RESUMO

BACKGROUND: Rebound hyperglycemia following the resolution of diabetic ketoacidosis (DKA) is common in pediatric patients with type 1 diabetes, increasing the risk of recurrent DKA and complicating the transition to subcutaneous insulin. Multiple studies suggest that early administration of long-acting insulin analogs during DKA management safely improves this transition. OBJECTIVE: This study aimed to determine whether early insulin glargine administration in children with DKA prevents rebound hyperglycemia and recurrent ketosis without increasing the rate of hypoglycemia or hypokalemia. METHODS: Patients aged <21 years presenting with DKA to Children's Mercy Kansas City between October 2012 and October 2016 were reviewed. They were categorized as Early (>4 h of overlap with intravenous [IV] insulin) and Late (<2 h of overlap) cohorts. RESULTS: We reviewed 546 DKA admissions (365 Early and 181 Late). Rebound hyperglycemia (>180 mg/dL) was lower in the Early group (66% vs. 85%, p ≤ 0.0001). Hypoglycemia (<70 mg/dL) during IV insulin administration was higher in the Early group than in the Late group (27% vs. 19%, p = 0.042). Hypoglycemia within 12 h of IV insulin discontinuation was lower in the Early group (16% vs. 26%, p = 0.012). Recurrent ketosis, hypokalemia, and cerebral edema were not different between the groups. CONCLUSIONS: Early glargine administration in pediatric DKA management is safe, decreases the rate of rebound hyperglycemia, and improves the transition to subcutaneous insulin. Hypoglycemia is less frequent following IV insulin discontinuation with early glargine, but the IV insulin rate may need to be reduced to minimize hypoglycemia during IV insulin infusion.

RESUMO

BACKGROUND: Drug-coated balloon (DCB) angioplasty and drug-eluting stents (DES) are two widely used treatments for in-stent restenosis (ISR). Focal and non-focal types of ISR affect the clinical outcomes. The present study aims to compare DES reimplantation versus DCB angioplasty in acute coronary syndrome (ACS) patients with focal ISR and non-focal ISR lesions. METHODS: Patients with ISR lesions underwent percutaneous coronary intervention (PCI) were retrospectively evaluated and divided into DES group and DCB group. The primary endpoint was the incidence of target lesion failure (TLF) at 24 months follow up. Propensity score matching (PSM) was conducted to balance the baseline characteristics. RESULTS: For focal ISR, TLF was comparable in the DES and DCB groups at 24 months of follow-up (Before PSM, hazard ratio [HR]: 0.70; 95% confidence interval [CI]: 0.39-1.27; p = 0.244; After PSM, HR: 0.83; 95% CI: 0.40-1.73; p = 0.625). For non-focal ISR, TLF was significantly decreased in DES compared with DCB group (Before PSM, HR: 0.43; 95% CI: 0.29-0.63; p < 0.001; After PSM, HR: 0.33; 95% CI: 0.19-0.59; p < 0.001), which was mainly attributed to the lower incidence of clinically indicated target lesion revascularization (CD-TLR) (Before PSM, HR: 0.39; 95% CI: 0.26-0.59; p < 0.001; After PSM, HR: 0.28; 95% CI: 0.15-0.54; p < 0.001). CONCLUSIONS: The clinical outcomes for DES and DCB treatment are similar in focal type of ISR lesions. For non-focal ISR, the treatment of DES showed a significant decrease in TLF which was mainly attributed to a lower incidence of CD-TLR.

RESUMO

Background: Anterior labrum periosteal sleeve avulsion (ALPSA) lesion of the shoulder is defined as a labral avulsion with an intact periosteum of the glenoid neck resulting in medial malattachment of the labrum, which is both nonanatomic and nonfunctional. It is relatively rare compared with Bankart lesions, and its results are usually reported in combination with other anterior labroligamentous lesions in the literature. Purpose: To (1) assess the size and scope of the literature on ALPSA lesions, (2) highlight the importance of this lesion, and (3) distinguish between ALPSA and Bankart lesions in diagnostic and treatment strategies. Study Design: Scoping review; Level of evidence, 4. Methods: The PubMed, Scopus, Embase, and Google Scholar databases were searched with the keywords "ALPSA,""anterior labrum periosteal sleeve avulsion,""anterior labral periosteal sleeve avulsion," and "anterior labroligamentous periosteal sleeve avulsion" lesion. Duplicate articles and those that did not meet the inclusion criteria were excluded, resulting in the identification of 42 relevant articles. Their references were analyzed for further data curation. Results: This scoping review demonstrated that ALPSA lesions are difficult to clinically identify. Magnetic resonance angiography in the adduction internal rotation position is the most sensitive and specific imaging modality for identification. Optimal views are the anterosuperior portal for accurate identification and the anteroinferior portal for surgical repair during arthroscopy. Treatment begins with correctly identifying the labrum, in contradistinction to dense reactive fibrous tissue, and reattaching the labrum to the correct anatomic glenoid footprint. Chronic lesions with bone loss require either bone block or soft tissue augmentation procedures. Conclusion: There is paucity of exclusive literature on ALPSA lesions. It is important to distinguish this lesion from the Bankart lesion as it is associated with worse outcomes. The higher failure rates of ALPSA lesion repair indicate that the current repair techniques require further refinement to improve the outcomes to the standard of Bankart lesions.

RESUMO

The term "recurrent constellations of embryonic malformations" (RCEM) is used to describe a number of multiple malformation associations that affect three or more body structures. The causes of these disorders are currently unknown, and no diagnostic marker has been identified. Consequently, providing a definitive diagnosis in suspected individuals is challenging. In this study, genome-wide DNA methylation analysis was conducted on DNA samples obtained from the peripheral blood of 53 individuals with RCEM characterized by clinical features recognized as VACTERL and/or oculoauriculovertebral spectrum association. We identified a common DNA methylation episignature in 40 out of the 53 individuals. Subsequently, a sensitive and specific binary classifier was developed based on the DNA methylation episignature. This classifier can facilitate the use of RCEM episignature as a diagnostic biomarker in a clinical setting. The study also investigated the functional correlation of RCEM DNA methylation relative to other genetic disorders with known episignatures, highlighting the common genomic regulatory pathways involved in the pathophysiology of RCEM.

RESUMO

Pollution control and environmental protection of the Yangtze River have received major attention in China. However, modeling the river's pollution load remains challenging due to limited monitoring and unclear spatiotemporal distribution of pollution sources. Specifically, anthropogenic activities' contribution to the pollution have been underestimated in previous research. Here, we coupled a hydrodynamic-based water quality (HWQ) model with a machine learning (ML) model, namely attention-based Gated Recurrent Unit, to decipher the daily pollution loads (i.e., chemical oxygen demand, COD; total phosphorus, TP) and their sources in the Middle-Lower Yangtze River from 2014 to 2018. The coupled HWQ-ML model outperformed the standalone ML model with KGE values ranging 0.77-0.91 for COD and 0.47-0.64 for TP, while also reducing parameter uncertainty. When examining the relative contributions at the Middle Yangtze River Hankou cross-section, we observed that the main stream and tributaries, lateral anthropogenic discharges, and parameter uncertainty contributed 15, 66, and 19% to COD, and 58, 35, and 7% to TP, respectively. For the Lower Yangtze River Datong cross-section, the contributions were 6, 69, and 25% for COD and 41, 42, and 17% for TP. According to the attention weights of the coupled model, the primary drivers of lateral anthropogenic pollution sources, in descending order of importance, were temperature, date, and precipitation, reflecting seasonal pollution discharge, industrial effluent, and first flush effect and combined sewer overflows, respectively. This study emphasizes the synergy between physical modeling and machine learning, offering new insights into pollution load dynamics in the Yangtze River.

RESUMO

Our study probed the differences in ion channel gene expression in the endometrium of women with Recurrent Implantation Failure (RIF) compared to fertile women. We analyzed the relative expression of genes coding for T-type Ca2+, ENaC, CFTR, and KCNQ1 channels in endometrial samples from 20 RIF-affected and 10 control women, aged 22-35, via microarray analysis and quantitative real-time PCR. Additionally, we examined DNA methylation in the regulatory region of KCNQ1 using ChIP real-time PCR. The bioinformatics component of our research included Gene Ontology analysis, protein-protein interaction networks, and signaling pathway mapping to identify key biological processes and pathways implicated in RIF. This led to the discovery of significant alterations in the expression of ion channel genes in RIF women's endometrium, most notably an overexpression of CFTR and reduced expression of SCNN1A, SCNN1B, SCNN1G, CACNA1H, and KCNQ1. A higher DNA methylation level of KCNQ1's regulatory region was also observed in RIF patients. Gene-set enrichment analysis highlighted a significant presence of genes involved with ion transport and membrane potential regulation, particularly in sodium and calcium channel complexes, which are vital for cation movement across cell membranes. Genes were also enriched in broader ion channel and transmembrane transporter complexes, underscoring their potential extensive role in cellular ion homeostasis and signaling. These findings suggest a potential involvement of ion channels in the pathology of implantation failure, offering new insights into the mechanisms behind RIF and possible therapeutic targets.

RESUMO

Background: Several studies have examined return to play (RTP) and outcomes following the Latarjet procedure in contact athletes. Purpose: To investigate clinical outcomes affecting RTP following the Latarjet procedure in contact athletes. Study Design: Case series; Level of evidence, 4. Methods: A total of 67 contact athletes (72 shoulders) ≤35 years old who underwent Latarjet procedure for recurrent shoulder instability between January 1, 2018, and March 31, 2022, were retrospectively identified. Demographic information, medical history, surgical history, number of dislocations before surgery, and postoperative complications up to 6 months after surgery were reviewed. Outcomes evaluated included RTP, competition level, satisfaction, and patient-reported outcomes including visual analog scale for pain, American Shoulder and Elbow Surgeons (ASES) Score, and Disabilities of the Arm, Shoulder and Hand (DASH) scores. Results: There were a total of 67 patients (72 shoulders) included in the study with a mean age at surgery of 19.7 years for all shoulders. Of the total cohort, 46 patients (50 shoulders; [69.4%]) were available for follow-up by phone. Of the 46 patients contacted by phone, 22/46 were football players; 30/50 [60.0% of all shoulders]) were contact athletes and 19/46 [41.3%] limited contact athletes) were interviewed with a mean follow-up of 25.5 months (range, 10-49 months). Of 72 patients, 22 (30.6% of shoulders and 32.8% of patients) patients had prior shoulder surgery, most commonly arthroscopic stabilization. Only 1 patient experienced hardware failure, but this did not require reoperation. Sixteen of 46 (35%) athletes competed at the collegiate level, and 24/46 (52%) were high school athletes at the time of surgery; 34 of 46 patients (74%) returned to play, of which 30 of the 34 (88%) returned to playing at the same competition level; 15 of 22 (68%) football players returned to play. Only 4 of 51 (8%) reported subjective recurrent instability. Postoperative mean ASES score was 92.2, DASH score was 5.6, and visual analog scale for pain score was 4 (range, 0-50). A total of 43 of 46 (93%) patients reported improvement in quality of life after undergoing the Latarjet procedure for shoulder instability. Eight of 72 (11.1%) shoulders had unresolved pain or stiffness 6 months postoperatively, and 2 of 72 (2.8%) required revisions. Conclusion: Patient RTP, outcomes, and satisfaction were high following the Latarjet procedure in young contact athletes.

RESUMO

Recurrent pregnancy loss (RPL), often known as spontaneous miscarriages occurring two or more times in a row, is a reproductive disease that affects certain couples. The cause of RPL is unknown in many cases, leading to difficulties in therapy and increased psychological suffering in couples. Toll-like receptors (TLR) have been identified as crucial regulators of inflammation in various human tissues. The occurrence of inflammation during parturition indicates that Toll-like receptor activity in tissues related to pregnancy may play a crucial role in the onset and continuation of normal function, as well as in various pregnancy complications like infection-related preterm. TLRs or their signaling molecules may serve as effective therapeutic targets for inhibiting premature activity. At the maternal-fetal interface, TLRs are found in both immune and non-immune cells, such as trophoblasts and decidual cells. TLR expression patterns are influenced by the phases of pregnancy. In this way, translational combinations like epigenetics, have indicated their impact on the TLRs.Importantly, abnormal DNA methylation patterns and histone alterations have an impressive performance in decreasing fertility by influencing gene expression and required molecular and cellular activities which are vital for a normal pregnancy and embryonic process. TLRs, play a central duty in the innate immune system and can regulate epigenetic elements by many different signaling pathways. The potential roles of TLRs in cells, epigenetics factors their ability to identify and react to infections, and their place in the innate immune system will all be covered in this narrative review essay.

RESUMO

Animal behavior emerges from collective dynamics of neurons, making it vulnerable to damage. Paradoxically, many organisms exhibit a remarkable ability to maintain significant behavior even after large-scale neural injury. Molecular underpinnings of this extreme robustness remain largely unknown. Here, we develop a quantitative pipeline to measure long-lasting latent states in planarian flatworm behaviors during whole-brain regeneration. By combining >20,000 animal trials with neural network modeling, we show that long-range volumetric peptidergic signals allow the planarian to rapidly restore coarse behavior output after large perturbations to the nervous system, while slow restoration of small-molecule neuromodulator functions refines precision. This relies on the different time and length scales of neuropeptide and small-molecule transmission to generate incoherent patterns of neural activity that competitively regulate behavior. Controlling behavior through opposing communication mechanisms creates a more robust system than either alone and may serve as a generalizable approach for constructing robust neural networks.

RESUMO

We present a female in her sixties with a recurrent paraesophageal hernia status post open Nissen fundoplication and multiple esophageal dilations who underwent a robotic paraesophageal hernia repair, with extensive lysis of adhesions. The stomach and esophagus were dissected off the crura and the previous wrap was undone. Once the entirety of the stomach and esophagus were freed from their surrounding structures, the hernia sac was able to be excised. The crural defect was closed and gastropexy was performed. The patient had an uneventful postoperative course and was discharged home. This case is presented to provide evidence that robotic repair presents a viable option in the reoperation of patients following an open Nissen fundoplication as well as provide an overview of the types of hiatal hernias and the indications and options for surgical intervention.

RESUMO

Ovarian cancer is a leading cause of death from gynecological cancers worldwide. Platinum-based chemotherapy provides the cornerstone of the medical management. In first line and subsequent relapses, maintenance strategies are offered to prolong intervals between lines of chemotherapy. Current maintenance options involve bevacizumab and poly ADP-ribose polymerase inhibitors, but these lines of therapy can only be used once in the disease course. Patients in first or second platinum sensitive relapse after poly ADP-ribose polymerase inhibitors and bevacizumab represent an area of unmet medical need. This academic sponsored, international Phase II randomized trial is evaluating the combination of a therapeutic cancer vaccine (OSE2101) with anti-PD1 (pembrolizumab) as maintenance therapy, in patients with platinum-sensitive recurrence regardless of number of prior lines and no progression after platinum-based chemotherapy.Clinical Trial Registration: NCT04713514 (ClinicalTrials.gov).


Ongoing Phase II study randomizing vaccine OSE2101 +/- Pembrolizumab vs supportive care as maintenance in platinum-sensitive recurrent ovarian cancer.

RESUMO

Background: Ovarian cancer (OC) is a gynecological malignancy with a high mortality rate worldwide. The unfavorable prognosis of OC is mainly attributed to the recurrent propensity. Recently, mortality from OC has exhibited a downward trend. These favorable patterns are likely to be driven by advancements in novel therapeutic regimens. However, there is a lack of visualize analysis of the application of these new drugs on women with recurrent OC (ROC). Therefore, we aimed to provide a bibliometric analysis of the evolving paradigms in the ROC treatment. Methods: Documents on ROC treatment were systematically collected from the MEDLINE database and Web of Science Core Collection (WOSCC). The retrieved documents were exported in the plain text file format, and files were named and saved to the paths specified by the Java application. Microsoft Excel (version 2010), Citespace (6.2.R4) and VOSviewer (1.6.19) were used for data analysis, and included the following: 1) annual publication trend; 2) contributions of countries, institutions and authors; 3) co-citation of journals and references; and 4) co-occurrence of keywords. Results: A total of 914 documents published in the MEDLINE and 9,980 ones in WOSCC were retrieved. There has been an upward trend in the productivity of publications on ROC treatment on by years. The United States was the leading contributor in this field, and the University of Texas System stood out as the most productive institution. Giovanni Scambia and Maurie Markman were the research leaders in the field of ROC treatment. The journal Gynecologic Oncology had the highest citation frequency. The reference entitled with "Niraparib Maintenance Therapy in Platinum-Sensitive, Recurrent Ovarian Cancer" got highest centrality of 0.14 in the co-citation network. Keyword analysis revealed that the focus of current ROC treatment was on platinum-based anticancer drugs, paclitaxel, angiogenesis inhibitors (AIs), immune checkpoint inhibitors (ICIs) and poly (ADP-ribose) polymerase inhibitors (PARPis). Conclusion: Scholars from a multitude of countries have been instrumental in the advancement of ROC treatment. The research hotspots and trend in the field of predominantly originated from leading international journals and specialized periodicals focused on gynecologic oncology. Maintenance therapy using AIs or (and) PARPis has emerged as a significant complement to platinum-based chemotherapy for patients with ROC.

RESUMO

OBJECTIVE: This study aims to analyze the safety and effectiveness of a new model of surgery combined with Photodynamic therapy for treating Recurrent Respiratory Papillomatosis (RRP). METHODS: Review the case data of patients with RRP who opted for comprehensive surgery combined with Photodynamic therapy at the Nanjing BenQ Medical Center, from January 2021 to May 2023. The efficacy of this program was evaluated by comparing the annual number of surgeries and Derkay scores before and after the surgery. RESULTS: A total of 23 RRP patients were included in the study. After treatment, the recurrence rate was 65.2 % (15/23), with an average recurrence time of 94.3 ± 50.8 days. The average Derkay score at the time of recurrence was significantly lower than the average pre-treatment Derkay score (P < 0.001). The average annual recurrence rate before treatment was 2.2 ± 1.3, compared to 1.5 ± 1.5 after treatment, with no significant difference (P = 0.16). However, subgroup analysis revealed a significant decrease in the annual recurrence rate of adult-onset RRP after treatment (P = 0.01). The most common adverse reaction was mild pharyngeal pain (11/23). There were 3 cases of new-onset vocal cord adhesions. No patients experienced serious respiratory-related adverse reactions, anesthesia-related adverse reactions, or systemic phototoxic reactions. CONCLUSION: In conclusion, this study indicates that surgery combined with Photodynamic therapy (PDT) might be a safe and effective option for treating RRP, especially in patients with Adult-Onset Recurrent Respiratory Papillomatosis (AORRP).

RESUMO

INTRODUCTION: Vagal nerve stimulator (VNS) implantation is a vital therapy for epilepsy refractory to other treatments; however, it is associated with a very high rate of voice changes. Relatively few of these patients are evaluated for vocal fold motion impairments. In this series, we evaluate 5 such patients with a novel phenotype of forced abduction with VNS stimulation. METHODS: Retrospective case series. RESULTS: Five patients with a VNS implant who underwent operative direct or in-office rigid laryngoscopy and had vocal fold motion impairment associated with VNS activation are included. All 5 patients had vocal fold mobility with VNS off and a fixed with activation. All patients exhibited vocal fold abduction with VNS activation. Patient 2 has since undergone laryngeal reinnervation, which helped her intermittent dysphonia but left a small glottic gap. A type 1 thyroplasty corrected this gap and improved her voice further. Patient 3 has undergone laryngeal reinnervation for which early results show improvement in perceptual and patient reported outcomes. Patients 4 and 5 have both undergone laryngeal reinnervation with improvement in voice. CONCLUSION: Previous reported cases of stimulated immobility associated with VNS use describe only adduction of the vocal fold. This series expands the previous work showing the VNS activation can also cause stimulated immobility in an abducted position, for which reinnervation and other medialization procedures offer promising treatment.

RESUMO

BACKGROUND: Patients with pilonidal disease (PD) can present with concurrent draining secondary sinus at the superior gluteal cleft. The natural disease course in the setting of this severe phenotype is poorly characterized. We present the largest cohort of patients with PD and concurrent secondary sinus. METHODS: Patients with PD and concurrent secondary sinus who underwent Gips procedure with secondary sinus excision from 2019 to 2023 were prospectively followed. Patient demographics, drainage recurrence, symptom resolution, treatment, and follow-up period were recorded. Recurrent drainage from previous secondary sinus site was defined as isolated painless serous drainage after the wound had closed for > 3 weeks; recurrent PD was characterized as recurrent pain and bloody drainage after excision. RESULTS: One hundred and five patients (seventy-one males) with a median age of 17.2 years [interquartile range (IQR):15.4-19.0] underwent excision of their disease and were followed for a median of 367.0 days (IQR: 173.2-658.8). Without regular epilation, six patients (5.7%, five males, one female) had recurrent PD. With regular epilation, three patients (2.8%, three males) had recurrent PD. Eight patients (7.5%, six males, two females) had recurrent secondary sinus site drainage. Median time to recurrent drainage was 75.5 days (IQR: 65.2-216.2) after excision and for recurrent drainage to resolve was 72 days (IQR: 49-81). Recurrent secondary sinus site drainage was treated with antibiotics, silver nitrate, debridement, or no treatment. CONCLUSION: Patients who present with PD in the setting of concurrent secondary sinus have a unique, more severe disease phenotype. Excision can be complicated by recurrent drainage from the secondary sinus site that can resolve without repeat surgical excision.

RESUMO

Classification of protein families from their sequences is an enduring task in Proteomics and related studies. Numerous deep-learning models have been moulded to tackle this challenge, but due to the black-box character, they still fall short in reliability. Here, we present a novel explainability pipeline that explains the pivotal decisions of the deep learning model on the classification of the Eukaryotic kinome. Based on a comparative and experimental analysis of the most cutting-edge deep learning algorithms, the best deep learning model CNN-BLSTM was chosen to classify the eight eukaryotic kinase sequences to their corresponding families. As a substitution for the conventional class activation map-based interpretation of CNN-based models in the domain, we have cascaded the GRAD CAM and Integrated Gradient (IG) explainability modus operandi for improved and responsible results. To ensure the trustworthiness of the classifier, we have masked the kinase domain traces, identified from the explainability pipeline and observed a class-specific drop in F1-score from 0.96 to 0.76. In compliance with the Explainable AI paradigm, our results are promising and contribute to enhancing the trustworthiness of deep learning models for biological sequence-associated studies.

RESUMO

BACKGROUND: Radical surgery remains the primary option for locally recurrent rectal cancer (LRRC) as it has the potential to considerably extend the patient's lifespan. At present, the effectiveness of laparoscopic surgery for LRRC remains unclear. METHODS: The clinical data of patients with LRRC who were admitted to the Cancer Hospital of the Chinese Academy of Medical Sciences between 2015 and 2021 were retrospectively analyzed in this study. Patients were categorized into two groups, namely the open group and the laparoscopic group, based on the surgical method used. Propensity score matching was used to reduce baseline differences. The short-term outcomes and long-term survival between the two groups were compared. RESULTS: Curative surgery was performed on 111 patients who were diagnosed with LRRC. After propensity score matching, a total of 80 patients were included and divided into the laparoscopic group (40 patients) and the open group (40 patients). The laparoscopic group had less intraoperative bleeding (100 vs. 300, P = 0.011), a lower postoperative complication rate (20.0% vs. 42.5%, P = 0.030), a lower incidence of wound infection (0 vs. 15.0%, P = 0.026), and a shorter time to first flatus (2 vs. 3, P = 0.005). The laparoscopic group had higher 3-year overall survival (85.4% vs. 57.5%, P = 0.016) and 3-year disease-free survival (63.9% vs 36.5%, P = 0.029). CONCLUSIONS: In comparison to open surgery, laparoscopic surgery is linked to less bleeding during the operation, quicker recovery after the surgery, and a lower incidence of infections at the surgical site. Moreover, laparoscopic surgery for LRRC might yield superior long-term survival outcomes.

RESUMO

OBJECTIVE: The ratio of myeloperoxidase to high-density lipoprotein (MPO/HDL) has become a novel inflammatory biomarker in the field of cardiovascular disease. MPO and HDL have been reported to be associated with inflammation and lipid metabolism after AIS. However, the effect of MPO/HDL on AIS recurrence has not been studied. We aimed to assess the value of MPO/HDL in predicting relapse 90 days after AIS. METHODS: A total of 363 patients diagnosed with AIS were followed up for 90 days. Patients were assessed for recurrence within 90 days after AIS. Univariate and multivariate analyses were performed to determine the association between MPO/HDL and relapse within 90 days in AIS patients. The receiver operating characteristic curve (ROC) was used to compare the predictive value of MPO, HDL and MPO/HDL for recurrence at 90 days after AIS. RESULTS: The proportion of recurrent stroke patients within 90 days was 6.61% (24/363). Recurrent stroke was associated with NIHSS, WBC, NEUT, UA, DD, Hcy, MPO, HDL, and MPO/HDL. After adjusting for potential confounders, the 90-day recurrence risk of AIS patients increased by 0.03 (P < 0.001) for each unit increase in MPO/HDL. The ROC curve constructed after correcting confounders found that compared with MPO(AUC=0.9698) and HDL(AUC=0.821), MPO/HDL showed the highest AUC value (AUC=0.9801), indicating that MPO/HDL levels had the highest predictive value for 90-day relapse in AIS patients. CONCLUSIONS: MPO and MPO/HDL were independently associated with relapse within 90 days of AIS. MPO/HDL may be an independent predictor of 90-day relapse in AIS patients.
