INTRODUCTION: The investigation of brainwave changes during the recovery process of unilateral spatial neglect (USN) has garnered considerable attention in recent years. This paper presents an updated overview of the evolving brainwave patterns during USN rehabilitation, aiming to predict clinical outcomes and guide the selection of effective recovery strategies.
METHODS: A systematic review was conducted, encompassing English literature published up to June 2024. Databases including PubMed, Web of Science, and clinical trials were utilized. The included studies assessed brainwaves using electroencephalography (EEG) in at least one group with USN. However, the diverse nature of these studies posed challenges for a quantitative synthesis.
RESULTS: The final quantitative synthesis comprised 36 studies, incorporating a total of 4517 data points. The analysis revealed abnormalities in alpha, beta, and gamma brainwave activity, along with alterations in the functional monitoring of the alpha band during USN rehabilitation. Additionally, reductions were observed in specific brainwave components such as P1, N1, P2, P300, early directing attention negativity (EDAN), late directing attention positivity (LDAP), and contingent negative variation (CNV). However, findings regarding measures of synchrony, connectivity, and evoked responses across different frequency bands exhibited variability.
CONCLUSIONS: Various indicators of brainwave activity displayed changes at different stages of post-stroke neglect rehabilitation, highlighting the significance of neural network dysfunction in this process. Nonetheless, due to the diversity of the studies, further investigation is necessary to achieve a more comprehensive understanding in future research endeavors.
The particular interest of this study is the use of ultrasound to evaluate a child's optic nerve sheath diameter (ONSD), or the size of the covering around the nerve behind the eye. This covering expands when there is a higher than normal pressure inside the head. The group of interest on which this study focuses is the children with cerebrospinal shunts that drain extra fluid from their heads to other parts of the body (abdomen, heart, lungs) because the brain cannot drain all of the fluid like normal. When these shunts malfunction or fail, this can cause a backup of fluid in the brain, and raise the intracranial pressure (ICP) inside the skull. Depending on the degree of pressure buildup, this can be a surgical emergency due to pressure on the brain. Currently, computed tomography (CT) scans or magnetic resonance imaging (MRI) scans are used to diagnose the condition, but a quick screening tool, such as use of ultrasound to screen for elevated ICP in the emergency department, would be of great benefit to the patients to expedite care. Previous studies have explored the use of bedside ultrasound to evaluate the optic nerve sheath diameter in children with shunts. However, to date, there have been no reported prospective observational studies that compared before and after ultrasound measurements of the ONSD in patients in whom shunt failure is diagnosed and treated. Of note, this study is observational and the measurements taken with the ultrasound machine will not be used for clinical decision making. The measurements in this study will have no clinical impact on patient care. The use of ultrasound to measure the ONSD is an already accepted application of ultrasound.
Participants will receive an initial dose of 80 mg of 3,4-methylenedioxymethamphetamine (MDMA) and an optional supplemental dose of 40 mg MDMA during the first Experimental Session. In the second and third Experimental Sessions, the participant will receive an initial dose of 120 mg MDMA and an optional supplemental dose of 40 mg MDMA.
Under local anaesthesia, the femoral artery was punctured and 6F sheath was inserted. Splenic artery was catheterized using 4- or 5-F catheters (Cobra C2 cat or Simmons II catheter Imager-Boston Scientific Natick, Massachusetts). Embolization was done using Embospheres (Biosphere Medical, Rockland, MA) 700-900 μ in diameter.
There is a pressing need to develop biomarkers for renal disease, which might assist in diagnosis and prognosis and might provide endpoints for clinical trials of drugs designed to slow progression of renal insufficiency. We propose to study potential biomarkers in five populations. First, we will study remittive therapy for glomerular disease (sample size up to 40), enrolling children with idiopathic nephrotic syndrome (N=20) and adults with minimal change, focal segmental glomerulosclerosis, and collapsing glomerulopathy (N=20). We will collect periodic urine samples as these patients receive remittive therapy with glucocorticoids or other agents. We will also study up to 10 healthy adult volunteers. We will carry out targeted urine proteomic studies, measuring levels of glomerular cell markers and cytokines, and we will profile urine proteins using mass spectrometry. Our goals are to identify markers of particular disease entities and of steroid responsiveness and to explore whether biomarkers contribute to the histologic sub-classification of these diseases. Second, we will study up to 40 adults with progressive chronic kidney disease of various etiologies and glomerular filtration rate \<60 ml/min/1.73m2. We will study blood and urine samples, using both targeted and profiling approaches. Our goal is to identify biomarkers that correlate with progressive loss of glomerular filtration function, which is a functional correlate of progressive renal fibrosis. Third, we will study up to 40 adults, primarily with diabetic nephropathy, who start or stop angiotensin antagonist therapy (angiotensin converting enzyme inhibitors or angiotensin receptor blockers) and compare urine proteomic profiles on therapy and off therapy (4 week interval). Our goal is to identify potential biomarkers that correlate with the beneficial anti-fibrotic effects of these agents. Fourth, we wish to define possible sex differences in urine exosome proteins, obtained from healthy volunteers, who are hospitalized for six days for administration of a standard diet and collection of research urine samples. Fifth, we wish to determine whether salt intake influences urine exosome proteins, obtained from healthy volunteers. These subjects will be hospitalized for 12 days during which time they will be placed sequentially on a high salt diet and a low salt diet, with collection of research urine samples and blood pressure monitoring. Proteomic analysis in these studies will take several approaches, including mass spectrometry of urinary peptides, analysis of urinary exosomes, and immunologic detection and quantification of candidate proteins in urine and blood.
BACKGROUND AND PURPOSE: Delirium is a common mental disorder after adult cardiovascular surgery. Fifteen to 23% of patients undergoing cardiovascular surgery and cardiomyopathy experience delirium, and the efficacy of treatment interventions for delirium has been consistently unsatisfactory.
METHODS: A total of 729 patients who underwent cardiovascular surgery were randomly allocated into a training set and a validation set. A nomogram was developed using a logistic regression model to predict the incidence of delirium following cardiovascular surgery. The validity of the model was assessed by determining the receiver operating characteristic (ROC) curve, calculating the area under the ROC curve (AUROC), performing a calibration plot, and executing a decision curve analysis. This model was internally validated using the bootstrap method.
RESULTS: Postoperative delirium (POD) occurred in 165 cases (22.6%) among the 729 patients. Predictors included age, transient ischemic attack, length of preoperative stay, preoperative left ventricular injection fraction and N-terminal pro-B-type natriuretic peptide level, and intraoperative infusion of dexmedetomidine and human fibrinogen. The nomogram showed sufficient differentiation and calibration (AUROC = 0.754, 95% confidence interval = 0.703-0.804). The calibration graphs showed that the predictive values of the nomogram were in agreement with the actual values. The analysis of the training and validation sets suggested that the model possessed specific clinical significance.
CONCLUSIONS: In summary, the predictive model consists of seven factors that can roughly predict the occurrence of POD in patients who undergo cardiovascular surgery.
BACKGROUND: Delirium is a common complication during hospitalization. Its consequences are severe, including reduced function, delayed rehabilitation, dementia, institutionalization, and death. Assessing delirium in neurological patients can be challenging due to the impact of neurological deficits. Therefore, the aim was to investigate the agreement between 2 delirium screening tools, factors associated with delirium, and assessing delirium in neurological patients. METHODS: This prospective observational study was conducted in 2 neurological units, using daily delirium screening. Intensive Care Delirium Screening Checklist and 2 versions of the Confusion Assessment Method were used to asses delirium in adult patients without baseline dementia, alcohol/drug detoxification, or palliative care. Descriptive analyses determined the number of delirium scores, and the analytical analyses were logistic regressions and a κ coefficient. RESULTS: The agreement between the screening tools was found to be substantial (κ = 0.71). Logistic regression analysis showed that the risk factors for a positive delirium screening were home care before admission (Confusion Assessment Method: odds ratio [OR], 4.21 [95% confidence interval (CI), 1.67-10.63]; Intensive Care Delirium Screening Checklist: OR, 6.14 [95% CI, 2.85-13.23]) and aphasia/dysarthria (Confusion Assessment Method: OR, 4.9 [95% CI, 1.32-6.81]; Intensive Care Delirium Screening Checklist: OR, 2.76 [95% CI, 1.3-5.87]). In total, 18.7% (n = 20/107) of the screening scores were positive. Specifically, the Confusion Assessment Method showed positive scores for 13.0% (n = 14/107) of participants, whereas the Intensive Care Delirium Screening Checklist showed positive scores for 16.8% (n = 18/107). CONCLUSION: The screening tools had a substantial degree of agreement. Therefore, nurses can use both screening tools to detect delirium in patients with neurological disorders. However, care should be taken in patients with aphasia to avoid misclassification with the Brief-Confusion Assessment Method. Moreover, special attention should be directed toward patients with language difficulties such as aphasia/dysarthria and those who received home care services before admission. These areas warrant further investigation in clinical practice and future studies.
Patients receive cisplatin IV over 1 hour on day 1 and placebo PO BID on days 1-14. Cycles repeat every 21 days in the absence of disease progression or unacceptable toxicity.
Inflammation-induced choroidal neovascularization followed by the epithelial-mesenchymal transition (EMT) of retinal pigment epithelial cells (RPEs) is a cause of neovascular age-related macular degeneration (nAMD). RPE-derived myofibroblasts overproduce extracellular matrix, leading to subretinal fibrosis. We already have demonstrated that benzylphenylurea (BPU) derivatives inhibit the function of cancer-associated fibroblasts. Here, we investigated the anti-myofibroblast effects of BPU derivatives and examined such BPU activity on subretinal fibrosis. A BPU derivative, BPU17, exhibits the most potent anti-myofibroblast activity among dozens of BPU derivatives and inhibits subretinal fibrosis in a mouse model of retinal degeneration. Investigations with primary cultured RPEs reveal that BPU17 suppresses cell motility and collagen synthesis in RPE-derived myofibroblasts. These effects depend on repressing the serum response factor (SRF)/CArG-box-dependent transcription. BPU17 inhibits the expression of SRF cofactor, cysteine and glycine-rich protein 2 (CRP2), which activates the SRF function. Proteomics analysis reveals that BPU17 binds to prohibitin 1 (PHB1) and inhibits the PHB1-PHB2 interaction, resulting in mild defects in mitochondrial function. This impairment causes a decrease in the expression of CRP2 and suppresses collagen synthesis. Our findings suggest that BPU17 is a promising agent against nAMD and the close relationship between PHB function and EMT.

Study protocol After signing the informed consent form, the patients underwent an oral examination and answered about clinical information, oral pain scale, and the OHIP-14 questionnaire. The pain scale was graded between 0 (no pain) and 10 (maximum), Likert standard. There was also a drawing for the distribution of coded treatments, through a number taken by the patient from a manila envelope. After the orthodontic appliance installation session, each patient was instructed to use the coded treatment for the next 21 days, two gums after breakfast, after lunch and after dinner, totalizing 12 billion UFC of L brevis or placebo per day. The patient was provided with a diary to note the daily appearance of lesions and their evolution during the 21-day period, as well as the occurrence of any new symptoms (potential adverse effect), in addition to proof of the commitment assumed by the use of the tablets. After 21 days, each patient was reexamined by the author of the study, who collected the diaries and obtained information regarding the oral examination, oral pain scale, data on adherence to treatment and self-completion of the OHIP-14.

Statistical analysis Quantitative data are described with mean and standard deviation (or standard error of the mean) or median and range, while qualitative data are displayed with absolute and relative frequencies. Student's t-test was used for comparison of quantitative data between groups, Wilcoxon-Mann-Whitney (WMW) test being employed when the assumptions for that test were not met. Exact chi-square and Fisher´s exact test (FET) were used for categorical data. Treatment effect on OHIP-14 was analyzed using a Generalize Estimating Equations (GEE) model with Poisson distribution and log link, the predictors being treatment, time (beginning and end of treatment) and interaction treatment\*time. The analyses were performed with softwares GraphPrism version 4.0 and SPSS® (IBM SPSS statistics v18). Sample size was estimated using WinPEPI v11.65. The P value indicative of significance was \< 0.05. Because the final outcome was prevention or mitigation (not maintenance or augmentation) of undesirable symptoms, one-tailed tests were used for comparisons between groups respect to days without oral lesions, oral pain and OHIP-14 scores.
The detection of lymph node metastases is essential for breast cancer staging, although it is a tedious and time-consuming task where the sensitivity of pathologists is suboptimal. Artificial intelligence (AI) can help pathologists detect lymph node metastases, which could help alleviate workload issues. We studied how pathologists' performance varied when aided by AI. An AI algorithm was trained using more than 32 000 breast sentinel lymph node whole slide images (WSIs) matched with their corresponding pathology reports from more than 8000 patients. The algorithm highlighted areas suspicious of harboring metastasis. Three pathologists were asked to review a dataset comprising 167 breast sentinel lymph node WSIs, of which 69 harbored cancer metastases of different sizes, enriched for challenging cases. Ninety-eight slides were benign. The pathologists read the dataset twice, both digitally, with and without AI assistance, randomized for slide and reading orders to reduce bias, separated by a 3-week washout period. Their slide-level diagnosis was recorded, and they were timed during their reads. The average reading time per slide was 129 seconds during the unassisted phase versus 58 seconds during the AI-assisted phase, resulting in an overall efficiency gain of 55% ( P <0.001). These efficiency gains are applied to both benign and malignant WSIs. Two of the 3 reading pathologists experienced significant sensitivity improvements, from 74.5% to 93.5% ( P ≤0.006). This study highlights that AI can help pathologists shorten their reading times by more than half and also improve their metastasis detection rate.
The treatment group will employ the medical device of interest, ShotBlocker, bundled with the standard-of-care comfort measures of swaddling and sucrose during the administration of the Hepatitis B Immunization. A Masimo Rad-97 Oximeter probe will be applied to record a baseline and intervention physiologic response. There will be an Opt-In Video Recording option to assign a pain score (PIPP Scale) during the procedure by a blinded medical professional.
The present invention relates to 3α-triazole-oleanolic acid derivatives, a preparation method therefor, and the uses of said derivatives serving as hyaluronidase inhibitors and used for preparing anti-aging cosmetic products. Specifically, disclosed in the present invention are 3α-triazole-oleanolic acid derivatives having structures shown as general formula (I), and a preparation method therefor. In vitro activity tests show that the oleanolic acid derivatives have strong hyaluronidase inhibition activity and IC 50  being about 1-10 μg/mL, and the inhibitory activity is obviously stronger than that of oleanolic acid having IC 50  being about 56 μg/mL. Cell proliferation experiments show that the 3α-triazole-oleanolic acid derivatives have very low mammalian cell cytotoxicity. The 3α-triazole-oleanolic acid derivatives have good lipid solubility, are easily absorbed by skin tissues, and may be used as an anti-aging component for preparing cosmetic products. Further disclosed in the present invention are the uses of the 3α-triazole-oleanolic acid derivatives as a cosmetic component to prepare anti-skin aging facial masks.
On Track was the alternative program provided to males randomly assigned to the control group. On Track seeks to assist participants in identifying their aptitudes and preferences regarding their careers and their values associated with employment, and to provide tools to prepare them for the work setting and future job interviews. Participants learn how to identify attitudes, values, preferences, and challenges surrounding a career path, receive an understanding of the documents required for employment, and develop an initial employment strategy and action plan. Trained foster care agency staff deliver the curriculum to participating youth in two one-on-one sessions at agencies. Each session is one hour in length. Session two occurs 10 to 14 days after session one.
The investigators will conduct a prospective observational cohort study, separately deploying three separate LIRIC models (the general population, cirrhosis, and no_cirrhosis models) on retrospective de-identified EHR data of 44 HCOs in the USA, using the TriNetX federated network platform. LIRIC will generate a risk score for each individual. All risk-stratified individuals will be prospectively, electronically followed for up to 3-years to assess the primary end-point of HCC development. At the end of this period, model discrimination will be assessed, using the following metrics: AUROC, sensitivity, specificity, PPV/NPV. Risk scores generated by the model will be divided into quantiles. For each quantile, the investigators will evaluate the following: number of individuals in each quantile, number of HCC cases, PPV, NNS, SIR. Model calibration will be used for assessing the accuracy of estimates, based on the estimated to observed number of events. The model will dynamically re-evaluate all individual data every 6 months, re-classifying individuals (as needed).
BACKGROUND: Intravenous thrombolysis (IVT) before endovascular treatment (EVT) for acute ischemic stroke might induce intracerebral hemorrhages which could negatively affect patient outcomes. Measuring white matter lesions size using deep learning (DL-WML) might help safely guide IVT administration. We aimed to develop, validate, and evaluate a DL-WML volume on CT compared to the Fazekas scale (WML-Faz) as a risk factor and IVT effect modifier in patients receiving EVT directly after IVT.
METHODS: We developed a deep-learning model for WML segmentation on CT and validated with internal and external test sets. In a post hoc analysis of the MR CLEAN No-IV trial, we associated DL-WML volume and WML-Faz with symptomatic-intracerebral hemorrhage (sICH) and 90-day functional outcome according to the modified Rankin Scale (mRS). We used multiplicative interaction terms between WML measures and IVT administration to evaluate IVT treatment effect modification. Regression models were used to report unadjusted and adjusted common odds ratios (cOR/acOR).
RESULTS: In total, 516 patients from the MR CLEAN No-IV trial (male/female, 291/225; age median, 71 [IQR, 62-79]) were analyzed. Both DL-WML volume and WML-Faz are associated with sICH (DL-WML volume acOR, 1.78 [95%CI, 1.17; 2.70]; WML-Faz acOR, 1.53 95%CI [1.02; 2.31]) and mRS (DL-WML volume acOR, 0.70 [95%CI, 0.55; 0.87], WML-Faz acOR, 0.73 [95%CI 0.60; 0.88]). Only in the unadjusted IVT effect modification analysis WML-Faz was associated with more sICH if IVT was given (p = 0.046). Neither WML measure was associated with worse mRS if IVT was given.
CONCLUSION: DL-WML volume and WML-Faz had a similar relationship with functional outcome and sICH. Although more sICH might occur in patients with more severe WML-Faz receiving IVT, no worse functional outcome was observed.
CLINICAL RELEVANCE STATEMENT: White matter lesion severity on baseline CT in acute ischemic stroke patients has a similar predictive value if measured with deep learning or the Fazekas scale. Safe administration of intravenous thrombolysis using white matter lesion severity should be further studied.
KEY POINTS: White matter damage is a predisposing risk factor for intracranial hemorrhage in patients with acute ischemic stroke but remains difficult to measure on CT. White matter lesion volume on CT measured with deep learning had a similar association with symptomatic intracerebral hemorrhages and worse functional outcome as the Fazekas scale. A patient-level meta-analysis is required to study the benefit of white matter lesion severity-based selection for intravenous thrombolysis before endovascular treatment.
