RESUMO

Growing evidences showed that heavy metals exposure may be associated with metabolic diseases. Nevertheless, the mechanism underlying arsenic (As) exposure and metabolic syndrome (MetS) risk has not been fully elucidated. So we aimed to prospectively investigate the role of serum uric acid (SUA) on the association between blood As exposure and incident MetS. A sample of 1045 older participants in a community in China was analyzed. We determined As at baseline and SUA concentration at follow-up in the Yiwu Elderly Cohort. MetS events were defined according to the criteria of the International Diabetes Federation (IDF). Generalized linear model with log-binominal regression model was applied to estimate the association of As with incident MetS. To investigate the role of SUA in the association between As and MetS, a mediation analysis was conducted. In the fully adjusted log-binominal model, per interquartile range increment of As, the risk of MetS increased 1.25-fold. Compared with the lowest quartile of As, the adjusted relative risk (RR) of MetS in the highest quartile was 1.42 (95% confidence interval, CI: 1.03, 2.00). Additionally, blood As was positively associated with SUA, while SUA had significant association with MetS risk. Further mediation analysis demonstrated that the association of As and MetS risk was mediated by SUA, with the proportion of 15.7%. Our study found higher As was remarkably associated with the elevated risk of MetS in the Chinese older adults population. Mediation analysis indicated that SUA might be a mediator in the association between As exposure and MetS.

RESUMO

Hábitos alimentares inadequados, sedentarismo e a maior expectativa de vida da população contribuem significativamente para a prevalência da síndrome metabólica. Essa doença predispõe uma pessoa a desenvolver diabetes mellitus tipo 2 e doenças cardiovasculares, as quais têm um amplo impacto na saúde pública, induzindo sobrecarga no sistema de saúde e reduzindo a qualidade de vida dos indivíduos afetados. A síndrome metabólica é uma doença multifatorial e está relacionada ao processo de envelhecimento, contudo, ainda há uma lacuna significativa, em termos de estudos, sobre a prevalência da condição em populações idosas. Nesse contexto, o presente estudo objetivou rastrear a prevalência da síndrome metabólica em participantes da Universidade Aberta da Terceira Idade (UNATI), localizada em Francisco Beltrão, Paraná. Os critérios diagnósticos de síndrome metabólica abordados nesta pesquisa incluem: circunferência abdominal ≥ 90 cm para homens e ≥ 80 cm para mulheres, triglicerídeos ≥ 150 mg/dL, HDL ≤ 40 mg/dL para homens e ≤ 50 mg/dL para mulheres, pressão arterial sistólica ≥ 130 mmHg e/ou pressão arterial diastólica ≥ 85 mmHg ou estar em farmacoterapia para hipertensão, além de glicemia de jejum ≥ 100 mg/dL ou estar em tratamento farmacológico para diabetes. Um total de 44 idosos foram avaliados, apresentando uma média de idade de 66,9 ± 7,1 anos, com uma predominância de mulheres (88%). Os resultados revelaram uma prevalência alarmante de síndrome metabólica, atingindo 36,4% da amostra estudada. Além disso, observou-se uma alta prevalência de condições associadas, como hipertensão arterial (67,2%), sobrepeso (58,6%) e obesidade visceral (31%). Esses achados ressaltam a importância da implementação de medidas preventivas direcionadas à promoção da qualidade de vida saudável e ao controle dos fatores de risco metabólicos.


Inadequate dietary habits, sedentary lifestyle, and increased life expectancy significantly contribute to the prevalence of metabolic syndrome. This condition predisposes an individual to develop type 2 diabetes mellitus and cardiovascular diseases, which have a broad impact on public health, inducing a burden on the healthcare system and reducing the quality of life of affected individuals. Metabolic syndrome is a multifactorial disease and is related to the aging process; however, there is still a significant gap in terms of studies on the prevalence of the condition in elderly populations. In this context, this study aimed to screen the prevalence of metabolic syndrome in participants of the Open University for the Third Age (UNATI), located in Francisco Beltrão, Paraná. The diagnostic criteria for metabolic syndrome addressed in this research include: abdominal circumference ≥ 90 cm for men and ≥ 80 cm for women, triglycerides ≥ 150 mg/dL, HDL ≤ 40 mg/dL for men and ≤ 50 mg/dL for women, systolic blood pressure ≥ 130 mmHg and/or diastolic blood pressure ≥ 85 mmHg or being on pharmacotherapy for hypertension, in addition to fasting glucose ≥ 100 mg/dL or being on pharmacological treatment for diabetes. A total of 44 elderly individuals were evaluated, with a mean age of 66.9 ± 7.1 years, predominantly women (88%). The results revealed an alarming prevalence of metabolic syndrome, affecting 36.4% of the studied sample. Furthermore, a high prevalence of associated conditions was observed, such as arterial hypertension (67.2%), overweight (58.6%), and visceral obesity (31%). These findings underscore the importance of implementing preventive measures aimed at promoting healthy lifestyles and controlling metabolic risk factors.

Introduction: Nonalcoholic fatty liver disease is one of the main causes of liver disease. Cytokeratin 18 emerges as a non-invasive marker for the assessment of liver fibrosis. The objective of the work was to validate the use of cytokeratin 18 in peripheral blood in the diagnosis and evolution of patients with non-alcoholic fatty liver disease. Methodology: To validate cytokeratin 18 in the diagnosis, a case-control study was carried out. The case group was patients over 18 years of age, of both sexes, with a diagnosis of non-alcoholic fatty liver disease linked to metabolic syndrome, recruited between 2/2/2019 to 2/2/2020. The control group were blood donors. They were matched 1-1 for age and sex. Cytokeratin 18 was quantified in peripheral blood of both groups. To validate cytokeratin 18 in the evolution of patients with non-alcoholic fatty liver disease, a prospective, longitudinal study was carried out. The group of patients recruited were followed for one year under standard treatment, at the end of which cytokeratin 18 was quantified in peripheral blood. Continuous variables are expressed with the mean and standard deviation. It was analyzed with Student's t test, α error < 5%. Results: 13 patients make up the case group (12 women), 53 ± 11 years old, with BMI 35.01 ± 8.9 kg/m2. The pre-treatment cytokeratin 18 value was 1410 ± 120 IU, and the post-treatment value was 117 ± 56, p < 0.005. The control group was 13 people (12 women), 43.4 ± 8.1 years and BMI 28.10 ± 5.4 kg/m2 The cytokeratin 18 value was 193 ± 7.2 IU, p < 0.005 vs. pretreatment case group. Conclusions: Cytokeratin 18 is higher in patients with non-alcoholic fatty liver disease, being statistically significant, and decreases with treatment with statistical significance, and may become a useful marker in this group of patients.

RESUMO

INTRODUCTION/OBJECTIVES: Changes in the stool metabolome have been poorly studied in the metabolic syndrome (MetS). Moreover, few studies have explored the relationship of stool metabolites with circulating metabolites. Here, we investigated the associations between stool and blood metabolites, the MetS and systemic inflammation. METHODS: We analyzed data from 1,370 participants of the KORA FF4 study (Germany). Metabolites were measured by Metabolon, Inc. (untargeted) in stool, and using the AbsoluteIDQ® p180 kit (targeted) in blood. Multiple linear regression models, adjusted for dietary pattern, age, sex, physical activity, smoking status and alcohol intake, were used to estimate the associations of metabolites with the MetS, its components and high-sensitivity C-reactive protein (hsCRP) levels. Partial correlation and Multi-Omics Factor Analysis (MOFA) were used to investigate the relationship between stool and blood metabolites. RESULTS: The MetS was significantly associated with 170 stool and 82 blood metabolites. The MetS components with the highest number of associations were triglyceride levels (stool) and HDL levels (blood). Additionally, 107 and 27 MetS-associated metabolites (in stool and blood, respectively) showed significant associations with hsCRP levels. We found low partial correlation coefficients between stool and blood metabolites. MOFA did not detect shared variation across the two datasets. CONCLUSIONS: The MetS, particularly dyslipidemia, is associated with multiple stool and blood metabolites that are also associated with systemic inflammation. Further studies are necessary to validate our findings and to characterize metabolic alterations in the MetS. Although our analyses point to weak correlations between stool and blood metabolites, additional studies using integrative approaches are warranted.

RESUMO

Serum triglyceride concentrations increase in dogs with obesity, which is typically assessed by body condition score (BCS), however little is known about changes that take place in non-obese dogs in overweight condition. Further, the associations of triglyceride levels with other markers of energy homeostasis are poorly characterised in healthy animals. The present study aimed to evaluate associations between both BCS and triglyceride concentrations with other markers of lipid and glucose metabolism in healthy, non-obese dogs, as well as to assess whether these markers change significantly in non-obese dogs with overweight as compared to their lean counterparts. Serum concentrations of cholesterol, free fatty acids, triglycerides, insulin, glucose and fructosamine were measured in 532 healthy, client-owned dogs, assigned either to 'lean' (BCS: 3-5) or 'overweight' (BCS: 6-7) categories. Generalised linear mixed models were used to assess associations between BCS categories, triglyceride concentrations and other variables, correcting for the effect of breed. Compared with lean dogs, overweight dogs had a greater serum cholesterol concentration (95% CI, 5.3-6.2 mmol/L or 205-237 mg/dL versus 5.1-5.4 mmol/L or 198-210 mg/dL, p = 0.0032), insulin concentration (95% CI, 17.5-22.1 µU/ml versus 16.7-18.0 µU/ml, p = 0.0374) and were older (95% CI, 4.0-5.3 versus 3.4-3.7 years, p = 0.0005). Triglyceride concentrations were positively associated with fructosamine (r 2 = 0.31, p = 0.0012), cholesterol (r 2 = 0.25, p < 0.0001), insulin (r 2 = 0.14, p = 0.0030) and glucose (r 2 = 0.10, p = 0.0014) concentrations, and negatively associated with free fatty acid concentrations (r 2 = 0.11, p < 0.0001). However, there was no association between triglyceride concentrations and age. In conclusion, both BCS and triglyceride concentrations were associated with other markers of glucose and lipid metabolism in non-obese healthy dogs, amongst which those with overweight showed metabolic changes as compared to their lean counterparts. Triglyceride concentrations were associated with an increase in insulin and fructosamine concentrations that might reflect an early-phase impairment in glucose tolerance which, surprisingly, was concurrent with lower basal free fatty acid concentrations.

RESUMO

Background Metabolic syndrome (MetS) represents a critical public health challenge globally, characterized by a cluster of metabolic abnormalities that heighten the risk of cardiovascular diseases and type 2 diabetes. In India, the prevalence of MetS, particularly in urban areas, is rising rapidly. This study investigates the prevalence of MetS and its association with waist circumference in middle-aged individuals from urban Mumbai. Methods A cross-sectional study was conducted among 1,851 participants (814 men and 1,037 women, with a mean age of 56.8 years) in a public health camp in urban Mumbai. Data were collected on anthropometric measures, blood pressure, and blood markers, including fasting glucose and lipid profiles. MetS was diagnosed based on the National Cholesterol Education Program Adult Treatment Panel III (NCEP ATP III) criteria. This included the presence of three or more of the following five criteria: waist circumference of ≥102 cm for men and ≥88 cm for women, fasting triglycerides of ≥150 mg/dL, fasting high-density lipoprotein (HDL) cholesterol of <40 mg/dL for men and <50 mg/dL for women, blood pressure of ≥130/85 mm Hg, and fasting glucose of ≥100 mg/dL. Data were analyzed using SPSS Statistics version 23 (IBM SPSS Statistics, Armonk, NY). Statistical analyses were performed using the chi-square test, with statistical significance set at p<0.05. Results The overall prevalence of metabolic syndrome (MetS) in the cohort was 32.6% (605 out of 1,851 participants), with women exhibiting a significantly higher prevalence at 38% (394 out of 1,037 women) compared to men at 26% (211 out of 814 men) (p<0.001). High waist circumference (≥102 cm for men and ≥88 cm for women) was strongly correlated with MetS, as 73.8% of individuals (314 out of 425 participants) in the high waist circumference group met the criteria for MetS, compared to 20.4% of individuals (291 out of 1,426 participants) in the non-high waist circumference group (<102 cm for men and <88 cm for women) (p<0.001). Furthermore, elevated blood pressure, elevated fasting glucose, and elevated fasting triglycerides were significantly more common in the high waist circumference group, than in the non-high waist circumference group (p<0.001). Conclusion The study highlights the significant association between central obesity and MetS in an urban Indian population, with notably higher prevalence in women. Waist circumference is a critical determinant of MetS and should routinely be measured, with significant application especially in resource-limited settings for early detection and intervention.

RESUMO

OBJECTIVES: Second-generation antipsychotics (SGAs) are often prescribed for patients with schizophrenia; however, SGAs are associated with the risk of metabolic syndrome (MetS). This study aimed to investigate the clinical and biochemical determinants of SGA-related MetS. METHODS: Patients with schizophrenia, aged between 20 and 65 years, and under clozapine or olanzapine treatment for at least 9 months, were recruited from a mental hospital. Demographic, comorbidity, clinical status, laboratory, and drug regimen data were collected through chart review. Circulating levels of adiponectin, thyroid hormone responsive protein, and fatty acid binding protein 4 (FABP4) were assayed. Multiple logistic regression was used to identify risk predictors of MetS. RESULTS: A total of 176 participants were enrolled, including 138 (78.4 %) clozapine users and 38 (21.6 %) olanzapine users. Forty-five (25.6 %) patients were classified as having MetS. The duration of clozapine or olanzapine usage was significantly shorter in those with MetS (p=0.026) than those without MetS. Patients with MetS had a significantly higher serum FABP4 concentration than their counterparts (22.5 ± 8.8 ng/mL vs. 15.7 ± 6.7 ng/mL, p<0.001), and also a significantly lower adiponectin level (6.9 ±4.0 mg/mL vs. 11.6 ± 6.6 mg/mL, p<0.001). A FABP4 level ≥ 16.98 ng/mL (OR: 24.16, 95 % CI: 7.47-78.09, p<0.001) was positively correlated with MetS, whereas serum adiponectin level was inversely correlated with MetS (OR: 0.7980, 95 % CI: 0.70-0.90, p<0.001). CONCLUSIONS: Adiponectin, FABP4, and certain clinical covariates and comedications were highly correlated with SGA-related MetS. Further studies are required to investigate the underlying mechanisms.

RESUMO

OBJECTIVES: To compare the characteristics of body compositions between metabolic syndrome (MetS) and frailty, and determine the independent and overlapping of MetS and frailty with postoperative complications among older patients with gastric cancer. DESIGN: A prospectively observational study. SETTING AND PARTICIPANTS: Two hundred and eighty six older patients from 60 to 80 years undergoing radical gastrectomy for the first time. MEASUREMENTS: MetS was diagnosed by the criteria from the 2020 edition of Chinese guideline for the prevention and treatment of type 2 diabetes mellitus, and frailty was defined by frailty phenotype. An InBody770 impedance analyzer was used to measure body compositions and with 10 fat- and muscle-related indicators being included in this study. Based on the presence of frailty and MetS, patients were divided into the frailty group, MetS group, frailty+MetS group, and normal group, and the body compositions indicators of these groups were compared. Clavien-Dindo classification was used to grade the severity of postoperative complications. Univariate and multivariate regression models were performed to explore the independent and joint association of MetS and frailty with postoperative complications. RESULTS: The incidence rate of MetS, frailty, and frailty+MetS being 20.3%, 15.7%, and 4.2% respectively. Compared with the normal group, both fat and muscle compositions were decreased significantly in the frailty group (p < 0.05), while the statistically significant difference of fat-to-muscle mass ratio (FMR) and skeletal muscle mass to visceral fat area ratio (SVR) were not observed (p > 0.05). In contrast, except SVR, the other indicators of the MetS group were higher than the normal group (p < 0.05). As to the frailty+MetS group, there was a significant increase in fat compositions and FMR, as well as a significant decline in SVR (p < 0.05), while the difference of muscle compositions was not statistically significant (p > 0.05). There was an association of frailty with postoperative total (OR = 3.068, 95% CI: 1.402-6.713) and severe (OR = 9.423, 95% CI: 2.725-32.589) complications, but no association was found of MetS alone. MetS coexisting with frailty was associated with the highest risk of both total (OR = 3.852, 95% CI: 1.020-14.539) and severe (OR = 12.096, 95% CI: 2.183-67.024) complications. CONCLUSIONS: Both frailty and MetS coexisting with frailty had adverse effects on postoperative complications, which appeared greatly different characteristics in body compositions and therefore reinforced the importance of targeted nutritional or metabolic intervention. Although MetS alone were not significantly associated with postoperative complications, it is essential to focus on the causal relationship and development trend between MetS and frailty to prevent MetS from shifting into frailty, considering the highest risk in their coexistence state.

RESUMO

The glucokinase enzyme (belongs to the hexokinase family) is present in liver cells and ß-cells of the pancreas. Glucokinase acts as a catalyst in the conversion of glucose-6-phosphate from glucose which is rate-limiting step in glucose metabolism. Glucokinase becomes malfunctional or remains inactivated in diabetes. Glucokinase activators are compounds that bind at the allosteric site of the glucokinase enzyme and activate it. This article highlights the patent and recent research papers history with possible SAR from year 2014-2023. The data comprises the discussion of novel chemotypes (GKAs) that are being targeted for drug development and entered into clinical trials. GK activators have attracted massive interest since successful results have been reported from clinical trials data.

RESUMO

Type 2 diabetes mellitus (T2DM) is a multifactorial disease that cannot be linked to a single pathway, causing the observed heterogeneity among T2DM patients. Despite this level of heterogeneity, T2DM is majorly managed by metformin (MET) monotherapy. However, recent findings have associated long-term metformin intake with progressive oxidative pancreatic ß cell damage as the disease progresses. Hence, a significant number of patients treated with MET need an alternate therapy. Hence, identifying drug combinations that can effectively alleviate different diabetes complications would serve as a more promising therapy that can translate into active use. Hence, this study was designed to explore the possible synergistic effect of vitamin D and metformin on T2DM-induced testicular dysfunction. Thirty healthy male Wistar rats (weight: 120-150 g and age: 10 ± 2 weeks) were randomly divided into control, diabetes untreated (HFD+STZ), diabetes + vitamin D (1000 IU/kg), diabetes + metformin (180 mg/kg), and diabetes + vitamin D + metformin. All treatments lasted for 28 days and animals were sacrificed using IP injection of ketamine and xylaxine (40 and 4 mg/kg respectively). Vitamin D improved the ameliorative effect of metformin on T2DM-induced hyperglycemia and lipid dysmetabolism, accompanied by a significant decrease in testicular lactate dehydrogenase and lactate. Also, vitamin D + metformin significantly increased serum luteinizing hormone, follicle-stimulating hormone, testosterone, and testicular 5α reductase activities. Furthermore, vitamin D improved the anti-inflammatory and antioxidant effects of metformin by significantly decreasing T2DM-induced increase in testicular interleukin 1beta, interleukin 6, TNF-α, nitric oxide, and NF-κB and increasing T2DM-induced decrease in interleukin 10, glutathione, superoxide dismutase, catalase, GPx, and Nrf2. Vitamin D enhanced the ameliorative effect of metformin on T2DM-induced testicular dysfunction.

RESUMO

BACKGROUND AND AIMS: Currently, the influence of metabolic syndrome (Mets) on the plaque characteristics and prognosis of patients with acute coronary syndrome (ACS) is poorly understood. Thus, the study aimed to characterize the pancoronay plaques of ACS patients with Mets using optical coherence tomography (OCT) and to evaluate the cohort's prognosis. METHODS: Between February 2015 and September 2020, 745 ACS patients who underwent OCT imaging of the three coronary arteries were included, divided into Mets (n = 252) and non-Mets (n = 493) groups. The major adverse cardiovascular event (MACE) was a composite of cardiac death, non-fatal myocardial infarction (MI), and revascularization. RESULTS: Compared to the non-Mets group, the Mets group exhibited a higher proportion of females and cases of multivessel disease. In the Mets group, culprit lesions were found to have a greater degree of stenosis, thinner fibrous cap thickness and more thin-cap fibroatheroma (TCFA). Additionally, nonculprit lesions were more likely to exhibit plaque rupture, high-risk plaque characteristics, TCFA, macrophage infiltration, cholesterol crystals, and layered plaque. After a median follow-up of 2 years, 8.3% of patients experienced MACE, a rate that was higher in the Mets group, primarily attributed to non-fatal myocardial infarction and cardiac death. Multivariate analysis showed that Mets (aHR 1.73, p = 0.037), high-risk plaque (aHR 2.63, p < 0.001), age (aHR 1.03, p = 0.020), and left ventricular ejection fraction (aHR 0.96, p = 0.002) were independent predictors of MACE. CONCLUSIONS: The presence of Mets increased the vulnerability of the entire coronary tree and worsened the prognosis for patients with ACS.

RESUMO

Intermittent hypoxia in sleep apnea syndrome (SAS) patients increases the oxidative stress and can cause serious cardiovascular diseases such as hypertension or atherosclerotic diseases through endothelial dysfunction. The evaluation of risk caused by oxidative stress, however, is not easy in a clinical setting. Thus, we intended to evaluate the changes in oxidative stress by SAS treatment using a simple method that can be easily used in the clinical testing. We enrolled 42 consecutive newly diagnosed severe SAS patients (30 men). Reactive oxygen species metabolites (d-ROMs) for oxidative stress and biological antioxidant (BAP) in blood samples were estimated using FREE Carrio Duo® before and 3 months after continuous positive airway pressure (CPAP) treatment. SAS parameters were obtained by polysomnography before CPAP and endothelial function was measured twice as well. The body mass index and apnea hypopnea index (AHI) were 29.1 ± 5.3 and 57.9 ± 19.7/h. The d-ROMs and BAP were 317.4 ± 71.8 CARR U and 2121.2 ± 299.6 µmol/L. Although no significant correlation was found between hypoxia parameters and d-ROMs or BAP before CPAP treatment, we found a significant negative correlation between basal AHI or basal oxygen desaturation index representing intermittent hypoxia and the change in d-ROMs (r = - 0.31, p = 0.046/r = - 0.33, p = 0.03) and between the change in SpO2 < 90% duration (min) representing continuous hypoxia and the change in BAP (r = - 0.35, p = 0.03) after CPAP treatment. The changes in d-ROM and BAP might reflect the different kind of reduction of oxidative stress by CPAP treatment and, thus, can be used as handy indicators of the treatment effect.

RESUMO

Background and Aim: Psoriasis is a prevalent chronic inflammatory skin condition, and the Mediterranean diet is often recommended for its health benefits, particularly its ability to mitigate chronic inflammation. This study sought to examine the extent to which psoriasis patients adhere to the Mediterranean diet and to explore its correlation with the severity of their condition. Methods: Seventy-one psoriasis patients and 71 age- and sex-matched healthy controls were enrolled the study and filled a standard questionnaire of adherence to the Mediterranean diet. The relationship between disease severity and adherence to the diet was also dealt with. Results: The Mediterranean diet adherence score in the psoriasis group (5.25 ± 1.64) was significantly lower than the control group (6.28 ± 2.10) (p = 0.004). In addition, the consumption of fruit and fish in psoriasis patients was significantly lower than the control group and the consumption of red meat was significantly higher in the patient group. No significant relationship was found between the severity of the disease and the score of adherence to the Mediterranean diet (p = 0.42). Conclusion: A significant difference between the two groups of psoriasis and the control group following the Mediterranean diet might be indicative of the relationship between diet and psoriasis and the potential benefits of this type of diet due to its anti-inflammatory properties.

RESUMO

BACKGROUND: Adolescent violence victimisation is associated with a spectrum of adult social and behavioural health outcomes, including adverse mental health symptoms. However, underlying social stress mechanisms linking adolescent victimisation to adult cardiometabolic health remains poorly understood. AIM: The current study aims to reveal how adolescent and adult interpersonal violence exposures each get "under the skin" to affect adult metabolic syndrome, including direct victimisation and, additionally, witnessing violence. SUBJECTS AND METHODS: We use a nationally representative longitudinal cohort, the National Longitudinal Study of Adolescent to Adult Health, and leverage a quasi-experimental approach, propensity score matching regression analysis (n = 14,267). RESULTS: We find that adolescent violence exposure carries an enduring effect on young adult metabolic syndrome risk factor incidence and high-risk status, which is independent of young adult violence. Violence effects do not vary by sex or racial identity. CONCLUSION: In sum, adolescent exposure to direct interpersonal violence significantly affects young adult cardiometabolic health in ways suggesting adolescence is a sensitive period for the onset of harmful cardiometabolic effects in early adulthood. Findings warrant future study of underlying pathways and how these effects shape social inequities in cardiometabolic health among U.S. adults broadly.

RESUMO

Obesity and diabetes are known to negatively affect vitamin C status. However, whether the presence of diabetes, in addition to obesity, contributes an additional impact on vitamin C status is currently uncertain. In a cohort of 152 adults living with obesity, we assessed metabolic and nutrient parameters in participants without diabetes (n = 92), and with prediabetes (n = 22) and type 2 diabetes mellitus (T2DM; n = 35). Vitamin C concentrations were measured in plasma and leukocytes using HPLC and vitamin C intakes were assessed using 24-hour dietary recall. Metabolic severity scores were derived using gender, ethnicity, height, weight, waist circumference, systolic blood pressure, fasting glucose, HDL, and triglyceride values. In people living with obesity, those with prediabetes and T2DM had increased metabolic dysregulation and decreased vitamin C status relative to those without diabetes (P < .05). Vitamin C deficiency was observed in a high proportion (23%-32%) of participants with prediabetes and T2DM and ≥50% had hypovitaminosis C. However, there was no difference in vitamin C intake between those without diabetes and those with prediabetes or T2DM (P > .05). There was a significant inverse correlation between plasma vitamin C status and metabolic severity score (r = -0.290, P < .001). Linear regression indicated that for every 1-unit increase in metabolic severity score, there was a 6.5 µmol/L decrease in vitamin C status. Thus, the enhanced metabolic dysregulation observed with prediabetes and T2DM is associated with an increased demand for vitamin C in people living with obesity.

RESUMO

OBJECTIVE: To investigate the influence of adiponectin (APN) rs2241766 and rs1501299 polymorphisms on adiponectin levels and their association with metabolic syndrome (MetS). METHODS: Analyzed two polymorphisms (rs2241766 and rs1501299) of the adiponectin gene (ADIPOQ) in 210 MetS patients and 102 control patients using the polymerase chain reaction-restriction fragment length polymorphism method and DNA sequencing technology. RESULTS: The genotypes of the rs2241766 T/G and rs1501299 G/T polymorphism were significantly associated with serum APN levels in MetS patients. The ADIPOQ polymorphisms were associated with a risk of MetS when compared with that in healthy controls. TG and GG genotypes of rs2241766 were associated with a significantly elevated risk of MetS as compared with the TT genotype (OR = 1.32 and OR = 2.53). Subjects with the G allele appeared to have higher susceptibility to MetS than those with the T allele (OR = 2.21). In common with the findings for rs2241766, the rs1501299 GT and TT genotypes were associated with a significantly increased risk of MetS as compared with the GG genotype (OR = 1.51 and OR = 2.24). The susceptibility to MetS appeared to be higher in subjects with the T allele than in those with the G allele (OR = 1.88). CONCLUSIONS: The occurrence of MetS may be associated with genetic variations at the rs2241766 and rs1501299 loci, especially in individuals with T to G mutations (rs2241766) and G to T mutations (rs1501299). These mutations may lead to decreased APN levels and a higher risk of developing MetS.

RESUMO

AIM: Metabolic comorbidities such as obesity type 2 diabetes, insulin resistance, glucose intolerance, dyslipidemia are the major contributors for lower life expectancy and reduced patient compliance during antipsychotic therapy in patients with severe mental illnesses such as schizophrenia, bipolar disorder, and depression. TRPM8 activation by menthol is also reported to alleviate high fat diet-induced obesity in mice. Additionally, this TRPM8 activation leads to increase in gene expression of thermogenic genes in white adipocytes and dietary menthol was found to increase browning of WAT along with improved glucose utilization. Therefore, we aimed to evaluate the plausible role of TRPM8 channels in olanzapine-induced metabolic alterations in female balb/c mice. METHODS: 6 weeks olanzapine (6 mg kg-1, per oral) model was used in female balb/c mice. Pharmacological manipulation of TRPM8 channel was done using menthol and N-(3-aminopropyl)-2-[(3-methylphenyl)methoxy]-N-(2-thienylmethyl)-benzamide (AMTB), the agonist and antagonist respectively. KEY RESULTS: Menthol co-treatment for six weeks prevented olanzapine-induced metabolic alterations such as weight gain, increased food intake, decreased energy expenditure, adiposity, liver lipid accumulation, systemic inflammation and insulin resistance. Although no significant change in TRPM8 mRNA expression was found in the hypothalamus, however, some of the protective effects of menthol were absent in presence of AMTB indicating possible involvement of TRPM8 channels. CONCLUSION: Our results suggest possible therapeutic implications of menthol in the management of antipsychotic-induced weight gain and other metabolic alterations.

RESUMO

BACKGROUND & AIMS: Body shape expressed as the trunk-to-leg volume ratio is associated with diabetes and mortality due to the associations between higher adiposity and lower lean mass with Metabolic Syndrome (MetS) risk. Reduced appendicular muscle mass is associated with malnutrition risk and age-related frailty, and is a risk factor for poor treatment outcomes related to MetS and other clinical conditions (e.g.; cancer). These measures are traditionally assessed by dual-energy X-ray absorptiometry (DXA), which can be difficult to access in clinical settings. The Shape Up! Adults trial (SUA) demonstrated the accuracy and precision of 3-dimensional optical imaging (3DO) for body composition as compared to DXA and other criterion measures. Here we assessed whether trunk-to-leg volume estimates derived from 3DO are associated with MetS risk in a similar way as when measured by DXA. We further explored if estimations of appendicular lean mass (ALM) could be made using 3DO to further improve the accessibility of measuring this important frailty and disease risk factor. METHODS: SUA recruited participants across sex, age (18-40, 40-60, >60 years), BMI (under, normal, overweight, obese), and race/ethnicity (non-Hispanic [NH] Black, NH White, Hispanic, Asian, Native Hawaiian/Pacific Islander) categories. Each participant had whole-body DXA and 3DO scans, and measures of cardiovascular health. The 3DO measures of trunk and leg volumes were calibrated to DXA to express equivalent trunk-to-leg volume ratios. We expressed each blood measure and overall MetS risk in quartile gradations of trunk-to-leg volume previously defined by National Health and Nutrition Examination Survey (NHANES). Finally, we utilized 3DO measures to estimate DXA ALM using ten-fold cross-validation of the entire dataset. RESULTS: Participants were 502 (273 female) adults, mean age = 46.0 ± 16.5y, BMI = 27.6 ± 7.1 kg/m2 and a mean DXA trunk-to-leg volume ratio of 1.47 ± 0.22 (females: 1.43 ± 0.23; males: 1.52 ± 0.20). After adjustments for age and sex, each standard deviation increase in trunk-to-leg volume by 3DO was associated with a 3.3 (95% odds ratio [OR] = 2.4-4.2) times greater risk of MetS, with individuals in the highest quartile of trunk-to-leg at 27.4 (95% CI: 9.0-53.1) times greater risk of MetS compared to the lowest quartile. Risks of elevated blood biomarkers as related to high 3DO trunk-to-leg volume ratios were similar to previously published comparisons using DXA trunk-to-leg volume ratios. Estimated ALM by 3DO was correlated to DXA (r2 = 0.96, root mean square error = 1.5 kg) using ten-fold cross-validation. CONCLUSION: Using thresholds of trunk-to-leg associated with MetS developed on a sample of US-representative adults, trunk-to-leg ratio by 3DO after adjustments for offsets showed significant associations to blood parameters and MetS risk. 3DO scans provide a precise and accurate estimation of ALM across the range of body sizes included in the study sample. The development of these additional measures improves the clinical utility of 3DO for the assessment of MetS risk as well as the identification of low muscle mass associated with poor cardiometabolic and functional health.

RESUMO

Depression and metabolic syndrome could exacerbate the risks of the other, leading to a series of severe coexisting conditions. One notable comorbidity that must be mentioned is obstructive sleep apnea (OSA). Current studies suggested that depression increases susceptibility to OSA. As the prevalence of depression rises, it becomes critical to prevent and manage its complications or comorbidities, including OSA. Predictive models, non-invasive electroencephalogram monitoring, genetic research, and other promising technologies are being applied to the prevention, diagnosis, and personalized treatment of depression and OSA.
