Background/Objectives: Although systematic reviews and meta-analyses have examined immune-inflammatory indices in cardiovascular disease (CVD), the evidence remains scattered and inconsistent. This umbrella review aims to synthesize findings and evaluate the overall predictive value of these indices for clinical outcomes. Methods: We systematically searched PubMed, Cochrane Library, Web of Science, Embase, Scopus, and Medline for systematic reviews with meta-analyses assessing neutrophil-to-lymphocyte ratio (NLR), systemic immune-inflammation index (SII), platelet-to-lymphocyte ratio (PLR), and systemic inflammation response index (SIRI) in patients with CVD. Study quality and certainty of evidence were appraised using AMSTAR-2 and GRADE, respectively. Results: A total of 35 meta-analyses covering 106 unique outcomes were included, of which 87 showed significant associations. Elevated NLR and SII were consistently linked to higher risks of CVD mortality, major adverse cardiovascular events, myocardial infarction, heart failure, and stroke. PLR and SIRI were primarily associated with poor recovery from stroke and increased mortality in ST-elevation myocardial infarction. Specifically, the methodological quality of the included reviews was generally moderate to high according to AMSTAR-2, whereas none of the associations reached high certainty based on GRADE, with most rated as low or very low and about one-quarter as moderate certainty. Conclusions: The overall certainty of evidence remains limited according to GRADE, alongside methodological heterogeneity, population variability, and inconsistent thresholds that further restrict the direct applicability of these findings in clinical practice. Nevertheless, available evidence indicates that elevated immune-inflammatory indices are likely associated with worse clinical outcomes in patients with CVD. Future research should prioritize establishing standardized cutoffs, improving methodological consistency, and validating these indices across diverse populations to support their integration into clinical risk-stratification frameworks.

Background and Objectives: Systemic inflammation plays a critical role in cancer progression and prognosis. The Systemic Inflammation Response Index (SIRI), a novel marker integrating neutrophil, monocyte, and lymphocyte counts, has been suggested as a prognostic indicator in various malignancies. This study aimed to evaluate the prognostic significance of SIRI in patients with metastatic pancreatic cancer receiving first-line chemotherapy. Materials and Methods: This retrospective study included 147 patients with metastatic pancreatic cancer who received first-line chemotherapy or best supportive care between 2010 and 2024. Clinical and laboratory data were collected from medical records. Overall survival (OS) and progression-free survival (PFS) were assessed using the Kaplan–Meier method, and prognostic factors were identified by univariate and multivariate Cox regression analyses. Results: The median OS and PFS were 7 and 4 months, respectively. Multivariate analysis revealed that ECOG ≥ 2 (HR: 2.094, p = 0.019), liver metastasis (HR: 2.039, p = 0.027), and each unit increase in SIRI (HR: 1.156, p < 0.001) were independent predictors of poorer OS. Patients with SIRI > 1.86 had significantly shorter OS compared to those with SIRI ≤ 1.86 (median OS: 4 vs. 9 months, p = 0.019). Conclusions: SIRI is an independent prognostic marker for survival in metastatic pancreatic cancer patients undergoing first-line and subsequent lines of chemotherapy. These inflammation-based markers are simple, cost-effective tools that could be integrated into routine clinical practice to aid in risk assessment and treatment planning. Full article

Chromosome 6q deletion syndrome is a rare entity that has a highly variable clinical presentation and size of deletions. The most frequent manifestations of 6q terminal deletion are intellectual disability, facial dysmorphism, brain structural anomalies, and congenital heart defects. The phenotype is not clinically recognizable, except in those who harbor a terminal 6q deletion that includes the ARID1B gene, in whom features similar to Coffin–Siris syndrome (CSS) can be observed. We report the case of a female newborn with a prenatal diagnosis of a terminal deletion on 6q25.1q27, which encompasses the ARID1B gene, and who was diagnosed with CSS during the neonatal period. From our review, we found that facial gestalt, hypertrichosis, and fifth fingernail aplasia/hypoplasia, along with other features, such as vertebral defects and cystic hygroma (or webbed neck), correlated with the presence of a CSS causally related to 6q25.3 small deletions that include the ARID1B gene.

Introduction: It is unclear which patients with testicular cancer (TC) experience a higher incidence of bleomycin-induced pulmonary toxicity. Objective: The aim of this study was to analyze the prognostic significance of lymphocyte-associated inflammation markers that may predict bleomycin-related pulmonary toxicity in TC. Results: Clinical and laboratory data were recorded for 118 patients diagnosed with TC who received bleomycin, with a median age at diagnosis of 32.19 ± 9.62. Symptomatic pulmonary toxicity was present in 19.49% (n = 23) of patients. Of these, 66.67% had a DLCO decrease of more than 10%. When comparing patients with and without pulmonary toxicity, there were no differences in terms of age at diagnosis, performance status, histopathological subgroup, tumor size, lymphovascular invasion, diagnostic symptom, stage, number of adjuvant treatment cycles, and tumor marker levels. Patients with pulmonary toxicity were more likely to be active smokers than those without pulmonary toxicity, and NLR > 1.64, PLR > 93.92, CLR > 0.49, SII > 444.25, and SIRI > 0.66 were found to be statistically significant. Lymphocyte-related inflammation markers (NLR, PLR, LMR, CLR, SII, and SIRI) were found to be prognostic for pulmonary toxicity. There was 5.2 times more pulmonary toxicity in smokers than in non-smokers. The prognostic inflammation markers that enable us to predict pulmonary toxicity are TC. Conclusions: The employment of lymphocyte-related inflammation biomarkers at the commencement of treatment offers a means of predicting bleomycin-related pulmonary toxicity in TC. Full article

Background: The change over time of certain inflammatory markers, such as the neutrophil–lymphocyte ratio (NLR) and systemic inflammatory response index (SIRI), is a prognostic factor in many cancers, including breast cancer. This study retrospectively evaluated how a 12-week intensive exercise program might have influenced both the NLR and SIRI in women with breast cancer. Methods: Two institutional review board-approved prospective clinical trials, EXERT-BC (NCT05747209, 2 November 2022) and EXERT-BCN (NCT05978960, 31 July 2023), were retrospectively assessed. Complete blood count (CBC) values performed before and after participation in a 12-week intensive resistance program were analyzed post hoc. Blood tests were ordered as part of routine clinical care and not pre-specified by either study protocol. Participants who had blood work more than four months from study intake or completion were excluded. Additionally, those undergoing active systemic therapy or with underlying inflammatory conditions were also excluded. The NLR and SIRI values were analyzed via the Mann–Whitney test, with pair-wise assessment of pre- and post-intervention values via the Wilcoxon signed-rank test. Results: Out of 84 participants, 21 people met the inclusion criteria. Roughly 70% had either ductal carcinoma in situ (DCIS) or early-stage breast cancer. The average blood draw was taken within two months of study intake and outtake. After the 12-week structured exercise program, there was an associated reduction in both the NLR (2.26 [IQR, 1.70–4.22] to 1.99 [1.44–2.62]; ΔNLR = −0.27, W = 47.0, p = 0.016) and SIRI (1.23 [0.82–1.64] to 0.80 [0.59–1.45]; ΔSIRI = −0.43, W = 48.0, p = 0.018). Of those who saw their inflammatory markers improve, roughly two thirds showed a clinically relevant improvement. Conclusions: Completion of a 12-week intensive resistance exercise program was associated with a statistically improved NLR and SIRI. The small sample size and retrospective nature limit the broader application of these findings. The results, however, provide a genesis for prospective validation examining the potential benefit exercise might have on the NLR and SIRI in women with breast cancer. Full article

Background: Pancreatic ductal adenocarcinoma (PDAC) remains one of the deadliest cancers, largely due to late diagnosis and the lack of reliable non-invasive biomarkers. Altered trace element homeostasis has been implicated in tumor biology and systemic inflammation, but comprehensive metallomic profiling in PDAC is still limited. Methods: Using inductively coupled plasma mass spectrometry (ICP-MS), we quantified 20 serum and 15 urinary metals in 71 PDAC patients and 69 matched controls. Statistical analyses included univariate Wilcoxon testing, correlation with systemic inflammatory indices (NLR, MLR, SIRI, AISI, HGB/RDW, PCT), and multivariate chemometric modeling (PCA-LDA). K-means clustering was applied to identify patient subgroups with distinct biochemical signatures. Results: PDAC patients showed significantly elevated urinary antimony, chromium, cadmium, and vanadium, whereas controls exhibited higher serum selenium, zinc, barium, vanadium, and cobalt (all p < 10⁻⁵). The PCA-LDA model achieved 99% classification accuracy (Monte Carlo cross-validation, 1000 iterations), highlighting complementary diagnostic contributions of serum and urinary profiles. Serum selenium was inversely associated with SIRI and NLR, while urinary cobalt correlated positively with NLR. Clustering revealed three PDAC subgroups with different inflammatory and metallomic patterns, suggesting underlying biological heterogeneity. Conclusions: PDAC is characterized by opposite serum-urine metal signatures, indicating altered absorption-excretion dynamics. Selenium depletion may represent a protective biomarker, whereas urinary cobalt excretion reflects systemic inflammation. This integrative ICP-MS–chemometric approach provides a promising diagnostic tool for improving early detection and patient stratification in clinical practice. Full article

Background: Endometrial cancer (EC) is the most common gynecological malignancy in developed countries. While early-stage disease has favorable outcomes, advanced or recurrent EC remains associated with poor prognosis. Novel prognostic markers are needed to refine risk stratification. Systemic inflammation-based indices such as Pan-Immune Inflammation Value (PIV), Systemic Inflammation Response Index (SIRI), and Systemic Immune Inflammation Index (SII) have shown prognostic potential in solid tumors. Methods: We retrospectively evaluated 78 patients with endometrioid EC who had undergone hysterectomy with adnexectomy and lymphadenectomy. Demographic, clinicopathological, and laboratory data were extracted from electronic medical records. PIV, SII, and SIRI were calculated from the preoperative complete blood counts. Survival was assessed using Kaplan–Meier analysis, while prognostic factors were determined using univariate and multivariate Cox regression analyses. Results: The median age was 59 years, and 64.1% of the patients presented with early-stage disease. A high PIV (≥802) was significantly associated with a shorter overall survival (64 vs. 111 months, p < 0.001). PIV demonstrated the highest discriminatory accuracy (AUC = 0.776), followed by the SII (0.747) and SIRI (0.718). Univariate analysis identified that age, grade, LVSI, PNI, stage, distant metastasis, and high PIV, SII, SIRI, and NLR were predictors of poor survival. Multivariate analysis confirmed grade, distant metastasis and SIRI ≥ 1.5 as independent prognostic factors. Conclusions: Inflammation-based indices, particularly PIV and SIRI, correlated with survival outcomes in patients with EC. The SIRI retained an independent prognostic value, whereas PIV showed a strong discriminatory capacity. Incorporating these indices into established risk models may improve prognostic precision and support individualized management. Full article

Objectives: Gestational diabetes mellitus (GDM), particularly when combined with overweight or obesity, is associated with adverse neonatal outcomes such as high birth weight and increased adiposity. We determined the effect of a preconception lifestyle intervention initiated before and continued throughout pregnancy on neonatal, birth-related, and body composition outcomes at birth and 6–8 weeks of age in children of participants in the BEFORE THE BEGINNING randomized controlled trial. Methods: People (N = 167) at increased risk of GDM and planning pregnancy were randomly allocated 1:1 to intervention or control. The intervention included time-restricted eating and exercise training. Time-restricted eating involved consuming all energy within ≤10 h/day, ≥5 days per week, and the amount of exercise was set using a heart rate-based physical activity metric (Personal Activity Intelligence, PAI), with the goal of ≥100 weekly PAI points. The main outcome of interest in this report was the proportion of infants with birth weight > 4.0 kg. Results: Among 106 live births, 21% (11/53) of infants in the intervention group and 28% (15/53) in the control group had birth weight > 4 kg (p = 0.367). Mean birth weight did not differ significantly between groups (mean difference −159.3 g, 95% confidence interval −375.7 to 57.2, p = 0.148). No significant between-group differences were found for additional neonatal, birth-related, or early postnatal body composition outcomes. Conclusions: In this secondary analysis, we found no evidence of effects of a preconception lifestyle intervention on the risk of macrosomia or neonatal body composition. Full article

Background/Objectives: Hashimoto’s thyroiditis-induced hypothyroidism (HT–HypoT) is frequently accompanied by ocular surface complaints, but the role of systemic inflammatory markers in dry eye disease (DED) among these patients remains unclear. This study aimed to evaluate the relationship between composite inflammatory indices and the presence and severity of DED in patients with HT–HypoT. Methods: This retrospective study included 86 HT–HypoT patients and 43 DED controls without systemic comorbidities. DED diagnosis and severity were assessed using the Ocular Surface Disease Index (OSDI) and objective ocular surface tests. Laboratory parameters and composite inflammatory indices—including neutrophil-to-lymphocyte ratio (NLR), platelet-to-lymphocyte ratio (PLR), systemic immune-inflammation index (SII), systemic inflammation response index (SIRI), C-reactive protein-to-albumin ratio (CAR), and prognostic nutritional index (PNI)—were compared between groups. Results: DED was present in 44% of HT–HypoT patients. SIRI and CAR were higher in HT–HypoT patients with DED and increased with severity. Both indices independently predicted the presence and severity of DED and exhibited higher diagnostic performance than other inflammatory indices. Conclusions: In patients with HT–HypoT, SIRI and CAR provide additional diagnostic value for identifying the presence and severity of DED beyond that offered by traditional markers. These findings highlight the potential utility of routine blood-derived indices as adjunctive biomarkers in thyroid-related DED. Full article

Objective: To assess the predictive value of systemic inflammatory markers for postoperative complications in older adults undergoing posterior spinal instrumentation for either lumbar spinal stenosis (LSS) or osteoporotic vertebral fractures (OVFs). This study design as a retrospective observational study. Methods: Fifty-four patients aged ≥ 55 years who underwent posterior spinal instrumentation between 2020 and 2023 were retrospectively analyzed. Patients were grouped into LSS (n = 27) and OVF (n = 27) cohorts. Preoperative, early postoperative, and 6-month follow-up systemic inflammatory marker levels, including the Systemic Inflammatory Response Index (SIRI), Systemic Immune-Inflammation Index (SII), Neutrophil-to-Lymphocyte Ratio (NLR), Platelet-to-Lymphocyte Ratio (PLR), and Monocyte-to-Lymphocyte Ratio (MLR), were recorded. The primary outcome was the occurrence of postoperative infectious complications. ROC curve analysis was conducted to evaluate the discriminatory power of each marker. Results: SIRI values were significantly higher in the OVF group than in the LSS group at all time points (p < 0.05). Postoperative complications occurred in 7.4% of patients, equally distributed between groups. ROC analysis showed that preoperative SIRI had the highest predictive value (AUC = 0.743), with a cutoff value of 2.69 yielding 100% sensitivity and 65.3% specificity. Other indices showed poor predictive accuracy (AUC < 0.70). Conclusions: Preoperative SIRI is a promising, easily obtainable biomarker for identifying older patients at higher risk of postoperative complications following posterior spinal instrumentation. Its implementation may improve preoperative risk stratification in spine surgery. Full article

Background/Objectives: This study aimed to evaluate the relationship between maternal systemic inflammatory indices, hematological parameters, and fetal thymus size, as measured by the thymus–thoracic ratio (TTR), among diabetic pregnancies, and to establish predictive cut-off values for reduced thymus size. Methods: This prospective cohort study enrolled 532 pregnant women, divided into four groups: pregestational diabetes mellitus (PGDM, n = 44), diet-controlled gestational diabetes mellitus (GDM, n = 73), insulin-treated GDM (n = 49), and normoglycemic controls (n = 366). Fetal thymus size, alongside serum levels of neutrophil-to-lymphocyte ratio (NLR), platelet-to-lymphocyte ratio (PLR), systemic immune-inflammation index (SII), systemic inflammation response index (SIRI), aggregate index of systemic inflammation (AISI), fibrinogen-to-albumin ratio (FAR), and C-reactive protein (CRP)-to-albumin ratio, were assessed in the third trimester. Results: All maternal diabetes subgroups demonstrated significantly reduced fetal thymus size compared with controls, with the most pronounced reduction observed in the PGDM group (p < 0.001). NLR, PLR, MLR, SIRI, AISI, and MPV were significantly elevated in the PGDM cohort, whereas CAR, FAR, and fibrinogen levels were markedly increased in the insulin-treated GDM group. Albumin levels were significantly decreased in both the PGDM and the insulin-treated GDM groups (p < 0.001). Among the evaluated biomarkers, AISI and FAR exhibited the highest diagnostic accuracy for predicting reduced fetal thymus size, with optimal cut-off values of 640.3 (sensitivity 82.3%, specificity 86.7%) and 0.114 (sensitivity 74.3%, specificity 88.7%), respectively. Conclusions: Maternal systemic inflammatory burden, as indicated by hematological biomarkers, is significantly associated with reduced fetal thymic size in diabetic pregnancies. These findings suggest that readily accessible blood-derived biomarkers, particularly AISI and FAR, may complement ultrasonographic evaluation, offering a cost-effective, non-invasive approach to predict compromised fetal immune development, especially in settings where direct thymic imaging is impractical.

Objective: The aim of this study was to evaluate whether Hemoglobin, Albumin, Lymphocyte, and Platelet (HALP) scores, the Systemic Immune-Inflammation Index (SII), and the Systemic Inflammatory Response Index (SIRI) can predict intensive care unit (ICU) or inpatient admissions in pediatric diabetic ketoacidosis (DKA) cases and to determine their sensitivity and specificity. Methods: This retrospective study included 39 pediatric patients (<18 years) diagnosed with DKA (pH < 7.3, HCO₃ < 15). HALP, SII, SIRI, and urine ketone values were collected from medical records. Statistical analyses included ROC curve analysis, correlation tests, and appropriate parametric or non-parametric comparisons to evaluate associations with 30-day outcomes. Results: The median age was 13 years (IQR: 8–15), 56.4% were male, and 64.1% required ICU monitoring. ICU patients had significantly lower pH (p = 0.005) and HCO₃ (p = 0.012) and significantly higher monocyte, SII, and SIRI values (all p ≤ 0.018). ROC analysis showed SIRI had the highest predictive power for ICU admission (cut-off: 3911; sensitivity: 76%; specificity: 85.7%), followed by SII. HALP scores did not demonstrate any value in assessingdisease severity for predicting ICU admission (AUC = 0.25). Conclusion: SIRI and SII are reliable predictors of ICU admission in pediatric DKA. HALP scores do not predict ICU admission and should not be considered a marker of disease severity. Incorporating SIRI and SII into clinical decision-making may improve early risk stratification. Prospective multicenter studies are warranted to validate these results. Full article

As semiconductor technologies advance, SRAM cells deployed in space systems face heightened sensitivity to radiation-induced soft errors. In conventional 6T SRAM, when high-energy particles strike sensitive nodes, single-event upsets (SEUs) may occur, flipping stored bits. Furthermore, with aggressive scaling, charge sharing among adjacent devices can trigger single-event multi-node upsets (SEMNU). To address these reliability concerns, this study presents a radiation-hardened SRAM design, SHWA18T, tailored for space applications. The proposed architecture is evaluated against IASE16T, PRO14T, PRO16T, QCCS, SIRI, and SEA14T. Simulation analysis demonstrates that SHWA18T achieves improved performance, particularly in terms of critical charge and write capability. The design was implemented in 90 nm CMOS technology at a 1 V supply. With enhanced robustness, the cell withstands both SEUs and SEMNUs, thereby guaranteeing stable data retention in space environments. Full article

Postimplantation syndrome (PIS) is an early inflammatory response following endovascular stent-graft implantation (EVAR and TEVAR), defined by culture-negative fever and leukocytosis. The patient’s preoperative inflammatory status is thought to play a central role in its development. This study aimed to evaluate whether the systemic inflammatory response index (SIRI) and the eosinophil-to-lymphocyte ratio (ELR) can serve as preoperative predictors of PIS. Clinical data from 300 patients who underwent aortic endograft implantation and laboratory results obtained 24 h before the procedure, and at 24 h, 72 h, and 1 week postoperatively, were prospectively recorded. PIS was defined as culture-negative fever ≥ 37.8 °C accompanied by leukocytosis ≥ 12,000/µL. Inflammation-based indices derived from complete blood count (SIRI and ELR), along with serum C-reactive protein (CRP) and albumin levels, were compared between patients with and without PIS. Logistic regression and receiver operating characteristic (ROC) analyses were performed to identify independent predictors. PIS developed in 55 patients (18.3%). Patients with PIS were younger (70.1 ± 8.6 vs. 72.7 ± 7.3 years; p = 0.042) and had larger aneurysm diameters and greater mural thrombus thickness. Preoperatively, leukocyte count, SIRI, and CRP levels were significantly higher in patients who developed PIS, whereas ELR and albumin levels were lower. Multivariable analysis showed that a larger aneurysm diameter (OR: 1.2; 95% CI: 1.0–1.3; p = 0.003), greater mural thrombus thickness (OR: 1.3; 95% CI: 1.0–1.6; p = 0.012), EVAR procedure (OR: 3.7; 95% CI: 1.2–6.3; p = 0.033), elevated SIRI (OR: 1.9; 95% CI: 1.2–3.1; p = 0.005), and higher CRP (OR: 1.4; 95% CI: 1.1–3.2; p = 0.003) were significantly associated with PIS. In contrast, increasing age, higher ELR, and higher albumin levels were associated with a reduced risk of PIS. Simple biomarkers routinely obtained from standard laboratory tests can contribute meaningfully to the preoperative prediction and postoperative identification of PIS. Their integration into risk stratification models and confirmation against definitive diagnostic criteria will require validation in larger, multicenter studies. Full article

Background/Objectives: This cross-sectional study aimed to identify predictors of parent-reported health-related quality of life (HRQOL) in young children with early brain damage and severe motor dysfunction. It used baseline data from the PIH Multi Study, a randomized controlled trial evaluating an intensive, family-centered habilitation program for preschool children and their parents. Methods: Parent-reported HRQOL were measured using the CPCHILD questionnaire. Potential predictors included adaptive function (PEDI-CAT), gross motor function (GMFM-66), postural control and balance (ECAB), and communication function (FOCUS). These were selected to reflect the domains of the ICF-CY framework. Data were collected by professionals and by parents. Linear regression analyses were conducted to identify significant predictors. Results: Analyses included 65 children. Better adaptive skills, gross motor function, postural control, and communication all predicted higher parent-reported HRQOL. Adaptive skills—particularly in self-care and mobility—and gross motor function emerged as the strongest predictors. Conclusions: The study highlights the importance of targeting basic functional skills in early habilitation efforts for children with severe disabilities. The findings support a multidimensional understanding of health in line with the ICF-CY framework and underline the value of early, individualized, and family-centered interventions. Future research should investigate these predictors longitudinally and explore ways to integrate children’s own perspectives in assessment of HRQOL. Full article
