple cardiometabolic risk factors. While its benefits are well-recognized, comprehensive evaluations of its direct impact on clinical outcomes, such as the prevention or progression of cardiometabolic diseases, remain limited. Additionally, its potential to support healthy aging and longevity through fundamental biological mechanisms has not been fully elucidated. This review synthesizes existing research on flaxseed supplementation, highlighting its effects on cardiometabolic risk factors and outcomes, the underlying biological mechanisms, and its broader implications for health promotion and aging. Findings demonstrate that flaxseed supplementation significantly improves several cardiometabolic risk factors, including body weight, body mass index, lipid levels, blood pressure, glycemic measures, markers of inflammation (e.g., C-reactive protein and interleukin-6), oxidative stress, and liver enzymes. Blood pressure reductions range from approximately 2 to 15 mmHg for systolic blood pressure and 1 to 7 mmHg for diastolic blood pressure, with the magnitude influenced by dose, duration, and baseline risk profiles. While direct evidence linking flaxseed to the prevention of hypertension, metabolic syndrome, metabolic dysfunction-associated steatotic liver disease, type 2 diabetes, chronic kidney disease, and cardiovascular disease is limited, its bioactive components-ALA, lignans, and fiber-are strongly associated with reduced risks of these conditions. The benefits of flaxseed are mediated through multiple pathways, including anti-inflammatory and antioxidant effects, improved lipid levels, improved glucose metabolism and insulin sensitivity, modulation of gut microbiota, and enhanced vascular health. Beyond cardiometabolic outcomes, flaxseed may influence key biological processes relevant to aging, underscoring its potential to promote healthy aging and longevity. Optimal cardiometabolic benefits appear to be achieved with ground whole flaxseed at doses of ≥ 30 g/day for at least 12 weeks, particularly among individuals at high cardiometabolic risk. Future research should focus on elucidating flaxseed's mechanisms of action, clarifying its role in disease prevention, and refining dietary recommendations to harness its potential for cardiometabolic health and aging interventions., Competing Interests: Declarations.

Background: Plant active substances are extensively utilized in treating rheumatoid arthritis (RA). Despite numerous experimental and clinical studies on plant active substances their efficacy remains largely unsubstantiated. The widespread use of these extracts as therapeutic measures for RA is problematic due to the lack of compelling evidence. Objective: Our research aims to assess the impact of plant active substances on RA by conducting a network meta-analysis. Methods: We systematically searched four electronic databases—PubMed, EMBASE, the Cochrane Central Register of Controlled Trials, and Web of Science—from their inception to August 2024. The main focus was on assessing primary outcomes, including the Visual Analogue Scale (VAS), inflammatory markers, Swollen Joint Count (SJC), Tender Joint Count (TJC), and Disease Activity Score on 28 joints (DAS28). We performed data analysis using StataMP 15.1 software and ranked the therapeutic effects based on the Surface Under the Cumulative Ranking Curve (SUCRA) probability values. Results: Based on screening procedures, 18 eligible studies were incorporated into the analysis. These studies encompassed a total of 1,674 RA patients and investigated 10 different plant active substance therapies. Specifically, 10 studies included VAS indicators, 17 studies included inflammatory marker indicators, 14 studies included DAS28 indicators, 13 studies included SJC indicators, and 13 studies included TJC indicators. Based on SUCRA values, quercetin appeared to be the most effective treatment for decreasing serum VAS levels (67.3%). Furthermore, curcumin emerged as the most promising option for reducing inflammatory marker levels (72.3%), SJC (75.6%), and TJC (76.2%). Lastly, with respect to DAS28, resveratrol emerged as the optimal choice (74.3%). Conclusion: According to the network meta-analysis (NMA), curcumin exhibited superior efficacy compared to placebo in decreasing SJC and TJC. Additionally, curcumin demonstrated greater effectiveness in reducing inflammatory markers. Quercetin was more effective in reducing VAS, and resveratrol was more effective in reducing DAS28. Patients with RA may benefit from these findings. Insightful information from this study is helpful for RA patients to consider using plant active substance therapies. For their efficacy and safety to be confirmed, more proof is needed. [ABSTRACT FROM AUTHOR]

Introduction: Type 2 diabetes is a significant health concern in the 21st century, and its prevalence continues to rise despite efforts to promote preventive lifestyle changes. This increase has led to higher economic burdens, prompting the search for non-pharmacological methods to manage glucose levels. Objective: To assess the effects of flaxseed consumption on biochemical markers (glucose, glycated hemoglobin, total cholesterol, and triglycerides) in adult patients with Type 2 diabetes in Oaxaca, Mexico. Materials and Methods: Participants were recruited and randomized into clinical trials between April and June 2023, and the study protocol was approved by a Human Research Ethics Committee. Results: Consuming 16 g of flaxseed daily for three months led to a significant decrease in glucose, total cholesterol, and triglyceride levels (p < 0.001) in Type 2 diabetes patients in the intervention group (n = 82). Belonging to the control group (n = 84) was correlated with presenting higher levels of glycated hemoglobin (Spearman's Rho 0.640; p < 0.001), higher levels of glucose (Spearman's Rho 0.352; p < 0.001), total cholesterol (Spearman's Rho 0.796; p < 0.001), and triglycerides (Spearman's Rho 0.700; p < 0.001). Conclusions: A daily intake of 16 g of flaxseed is an effective supplementary treatment for adult Mexican patients with Type 2 diabetes, as evidenced by reduced levels of glycated hemoglobin, glucose, cholesterol, and triglycerides in the intervention group. Potential implications for clinical practice: Healthcare providers may consider recommending flaxseed in the diets of patients with obesity, prediabetes, or Type 2 diabetes to improve glucose and lipid metabolism and overall metabolic health.

Background: Enteral feeding uses feeding tubes for liquid food administration. Enteral feeding maintains gastrointestinal function but has complications like aspiration, diarrhea, and constipation. To avoid complications, nurses in intensive care units must have proper knowledge, attitude, and practice towards enteral feeding. Method: A systematic review was conducted. The search was restricted to January 2000 to April 2024, encompassing scientific journals accessible via the following online databases: PubMed (including Medline), Cochrane Library, Scopus, Web of Science, and Embase. Google Scholar was searched comprehensively to include all relevant studies. The search strategy employed the following keywords and medical subject headings: [knowledge OR attitude] AND [enteral feeding OR enteral nutrition] AND nurs*. Only cross-sectional studies were included in this systematic review. Two authors independently conducted the selection of eligible studies, data extraction, and risk of bias assessment. Due to the discrepancies in methodologies and research goals among the investigated studies, a narrative synthesis was conducted. Results: In total, there were 3187 articles found in the initial search across five online electronic databases. Finally, a thorough review was conducted, incorporating 22 studies. Based on the studies analyzed in this systematic review, nurses showed a positive attitude toward enteral feeding; there was a necessity to enhance their knowledge and practice. Continuous education combined with interdisciplinary collaboration can significantly improve nurses' knowledge and practice of enteral feeding. Conclusion: Many studies highlight the necessity of enhancing the knowledge and practice of nurses in this area. Implementing educational interventions has positively impacted nurses' knowledge and performance. [ABSTRACT FROM AUTHOR]

Background and objectives: Chronic kidney disease (CKD) is a progressive illness linked to higher rates of morbidity and death. One of the main causes of CKD is diabetes mellitus (DM), and oxidative stress is essential to the disease's development. It has been demonstrated that the natural antioxidant melatonin reduces inflammation and oxidative damage in renal tissues. Given the lack of robust evidence, this double-blind clinical trial sought to investigate the effects of melatonin supplementation on oxidative stress and inflammatory markers in diabetic CKD patients. Materials and methods: This trial included 41 diabetic patients with CKD (stages 3–4) from Shariati Hospital, Tehran, Iran. For ten weeks, participants were randomized to receive either a placebo or 5 mg of melatonin twice a day. Baseline characteristics, dietary intake, physical activity, and anthropometric measurements were recorded. Oxidative stress (TAC, TOS, MDA) and inflammatory markers (IL-6, hs-CRP) were measured before and after the intervention. Statistical analysis was performed using SPSS, with significance set at p < 0.05. Results: The 10-week trial was completed by 41 participants in total, and no adverse effects were noted. Dietary intake, physical activity, and anthropometric parameters did not significantly differ between the melatonin and control groups in baseline characteristics. Melatonin supplementation decreased oxidative stress and inflammatory biomarkers, including hs-CRP, MDA, TOS, and IL-6. However, these changes were not statistically significant. Conclusion: Our study showed that melatonin supplementation did not significantly affect oxidative stress or inflammatory markers, including TAC, TOS, MDA, IL-6, and hs-CRP, in diabetic patients with CKD. Despite a decrement in TOS, MDA, IL-6, and hs-CRP levels after 10 weeks, this was not statistically significant. Further studies with larger sample sizes, greater dosages, and longer follow-up periods are recommended. [ABSTRACT FROM AUTHOR]

Background: Beta-thalassemia stands as an autosomal recessive disorder that occurs as a result of a defect in the beta-globin chain synthesis of hemoglobin. Oxidative stress has a crucial role in the β-thalassemia pathophysiology. It occurs due to erythroid expansion along with ineffective erythropoiesis. The free hemoglobin oxidation generates reactive oxygen species (ROS), free heme, and iron, thus inducing membrane oxidative damage as well as vascular endothelial dysfunction. Quercetin has a crucial impact on enhancing endothelial dysfunction in thalassemia major. This work aimed to investigate endothelial dysfunction among children diagnosed as beta-thalassemia major by assessing serum level of some endothelial markers (thrombomodulin as well as human ROS) and assessing the quercetin's therapeutic value in improving endothelial dysfunction by measuring the previous markers 12 weeks following therapy. This randomized placebo-controlled study involved 72 children developing transfusion-dependent β-thalassemia major. Their age range fell between 8 and 18 years. They were categorized into two equal groups: group I: received 12 weeks of quercetin therapy and group II: served as control group and received 12 weeks of placebo. Results: Serum ferritin, C-reactive protein, and lactate dehydrogenase levels showed significantly lower values among patients after 12 weeks of quercetin therapy compared with controls. Pre-transfusion hemoglobin was significantly higher in patients after 12 weeks of quercetin therapy in comparison to controls. Frequency of transfusion was significantly less in patients after 12 weeks of quercetin therapy in comparison to controls. Serum levels of ROS and thrombomodulin showed significantly lower values among cases after 12 weeks of quercetin therapy in comparison to controls (p < 0.001). ROS and thrombomodulin respectively carried the sensitivity of 83.33% and 77.78% and specificity of 80.56% and 83.33% in predicting the outcome with cutoff value ≤ 1073 and 232. Conclusions: Twelve weeks of 500-mg quercetin therapy had a potent role in decreasing iron overload and improving frequency of transfusion, oxidative stress ,and endothelial dysfunction in children with β-thalassemia major.

Objective: Metabolic dysfunction-associated steatotic liver disease (MASLD) is a chronic condition affecting a broad population. This review aimed to identify and summarize the current evidence on bioactive-substance-based interventions for adults with MASLD, formerly known as nonalcoholic fatty liver disease (NAFLD), covering publications from 2000 to 2023. Methods: A search was conducted across six databases (MEDLINE, CINAHL, Cochrane CENTRAL, Cochrane Database of Systematic Reviews, Food Science Source, and SPORTDiscus) for randomized controlled trials and other study types (e.g., prospective cohort studies and systematic reviews), reflecting the scoping nature of this review. The search was limited to studies in adults (>18 years old), with an intervention of interest and at least one comparator group. Results: A total of 4572 articles were retrieved, with 201 full-text articles screened for eligibility. Of these, 131 primary studies and 49 systematic reviews were included in the scoping review. The most studied bioactive substances were Curcumin (Turmeric) (n = 25), Silymarin (Milk Thistle) (n = 17), Resveratrol (n = 10), Coffee (n = 7), Green Tea (n = 5), and Berberine (n = 5 each). Moreover, 46 studies reported on 36 other bioactive substances with 2 or fewer articles each. Among the included systematic reviews, 13 focused on Curcumin, 12 on Coffee or Tea, 10 on bioactive substance combinations, 6 on Resveratrol, and 2 each on Silymarin and Artichoke Leaf. The included studies showed substantial heterogeneity in reported outcomes, which primarily focused on hepatic health, body weight, adverse events, glycemic control, blood lipids, and body composition. Conclusions: This scoping review highlights a range of bioactive substances used in the treatment of MASLD. While evidence is abundant for bioactive substances like Curcumin and Silymarin, further research and synthesis of findings is necessary to establish the clinical efficacy of all bioactive substances.

Tryptophan is an essential amino acid that is metabolized in the intestine by gut bacteria into indole derivatives, including tryptamine. However, little is known about which bacterial tryptophan metabolites directly influence obesity. In this study, we identified tryptamine as a bacterial metabolite that significantly reduced fat mass following the intraperitoneal injection of five bacterial tryptophan end-products in a diet-induced obese mouse model. Interestingly, tryptamine, a serotonin analog, inhibited both lipogenesis and lipolysis in adipose tissue, which was further confirmed in a 3T3-L1 adipocyte cell culture study. Moreover, oral tryptamine supplementation markedly reduced fat mass and improved insulin sensitivity in a long-term, high-fat-diet, pair-feeding model. These studies demonstrate the therapeutic potential of tryptamine, a bacterial tryptophan metabolite, in ameliorating obesity and insulin resistance by directly regulating lipogenesis and lipolysis in white adipose tissue.

Pain, a complex symptom encompassing both sensory and emotional dimensions, constitutes a significant global public health issue. Oxidative stress is a pivotal factor in the complex pathophysiology of pain, with glutathione peroxidase 4 (GPX4) recognized as a crucial antioxidant enzyme involved in both antioxidant defense mechanisms and ferroptosis pathways. This review systematically explores GPX4's functions across various pain models, including neuropathic, inflammatory, low back, and cancer-related pain. Specifically, the focus includes GPX4's physiological roles, antioxidant defense mechanisms, regulation of ferroptosis, involvement in signal transduction pathways, and metabolic regulation. By summarizing current research, we highlight the potential of GPX4-targeted therapies in pain management. [ABSTRACT FROM AUTHOR]

Background: The therapeutic properties of Achillea Millefolium (AM) in regulating blood lipids and liver enzymes have been proven in studies. Considering the abnormal lipid levels and elevated liver enzymes in diabetic patients, this study was conducted to investigate the effect of AM on the lipid profile and serum level of liver enzymes in type 2 diabetic (T2D) patients. Methods: In this 90-day double-blind clinical trial study, 60 eligible diabetic patients were enrolled and divided into intervention and control (each 30 patients) groups. The intervention group received AM capsules (dose of 500 mg/day) for 3 months, and the control group received placebo capsules during the same period. Blood was taken from patients on day 0 and day 90. The serum levels of liver enzymes and lipid profiles of patients were measured at baseline and on day 90. The obtained values were analyzed and compared between two control and treatment groups and within each group. Results: AM oral supplementation caused a significant decrease in alanine aminotransferases (ALT; from 28.79 ± 10.99 to 24.41 ± 6.84, p = 0.017) and aspartate aminotransferases (AST; from 24.28 ± 7.91 to 18.76 ± 6.77, p = 0.007). A significant reduction in the levels of serum lipids such as triglyceride (TG; from 161.7 ± 77.18 to 147.3 ± 66.79, p = 0.045), low-density lipoprotein (LDL; from 98.90 ± 35.67 to 80.86 ± 32.10, p = 0.001), and total cholesterol (TC; from 168.3 ± 47.46 to 150.1 ± 38.77, p = 0.006) was noted in AM group. According to these results, after the intervention, the mean of all variables (except HDL) in the two groups had a significant difference (P < 0.05). Conclusion: The study showed that the 3-month treatment of T2D patients with 500 mg/day AM capsules led to the reduction of liver enzymes and the regulation of blood lipids in them.

Aim: To comprehensively investigate the effects of antioxidant nutrients on muscle mass, strength and function in chronic obstructive pulmonary disease (COPD) patients. Methods: PubMed, Embase, Cochrane Library, and Web of Science were comprehensively searched from the inception to January 3, 2024. The quality of randomized controlled trials (RCTs) was measured using the Jadad scale. Weighted mean differences (WMDs) and 95% confidence intervals (CIs) were used as the effect size for measurement data. Further, subgroup analysis was conducted based on whether patients participated in lung rehabilitation plans while receiving nutritional interventions. Sensitivity analysis was performed on all outcomes. Results: A total of 12 studies involving 595 patients with COPD were included, with 11 studies had high quality, and one study had low quality. For muscle mass, patients receiving antioxidant nutrients had a significantly increased lean body mass index compared with those not receiving antioxidant nutrients (pooled WMD: 0.903, 95% CI: 0.264, 1.541, P = 0.006). For patients who did not participate in lung rehabilitation plan while receiving nutritional interventions, antioxidant nutrients brought about a significantly higher lean body mass index (pooled WMD: 1.360, 95% CI: 0.560, 2.160, P = 0.001). For muscle strength, patients in the antioxidant nutrient intervention group had significantly higher hand grip strength (HGS) than those in the non-antioxidant nutrient intervention group (pooled WMD: 1.976, 95% CI: 1.337, 2.615, P < 0.001). Patients receiving antioxidant nutrients had significantly greater inspiratory muscle strength (MIP) than those not receiving antioxidant nutrients (pooled WMD: 8.127, 95% CI: 2.677, 13.577, P = 0.003). Conclusion: Antioxidant nutrient intervention significantly improved HGS, MIP and lean body mass index in COPD. Clinicians should consider increasing food intake or supplementation rich in antioxidants in the treatment plan of patients with COPD. [ABSTRACT FROM AUTHOR]

Background: A common condition that is commonly observed in severely ill individuals is malnutrition. It has been claimed that between 38% and 78% of patients in the intensive care unit are dangerously unwell. Higher rates of morbidity, mortality, and hospital-related costs are associated with these patients. Therefore, this study's objective was to assess the prevalence and risk factors of malnutrition in Zagazig University Hospital's surgical intensive care unit. Methods: This cross-sectional study was conducted in surgical intensive care unit in Zagazig university Hospital on 92 patients admitted to surgical intensive care unit and stayed more than 1 week in surgical intensive care in Zagazig university hospital. Risk factors were assessed in all cases. Results: 92 patients were investigated, 66 of them were nutritionally high risk and the remaining were nutritionally low risk. There is significant increase of nutrition risk in the critically ill score (NUTRIC score), incidence of comorbidities and length of stay in malnourished group. Age ≥ 60 years, comorbidities ≥ 2 and length of stay more than 10 days are considered risk factors of malnutrition. Conclusions: On ICU admission, about 71.8 % of the patients were nutritionally at high risk of malnutrition. Age more than 60 years, presence of more than two comorbidities and prolonged length of stay in ICU more than 10 days are considered risk factors to develop malnutrition in critically ill patients.

The termination of pregnancy is considered an emotionally devastating experience. Early intervention and counseling are essential to prevent adverse complications following pregnancy loss. This study aimed to determine the effect of nursing care based on Swanson's Theory of Caring on women's prenatal grief, depression, anxiety, stress, and coping levels during pregnancy termination. The training and counseling program, based on Swanson's Theory of Caring, included hospital care, a mobile application, and telephone follow-ups. We conducted this prospective randomized controlled experimental study in the gynecology and obstetrics clinic of a tertiary university hospital in Türkiye between September 2021 and May 2022. The study sample consisted of 50 women (intervention group: 25, control group: 25) whose pregnancy was terminated in the second trimester. The women were assigned to groups according to a randomization list created by a statistician. Data collection tools included a Personal Information Form, the Perinatal Grief Scale, the Depression, Anxiety, and Stress Scale, the Coping and Adaptation Process Scale, and the Numerical Rating Scale. We collected the data during hospitalization, between the 6th and 8thweeks after discharge, and at the 12thweek. We performed a chi-square test, a paired samples t-test, and an independent samples t-test on the IBM Statistical Package for the Social Sciences Statistics 26. The intervention group had lower mean perinatal grief (54.76 ± 19.49), depression (2.56 ± 2.39), anxiety (2.08 ± 2.10), and stress (3.52 ± 1.78) scores and higher mean coping and adjustment scores (140.48 ± 11.47) than the control group(p <.05). The intervention group also had a lower perception of labor pain, shorter discharge time, and a higher level of readiness for a new pregnancy (p <.05). The program that we applied in the study was effective in managing the pregnancy termination and post-discharge period in the population we studied. [ABSTRACT FROM AUTHOR]

Purpose: Normal-weight obesity (NWO), characterized by normal body mass index (BMI) but excess body fat, is a potential contributor to chronic diseases. This study aims to assess the relationship between this phenomenon and some metabolic factors in a population of Iranian employees. Design/methodology/approach: This cross-sectional study was conducted on Iranian employees from the baseline data of Employees Health Cohort Study, Shiraz, Iran. Anthropometric measures, including weight, height, waist circumference and percentage of body fat, were obtained from the cohort database. The participants were divided into three groups: healthy, normal-weight obese and overweight/obese. Metabolic variables including blood pressure, fasting blood sugar, lipid profile, liver function enzymes and metabolic syndrome were assessed in relation to the study groups. Findings: A total of 985 participants aged 25–64 years were included. Males with NWO had significantly higher alanine aminotransferase (ALT) levels compared to the healthy group in the fully adjusted model. Also, high-density lipoprotein (HDL) was significantly lower among females with overweight/obesity than healthy group when adjusted for age and energy intake. Furthermore, after adjusting for age and energy intake, both genders in the overweight/obese group showed significantly elevated systolic and diastolic blood pressure, while this was not observed for the NWO group. Lastly, metabolic syndrome was more prevalent in NWO as well as overweight/obesity. Originality/value: These findings further encourage identification of excess body fat, even in normal-weight individuals, to prevent chronic metabolic diseases. Special attention should be paid to subgroups with sedentary occupations, as they may be at increased risk for NWO-related health issues. [ABSTRACT FROM AUTHOR]

Sleep is a fundamental phenomenon that helps maintain normal physiological processes. Conversely, sleep disorders, usually presented as insomnia, are a common public health problem that can lead to multiple pathophysiological changes in humans, including lipid metabolic abnormality. Interestingly, several previous studies have examined the potential relation of insomnia to metabolic syndrome and hyperlipidemia and found that insomnia was associated with elevated plasma cholesterol and triglyceride concentrations. This review summarizes evidence regarding the linkage between insomnia and lipid abnormalities. Moreover, the underlying physiologic mechanisms linking insomnia to lipid abnormalities are systemically discussed. Finally, issues with lipid-lowering drugs and the risk of insomnia are also presented. This knowledge can improve our understanding of the pathophysiological features of insomnia, which may help to prevent and treat insomnia-induced dyslipidemia clinically. [ABSTRACT FROM AUTHOR]

Dysglycemia is a condition preceding diabetes mellitus. The two situations inherent in this condition are called impaired fasting glucose (IFG) and impaired glucose tolerance (IGT). If one of these situations is found in the patient, after the advice of an appropriate diet and physical activity, the addition of nutraceuticals or supplements can be considered, which can stop or delay the progression to diabetes mellitus over time. The purpose was to compile a systematic review about the use of nutraceuticals for treating diabetes and prediabetes and to offer a valuable resource for colleagues working on this crucial subject, thereby improving patient health. The added value of the paper compared to other reviews is that it was written by experts appointed by five different scientific societies dealing with diabetes, nutrition, and complications.

Quercetin, a flavonoid found in vegetables and fruits, has been extensively studied for its health benefits and disease management. Its role in the prevention of various pathogenesis has been well-documented, primarily through its ability to inhibit oxidative stress, inflammation, and enhance the endogenous antioxidant defense mechanisms. Electronic databases such as Google Scholar, Scopus, PubMed, Medline, and Web of Science were searched for information regarding quercetin and its role in various pathogeneses. The included literature comprised experimental studies, randomized controlled trials, and epidemiological studies related to quercetin, while editorials, case analyses, theses, and letters were excluded. It has been reported to have a wide range of health benefits including hepatoprotective, antidiabetic, anti-obesity, neuroprotective, cardioprotective, wound healing, antimicrobial, and immunomodulatory effects, achieved through the modulation of various biological activities. Additionally, numerous in vitro and in vivo studies have shown that quercetin's efficacies in cancer management involve inhibiting cell signaling pathways, such as inflammation, cell cycle, and angiogenesis, activating cell signaling pathways including tumor suppressor genes, and inducing apoptosis. This review aims to provide a comprehensive understanding of the health benefits of quercetin in various pathogeneses. Additionally, this review outlines the sources of quercetin, nanoformulations, and its applications in health management, along with key findings from important clinical trial studies. Limited clinical data regarding quercetin's safety and mechanism of action are available. It is important to conduct more clinical trials to gain a deeper understanding of the disease-preventive potential, mechanisms of action, safety, and optimal therapeutic dosages. Furthermore, more research based on nanoformulations should be performed to minimize/overcome the hindrance associated with bioavailability, rapid degradation, and toxicity. [ABSTRACT FROM AUTHOR]

Fruits are excellent sources of substrate for various fermented products, including fruit vinegars, which are typically produced by submerged fermentation. Some evidence suggests that fruit vinegar consumption can alleviate certain disorders, including hyperlipidemia, inflammation, and hyperglycemia. Fruit vinegars also have bacteriostatic and antihypertensive actions. Recent studies also suggest that apple vinegar may offer benefits in treating insulin resistance, osteoporosis, and certain neurological diseases such as Alzheimer's disease; it may also support weight loss. Recent studies in animal and human models have considerably broadened our understanding of the biological properties of not only fruit vinegars but also oxymels, i.e., mixtures of vinegar and honey or sugar. This paper reviews the current state of knowledge regarding vinegars and oxymels, with a special emphasis on their chemical composition and the mechanisms behind their biological activity and pro-health potential. The multidirectional effects of fruit vinegars and oxymels result from the synergy of different chemical compounds, including organic acids (mainly acetic acid), phenolic compounds, vitamins, minerals, and fermentation products. However, more studies are needed to understand the interactions between all the different components, not only the phenolic compounds and organic acids. In addition, more research is needed on their mechanisms of action. Although no serious side effects have been noted to date, further studies with large sample sizes are needed to understand the possible side effects of long-term fruit vinegar and oxymel use.

Pomegranate (Punica granatum) is a widely cultivated fruit historically recognized for its health benefits and is regarded as a nutritional powerhouse. Pomegranate has a unique composition of bioactive compounds including hydrolysable tannins, anthocyanins, and other polyphenolic components. Of those, punicalagin and its subsequent metabolites are the most extensively studied, demonstrating antioxidant, anti-inflammatory, anti-cancer, and anti-nociceptive activity. The compounds possess promising therapeutic potential for many diseases, including conditions affecting the female reproductive system. This scoping review examines the pharmacodynamics of pomegranate's bioactive compounds and synthesizes the current literature concerning the role in benign gynecological disorders. Pomegranate extract decreased testosterone levels, levels of oxidative stress and inflammation biomarkers in women with polycystic ovary syndrome, erstwhile favorably impacting some cardiovascular risk factors in women. Pomegranate supplementation improved menopause specific health-related quality of life in women. In a pre-clinical murine model following ovariectomy, improved bone formation and reduced vaginal atrophy were associated with pomegranate treatment. Existing data suggests that additional research on the beneficial antioxidant, anti-inflammatory, anti-proliferative, and anti-nociceptive effects of pomegranate extracts for benign gynecologic conditions is warranted., Competing Interests: Declarations.

Objectives: Altered appetite-related gut hormone concentrations may reflect a physiological adaptation facilitating weight regain after weight loss. This review investigates hormonal changes after weight loss achieved through calorie restriction (CR), exercise (EX), or both combined (CREX)., Methods: A systematic search of PubMed (MEDLINE), EMBASE, SPORTDiscus, Cochrane Library, Web of Science, and ClinicalTrials.gov was conducted to identify randomised controlled trials (RCTs) and non-RCTs reporting in a fasting state either pre- and post-intervention appetite-related hormone concentrations or the changes therein after weight loss. The hormones examined were ghrelin, peptide tyrosine tyrosine (PYY), glucagon-like peptide -1 (GLP-1), and cholecystokinin (CCK), in their total and/or active form. Standardised mean differences (SMD) were extracted as the effect size., Results: 127 studies were identified: 19 RCTs, 108 non-RCTs, 1305 and 4725 participants, respectively. In response to weight loss induced by CR, EX or CREX, the meta-analysis revealed an increase in total ghrelin from both RCTs (SMD: 0.55, 95% CI: 0.07-1.04) and non-RCTs (SMD: 0.24, 95% CI: 0.14-0.35). A decrease in acylated ghrelin was identified for RCTs (SMD: -0.58, 95% CI: -1.09 to -0.06) but an increase was observed for non-RCTs (SMD: 0.15, 95% CI: 0.03 to 0.27). Findings also revealed a decrease in PYY (total PYY: SMD: -0.17, 95%CI: -0.28 to -0.06; PYY 3-36 : SMD: -0.17, 95%CI: -0.32 to -0.02) and active GLP-1 (SMD: -0.16, 95% CI: -0.28 to -0.05) from non-RCTs. Changes in hormones did not differ among the three interventions when controlling for weight loss. Meta-regression indicated that greater weight loss was associated with a greater increase in total ghrelin., Conclusions: Weight loss induced by CR, EX, or CREX elicits an increase in total ghrelin, but varied responses in other appetite-related hormones. The extent of weight loss influences changes in appetite-related gut hormone concentrations., Competing Interests: Competing interests: The authors declare no competing interests., (© 2025.

Purpose: Hemodialysis (HD) patients commonly experience enhanced oxidative stress and inflammation, potentially increasing the risk of malnutrition. Selenium levels are typically lower in HD individuals. Selenium deficiency has been identified as a risk factor for oxidative stress and inflammatory responses. Therefore, we intended to perform a meta-analysis to assess the impact of selenium supplementation on HD patients., Methods: PubMed, Embase, Cochrane Library, and Web of Science were searched for randomized controlled trials (RCTs) on the effect of selenium supplementation on HD patients until September 31, 2024. The data analysis was conducted using Stata15.0 software., Results: Seven RCTs, with 2080 participants, were finally included, with 1029 in the selenium group and 1051 in the control group. The meta-analysis unraveled no statistically significant impact of selenium supplementation on body mass index (SMD = 0.15, 95% CI (- 0.20, 0.49), triglyceride [(SMD = - 0.02, 95% CI (- 0.44, 0.41)], total cholesterol [(SMD = - 0.18, 95%CI (- 0.41, 0.05)], low-density lipoprotein [(SMD = - 0.37, 95% CI (- 1.04, 0.31)], high-density lipoprotein cholesterol [(SMD = 0.15, 95% CI (- 0.54, 0.84)], C-reactive protein [(SMD = - 0.10, 95% CI (- 0.46, 0.27)], ferritin [(SMD = - 0.02, 95% CI (- 0.29, 0.26)], Hx-C reactive protein [(SMD = 0.00, 95% CI (- 1.02, 1.03)], and hemoglobin [(SMD = 0.01, 95% CI (- 0.57,0.59)]. Only selenium levels were significantly increased after selenium supplementation [SMD = 2.83, 95% CI (2.43, 3.24)]., Conclusion: Selenium supplementation can increase selenium levels in HD patients, without notable impacts on weight, triglycerides, and total cholesterol., Competing Interests: Declarations.

Cardiovascular diseases (CVDs) are the leading causes of death and illness worldwide. While there have been advancements in the treatment of CVDs using medication and medical procedures, these conventional methods have limited effectiveness in halting the progression of heart diseases to complete heart failure. However, in recent years, the hormone melatonin has shown promise as a protective agent for the heart. Melatonin, which is secreted by the pineal gland and regulates our sleep-wake cycle, plays a role in various biological processes including oxidative stress, mitochondrial function, and cell death. The Sirtuin (Sirt) family of proteins has gained attention for their involvement in many cellular functions related to heart health. It has been well established that melatonin activates the Sirt signaling pathways, leading to several beneficial effects on the heart. These include preserving mitochondrial function, reducing oxidative stress, decreasing inflammation, preventing cell death, and regulating autophagy in cardiac cells. Therefore, melatonin could play crucial roles in ameliorating various cardiovascular pathologies, such as sepsis, drug toxicity-induced myocardial injury, myocardial ischemia-reperfusion injury, hypertension, heart failure, and diabetic cardiomyopathy. These effects may be partly attributed to the modulation of different Sirt family members by melatonin. This review summarizes the existing body of literature highlighting the cardioprotective effects of melatonin, specifically the ones including modulation of Sirt signaling pathways. Also, we discuss the potential use of melatonin-Sirt interactions as a forthcoming therapeutic target for managing and preventing CVDs., Competing Interests: Declarations.

Background: Impacts of milk proteins (MPs) on inflammation are uncertain. The current systematic review and dose-response meta-analysis of randomized controlled trials (RCTs) evaluated the effects of whey protein (WP), casein protein (CP), or MP supplementation on serum levels of cytokines and adipokines in adults., Methods: A comprehensive search of various online databases was conducted to find appropriate clinical trials published until September 2024. A random-effect statistical model was implemented., Results: The meta-analysis included 53 RCTs. It was indicated that MP supplements had no substantial effects on serum values of C-reactive protein (CRP), tumor necrosis factor-alpha (TNF-α), adiponectin, and leptin. However, there were statistically significant decreases in serum levels of interleukin-6 (IL-6) following supplementation with MP (weighted mean difference (WMD): - 0.25 pg/mL, 95% CI - 0.48, - 0.03; P = 0.026) in the intervention group compared with the control group., Conclusion: This study revealed that MP supplementation may not have any considerable impacts on the levels of cytokines and adipokines., Competing Interests: Declarations.
