Association of Metabolic Syndrome or Weather Conditions with the Severity and Prognosis of Sudden Sensorineural Hearing Loss.

It is reported that sudden sensorineural hearing loss (SSNHL) is closely related to diabetes, hypertension, and hyperlipidemia. While the metabolic syndrome (MetS) is a multifactorial disease that includes diabetes, hypertension, dyslipidemia, and obesity, which are known to be associated with SSNHL. Weather conditions have long been known to affect the SSNHL. This study aimed to make a clear connection between MetS, or weather conditions, and the severity and prognosis of SSNHL. 127 SSNHL patients have been divided into the MetS group and the non-MetS group, and the demographic and clinical characteristics of the 2 groups have been analyzed retrospectively. There were 52 (40.9%) patients in the MetS group, while there were 75 (59.1%) patients in the non-MetS group. The rate of vertigo, hypertension, diabetes, lower high-density lipoprotein cholesterol (HDL-C) levels, high triglyceride (TG), and body mass index (BMI) ≥25 (kg/m2 ) were significantly higher in the MetS group than those in non-MetS group. Vertigo, hypertension, and Mets were linked to the severity of hearing loss. The rate of complete recovery and partial recovery in the MetS group was clearly lower than that in non-MetS group. According to the multivariate analysis, MetS was significantly associated with a poorer prognosis of SSNHL; a high ambient temperature difference at onset and hypertension were correlated with a poor prognosis. These results demonstrate that the severity and prognosis of SSNHL can be influenced by the MetS. High ambient temperature differences at onset and hypertension were indicators of a poor prognosis for SSNHL.

Liver Biopsy Technique for Analysis of Hepatic Content during Pregnancy and Early Lactation in Dairy Goats.

Biopsy techniques in dairy goats are currently limited. This study aimed to describe a liver biopsy technique in dairy goats and to evaluate liver triglyceride levels and glycogen content. Sixty-nine dairy goats in the final stage of pregnancy and early lactation period were selected. Fifty goats were selected randomly for hepatic biopsy (HB) according to gestational period and were characterized according to fetus number (single: n = 16, multiple: n = 34), supplementation with propylene glycol (diet: n = 23, diet+PG: n = 27), and milk production levels (high: 3.0 ± 0.4 L/day, n = 15; low: 1.4 ± 0.4 L/day, n = 26). Liver tissue samples were obtained through biopsy on days -30, -20, -15, -10, -5, and 15 days after calving. Hepatic triglyceride and glycogen were quantified. The results were analyzed using the F-test at a 5% significance level and a comparison of means using the Tukey test. The liver biopsies did not influence dry matter intake, body weight, or milk yield. Hepatic glycogen concentration was lower 15 days after calving than it was prior to calving, except on day -20. Goats that generated high levels of milk production had lower triglyceride levels than goats that generated low levels of milk production. The biopsy technique is a safe method for obtaining tissue and evaluating liver content in dairy goats. The milk production level and days relative to parturition influence the hepatic triglyceride and glycogen content in dairy goats.

Myosteatosis predicts bariatric surgery response: A longitudinal study in patients with morbid obesity.

Data on the preoperative factors for bariatric surgery response in patients with morbid obesity are limited, and there are no studies on the relationship between myosteatosis and surgery response. We investigated the preoperative factors determining bariatric surgery response and the impact of preoperative muscle fat infiltration on bariatric surgery response. This retrospective longitudinal cohort study included 125 individuals (37 men, 88 women) with morbid obesity who underwent bariatric surgery. Muscle fat infiltration (skeletal muscle fat index [SMFI]) was evaluated using computed tomography-based psoas muscle mass and density at the 4th lumbar level. A bariatric surgery response was defined as ≥50% excessive weight loss at one year postoperatively. Before bariatric surgery, the patient mean body weight and body mass index (BMI) were 107.0 kg and 39.0 kg/m2, respectively. After one year, the mean body weight was 79.6 kg. The mean excessive weight loss at one year was 75.6% and 102 (81.6%) patients were categorized as responders. There were no statistically significant differences in initial BMI, age, sex, or proportion of diabetes between responders and non-responders. Responders were more likely to have lower SMFI and triglyceride and glycated hemoglobin A1c levels than non-responders at baseline (P<0.05). Multiple logistic regression analysis showed that a lower baseline SMFI was associated with bariatric surgery response (odds ratio=0.31, 95% confidence interval=0.14-0.69, P=0.004). Preoperative myosteatosis may determine the response to bariatric surgery.

Metformin versus Metformin Plus Statin Effect on Lipid Profile in Type 2 Diabetic Patients

Metformin is commonly used drug for type 2 diabetes and may also impact lipid profiles. Statins are often combined with metformin to manage dyslipidemia, but their comparative efficacy on lipid profiles is not well established. This study aimed to compares the effects of metformin alone versus metformin with statins on lipid profiles and to investigate the impact of different metformin doses on these profiles. A cross-sectional study was conducted at Aljabal Alakdar Diabetic Clinic in East Libya from July to December 2023, involving 200 adults with type 2 diabetes. Participants were divided into Group A (metformin only) and Group B (metformin plus statin). Inclusion criteria were adults aged 18-75 years, on metformin for at least 3 months, with recent lipid profile data, and who provided informed consent. Exclusion criteria were additional lipid-lowering drugs or any medications known to affect lipid profiles, type 1 diabetes, severe comorbidities, and pregnancy. Data were analyzed using SPSS version 27 with MANOVA, and significance was set at p &lt; 0.005. The mean age was 58.62 years, mean diabetes duration was 11.43 years, with 47.5% males and 52.5% females. Mean HbA1c was 7.98%, mean urea was 36.5 mg/dL, and mean creatinine was 0.95 mg/dL. Lipid profile parameters included mean LDL cholesterol at 89.09 mg/dL, HDL cholesterol at 47.71 mg/dL, total cholesterol at 175.6 mg/dL, and triglycerides at 169.4 mg/dL. The key lipid parameters showed a significant difference (p &lt; 0.000) between groups, with the metformin-only group exhibiting lower LDL, HDL, triglycerides, and total cholesterol compared to the metformin plus statin group. Our study found that metformin alone achieved better lipid control than metformin combined with statins, with a 1g dose showing notable antihyperlipidemic effects.

Influence of maternal α-lipoic acid supplementation in Sprague Dawley rats on maternal and fetal metabolic health in pregnancies complicated by obesity

The objective of this study was to investigate the influence of α-lipoic acid (LA; R enantiomer) supplementation on maternal and fetal metabolic health in pregnancies complicated by maternal obesity. Forty female Sprague-Dawley rats were randomized to one of 4 treatment groups (n=10/group) throughout prepregnancy (3 weeks) and gestation (20 days): (1) a low calorie control (CON); (2) a high calorie obesity-inducing diet (HC); (3) the HC diet with 0.25% LA (HC+LA) or; (4) the HC diet pair-fed to match the caloric intake of the HC+LA group (HC+PF). On gestation day 20, pregnant rats were placed under anesthesia for collection of maternal/fetal blood and tissues. Compared with the HC group, LA-supplemented mothers demonstrated lower maternal prepregnancy and gestational weight gain (GWG), improved glycemic control (lower homeostatic model assessment for insulin resistance), and higher cholesterol concentrations in serum [high-density lipoprotein cholesterol (HDL-C) and low-and very-low density lipoprotein cholesterol (LDL/VLDL) fractions] and liver. Male and female fetuses from LA-supplemented mothers exhibited lower body weight, improved insulin sensitivity, and evidence of altered lipid metabolism including lower serum HDL-C, lower serum triglyceride (TG), and increased hepatic TG accumulation. Although maternal LA supplementation showed some benefit for both mothers and fetuses with respect to obesity and glycemic control, concern about the potential longer-term implications of liver cholesterol (mothers) and TG accumulation (fetuses) needs further investigation.

Short-Term Atorvastatin Therapy in Healthy Individuals Results in Unaltered Plasma MMP Levels and Disrupted MMP-7 Correlation with Blood Lipids and Blood Count-Derived Inflammatory Markers.

Background: Matrix metalloproteinases (MMPs) play an important role in the pathophysiology of atherosclerosis. Reportedly, statins can decrease MMP activity in patients with atherosclerotic cardiovascular disease, but this effect has not been studied in healthy individuals. Methods: MMPs 2, 7, and 9 and several other parameters were measured before and after a four-week course of moderate-dose atorvastatin (20 mg/day) in 21 healthy individuals. Results: Atorvastatin treatment resulted in lower total cholesterol, LDL-cholesterol, non-HDL-cholesterol, and triglycerides (p < 0.001 for all), but higher levels of plasma enzymes AST, ALT, CK, and LDH (p < 0.05 for all). No effect of atorvastatin on plasma MMP median concentrations was recorded. Before treatment, moderate positive significant correlations were found between MMP-7 and age, blood lipids, and blood count-derived inflammatory markers. Pre-treatment MMP-7 was best predicted by the total cholesterol-to-HDL cholesterol ratio in a remnant cholesterol-weighted least squares regression model. After atorvastatin treatment, MMP-7 no longer correlated with these markers. Conclusions: While the effect of statins on plasma MMPs in atherosclerosis is controversial, short-term moderate-dose atorvastatin treatment does not seem to affect levels of MMPs 2, 7, and 9 in healthy individuals. However, an intriguing correlation between MMP-7 and atherosclerosis-related blood lipids and neutrophil-associated inflammatory biomarkers seems to be disrupted by atorvastatin independently of hsCRP, possibly via pleiotropic effects.

Seed Disinfection Treatments Minimized Microbial Load and Enhanced Nutritional Properties of Fenugreek Sprouts Which Alleviated Diabetes-Negative Disorders in Diabetic Rats.

Sprouts are an attractive food product that contains high amounts of nutritional substances and has pro-health features. Sprout consumption has strongly increased despite its potential risk to health due to its microbial load. Both the safety and shelf life of sprouts may be negatively affected by a high microbial load. To reduce the microbial contamination in sprouts before consumption, the initial microbial load on the seeds needs to be controlled. Many herbal sprouts have been recommended for diabetes, and fenugreek is one of these sprouts. Thus, the current experiment aimed at disinfecting fenugreek seeds using microwave (5, 10, and 20 s) and hot water (30, 45, and 60 s) treatments for different durations. The best-disinfected sprouts with the highest nutritional properties were used to evaluate their influence on streptozocin-induced diabetic rats in comparison with fenugreek seed feeding. Microwave treatments showed the highest sprout length, fresh weight, total free amino acids, antioxidants, reducing sugars, and total phenols. Additionally, microwave seed treatments showed the lowest bacteria and mold counts on sprouts produced relative to hot water treatments, and the best seed treatment was a microwave for 20 s, which gave the best values in this respect. Feeding diabetic rats with different fenugreek seeds or sprout rates (0, 5, 7.5, and 10% w/w) improved body weight, restricted the growth of glucose levels, lowered total cholesterol and triglycerides, and improved HDL compared with the positive control group, and fenugreek sprouts at higher rates showed the maximum improvements in blood glucose, total cholesterol, and triglycerides. Treating fenugreek seed with microwave radiation for 20 s to disinfect the seeds before sprouting is recommended for lowering the microbial load with optimum nutritional and antioxidant activity, and feeding diabetic rats with these sprouts at the rate of 7.5 and 10% had promising effects on hyperglycemia and associated disorders.

Characteristics of sialolithiasis in Israel, a big-data retrospective study of 5100 cases.

The aim of this study was to identify risk factors for sialolithiasis patients using a large community and hospital-based cohort. A retrospective case-control study was conducted on 20,396 individuals, including 5100 sialolithiasis patients and 15,296 matched controls. Demographics and laboratory data were obtained from electronic medical records. Statistical analyses were performed to identify significant differences between the two groups. A p-value of <0.05 was considered significant. Sialolithiasis was more prevalent in women, with a mean age at diagnosis of 55.75 years. Several geographic location variables emerged as risk factors for sialolithiasis including Israeli birth, higher socioeconomic communities, and specific areas of residency. Tobacco smoking (odds ratio = 1.46) was a significant risk factor. Low high-density lipoprotein levels, elevated triglycerides, and elevated amylase levels were associated with sialolithiasis. This study provides valuable insights into the demographic and laboratory characteristics of sialolithiasis patients, indicating that area of residency and lifestyle factors contribute to the risk of developing sialolithiasis. The findings may contribute to a better understanding of the disease and the development of preventative measures or early diagnostics tools.

Association between coffee consumption and metabolic syndrome in Korean adults.

Studies examining the association between coffee consumption and metabolic syndrome (MetS), considering different coffee types, have reported inconsistent results. We investigated the relationship between coffee consumption and MetS, taking into account coffee types, using data from the Korea National Health and Nutrition Examination Survey conducted from 2016 to 2021 among 14,631 adults aged 19-64 years. We used a 24-h dietary recall method to assess diet, including the type and quantity of coffee consumed. Coffee was categorized into black coffee and coffee with sugar and/or cream (non-drinkers, ≤1, 2-3, and >3 cups/day). Multivariable logistic regression models were utilized to investigate the relationship between coffee consumption and MetS, defined by the harmonized criteria. After adjusting for potential covariates, for women, 2-3 cups/day of black coffee were inversely associated with MetS (OR = 0.66; 95% CI = 0.46-0.96). Three or fewer cups per day of black coffee were inversely associated with low high-density lipoprotein cholesterol (HDL-C) and elevated triglycerides in women. Coffee consumption was not significantly associated with MetS in men. Consumption of coffee with sugar and/or cream or more than three cups per day of coffee was not significantly associated with MetS overall. Our findings suggest that moderate of 2-3 cups/day of black coffee consumption is inversely associated with MetS in women, possibly due to its favorable impact on HDL-C and triglycerides. Further prospective studies examining the consumption of different coffee types in relation to MetS are warranted to offer definitive evidence.

Cross-sectional and Mendelian randomization study of fibroblast growth factor 19 reveals causal associations with metabolic diseases.

Fibroblast growth factor 19 (FGF19) is an intestinal-derived factor that plays a role in metabolic diseases. We performed a differential study of circulating FGF19 levels and investigated the causal effects of FGF19 on metabolic diseases using Mendelian randomization (MR). Firstly, 958 subjects were included in the physical examination center of affiliated hospital from January 2019 to January 2021. Dividing the subjects into different subgroups to compare FGF19 levels. We conducted a two-sample MR analysis of genetically predicted circulating FGF19 in relation to alcohol, cardiovascular and metabolic biomarkers and diseases, and liver function biomarkers using publicly available genome-wide association study summary statistics data. The circulating FGF19 levels in nonalcoholic fatty liver disease (NAFLD) patients were lower than those without NAFLD (P<0.001). The FGF19 levels in participants with obese were lower than those without obese (P<0.001). In two-sample MR analyses, genetically predicted higher circulating FGF19 levels was significantly associated with lower aspartate aminotransferase, γ-glutamyltransferase, triglycerides, total cholesterol, low-density lipoprotein, and C-reactive protein concentrations (P<0.05) and a negative correlation with cardiovascular disease and cirrhosis whereas a positive association with type 2 diabetes mellitus (P<0.05). Our study found that circulating FGF19 levels were lower in NAFLD and obese populations. Additionally, our MR research results support the causal effects of FGF19 on improved liver function, lipids, and reduced the occurrence of inflammation, cardiovascular disease, and cirrhosis. We found a positive correlation with diabetes, which may indicate a compensatory increase in regulating above FGF19 resistance states in humans.

Validation of the Global Leadership Initiative on Malnutrition Criteria for Predicting Adverse Outcomes in Acute Pancreatitis.

The Global Leadership Initiative on Malnutrition (GLIM) has proposed criteria for the diagnosis of malnutrition. No studies validated the GLIM criteria in acute pancreatitis (AP). The present study aimed to validate the predictive capacity of GLIM criteria for adverse outcomes in AP patients. Clinical data of 269 patients with AP were analyzed retrospectively. The Nutritional Risk Screening 2002 (NRS2002) was chosen as the screening tool. Multivariate logistic regression analyses evaluated the adverse clinical outcomes in malnourished patients. Overall, 160 patients (59.5%) were at nutritional risk and 38 (14.1%) were malnourished. Reduced muscle mass/ low bodymassindex + inflammation combinations contributed most to malnutrition overall and in each subgroup. The malnourished group had lower hemoglobin, neutrophils, albumin, total cholesterol, and triglycerides than the well-nourished group. The malnourished group had higher hospitalization costs (CNY, 11319.34 vs 9258.22, p <0.001) and more local complications (34.2% vs 14.7%, p =0.009) than the well-nourished group. There was an interaction between malnutrition and overweight/obesity on local complications (p for interaction = 0.023). Multivariate logistic regression showed malnutrition was significantly associated with local complications (OR 12.2, 95% CI: 2.51-59.37), infectious complications (OR 9.95, 95% CI: 1.25-79.44) and composite adverse outcome (OR 4.78, 95% CI: 1.05-21.73) in the overweight/obesity subgroup. There was no association between malnutrition and the rate of various adverse outcomes in the non-overweight/obesity subgroup. Additionally, we observed an association between malnutrition and composite adverse outcome (OR 6.75, 95% CI: 1.49-30.68) in patients <70 years only in females. Malnourished AP patients were more likely to have adverse outcomes than well-nourished patients. Malnutrition was associated with various adverse outcomes only in the overweight/obesity subgroups.

Association of Beverage Consumption with Cardio-metabolic Risk Factors and Alanine Transaminase Levels in Children and Adolescents: The CASPIAN-V Study.

This study aims to evaluate the association of beverage consumption with cardiometabolic risk factors and alanine transaminase (ALT) levels in children and adolescents. This nationwide study is a part of the fifth survey of a national surveillance program in Iran. Overall, 4200 students, aged 7-18 years, were selected from 30 provinces by multi-stage cluster sampling. In addition to filling in questionnaires, blood sampling and biochemical tests were done. The weekly use of six different beverage types including milk, juice, tea, coffee, soda, and non-alcoholic beer, was documented by interview. The participation rate was 91.5% (n = 3843), and data of 3733 students were complete for the current study. Beverages containing high levels of sugar such as soda and non-alcoholic beer were significantly associated with higher levels of ALT. Model coefficient of regression (SD) was 0.66 (0.31) (P value: 0.034). Healthy beverages such as milk and fresh juice and also beverages containing high levels of caffeine did not have significant association with ALT levels (P value = 0.32, P value = 0.60). Healthy beverages had a significant and inverse relationship with triglycerides (TG) (P value = 0.029), total cholesterol (TC) (P value = 0.008) and low-density lipoprotein (LDL) (P value = 0.008) levels. This study showed that consuming sugar-sweetened beverages is significantly associated with higher levels of ALT, whereas healthy beverages are associated with a better cardiometabolic profile meaning that consuming healthy beverages leads to lower TG, TC, and LDL levels. The effects of beverages on children's health should be emphasized in health recommendations.

Coffee pulp improves glucose and lipid metabolism disorder in high-fat diet-induced diabetic mice

BackgroundCoffee berry extracts are anti-lipogenic and lipolytic. This study aims to investigate the effect and mechanism of coffee pulp on high-fat diet (HFD)-induced glucose and lipid metabolism disorder in mice. MethodsThe type 2 diabetes (T2D) mouse model was established by feeding the C57BL/6 J mice with HFD. Mice were administered with coffee pulp diluted in drinking water before or after the establishment of the T2D mouse model. After treatment, the body weight and fasting blood glucose (FBG) of mice were monitored; the intraperitoneal glucose tolerance test (IPGTT) of mice was performed; plasma insulin was determined by ELISA; serum total cholesterol (TC), triglyceride (TG) and liver TG were determined by biochemical analysis; hematoxylin-eosin (H&E) staining was used to evaluate organ histomorphology. Gene expression of key genes in de novo lipogenesis (DNL) in the liver was examined by quantitative reverse transcription PCR (RT-qPCR). ResultsMice that consumed coffee pulp after modeling showed reduced FBG and liver TG, improved IPGTT, and alleviated fatty liver. Consuming coffee pulp before modeling prevented HFD-induced blood glucose and plasma TG increases. Mice consuming coffee pulp also had lower body fat and liver TG compared to the model group. qPCR results showed that the expression of transcription factors (Srebp1, PPARγ) and genes (Fasn, CideA, Plin3, Plin4, Plin5) related to DNL and lipid droplets (LD) formation in the liver of mice consuming coffee pulp were significantly lower than those of the control group. ConclusionsOur study demonstrated that coffee pulp can attenuate HFD-induced disorders of glucose and lipid metabolism, and this effect may be related to the key pathways of lipid synthesis DNL and LD formation pathways in the liver.

Lipidomics and metabolomics investigation into the effect of DAG dietary intervention on hyperuricemia in athletes

The occurrence of hyperuricemia (HUA; elevated serum uric acid) in athletes is relatively high despite that exercise can potentially reduce the risk of developing this condition. Although recent studies have shown the beneficial properties of DAG in improving overall metabolic profiles, a comprehensive understanding of the effect of DAG in modulating HUA in athletes is still lacking. In this study, we leveraged combinatorial lipidomics and metabolomics to investigate the effect of replacing TAG with DAG in the diet of athletes with HUA. A total of 1,074 lipids and metabolites from 94 classes were quantitated in serum from 33 athletes, who were categorized into responders and non-responders based on whether serum uric acid levels returned to healthy levels after the DAG diet intervention. Lipidomics and metabolomics analyses revealed lower levels of xanthine and uric acid in responders, accompanied by elevated plasmalogen phosphatidylcholines and diminished acylcarnitine levels. Our results highlighted the mechanisms behind how the DAG diet circumvented the risk and effects associated with high uric acid via lowered triglycerides at baseline influencing the absorption of DAG resulting in a decline in ROS and uric acid production, increased phospholipid levels associated with reduced p-Cresol metabolism potentially impacting on intestinal excretion of uric acid as well as improved ammonia recycling contributing to decreased serum uric acid levels in responders. These observed alterations might be suggestive that successful implementation of the DAG diet can potentially minimize the likelihood of a potentially vicious cycle occurring in high uric acid, elevated ROS, and impaired mitochondrial metabolism environment.

Association between vitamin D deficiency and serum lipid levels in a group of Romanian patients.

Vitamin D deficiency is widespread across the globe. Numerous reports have linked vitamin D deficiency to certain non-skeletal diseases such as cardiovascular diseases. According to recent studies, there is evidence indicating a possible link between 25-hydroxyvitamin D deficiency and dyslipidemia. The main aim of this study is to investigate the relationship between vitamin D levels and lipid profile and to identify people who may benefit from vitamin D supplementation. In this observational study, a total of 154 patients were included, 98 women and 56 men, aged between 19 and 82 years, in which serum vitamin D levels, total cholesterol, high density lipoprotein cholesterol (HDL-C), low density lipoprotein cholesterol (LDL-C), triglycerides (TG) and blood sugar were analyzed. The serum levels of vitamin D showed some differences, being lower in patients with dyslipidemia, with a positive correlation between vitamin D levels and total cholesterol (F ratio = 7.3247, p=0.008), and also with LDL cholesterol (F ratio = 5.0023, p=0.027). The HDL-C fraction and triglycerides showed no significant correlation with the serum levels of vitamin D. Further on, we divided the patients according to the fraction that had pathological values and compared the levels of vitamin D between these categories. We observed that the lowest levels of vitamin D were present in patients with all lipid parameters modified (HIGH-TC/LOW-HDL/HIGH-LDL/HIGH-TG), and also the highest levels of low HDL-C and high LDL-C. Our research provides additional evidence to the unfavorable lipid profile found in people with vitamin D deficiency.

The prevalence of metabolic syndrome in primary aldosteronism and essential hypertension: A systematic review and meta-analysis.

It remained debates on metabolic-related disorders in patients with primary aldosteronism (PA) and essential hypertension (EH). A systematic review and meta-analysis was conducted to explore the prevalence of metabolic syndrome (MS) and the related indicators in PA and EH. PubMed, Embase, Web of Science and the Cochrane Central Register of Controlled Trials from their commencement to December 2023 were searched for eligible studies. The meta-analysis was performed by Review Manager 5.3 and STATA 15.1 software. A total of 12 studies were included, revealing that there was no significant difference between PA and EH in the prevalence of MS (1.27[0.92, 1.76], p=0.14) with higher heterogeneity (I2=68%, p=0.0002), while it became significant different (1.45[1.17, 1.81], p=0.0008) and lower heterogeneity (I2=26%, p=0.19) in patients who were overweight or obese by subgroup analysis. Higher systolic blood pressure (2.99[0.67, 5.31], p=0.01; I2=43%, p=0.06) and diastolic blood pressure (2.10[0.82, 3.38], p=0.001; I2=36%, p=0.11) with lower heterogeneity, and lower triglyceride in PA group with higher heterogeneity (-0.23[-0.37, -0.09], p=0.001; I2=76%, p<0.0001) were observed. No significant difference was found in other indicators. This study showed a higher prevalence of MS in patients who were overweight or obese with PA. However, it was not the same in these patients who were in normal weight. More researches were needed to explore the relationship between PA and metabolism of glucose and lipid.

Causal association between triglycerides and cholesterol-lowering medication with non-rheumatic valve disease: A 2-sample Mendelian randomization study.

Previous studies have found a possible causal relationship between triglycerides and lipid-lowering drugs and valvular disease. The aim of this study was to explore the potential causal relationship between triglycerides and lipid-lowering drugs and valvular disease using Mendelian randomization (MR) analysis. Data sets associated with triglycerides (441,016 participants and 12,321,875 single nucleotide polymorphisms [SNPs]) and cholesterol-lowering drugs (209,638 participants and 9851,867 SNPs) were retrieved from the Genome-Wide Association Study (GWAS) database. A total of 297 and 49 SNPs significantly associated with triglycerides and cholesterol-lowering drugs, respectively (P < 5 × 10-8), were identified. Similarly, data sets for non-rheumatic valve diseases (NVDs) (361,194 participants and 10,080,950 SNPs) were obtained from the GWAS database. Inverse variance weighting was used as the primary method for calculating the odds ratio (OR) and 95% confidence intervals (CI). The MR-Egger, weighted median, and weighted mode analyses were also used to test the robustness of the main results. The MR-Egger intercept test and the MR-PRESSO test were used to evaluate horizontal pleiotropy. Inverse variance weighted (IVW) results showed that both triglyceride and cholesterol-lowering medication were positively associated with NVDs (OR = 1.001, 95% CI 1.000-1.0012, P = 0.006; OR = 1.007, 95% CI 1.003-1.010; P = 0.002). This study suggests that both triglyceride and cholesterol-lowering medications are positively associated with NVDs, suggesting that lowering triglyceride levels or the use of cholesterol-lowering medications may reduce the incidence of NVDs. However, larger samples are required for further validation.

Assessing clinical and metabolic responses related to hyperlipidemia, MASLD and type 2 diabetes: sleeve versus RYGB

ObjectiveBoth Roux-en-Y gastric bypass (RYGB) and laparoscopic sleeve gastrectomy (LSG) are effective at inducing weight loss, but more information is needed on their comparative effectiveness at improving clinical/biochemical outcomes related to the presence of hyperlipidemia, metabolic dysfunction–associated steatotic liver disease (MASLD), or type 2 diabetes (T2D) at baseline. Here we aimed to assess this in real-world practice. MethodsThis is a prospective cross-sectional and cohort study of 142 patients who underwent RYGB or LSG as per clinical practice. Clinical/biochemical data were collected at baseline, prior to surgery and 12 months post–bariatric surgery. Liver biopsy was performed during surgery to diagnose MASLD. The main outcome was 12-month changes in lipid parameters, mainly total cholesterol, between types of surgery. Results: A total of107 participants underwent RYGB and 35 underwent LSG. Both groups were similar at baseline except for a higher proportion of males and waist circumference in the LSG group. At 12 months postsurgery, RYGB versus LSG resulted in a significantly lower body mass index, triglycerides, total cholesterol, and low-density lipoprotein. However, alanine aminotransferase was significantly lower in those who underwent LSG. In subgroup analyses RYGB was superior at improving lipid-related parameters in those with hyperlipidemia, whereas LSG was superior at reducing alanine aminotransferase in those with MASLD. ConclusionsRYGB versus LSG leads to greater reductions in body mass index and lipid parameters, especially in those with hyperlipidemia, whereas LSG showed greater improvements in liver enzymes in those with MASLD.

Grape Seed Proanthocyanidin Extract Attenuates Cafeteria-Diet-Induced Liver Metabolic Disturbances in Rats: Influence of Photoperiod.

This study investigated the influence of photoperiod (day length) on the efficacy of grape seed proanthocyanidin extract (GSPE) in mitigating metabolic disorders in obese rats fed a cafeteria diet. Rats were exposed to standard (L12), long (L18), or short (L6) photoperiods and treated with GSPE or vehicle. In the standard photoperiod, GSPE reduced body weight gain (50.5%), total cholesterol (37%), and triglycerides (34.8%), while increasing the expression of hepatic metabolic genes. In the long photoperiod, GSPE tended to decrease body weight gain, increased testosterone levels (68.3%), decreased liver weight (12.4%), and decreased reverse serum amino acids. In the short photoperiod, GSPE reduced glycemia (~10%) and lowered triglyceride levels (38.5%), with effects modified by diet. The standard photoperiod showed the greatest efficacy against metabolic syndrome-associated diseases. The study showed how day length affects GSPE's benefits and underscores considering biological rhythms in metabolic disease therapies.

Cardiometabolic Health in Adolescents with Obesity: The Role of Protein Intake, Diet Quality, and Physical Activity.

Background: Although adolescents with obesity have an increased risk of cardiometabolic disease, a subset maintains a healthy cardiometabolic profile. Unhealthy lifestyle behaviors may determine cardiometabolic risk. We aimed to characterize the lifestyle behaviors of adolescents with obesity, compare differences between metabolically healthy obesity (MHO) and metabolically unhealthy obesity (MUO), and assess associations between lifestyle behaviors and cardiometabolic profiles. Methods: Participants aged 10-18 years with body mass index (BMI) ≥ 95th percentile were included. Dietary intake (DI) was estimated from 3-day food records, and diet quality (DQ) was assessed using the Healthy Eating Index-Canadian Adaptation. Physical activity (PA), body composition, anthropometrics, blood markers, and blood pressure (BP) were objectively measured. MUO was defined as having high triglycerides, BP, glucose, or low high-density lipoprotein. Regression analyses were performed between lifestyle behaviors and cardiometabolic markers. Results: Thirty-nine participants (BMI z-score 2.8 [2.5-3.5], age 12.5 [10.9-13.5] years, 56.4% female) were included. A high proportion of participants failed to meet lifestyle recommendations, particularly for DQ (94.7%, n = 36), fiber (94.7%, n = 36), and PA (90.9%, n = 30). No differences in lifestyle behaviors were found between MUO (59.0%, n = 22) and MHO (41.0%, n = 16). Protein intake was negatively associated with BMI and waist circumference z-scores, fat mass index, insulin resistance, low-density lipoprotein, and C-reactive protein, whereas higher DQ was associated with lower C-reactive protein. Higher light PA levels were associated with lower total cholesterol and triglycerides. Conclusion: Adolescents with either MUO or MHO displayed low adherence to DQ, DI, and PA recommendations; no differences in lifestyle behaviors were found. Protein intake, DQ, and PA were associated with a healthier cardiometabolic profile.
