Glutaric acidemia type 1 (GA1) presents unique challenges in prenatal diagnosis, especially in cases with no family history. This review article aims to review and present the prenatal ultrasound and magnetic resonance findings of GA1 and consolidate key insights into the difficulties associated with GA1 prenatal diagnosis and the neuroimaging features that require careful differentiation during the diagnostic process.

Alternative therapy for lymphoma with febrile neutropenia using traditional Chinese medicine: A case report.

INTRODUCTION: Febrile neutropenia is a common complication in patients undergoing chemotherapy for hematologic malignancies and is associated with significant morbidity and mortality. Primary granulocyte colony-stimulating factor (G-CSF) prophylaxis is consistently associated with a notable reduction in the risk of febrile neutropenia. However, the use of G-CSF in patients who are already neutropenic from chemotherapy remains controversial. Studies have shown that 12.9 % of cancer patients incorporate traditional Chinese medicine (TCM) to alleviate chemotherapy side effects in Taiwan; thereby providing an alternative management strategy for febrile neutropenia in cancer patients. CASE PRESENTATION: This is an 18-year-old female with newly diagnosed precursor T-lymphoblastic lymphoma. After chemotherapy, the patient developed febrile neutropenia. Despite the use of antibiotics and G-CSF, the febrile neutropenia persisted for two months. Approximately ten days after the initiation of traditional Chinese medicine decoction with the strategy of tonifying the spleen and stomach, clearing yin fire, and uplifting yang, her absolute neutrophil count (ANC) had gradually increased. Additionally, after two weeks of treatment, her fever subsided. The patient continued with chemotherapy and was discharged in stable condition. DISCUSSION: Antibiotic use aligns with the TCM perspective of an "attack" approach. Conversely, our TCM decoction was designed to raise the ANC by tonifying the spleen and stomach, clearing Yin Fire, and uplifting Yang. Li Dongyuan, one of the four great masters of the Jin Yuan Dynasty, created the formula: Bupiwei Shengyang Sanhuo Decoction that is notable in this regard. The herbs in our decoction have shown hematopoietic and myelosuppression-alleviating effect. For many patients who do not respond adequately to G-CSF alone, integrative treatments involving both TCM and Western medicine can offer additional therapeutic benefits by increasing blood cell counts.

Asthma control associated with anxiety and depression in asthmatic children following post-acute COVID-19.

BACKGROUND: Poor asthma control may adversely affect mental health. Our study investigates the correlation between inadequate asthma control, exhaled nitric oxide (FENO) levels, and anxiety and depression among pediatric asthma patients with COVID-19. METHODS: This prospective case-control study enrolled 520 asthmatic children (8-15 years), including 336 patients diagnosed with COVID-19 after rapid antigen testing at home and 184 age-matched asthmatic patients without COVID-19 infection. FENO and spirometry were performed 1 month after COVID-19 infection. Scores for Child Anxiety-Related Disorders (SCARED) and depression screen derived from Patient Health Questionnaire-9 (PHQ-9) to assess their mental health status. Childhood asthma control test (C-ACT), FENO levels, and spirometry were correlated with the SCARED and PHQ-9 questionnaires. RESULTS: SCARED subscales, including generalized anxiety disorder, social anxiety disorder, school avoidance, and depression scores from PHQ-9, exhibited a significant increase in asthmatic patients diagnosed with COVID-19 (p < .05). Among asthmatic children with SARS-CoV-2 infection, the poor asthma control group exhibited the highest SCARED and PHQ-9 measurements (p < .01). Multiple linear regression analysis indicated that reduced C-ACT scores and elevated FENO levels in asthmatic children with COVID-19 were significant risk factors for both anxiety and depression scores (p < .05). Lower C-ACT scales were associated with high scores of SCARED (r = -0.471) and PHQ-9 (r = -0.329) in asthmatic children (p < .001). CONCLUSIONS: The current study emphasizes the need for healthcare professionals to closely monitor asthma control in asthmatic children to prevent heightened risks of depression and anxiety during the ongoing COVID-19 pandemic.

Implementation of First-trimester Screening and Prevention of Preeclampsia: a Stepped Wedge Cluster-randomized Trial in Asia.

BACKGROUND: This trial aimed to assess the efficacy, acceptability and safety of a first-trimester screen-and-prevent strategy for preterm preeclampsia (PE) in Asia. METHODS: Between 1st August 2019 and 28th February 2022, this multicenter stepped wedge cluster randomized trial included maternity/diagnostic units from ten regions in Asia. The trial started with a period where all recruiting centers provided routine antenatal care without study-related intervention. At regular six-week intervals, one cluster was randomized to transit from non-intervention phase to intervention phase. In the intervention phase, women underwent first-trimester screening for preterm PE using a Bayes theorem-based triple-test. High-risk women, with adjusted risk for preterm PE ≥ 1 in 100, received low-dose aspirin from <16 weeks until 36 weeks. RESULTS: Overall, 88.04% (42,897/48,725) of women agreed to undergo first-trimester screening for preterm PE. Among those identified as high-risk in the intervention phase, 82.39% (2,919/3,543) received aspirin prophylaxis. There was no significant difference in the incidence of preterm PE between the intervention and non-intervention phases (adjusted odds ratio [aOR] 1.59; 95% confidence interval [CI] 0.91 to 2.77). However, among high-risk women in the intervention phase, aspirin prophylaxis was significantly associated with a 41% reduction in the incidence of preterm PE (aOR 0.59; 95%CI 0.37 to 0.92). Additionally, it correlated with 54%, 55% and 64% reduction in the incidence of PE with delivery at <34 weeks (aOR 0.46; 95%CI 0.23 to 0.93), spontaneous preterm birth <34 weeks (aOR 0.45; 95%CI 0.22 to 0.92) and perinatal death (aOR 0.34; 95%CI 0.12 to 0.91), respectively. There was no significant between-group difference in the incidence of aspirin-related severe adverse events. CONCLUSIONS: The implementation of the screen-and-prevent strategy for preterm PE is not associated with a significant reduction in the incidence of preterm PE. However, low-dose aspirin effectively reduces the incidence of preterm PE by 41% among high-risk women. The screen-and-prevent strategy for preterm PE is highly accepted by a diverse group of women from various ethnic backgrounds beyond the original population where the strategy was developed. These findings underpin the importance of the widespread implementation of the screen-and-prevent strategy for preterm PE on a global scale.

A Finite Element Model for Simulating Stress Responses of Permeable Road Pavement.

Permeable road pavements, due to their open-graded design, suffer from low structural strength, restricting their use in areas with light traffic volume and low bearing capacity. To expand application of permeable road pavements, accurate simulation of stress parameters used in pavement design is essential. A 3D finite element (3D FE) model was developed using ABAQUS/CAE 2021 to simulate pavement stress responses. Utilizing a 53 cm thick permeable road pavement and a 315/80 R22.5 wheel as prototypes, the model was calibrated and validated, with its accuracy confirmed through t-test statistical analysis. Simulations of wheel speeds at 11, 15, and 22 m/s revealed significant impact on pavement depths of 3 cm and 8 cm, while minimal effects were observed at depths of 13 cm and 33 cm. Notably, stress values at a depth of 3 cm with 15 m/s speed in the open-graded asphalt concrete (OGFC) surface layer exceeded those at the speed of 11 m/s, while at a depth of 8 cm in the porous asphalt concrete (PAC) base layer, an opposite performance was observed. This may be attributed to the higher elastic modulus of the OGFC surface layer, which results in different response trends to velocity changes. Overall, lower speeds increase stress responses and prolong action times for both layers, negatively affecting pavement performance. Increasing the moduli of layers is recommended for new permeable road pavements for low-speed traffic. Furthermore, considering the effects of heavy loads and changes in wheel speed, the recommended design depth for permeable road pavement is 30 cm. These conclusions provide a reference for the design of permeable road pavements to address climate change and improve performance.

Prenatal Ultrasound Markers of Isolated Total Anomalous Pulmonary Venous Return and a Sequential Approach to Reach Diagnosis.

This article comprehensively reviews the literature concerning prenatal ultrasound findings of isolated total anomalous pulmonary venous return (TAPVR) and the application of specific sonographic markers to differentiate among the TAPVR types. These markers can be categorized as direct and indirect, based on either morphological features or hemodynamic changes in TAPVR. Indirect markers include the ventricular disproportion, an increased distance between the left atrium (LA) and the descending aorta, as well as the dilatation of superior vena cava or coronary sinus for supracardiac or cardiac TAPVR, along with abnormal pulmonary venous spectral Doppler patterns. Direct markers predominantly focus on the absence of a connection between the pulmonary veins and the LA. Some direct markers are specific to certain TAPVR types, such as the vertical vein. Diagnosing isolated TAPVR can pose challenges, but following a sequential approach can improve detection rates and outcomes. In cases with equivocal findings, additional follow-ups are recommended. The sequential approach described in the current article provides a step-wise methodology and sonographic markers for prenatal diagnosis of TAPVR, which can be utilized by fetal-maternal medicine specialists, obstetricians, and radiological technicians to ensure timely interventions.

Prophylactic Versus Reactive Megestrol Acetate Use for Critical Body Weight Loss in Patients with Pharyngeal and Laryngeal Squamous Cell Carcinoma Undergoing Concurrent Chemoradiotherapy.

This study compared the effects of megestrol acetate (MA) prophylactic (p-MA) versus reactive (r-MA) use for critical body-weight loss (>5% from baseline) during concurrent chemoradiotherapy (CCRT) in patients with advanced pharyngolaryngeal squamous cell carcinoma (PLSCC).Patients receiving CCRT alone in two phase-II trials were included for analyses. Both the p-MA and r-MA cohorts received the same treatment protocol at the same institution, and the critical body-weight loss, survival, and adverse event profiles were compared.The mean (SD) weight loss was 5.1% (4.7%) in the p-MA cohort (n = 54) vs. 8.1% (4.6%) in the r-MA cohort (n = 50) (p = .001). The percentage of subjects with body-weight loss >5% was 42.6% in the p-MA cohort vs. 68.0% in the r-MA cohort (p = .011). Tube feeding was needed in 22.2% of p-MA vs. 62.0% of r-MA patients (p < .001). Less neutropenia (26.0% vs. 70.0% [p < .001]) and a shorter duration of grade 3-4 mucositis (2.4 ± 1.4 vs. 3.6 ± 2.0 wk [p = .009]) were observed with p-MA treatment. Disease-specific survival, locoregional control, or distant metastasis-free survival did not differ. Less competing mortality from secondary primary cancer resulted in a better overall survival trend in the p-MA cohort.p-MA may reduce body-weight loss and improve adverse event profiles during CCRT for patients with PLSCC.

Unique clinical and electrophysiological features in the peripheral nerve system in patients with sialidosis - a case series study.

BACKGROUND: To investigate the peripheral nervous system involvement in S sialidosis with typical features of myoclonus, seizure, and giant waves in somatosensory evoked potentials suggesting hyperexcitability in the central nervous system. METHODS: The clinical presentation of patients with genetically confirmed sialidosis was recorded. Neurophysiological studies, including nerve conduction studies (NCSs), F-wave studies, and needle electromyography (EMG), were performed on these patients. RESULTS: Six patients (M/F: 2:4) were recruited. In addition to the classical presentation, intermittent painful paresthesia was noted in four patients, and three of whom reported it as the earliest symptom. In the NCSs, one patient had reduced compound muscle action potential amplitudes in the right ulnar nerve, while another patient had prolonged distal motor latency in the bilateral tibial and peroneal nerves. Prolonged F-wave latency (83.3%), repeater F-waves (50%), and neurogenic polyphasic waves in EMG (in 2 out of 3 examined patients) were also noted. Interestingly, a very late response was noted in the F-wave study of all patients, probably indicating lesions involving the proximal peripheral nerve or spinal cord. CONCLUSION: In addition to the central nervous system, the peripheral nervous system is also involved in sialidosis, with corresponding clinical symptoms. Further study on these phenomena is indicated.

Postoperative radiotherapy versus surgery alone in pN1 oral cavity cancer patients: A meta-analysis.

Objectives: The aim of this meta-analysis is to evaluate the potential benefits of postoperative radiotherapy (PORT) in patients with pN1 oral cavity squamous cell carcinoma. Methods: A literature search through major databases was conducted until January 2023. The adjusted hazard ratio (aHR) or risk ratio (RR) with 95% confidence intervals (CIs) of different survival outcomes were extracted and pooled. Results: Ten studies published between 2005 and 2022, with a pooled patient population of 2888, were included in this meta-analysis. Due to differences in study design and reported outcomes, the studies were categorized into distinct groups. In pN1 patients without extranodal extension (ENE), PORT was associated with a significant improvement in overall survival (OS) (aHR 0.76, 95% CI: 0.61-0.94). In pN1 patients without ENE and positive margins, PORT improved OS (aHR 0.71, 95% CI: 0.56-0.89) and was associated with a lower regional recurrence rate (RR 0.35, 95% CI: 0.15-0.83). However, in pN1 patients without ENE, positive margins, perineural invasion, and lymphovascular invasion, there were no significant differences observed between the PORT and observation groups in either 5-year OS (RR 0.48, 95% CI: 0.07-3.41) or 5-year disease-free survival (RR 0.37, 95% CI: 0.07-2.06). Conclusions: The current study demonstrated that PORT has the potential to improve OS in pN1 disease. However, the decision of whether to administer PORT still hinges on diverse clinical scenarios, and additional research is necessary to furnish a more conclusive resolution. Level of Evidence: 2.

Utility of CT Radiomics and Delta Radiomics for Survival Evaluation in Locally Advanced Nasopharyngeal Carcinoma with Concurrent Chemoradiotherapy.

BACKGROUND: A high incidence rate of nasopharyngeal carcinoma (NPC) has been observed in Southeast Asia compared to other parts of the world. Radiomics is a computational tool to predict outcomes and may be used as a prognostic biomarker for advanced NPC treated with concurrent chemoradiotherapy. Recently, radiomic analysis of the peripheral tumor microenvironment (TME), which is the region surrounding the gross tumor volume (GTV), has shown prognostic usefulness. In this study, not only was gross tumor volume (GTVt) analyzed but also tumor peripheral regions (GTVp) were explored in terms of the TME concept. Both radiomic features and delta radiomic features were analyzed using CT images acquired in a routine radiotherapy process. METHODS: A total of 50 patients with NPC stages III, IVA, and IVB were enrolled between September 2004 and February 2014. Survival models were built using Cox regression with clinical factors (i.e., gender, age, overall stage, T stage, N stage, and treatment dose) and radiomic features. Radiomic features were extracted from GTVt and GTVp. GTVp was created surrounding GTVt for TME consideration. Furthermore, delta radiomics, which is the longitudinal change in quantitative radiomic features, was utilized for analysis. Finally, C-index values were computed using leave-one-out cross-validation (LOOCV) to evaluate the performances of all prognosis models. RESULTS: Models were built for three different clinical outcomes, including overall survival (OS), local recurrence-free survival (LRFS), and progression-free survival (PFS). The range of the C-index in clinical factor models was (0.622, 0.729). All radiomics models, including delta radiomics models, were in the range of (0.718, 0.872). Among delta radiomics models, GTVt and GTVp were in the range of (0.833, 0.872) and (0.799, 0.834), respectively. CONCLUSIONS: Radiomic analysis on the proximal region surrounding the gross tumor volume of advanced NPC patients for survival outcome evaluation was investigated, and preliminary positive results were obtained. Radiomic models and delta radiomic models demonstrated performance that was either superior to or comparable with that of conventional clinical models.

Prenatal Ultrasound Imaging of Orofacial Clefts: A Pictorial Essay.

Orofacial clefts (OFCs), including cleft lip (CL), cleft palate (CP), and CL with palate (CL/P), are relatively common congenital birth defects occurring in approximately 1 in 500 to 1 in 2500 live births. Detecting OFCs during prenatal ultrasound screening is crucial for informed decision-making and multidisciplinary medical care. This review provides a practical guide for routine and advanced screening for OFCs during mid-pregnancy. The Maarse classification system facilitates effective communication among the multidisciplinary team, categorizing OFCs into five types. Basic ultrasound views encompass coronal, sagittal, and axial imaging of the face and hard palate. Additional visualization techniques are employed in case of suspected anomalies during the initial screening. Advanced ultrasound views provided by the expert in prenatal OFC diagnosis include imaging of the posterior edge of the hard palate and the posterior part of the soft palate. Detected OFCs exhibit a range of severity and affect different structures, underscoring the importance of accurate detection and classification for appropriate treatment planning. Implementing a standardized screening protocol for OFCs is essential. By enhancing detection rates and enabling early diagnosis, prenatal ultrasound screening contributes to improved patient outcomes and facilitates timely intervention by the multidisciplinary team. In conclusion, this review emphasizes the significance of standardized protocols and specialized techniques for prenatal ultrasound screening of OFCs. Early detection and classification of these malformations play a vital role in comprehensive management, ensuring that affected individuals and their families receive the appropriate care and support they need.

Clinical characteristics and prognostic impact of direct distant organ metastasis in colorectal cancer.

BACKGROUND: Colorectal cancer (CRC) is the third most common type of cancer worldwide, and distant metastasis is frequently noted at diagnosis or follow-up. Notably, some patients with CRC can present with distant organ metastasis without any nodal involvement, which was defined as direct distant organ metastasis (DDOM). In this study, we evaluated the prognostic significance of DDOM for patients with CRC. METHODS: This study included 325 patients who had undergone primary colorectal cancer resection between August 2008 and December 2021. The patients with and without DDOM were compared (Kaplan-Meier analysis) in terms of overall survival (OS) and time to recurrence. Furthermore, the patients' clinicopathological risk factors and protective factors were analyzed (multivariate Cox proportional hazards model). RESULTS: Of the 325 patients, 65 (20%) had DDOM (Direct+ group) and 260 (80%) did not (Direct- group). The Kaplan-Meier analysis revealed that OS was significantly better in the Direct+ group than in the Direct- group (p < 0.01). A subgroup analysis by CRC stage was performed; for the patients with non-stage-IV CRC, the rate of OS was significantly higher in the Direct+ group than in the Direct- group (p = 0.02). However, DDOM did not affect the OS of the patients with stage IV CRC. The multivariate analysis indicated DDOM, left colon tumor location, and postoperative adjuvant chemotherapy were significant protective factors for disease-related mortality in the patients with non-stage-IV CRC; by contrast, body mass index, curative resection, and postoperative adjuvant chemotherapy were identified to be significant protective factors in the patients with stage IV CRC. CONCLUSIONS: DDOM appears to be significantly associated with improved OS in patients with non-stage-IV CRC but not in those with stage IV CRC. Furthermore, the time to cancer recurrence may not vary significantly between patients with DDOM and those without it.

Miltefosine reduces coxsackievirus B3 lethality of mice with enhanced STAT3 activation.

Coxsackievirus B3 (CVB3), one serotype of enteroviruses, can induce fatal myocarditis and hepatitis in neonates, but both treatment and vaccine are unavailable. Few reports tested antivirals to reduce CVB3. Several antivirals were developed against other enterovirus serotypes, but these antivirals failed in clinical trials due to side effects and drug resistance. Repurposing of clinical drugs targeting cellular factors, which enhance viral replication, may be another option. Parasite and cancer studies showed that the cellular protein kinase B (Akt) decreases interferon (IFN), apoptosis, and interleukin (IL)-6-induced STAT3 responses, which suppress CVB3 replication. Furthermore, miltefosine, the Akt inhibitor used in the clinic for parasite infections, enhances IL-6, IFN, and apoptosis responses in treated patients, suggesting that miltefosine could be the potential antiviral for CVB3. This study was therefore designated to test the antiviral effects of miltefosine against CVB3 in vitro and especially, in mice, as few studies test miltefosine in vitro, but not in vivo. In vitro results showed that miltefosine inhibited viral replication with enhanced activation of the cellular transcription factor, STAT3, which is reported to reduce CVB3 both in vitro and in mice. Notably, STAT3 knockdown abolished the anti-CVB3 activity of miltefosine in vitro. Mouse studies demonstrated that miltefosine pretreatment reduced CVB3 lethality of mice with decreased virus loads, organ damage, and apoptosis, but enhanced STAT3 activation. Miltefosine could be prophylaxis for CVB3 by targeting Akt to enhance STAT3 activation in the mechanism, which is independent of IFN responses and hardly reported in pathogen infections.

Collagen patch cover facilitates recovery of bowel function after laparoscopic colectomy.

BACKGROUND: Numerous factors can influence bowel movement recovery and anastomotic healing in colorectal surgery, and poor healing can lead to severe complications and increased medical expenses. Collagen patch cover (CPC) is a promising biomaterial that has been demonstrated to be safe in animal models and has been successfully applied in various surgical procedures in humans. This study. METHODS: A retrospective review of medical records from July 2020 to June 2022 was conducted to identify consecutive patients who underwent laparoscopic colectomy. Patients who received CPC at the anastomotic site were assigned to the collagen group, whereas those who did not receive CPC were assigned to the control group. RESULTS: Data from 241 patients (collagen group, 109; control group, 132) were analyzed. Relative to the control group, the collagen group exhibited a faster recovery of bowel function, including an earlier onset of first flatus (2.93 days vs. 3.43 days, p < 0.01), first defecation (3.73 days vs. 4.18 days, p = 0.01), and oral intake (4.30 days vs. 4.68 days, p = 0.04). CPC use was also associated with lower use of postoperative intravenous analgesics. The complication rates in the two groups did not differ significantly. CONCLUSIONS: CPCs can be safely and easily applied to the anastomotic site during laparoscopic colectomy, and can accelerate bowel movement recovery. Further studies on the effectiveness of CPCs in colorectal surgery involving larger sample sizes are required. CLINICAL TRIAL REGISTRATION: ClinicalTrials.gov registration number: NCT05831956 (26/04/2023).

PROX1 interaction with α-SMA-rich cancer-associated fibroblasts facilitates colorectal cancer progression and correlates with poor clinical outcomes and therapeutic resistance.

BACKGROUND: The tumor microenvironment (TME) plays a vital role in tumor progression through intricate molecular interactions. Cancer-associated fibroblasts (CAFs), notably those expressing alpha-smooth muscle actin (α-SMA) or myofibroblasts, are instrumental in this context and correlate with unfavorable outcomes in colorectal cancer (CRC). While several transcription factors influence TME, the exact regulator causing CAF dysregulation in CRC remains elusive. Prospero Homeobox 1 (PROX1) stands out, as its inhibition reduces α-SMA-rich CAF activity. However, the therapeutic role of PROX1 is debated due to inconsistent study findings. METHODS: Using the ULCAN portal, we noted an elevated PROX1 level in advanced colon adenocarcinoma, linking to a poor prognosis. Assays determined the impact of PROX1 overexpression on CRC cell properties, while co-culture experiments spotlighted the PROX1-CAF relationship. Molecular expressions were validated by qRT-PCR and Western blots, with in vivo studies further solidifying the observations. RESULTS: Our study emphasized the connection between PROX1 and α-SMA in CAFs. Elevated PROX1 in CRC samples correlated with increased α-SMA in tumors. PROX1 modulation influenced the behavior of specific CRC cells, with its overexpression fostering invasiveness. Kaplan-Meier evaluations demonstrated a link between PROX1 or α-SMA and survival outcomes. Consequently, PROX1, alone or with α-SMA, emerges as a CRC prognostic marker. Co-culture and animal experiments further highlighted this relationship. CONCLUSION: PROX1 appears crucial in modulating CRC behavior and therapeutic resistance within the TME by influencing CAFs, signifying the combined PROX1/α-SMA gene as a potential CRC prognostic marker. The concept of developing inhibitors targeting this gene set emerges as a prospective therapeutic strategy. However, this study is bound by limitations, including potential challenges in clinical translation, a focused exploration on PROX1/α-SMA potentially overlooking other significant molecular contributors, and the preliminary nature of the inhibitor development proposition.

Alternative therapy for acute appendicitis with appendicolith using traditional Chinese medicine: A case report.

INTRODUCTION: Treating older patients with acute appendicitis with multiple underlying diseases is a challenging situation in the clinical setting. Throughout the history of East Asian medicine, many texts have noted the use of herbal decoctions to successfully treat symptoms associated with appendicitis, thereby providing an alternative management strategy for treating frail patients with acute appendicitis. CASE PRESENTATION: This report presents the case of a 93-year-old male diagnosed with acute appendicitis with appendicolith who was unsuitable for surgical intervention due to poor lung condition and prolonged prothrombin time caused by Apixaban. By receiving complementary therapy consisting of traditional Chinese medicine (TCM) and antibiotics, he recovered successfully. DISCUSSION: In the early stage of acute appendicitis, infection control and gastrointestinal mobility are the most important factors to consider. Scientific research has demonstrated that many herbs used in TCM formulas possess anti-inflammatory, anti-oxidative and immune attenuation effects. For many patients who are unsuitable for surgical intervention due to unfavorable conditions, such as the prolonged prothrombin time presented in this case, complementary treatment with TCM offers adjuvant therapeutical effects associated with infection control, and improvement of the gastrointestinal environment and function of elderly patients.

Unraveling the Role of miR-200b-3p in Attention-Deficit/Hyperactivity Disorder (ADHD) and Its Therapeutic Potential in Spontaneously Hypertensive Rats (SHR).

Attention-deficit/hyperactivity disorder (ADHD) is a prevalent neurodevelopmental disorder in children with unknown etiology. Impaired learning ability was commonly reported in ADHD patients and has been associated with dopamine uptake in the striatum of an animal model. Another evidence also indicated that micro-RNA (miR)-200b-3p is associated with learning ability in various animal models. However, the association between miR-200b-3p and ADHD-related symptoms remains unclear. Therefore, the current study investigated the role of miR-200b-3p in ADHD-related symptoms such as inattention and striatal inflammatory cytokines. To verify the influence of miR-200b-3p in ADHD-related symptoms, striatal stereotaxic injection of miR-200b-3p antagomir (AT) was performed on spontaneously hypertensive rats (SHR). The antioxidant activity and expressions of miR-200b-3p, slit guidance ligand 2 (Slit2), and inflammatory cytokines in the striatum of SHR were measured using quantitative real-time polymerase chain reaction (RT-qPCR), immunohistochemistry (IHC), immunoblotting, and enzyme-linked immunosorbent assay (ELISA). The spontaneous alternation of SHR was tested using a three-arm Y-shaped maze. The administration of miR-200b-3p AT or taurine significantly decreased striatal tumor necrosis factor (TNF)-α, interleukin (IL)-1ß, and IL-6 in SHR, along with increased super-oxide dismutase (SOD) and glutathione peroxidase (GSH-Px) activities and significantly higher spontaneous alternation. In this paper, we show that miR-200b-3p AT and taurine alleviates ADHD-related symptoms in SHR. These findings provide insights into ADHD's molecular basis and suggest miR-200b-3p as a potential therapeutic target. Concurrently, this study also suggests broad implications for treating neurodevelopmental disorders affecting learning activity such as ADHD.

Predicting the therapeutic response to valproic acid in childhood absence epilepsy through electroencephalogram analysis using machine learning.

Childhood absence epilepsy (CAE) is a common type of idiopathic generalized epilepsy, manifesting as daily multiple absence seizures. Although seizures in most patients can be adequately controlled with first-line antiseizure medication (ASM), approximately 25 % of patients respond poorly to first-line ASM. In addition, an accurate method for predicting first-line medication responsiveness is lacking. We used the quantitative electroencephalogram (QEEG) features of patients with CAE along with machine learning to predict the therapeutic effects of valproic acid in this population. We enrolled 25 patients with CAE from multiple medical centers. Twelve patients who required additional medication for seizure control or who were shifted to another ASM and 13 patients who achieved seizure freedom with valproic acid within 6 months served as the nonresponder and responder groups. Using machine learning, we analyzed the interictal background EEG data without epileptiform discharge before ASM. The following features were analyzed: EEG frequency bands, Hjorth parameters, detrended fluctuation analysis, Higuchi fractal dimension, Lempel-Ziv complexity (LZC), Petrosian fractal dimension, and sample entropy (SE). We applied leave-one-out cross-validation with support vector machine, K-nearest neighbor (KNN), random forest, decision tree, Ada boost, and extreme gradient boosting, and we tested the performance of these models. The responders had significantly higher alpha band power and lower delta band power than the nonresponders. The Hjorth mobility, LZC, and SE values in the temporal, parietal, and occipital lobes were higher in the responders than in the nonresponders. Hjorth complexity was higher in the nonresponders than in the responders in almost all the brain regions, except for the leads FP1 and FP2. Using KNN classification with theta band power in the temporal lobe yielded optimal performance, with sensitivity of 92.31 %, specificity of 76.92 %, accuracy of 84.62 %, and area under the curve of 88.46 %.We used various EEG features along with machine learning to accurately predict whether patients with CAE would respond to valproic acid. Our method could provide valuable assistance for pediatric neurologists in selecting suitable ASM.

The role of thrombomodulin in modulating ITGB3 expression and its implications for triple-negative breast cancer progression.

Triple-negative breast cancer (TNBC) is the most aggressive subtype of breast cancer (BC) compared to other BC subtypes in clinical settings. Currently, there are no effective therapeutic strategies for TNBC treatment. Therefore, there is an urgent need to identify suitable biomarkers or therapeutic targets for TNBC patients. Thrombomodulin (TM) plays a role in cancer progression and metastasis in many different cancers. However, the role of TM in TNBC is not yet fully understood. First, silenced-TM in MDA-MB-231 cells caused an increase in proliferative and metastatic activity. In contrast, overexpression of TM in Hs578T cells caused a reduction in proliferation, invasion, and migration rate. Using RNA-seq analysis, we found that Integrin beta 3 (ITGB3) expression may be a downstream target of TM. Furthermore, we found an increase in ITGB3 levels in TM-KD cells by QPCR and western blot analysis but a decrease in ITGB3 levels in TM-overexpressing cells. We found phospho-smad2/3 levels were increased in TM-KD cells but decreased in TM-overexpressing cells. This implies that TM negatively regulates ITGB3 levels through the activation of the smad2/3 pathway. Silencing ITGB3 in TM-KD cells caused a decrease in proliferation and migration. Finally, we found that higher ITGB3 levels were correlated with poor overall survival and relapse-free survival in patients with TNBC. Our results indicated a novel regulatory relationship between TM and ITGB3 in TNBC.
