Background: Metabolic syndrome (MetS) is a complex clinical condition characterized by the coexistence of interrelated metabolic abnormalities that significantly increase the risk of cardiovascular diseases and type 2 diabetes mellitus. Endocan—an endothelial cell-specific molecule—is considered a biomarker of endothelial dysfunction and inflammation. This study aimed to evaluate the relationship between serum endocan levels and the severity of MetS, assessed using the MetS-Z score. Methods: This study included 120 patients with MetS and 50 healthy controls. MetS was diagnosed according to the NCEP-ATP III criteria. MetS-Z scores were calculated using the MetS Severity Calculator. Serum levels of endocan, sICAM-1, and sVCAM-1 were measured using the ELISA method. Results: Serum levels of endocan, sICAM-1, and sVCAM-1 were significantly higher in the MetS group compared to the control group (all p < 0.001). When the MetS group was divided into tertiles based on MetS-Z scores, stepwise and statistically significant increases were observed in the levels of endocan and other endothelial markers from the lowest to highest tertile (p < 0.0001). Correlation analysis revealed a strong positive association between the MetS-Z score and serum endocan levels (r = 0.584, p < 0.0001). ROC curve analysis showed that endocan has high diagnostic accuracy for identifying MetS (AUC = 0.967, p = 0.0001), with a cutoff value of >88.0 ng/L. Conclusions: Circulating levels of endocan were significantly increased in MetS and were associated with the severity of MetS, suggesting that endocan may play a role in the cellular response to endothelial dysfunction-related injury in patients with MetS.

Background/Objectives: Diagnosis of Persistent Spinal Pain Syndrome Type 2 (PSPS-T2) currently lacks objective biomarkers. Therefore, this retrospective study aimed to investigate differences in glucose metabolism in the axial musculoskeletal system in PSPS-T2 patients by means of [¹⁸F]FDG PET-CT imaging. Methods: Nine PSPS-T2 patients (five females, four males; mean age of 53 ± 4.82 years) and nine age- and gender-matched healthy controls (five females, four males; mean age of 53 ± 3.91 years) were included. For each participant, 24 regions of interest (ROIs) were manually drawn, including areas of the vertebral endplates, the intervertebral discs, and the psoas muscles. For each ROI, the mean standardized uptake values (SUVs) were assessed. Group differences were evaluated using repeated measures ANOVA with Bonferroni-adjusted post-hoc pairwise comparisons. Additionally, Pearson correlation analyses examined associations between SUV_mean values and the Numerical Rating Scale (NRS) pain scores. Results: Results demonstrated significantly higher SUV_mean values in healthy controls compared to PSPS-T2 patients, particularly at the superior endplates of L4 and S1, the intervertebral discs at L4-L5 and L5-S1, and the posterior endplates of L4 and L5. Although PSPS-T2 patients exhibited higher SUV_mean values than controls in the psoas muscle, these differences were not statistically significant. Additionally, no significant correlations were found between SUV_mean values and NRS pain scores, suggesting that metabolic activity alone does not directly reflect pain severity. Conclusions: Despite the limited sample size of this pilot study, the metabolic fingerprint of the axial musculoskeletal system was shown to be distinctly different in PSPS-T2 patients compared to healthy controls. This could lead to an improved understanding of PSPS-T2 pathophysiology and might open new doors for better diagnosis and treatment strategies. Full article

Background: Coronary artery disease (CAD) is a leading global cause of mortality. The role of calcium (Ca), a key metabolic and structural element, in atherosclerosis and inflammation remains unclear. Ca influences immune cell function and is a component of atherosclerotic plaques. Hair analysis reflects long-term mineral exposure and may serve as a non-invasive biomarker. Objectives: This pilot study aimed to investigate the association between hair Ca levels and acute coronary syndrome (ACS), and to evaluate correlations with the Systemic Inflammatory Index (SII), Systemic Inflammatory Response Index (SIRI), and selected CAD risk factors. Methods: Ca levels were measured in hair samples from patients undergoing coronary angiography for suspected myocardial infarction. Associations with ACS diagnosis, Syntax score, SII, SIRI, and CVD risk factors were analyzed. Results: Serum calcium levels were not significantly associated with the presence of acute coronary syndrome (ACS) (p = 0.392) or with its clinical subtypes, including ST-elevation myocardial infarction (STEMI), non-ST-elevation myocardial infarction (NSTEMI), and unstable angina (UA) (p = 0.225). Diagnosis of ACS was linked to higher SII (p = 0.028) but not SIRI (p = 0.779). Ca levels correlated negatively with Syntax score (R = −0.19, p = 0.035) and SII (R = −0.22, p = 0.021) and positively with HDL-C (R = 0.18, p = 0.046). Conclusions: Hair calcium content may reflect subclinical inflammation and CAD severity. Although no direct link to ACS was observed, the associations with SII, HDL-C, and Syntax score suggest a potential diagnostic role which should be further explored in larger, well-controlled studies.

Background: Metabolic dysfunction-associated steatotic liver disease (MASLD) is linked to metabolic syndrome, type 2 diabetes, and obesity. This study investigates the relationship between physical capacity, assessed by the Global Physical Capacity Score (GPCS), and MASLD-related parameters, including hepatic steatosis (CAP score), insulin resistance (HOMA-IR), and body mass index (BMI). Methods: A cross-sectional analysis was performed on 204 individuals with MASLD (mean age: 50 years; 57.6% males). Participants underwent physical tests to determine their GPCS. Hepatic steatosis was assessed using FibroScan® (Echosens, Paris, France), and metabolic markers were collected from fasting blood samples. Statistical analyses included linear and logistic regression models adjusted for potential confounders. Results: A higher GPCS was inversely associated with CAP (β = −5.30; p < 0.05), HOMA-IR (β = −0.28; p < 0.001), and BMI (β = −0.96; p < 0.001). Logistic regression analysis confirmed a lower risk of severe hepatic steatosis (OR = 0.44; p < 0.05), obesity (OR = 0.39; p < 0.05), and insulin resistance (OR = 0.32; p < 0.001) in individuals with higher GPCS values. Conclusions: The GPCS may indicate MASLD severity and reflect metabolic and hepatic health. Our findings support the promotion of physical activity and suggest a potential role for GPCS in risk stratification and personalized interventions for patients with MASLD. Full article

Supplementation with probiotics seems to confer protective effects in individuals with schizophrenia (SZ), although available results are inconclusive. The aim of this study was to systematically review existing randomized clinical trials (RCTs) to critically assess the effect of probiotics on psychiatric symptoms, anthropometric indicators, lipid profiles, glycemic indices, inflammation, and oxidative stress in adults with SZ. A systematic search was conducted in four databases from inception until January 2025. Six RCTs were included in the quantitative analysis that demonstrated beneficial effects of probiotics on SZ severity determined via the Positive and Negative Syndrome Scale (PANSS), with significant reductions in PANSS (MD = −0.50, p = 0.001), PANSS Negative (MD = −0.31, p = 0.050), and PANSS General scores (MD = −0.33, p = 0.036), alongside reductions in body weight (MD = −0.92, p = 0.000), body mass index (MD = −0.53, p = 0.016), and total cholesterol (SMD = −0.34, p = 0.005). Furthermore, probiotic interventions reduced baseline glucose (SMD = −0.59, p = 0.000), insulin (MD = −0.68, p = 0.000), and measures of insulin sensitivity/resistance and significantly improved biomarkers of inflammation and oxidative stress. To summarize, this meta-analysis suggests that probiotics may confer beneficial effects in patients with SZ through improving psychiatric symptoms as well as markers of body weight, lipid and glucose metabolism, inflammation, and oxidative stress.

Background/Objectives: Metabolic dysfunction-associated steatotic liver disease (MASLD) is a major cause of chronic liver disease and is closely linked to obesity and metabolic syndrome, necessitating efficient, non-invasive diagnostic tools. Methods: This monocentric cross-sectional study included 178 patients (69.1% with MASLD, 30.9% normal subjects; 55% males; mean age 52.79 ± 12.56 years) who underwent anthropometric and biochemical assessments to determine the visceral adiposity index (VAI), triglyceride–glucose index (TyG), and lipid accumulation product (LAP), along with abdominal ultrasound and vibration-controlled transient elastography (VCTE) with controlled attenuation parameter (CAP). Results: Patients were categorized based on steatosis severity: S0–S1 (n = 64) and S2–S3 (n = 114). The TyG, VAI, and LAP values were significantly higher in S2–S3 cases (p < 0.0001) and showed moderate-to-strong correlations with both steatosis and fibrosis. Predictive models yielded AUROCs of 0.80 (TyG), 0.83 (VAI), and 0.79 (LAP) for diagnosing S2–S3 steatosis. The NAFLD fibrosis score (NFS) and FIB-4 classified fibrosis severity, but 36.8% of cases remained unclassified. Applying the TyG and VAI thresholds reduced this rate to 26.3%. Conclusions: These findings support the TyG, VAI, and LAP as valuable non-invasive biomarkers for MASLD assessment, enhancing the classification accuracy when conventional fibrosis scores are inconclusive.

Background: Post-COVID-19 syndrome (PCS) is defined as the persistence of symptoms 3 months after acute SARS-CoV-2 infection. The long-term prevalence and clinical progression of PCS has not been established. Our aim was to investigate the symptoms in PCS patients, explore the degree of physical activity, according to the fatigue severity score, and analyze its association with basic cardio-pulmonary exercise testing (CPET) parameters. Methods: A total of 192 subjects with history of SARSCoV-2 infection were included. They filled in the Chronic Fatigue Syndrome Questionnaire (CFSQ) and were divided into symptomatic and asymptomatic groups. Forty-seven had persistent post-COVID complaints—reduced physical capacity, fatigue, dyspnea, sleep disturbances, muscle pain. CPET was performed and the pathophysiological parameters in the different fatigue severity groups were compared. Results: Subjects with persistent long-term PCS were divided into two groups—mild (20) and moderate–severe (27), depending on the CFSQ score; forty-eight PCS subjects without complaints served as a control group. The average period between the acute illness and the study was 1028 ± 214 days. Subjects with moderate–severe PCS had more symptoms during CPET (73.6% vs. 24.8% vs. 17.4%), as compared to mild/asymptomatic. The rate of perceived effort was subjective and did not correspond to the workload, heart, or breathing rate in the symptomatic group. These subjects were unable to reach the anaerobic threshold, compared to mild/asymptomatic subjects (51.8% vs. 25%, vs. 12.5%). Patients with moderate–severe PCS showed lower peak VO₂ (24.13 ± 6.1 mL/min/kg vs. 26.73 ± 5.9 mL/min/kg, vs. 27.01 ± 6.3 mL/min/kg), as compared to mild/asymptomatic subjects. Conclusions: Long-term PCS is still present in up to 24% of the general population, more than thirty months after the acute episode. It is characterized by increased perception of symptom burden and diminished aerobic metabolism. A third of the long-term PCS exhibit lower cardio-respiratory fitness, independently from the severity of the symptoms. Full article

Background/Objectives: Hutchinson–Gilford progeria syndrome (HGPS) is a rare genetic disorder that cause premature aging due to LMNA mutations and progerin accumulation. Although lonafarnib, an FDA-approved farnesyltransferase inhibitor, offers modest extension of life, the disease remains progressive. As progeria is associated with stem cell depletion and mesenchymal stem cell (MSC) therapy has shown efficacy in treating atherosclerosis, we aimed to evaluate its efficacy and safety in HGPS. Methods: A 7-year-old male with classic HGPS and preexisting severe cerebrovascular disease received four intravenous infusion of bone marrow-derived MSCs (2.5 × 10⁵ cells/kg) over 8 months. Growth, metabolic, cardiovascular, musculoskeletal, auditory, and inflammatory cytokines were monitored throughout the study. Prophylactic enoxaparin was administered to prevent vascular complications. Results: MSC therapy was associated with improved lean body mass (11.5%), bone mineral density (L-spine z-score: 0.55 → 2.03), reduced arterial stiffness (9.98% reductionin pulse wave velocity), joint range of motion, dentition, and decreased sICAM-1 levels. However, Cardiovascular deterioration continued, and the patient passed away 10 months after the fourth dose, likely due to progression of the underlying vascular disease. No severe adverse effects were attributed to MSC therapy. Conclusions: MSC therapy may offer short-term benefits in arterial stiffness, bone health and inflammation in HGPS without notable safety concerns. Further studies are warranted to validate these findings, explore earlier intervention, and determine long-term efficacy and optimal dosing strategies. Full article

Background: Patients with irritable bowel syndrome (IBS) often experience comorbid psychological conditions, notably depression and anxiety. Evidence suggests that these conditions are linked to gut barrier dysfunction, dysbiosis, and chronic inflammation. All these factors are central to IBS pathophysiology and mood disturbances. Polyunsaturated fatty acids (PUFAs) play crucial roles in modulating inflammation and depression. This study examined the associations among intestinal permeability, PUFA profiles, low-grade inflammation, and depression severity in IBS patients with diarrhea (IBS-D). Methods: Forty-three IBS-D patients (7 men, 36 women; 44.56 ± 1.52 years) were categorized into depressed (IBS-D(d+)) and non-depressed (IBS-D(d−)) groups according to scores on the depression subscale of the Symptom Checklist-90-Revised (SCL-90-R). Biomarkers of small intestinal permeability (s-IP) were assessed in urine and blood, alongside erythrocyte membrane PUFA composition, dysbiosis, and inflammation indices. Results: IBS-D (d+) patients exhibited elevated s-IP and altered PUFA metabolism compared to their IBS-D (d−) counterparts. Additionally, in the first group, omega-3 PUFA concentrations inversely correlated with s-IP biomarkers, while the omega-6/omega-3 ratio showed a positive correlation. Moreover, depression severity is significantly associated with s-IP markers and omega-3 PUFA levels. Lastly, IBS-D (d+) patients exhibited higher levels of dysbiosis and pro-inflammatory cytokines than IBS-D (d−) patients. Conclusions: These findings highlight the interplay between intestinal barrier integrity and PUFA metabolism in IBS-D patients with depression, suggesting that s-IP markers and erythrocyte PUFA profiles could represent novel therapeutic targets for managing depression in this population. This study was registered on ClinicalTrials.gov (NCT03423069), with a date of registration of 30 January 2018. Full article

Background/Objectives: Severe mental illnesses such as schizophrenia, major depressive disorder, and bipolar disorder are often accompanied by metabolic comorbidities. While the role of vitamins in physical health is well-established, their involvement in psychiatric disorders has garnered increasing attention in recent years. Methods: We conducted a cross-sectional analysis of 1003 patients diagnosed with severe mental illnesses. Vitamin D, B9, and B12 serum levels were measured, and deficiencies were defined using established clinical cutoffs. Multivariate regression analyses were performed to identify associations between vitamin deficiencies and clinical outcomes. Results: Our findings revealed that vitamin deficiencies were prevalent across all diagnostic groups, with particularly high rates in patients with schizophrenia and major depressive disorder. Vitamin D deficiency was significantly associated with worse psychiatric outcomes, including increased depressive symptoms (adjusted OR = 1.89, p = 0.018), lower Global Assessment of Functioning scores (adjusted OR = −0.18, p < 0.001), and higher rates of metabolic syndrome (adjusted OR = 1.97, p = 0.007). Folate and B12 deficiencies were also linked to greater psychiatric symptom severity and metabolic disturbances, including increased risks of obesity and dyslipidemia. Conclusions: Our study highlights the critical role of vitamins deficiencies in both psychiatric and metabolic health of patients with severe mental illnesses. These findings underscore the importance of routine screening and correction of these deficiencies as part of comprehensive care in psychiatric populations. The integration of nutritional interventions may offer a novel and holistic approach to improving both mental and physical health outcomes. Full article

Coronary artery atherosclerosis is a common condition characterized by different symptomatology and incidences of risk factors. The disease manifestation may differ; therefore, proper diagnosis is essential. The preventive, diagnostic, and therapeutic arms are still developing to improve patient outcomes. Among diagnostic steps, the non-invasive tools for evaluating non-classical factors related to metabolomic profiles are gaining attention. The aim of this study was to investigate possible metabolic profiling differences between patients with chronic coronary artery disease (CAD) and a control group based on plasma sphingomyelin levels. The study group consisted of 23 patients (72% male, median age of 69 (63–72) years) presenting with chronic coronary syndrome and confirmed epicardial disease in coronary angiography and 15 patients (33% male, median age of 70 (64–72) years) with normal angiographic results. Clinical data were recorded, and blood samples were collected for standard biochemical laboratory assessment and metabolomic profiling. The plasma sphingomyelin levels were evaluated in patients with different degrees of coronary artery atherosclerosis involvement. In addition, the severity of the epicardial disease was estimated by the Gensini Score. The study subgroups did not differ in terms of age (p = 0.765) and co-morbidities, though the male sex was more common in the CAD group (p = 0.007). The analysis revealed significant differences regarding neutrophil count (p = 0.014), neutrophil-to-lymphocyte ratio (NLR) (p = 0.016), and high-density lipoprotein (HDL) (p = 0.003). Among different plasma sphingomyelin species, there was a significant difference in plasma SM42:1 level (16.2 (14.2–19.1) vs. 20.8 (18.9–21.7) (p = 0.044) between the CAD and control groups, respectively. The SM 42:1 plasma level was independent of the number of involved epicardial arteries (p = 0.109). However, Spearman correlations tests were performed between the SM 42:1 plasma level and the number of coronary arteries diagnosed with atherosclerosis disease (rho = −0.356, p = 0.014) and the severity of the disease measured by the Gensini Score (rho = −0.403, p = 0.006). There was no correlation between plasma sphingomyelin levels and NLR (Spearman’s rho = −0.135, p = 0.420), suggesting a lack of inflammatory associations. Further, sphingomyelins showed no relationship with coronary artery disease risk factors such as dyslipidemia and diabetes. Lower plasma SM 42:1 levels were revealed in the CAD group compared with the control group, indicating a possible significance of sphingomyelin 42:1 in coronary artery disease progression.

Background and Objectives: Growing evidence suggested that abnormal lipid metabolism (ALM) was associated with an increased severity of depressive symptoms, but no previous studies have examined the differences in comorbid ALM in major depressive disorder (MDD) patients of different ages of onset. We aim to compare the differences in the prevalence and clinical correlates of ALM between early-onset and late-onset patients with first-episode and drug-naive (FEDN) MDD patients. Methods: Using a cross-sectional design, we recruited a total of 1718 FEDN MDD outpatients in this study. We used the 17-item Hamilton Rating Scale for Depression (HAMD-17), The Hamilton Anxiety Rating Scale (HAMA), the Positive and Negative Syndrome Scale (PANSS) positive subscale, and Clinical Global Impression-Severity Scale (CGI-S) to assess their depression, anxiety, and psychotic symptoms and clinical severity, respectively. Results: There were 349 patients (20.3%) in the early-onset subgroup and 1369 (79.7%) in the late-onset subgroup. In this study, 65.1% (1188/1718) of patients were diagnosed with ALM. The prevalence of ALM in the late-onset group (81.5%, 1116/1369) was significantly higher than that in the early-onset group (20.6%, 72/349) (p = 0.36, OR = 1.147, 95%CI = 0.855–1.537). The HAMD total score (OR = 1.34, 95% CI = 1.18–1.53, p < 0.001) was the only risk factor for ALM in early-onset MDD patients. In late-onset MDD patients, the HAMD total score (OR = 1.19, 95% CI = 1.11–1.28, p < 0.001), TSH (OR = 1.25, 95% CI = 1.16–1.36, p < 0.001), CGI (OR = 1.7, 95% CI = 1.31–2.19, p < 0.001), and anxiety (OR = 2.22, 95% CI = 1.23–4.02, p = 0.008) were risk factors for ALM. Conclusion and Scientific Significance: Our results suggest that there are significant differences in the prevalence and clinical factors of comorbid ALM between early-onset and late-onset FEND MDD patients.

Background/Objectives: This study assessed the association among perceived stress, anxiety, and depression with both the metabolic syndrome (MetS) risk and diagnostic status among young adults in the Deep South. Methods: Participants included 132 young adults aged 18–39 (M_age = 27.73, SD = 11.11; M_BMI = 27.6, SD = 6.8; 56.5% female; 55.7% White) living in Mississippi. In addition to completing self-report measures of perceived stress, anxiety, and depression, all of the participants underwent anthropometric, blood pressure, and fasting blood glucose and lipid assessments to ascertain the MetS status. The participants were provided with both a MetS diagnosis (defined as a dichotomous yes/no variable) as well as a continuous MetS risk severity score determined using existing equations. The risk scores ranged from −1 to +1, with positive scores indicating an increased risk for MetS. Results: After controlling for age, biological sex, race, medication use, and education level, multiple regression models revealed significant positive relationships between perceived stress (b = 0.03; p = 0.017) and anxiety symptoms (b = 0.01; p = 0.039) with the MetS severity. Perceived stress (p = 0.017) and anxiety symptoms (p = 0.043) were also significantly higher among participants with MetS compared to those without. There were no significant associations between the MetS severity and depressive symptoms, and no differences in depressive symptoms in participants with versus without MetS. Conclusions: The results highlight the role of stress and anxiety not only in MetS but in the overall metabolic risk among young adults living in the Deep South. The results highlight the importance of intervening on stress and anxiety early in adulthood to help mitigate cardiometabolic health risk. Full article

Background/Objectives: Evidence supports the benefits of concurrent training (CT), which combines endurance and resistance exercises, for enhancing health and physical fitness. Recently, low-volume, time-efficient exercise approaches such as low-volume high-intensity interval training (LOW-HIIT), whole-body electromyostimulation (WB-EMS), and single-set resistance training (1-RT) have gained popularity for their feasibility and efficacy in improving various health outcomes. This study investigated the effects of low-volume CT, focusing on (1) whether exercise order affects cardiometabolic health, inflammation, and fitness adaptations and (2) which combination, LOW-HIIT plus WB-EMS or LOW-HIIT plus 1-RT, yields better results. Methods: Ninety-three obese metabolic syndrome (MetS) patients undergoing caloric restriction were randomly assigned to four groups performing the different low-volume CT protocols over 12 weeks. Outcomes included cardiometabolic, inflammatory, and fitness parameters. Results: In both combinations, no significant differences were found regarding exercise order. However, the pooled LOW-HIIT and 1-RT group achieved superior improvements in blood pressure, blood lipids, inflammation markers (CRP, hsCRP), the MetS severity score, and overall fitness compared to the LOW-HIIT and WB-EMS combination. Compared to previous studies using these modalities individually, LOW-HIIT plus 1-RT appeared to further reduce inflammation, whereas LOW-HIIT combined with WB-EMS was less effective for cardiometabolic health, potentially due to interference effects between modalities. Conclusions: While LOW-HIIT plus WB-EMS appears to be a viable option for individuals unable to perform traditional resistance training, the findings suggest prioritizing LOW-HIIT plus 1-RT to maximize health outcomes. These findings highlight the importance of tailored exercise prescriptions and the need for further research into optimizing CT protocols for diverse populations. Full article

Background/objectives: Psoriasis is a chronic inflammatory autoimmune disease with important systemic and psychosocial impacts. The association with metabolic syndrome (MS) impairs disease severity and negatively influences patient-reported outcomes, particularly their quality of life as measured by the Dermatology Life Quality Index (DLQI). This study aims to investigate the relationship between systemic inflammation, DLQI scores and disease severity, focusing on the persistent impact of MS on patient outcomes after one year of treatment. Methods: This retrospective cross-sectional study included 150 psoriasis patients, with 74 also meeting the diagnostic criteria for MS. Clinical and inflammatory markers such as systemic immune–inflammatory index (SII), cytokines (IL-17A, IL-23), leptin, BMI and triglycerides were analyzed alongside PASI and DLQI scores. Results: Patients with MS had significantly higher PASI and DLQI scores compared to those without MS, reflecting worse disease severity and quality of life (p < 0.01). Elevated SII levels were strongly associated with higher DLQI scores (p < 0.01). Despite considerable reductions in PASI scores over one year of treatment, DLQI scores indicated a persistent negative impact of MS on quality of life. Notably, markers of systemic inflammation, such as SII, leptin and cytokines, correlated positively with both PASI and DLQI scores, highlighting the role of systemic inflammation in disease burden. Conclusions: This study underlines the significant role of systemic inflammation and metabolic comorbidities in amplifying the burden of psoriasis. The persistent impact of MS on quality of life despite clinical improvement underscores the need for comprehensive treatment approaches targeting systemic inflammation, metabolic health and psychosocial factors to improve long-term outcomes.
