Background: Recent clinical trials have shown that patients with large ischemic cores have better outcomes with endovascular thrombectomy (EVT) compared with standard medical treatment (SMT) alone.We aim to assess whether the relationship between EVT and improvements in clinical outcomes varies depending on the location of the occlusive sites.
Methods: This study is a subgroup analysis conducted within a prospective, nationwide, multi-center registry. The cohort included patients with acute large vessel occlusion in the anterior circulation and an Alberta Stroke Program Early Computed Tomography Score of 0 to 5 within 24 hours from last known well. We utilized the adjusted common odds ratio for a shift toward better outcome on the modified Rankin Scale after EVT compared with SMT alone as the primary outcome. Safety outcomes included symptomatic intracranial hemorrhage (sICH).
Results: A total of 745 patients with large ischemic cores were included: 272(36.5%) with internal carotid artery occlusion, 392(52.6%) with M1 segment of the middle cerebral artery occlusion, and 81(11.0%) with M2 segment of the middle cerebral artery occlusion. The adjusted common odds ratios were as follows: 1.98 (95% CI, 1.01-3.89) for ICA occlusions, 2.09 (95% CI, 1.35-3.23) for M1 occlusions, and 1.13 (95% CI, 0.43-2.94) for M2 occlusions. There was no significant treatment-by-occlusion site interaction observed (P=0.69). However, the incidence of sICH was significantly greater in all groups receiving EVT than in those receiving SMT alone. Additionally, we observed that the secondary outcomes and subgroup analyses were generally consistent with the main outcomes.
Conclusions: In this study, we found that patients with internal carotid artery and M1 occlusion demonstrated a better outcome with EVT, while the benefit for patients with M2 occlusion remains uncertain.

Background: Joint contractures and nerve injuries are common after hand burns. Extracorporeal shock wave therapy (ESWT) is effective not only for the regeneration of various tissues, including scar tissues, but also for reducing pain and pruritus in patients with burns. Researchers have attempted to explore the effects of ESWT on hand dysfunction caused by nerve injury following burns.
Materials and methods: We evaluated the effects of ESWT (compared to sham stimulation) on hands with nerve injury and hypertrophic scars and thereby on hand function. The current study was a double-blind randomized controlled trial involving 120 patients. The ESWT parameters were as follows: energy flux density, 0.05-0.30 mJ/mm2; frequency, 4 Hz; 1000 to 3000 impulses per treatment; and 12 treatments, one/week for 12 weeks. Outcome measures were as follows: 10-point visual analog scale for pain, Jebsen-Taylor hand function test, grip strength, Purdue Pegboard test, ultrasound measurement of scar thickness, and skin characteristics before and immediately after 12 weeks of treatment.
Results: No significant inter-group difference was noted after the initial evaluation (P>0.05). More significant improvements were found in the ESWT group than in the sham group in terms of the VAS score (P=0.004), extension ROMs of hand joints (P=0.02), the JTT scores (writing, small, and light) (P<0.001, P<0.001, and P=0.002), and skin characteristics (melanin, skin distensibility, and biologic skin elasticity) (P=0.004, P<0.001, and P<0.001). Other measured outcomes did not differ between the two groups after the treatment.
Conclusion: We identified the clinically beneficial effects of ESWT in promoting hand function, improving scarring, and alleviating scarring-related pain, thereby highlighting its advantages in improving hand function that has been impaired due to nerve injury and hypertrophic scars after burns.

Background: Early diagnosis remains an obstacle for improving the outcome of lung adenocarcinoma (LUAD). DNA methylation changes in peripheral blood mononuclear cells (PBMCs) could reflect immune response to tumorigenesis, providing the theoretical basis for early cancer diagnosis based on immune cell profiling.
Methods: This multi-center study evaluated the DNA methylation patterns based on PBMCs samples from 1115 individuals at nine medical centers. Genome-wide DNA methylation profiling of PBMCs in a discovery cohort (35 LUAD patients and 50 healthy controls) was performed using Illumina 850K microarray. Candidate differentially methylated CpG positions (DMPs) were selected and validated in a two-step DMPs screening cohort (65 LUAD patients and 80 healthy controls) by pyrosequencing and multiple target region methylation enrichment sequencing (MTRMES). Then, an early LUAD Diagnostic Panel (LDP score) based on multi-site methylation-specific chip-based digital PCR was constructed in a training set and then confirmed in a validation set from the LDP score development cohort (389 AIS/stage I LUAD patients and 293 healthy controls). Besides, we included 157 other cancer patients, including 52 gastric cancer (GC) patients, 50 breast cancer (BC) patients, and 55 colorectal cancer (CRC) patients to assess the specificity of LDP score. In addition, we also evaluated the early warning ability of LDP score for LUAD in a prospective cohort (46 people who were at high-risk of developing LC).
Results: A total of 1415 LUAD-specific DMPs were identified. Then, six DMPs were selected for validation and three DMPs were finally verified. The LDP score was constructed by combining the three DMPs, age, and gender, and showed an AUC of 0.916, sensitivity of 88.17%, and specificity of 80.20% in combined set, outperforming traditional methods, such as CEA and CT (detection rate: 87.79% vs. 4.69%; 87.79% vs. 35.21%). This diagnostic performance was confirmed in sub-types of LUAD with clinical challenges, such as 6-20 mm LUAD (AUC: 0.914, 95%CI: 0.889-0.934) and ground-glass nodules (AUC: 0.916, 95%CI: 0.889-0.938). Importantly, our LDP score had significant improvement in terms of selecting high-risk individuals who should receive low-dose computed tomography (87.80% vs. 9.28%). Remarkably, LDP score could predict LUAD around two years before clinical diagnosis in our prospective cohort.
Conclusions: The novel developed LDP score represented a convenient and effective assay for the detection of AIS/stage I LUAD with high sensitivity and specificity, and had demonstrated unique advantages over traditional detection methods.

Few studies have illustrated the role of the joint line convergence angle (JLCA) in the correlation between the arithmetic hip-knee-ankle angle (aHKA) and mechanical hip-knee-ankle angle (mHKA). We aimed to determine this role and to evaluate the effect of the JLCA in predicting constitutional alignment using the aHKA. A total of 107 normal participants (214 knees) and 246 patients (477 knees) with osteoarthritis(OA) were retrospectively examined using long-leg radiographs. The formula was calculated geometrically on plain radiographs of the knee based on the relationships among the mHKA, aHKA, and JLCA, and the distribution of the JLCA between the groups was determined. The effect of the JLCA on the prediction of constitutional alignment using the aHKA were evaluated. The geometric formula was determined to be 'mHKA=180°+aHKA - JLCA', and was verified. The median (quartile 1, quartile 3) JLCA was 2.0° (1.0°, 3.5°) and 2.5° (1.0°, 4.5°) in the normal and OA groups, respectively. The JLCA affected the prediction of constitutional alignment based on the aHKA. It should be considered when constitutional alignment is predicted based on the aHKA in patients with high JLCA values.

Background: Crohn's disease is a chronic, relapsing form of inflammatory bowel disease marked by severe gastrointestinal inflammation and a broad range of debilitating symptoms. Despite advances in medical treatments, achieving sustained remission remains challenging for many patients. This umbrella review aims to consolidate evidence from various systematic reviews to evaluate the efficacy and safety of stem cell therapies in treating Crohn's disease.
Methods: This review followed the Joanna Briggs Institute methodology and adhered to PRISMA guidelines. A literature search of PubMed, Web of Science, Embase, and the Cochrane Library covered records up to April 20, 2024. Only systematic reviews and meta-analyses on stem cell therapy for Crohn's disease were considered. Data were extracted and analyzed for clinical efficacy indicators like remission induction and safety metrics, including adverse events and mortality rates.
Results: Sixteen systematic reviews were included, spanning studies conducted between 2009 and 2023. Stem cell therapy showed a pooled risk ratio (RR) of 1.299 (95% CI: 1.192 to 1.420) for clinical remission, indicating a 29.9% increased likelihood of remission compared to controls. The pooled RR for healing perianal Crohn's disease was 1.358 (95% CI: 1.13 to 1.631), suggesting a 35.8% increased likelihood of healing. A pooled RR of 1.481 (95% CI: 1.036 to 2.116) shows a 48.1% higher immediate fistula closure rate with stem cell therapy. For long-term outcomes, a RR of 1.422 (95% CI: 1.091 to 1.854) indicates a 42.2% increased likelihood of maintaining closure. However, stem cell therapy did not significantly impact Crohn's Disease Activity Index (CDAI) (RR: 1.154, 95% CI: 0.193 to 6.883) and Perianal Disease Activity Index (PDAI) scores (mean difference at 12 weeks: -0.505, 95% CI: -2.481 to 1.471; mean difference at 24 weeks: -0.338, 95% CI: -1.638 to 0.963). The safety profile was comparable to conventional therapies, with a pooled RR of 0.972 (95% CI: 0.739 to 1.278) for adverse events and 1.136 (95% CI: 0.821 to 1.572) for serious adverse events.
Conclusion: Stem cell therapy offers significant progress in treating Crohn's disease, particularly in complex cases, by improving fistula closure rates and suggesting potential as a supplementary therapy.

A literature search of PubMed, Web of Science, Embase, and the Cochrane Library covered records up to April 20, 2024.

Data were extracted and analyzed for clinical efficacy indicators like remission induction and safety metrics, including adverse events and mortality rates.</p><p><strong>Results: </strong>Sixteen systematic reviews were included, spanning studies conducted between 2009 and 2023. Stem cell therapy showed a pooled risk ratio (RR) of 1.299 (95% CI: 1.192 to 1.420) for clinical remission, indicating a 29.9% increased likelihood of remission compared to controls. The pooled RR for healing perianal Crohn's disease was 1.358 (95% CI: 1.13 to 1.631), suggesting a 35.8% increased likelihood of healing. A pooled RR of 1.481 (95% CI: 1.036 to 2.116) shows a 48.1% higher immediate fistula closure rate with stem cell therapy. For long-term outcomes, a RR of 1.422 (95% CI: 1.091 to 1.854) indicates a 42.2% increased likelihood of maintaining closure. However, stem cell therapy did not significantly impact Crohn's Disease Activity Index (CDAI) (RR: 1.154, 95% CI: 0.193 to 6.883) and Perianal Disease Activity Index (PDAI) scores (mean difference at 12 weeks: -0.505, 95% CI: -2.481 to 1.471; mean difference at 24 weeks: -0.338, 95% CI: -1.638 to 0.963). The safety profile was comparable to conventional therapies, with a pooled RR of 0.972 (95% CI: 0.739 to 1.278) for adverse events and 1.136 (95% CI: 0.821 to 1.572) for serious adverse events.</p><p><strong>Conclusion: </strong>Stem cell therapy offers significant progress in treating Crohn's disease, particularly in complex cases, by improving fistula closure rates and suggesting potential as a supplementary therapy.

Background: Despite considerable research efforts, the precise etiology and underlying pathways contributing to Moyamoya Disease (MMD) remain poorly understood. Moreover, the overlapping vascular pathologies shared between MMD and Intracranial Atherosclerotic Disease (ICAD) pose challenges in clinical differentiation, even with gold-standard cerebral angiography. An in-depth exploration of lipidomic alterations in cerebral intracranial MMD vessels could offer valuable insights into the pathogenesis of MMD-related mechanisms, encompassing MMD and ICAD, and unveil novel biomarkers and potential therapeutic targets. However, to date, comprehensive lipidomic profiling has been lacking.
Materials and methods: To discover novel biomarkers and unravel the pathophysiological mechanisms underlying MMD, we conducted a lipidomics analysis to characterize various lipid species in matched human extracranial and intracranial artery tissues from patients diagnosed with MMD (n=99) and ICAD (n=12).
Results: Our analysis identified 569 lipid species and delineated a robust panel of lipidomic biomarkers capable of effectively distinguishing MMD from ICAD (area under curve=0.98), as determined by receiver operating characteristic curve analysis. Notably, we observed a significantly more pronounced positive correlation of diacylglycerols and a negative association of triglycerides in intracranial artery tissues of MMD patients compared to those with ICAD, suggesting a potential role of dysregulated diacylglycerol-induced signaling in MMD pathogenesis. Furthermore, our investigation into the correlations of critical differential intracranial artery vessel lipid species between MMD and ICAD and clinical parameters revealed negative associations with plasma iron levels, implying a potential link between plasma iron metabolism and artery lipid homeostasis during MMD pathogenesis.
Conclusion: These findings offer promising prospects for advancing clinical diagnosis for enhanced differentiation between the two disease conditions. Additionally, they shed light on the fundamental mechanisms implicated in MMD pathogenesis and suggest potential therapeutic avenues through targeting artery vessel lipids or plasma iron levels.
