Background and Objectives: Prognostic assessments in grade 4 diffuse astrocytic tumors primarily depend on clinical and molecular characteristics, with radiological attributes frequently assessed in isolation. In this study, we explored whether an integrated radiological approach combining tumor burden, anatomical spread, and mass effect could contribute to survival prediction. Materials and Methods: A total of 310 adult patients with histopathologically confirmed grade 4 diffuse astrocytic tumors, diagnosed between January 2022 and January 2025, were included in this retrospective single-center cohort. Preoperative MRI was used to assess contrast-enhancing tumor volume, edema volume, and brain volume, combined with anatomical spread and midline shift as a marker of mass effect. Tumor burden was defined as the ratio of enhancing tumor volume to brain volume (ETV/BV). Overall survival was analyzed using Kaplan–Meier and Cox regression methods. Model performance was evaluated with the C-index, bootstrap internal validation, and 12-month calibration. Results: Tumor burden was higher in IDH-wildtype tumors, which also showed higher midline shift and more frequent deep structure involvement and contralateral extension. In multivariable analysis, IDH status, age, tumor burden, midline shift, and deep structure involvement were independently associated with overall survival. A greater tumor burden was associated with reduced survival. The addition of molecular and imaging-derived variables improved discrimination, increasing the C-index from 0.69 to 0.76. Following bootstrap validation, the corrected value was 0.73. Calibration at 12 months demonstrated acceptable agreement between predicted and observed outcomes. Conclusions: An integrated radiological approach that combines tumor burden, anatomical spread, and mass effect may support prognostic assessment in addition to established clinical and molecular variables.

Objective: To identify clinical and neuroimaging predictors of atypical Posterior Reversible Encephalopathy Syndrome (PRES) in eclampsia and evaluate the role of multi-regional cerebral involvement (neuroimaging burden). Methods: This retrospective cohort study included 266 patients with eclampsia and radiologically confirmed PRES (2018–2025). Patients were classified as typical (n = 234, 88.0%) or atypical (n = 32, 12.0%). A two-stage multivariable logistic regression was performed to identify independent predictors, sequentially incorporating clinical and neuroimaging variables. Results: Peak systolic blood pressure was significantly higher in atypical vs. typical groups (191.6 ± 20.4 vs. 172.4 ± 18.5 mmHg, p < 0.001). Furthermore, atypical cases exhibited a significantly higher systemic inflammatory burden, characterized by markedly elevated Systemic Immune-Inflammation Index (SII) and CRP levels (p < 0.001). Atypical cases exhibited a markedly greater neuroimaging burden, with a higher mean number of involved brain regions (4.4 ± 1.2 vs. 2.1 ± 0.6, p < 0.001). In Model 1 (clinical variables only), systolic blood pressure was a strong predictor of atypicality (OR: 1.24 per 10 mmHg increase, 95% CI: 1.12–1.38, p < 0.001). After incorporating neuroimaging features in Model 2, the total number of involved brain regions emerged as the strongest independent predictor (OR: 2.08, 95% CI: 1.52–2.85, p < 0.001), while the independent effect of blood pressure was attenuated. Conclusions: Atypical PRES in eclampsia reflects extensive, high-burden cerebral vasogenic edema rather than a distinct radiological subtype. While hypertension initiates the process, the total regional burden determines the atypical signature. This burden-focused perspective improves risk stratification and diagnostic vigilance in high-risk obstetrics. Full article

Objectives: The aim of this study was to analyze the association between cardiovascular risk factors such as glycated hemoglobin (HbA1c), low-density lipoprotein cholesterol (LDL-C), hypertension, overweight, and smoking and longitudinal anatomical and functional changes in diabetic macular edema (DME) during intravitreal therapy. Materials and Methods: This is a retrospective, observational, descriptive study conducted on a sample of 318 patients with DME associated with some degree of diabetic retinopathy (DR). They were treated with aflibercept, ranibizumab, and/or dexamethasone, assessing anatomical and functional outcomes through visual acuity, retinal thickness, and macular volume. Simultaneously, serum HbA1c and LDL-C levels, blood pressure, body mass index (BMI) and tobacco use were measured at baseline, 6, and 12 months to determine their association with treatment response using linear mixed models. Results: Of the variables analyzed in this study, HbA1c and degree of retinopathy were significantly associated with greater retinal thickness over time. Likewise, we found that, compared with aflibercept, dexamethasone intravitreal treatment was associated with greater retinal thickness over time. Concerning visual acuity, we found an inverse relationship with age, tobacco use and degree of retinopathy. Associations between outcomes and the initial intravitreal agent were observed; however, these findings should be interpreted cautiously. Conclusions: This study was consistent with previous research suggesting an association between glycemic control and DME response and progression. It also highlighted the importance of degree of retinopathy and intravitreal treatment in diabetic macular edema progression. Treatment-related findings represent exploratory associations and should not be interpreted as evidence of comparative effectiveness. Full article

Background: Extrinsic compression of the left atrium (LA) is a rare and underrecognized condition that may result in significant hemodynamic compromise and atrial arrhythmias. The available evidence has been largely limited to isolated case reports and small case series, and clinical awareness has remained low. Methods: We performed a structured review of published case reports and case series indexed in PubMed between 2016 and 2026 describing extracardiac LA compression. A predefined and reproducible literature search strategy with explicit eligibility criteria was applied. The structured review included 22 publications reporting 23 individual cases of LA compression; in addition, two institutional cases with distinct etiologies were presented separately. Demographic characteristics, presenting symptoms, diagnostic modalities, complications, management strategies, and outcomes were synthesized descriptively. Results: The structured review identified gastroesophageal disorders, particularly hiatal hernia, as the most frequent etiology, followed by vascular, mediastinal, malignant, and musculoskeletal causes. Dyspnea was the most common presenting symptom, while hemodynamic compromise, pulmonary edema, and atrial arrhythmia represented the most frequent complications. Transthoracic echocardiography was the initial diagnostic modality in all reported cases, with computed tomography required for definitive etiological diagnosis. The two institutional cases illustrated both a common cause, hiatal hernia mimicking intracardiac mass, and a rare, aggressive malignant cause with extensive mediastinal involvement. Conclusions: Extrinsic LA compression arises from diverse extracardiac pathologies and may be clinically severe. Transthoracic echocardiography can serve as a pivotal first-line tool for early recognition and differentiation from intracardiac masses, while cross-sectional imaging is essential for etiological clarification. By integrating institutional experience with a structured synthesis of published cases, this review can provide practical insights to support timely diagnosis and management of this potentially life-threatening condition.

Background and Clinical Significance: Decompressive hemicraniectomy (DHC) is a life-saving intervention for malignant middle cerebral artery (MCA) infarction, but postoperative secondary injury mechanisms and functional outcome remain difficult to evaluate using intracranial pressure (ICP) alone. The pressure reactivity index (PRx), calculated as the moving correlation coefficient between ICP and mean arterial pressure (MAP), provides a measure of cerebral autoregulation. The utility of PRx monitoring in ischemic stroke, especially following DHC, remains uncertain. Case Presentation: We describe two patients presenting with acute ischemic stroke in the MCA territory who underwent DHC followed by postoperative ICP and PRx monitoring. Case 1 is a 40-year-old female with a left proximal MCA occlusion initially treated with endovascular thrombectomy (EVT) who required emergent DHC due to re-occlusion. Postoperatively, ICPs remained controlled, and PRx values were favorable (<0.2), indicating preserved cerebral autoregulation. She later showed moderate neurological improvement. Case 2 was a 68-year-old female with a left proximal MCA occlusion treated with EVT who developed worsening cerebral edema and midline shift, necessitating emergent DHC. Despite adequate ICP control, PRx values remained markedly elevated (0.45 to 0.73), consistent with impaired cerebral autoregulation, and her neurologic state remained poor at discharge. Conclusions: These contrasting cases suggest that PRx may provide physiologic information not reflected by ICP metrics alone post-DHC. PRx monitoring may provide complementary physiologic insight into postoperative autoregulatory status following DHC. Further investigation is warranted to define its role in individualized post-DHC management and prognostication in malignant ischemic stroke. Full article

Background/Objectives: Ventricular enlargement is a common finding on non-contrast computed tomography (CT) in acute neurological presentations, occurring in hydrocephalus, stroke, and traumatic brain injury. This study evaluated whether routinely available CT-based ventricular morphometric parameters can distinguish hydrocephalus from stroke and traumatic brain injury using initial imaging examinations. Methods: This retrospective observational study included 186 adults (68 with hydrocephalus, 64 with stroke, and 54 with TBI) who underwent index non-contrast cranial CT. Quantitative ventricular parameters included Evans index and third ventricle width, alongside temporal horn dilation and periventricular edema. Multivariable logistic regression models were developed to assess diagnostic performance. A primary morphometric model and a distortion-controlled model incorporating midline shift, mass lesions, and hemorrhage burden were analyzed. Discrimination was evaluated using receiver operating characteristic (ROC) curves. Results: Patients with hydrocephalus showed significantly greater ventricular enlargement, with higher Evans index and third ventricle width compared with stroke and traumatic brain injury groups. The primary model demonstrated moderate discrimination (AUC 0.71). After adjustment for intracranial distortion variables, model performance improved substantially (AUC 0.91), with balanced sensitivity and specificity at optimized thresholds. Evans index and third ventricle width were the strongest independent predictors. Conclusions: CT-derived ventricular morphometrics provide a practical and reproducible approach for differentiating hydrocephalus from stroke and traumatic brain injury on first-presentation CT, supporting objective interpretation in routine neuroimaging practice.

Background: Accurate perioperative cardiovascular risk stratification remains challenging in patients undergoing noncardiac surgery. Although treadmill testing (TMT) is widely used for functional assessment, its ability to identify truly high-risk patients is limited. Natriuretic peptides reflect integrated myocardial stress and may provide complementary prognostic information, particularly in patients with abnormal functional test results. Methods: In this prospective multicenter observational study, 178 patients with at least one Revised Cardiac Risk Index risk factor undergoing noncardiac surgery were included. All patients underwent preoperative TMT and had available N-terminal pro–B-type natriuretic peptide (NT-proBNP) measurements. The primary endpoint was 30-day major adverse cardiac events (MACE), defined as a composite of cardiac death, nonfatal myocardial infarction, myocardial injury after noncardiac surgery, pulmonary edema with heart failure, and clinically significant arrhythmias. Incremental prognostic value was assessed using the area under the receiver operating characteristic curve (AUC), net reclassification improvement (NRI), and integrated discrimination improvement (IDI), with internal validation using bootstrap resampling. Results: At 30 days, 26 patients (14.6%) experienced MACE, of whom seven experienced more than one event. Log-transformed NT-proBNP was independently associated with perioperative events in parsimonious multivariable models. Elevated NT-proBNP, particularly NT-proBNP ≥ 1000 pg/mL, was independently associated with perioperative events after multivariable adjustment. Importantly, the incremental prognostic value of NT-proBNP was most pronounced in patients with a positive TMT, in whom NT-proBNP improved risk discrimination (ΔAUC = +0.09) and reclassification (NRI = 1.00). In contrast, among patients with a negative TMT, the additional prognostic contribution of NT-proBNP was modest and not statistically significant. Subgroup findings should be interpreted cautiously, given the limited number of events. Conclusions: Preoperative NT-proBNP provides modest but independent incremental prognostic value beyond treadmill testing, with the greatest impact observed in patients with positive TMT results. Although improvements in discrimination were moderate, NT-proBNP may help refine perioperative risk assessment in selected intermediate- to high-risk patients. These findings support a complementary biomarker-based approach to MACE. Full article

Background: The aim of this study was to comprehensively investigate the potential degenerative effects of periodontitis severity on retinal and choroidal structures in patients with different types of diabetic retinopathy (DR). Materials and Methods: The study’s Clinical Trials Registration Number is NCT07137013. A total of 100 participants (56 females and 44 males), each group consisting of 20 individuals, were allocated into five groups: systemically healthy controls (G1), diabetic patients without DR (G2: DM+ DR−), non-proliferative DR without diabetic macular edema (G3: NPDR DME−), non-proliferative DR with diabetic macular edema (G4: NPDR DME+), and proliferative DR (G5: PDR). Ocular examinations were performed using optical coherence tomography (OCT) and OCT angiography (OCTA). Retinal layer thicknesses, choroid-sclera interface (CSI), ganglion cell layer (GCL), retinal nerve fiber layer (RNFL), and peripapillary CSI were assessed by OCT, whereas superficial and deep retinal vessel densities and the foveal avascular zone (FAZ) were evaluated by OCTA. Clinical periodontal status was assessed using plaque index (PI), gingival index (GI), bleeding on probing (BOP), probing pocket depth (PPD), and clinical attachment loss (CAL). Results: In the G3 and G5 groups, the presence of stage III–IV periodontitis was associated with a marked increase in retinal layer thickness. GCL + Inner Plexiform Layer (GCL+) thickness was significantly reduced in individuals with stage III–IV periodontitis in almost all regions of the G5 group, except for the 3 mm nasal and inferior areas. Peripapillary CSI values showed a significant decrease with increasing periodontitis severity. RNFL thickness was significantly reduced in individuals with stage III–IV periodontitis, particularly in the G5 group. OCTA analyses demonstrated significant reductions in superficial and deep retinal vessel densities in several regions in the presence of stage III–IV periodontitis. Moreover, FAZ areas were significantly enlarged in individuals with stage III–IV periodontitis in the G2 and G5 groups. Conclusions: Periodontal inflammation, particularly in advanced periodontitis (stage III–IV), induces degenerative changes in the retinal microvasculature and neural tissues. Increasing periodontitis severity may represent a potential provoking factor in the pathogenesis of DR. Full article

Background/Objectives: Diagnostic evaluation and management of nontraumatic osteonecrosis of the femoral head (ONFH) vary substantially. This systematic review was conducted to inform development of the Association Research Circulation Osseous (ARCO) clinical practice guideline for diagnosis and treatment of ARCO stages I to III ONFH. Methods: We searched MEDLINE, EMBASE, Web of Science, SCOPUS, Global Index Medicus, and the Cochrane Library for studies evaluating imaging modalities and treatments for adult ONFH. We assessed risk of bias using the QUADAS-2, the ROB-2, and the ROBINS-I tools; conducted meta-analyses using random-effects regression; and evaluated certainty of evidence using GRADE methodology. Results: Among 36 included studies, 18 addressed diagnostic test accuracy and 18 addressed comparative effectiveness of treatments. Magnetic resonance imaging (MRI) demonstrated the highest pooled sensitivity (0.91; 95% confidence interval (CI), 0.87 to 0.94) and specificity (0.96; 95% CI, 0.87 to 0.99) for ONFH diagnosis. Bone marrow edema and grade 2+ joint effusion on MRI differentiated symptomatic versus asymptomatic disease. Computed tomography and MRI better detected subchondral fractures than plain radiography. Very low-grade evidence suggested lower rates of femoral head collapse with core decompression plus bone marrow concentrate compared with core decompression alone (pooled relative risk [RR], 0.55; 95% CI, 0.36 to 0.83), and with vascularized versus non-vascularized bone grafting (RR, 0.35; 95% CI, 0.14 to 0.84) over a ≤5-year follow-up. Based on three non-comparative case series, osteotomies might have a lower risk of collapse over a 10- to 20-year follow-up, but this needs to be evaluated in future comparative research. Inconsistent outcome reporting hindered treatment outcome pooling. There were no comparative studies that evaluated observation only versus intervention in asymptomatic disease or strategies for monitoring treatment response. Conclusions: Evidence supporting optimal imaging modalities and early joint-preserving interventions remains limited and predominantly observational, underscoring the need for high-quality comparative studies with consistently defined core outcomes to guide clinical decision-making.

Background and Object: Complex Regional Pain Syndrome Type I (CRPS-I) is a debilitating condition often triggered by trauma, with early pathophysiology driven by neuroinflammation and oxidative stress. Avocado/soybean unsaponifiables (ASU) possess potent anti-inflammatory and antioxidant properties but have never been tested for CRPS-I prevention. This study investigated the preventive effects of early systemic administration of ASU on the development of CRPS-I-like features in a validated rat model of tibial fracture and cast immobilization. Methods: Twenty adult male Wistar rats were randomized into two groups (n = 10/group): a CRPS-I (Vehicle) group receiving daily intraperitoneal saline, and a CRPS-I+ASU group receiving daily ASU (300 mg/kg/day). The model was induced via a right tibial fracture followed by 28 days of cast immobilization. Treatment began immediately post-fracture. Behavioral outcomes (mechanical allodynia via von Frey, paw edema, temperature asymmetry) were assessed pre-fracture and on day 29. Subsequently, levels of pro-inflammatory cytokines (IL-1β, IL-6, TNF-α) and oxidative stress markers (TAS, TOS, OSI) were measured in the ipsilateral hind paw tissue. Results: ASU treatment significantly attenuated the development of CRPS-I-like manifestations. Compared to the vehicle group, the ASU group exhibited a markedly lower median percentage decrease in mechanical withdrawal threshold (30.20% [22.56–37.01] vs. 51.45% [47.84–61.11], p = 0.001), reduced temperature asymmetry (0.75 °C [0.55–1.00] vs. 1.95 °C [1.80–2.33], p < 0.001), and less paw edema (8.35% [7.06–11.29] vs. 14.75% [12.66–19.20], p = 0.004). Biochemically, ASU treatment significantly suppressed tissue levels of IL-1β, IL-6, and TNF-α (all p < 0.001), enhanced total antioxidant status (TAS), and reduced total oxidant status (TOS) and the oxidative stress index (OSI) (all p < 0.001). Conclusions: Early systemic administration of ASU significantly prevents the development of nociceptive, vascular, inflammatory, and oxidative disturbances in a rat model of CRPS-I. These findings highlight ASU’s multimodal protective effects at the tissue level and position it as a promising candidate for early preventive intervention in post-traumatic CRPS-I. Full article

Background: This study aimed to investigate the association between femoroacetabular impingement (FAI) morphology and femoral head bone marrow edema of unknown etiology on hip magnetic resonance imaging (MRI), and to assess the added value of computed tomography-based three-dimensional maximum intensity projection (CT-MIP) measurements in identifying a predisposition to acetabular overcoverage. Methods: Hip MRI examinations performed between January 2007 and 2025 were retrospectively reviewed. Cases with bone marrow edema attributable to identifiable etiologies were excluded. Twenty-six patients with available hip or pelvis computed tomography (CT) examinations obtained within one year were included, along with an age- and sex-matched control group imaged for indications unrelated to hip pain. A total of 104 hip joints were evaluated. Alpha angles were measured on axial oblique CT reformations. Virtual pelvic radiographs generated from CT-based three-dimensional reconstructions were used for lateral center-edge angle (LCEA) measurements, and acetabular coverage was quantified using the acetabular coverage index derived from CT-MIP images. Appropriate statistical analyses were performed, with p < 0.05 considered statistically significant. Results: FAI was identified in 82.7% of cases with bone marrow edema of unknown etiology on MRI (p < 0.001), with pincer-type morphology being the most prevalent subtype (55.8%). Bone marrow edema was significantly more common in pincer-type FAI compared with other subtypes (p < 0.001) and predominantly involved the posterolateral femoral head. Mean alpha angle, LCEA, and acetabular coverage index values were significantly higher in the case group than in controls (p < 0.001). For the detection of pincer-type FAI, CT-MIP-based acetabular coverage index demonstrated superior diagnostic performance compared with LCEA (AUC, 0.917 vs. 0.855; p = 0.017), with an optimal cutoff value of 0.93 yielding high specificity and accuracy. All measurements showed excellent intraobserver and interobserver reliability. Conclusions: Femoral head bone marrow edema of unknown etiology may serve as a radiologic clue to underlying pincer-type FAI, while CT-MIP-based analyses may provide incremental value beyond conventional angular measurements in characterizing acetabular overcoverage.

Background/Objectives: Arteriovenous malformations (AVMs) in the dominant temporo-parieto-occipital (TPO) junction of the brain are extremely rare and very difficult to remove surgically because this area includes multiple sensory and language networks. Due to the fact that many patients present with bleeding, surgeons have to find a delicate balance between removing all of the AVM tissue and preserving the functional areas of the brain where important functions occur. This study is reporting a case demonstrating how precise clinical–radiologic correlation, detailed anatomical knowledge, and deliberate microsurgical techniques can allow safe removal of the AVM and improve the patient’s neurologic function without the need for additional intraoperative technology. Case Presentation: A 47-year-old right-handed male patient experienced persistent neurological deficits after experiencing a hemorrhage from an AVM in his dominant posterior hemisphere, which included mild language difficulties, right hemifacial–brachial spasticity, parietal sensory loss and a visual field defect of his right eye known as an inferior quadrantanopia localized to the TPO junction. Cerebral angiography identified a small, compact, high-flow AVM (40 × 30 mm) fed by distal branches of the middle cerebral artery (M4), posterior cerebral artery (P4), anterior cerebral artery (A4), as well as a small branch of the superior cerebellar artery (SCA). Blood drained into two veins of the Trolard and Labbé. The authors removed the AVM completely by circumferential dissection of the nidus along gliotic planes using a microscope. Feeders were then sequentially disconnected, and the venous outflow was preserved until the AVM could be removed en bloc. Post-operative angiograms demonstrated complete removal of the AVM with normalization of blood flow to the surrounding cortex. The patient’s neurologic function improved over time and at three months post-operatively, he was functioning independently (modified Rankin Scale = 1; Barthel Index = 100) and there was no evidence of residual nidus or edema on imaging. Conclusions: High-flow AVMs in the dominant TPO junction can be completely removed using a disciplined microsurgical approach and a feeder first/vein last disconnection method based on anatomy. The patient’s improvement in function represented reperfusion and reintegration of an injured but still functional network of the brain, reinforcing the idea that careful observation, a deep understanding of brain anatomy, and restrained surgical technique are critical to achieving long-term results in AVM surgery.

Natural deep eutectic solvents (NADES) have been extensively used for the extraction of a wide spectrum of plant materials. However, limited data about the in vivo toxicity of NADES extracts restrict their future practical application. In this study, we are aiming to assess the safety of a Sorbitol–lactic acid (3:1 mol./mol.; 30% water) NADES extract of Glycyrrhiza roots (GR) in mice. LC-MS/MS analysis revealed the presence of 17 metabolites, including phenolic acids, flavonoids, their glycosides, chalcones, terpene saponins, and coumarins. Interestingly, most of the identified compounds were found in higher amounts in NADES extract compared to water and EtOH extracts. No skin edema, inflammation, or erythema was observed in mice after topical application of NADES extract of GR and NADES at the doses of 50, 100, and 150 µL/mice in comparison with the control group. The calculated primary irritation index was about 0.45 both for NADES and NADES extract of GR only in high doses and falls into mild irritant categories. The individual Draize scores indicate that erythema was evident in the first three days and that all signs had disappeared by day five. No acute toxic signs or mortality of animals was observed in mice following oral administration of single doses of 4, 6, and 20 g/kg of NADES or NADES extract of GR. The NADES and extract seem to be safe at doses of up to 20 g/kg, and the LD50 was considered to be >20 g/kg. Our results open prospects for the use of NADES extract of GR for the development of transdermal and peroral formulations in the cosmetic, food, and pharmaceutical industries. Full article

Background: Bromelain, a proteolytic enzyme extracted from Ananas comosus, exhibits anti-edematous and anti-inflammatory properties that may facilitate postoperative recovery. Troxerutin and escin, respectively, a vasoactive flavonoid and a saponin derivative, also provide anti-edematous and microcirculatory benefits that could enhance tissue repair and functional outcomes. Evidence on their combined use in older adults undergoing rehabilitation after major orthopedic surgery remains limited. Methods: We conducted retrospective observational study in adults aged 65 years or older admitted to a post-acute rehabilitation unit after total hip or total knee arthroplasty. Half of the participants received an oral supplement containing bromelain (400 mg/day), troxerutin (300 mg/day), and escin (40 mg/day) for up to 21 days alongside usual care and standard medications. The primary outcome was pain reduction assessed through the Visual Analog Scale (VAS). Secondary outcomes included changes in postoperative edema and functional recovery, evaluated through range of motion, the Barthel Index, and gait performance. Result: Forty participants were enrolled (mean age 69.4 ± 7.2 years; 58 percent women). Individuals receiving the combined supplement achieved significantly greater pain improvement than controls. At day 10 (T1), VAS scores declined from 6.8 ± 1.0 to 3.2 ± 0.9 in the supplemented group versus 6.7 ± 1.1 to 4.5 ± 1.0 in controls (p < 0.01). At day 21 (T2), VAS further decreased to 1.8 ± 0.7 in the supplemented group and to 3.1 ± 0.8 with standard treatment (p < 0.001). Functional performance also improved more markedly with supplementation, with earlier mobilization and faster recovery of autonomy. No significant side effects were reported. Conclusions: In this pilot study, combined bromelain, troxerutin, and escin supplementation was associated with meaningful reductions in postoperative pain and edema and with faster functional recovery. Larger controlled trials are warranted to confirm these effects and elucidate underlying mechanisms. Full article

Diabetic macular edema (DME) is a leading cause of vision loss in patients with diabetes. While VEGF-driven vascular permeability is central to its pathogenesis, inflammation plays a complementary and pivotal role in disease progression, morphological heterogeneity, and treatment response. Readily available blood cell-derived inflammatory indices, such as the neutrophil-to-lymphocyte ratio (NLR), platelet-to-lymphocyte ratio (PLR), systemic immune-inflammation index (SII), monocyte-to-high-density lipoprotein cholesterol ratio (MHR), monocyte-to-lymphocyte ratio (MLR), platelet-to-neutrophil ratio (PNR), and pan-immune-inflammation value (PIV), as well as platelet measures (MPV, PDW), have been investigated as low-cost markers of systemic inflammation in DME. Specifically, comparative studies have reported that an NLR ≥ 2.26 can effectively distinguish DME from non-DME with 85% sensitivity and 74% specificity. Elevated NLR is more associated with serous retinal detachment. Moreover, a baseline NLR ≤ 2.32 has been linked to a better anatomical response to treatment. This narrative review summarizes the evidence regarding these biomarkers’ diagnostic and prognostic utility and highlights their associations with OCT morphotypes and anti-VEGF responsiveness. We propose that multi-marker panels integrated with OCT features may enhance risk stratification and help personalize therapy, but emphasize that prospective, multi-center validation and harmonized thresholds are required before routine clinical application.
