Preparing the soil: Adjusting the metabolic health of patients with chronic wounds and musculoskeletal diseases.

In recent years, systemic inflammation has emerged as a pivotal player in the development and progression of various degenerative diseases. This complex, chronic inflammatory state, often undetected, can have far-reaching consequences for the body's physiology. At the molecular level, markers such as C-reactive protein, cytokines and other inflammatory mediators serve as indicators of systemic inflammation and often act as predictors of numerous musculoskeletal diseases and even certain forms of cancer. The concept of 'meta-inflammation', specifically referring to metabolically triggered inflammation, allows healthcare professionals to understand inflammatory responses in patients with metabolic syndrome. Driven by nutrient excess and the expansion of adipose tissue, meta-inflammation is closely associated with insulin resistance, further propagating the metabolic dysfunction observed in many Western societies. Wound persistence, on the other hand, exacerbates the detrimental effects of prolonged inflammation at the local level. Acute inflammation is a beneficial and essential process for wound healing and infection control. However, when inflammation fails to resolve, it can impede the healing process, leading to chronic wounds, excessive scarring and even the activation of fibrotic pathways. This approach significantly reduces the efficacy of regenerative biological therapies. Our review focuses on the vital role of proteins, vitamins and minerals in collagen synthesis and cell proliferation for tissue healing. We also examine hormonal influences on regeneration, noting the negative effects of imbalances, and emphasize glucose regulation's importance in creating a stable environment for chronic wound healing.

Social conditions impact functional outcome in patients with hand osteoarthritis: the low-income hand osteoarthritis (LIHOA) cohort.

BACKGROUND: Hand osteoarthritis (HOA) is a highly prevalent disease that may be impacted by social inequalities. Few studies in HOA are from underdeveloped regions. We intend to contribute to fill this gap presenting clinical characteristics of our low-income HOA cohort (LIHOA). METHODS: Data from 119 patients with a HOA diagnosis fulfilling ACR criteria seen between August 2019 and May 2023 in Fortaleza/Brazil. Evaluations included pain (VAS, visual analogue scale), X-ray (KL, Kellgren-Lawrence), grip and pinch strength (KgF), Cochin hand functional scale (CHFS), FIHOA, and SF-12 scores. Social data included monthly (<1, 1≥/<3, ≥3 MW) minimum wage earnings, occupation, and literacy [4 IF nodes. OA in other joints: 37 (36.2%) spine, 28 (29.4%) knee, 21 (20.5%) bunions. Functional impairment was mild [8 (5-14) median FIHOA]. Median serum CRP was 0.2 mg/dL (0.1-0.4) with 14 (20%) patients above reference value. Mean total KL score was 27.6 ± 13.6 with 21 (23%), 38 (41.7%), and 33 (36.2%) KL2, KL3, and KL4, respectively; 51 (54.8%) and 42 (45.2%) patients declared 9SY including 37.2% with a university degree. Individuals earning <3 MW had lower pinch (p < 0.004) and grip strength (p < 0.01), and higher FIHOA scores (p < 0.007), as compared to ≥3 MW earning group. Literacy or occupation did not impact outcome. SYSADOA were used by 13 (12.7%), 6 used oral and 3 topical anti-inflammatory drugs and 2 used 5 mg/d prednisone. CONCLUSION: Clinical characteristics in our LIHOA cohort mirror those reported in affluent regions. Socioeconomic disparities influenced functional outcome in LIHOA cohort.

Oral glucose tolerance test curve shape in Mexican children and adolescents with and without obesity.

OBJECTIVES: Mexican children with obesity are at a higher risk of developing type 2 diabetes mellitus (T2DM). The aim of the study was to compare oral glucose tolerance test (OGTT) characteristics: time of peak glucose, glucose level ≥155 mg/dL at 1 h, presence of metabolic syndrome (MetS), sensitivity, secretion, and oral disposition index (oDI) in children with and without obesity, according to oral glucose tolerance curve shape: monophasic or biphasic. METHODS: Cross-sectional study including 143 children. Groups were divided into (a) obese: biphasic (B-Ob) (n=55) and monophasic (M-Ob) (n=50), (b) without obesity: biphasic (B-NonOb) (n=20) and monophasic (M-NonOb) (n=18). RESULTS: Late glucose peak was more frequent in the M-Ob group (p<0.001). Glucose levels ≥155 mg/dL and MetS were more frequent in the M-Ob group but did not show significance. The groups with obesity (biphasic and monophasic) had higher indices of insulin resistance and insulin secretion compared to the nonobese groups (biphasic and monophasic) (p<0.001). AUC glucose was higher in the M-Ob group (p<0.05), and AUC insulin was higher in the M-NonOb group. oDI (Matsuda) was significantly lower in the M-Ob group compared to the other groups (p<0.001), and oDI-HOMA IR was higher in M-NonOb group (p=0.03). CONCLUSIONS: All OGTT parameters could help to identify Mexican children at increased risk of developing T2DM, not only fasting plasma glucose and 2 h glucose. M-Ob in non-T2DM Mexican children reflects an early defect in glucose metabolism. Higher level of IR indexes in M-NonOb vs. B-NonOb could indicate an increased risk for T2DM of genetic origin.

METABOLIC DYSFUNCTION-ASSOCIATED STEATOTIC LIVER DISEASE - ASSESSMENT OF PATIENTS WITH OBESITY AND METABOLIC SYNDROME - GUIDELINE FROM THE BRAZILIAN SOCIETY OF BARIATRIC AND METABOLIC SURGERY.

BACKGROUND: Metabolic dysfunction-associated steatotic liver disease (MASLD) is the most prevalent chronic liver disease in the world and was recently renamed to emphasize its metabolic component. AIMS: This article seeks to fill the gap in specific guidelines for patients with obesity and MASLD who will undergo bariatric surgery. METHODS: A systematic search for guidelines was carried out on PubMed and Embase platforms. RESULTS: A total of 544 articles were found, of which 11 were selected according to inclusion and exclusion criteria. All 11 guidelines are from clinical societies; therefore, they do not include some necessary interpretations for bariatric patients. CONCLUSIONS: We recommend that every patient undergoing bariatric and metabolic surgery be screened initially with the Fibrosis-4 (FIB-4) score, followed by transient hepatic elastography (vibration-controlled transient elastography, VCTE), especially for those with FIB-4>1.3. However, interpreting VCTE results in obese patients requires further studies to define the actual cutoff values. Enhanced Liver Fibrosis® shows promise but its availability is limited. The indication for liver biopsy during surgery needs to be individualized but it is recommended for those with changes in FIB-4 and/or VCTE. Family screening is recommended for relatives of young patients with already advanced fibrosis. Liver transplantation is an option for patients with advanced MASLD but the optimal timing for bariatric surgery with transplantation is still unclear. Regular follow-up and VCTE examination are recommended to monitor disease progression after surgery.

Dietary patterns according to gender and ethnicity associated with metabolic syndrome: a systematic review and meta-analysis.

The objective of this systematic review (SR) with meta-analysis (MA) was to identify the dietary patterns of the population, regarding ethnicity and gender, and their association with the metabolic syndrome and its risk factors (MetS-RF). The literature search was performed using Medline, Scopus, Ebsco, SciELO, and BVS databases. Studies with adult participants that identified dietary patterns associated with MetS-RF were included. Pooled odds ratio (OR) and 95%CI were calculated using a random-effect, generic inverse variance method. Statistical heterogeneity and publication bias were explored. The dietary patterns were classified as healthy or unhealthy. Studies were categorized into three groups: Women (all ethnicities), Afro-descendant (men and women), and General Population (both genders and ethnicity). Among the articles found (n=8,496), 22 integrated the SR and 11 the MA. The adherence to the healthy dietary pattern was negatively associated (protective factor) with MetS-RF only in the General Population (OR=0.77; 95%CI: 0.61-0.98). Nevertheless, the unhealthy dietary pattern was associated with the higher prevalence of MetS-RF in all analyzed groups. It was concluded that an unhealthy eating pattern increases the chances of SM-RF in adults, regardless of gender and ethnicity.

Relationship of Mitochondrial DNA Oxidation and Content with Metabolic Syndrome and Cardiovascular Risk in Obesity Phenotypes.

Objective: Obesity, chronic inflammation, and oxidative stress can influence mitochondrial DNA (mtDNA) content. Our objective was to evaluate the oxidation level and content of mtDNA and its relationship with metabolic parameters in metabolically healthy obese (MHO) compared to metabolically unhealthy obese (MUO) and normal weight (NW) controls. Materials and Methods: We studied 94 NW, 95 MHO, and 97 MUO individuals between 18 and 80 years old. Relative mtDNA content and mtDNA oxidation level (8-oxoguanine, 8-OxoG) were determined in peripheral blood leukocytes by the SYBR Green method of real-time PCR. One-way ANOVA and Tukey test were used to compare biochemical, clinical, and anthropometric characteristics, as well as mtDNA content and 8-OxoG. Results: A progressive decrease in mtDNA content was observed between NW, MHO, and MUO with significant differences in MUO vs. NW (p: 0.04). An increase in 8-OxoG was observed in MUO patients compared to the other groups (MUO vs. MHO p: 0.01; MUO vs. NW p: 0.04). mtDNA content was directly correlated with HDL-c (p < 0.01) and inversely with waist circumference (p: 0.01) and LDL-c (p: 0.05). mtDNA content decreased, and the oxidation level increased concomitantly with the presence of obesity, the number of MS components, higher coronary risk, and insulin resistance parameters. Conclusion: MHO presented a similar mtDNA oxidation level to NW and mtDNA content to the MUO, placing the MHO individuals as having an intermediate phenotype. Changes in mtDNA content and oxidation were correlated to the lipid profile related to obesity and/or MS presence, probably associated with oxidative stress and chronic low-grade inflammation.

Liver enzyme levels in adolescents with obesity and insulin resistance: a propensity score matching analysis.

BACKGROUND: Elevated liver enzyme levels have been associated with metabolic syndrome in both obese and non-obese pediatric populations. This study aims to compare the serum liver enzyme levels in obese adolescents with and without insulin resistance (IR). METHODS: A cross-sectional analysis was conducted involving obese adolescents aged 10-18. We assessed somatometry, serum insulin levels, lipid profiles, and liver enzymes (aspartate aminotransferase [AST], alanine aminotransferase [ALT], and gamma-glutamyl transferase [GGT]). Statistical differences between groups were evaluated using Student's t-test or the Chi-squared test, with IR (wIR) status matched by propensity scores based on body mass index (BMI) z-scores. RESULTS: The study included 365 adolescents with obesity, 229 wIR, and 136 without (woIR). Before matching, the wIR group had a significantly higher BMI z-score (2.21 vs. 2.14, p = 0.032). After matching for BMI z-scores (n = 122 each group), the wIR group displayed significantly higher levels of AST (32.3 vs. 24.7, p < 0.001) and ALT (42.4 vs. 30.9, p < 0.001), but no significant differences were observed in GGT levels (37.4 vs. 32.5, p = 0.855). CONCLUSION: Obese adolescent's wIR exhibit higher serum ALT and AST levels, suggesting that altered AST is a potential risk factor for IR.

INTRODUCCIÓN: Se ha observado asociación entre niveles elevados de enzimas hepáticas y síndrome metabólico en población pediátrica con y sin obesidad. El objetivo del estudio fue comparar los niveles séricos de enzimas hepáticas entre adolescentes con obesidad con y sin resistencia a la insulina (RI). MÉTODOS: Se realizó un estudio transversal en adolescentes con obesidad entre 10 y 18 años. Se analizaron los datos somatometricos, insulina sérica, perfil lipídico y niveles de enzimas hepáticas (aspartato aminotransferasa [AST], alanina aminotransferasa [ALT] y gamma-glutamil transferasa [GGT]). Análisis estadístico: se utilizó t de Student o la prueba de Chi-cuadrado para evaluar diferencias entre grupos. Los pacientes con RI se emparejaron con pacientes sin RI utilizando puntuaciones de propensión basadas en la puntuación z del IMC. RESULTADOS: Se incluyeron un total de 365 adolescentes con obesidad (229 con RI y 136 sin RI). El grupo con RI tuvo un IMC mayor (con RI 2.21 vs sin RI 2.14 p = 0.032). Después de emparejar los grupos según el IMCz (n = 122 por grupo), el grupo con RI tuvo niveles de AST (24.7 vs., 32.3, p < 0.001) y ALT (30.9 vs., 42.4, p < 0.001) significativamente más altos en comparación al grupo sin RI. Sin embargo, no hubo diferencia en los niveles de GTT (37.4 vs 32.5, p = 0.855). CONCLUSIONES: Los niveles séricos de ALT y AST en adolescents con obesidad y RI fueron mayores. La AST alterada fue un factor de riesgo para presentar RI.

Salvia elegans Vahl Counteracting Metabolic Syndrome and Depression in Mice on a High-Fat Diet.

Salvia elegans Vahl is a plant commonly used in Mexico as a remedy for nervous disorders, inflammatory diseases, and "ringing in the ears"; the latter can be associated with arteriosclerotic conditions and arterial hypertension. Therefore, based on medicinal use, this work aimed to evaluate the hydroalcoholic extract (SeHA, 100 mg/kg) of this plant and two fractions, ethyl acetate (SeFAc, 50 mg/kg), and obtained from SeFAc fractionation denominated SeF3 (10 mg/kg), on several alterations derived from metabolic syndrome (MetS) derived from the ingestion of a high-calorie diet (high-fat diet), in ICR (Institute of Cancer Research) mice, leading to chronic inflammation that results in neurological damage such as depression. Therefore, several MetS-related parameters, such as forced swim tests, hypertension, serum corticosterone levels, glucose, triglycerides, cholesterol, adiposity index, and insulin resistance, will be evaluated. Additionally, tumor necrosis factor (TNF)-α, interleukin (IL)-1ß, IL-6, and IL-10 levels were measured in kidneys, fat tissue, brains, and spleens. It was proven that all those S. elegans-derived treatments reversed the damage, showing antidepressant, antihypertensive, antihyperglycemic, and antidyslipidemic effects and decreased adiposity, insulin resistance, and serum corticosterone. They induced a modulatory response by modifying the levels of TNF-α, IL-1ß, IL-6, and IL-10 in different organs. High-performance liquid chromatography (HPLC) analysis of the acetate of ethyl fraction from S. elegans (SeFAc) fraction revealed the presence of rosmarinic and caffeic acids as well as flavonoids, while the fraction from SeFAc called SeF3 Was identified by gas mass as methyl glucose, glycerol, and known sterols, among others. Thus, it was concluded that S. elegans protects against the harmful effects of MetS.

[Prevalence of metabolic syndrome in adult patients with obstructive sleep apnea syndrome]. / Prevalencia de síndrome metabólico en pacientes adultos con síndrome de apneas obstructivas del sueño.

Obstructive sleep apnea syndrome (OSAS) is associated with cardiovascular risk factors that comprise metabolic syndrome, including central obesity, hypertension, insulin resistance, impaired glucose tolerance, and dyslipidaemia. AIM: To assess metabolic syndrome prevalence in adult patients with OSAS. METHODS: We administered a standardized clinical questionnaire and four sleep questionnaires (Berlin, Epworth Sleepiness Scale, STOP, and STOP-Bang), and measured anthropometric variables. We also measured serum glucose and lipids, and blood pressure following an overnight fast. Metabolic syndrome was diagnosed according to National Cholesterol Education Program criteria. Patients underwent an overnight ambulatory respiratory polygraphy to confirm the diagnosis of OSAS. The predictive variables were subjected to univariate and multivariate analysis in a logistic regression model. RESULTS: Of 1,030 screened patients, 68% were male, 92% had comorbidities and 58% had moderate-severe OSAS. Subjects with OSAS were more obese, had higher cervical and waist circumference, blood pressure and fasting serum glucose, had lower HDL cholesterol, and an increased incidence of metabolic syndrome (55.4% vs. 44.8%, p<0.013). Age, male sex, hypertension, body mass index, cervical, waist and hip circumferences, intense snoring, witnessed apnea, nocturia, and components of metabolic syndrome were associated with the risk of OSAS and its severity. Fasting blood glucose, blood pressure, and waist circumference were associated with the risk of moderate or severe OSAS, which was not significant for the alteration of blood lipids. CONCLUSION: Patients with OSAS have a high prevalence of metabolic syndrome. OSAS was associated with an increase in the cardiovascular risk factors that comprise the metabolic syndrome.

Effectiveness of DASH Diet versus Other Diet Modalities in Patients with Metabolic Syndrome: A Systematic Review and Meta-Analysis.

BACKGROUND: Metabolic syndrome refers to the coexistence of several known cardiovascular risk factors, including insulin resistance, obesity, atherogenic dyslipidemia, and hypertension. These conditions are interrelated and share underlying mediators, mechanisms, and pathways. Improvement in dietary habits has been shown to improve metabolic parameters in patients undergoing treatment with different diets. METHODS: A systematic search in different databases was realized using the keywords "Metabolic syndrome", "X syndrome", "Dash dietary" and "Dash diet". Finally, six studies were included in this meta-analysis. RESULTS: All articles comparing the DASH diet vs. other diet modalities reported significant differences in favor of the DASH diet on Systolic blood pressure (SBP) (standardized mean difference [SMD] = -8.06, confidence interval [CI] = -9.89 to -7.32, and p < 0.00001), Diastolic blood pressure (SMD = -6.38, CI = -7.62 to -5.14, and p < 0.00001), Cholesterol HDL (SMD = 0.70, CI = 0.53 to 0.88, and p < 0.00001) and Cholesterol LDL (SMD = -1.29, CI = -1.73 to -0.85, and p < 0.00001) scales. CONCLUSIONS: The DASH diet has been shown to be beneficial in altered parameters in patients with MS, and the resulting improvements can significantly affect the daily health of these patients. We therefore recommend that professionals who manage these pathologies promote the use of the DASH diet for the management of specific symptoms.

Prevalence and metabolic risk factors of chronic kidney disease among a Mexican adult population: a cross-sectional study in primary healthcare medical units.

Introduction: The intricate relationship between obesity and chronic kidney disease (CKD) progression underscores a significant public health challenge. Obesity is strongly linked to the onset of several health conditions, including arterial hypertension (AHTN), metabolic syndrome, diabetes, dyslipidemia, and hyperuricemia. Understanding the connection between CKD and obesity is crucial for addressing their complex interplay in public health strategies. Objective: This research aimed to determine the prevalence of CKD in a population with high obesity rates and evaluate the associated metabolic risk factors. Material and Methods: In this cross-sectional study conducted from January 2017 to December 2019 we included 3,901 participants of both sexes aged ≥20 years who were selected from primary healthcare medical units of the Mexican Social Security Institute (IMSS) in Michoacan, Mexico. We measured the participants' weight, height, systolic and diastolic blood pressure, glucose, creatinine, total cholesterol, triglycerides, HDL-c, LDL-c, and uric acid. We estimated the glomerular filtration rate using the Collaborative Chronic Kidney Disease Epidemiology (CKD-EPI) equation. Results: Among the population studied, 50.6% were women and 49.4% were men, with a mean age of 49 years (range: 23-90). The prevalence of CKD was 21.9%. Factors significantly associated with an increased risk of CKD included age ≥60 years (OR = 11.70, 95% CI [9.83-15.93]), overweight (OR = 4.19, 95% CI [2.88-6.11]), obesity (OR = 13.31, 95% CI [11.12-15.93]), abdominal obesity (OR = 9.25, 95% CI [7.13-11.99]), AHTN (OR = 20.63, 95% CI [17.02-25.02]), impaired fasting glucose (IFG) (OR = 2.73, 95% CI [2.31-3.23]), type 2 diabetes (T2D) (OR = 14.30, 95% CI [11.14-18.37]), total cholesterol (TC) ≥200 mg/dL (OR = 6.04, 95% CI [5.11-7.14]), triglycerides (TG) ≥150 mg/dL (OR = 5.63, 95% CI 4.76-6.66), HDL-c <40 mg/dL (OR = 4.458, 95% CI [3.74-5.31]), LDL-c ≥130 mg/dL (OR = 6.06, 95% CI [5.12-7.18]), and serum uric acid levels ≥6 mg/dL in women and ≥7 mg/dL in men (OR = 8.18, 95% CI [6.92-9.68]), (p < 0.0001). These factors independently contribute to the development of CKD. Conclusions: This study underscores the intricate relationship between obesity and CKD, revealing a high prevalence of CKD. Obesity, including overweight, abdominal obesity, AHTN, IFG, T2D, dyslipidemia, and hyperuricemia emerged as significant metabolic risk factors for CKD. Early identification of these risk factors is crucial for effective intervention strategies. Public health policies should integrate both pharmacological and non-pharmacological approaches to address obesity-related conditions and prevent kidney damage directly.

Burden of metabolic syndrome on primary healthcare costs among older adults: A cross-sectional study.

BACKGROUND: The impact of metabolic syndrome (MetS) on healthcare costs remains unclear in the literature. OBJECTIVES: To determine the impact of MetS on primary healthcare costs of adults, as well as to identify the impact of physical activity and other covariates on this phenomenon. DESIGN AND SETTING: This cross-sectional study was conducted in the city of Presidente Prudente, State of São Paulo/Brazil, in 2016. METHODS: The sample comprised 159 older adults (> 50 years) of both sexes (110 women) who were identified from their medical records in the Brazilian National Health Service. Healthcare costs (US$) were assessed through medical records and divided into medical consultations, medications, laboratory tests, and total costs. MetS was assessed using medical records. RESULTS: The Brazilian National Health Service spent more on consultations (US$ 22.75 versus US$ 19.39; + 17.3%) and medication (US$ 19.65 versus US$ 8.32; + 136.1%) among adults with MetS than among those without MetS, but the costs for laboratory tests were similar (P = 0.343). Total costs were 53.9% higher in adults with MetS than in those without the diagnosis of the disease (P = 0.001). Regarding total costs, there was an increase of US$ 38.97 when five components of MetS were present (P = 0.015), representing an increase of approximately 700%, even after adjusting for sex, age, and physical activity. CONCLUSION: In conclusion, the presence of the MetS is responsible for increasing primary care costs among older adults, especially in those related to medicines.

Prediction of metabolic syndrome and its associated risk factors in patients with chronic kidney disease using machine learning techniques.

INTRODUCTION: Chronic kidney disease (CKD) and metabolic syndrome (MS) are recognized as public health problems which are related to overweight and cardiometabolic factors. The aim of this study was to develop a model to predict MS in people with CKD. METHODS: This was a prospective cross-sectional study of patients from a reference center in São Luís, MA, Brazil. The sample included adult volunteers classified according to the presence of mild or severe CKD. For MS tracking, the k-nearest neighbors (KNN) classifier algorithm was used with the following inputs: gender, smoking, neck circumference, and waist-to-hip ratio. Results were considered significant at p < 0.05. RESULTS: A total of 196 adult patients were evaluated with a mean age of 44.73 years, 71.9% female, 69.4% overweight, and 12.24% with CKD. Of the latter, 45.8% had MS, the majority had up to 3 altered metabolic components, and the group with CKD showed statistical significance in: waist circumference, systolic blood pressure, diastolic blood pressure, and fasting blood glucose. The KNN algorithm proved to be a good predictor for MS screening with 79% accuracy and sensitivity and 80% specificity (area under the ROC curve - AUC = 0.79). CONCLUSION: The KNN algorithm can be used as a low-cost screening method to evaluate the presence of MS in people with CKD.

Effects of aerobic exercise on components of the metabolic syndrome in older adults with type 2 diabetes mellitus: systematic review and meta-analysis. / Efectos del ejercicio aeróbico sobre los componentes del síndrome metabólico en adultos mayores con diabetes mellitus tipo 2: revisión sistemática y metaanálisis.

OBJECTIVE.: To determine the effects of aerobic exercise on the components of the metabolic syndrome in older adult diabetic patients by means of a systematic review with meta-analysis. MATERIALS AND METHODS.: We used the PubMed/Medline, Scopus, Cochrane library, Web of Science databases and the Google Scholar search engine. Randomized controlled trials (RCTs) were selected according to the inclusion criteria. Two reviewers independently determined whether studies met the inclusion criteria, extracted data, and used the Cochrane risk of bias tool (RoB 2). Quantitative analyses were performed in R v 4.0.5, using random effects. RESULTS.: We identified 8697 studies, of which 7 RCTs were included in the qualitative synthesis. Most studies were assessed as having a high or low RoB in at least three domains. Meta-analysis showed that aerobic exercise was effective in improving glucose levels (standardized mean difference [SMD]: -1.04; 95% confidence interval [95% CI] -1.27, -0.81), systolic blood pressure (SMD: -0.79; 95% CI: -1.02, -0.56), diastolic blood pressure (SMD: -0.75; 95% CI: -0.98, -0.52), glycosylated hemoglobin (SMD: -0.57, 95% CI: -0.77, -0.37), HDL (SMD: 0.35, 95% CI: 0.15, 0.55), triglycerides (SMD: -0.26, 95% CI: -0.47, -0.06). No significant adverse effects were reported. The level of certainty of the results was low for fasting glucose, moderate for systolic and diastolic blood pressure, and very low for the other outcomes, in addition to few adverse effects. However, these results should be interpreted with caution due to the use of surrogate markers. CONCLUSIONS.: Aerobic exercise was shown to have a significant improvement in the components of the metabolic syndrome in older diabetic adults, and no major adverse effects were reported. However, we recommend more RCTs with longer intervention time to establish the impact on symptoms and complications.Motivation for the study. The motivation for this research arises from the high prevalence of metabolic syndrome and diabetes mellitus around the world. Despite their impact, there is a gap in knowledge regarding non-pharmacological interventions in older adults aimed at improving the metabolic profile of these patients. Main findings. Our results show a significant improvement in glucose, blood pressure, glycosylated hemoglobin, HDL, and triglyceride levels after the aerobic exercise intervention. In addition, no significant adverse effects were observed. Public health implications. Physical exercise is an affordable and globally available strategy. It improves the metabolic profile of older adult patients with metabolic syndrome.

Contributing role of metabolic genes APOE, FTO, and LPL in the development of atrial fibrillation: insights from a case-control study.

OBJECTIVE: The aim of the study was to examine the expression profile of genes (APOE, FTO, and LPL) associated with metabolic syndrome (MetS) in subjects with concomitant atrial fibrillation (AF). METHODS: A total of 690 subjects were categorized into control, AF without MetS, and AF with MetS. RESULTS: The expression profiles of the APOE, FTO, and LPL genes were decreased in AF subjects and AF subjects with MetS as compared to the controls. In AF without the MetS group, an inverse relationship was found between the expression of the LPL gene with body mass index (BMI) and a positive relationship with creatine kinase-MB, whereas expression of the FTO gene was inversely associated with fasting blood glucose and positively with cardiac troponin I in AF suffering from MetS. Expression of the LPL gene was directly linked with systolic blood pressure (SBP) and high-density lipoprotein-cholesterol (HDL-C), whereas an inverse correlation with heart rate and expression of the FTO gene in AF with MetS were shown. The expression of the LPL gene was inversely related to BMI in subjects with AF. The expression of the LPL gene was positively correlated with SBP and HDL-C and negatively correlated with heart rate, while the expression of the FTO gene was an important predictor of AF with MetS. CONCLUSION: The decreased expression of APOE, FTO, and LPL genes in AF with and without MetS indicates their potential contributing role in the pathogenesis of AF.

In vitro evaluation of multifunctional peptides PW, PF, PPG, PM, IW, and SW for metabolic syndrome management.

Multifunctional peptides derived from various food sources, including ancestral grains, hold significant promise for managing metabolic syndrome. These bioactive peptides exhibit diverse properties that collectively contribute to improving the components of metabolic syndrome. In this study, we investigated the in vitro multifunctionality of six peptides (PW, PM, SW, PPG, PW, and IW) identified through in silico analysis and chemically synthesized. These peptides were evaluated for their potential to address metabolic syndrome-related activities such as antidiabetic, antiobesity, antihypertensive, and antioxidative properties. Assessment included their capacity to inhibit key enzymes associated with these activities, as well as their free radical scavenging and cellular antioxidative activities. Principal component analysis was employed to cluster the peptides according to their multifunctionality. Our results revealed that peptides containing tryptophan (SW, PW, and IW) exhibited the most promising multifunctional attributes, with SW showing particularly high potential. This multifunctional peptide represents a promising avenue for addressing metabolic syndrome.

The Beneficial Effects of Prenatal Biotin Supplementation in a Rat Model of Intrauterine Caloric Restriction to Prevent Cardiometabolic Risk in Adult Female Offspring.

Numerous studies indicate that intrauterine growth restriction (IUGR) can predispose individuals to metabolic syndrome (MetS) in adulthood. Several reports have demonstrated that pharmacological concentrations of biotin have therapeutic effects on MetS. The present study investigated the beneficial effects of prenatal biotin supplementation in a rat model of intrauterine caloric restriction to prevent cardiometabolic risk in adult female offspring fed fructose after weaning. Female rats were exposed to a control (C) diet or global caloric restriction (20%) (GCR), with biotin (GCRB) supplementation (2 mg/kg) during pregnancy. Female offspring were exposed to 20% fructose (F) in drinking water for 16 weeks after weaning (C, C/F, GCR/F, and GCRB/F). The study assessed various metabolic parameters including Lee's index, body weight, feed conversion ratio, caloric intake, glucose tolerance, insulin resistance, lipid profile, hepatic triglycerides, blood pressure, and arterial vasoconstriction. Results showed that GCR and GCRB dams had reduced weights compared to C dams. Offspring of GCRB/F and GCR/F dams had lower body weight and Lee's index than C/F offspring. Maternal biotin supplementation in the GCRB/F group significantly mitigated the adverse effects of fructose intake, including hypertriglyceridemia, hypercholesterolemia, hepatic steatosis, glucose and insulin resistance, hypertension, and arterial hyperresponsiveness. This study concludes that prenatal biotin supplementation can protect against cardiometabolic risk in adult female offspring exposed to postnatal fructose, highlighting its potential therapeutic benefits.

Asprosin levels in patients with type 2 diabetes mellitus, metabolic syndrome and obesity: A systematic review and meta-analysis.

BACKGROUND & AIMS: Asprosin is a promising candidate for novel treatments for metabolic-endocrine disorders. The objective of this systematic review and meta-analysis was to consolidate the existing evidence regarding asprosin levels in patients diagnosed with type 2 diabetes (T2D), metabolic syndrome (MetS), and obesity. METHODS: Scopus, Embase, PubMed, Ovid/Medline, and Web of Science were systematically searched without restrictions. We only used the standardized mean differences (SMD) with their 95 % confidence intervals (95 % CI) as the effect measure. A random-effects model (DerSimonian and Laird method) was used for the meta-analysis. Risk of bias was assessed with the Newcastle-Ottawa Scale and Newcastle-Ottawa Scale for Cross-Sectional Studies. RESULTS: Twenty-six studies (n = 3,787) were included in the meta-analysis. Participants with T2D had higher asprosin values than those without T2D (SMD: 1.64; 95 % CI: 1.08-2.21; I2 = 97 %). Patients with MetS had higher asprosin levels compared to those without MetS (SMD: 0.99; 95 % CI: 0.34-1.64; I2 = 96 %). Patients with obesity had higher asprosin levels than participants without obesity (SMD: 1.49; 95 % CI: 0.23-2.76; I2 = 98 %). CONCLUSIONS: Asprosin is significantly higher in patients with either T2D, MetS, or obesity, compared with controls.

Heterogeneous Pathological Changes in Liver Lobes During Liver Disease: A Perspective Review.

Liver diseases have a global prevalence of 25%, accounting for 4% of all deaths worldwide, and are associated with a 36% increased risk of fatal and nonfatal cardiovascular events. Metabolic dysfunction-associated steatotic liver disease constitutes the liver expression of metabolic syndrome and represents the primary type of liver disease. Microscopical analysis of biopsies, which allows the evaluation of a small portion of tissue with inferences made to the entire organ, is considered the gold standard for determining the presence of liver diseases. However, potential sampling errors in liver biopsies are conceivable because the obtained tissue represents only a tiny fraction of the entire liver mass and may not accurately reflect the true pathological state. Studies have demonstrated the existence of sampling errors in liver biopsies, particularly concerning the severity of inflammation, degree of fibrosis, and the presence of cirrhosis. Also, clinical studies have shown that histopathological abnormalities are better detected in humans when liver samples are collected from both the right and the left lobes. However, a gap exists in clinical investigation to clarify the role of differences between these lobes in improving the diagnostic and prognostic for liver diseases. Building upon the heterogeneous nature of pathological alterations observed in liver lobes, this perspective review provided recommendations to enhance the precision of diagnosis and prognostic accuracy of liver diseases.

Environmental Enrichment Prevents Gut Dysbiosis Progression and Enhances Glucose Metabolism in High-Fat Diet-Induced Obese Mice.

Obesity is a global health concern implicated in numerous chronic degenerative diseases, including type 2 diabetes, dyslipidemia, and neurodegenerative disorders. It is characterized by chronic low-grade inflammation, gut microbiota dysbiosis, insulin resistance, glucose intolerance, and lipid metabolism disturbances. Here, we investigated the therapeutic potential of environmental enrichment (EE) to prevent the progression of gut dysbiosis in mice with high-fat diet (HFD)-induced metabolic syndrome. C57BL/6 male mice with obesity and metabolic syndrome, continuously fed with an HFD, were exposed to EE. We analyzed the gut microbiota of the mice by sequencing the 16s rRNA gene at different intervals, including on day 0 and 12 and 24 weeks after EE exposure. Fasting glucose levels, glucose tolerance, insulin resistance, food intake, weight gain, lipid profile, hepatic steatosis, and inflammatory mediators were evaluated in serum, adipose tissue, and the colon. We demonstrate that EE intervention prevents the progression of HFD-induced dysbiosis, reducing taxa associated with metabolic syndrome (Tepidimicrobium, Acidaminobacteraceae, and Fusibacter) while promoting those linked to healthy physiology (Syntrophococcus sucrumutans, Dehalobacterium, Prevotella, and Butyricimonas). Furthermore, EE enhances intestinal barrier integrity, increases mucin-producing goblet cell population, and upregulates Muc2 expression in the colon. These alterations correlate with reduced systemic lipopolysaccharide levels and attenuated colon inflammation, resulting in normalized glucose metabolism, diminished adipose tissue inflammation, reduced liver steatosis, improved lipid profiles, and a significant reduction in body weight gain despite mice's continued HFD consumption. Our findings highlight EE as a promising anti-inflammatory strategy for managing obesity-related metabolic dysregulation and suggest its potential in developing probiotics targeting EE-modulated microbial taxa.
