Prevalence Of Metabolic Syndrome Research Articles

Metabolic syndrome in children and adolescents

Background: Metabolic syndrome is a serious condition associated with multiple diseases. The prevalence of metabolic syndrome is increasing caused by an increase in obesity rates among children and adolescents.Current Concepts: Owing to the various definitions used, there is lack of consensus regarding the diagnostic criteria for metabolic syndrome in children and adolescents. Although the exact pathogenesis remains unclear, insulin resistance and subsequent inflammation are key mechanistic contributors. Metabolic syndrome is characterized by overweight and obesity accompanied by abnormalities in glucose metabolism, dyslipidemia, and hypertension and is associated with other conditions such as fatty liver, polycystic ovary syndrome, and a pro-inflammatory state. Prevention and management of metabolic syndrome can be achieved through lifestyle modifications, behavioral interventions, pharmacotherapy, and surgical interventions.Discussion and Conclusion: Childhood and adolescent obesity serves as a risk factor for metabolic syndrome during later life. Early identification and intervention are important to prevent the progression of metabolic syndrome. Clinicians must identify at-risk children and adolescents and provide guidance for the prevention and management of metabolic syndrome.

Association of severity of menstrual dysfunction with cardiometabolic risk markers among women with polycystic ovary syndrome.

Polycystic ovary syndrome (PCOS) is associated with a wide range of unfavorable cardiometabolic risk factors, including obesity, hypertension, insulin resistance, impaired glucose metabolism, dyslipidemia, and metabolic syndrome. Compared with women with regular menstrual cycles, women with a history of irregular menstrual periods have an increased unfavorable cardiometabolic risk. Recently, the association between the severity of oligomenorrhea and hyperinsulinemia and insulin resistance has been demonstrated. However, evidence linking the severity of menstrual cyclicity with cardiometabolic risk in PCOS women is scarce. This work was a prospective cross-sectional study. A total of 154 women diagnosed with PCOS by the Rotterdam criteria were recruited from July 2021 to September 2022. PCOS women with eumenorrheic (eumeno group), oligomenorrhea (oligo group), and amenorrhea (ameno group) underwent history and physical examination, gonadal steroid hormone measurement, lipid profile, oral glucose tolerance test, and homeostasis model assessment of insulin resistance. A trend toward an increase in unfavorable cardiometabolic risk markers including obesity, hypertension, prevalence of insulin resistance, prediabetes, dyslipidemia, and metabolic syndrome was observed in the ameno group (n = 57) as compared with the eumeno (n = 24) or oligo group (n = 73). A higher prevalence of insulin resistance (odds ratio [OR]: 3.02; 95% confidence interval [CI]: 1.03-8.81) and prediabetes (OR: 3.94; 95% CI: 1.01-15.40) was observed in the ameno group than in the eumeno group, and a higher proportion of dyslipidemia (OR: 2.44; 95% CI: 1.16-5.15) was observed in the ameno group than in the oligo group in the binary logistic regression analysis after adjusting for confounding factors. PCOS women with amenorrhea show a higher prevalence of insulin resistance, prediabetes, and dyslipidemia compared with those with oligomenorrhea or eumenorrhea. The severity of menstrual dysfunction could be used as a readily obtainable marker for the identification of PCOS women at greatest risk of cardiometabolic diseases.

Prevalence of metabolic syndrome in non functional adrenal incidentaloma: a case-control study

Prevalence of metabolic syndrome in non functional adrenal incidentaloma: a case-control study

The impact of lifestyle, measured with the HLPCQ questionnaire on the prevalence of metabolic syndrome in Poland: a multicenter study

Metabolic syndrome is one of the most common health problems for people around the world. The aim of our study was to assess the prevalence of metabolic syndrome among adults without prior diagnosis of cardiovascular disease, diabetes, and chronic kidney disease. We also plan to assess the influence of certain lifestyle components on prevalence of metabolic syndrome. The study involved cardiovascularly healthy patients undergoing lab tests, measurements, and the HLPCQ questionnaire (The Healthy Lifestyle and Personal Control Questionnaire). The data were used to diagnose metabolic syndrome. Out of 1044 patients from 10 primary care facilities, 23.3% met the metabolic syndrome criteria, showing a strong link with increased blood pressure, cholesterol, and fasting glucose. Lower scores in the Organized physical exercise subscale of the HLPCQ questionnaire were noted in those with metabolic syndrome. Comparing the subscale of HLPCQ questionnaire, the lower results in Organized physical exercise subscale were found among the participants with metabolic syndrome, both male and females. Metabolic syndrome, a significant risk factor for cardiovascular disease, should be screened for actively, even in apparently healthy populations. Results obtained in our study from analysis of HLPCQ show that screening for metabolic syndrome should be preceded by prevention based on regular physical activity and proper eating habits.

Prevalence of metabolic syndrome among patients with hepatocellular carcinoma of different etiologies: a retrospective study.

This study compared the prevalences of metabolic syndrome and of cardiac or kidney comorbidities among patients with hepatocellular carcinoma (HCC) associated with metabolic dysfunction-related fatty liver disease (MAFLD), chronic infection with hepatitis B or C virus (HBV or HCV), or the combination of MAFLD and chronic HBV infection. Medical records were retrospectively analyzed for patients with HCC who underwent hepatectomy between March 2013 and March 2023. Patients with HCC of different etiologies were compared in terms of their clinicodemographic characteristics and laboratory data before surgery. Of the 2422 patients, 1,822 (75.2%) were chronically infected with HBV without MAFLD and HCV, 415 (17.2%) had concurrent MAFLD and chronic HBV infection but no HCV infection, 121 (5.0%) had MAFLD without hepatitis virus infection, and 64 (2.6%) were chronically infected with HCV in the presence or absence of MAFLD and HBV infection. Compared to patients chronically infected with HBV without MAFLD and HCV, those with MAFLD but no hepatitis virus infection showed significantly lower prevalence of cirrhosis, ascites, portal hypertension, alpha-fetoprotein concentration ≥ 400 ng/mL, tumor size > 5cm, multinodular tumors and microvascular invasion. Conversely, they showed significantly higher prevalence of metabolic syndrome, hypertension, type 2 diabetes, abdominal obesity, history of cardiovascular disease, T-wave alterations, hypertriglyceridemia and hyperuricemia, as well as higher risk of arteriosclerotic cardiovascular disease. Compared to patients with MAFLD but no hepatitis virus infection, those with concurrent MAFLD and chronic infection with HBV showed significantly higher prevalence of cirrhosis, ascites and portal hypertension, but significantly lower prevalence of hypertension and history of cardiovascular disease. Compared to patients with other etiologies, those chronically infected with HCV in the presence or absence of MAFLD and HBV infection, showed significantly higher prevalence of cirrhosis, portal hypertension, ascites, and esophagogastric varices. Patients with HCC associated with MAFLD tend to have a background of less severe liver disease than those with HCC of other etiologies, but they may be more likely to suffer metabolic syndrome or comorbidities affecting the heart or kidneys.

Estudio del índice de gravedad del síndrome metabólico como factor predictivo de un episodio cardiovascular mayor en mujeres premenopáusicas con lupus eritematoso sistémico

BackgroundPatients with systemic lupus erythematosus (SLE) have an increased risk of metabolic syndrome (MS) and cardiovascular (CV) disease. MS is evaluated binary, limiting the understanding of each component's severity individually. Therefore, severity scores for MS that evaluate them separately have been developed. This study aims to determine the prognosis between MS severity and the occurrence of major adverse cardiovascular events (MACE) in SLE patients. MethodsTen-year follow-up cohort study. Premenopausal>18-year-old women with a previous diagnosis of SLE were included. Patients with recent CV events, pregnancy, thyroid disease, and liposuction were excluded. The variables of interest were CV events; the confounding variables, and the MS severity indexes were examined. Hazard ratios and Kaplan-Meier survival curves were estimated through Cox regression. ResultsA total of 238 women were analyzed: 22 presented MACE, and 216 did not. MS prevalence, measured according to consensus and ATP-III criteria, was higher in MACE patients (50 and 40,95%, respectively). The MetSx-IMC severity index was higher within the MACE group. Cox analysis showed an increase in the MetSx-IMC associated with the risk of suffering MACE in a 1.107 ratio. ConclusionsThe MetSx-IMC severity index, contrary to the binary approaches, is recommended to evaluate MS as a predictor of MACE in SLE patients. Offering improved and more accurate prognosis in patients at risk of developing MCE.

Associations between Hysterectomy and Metabolic Syndrome: The Multi-Ethnic Study of Atherosclerosis

Metabolic syndrome is linked to an increased risk of incident cardiovascular disease (CVD) and all-cause mortality. Notable associations exist between hysterectomy with bilateral salpingo-oophorectomy and metabolic syndrome. However, there is emerging evidence that even with ovarian conservation, hysterectomy may be independently associated with long-term CVD risk. To examine the associations between hysterectomy with ovarian preservation and metabolic syndrome risk in a multi-ethnic cohort. We studied 3,367 female participants in the Multi-Ethnic Study of Atherosclerosis who had data on self-reported history of hysterectomy, oophorectomy, hystero-oophorectomy and metabolic syndrome at baseline (2000-2002). We used adjusted logistic regression to assess the cross-sectional associations between hysterectomy/oophorectomy subgroups and prevalent metabolic syndrome at baseline. Furthermore, we investigated 1,355 participants free of baseline metabolic syndrome and used adjusted Cox regression models to evaluate incident metabolic syndrome from exams 2 (2002-2004) to 6 (2016-2018). The mean±SD age was 59.0±9.5 years, with 42% White, 27% Black, 19% Hispanic, and 13% Chinese American participants. 29% and 22% had a history of hysterectomy and oophorectomy, respectively. Over a median follow-up period of 10.5 (3.01-17.62) years, there were 750 metabolic syndrome events. Hysterectomy [HR, 1.32 (95%CI, 1.01-1.73)] and hystero-oophorectomy [1.40 (1.13-1.74)] were both strongly associated with incident metabolic syndrome compared to having neither hysterectomy or oophorectomy. Hysterectomy, even with ovarian preservation, may be independently associated with a higher risk of metabolic syndrome. If other studies confirm these findings, screening and preventive strategies focused on females with ovary-sparing hysterectomy and the mechanisms underpinning these associations may be explored.

Obesity and metabolic syndrome in patients with heart failure with preserved ejection fraction: a cross-sectional analysis of the Veradigm Cardiology Registry.

The proportion of heart failure patients with preserved ejection fraction has been rising over the past decades and has coincided with increases in the prevalence of obesity and metabolic syndrome. The relationship between these interconnected comorbidities and heart failure with preserved ejection fraction (HFpEF) is still poorly understood. This study characterized obesity and metabolic syndrome among real-world patients with HFpEF. We identified adults with heart failure in the Veradigm Cardiology Registry, previously the PINNACLE Registry, with a left ventricular ejection fraction measurement ≥ 50% between 01/01/2016 and 12/31/2019. Patients were stratified by obesity diagnosis and presence of metabolic syndrome (≥ 3 of the following: diabetes, hypertension, hyperlipidemia, and obesity). We captured baseline demographic and clinical characteristics and used multivariable logistic regression to examine the odds of having cardiac (atrial fibrillation, coronary artery disease, coronary artery bypass surgery, myocardial infarction, and stroke/transient ischemic attack) and non-cardiac (chronic kidney disease, chronic liver disease, and peripheral artery disease) comorbidities of interest. The models adjusted for age and sex, and the main covariates of interest were obesity and metabolic burden score (0-3 based on the presence of diabetes, hypertension, and hyperlipidemia). The models were run with and without an obesity*metabolic burden score interaction term. This study included 264,571 patients with HFpEF, of whom 55.7% had obesity, 52.5% had metabolic syndrome, 42.5% had both, and 34.3% had neither. After adjusting for age, sex, and burden of other metabolic syndrome-associated diagnoses, patients with HFpEF with obesity had lower odds of a diagnosis of other evaluated comorbidities relative to patients without obesity. The presence of metabolic syndrome in HFpEF appears to increase comorbidity burden as each additional metabolic syndrome-associated diagnosis was associated with higher odds of assessed comorbidities except atrial fibrillation. Obesity was common among patients with HFpEF and not always co-occurring with metabolic syndrome. Multivariable analysis suggested that patients with obesity may develop HFpEF in the absence of other driving factors such as cardiovascular disease or metabolic syndrome.

A Cross-Sectional Study to Evaluate the Prevalence of Metabolic Syndrome in Pre-Menopausal and Post-Menopausal Women

A Cross-Sectional Study to Evaluate the Prevalence of Metabolic Syndrome in Pre-Menopausal and Post-Menopausal Women

IT’S ALL IN THE ACTION

CASE SETTING The prevalence of metabolic syndrome in patients with serious mental illness is almost double the prevalence reported for the general population of Australia. Cardiometabolic disease and mental illness are overrepresented in adult prison populations, with people in custody significantly more likely to have cardiovascular disease and Type 2 diabetes. The Forensic Hospital, is a mental health facility with 140 beds that sits within Justice Health NSW. It is specifically designed for people who have mental illness and have been involved with the criminal justice system, as well as those who are considered to be at high risk in the community. The Ministry of Health and Justice Health NSW have several documents that make reference to the importance of screening for Metabolic Syndrome however barriers exist at the patient, staff, and organisational level to implementing the recommended physical health guidelines in a high secure forensic mental health setting. TREATMENT It’s All In The Action is a Quality Improvement project led by the Forensic Hospital’s Senior Exercise Physiologist and Rehabilitation Coordinator. The initiative focused on embedding physical health intervention for Forensic Hospital patients at risk of or diagnosed with metabolic syndrome through the establishment of the Metabolic Care Team. RESULTS A defined physical health pathway to intervention within the Forensic Hospital in the form of a physical health MDT, atypical in the Forensic Mental Health setting. REFLECTIONS/LEARNINGS The presentation will outline the steps taken in a ground up approach to address the growing concern of systemic neglect and achieve service level change. It will demonstrate translation of best practice research as well as State and National policy and guidelines into tangible action for a significantly marginalised population group. Finally, it will reflect on the sustainability of this initiative, the integration of partnerships, and recommendations for prospective next steps.

Common Comorbidities in Patients with Remitting Seronegative and Symmetrical Synovitis with Pitting Edema (RS3PE).

Remitting seronegative symmetrical synovitis with pitting edema (RS3PE) is considered a rare inflammatory rheumatologic disorder that is seen primarily in older adult men. Patients present with arthralgias of large joints accompanied by painful pitting edema of the hands and feet. Few studies have reported the prevalence of metabolic syndromes, including diabetes mellitus and hyperlipidemia in these patients. This case series reviewed 25 patients who were diagnosed as having RS3PE in a private outpatient clinic. Nearly half of the patients (48%) had diabetes mellitus, predominantly type 2, and more than half of the patients (60%) had hyperlipidemia. We believe that future case studies on RS3PE should include an assessment of various comorbidities that can be seen in patients with this autoinflammatory disorder. The increased availability of musculoskeletal ultrasound provides a potential area of study to differentiate this disorder from other inflammatory arthritis and improve reaching the correct diagnosis.

The literature review highlights the escalating prevalence of metabolic syndrome as an urgent medical and social concern among children and adolescents, primarily attributed to the global epidemic of childhood obesity. The article not only outlines key findings but also presents recommendations from international medical societies concerning screening strategies, diagnostics, and therapeutic approaches for the individual components contributing to metabolic syndrome in childhood. The review also focuses on pivotal studies exploring alternative therapies targeting the principal pathogenic factors of the disease. In conclusion, the authors emphasize the pressing issue of the absence of standardized criteria for diagnosing metabolic syndrome in children, highlighting the imperative role of a multidisciplinary team of specialists in the effective management of this pathology in pediatric practice.

EXPLORING THE RELATIONSHIP BETWEEN PHYSICAL ACTIVITY AND METABOLIC SYNDROME RISK IN YOUNG ADULTS: A REVIEW

Metabolic syndrome is a cluster of interrelated risk factors that increase the risk of cardiovascular disease and type 2 diabetes, particularly among young adults. Physical activity has been identified as a key lifestyle factor that can help mitigate the risk of developing metabolic syndrome. This review aims to synthesize the current evidence on the association between physical activity and metabolic syndrome risk in young adults. The review discusses the prevalence of metabolic syndrome in young adults and the various mechanisms by which physical activity can influence metabolic syndrome risk, including improvements in body composition, insulin sensitivity, lipid profile, and blood pressure regulation. Several studies have demonstrated that higher levels of physical activity, especially moderate-to-vigorous intensity exercise, are associated with a lower risk of metabolic syndrome in young adult populations. However, the relationship between physical activity and metabolic syndrome risk may be moderated by factors such as sex and socioeconomic status. The review also highlights the need for further research to better understand the long-term impact of physical activity, the optimal types and intensities of exercise, and the development of tailored interventions to promote sustained physical activity and improve metabolic health in young adults. In conclusion, this review emphasizes the importance of encouraging and supporting young adults to engage in regular physical activity as a strategy for the prevention and management of metabolic syndrome. Promoting physically active lifestyles among this population should be a public health priority to address the growing burden of metabolic syndrome and its associated health consequences.

Association between the severity of hard-to-treat psoriasis and the prevalence of metabolic syndrome: A hospital-based cross-sectional study in Jakarta, Indonesia.

Psoriatic lesions on the scalp, face, intertriginous, genitals, palms/soles, and nails are often delay diagnosed, hard-to-treat, and cause disability. Metabolic syndrome (MetS) is one of the most frequent and significant comorbidities in psoriasis. Many studies have discovered a link between psoriasis and MetS, but none have specifically assessed the hard-to-treat psoriasis in Indonesian population. This is a multicenter study involving four dermatology referral hospitals to investigate the association between psoriasis severity that has hard-to-treat lesions with the prevalence of MetS in Jakarta, Indonesia. Data was collected from April to October 2022. The severity of 84 hard-to-treat psoriasis patients was measured by Psoriasis Area Severity Index (PASI) scores. The participants divided into PASI score >10 (severe) and ≤ 10 (mild-moderate) groups. MetS was identified based on the modified National Cholesterol Education Program Adult Treatment Panel III. MetS was found in 64.3% of patients. Patients with a PASI score>10 had a significantly higher risk of metabolic syndrome compared to those with a score ≤ 10 (78.6% vs 50%, OR 3.667; 95% CI 1.413-9.514; p = 0.006). The prevalence of hypertension (p = 0.028), low levels of high-density lipoprotein (HDL) cholesterol (p = 0.01), mean fasting blood sugar (p = 0.018), and triglyceride levels (p = 0.044) between the two groups differed significantly. This study found most frequent components of MetS were abdominal obesity, decreased levels of HDL cholesterol, hypertension, hyperglycemia, and hypertriglyceridemia respectively. Individuals with severe hard-to-treat psoriasis had a 3.67 times more likely to have MetS rather than the mild-moderate group.

Patients with Celiac Disease Have High Prevalence of Fatty Liver and Metabolic Syndrome.

In recent years, patients with celiac disease (CeD) have been reported to have a high prevalence of fatty liver and metabolic syndrome. We conducted a systematic review and meta-analysis to assess the prevalence of fatty liver and metabolic syndrome in patients with CeD and effect of gluten-free diet in them. The PubMed, Embase and the Cochrane Library databases were searched for original studies upto November 18, 2022. We included full-text articles published in the English language after 1990 that used well-defined criteria for CeD, fatty liver and metabolic syndrome. A random effects model was used to calculate pooled prevalence. Of 350 studies identified, 11 studies (n = 2578) were included in the analysis. On analysis of both cross-sectional and longitudinal studies, pooled prevalence of fatty liver and metabolic syndrome in treatment-naïve patients with CeD were 18.2% (95% CI 8.3-30.8%, n = 1237) and 4.3% (95% CI 2.4-6.7, n = 1239) and in those on GFD of varying duration was 28.2% (95% CI 20.7-36.4%, n = 1368) and 21.3% (95% CI 11.7-32.9%, n = 2193), respectively. There was no difference in the prevalence of fatty liver and metabolic syndrome between low- or high-income group countries. Patients with CeD have a high prevalence of fatty liver and metabolic syndrome which increases further with the initiation of GFD. Patients with CeD should thus be screened and monitored for development of fatty liver and metabolic syndrome. They should be counselled appropriately regarding their diet and inclusion of physical activity in their lifestyle.

Changes in the Prevalence of Metabolic Syndrome before and after the COVID-19 Pandemic According to Household Income Levels.

Since the World Health Organization's pandemic declaration in March 2020, Korea has witnessed shifts in lifestyle behaviors, impacting habits tied to socioeconomic status and contributing to metabolic syndrome (MetS). To investigate this issue, the current study aimed to investigate changes in MetS prevalence, particularly based on income levels before and after the coronavirus disease 2019 (COVID-19) pandemic. This study used data from the 8th Korea National Health and Nutrition Examination Survey (2019-2020). A total of 6,840 individuals aged 30-65 years were included in this study. Household income was divided into high (≥75th percentile), middle (25-75th percentile), and low (≤25th percentile). A multivariable logistic regression analysis was performed to explore the interaction between this association before and after the COVID-19 pandemic. A statistically significant difference was found in the prevalence of MetS before and after the COVID-19 pandemic (26.7% to 30.2%, P=0.001). These changes differed based on income levels. The increase in the prevalence of MetS was statistically significant in the low- and high-income groups but not in the middle-income group (low: 8.0%p increase [P=0.039], middle: 1.0%p increase [P=0.522], high: 6.4%p increase [P<0.001]). The interaction between household income and the COVID-19 pandemic on MetS was statistically significant (P for interaction= 0.032). This study revealed that P for interaction between household income, MetS, and the period before and after the COVID-19 pandemic was significant. Changes in physical activity and eating habits during the COVID- 19 pandemic may have contributed to these differences.

Prevalence of metabolic syndrome and associated factors among patient with type 2 diabetes mellitus in Ethiopia, 2023: asystematic review and meta analysis

BackgroundMetabolic syndrome is a complex pathophysiologic state which characterized by abdominal obesity, insulin resistance, hypertension, and hyperlipidaemia. The Adult Treatment Panel III report (ATP III) of the National Cholesterol Education Programme identified the metabolic syndrome as a serious public health issue in the modern era. In Western and Asian nations, the frequency of metabolic syndrome is rising, especially in developing regions experiencing rapid socio-environmental changes, in Sub-Saharan Africa; metabolic syndrome may be present in more than 70% of people with type 2 diabetes mellitus. Therefore the objective of our study was to estimate the pooled prevalence of metabolic syndrome and associated factors among type II diabetes mellitus patient.MethodThis systematic review and meta-analysis included original articles of cross sectional studies published in the English language. Searches were carried out in PubMed, Web of Science, Google Scholar, and grey literature Journals from 2013 to June 2023. A random-effects model was used to estimate the pooled prevalence of metabolic syndrome among type II Diabetes mellitus patient in Ethiopia. Heterogeneity was assessed using the I2 statistic. Subgroup analysis was also conducted based on study area. Egger’s test was used to assess publication bias. Sensitivity analysis was also conducted.ResultsOut of 300 potential articles, 8 cross sectional studies were included in this systematic review and meta-analysis study. The pooled prevalence of metabolic syndrome among patient with type II diabetes mellitus in Ethiopia was found to be 64.49% (95% CI: 62.39, 66.59) and 52.38% (95% CI: 50.05, 54.73) by using NCEP/ATP III and IDF criteria, respectively. The weighted pooled prevalence of metabolic syndrome among type II diabetes mellitus patients by sub group analysis based on the study region was 63.79% (95% CI: 56.48, 71.11) and 52.23% (95%CI: 47.37, 57.22) by using NCEP/ATP III and IDF criteria, respectively. Being female and increased body mass index were factors associated with metabolic syndrome among type II diabetes mellitus patients.ConclusionThe prevalence of metabolic syndrome among type II patient is high. Therefore, policymakers, clinicians, and concerned stakeholders shall urge effective strategies in the control, prevention, and management of metabolic syndrome among type II diabetes mellitus.

The Global Prevalence of Metabolic Syndrome in Connection with Sleep Duration: A Systematic Review and Meta-Analysis.

The duration and quality of sleep are believed to significantly influence the onset of metabolic syndrome (MetS), but existing data lack consistency. The meta-analysis aims to evaluate the prevalence of the MetS in association with sleep duration. We conducted a systematic review according to the Preferred Reporting Items for Systematic Reviews and Meta-analyses 2020 guidelines. A comprehensive search of PubMed, Google Scholar, and Research Gate databases was performed to identify cohort and cross-sectional studies published in English between 2013 and 2023. We included studies that examined the association between sleep duration/quality and MetS, and two independent reviewers assessed study quality and bias using the Newcastle-Ottawa scale. The systematic review included 11 studies with a total of 343,669 participants, including 4 cohort studies and 7 cross-sectional studies. Sample sizes varied widely, ranging from 293 to 162,121 individuals. The studies had different follow-up periods, participant ages ranging from 10 to 80 years, and predominantly male populations. The prevalence of MetS was higher in average sleepers [52%, 95% confidence interval (CI): 40%-64%] compared with short sleepers (13%, 95% CI: 8%-18%) and long sleepers (15%, 95% CI: 9%-24%). Globally, North American countries exhibit the highest prevalence of MetS across short- (25.3%, 95% CI: 4.2%-72.4%) and long-sleeper (22.4%, 95% CI: 2.8%-74.1%) categories, whereas Asian countries experience the highest prevalence among the average sleeper category (58.7%, 95% CI: 44.1%-71.9%). Our meta-analysis indicates an elevated prevalence of MetS in average sleepers. Future research endeavors address delve into the underlying mechanisms and incorporate objective measures to understand the multifaceted connection between sleep patterns and MetS, guiding more effective preventive and management strategies.

Prognostic Factors after Hepatectomy for Hepatocellular Carcinoma—The Importance of Pathological Immunophenotyping, the Steatohepatitic Subtype and the Impact of the Hepatic Pedicle Clamping

Introduction: Hepatectomy (HP) is, along with liver transplantation, the only potentially curative treatment for Hepatocellular Carcinoma (HCC). The high prevalence of Metabolic Syndrome (MS) may be causing a shift in the HCC spectrum. Hepatic Pedicle Clamping (HPC), used to reduce perioperative bleeding during HP, has been theorized to increase the risk of recurrence. Cytokeratin 19 (CK19) and glypican-3 (GLP-3) have been identified as markers of worse prognosis in HCC. Materials and Methods: A clinical and pathological review of 59 patients undergoing HP for HCC between 2005 and 2013 was performed. Chronic liver disease was observed in 53 patients (89.8%), with cirrhosis in 54.2% [most frequent etiologies: ethylism (47.5%), HCV (25.4%) and HBV (11.9%)]. MS was in 36% of patients. In addition, 95% of patients had Child–Pugh class A and 5% class B, and there was a median MELD of 8 (6–18). A single nodule was observed in 46 patients (78%) with an average size of 5.4 cm. Microscopic vascular invasion (MiVI) was in 49% of patients and macroscopic (MaVI) in 17. HPC was in 43 patients (74.1%). Statistical analysis was performed with SPSS™ 21.0. Survival tests (Kaplan–Meier, log-rank and Cox regression). Statistical significance was with p &lt; 0.05. Results: Major morbidity in 22% of patients. Mortality in 5.1%. Median overall survival (OS) of 71 months and median disease-free survival (DFS) of 37. In a multivariate analysis: MaVI (p = 0.001), MiVI (p = 0.005) and HCV infection (p = 0.002) were associated with worse OS; MS was associated with better OS (p = 0.001); MaVI (p = 0.000), MiVI (p = 0.035) and HPC (p = 0.012) were associated with worse DFS. CK19+/GLP-3− (p = 0.007) and CK19−/GLP-3+ (p = 0.029) patients were associated with worse DFS and CK19−/GLP-3− (p = 0.031) with better DFS. Discussion/Conclusions: HPC was an independent factor of worse DFS. The ischemia-reperfusion injury (IRI) produced by HPC could promote a more angiogenic and angioinvasive phenotype of tumor cells, resulting in higher recurrence. HCV etiology was associated with worse OS. MS was associated with better OS, highlighting the importance of a hepatectomy in these cases. The combined detection of CK19 and GLP-3 was an independent prognostic factor in HCC patients allowing for the identification of more aggressive tumors.

The Effect of Diesel Exhaust Particles on Adipose Tissue Mitochondrial Function and Inflammatory Status.

Air pollution poses a significant global health risk, with fine particulate matter (PM2.5) such as diesel exhaust particles (DEPs) being of particular concern due to their potential to drive systemic toxicities through bloodstream infiltration. The association between PM2.5 exposure and an increased prevalence of metabolic disorders, including obesity, metabolic syndrome, and type 2 diabetes mellitus (T2DM), is evident against a backdrop of rising global obesity and poor metabolic health. This paper examines the role of adipose tissue in mediating the effects of PM2.5 on metabolic health. Adipose tissue, beyond its energy storage function, is responsive to inhaled noxious stimuli, thus disrupting metabolic homeostasis and responding to particulate exposure with pro-inflammatory cytokine release, contributing to systemic inflammation. The purpose of this study was to characterize the metabolic response of adipose tissue in mice exposed to either DEPs or room air (RA), exploring both the adipokine profile and mitochondrial bioenergetics. In addition to a slight change in fat mass and a robust shift in adipocyte hypertrophy in the DEP-exposed animals, we found significant changes in adipose mitochondrial bioenergetics. Furthermore, the DEP-exposed animals had a significantly higher expression of adipose inflammatory markers compared with the adipose from RA-exposed mice. Despite the nearly exclusive focus on dietary factors in an effort to better understand metabolic health, these results highlight the novel role of environmental factors that may contribute to the growing global burden of poor metabolic health.
