Association of Obesity and Type 2 Diabetes Mellitus With Periodontitis: A Cross-Sectional Study.

Background The relationship between obesity and type 2 diabetes mellitus (T2DM) is inevitable. The increase in the occurrence of obesity all around the globe has proportionally increased the occurrence of comorbidities. Periodontitis is a multifactorial inflammation of the periodontium attributed to dysbiosis in the subgingival microflora which may ultimately result in tooth loss. A triad between T2DM, periodontitis, and obesity is ascertained. Aim The present study focuses on investigating the association of obesity and T2DM with periodontal health. Methodology This cross-sectional study was conducted for a period of six months (September 2022 to February 2023) on 181 subjects, as per the sample size calculated by the statistician, who were previously diagnosed with T2DM and were either obese or overweight. The glycemic control was assessed on the basis of HbA1c values of the subjects. The subjects underwent bioelectrical impedance analysis along with an anthropometric examination. Full mouth examination including bleeding on probing, pocket probing depth, clinical attachment level (CAL), and oral hygiene index-simplified (OHI-S) was also checked to assess the status of periodontal health, and periodontitis was classified according to the new classification of 2017. Results The obtained data was statistically analyzed and p-value≤0.05 was considered statistically significant. The maximum prevalence of Stage III Grade C Periodontitis (34.73%) was observed in the diabetic obese group than in the diabetic overweight group. The overall anthropometric variable, abdominal circumference, waist-hip ratio, and basal metabolic index (BMI) were higher in the obese group as they displayed poor glycemic control. BMI and CAL also showed a positive correlation. Conclusion A significant association between obesity and T2DM with periodontitis was confirmed by this study. Hence, a syndemic approach needs to be formulated by the medical fraternity in collaboration with dental surgeons for the effective management of this triad.

Analysis of clinical characteristics of patients with pulmonary hypertension in Chaya County, Chamdo, Tibet.

Pulmonary hypertension (PH) is a critical health issue marked by high blood pressure in the pulmonary arteries, with limited data on its clinical characteristics in the Tibetan population. The objective of this study was to examine the clinical characteristics of PH patients among Tibetan population residing in Chaya County, Changdu, Tibet. This was a retrospective cross-sectional study. A total of 94 PH patients diagnosed via echocardiography at the Internal Medicine Department of Chaya County People's Hospital in Changdu (Tibet, China) between March 2019 and October 2020 were included. Additionally, 52 non-PH inpatients were selected as the control group. Patient medical records were reviewed for demographic and clinical data, lab results, and echocardiographic findings. Student's t-test/chi-squared test between PH and control group, one-way analysis of variance (ANOVA) among control and PH subgroups, Pearson's and Spearman's correlation coefficient were used to analysis the results. Out of 1,689 inpatients in the Internal Medicine Department, 94 were identified as PH patients for analysis. The average hemoglobin level among PH patients (150.64±21.67 g/L) was similar to that observed in the normal population (146.65±17.51 g/L) at high altitude (P=0.28). Abnormal liver function indexes were observed, with 51.06% of PH patients exhibiting hyperuricemia (P<0.001 compared to control's 15.38%). The PH group demonstrated significantly elevated red blood cell distribution width (RDW)-standard deviation (50.59±6.49 vs. 43.67±3.40 fL, P<0.001) and RDW-coefficient of variation of (16.18%±3.04% vs. 13.52%±1.32%, P<0.001), along with a decreased platelet level compared to the control group [(202.55±73.67) vs. (256.63±72.85) ×109/L]. Furthermore, echocardiographic indicators related to right heart function showed correlations with red blood cell count, bilirubin, albumin, low-density lipoprotein cholesterol, and high-density lipoprotein cholesterol (multiple significant correlation coefficient r, magnitude from 0.22 to 0.54). Chronic pulmonary disease and left heart disease were identified as common etiologies of PH among Tibetan patients residing in high-altitude regions. The Tibetan population residing in high-altitude regions and diagnosed with PH displayed abnormal changes in numerous liver functional and metabolic indices, which were correlated with the morphological indices observed via cardiac ultrasound.

Effects of vitamin D supplementation on diabetic foot ulcer healing: a meta-analysis.

To systematically review the effect of vitamin D supplementation on diabetic foot ulcer (DFU) healing. The PubMed, Web of Science, Science direct, Ebsco host, CNKI, WanFang, VIP, and CBM databases were electronically searched to collect randomized controlled trials (RCTs) on the impact of vitamin D supplementation on DFUs from inception to 19 November 2022. Two researchers independently screened the literature, extracted the data and assessed the risk of bias of the included studies. Meta-analysis was then performed by using RevMan 5.3 software. A total of seven studies involving 580 patients were included. The results of meta-analysis showed that compared with control group, the wound healing efficiency rate (RR = 1.42, 95%CI 1.03 to 1.95, P= 0.03) and wound reduction rate (MD = 13.11, 95%CI 4.65 to 21.56, P < 0.01) of the experimental group were higher; the change values of the wound area (MD = -3.29, 95%CI -4.89 to 1.70, P < 0.01) and 25 (OH) D (MD = 9.63, 95%CI 6.96 to 12.31, P < 0.01) were larger. Supplementation of vitamin D on DFU patients can improve glucose metabolism and insulin indexes: hemoglobin A1c (MD = -0.44, 95%CI -0.62 to -0.26, P < 0.01), fasting insulin (MD = -3.75, 95%CI -5.83 to -1.67, P < 0.01), HOMA - β (MD = -5.14, 95%CI -8.74 to -1.54, P < 0.01), and quantitative insulin sensitivity check index (MD = 0.02, 95%CI 0.01 to 0.02, P < 0.01). It can also improve inflammation and oxidative stress markers: high sensitivity C-reactive protein (MD = -0.83, 95%CI -1.06 to -0.59, P < 0.01), erythrocyte sedimentation rate (MD = -15.74, 95%CI -21.78 to -9.71, P<0.01), nitric oxide (MD = 1.81, 95%CI 0.07 to 3.55, P= 0.04), and malondialdehyde (MD = -0.43, 95%CI -0.61 to -0.24, P<0.01). There was no statistically significant difference in changes of fasting plasma glucose, homeostasis model of assessment-insulin resistance, total antioxidant capacity, glutathione, very low density lipoprotein cholesterol, low density lipoprotein cholesterol, and high density lipoprotein cholesterol (P>0.05). The current evidence suggests that vitamin D supplementation can significantly promote DFU healing by lowering blood sugar and alleviating inflammation and oxidative stress. Key messages What is already known on this topic Diabetic foot ulcer (DFU) is a major complication of diabetes mellitus, with high morbidity, mortality and resource utilization. Vitamin D has the effect of lowering blood sugar, improving insulin sensitivity, and increasing anti-inflammatory response. Clinical research on vitamin D supplementation for the treatment of DFU is increasing, but due to the lack of combing and integration, the actual efficacy of vitamin D in patients is unclear. What this study adds This meta-analysis has shown that vitamin D supplementation can significantly promote DFU healing by lowering blood glucose and alleviating inflammation and oxidative stress. How this study might affect research, practice or policy This study preliminarily found the effectiveness of vitamin D supplementation on the healing of DFU, which can provide a reference for the treatment of DFU by medical staff.

Effects of inulin on intestinal flora and metabolism-related indicators in obese polycystic ovary syndrome patients

ContextPolycystic ovary syndrome (PCOS), a common endocrine disorder in women of reproductive age, is closely associated with chronic low-grade inflammation and metabolic disturbances. In PCOS mice, dietary inulin has been demonstrated to regulate intestinal flora and inflammation. However, the efficacy of dietary inulin in clinical PCOS remains unclear.ObjectiveThe intestinal flora and related metabolic indexes of obese patients with polycystic ovary syndrome (PCOS) after 3 months of inulin treatment were analyzed.Setting and designTo analyze the intestinal flora and related metabolic indexes in healthy controls and obese patients with polycystic ovary syndrome after 3 months of inulin treatment.ResultsThe results showed that dietary inulin improved sex hormone disorders, reduced BMI and WHR levels in obese women with PCOS. In addition, the inulin intervention reduced plasma TNF-α, IL-1β, IL-6, and MCP-1levels. Inulin intervention increased the abundance of Actinobacteria, Fusobacteria, Lachnospira, and Bifidobacterium, as well as decreased the ratio of F/B and the abundance of proteobacteria, Sutterella, and Enterobacter. Correlation analyses showed a strong relationship among plasma inflammatory factors, sex steroid hormones, and the intestinal flora of patients.ConclusionsDietary inulin may improve obese PCOS women disease through the gut flora–inflammation–steroid hormone pathway.The clinical trial registration number: ChiCTR-IOR-17012281.

Associations of dietary inflammation index and composite dietary antioxidant index with preserved ratio impaired spirometry in US adults and the mediating roles of triglyceride-glucose index: NHANES 2007–2012

BackgroundPrevious studies have shown that inflammatory and antioxidant dietary patterns can modify the risk of COPD, yet few studies have examined the association of these diets with its early signs (PRISm), and the potential role of metabolic disorders remains to be elucidated. MethodsData from 9529 individuals who participated in the 2007–2012 National Health and Nutrition Examination Survey (NHANES) were analyzed. The Dietary Inflammation Index (DII) and the Dietary Antioxidant Composite Index (CDAI) were assessed using 24-h dietary recall, multiple metabolic indicators were calculated according to biochemical markers, and lung function parameters defined PRISm cases. Individual and joint effects of DII and CDAI were evaluated by generalized linear models and binary logistic regression models, and mediation effects of metabolic indicators were further explored by causal mediation analysis. ResultsIncreased DII was associated with decreased lung function (FEV1: β = −18.82, FVC: β = −29.2; OR = 1.04) and increased metabolic indicators (β = 0.316, 0.036, 0.916, 0.033, and 0.145 on MAP, UA, TC, TyG, and MS, respectively). Contrary to this, CDAI were positively and negatively associated with lung function (FEV1: β = 3.42; FVC: β = 4.91; PRISm: OR = 0.99) and metabolic indicators (β < 0), respectively. Joint effects of DII and CDAI indicated the minimal hazard effects of DII on TyG (β = −0.11), FEV1 (β = 72.62), FVC (β = 122.27), and PRISm (OR = 0.79) in subjects with high CDAI when compared with those with low CDAI (low DII + high CDAI vs. high DII + low CDAI). Furthermore, TyG mediated 13.74 %, 8.29 %, and 21.70 % of DII- and 37.30 %, 20.90 %, and 12.32 % of CDAI-FEV1, -FVC, and -PRISm associations, respectively. ConclusionsThese findings indicated that CDAI can attenuate the adverse effects of DII on metabolic disorders and lung function decline, which provides new insight for diet modification in preventing early lung dysfunction.

Multifaceted association of overweight and metabolically unhealthy with the risk of Barrett's esophagus in the UK Biobank cohort

The association of overweight/obesity and metabolically unhealthy (MU) with the risk of developing Barrett's esophagus (BE) remains uncertain. We evaluated whether MU and overweight/obesity are associated with increased BE incidence and whether they have a synergistic impact on BE development. We analyzed the body mass index (BMI) and metabolic indicators at baseline of 402,510 individuals from the UK Biobank with no history of BE. Overweight/obesity and MU were defined as BMI ≥ 25.0 kg/m2 and presence of ≥ 1 MU indicators, respectively. Accordingly, the participants were categorized into four groups: (1) metabolically healthy non-overweight/obesity (MHNO), (2) metabolically unhealthy non-overweight/obesity (MUNO), (3) metabolically healthy overweight/obesity (MHO), and (4) metabolically unhealthy overweight/obesity (MUO). During a median follow-up of 13.5 years, 6195 (1.5%) individuals were newly diagnosed with BE. Among them, 39,281 (9.8%), 92,000 (22.9%), 25,297 (6.3%), and 245,932 (61.1%) individuals were classified as MHNO, MUNO, MHO, and MUO, respectively. In Cox regression analyses, both MU and overweight/obesity were independently associated with BE incidence. Moreover, BE incidence was significantly higher in the MUNO, MHO, and MUO groups, compared to the MHNO group. MU and overweight/obesity are independent risk factors for BE and have a synergistic effect on BE development.

ДИНАМИЧЕСКИЙ АНАЛИЗ КЛИНИКО-МЕТАБОЛИЧЕСКИХ ПОКАЗАТЕЛЕЙ У ПОДРОСТКОВ С ОЖИРЕНИЕМ В ГЕНДЕРНОМ АСПЕКТЕ

Obesity in children and adolescents makes a significant contribution to the comorbidity of the pathology of the adult population, which is primarily associated with the development of metabolic syndrome. Of particular interest are gender differences in the detection and progression of symptoms of metabolic disorders. The purpose of the study was to conduct a dynamic analysis of clinical and metabolic indicators in adolescents with obesity in the gender aspect. The study reflects the dynamics of anthropometric indicators (body mass index and waist circumference to hip circumference ratio), metabolic indicators of carbohydrate and lipid profiles in the gender aspect. At the same time, no statistically significant gender differences were found both during the initial examination and after 12 months, however, there was a violation of glucose tolerance in girls in dynamics, which is probably associated with the progression of obesity. Correlations showing significant differences between the anthropome are interesting. Thus, among young men, the average strength of the relationship between age and glucose levels after exercise (correlation coefficient -0,59) and blood insulin content (correlation coefficient 0,55) turned out to be significant. At the same time, higher BMI values were accompanied by an increase in fasting blood glucose (correlation coefficient 0,6). Similar direct relationships between BMI and indicators of carbohydrate and lipid metabolism were observed in girls: the higher the BMI, the higher the levels of glucose after exercise, insulin and triglycerides in the blood (correlation coefficients 0,63, 0,81 and 0,52).

Effects of T-2 and deoxynivalenol mycotoxins on mouse spinal bone growth and integrity

Kashin-Beck Disease (KBD), an osteoarticular disorder, is influenced by various factors, including exposure to Deoxynivalenol (DON) and T-2 mycotoxins. This study systematically explored the impact of these mycotoxins on the development and structural resilience of spinal structures in mice, examining both isolated and combined effects. The experiment involved 72 male mice divided into nine groups, each subjected to varying concentrations of T-2, DON, or their combinations over four weeks. Rigorous monitoring included body weight, key indicators of bone metabolism, and cellular activities essential to bone health. Comprehensive evaluations using biomechanical analysis, x-ray, and micro-computed tomography (micro-CT) were conducted to assess alterations in spinal structure.The findings revealed a pivotal aspect: mice exhibited a dose-dependent decline in body weight when exposed to individual mycotoxins, while simultaneous exposure produced an unanticipated antagonistic effect. Moreover, decreases were noted in levels of calcium, phosphorus, and vitamin D, coupled with changes in the activities of osteoblasts (increased) and osteoclasts (decreased), all intricately tied to the toxins' dosages and combinations. Notably, variations in the biomechanical properties corresponded with the mycotoxin dosage and blend, showing a decline in biomechanical strength. Micro-CT analyses further substantiated the profound toxic impact of the toxin dosage and mixtures on both the cortical and trabecular components of the spinal structures.In summary, this investigation unequivocally illuminates the dose- and ratio-dependent deleterious impacts of DON and T-2 mycotoxins on the growth and structural soundness of spinal structures in mice. These findings highlight the urgent need for a comprehensive understanding of the potential hazards these toxins pose to bone health, providing invaluable guidance for future toxicological research and public health strategies.

The synergistic effect of triglyceride-glucose index and HbA1c on blood pressure control in patients with hypertension: a retrospective cohort study

Triglyceride-Glucose Index (TyG index) and HbA1c are metabolic risk factors associated with insulin resistance (IR), which have been confirmed to be independently correlated with the incidence of hypertension. However, there is limited research specifically focusing on the interaction between these two metabolic risk factors in hypertensive populations. Currently, it remains unclear how the metabolic indicators TyG index and HbA1c affect BP control in individuals with hypertension. This study aims to investigate the value and interaction of TyG index and HbA1c in blood pressure (BP) control among hypertensive patients. The results are conducive to enhancing the effectiveness of clinical BP control for individuals with hypertension. This cohort study included 99,336 adults diagnosed with hypertension. Participants were grouped according to the median of TyG index and HbA1c. The main endpoint is inadequate BP control. Multivariable-adjusted risk ratios and multivariable Cox regression analysis were used to represent the relationship between BP control levels and metabolic risk factors. Finally, we evaluated the interaction between TyG index and HbA1c in the population with inadequate BP control. This study confirmed that TyG index and HbA1c, as metabolic risk factors, are independently associated with poor BP control (P < 0.05). In multivariable Cox regression analysis, it was found that TyG index and HbA1c were significantly associated with poor BP control. In the male elderly population, HbA1c was significantly associated with poor BP control (P = 0.029).

Beta-Blockers of Different Generations: Features of Influence on the Disturbances of Myocardial Energy Metabolism in Doxorubicin-Induced Chronic Heart Failure in Rats.

Beta-blockers are first-line drugs in the treatment of chronic heart failure (CHF). However, there is no consensus on the specific effects of the beta-blockers of the I-III generation on energy metabolism in CHF. The aim of this study is to conduct a study of beta-blockers of different generations on myocardial energy metabolism in experimental CHF. CHF was modeled in white outbred rats by administering doxorubicin. The study drugs were administered intragastrically-new drug Hypertril (1-(β-phenylethyl)-4-amino-1,2,4-triazolium bromide)-3.5 mg/kg, Metoprolol-15 mg/kg, Nebivolol -10 mg/kg, Carvedilol 50 mg/kg, and Bisoprolol, 10 mg/kg. In the myocardium, the main indices of energy metabolism were determined-ATP, ADP, AMP, malate, lactate, pyruvate, succinate dehydrogenase (SDH) activity, and NAD-dependent malate dehydrogenase (NAD-MDH) activity. Traditional second-generation beta-blockers (Metoprolol and Bisoprolol) did not affect the studied indices of energy metabolism, and third-generation beta-blockers with additional properties-Carvedilol and, especially, Nebivalol and Hypertril-improved myocardial energy metabolism. The obtained results will help to expand our understanding of the effect of beta-blockers of various generations used to treat cardiovascular diseases on energy metabolism, and are also an experimental justification for the practical choice of these drugs in the complex therapy of CHF.

Analysis of metabolic alterations as 30 days intensive care mortality predictors for patients undergoing continuous renal replacement therapy

BackgroundAcute kidney injury patients on continuous renal replacement therapy are subjected to alterations in metabolism, which in turn are associated with worse clinical outcome and mortality. The aim of this study is to determine which metabolism indicators can be used as independent predictors of 30 days intensive care unit (ICU) mortality. MethodsThis was a prospective observational study on critical care patients on renal replacement therapy. Integrated approach of metabolism evaluation was used, combining the energy expenditure measured by indirect calorimetry, bioelectrical impedance provided fat free mass index (FFMI), amino acid and glucose concentrations. ICU mortality was defined as all cause 30 days mortality. Regression analysis was conducted to determine the conventional and metabolism associated predictors of mortality. ResultsThe study was conducted between the 2021 March and 2022 October. 60 high mortality risk patients (APACHE II of 22.98±7.87, 97% on vasopressors, 100% on mechanical ventilation) were included during the period of the study. The rate of 30 days ICU mortality was 50% (n=30). Differences across survivors and non-survivors in metabolic predictors were noted in energy expenditure (kcal/kg/day) (19.79 ±5.55 vs 10.04 ±3.97 p=0.013), amino acid concentrations (mmol/L) (2.40 ±1.06 vs 1.87 ±0.90 p=0.040) and glucose concentrations (mmol/L) (7.89 ±1.90 vs 10.04 ±3.97 p=0.010). No differences were noted in FFMI (23.38 ±4.25 vs 21.95 ±3.08 p=0.158). In the final linear regression analysis model, lower energy expenditure (exp(B)= 0.852 CI95%: 0.741-0.979 p=0.024) and higher glucose (exp(B)=1.360 CI95%: 1.013-1.824 p=0.041) remained as independent predictors of the higher mortality. ConclusionThe results of the study imply strong association between the metabolic alterations and ICU outcome. Our findings suggest that lower systemic amino acid concentration, lower energy expenditure and higher systemic glucose concentration are predictive of 30 days ICU mortality.

Elevated TyG-BMI index predicts incidence of chronic kidney disease

Chronic kidney disease (CKD) represents a significant global public health issue, with its incidence and prevalence escalating annually. Metabolic disorders are one of the major etiological factors of CKD. This study investigates the relationship between the emerging metabolic index triglyceride-glucose body mass index (TyG-BMI) and the onset of CKD. Our study enrolled 3,485 healthy participants (1,576 men and 1,909 women), with a follow-up period of 3 years. The primary outcome was the emergence of CKD, defined by an eGFR less than 60 mL/(min × 1.73 m2) or the onset of proteinuria. To examine the TyG-BMI and CKD onset relationship, we used univariate and multivariate logistic regression analyses, stratified analyses, and receiver operating characteristic (ROC) curves. After a three-year follow-up, CKD developed in 2% (n = 70) of the participants. Subjects were divided into three equal groups based on their TyG-BMI values, from lowest to highest. After adjusting for potential confounders, the highest TyG-BMI group exhibited a multifactor-adjusted odds ratio (OR) of 4.24 (95% CI 1.30–13.78, P = 0.016) compared to the lowest group. Stratified analyses revealed that the association between TyG-BMI and CKD onset was stronger among females, individuals younger than 60 years, and those with a BMI ≥ 24 kg/m2. Furthermore, TYG-BMI was effective in predicting the incidence of CKD. Our findings indicate that TyG-BMI is an independent risk factor for the onset of CKD and that assessment of TyG-BMI may be useful for the early identification of individuals at high risk for CKD.

Association between cardiometabolic index and testosterone levels in adult men: NHANES 2011-2016.

Exploring the relationship between the cardiometabolic index (CMI) and serum testosterone levels as well as testosterone deficiency in American adult males. Additionally, comparing the diagnostic value of the CMI with several common obesity and metabolism indices for identifying testosterone deficiency. This cross-sectional study was conducted using data from the National Health and Nutrition Examination Survey (NHANES) from 2011 to 2016. Serum testosterone levels and testosterone deficiency were used as dependent variables, with the cardiometabolic index as the independent variable. Multivariable regression was used to assess the relationship between the independent and dependent variables, while subgroup analyses were performed to ensure the stability of the results. Smooth curve fitting was utilized to evaluate the nonlinear relationship between the CMI and testosterone levels. Receiver operating characteristic curves (ROC) were plotted for several obesity and metabolism prediction indices and the area under the curve was calculated to compare the specificity and sensitivity of each diagnostic index in the diagnosis of testosterone deficiency. Among 3541 adult male participants, CMI is negatively associated with serum testosterone levels and positively associated with testosterone deficiency. In the fully adjusted model, for every unit increase in CMI, serum testosterone decreased by 14.89 ng/dl. Comparing the highest quartile to the lowest quartile of CMI, each unit increase in CMI, serum testosterone decreased by 98.58 ng/dl. Furthermore, each unit increase in CMI was associated with a 16% increase in incidence of testosterone deficiency. By plotting the ROC curves, we found that the AUCs for Lipid Accumulation Product (LAP), Body Mass Index (BMI), Weight Adjusted Waist Index (WWI), CMI, Visceral Adiposity Index (VAI) and Triglyceride glucose index (TyG) were 0.73, 0.72, 0.71, 0.69, 0.66, and 0.66 respectively. Elevated levels of CMI are associated with lower testosterone levels and an increased risk of testosterone deficiency. The predictive value of the LAP was superior to that of CMI, while the predictive value of CMI was higher than VAI and TyG.

A Randomized Controlled Trial Comparing the Effects of Vilazodone, Escitalopram, and Vortioxetine Monotherapy on the Metabolic Parameters in Patients With Major Depressive Disorder.

The coexistence of major depressive disorder (MDD) and metabolic illness could culminate in an aberrant metabolic profile. Individuals with MDD and type 2 diabetes mellitus (T2DM) are more likely to have impaired metabolic indicators. Effective antidepressant therapy can alleviate depressive symptoms and metabolic abnormalities. We focused on the effects of vilazodone, escitalopram, and vortioxetine on metabolic indices. Our research aimed to examine changes after 16 weeks of intervention in the glycemic indices, serum creatinine, lipid profile, hepatic parameters, and the Hamilton Depression Rating Scale (HDRS) 17-item version. A three-arm, randomized, open-label trial with 96 MDD patients was executed. Participants were divided into three distinct groups in a 1:1:1 ratio for 16 weeks and issued tablets of vilazodone (20-40 mg/day), escitalopram (10-20 mg/day), or vortioxetine (5-20 mg/day). Vilazodone and vortioxetine were the two test medications, while escitalopram served as the control. We stratified the participants as non-diabetics and diabetics. Follow-up appointments were slated four weeks after the initial visit. HDRS scores and other metabolic indicators were assessed at each visit in the per-protocol (PP) population. After 12 weeks, glycated hemoglobin (HbA1c) levels were measured. Lower HDRS scores indicated that depression-related symptoms had improved. We investigated the relationship between the 16-week differences in the fasting blood sugar(FBS) and HDRS scores. The Kruskal-Wallis test, Bonferroni correction, and Pearson correlation were all used in our analysis. We registered our trial prospectively in the Clinical Trial Registry of India (CTRI) (2022/07/043808). Of the 134 people we screened, 119 (81.34%) were deemed eligible. The PP population included 96 (88.07%) of those who completed the 16-week study. The population's average age was 46.3 ± 6.2 years. Across all study groups, the median baseline HDRS score was 30.0 (p = 0.964). At 16 weeks, the equivalent scores dropped to 15.0, 14.0, and 13.0 (p = 0.002). The median FBS levels at baseline and 16 weeks were 100.5, 104.0, and 98.0 (p = 0.491) and 91.5, 98.5, and 91.5 (p = 0.561), respectively. The post hoc analysis manifested no statistically significant changes between any parameters. Except for the reductions in glycemic indices in diabetic patients, no other data differed significantly. There was a positive relationship between FBS and HDRS scores. Irrespective of the diabetic situation, all three drugs substantially lowered HDRS scores. People with diabetes experienced noticeable declines in glycemic indices. Despite this, the patients' other metabolic indicators showed no significant alterations. We urge additional research with a larger sample size to investigate these medications' long-term impact on various metabolic indicators.

Nuclear-Magnetic-Resonance-Spectroscopy-Derived Serum Biomarkers of Metabolic Vulnerability Are Associated with Disability and Neurodegeneration in Multiple Sclerosis.

Metabolic vulnerabilities can exacerbate inflammatory injury and inhibit repair in multiple sclerosis (MS). The purpose was to evaluate whether blood biomarkers of inflammatory and metabolic vulnerability are associated with MS disability and neurodegeneration. Proton nuclear magnetic resonance spectra were obtained from serum samples from 153 healthy controls, 187 relapsing-remitting, and 91 progressive MS patients. The spectra were analyzed to obtain concentrations of lipoprotein sub-classes, glycated acute-phase proteins, and small-molecule metabolites, including leucine, valine, isoleucine, alanine, and citrate. Composite indices for inflammatory vulnerability, metabolic malnutrition, and metabolic vulnerability were computed. MS disability was measured on the Expanded Disability Status Scale. MRI measures of lesions and whole-brain and tissue-specific volumes were acquired. Valine, leucine, isoleucine, alanine, the Inflammatory Vulnerability Index, the Metabolic Malnutrition Index, and the Metabolic Vulnerability Index differed between healthy control and MS groups in regression analyses adjusted for age, sex, and body mass index. The Expanded Disability Status Scale was associated with small HDL particle levels, inflammatory vulnerability, and metabolic vulnerability. Timed ambulation was associated with inflammatory vulnerability and metabolic vulnerability. Greater metabolic vulnerability and inflammatory vulnerability were associated with lower gray matter, deep gray matter volumes, and greater lateral ventricle volume. Serum-biomarker-derived indices of inflammatory and metabolic vulnerability are associated with disability and neurodegeneration in MS.

Effect of oral metformin on gut microbiota characteristics and metabolite fractions in normal-weight type 2 diabetic mellitus patients.

To analyze the effect of oral metformin on changes in gut microbiota characteristics and metabolite composition in normal weight type 2 diabetic patients. T2DM patients in the cross-sectional study were given metformin for 12 weeks. Patients with unmedicated T2DM were used as a control group to observe the metrics of T2DM patients treated with metformin regimen. 16S rDNA high-throughput gene sequencing of fecal gut microbiota of the study subjects was performed by llumina NovaSeq6000 platform. Targeted macro-metabolomics was performed on 14 cases of each of the gut microbiota metabolites of the study subjects using UPLC-MS/MS technology. Correlations between the characteristics of the gut microbiota and its metabolites, basic human parameters, glycolipid metabolism indicators, and inflammatory factors were analyzed using spearman analysis. Glycolipid metabolism indexes and inflammatory factors were higher in normal-weight T2DM patients than in the healthy population (P<0.05), but body weight, BMI, waist circumference, and inflammatory factor concentrations were lower in normal-weight T2DM patients than in obese T2DM patients (P<0.05). Treatment with metformin in T2DM patients improved glycolipid metabolism, but the recovery of glycolipid metabolism was more pronounced in obese T2DM patients. None of the differences in α-diversity indexes were statistically significant (P>0.05), and the differences in β-diversity were statistically significant (P <0.05). Community diversity and species richness recovered after metformin intervention compared to before, and were closer to the healthy population. We found that Anaerostipes/Xylose/Ribulose/Xylulose may play an important role in the treatment of normal-weight T2DM with metformin by improving glycemic lipids and reducing inflammation. And Metformin may play a role in obese T2DM through Romboutsia, medium-chain fatty acids (octanoic acid, decanoic acid, and dodecanoic acid). Gut microbial dysbiosis and metabolic disorders were closely related to glucose-lipid metabolism and systemic inflammatory response in normal-weight T2DM patients. Metformin treatment improved glucose metabolism levels, systemic inflammation levels in T2DM patients, closer to the state of healthy population. This effect may be mediated by influencing the gut microbiota and microbial host co-metabolites, mainly associated with Anaerostipes and xylose/Ribulose/Xylulose. Metformin may exert its effects through different pathways in normal-weight versus obese T2DM patients.

The consumption of ultra-processed foods was associated with adiposity, but not with metabolic indicators in a prospective cohort study of Chilean preschool children

BackgroundIncreasing consumption of ultra-processed foods (UPF) has been identified as a risk factor for obesity and various diseases, primarily in adults. Nonetheless, research in children is limited, especially regarding longitudinal studies with metabolic outcomes. We aimed to evaluate the longitudinal association between consumption of UPF, adiposity, and metabolic indicators in Chilean preschool children.MethodsWe conducted a prospective analysis of 962 children enrolled in the Food and Environment Chilean Cohort (FECHIC). Dietary data were collected in 2016 at age 4 years with 24-h recalls. All reported foods and beverages were classified according to the NOVA food classification, and the usual consumption of UPF in calories and grams was estimated using the Multiple Source Method. Adiposity (z-score of body mass index [BMI z-score], waist circumference [WC], and fat mass [in kg and percentage]) and metabolic indicators (fasting glucose, insulin, HOMA-IR, triglycerides, total cholesterol, and cholesterol fractions) were measured in 2018, at the age of 6 years. Linear regression models ((0) crude, (1) adjusted for covariables, and (2) adjusted for covariables plus total caloric intake) were used to evaluate the association between UPF and outcomes. All models included inverse probability weights to account for the loss to the follow-up.ResultsAt 4 years, usual consumption of UPF represented 48% of the total calories and 39% of the total food and beverages grams. In models adjusted for covariables plus caloric intake, we found a positive association between UPF and BMI z-score (for 100 kcal and 100 g, respectively: b = 0.24 [95%CI 0.16–0.33]; b = 0.21 [95%CI 0.10–0.31]), WC in cm (b = 0.89 [95%CI 0.41–1.37]; b = 0.86 [95%CI 0.32–1.40]), log-fat mass in kg b = 0.06 [95%CI 0.03–0.09]; b = 0.04 [95%CI 0.01–0.07]), and log-percentage fat mass (b = 0.03 [95%CI 0.01–0.04]; b = 0.02 [95%CI 0.003–0.04]), but no association with metabolic indicators.ConclusionsIn this sample of Chilean preschoolers, we observed that higher consumption of UPF was associated with adiposity indicators 2 years later, but not with metabolic outcomes. Longer follow-up might help clarify the natural history of UPF consumption and metabolic risks in children.

Exploring the Impact of Astaxanthin Supplementation in Conjunction with a 12-Week CrossFit Training Regimen on Selected Adipo-Myokines Levels in Obese Males.

Obesity is associated with an exacerbated metabolic condition that is mediated through impairing balance in the secretion of some adipo-myokines. Therefore, the objective of the present study was to explore the impact of astaxanthin supplementation in conjunction with a 12-week CrossFit training regimen on some selected adipo-myokines, insulin insensitivity, and serum lipid levels in obese males. This study is a randomized control trial design; 60 obese males were randomly divided into four groups of 15, including the control group (CG), supplement group (SG), training group (TG), and combined training and supplement group (TSG). The participants were subjected to 12 weeks of astaxanthin (AST) supplementation [20 mg/d capsule, once/d] or CrossFit training or a combination of both interventions. The training regimen comprised 36 sessions of CrossFit, each lasting 60 min, conducted three times per week. The metabolic indices, body composition, anthropometrical, cardio-respiratory, and also some plasma adipo-myokine factors, including decorin (DCN), activin A, myostatin (MST), transforming growth factor (TGF)-β1, and follistatin (FST), were examined 12 and 72 h before the initiation of the main interventional protocols, and then 72 h after the final session of the training protocol. There was no significant difference in the baseline data between the groups (p > 0.05). There were significant interactions between group x time for DCN (η2 = 0.82), activin A (η2 = 0.50), FST (η2 = 0.92), MST (η2 = 0.75), and TGFB-1 (η2 = 0.67) (p < 0.001 for all the variables). Significantly changes showed for DCN in TSG compared to TG and SG and also TG compared to SG (p = 0.0001); for activin A in SG compared to TG (p = 0.01) and TSG (p = 0.002); for FST in SG compared to TG and TSG (p = 0.0001), also in TSG compared to TG (p = 0.0001); for MST in SG, TG, and TSG compared to CG (p = 0.0001) and also in TSG compared to SG (p = 0.0001) and TG (p = 0.001); for TGFB-1 in SG, TG, and TSG compared to CG (p = 0.0001) and also TSG compared to SG (p = 0.0001) and TG (p = 0.001). The 12-week CrossFit training concurrent with AST supplementation reduced anthropometric and metabolic factors and also serum lipid levels while producing positive changes in body composition and cardiovascular factors. Increased FST and DCN and reduced activin A, MST, and TGF-β1 were other affirmative responses to both interventions.

Telomere length in young and middle-aged patients: relationship with cardiovascular risk factors

Aim. To evaluate the relationship between leukocyte telomere length (LTL) and cardiovascular risk factors in young and middle-aged patients without cardiovascular disease (CVD).Material and methods. This cross-sectional study involved 450 patients aged 30 [21;42] years. Risk factors and possible exclusion criteria was assessed through questionnaires and anthropometric examination. In all subjects, glucose concentration and lipid profile were assessed using the CardioChekPA express analyzer (USA, 2017), followed by calculation of integral metabolic indices: visceral adiposity index (VAI), body fat percentage, body adiposity index (BAI), lipid accumulation product (LAP). LTL was measured in whole blood samples using fluorimetry (Qubit 4 Singapore 2020) and reverse transcription polymerase chain reaction (QIAamp Blood Mini Kit, German 2022). Statistical analysis was carried out using the Statistica 10 program.Results. The prevalence of the studied risk factors in the main group corresponded to the general population. According to the correlation analysis, LTL was associated with age (r=-0,26; p&lt;0,05), smoking (r=-0,35; p&lt;0,05), obesity (r=-0,19; p&gt;0,05), neck circumference (NC) (r=-0,53; p&lt;0,05), diastolic blood pressure (r=-0,31; p&lt;0,05), cholesterol (r=-0,64; p&lt;0,05), high-density lipoproteins (HDL) (r=0,59; p&lt;0,05) and low-density lipoproteins (r=-0,52; p&lt;0,05), triglycerides (r=-0,46; p&lt;0,05), glucose (r=-0,33; p&lt;0,05), LAP (r=-0,4; p&lt;0,05), VAI (r=-0,57; p&lt;0,05) and BAI (r=-0,32; p&lt;0,05). According to the multivariate regression analysis, LTL was associated with age (B=-0,04, Std. Err. of B=0,02, p=0,03), smoking (B=-0,87, Std. Err. of B=0,26, p=0,001), NC (B=-0,23, Std. Err. of B=0,07, p=0,001), total cholesterol levels (B=-0,37, Std. Err. of B=0,87, p&lt;0,001), HDL (B=0,59, Std. Err. of B=0,24, p=0,018), LAP (B=-0,01, Std. Err. of B=0,02, p&lt;0,011), VAI (B=-0,37, Std. Err. of B=0,16, p=0,025).Conclusion. LTL is interconnected with cardiovascular risk factors, which determines the significance of their participation in CVD development and biological aging in young and middle-aged people.
