RÉSUMÉ
This study aimed to investigate the association between high-sensitivity C-reactive protein (hs-CRP) levels, as a surrogate marker of systemic inflammation, and renal function among Korean adults grouped by age, sex, and body mass index. This study analyzed data obtained from the Korea National Health and Nutrition Examination Survey 2015 to 2018, a cross-sectional and nationally representative survey conducted by the Korean Centers for Disease Control and Prevention. Of the 22,451 subjects included in this study, 19,607 (87.3%) and 2844 (12.7%) had normal kidney function and incident chronic kidney disease, respectively. Reduced renal function was more frequently observed in subjects with high hs-CRP levels than in those with low hs-CRP levels (odds ratio [OR], 1.438; 95% confidence interval [CI], 1.234-1.674). In the group agedâ ≥â 65 years, the odds of reduced renal function were higher among subjects with a high hs-CRP level compared to those with a low hs-CRP level (OR, 1.528; 95% CI, 1.191-1.960). The association between hs-CRP level and renal function was observed only in women (OR, 2.485; 95% CI, 1.779-3.470) and further stratified by age and sex, the odds of reduced renal function were likely higher in women agedâ ≥â 65 years with a high hs-CRP level (OR, 2.338; 95% CI, 1.622-3.369). Moreover, reduced renal function was more observed in subjects agedâ ≥â 65 years and those with a body mass indexâ <â 25 kg/m2 (OR, 1.502; 95% CI, 1.087-2.075). This study showed that a high hs-CRP level likely contributes to the increased prevalence of reduced renal function. This association may aid the identification of individuals at high risk for reduced renal function, especially elderly women, in clinical or public health practice.

BACKGROUND: Current evidence linking sedentary behavior (SB), physical activity (PA), and inflammation raises questions about their causal relationships, prompting concerns about potential residual confounding or reverse causation. METHODS: A bidirectional Mendelian randomization (MR) analysis was conducted. SB data (n = 408,815) from "computer use," "television watching," and "driving" were included. The PA data encompassed nine types of PA (n = 460,376) over the last four weeks and included data on the frequency of vigorous PA (n = 440,512) and moderate PA (n = 440,266) for over 10 min. Additionally, three genome-wide association study datasets (n = 64,949) on light, moderate, and vigorous exercise were included to minimize potential bias from changes in exercise intensity. Inflammation data included levels of C-reactive protein (CRP) (n = 575,531), glycoprotein acetyl (GlycA) (n = 115,082), interleukin (IL)-8, IL-6, IL-6 receptor (IL-6R), and soluble IL-6R (sIL-6R) (n = 35,278). All datasets represented participants of European ancestry. RESULTS: Television watching as an SB showed significant positive causal effects on GlycA and CRP (inverse variance weighted (IVW), odds ratios (OR): 1.34, 95% confidence intervals (CI): 1.25-1.44, p = 3.570 × 10-17; IVW, OR: 1.21, 95% CI: 1.16-1.26, p = 1.500 × 10-19, respectively), with more robust evidence for GlycA. In the direction from inflammation to PA, a negative causal relationship between CRP and"number of days/week of moderate PA 10+ minutes"was observed (IVW, OR: 0.92, 95% CI: 0.89-0.96, p = 3.260 × 10-5). Sensitivity analyses were used to verify the robustness and reliability of the results. However, other initially observed associations ceased to be significant after controlling for obesity-related confounders. CONCLUSION: Our MR analysis suggested a potential causal relationship between television watching and chronic low-grade inflammation, with more substantial evidence for GlycA. Additionally, different types of SB may have varying effects on inflammation. Obesity-related traits could partly or entirely influence the relationship between SB, PA, and inflammatory markers. Furthermore, Our findings indicate that SB is an independent risk factor for inflammation, separate from PA, and highlight the different mechanisms by which SB and PA affect disease.

The main objective of this work was to investigate the mechanism of Astragalus aqueous extract ulcer healing in diabetic foot model rats through the hypoxia-inducible factor 1-alpha (HIF-1É)/vascular endothelial growth factor (VEGF) signalling pathway. Fifty specific-pathogen-free male Sprague Dawley rats were divided into blank (A), model control (B), Astragalus extract (C) and mupirocin (D) treatment groups. Group A received a regular diet, whereas the other groups received a high-fat/high-sugar diet and intraperitoneal streptozotocin injections to induce diabetes. Diabetic foot ulcers were created via skin excision. Subsequently, ulcers were debrided daily. Groups B, C and D received wet saline gauze, wet gauze with Astragalus extract and gauze with mupirocin, respectively, on the affected area. Group A received no treatment. After 14 days, the rats were assessed for ulcer healing and general condition. Immunohistochemistry was used to detect HIF-1É and VEGF levels in the dorsalis pedis artery, and ELISA was used to determine serum IL-6 and CRP levels. The results revealed that Groups C and D had significantly faster ulcer healing compared with Group B (p < 0.01), and ulcer healing was faster in Group C than in Group D (p < 0.01). Group C exhibited notably higher HIF-1É and VEGF protein expression levels compared with Groups B and D (p < 0.01). IL-6 and CRP expression levels in Groups C and D were significantly lower than those in Group B (p < 0.01). In summary, Astragalus aqueous extract effectively treats diabetic foot ulcers by up-regulating HIF-1É and VEGF expression, activating the HIF-1É/VEGF pathway, improving local tissue ischaemia and hypoxia, promoting collateral circulation and enhancing dorsalis pedis artery formation, thereby accelerating ulcer repair in diabetic rats.

AIM: To determine biomarkers of anemia of chronic disease (ACD) in patients with glomerulonephritis (GN) in the early stages of CKD, to assess their role as risk factors for cardiovascular complications (CVС). MATERIALS AND METHODS: Seventy nine patients with GN were studied, among them: 40 with primary Ñhronic GN (CGN), 39 with secondary forms:19 - GN with ANCA-associated systemic vasculitis, 20 - GN with systemic lupus erythematosus (SLE) at early (all I-II) CKD stages. In all patients, the level of serum C-reactive protein (CRP), hepcidin, interferon γ, and the circulating form of protein Klotho (s-Klotho) were determined. When a relative iron deficiency was detected [transferrin iron saturation coefficient (TSAT) <20%], patients were administered parenterally iron [III] sucrose hydroxide complex (Venofer). RESULTS: The frequency of anemia among patients with systemic diseases is 3.2 times higher than among patients with primary CGN. Patients with anemia (group I; n=43) had higher rates of daily proteinuria (p<0.001), systolic blood pressure (p<0.05), serum levels of interferon γ (p<0.001) and hepcidin (p<0.001) and lower values of eGFR (p<0.05) than patients without anemia (group II; n=36). A strong inverse correlation was noted between the level of hepcidin and the content of iron in serum (r=-0.856; p<0.001), between the level of hemoglobin and the level of interferon γ (r=-0.447; p<0.05), hepcidin (r=-0.459; p<0.05) and CRP (r=-0.453; p<0.05). A significant inverse correlation was found between the level of hemoglobin and CVC risk factors - the value of systolic blood pressure (r=-0.512; p<0.05) and the mass index of the left ventricular myocardium (r=-0.619; p<0.01). At the same time, the contribution of 2 from 6 analyzed factors, hepcidin and eGFR, to the development of ACD was 92.5%, of which 86.6% accounted for hepcidin. A strong direct correlation was also found between a decrease in hemoglobin level and a decrease in the level of s-Klotho protein (r=0.645; p<0.001), a decrease in the level of s-Klotho and an increase in the level of serum hepcidin (r=-0.541; p<0.05). The leading value of anemia (beta -0,29; p=0,04) and depression of the s-Klotho level (beta -0,44; p=0,02) as independent cardiovascular risk factors in this group of patients was confirmed by multivariate analysis. In patients with identified deficiency of iron (n=40), after 3-4 weeks of intravenous administration of venofer, the target level of hemoglobin (Ðb>120 g/l) and transferrin saturation with iron (TSAT>20%) were achieved. CONCLUSION: Among the biomarkers of ACD in patients with immunoinflammatory diseases of the kidneys (primary and secondary СGN), the increase in the serum level of hepcidin is greatest importance. The concomitant to anemia decrease in s-Klotho is a leading risk factor for CVС in CKD. Early correction of ACD with iron supplements makes it possible to achieve target levels of Hb and TSAT and have subsequently a positive effect on the production of s-Klotho and the severity of left ventricular hypertrophia.

PURPOSE OF REVIEW: The following article examines the rationale for an inflammation-first approach for diagnosing cachexia and how the current Global Leadership Initiative on Malnutrition (GLIM) framework may be adapted to facilitate this. RECENT FINDINGS: Recently, the GLIM have published guidance on the measurement of inflammation in the context of cachexia, advocating that C-reactive protein (CRP) should be utilized for quantification. The inclusion of a systemic inflammatory biomarker for the diagnosis of cachexia questions whether it may be more aptly considered a systemic inflammatory syndrome. SUMMARY: The current consensus of the GLIM is that cachexia is 'disease-related malnutrition with inflammation'. In line with this definition, the GLIM proposed a two-step diagnostic framework: screening for malnutrition using validated screening tools and then confirming the presence of disease-related malnutrition with phenotypic (nonvolitional weight loss, low BMI, and reduced muscle mass) and aetiologic criterion reduced food intake/assimilation, and inflammation or disease burden). The GLIM are to be commended for guidance on the measurement of systemic inflammation in their current proposal, given the relative importance to clinical outcomes in patients with cancer. However, the use of CRP is somewhat rudimentary and contrasts other cancer cachexia guidelines and contemporary clinical cancer research.

The effect of systemic inflammation, represented by high-sensitivity C-reactive protein (hsCRP), on triglyceride glucose (TyG) index-associated cardiovascular risk in patients with acute coronary syndrome (ACS) undergoing percutaneous coronary intervention (PCI) has not yet been determined. This study was a retrospective analysis of a single-center prospective registry and finally included 1701 patients (age, 60 ± 10 years; male, 76.7%). The primary endpoint was defined as major adverse cardiovascular events (MACE), including cardiovascular mortality, non-fatal stroke, and non-fatal myocardial infarction. In the multivariate COX regression model that included the GRACE risk score, higher TyG index was significantly associated with a greater incidence of MACE in patients with hsCRP levels less than 2 mg/L but not 2 mg/L or more (P for interaction = 0.039). Each unit increase in the TyG index was independently associated with a 52% increased risk of MACE only in patients with hsCRP levels less than 2 mg/L (P = 0.021). After adjustment for other confounding factors, including the GRACE risk score, compared with those in the group of TyG index < 8.62 and hsCRP < 2 mg/L, patients in the group of TyG index ≥ 8.62 and hsCRP ≥ 2 mg/L had a 3.9 times higher hazard ratio for developing MACE. The addition of both TyG index and hsCRP had an incremental effect on the predictive ability of the GRACE risk score-based prognostic model for MACE (C-statistic: increased from 0.631 to 0.661; cNRI: 0.146, P = 0.012; IDI: 0.009, P < 0.001). In conclusion, there was a significant interaction between the TyG index and hsCRP for the risk of MACE, and the TyG index was reliably and independently associated with MACE only when hsCRP levels were less than 2 mg/L. Furthermore, high TyG index and high hsCRP levels synergistically increased the risk of MACE, suggesting that the prognostic value of TyG index combined with hsCRP might be promising in patients with ACS undergoing PCI.

This study compared the capacity of two different models of HIIT [high-(HC) and low-(LC) compression], with or without the use of berberine (BBR), on NOD-like receptor pyrin domain-containing protein-3 (NLRP3), H19, interleukin (IL)-1ß, high-sensitivity C-reactive protein (hs-CRP), and insulin resistance markers. Fifty-four middle-aged men with overweight or obesity and prediabetes [fasting blood glucose (FBG) 110-180 mg/dL] were randomly and equally assigned to the HC, LC, HC + BBR, LC + BBR, BBR, and non-exercising control (CON) groups. The HC (2:1 work-to-rest) and LC (1:1 work-to-rest) home-based training programs included 2-4 sets of 8 exercises at 80%-95% HRmax, twice a week for 8 weeks. Participants in the berberine groups received approximately 1000 mg daily. All exercise interventions led to a significant reduction in hs-CRP, IL-1ß, insulin, FBG, and insulin resistance index (HOMA-IR) versus CON. Notably, there was a significant reduction in FBG and HOMA-IR with the BBR group compared to the baseline. Both NLRP3 and H19 experienced a significant drop only with LC in comparison to the baseline. While both exercise protocols were beneficial overall, LC uniquely exhibited more anti-inflammatory effects, as indicated by reductions in H19 and NLRP3. However, the addition of berberine to the exercise programs did not demonstrate additional benefits.

Background: Carotid endarterectomy (CEA) for the prevention of upcoming vascular and cerebral events is necessary in patients with high-grade stenosis (≥70%). In the framework of the Italian National project Age.It, a pilot study was proposed aiming at the discovery of a molecular signature with predictive potential of carotid stenosis comparing 65+ asymptomatic and symptomatic inpatients. Methods: A total of 42 inpatients have been enrolled, including 26 men and 16 women, with a mean age of 74 ± 6 years. Sixteen symptomatic and 26 asymptomatic inpatients with ≥70% carotid stenosis underwent CEA, according to the recommendations of the European Society for Vascular Surgery and the Society for Vascular Surgeons. Plaque biopsies and peripheral blood samples from the same individuals were obtained. Hematobiochemical analyses were conducted on all inpatients, and plasma cytokines/molecules, such as microRNAs (miRs), IL-6, sIL-6Ralpha, sgp130, myostatin (GDF8), follistatin, activin A, CXCL9, FGF21, and fibronectin, were measured using the ELISA standard technique. MiR profiles were obtained in the discovery phase including four symptomatic and four asymptomatic inpatients (both plasma and plaque samples), testing 734 miRs. MiRs emerging from the profiling comparison were validated through RT-qPCR analysis in the total cohort. Results and conclusion: The two groups of inpatients differ in the expression levels of blood c-miRs-126-5p and -1271-5p (but not in their plaques), which are more expressed in symptomatic subjects. Three cytokines were significant between the two groups: IL-6, GDF8, and CXCL9. Using receiver operating characteristic (ROC) analysis with a machine learning-based approach, the most significant blood molecular signature encompasses albumin, C-reactive protein (CRP), the percentage of monocytes, and CXCL9, allowing for the distinction of the two groups (AUC = 0.83, 95% c.i. [0.85, 0.81], p = 0.0028). The potential of the molecular signature will be tested in a second cohort of monitored patients, allowing the application of a predictive model and the final evaluation of cost/benefit for an assessable screening test.

Aim: The index study aimed to investigate the clinical impact of initial high-sensitivity C-reactive protein (hs-CRP) on outcomes in nonvalvular atrial fibrillation (AF). Methods: Single-center, prospective, observational study recruiting all recently diagnosed treatment-naive AF patients. Hs-CRP was measured at baseline and patients were followed for 24 months. Results: A total of 126 patients with a mean age of 66.2 (±12.0) years were enrolled. The composite outcome of major adverse cardiac or cerebrovascular events (MACCE) occurred in 19 (17.7%) at 24 months. Raised initial hs-CRP emerged as an independent predictor of MACCE on regression analysis (OR: 1.569, 95% CI: 1.289-1.912; p < 0.001). Conclusion: Raised hs-CRP was an independent predictor of MACCE at 24 months. It allows for early identification of high-risk patients.
Atrial fibrillation (AF) is the most common cause of irregular heartbeat in adults. It has a significant association with clot formation in the heart and acute vessel closure throughout the vascular system particularly of the brain causing stroke. Stroke has a significant impact on quality of life and also is associated with an increased likelihood of death. Inflammation has been linked to the development and progression of AF. In this study, we evaluated the role of a simple inflammatory blood parameter high sensitivity C-reactive protein (hs-CRP) with adverse outcomes in 126 AF patients at our center over a period of 2 years. We concluded that hs-CRP was an independent predictor of worse cardiovascular outcomes in AF patients and can help in the earlier identification of high-risk patients, for whom appropriate measures can be taken to prevent adverse events.

BACKGROUND: Inguinal hernia repair is a frequently performed surgical procedure, with laparoscopic repair emerging as the preferred approach due to its lower complication rate and faster recovery compared to open repair. Mesh-based tension-free repair is the gold standard for both methods. In recent years, robotic hernia repair has been introduced as an alternative to laparoscopic repair, offering advantages such as decreased postoperative pain and improved ergonomics. This study aims to compare the short- and long-term outcomes, including the surgical stress response, postoperative complications, quality of life, and sexual function, between robotic-assisted transabdominal preperitoneal (rTAPP) and laparoscopic TAPP inguinal hernia repairs. METHODS: This randomized controlled trial will involve 150 patients from the Surgical Department of the University Hospital of Southern Denmark, randomized to undergo either rTAPP or laparoscopic TAPP. Surgical stress will be quantified by measuring C-reactive protein (CRP) and cytokine levels. Secondary outcomes include complication rates, quality of life, sexual function, and operative times. Data analysis will adhere to the intention-to-treat principle and will be conducted once all patient data are collected, with outcomes assessed at various postoperative intervals. DISCUSSION: This study holds significance in evaluating the potential advantages of robotic-assisted surgery in the context of inguinal hernia repairs. It is hypothesized that rTAPP will result in a lower surgical stress response and potentially lower the risk of postoperative complications compared to conventional laparoscopic TAPP. The implications of this research could influence future surgical practices and guidelines, with a focus on patient recovery and healthcare costs. The findings of this study will contribute to the ongoing discourse surrounding the utilization of robotic systems in surgery, potentially advocating for their broader implementation if the benefits are substantiated.

Well-controlled type 1 diabetes (T1DM) is characterized by inflammation and endothelial dysfunction, thus constituting a suitable model of subclinical cardiovascular disease (CVD). miR-199b-5p overexpression in murine CVD has shown proatherosclerotic effects. We hypothesized that miR-199b-5p would be overexpressed in subclinical CVD yet downregulated following metformin therapy. Inflammatory and vascular markers were measured in 29 individuals with T1DM and 20 matched healthy controls (HCs). miR-199b-5p expression in CFU-Hill's colonies was analyzed from each study group, and correlations with inflammatory/vascular health indices were evaluated. Significant upregulation of miR-199b-5p was observed in T1DM, which was significantly downregulated by metformin. miR-199b-5p correlated positively with vascular endothelial growth factor-D and c-reactive protein (CRP: nonsignificant). ROC analysis determined miR-199b-5p to define subclinical CVD by discriminating between HCs and T1DM individuals. ROC analyses of HbA1c and CRP showed that the upregulation of miR-199b-5p in T1DM individuals defined subclinical CVD at HbA1c > 44.25 mmol and CRP > 4.35 × 106 pg/mL. Ingenuity pathway analysis predicted miR-199b-5p to inhibit the target genes SIRT1, ETS1, and JAG1. Metformin was predicted to downregulate miR-199b-5p via NFATC2 and STAT3 and reverse its downstream effects. This study validated the antiangiogenic properties of miR-199b-5p and substantiated miR-199b-5p overexpression as a biomarker of subclinical CVD. The downregulation of miR-199b-5p by metformin confirmed its cardio-protective effect.

BACKGROUND: Obesity is characterized by a chronic low-grade inflammatory condition. Two emerging inflammatory biomarkers, the systemic immune-inflammation index (SII) and the systemic inflammation response index (SIRI), have gained attention. However, the relationships between obesity and SII/SRI remain unclear. METHODS: In this study, we analyzed data from the National Health and Nutrition Examination Survey (NHANES) from 2011 to 2018 among adults. SII-SIRI/SII/SIRI were categorized into three groups based on tertiles. The association between obesity and SII-SIRI/SII/SIRI was assessed by multivariable logistic regression models. Restricted cubic spline (RCS) plots were used to examine the nonlinear association between obesity and SII/SIRI. Finally, potential independent associations between obesity and SII/SIRI were further explored using subgroup analyses. RESULTS: The study included 20,011 adults, of whom 7,890 (39.32%) were obesity. In model 1, participants in the high (Q3) level of SII-SIRI had a significantly association with obesity than those in the low (Q1) level group. The high level of SII and SIRI were positively associated with obesity as compared to low levels. Model 2 revealed a positive association between obesity and high levels of SII-SIRI/SII/SIRI. Model 3 demonstrated a similar trend. RCS curves revealed a nonlinear association linking obesity to SII/SIRI. Subgroup analysis showed an interaction between SII/SIRI and age. CONCLUSIONS: Our research suggested that obesity was positively associated with SII-SIRI/SII/SIRI in U.S. adults. SII/SIRI may represent a cost-effective and direct approach to assessing obesity.

AIMS: To assess the correlation between high-sensitivity C-reactive protein (Hs-CRP) and the prevalence of cardiovascular disease (CVD) among individuals with diabetes. METHODS: A total of 1,555 participants from the National Health and Nutrition Examination Survey were enrolled in this cross-sectional study after excluding individuals without diabetes and those who lacked data on Hs-CRP, diabetes and CVD. All participants were divided into four groups based on quartiles of Hs-CRP: Q1 (≤ 1.20 mg/L), Q2 (1.20-2.86 mg/L), Q3 (2.86-6.40 mg/L), and Q4 (> 6.40 mg/L). Logistic regression analysis, subgroup analysis and restricted cubic spline (RCS) analysis were used to evaluate the correlation between Hs-CRP and the prevalence of CVD in individuals with diabetes. RESULTS: In univariate logistic regression analysis, a higher level of Hs-CRP was associated with a higher prevalence of CVD (P < 0.05). In the multivariate logistic regression analysis adjusting for confounders, the correlation between Hs-CRP and the prevalence of CVD remained significant (Q3 vs. Q1, OR: 1.505, 95% CI: 1.056-2.147, P = 0.024; Q4 vs. Q1, OR: 1.711, 95% CI: 1.171-2.499, P = 0.006; log10(Hs-CRP), OR: 1.504, 95% CI: 1.168-1.935, P = 0.002). Further subgroup analysis showed that a higher Hs-CRP was independently associated with a higher prevalence of CVD in the < 60 years, male, non-hypertension and non-hypercholesterolemia subgroups (P < 0.05). Additionally, RCS analysis revealed a linear positive correlation between Hs-CRP and CVD prevalence (P for nonlinearity = 0.244). CONCLUSION: A higher level of Hs-CRP was closely related to a higher prevalence of CVD in people with diabetes.

OBJECTIVE: To observe the clinical effect of pricking-cupping combined with auricular thumbtack needle for postherpetic neuralgia (PHN) of qi stagnation and blood stasis on chest and waist. METHODS: A total of 98 patients with PHN of qi stagnation and blood stasis on chest and waist were randomized into an observation group (49 cases, 1 case was eliminated, 1 case dropped out) and a control group (49 cases, 1 case dropped out). In the observation group, treatment of pricking-cupping combined with auricular thumbtack needle was delivered, pricking and cupping were applied at Jiaji points (EX-B 2) at the related spinal segments corresponding to the pain sites and regional ashi points, once every other day, auricular thumbtack needle was applied at Xin (CO15), Shenmen (TF4), Neifenmi (CO18), Pizhixia (AT4), etc., once every 3 days. In the control group, pregabalin capsule was taken orally, 75 mg a time, twice a day. The treatment of 4 weeks was required in the two groups. Before and after treatment, the scores of TCM symptom, visual analogue scale (VAS), Pittsburgh sleep quality index (PSQI), self-rating depression scale (SDS) and self-rating anxiety scale (SAS) were observed, the serum levels of immunoglobulin G (IgG), interleukin-6 (IL-6), C-reactive protein (CRP) were detected, and the clinical efficacy and safety were evaluated in the two groups. RESULTS: After treatment, the item scores and total scores of TCM symptom, as well as the scores of VAS, PSQI, SDS and SAS were decreased compared with those before treatment (P<0.05); the item scores of pruritus degree, tactile sensitivity, skin numbness and total score of TCM symptom, as well as the scores of VAS, PSQI, SDS and SAS in the observation group were lower than those in the control group (P<0.05). After treatment, the serum levels of IgG were increased (P<0.05), while the serum levels of IL-6 and CRP were decreased (P<0.05) compared with those before treatment in the two groups; in the observation group, the serum level of IgG was higher (P<0.05), while the serum levels of IL-6 and CRP were lower (P<0.05) than those in the control group. The total effective rate was 95.7% (45/47) in the observation group, which was superior to 77.1% (37/48) in the control group (P<0.05). The incidence rate of adverse reaction was 6.4% (3/47) in the observation group, which was lower than 12.5% (6/48) in the control group (P<0.05). CONCLUSION: Pricking-cupping combined with auricular thumbtack needle can effectively relieve the clinical symptoms in patients with PHN of qi stagnation and blood stasis on chest and waist, reduce the pigmentation of herpes and improve itch or burning, numb sensations in the skin lesions, improve the sleep quality and relieve anxiety and depression.

Pentraxin 3 (PTX3), a long pentraxin and a humoral pattern recognition molecule (PRM), has been demonstrated to be protective against Aspergillus fumigatus, an airborne human fungal pathogen. We explored its mode of interaction with A. fumigatus, and the resulting implications in the host immune response. Here, we demonstrate that PTX3 interacts with A. fumigatus in a morphotype-dependent manner: (a) it recognizes germinating conidia through galactosaminogalactan, a surface exposed cell wall polysaccharide of A. fumigatus, (b) in dormant conidia, surface proteins serve as weak PTX3 ligands, and (c) surfactant protein D (SP-D) and the complement proteins C1q and C3b, the other humoral PRMs, enhance the interaction of PTX3 with dormant conidia. SP-D, C3b or C1q opsonized conidia stimulated human primary immune cells to release pro-inflammatory cytokines and chemokines. However, subsequent binding of PTX3 to SP-D, C1q or C3b opsonized conidia significantly decreased the production of pro-inflammatory cytokines/chemokines. PTX3 opsonized germinating conidia also significantly lowered the production of pro-inflammatory cytokines/chemokines while increasing IL-10 (an anti-inflammatory cytokine) released by immune cells when compared to the unopsonized counterpart. Overall, our study demonstrates that PTX3 recognizes A. fumigatus either directly or by interplaying with other humoral PRMs, thereby restraining detrimental inflammation. Moreover, PTX3 levels were significantly higher in the serum of patients with invasive pulmonary aspergillosis (IPA) and COVID-19-associated pulmonary aspergillosis (CAPA), supporting previous observations in IPA patients, and suggesting that it could be a potential panel-biomarker for these pathological conditions caused by A. fumigatus.

Acute pancreatitis (AP) is a common disease caused by a variety of causes. Is uric acid associated with the onset of AP? The objective of this study was to assess whether uric acid concentration in AP patients was higher than that in healthy population, and whether there were associations between uric acid concentration and serological indicators related to AP. A total of 205 AP patients were included in this study. Two hundred and five people who underwent physical examination in our hospital were randomly selected as controls. We analyzed whether there was difference in uric acid concentrations between the two groups. If the difference was statistically significant, the correlations between uric acid concentration and serological indicators in AP patients was further analyzed. There was significant difference in uric acid concentration (P < 0.001) between AP patients and healthy population. Serum uric acid concentration in AP group was significantly higher than that in control group. Two hundred and five AP patients were divided into mild AP group and non-mild AP group. There was no statistically significant difference in uric acid concentration between the two groups (P = 0.176). There was a low linear correlation between serum uric acid concentration and triglyceride level (r = 0.316, P < 0.001). But there was no linear correlation between serum uric acid concentration and hypersensitive C-reactive protein (r = 0.126, P = 0.072), white blood cell (r = 0.192, P = 0.006), albumin (r = 0.183, P = 0.009), total cholesterol concentration (r = 0.133, P = 0.058), fasting blood-glucose (r = 0.133, P = 0.058) and blood calcium (r = 0.155, P = 0.026). Uric acid concentration in patients with AP was significantly higher than healthy population. There was correlation between uric acid concentration and triglyceride in AP patients.

BACKGROUND: The triglyceride-glucose (TyG) index and high-sensitivity C-reactive protein (hsCRP) are the commonly used biomarkers for insulin resistance and systemic inflammation, respectively. We aimed to investigate the combined association of TyG and hsCRP with the major adverse cardiovascular events (MACE) in patients with chronic coronary syndrome (CCS). METHODS: A total of 9421 patients with CCS were included in this study. The primary endpoint was defined as a composite of MACE covering all-cause death, nonfatal myocardial infarction, and revascularization. RESULTS: During the 2-year follow-up period, 660 (7.0%) cases of MACE were recorded. Participants were divided equally into three groups according to TyG levels. Compared with the TyG T1 group, the risk of MACE was significantly higher in the TyG T3 group. It is noteworthy that among patients in the highest tertile of TyG, hsCRP >3 mg/L was significantly associated with an increased risk of MACE, whereas the results were not significant in the medium to low TyG groups. When patients were divided into six groups according to hsCRP and TyG, the Cox regression analysis showed that patients in the TyG T3 and hsCRP >3 mg/L group had a significantly higher risk of MACE than those in the TyG T1 and hsCRP ≤3 mg/L group. However, no significant interaction was found between TyG and hsCRP on the risk of MACE. CONCLUSION: Our study suggests that the concurrent assessment of TyG and hsCRP may be valuable in identifying high-risk populations and guiding management strategies among CCS patients.

Curcumin, derived from turmeric root, exhibits notable anti-inflammatory effects. These anti-inflammatory properties might also provide advantages in reducing cardiovascular complications, such as atherosclerosis. This study aimed to evaluate the efficacy of curcumin in reducing the risk of atherogenesis in obese patients with type 2 diabetes. The study employed a randomized, double-blind, placebo-controlled trial design with 227 participants diagnosed with type 2 diabetes. The parameters used to assess atherogenic risk reduction included pulse wave velocity and metabolic profiles, including low-density lipoprotein cholesterol and small dense low-density lipoprotein cholesterol. Measurements were recorded at baseline and at 3-, 6-, 9-, and 12-month intervals. After 12 months, participants receiving curcumin exhibited a significant reduction in pulse wave velocity (p < 0.001). This group showed significantly reduced levels of cardiometabolic risk biomarkers, including low-density lipoprotein cholesterol and small dense low-density lipoprotein cholesterol, all with p values less than 0.001. High-sensitivity C-reactive protein, interleukin-1 beta, interleukin-6, and tumor necrosis factor-alpha were also significantly lower in the curcumin group, with p values less than 0.001. The curcumin intervention significantly reduced pulse wave velocity and improved cardiometabolic risk profiles. These findings suggest that curcumin treatment may effectively reduce atherogenic risks in type 2 diabetes patients with obesity.

BACKGROUND AND AIMS: Correctly characterizing malnutrition is a challenge. Transthyretin (TTR) rapidly responds to adequate protein intake/infusion, which could be used as a marker to identify malnutrition. Nutritional therapy is used to prevent malnutrition. Parenteral nutrition (PN) requires daily monitoring to determine whether what is being offered is adequate. This article aims to investigate whether the practice of measuring TTR is justified. METHODS: Data from patients admitted to the ward or intensive care unit (ICU) were collected at three different times: within the first 72 h (T1) of PN use, on the 7th day (T2), and the 14th day (T3) after the initial assessment. RESULTS: 302 patients were included; the average age was 48.3 years old; the prevalence of death was 22.2%, and 61.6% of the sample were male. TTR values and the effectiveness of nutritional support in these patients were not associated with the outcome; however, meeting caloric needs was related to the outcome (p = 0.047). No association was found when TTR values were compared to the nutritional status. Thus, TTR was not a good indicator of nutritional risk or nutritional status in hospitalized patients. CONCLUSIONS: Undoubtedly, the TTR measurement was inversely proportional to CRP measurements. It was possible to conclude in this follow-up cohort of hospitalized patients that TTR values were not useful for determining whether the patient was malnourished, predicting death or effectiveness of nutritional support, yet based upon our analyses, a decrease in TTR greater than 0.024 units for every 1 unit increase in CRP might be due to ineffective nutritional supply.

The aim of this study was to assess the relationship of different chronic diseases with immunonutritional markers in the senior population. METHODS: this study included 1190 hospitalized geriatric patients. The criteria to participate were ability to communicate, given consent and C-reactive protein (CRP) lower than 6 mg/dL. RESULTS: the mean age of the study population was 81.7 ± 7.6 years. NLR (neutrophil-to-lymphocyte ratio), LMR (lymphocyte-to-monocyte ratio), MWR (monocyte-to-white blood cell ratio), SII (systemic immune-inflammation index), PNI (prognostic nutritional index) and CAR (C-reactive protein-to-albumin ratio) were related to age. NLR and MWR were higher, while LMR, PLR (platelet-to-lymphocyte ratio and SII were lower in men. All markers were related to BMI. NLR, LMR, LCR (lymphocyte-to-CRP ratio), MWR, PNI and CAR were related to several concomitant chronic diseases. In multivariate analyses, age and BMI were selected as independent predictors of all studied immunonutritional markers. Atrial fibrillation, diabetes mellitus and dementia appear most often in the models. PNI presented the most consistent statistical association with age, BMI and concomitant chronic diseases. CONCLUSIONS: this study reveals the pivotal role of aging and BMI in inflammatory marker levels and the association of immunonutritional markers with different chronic diseases. Atrial fibrillation seems to have the most dominant connection to the immunonutritional markers.
