Coupling High Hardness and Zn Affinity in Amorphous-Crystalline Diamond for Stable Zn Metal Anodes.

The highly reversible plating/stripping of Zn is plagued by dendrite growth and side reactions on metallic Zn anodes, retarding the commercial application of aqueous Zn-ion batteries. Herein, a distinctive nano dual-phase diamond (NDPD) comprised of an amorphous-crystalline heterostructure is developed to regulate Zn deposition and mechanically block dendrite growth. The rich amorphous-crystalline heterointerfaces in the NDPD endow modified Zn anodes with enhanced Zn affinity and result in homogeneous nucleation. In addition, the unparalleled hardness of the NDPD effectively overcomes the high growth stress of dendrites and mechanically impedes their proliferation. Moreover, the hydrophobic surfaces of the NDPD facilitate the desolvation of hydrate Zn2+ and prevent water-mediated side reactions. Consequently, the Zn@NDPD presents an ultrastable lifespan exceeding 3200 h at 5 mA cm-2 and 1 mAh cm-2. The practical application potential of Zn@NDPD is further demonstrated in full cells. This work exhibits the great significance of a chemical-mechanical synergistic anode modification strategy in constructing high-performance aqueous Zn-ion batteries.

Assessing the impact of early progressive mobilization on moderate-to-severe traumatic brain injury: a randomized controlled trial.

INTRODUCTION: Traumatic brain injury (TBI) is a major cause of neurodisability worldwide, with notably high disability rates among moderately severe TBI cases. Extensive previous research emphasizes the critical need for early initiation of rehabilitation interventions for these cases. However, the optimal timing and methodology of early mobilization in TBI remain to be conclusively determined. Therefore, we explored the impact of early progressive mobilization (EPM) protocols on the functional outcomes of ICU-admitted patients with moderate to severe TBI. METHODS: This randomized controlled trial was conducted at a trauma ICU of a medical center; 65 patients were randomly assigned to either the EPM group or the early progressive upright positioning (EPUP) group. The EPM group received early out-of-bed mobilization therapy within seven days after injury, while the EPUP group underwent early in-bed upright position rehabilitation. The primary outcome was the Perme ICU Mobility Score and secondary outcomes included Functional Independence Measure motor domain (FIM-motor) score, phase angle (PhA), skeletal muscle index (SMI), the length of stay in the intensive care unit (ICU), and duration of ventilation. RESULTS: Among 65 randomized patients, 33 were assigned to EPM and 32 to EPUP group. The EPM group significantly outperformed the EPUP group in the Perme ICU Mobility and FIM-motor scores, with a notably shorter ICU stay by 5.9 days (p < 0.001) and ventilation duration by 6.7 days (p = 0.001). However, no significant differences were observed in PhAs. CONCLUSION: The early progressive out-of-bed mobilization protocol can enhance mobility and functional outcomes and shorten ICU stay and ventilation duration of patients with moderate-to-severe TBI. Our study's results support further investigation of EPM through larger, randomized clinical trials. Clinical trial registration ClinicalTrials.gov NCT04810273 . Registered 13 March 2021.

The effect of sex, age, work experience, education, shift, and ward on nursing autonomy perceptions.

BACKGROUND: In Italy, cultural and professional nursing improvements are reached thanks to the university-based education which marks the clinical competency and the professional autonomy in nursing decision-making. OBJECTIVE: To highlight how Italian nurses perceived their nursing autonomy level in the main action-points highlighted in the Italian regulation law according to sex, age, work experience, education, shift and ward. METHODS: A cohort explorative study was carried out from September 2022 to January 2023 to highlight how Italian nurses perceived their nursing autonomy levels in the main action-points highlighted in the Italian regulation law for the nursing profession according to demographic characteristics, like: gender, age, work of experience, education, shift, ward employment. RESULTS: A total of 403 nurses were enrolled. Significant differences were recorded in: decision-making authority in patient care and shift (p≤0.001) and ward employment (p = 0.045); ability to initiate nursing interventions and education (p < 0.001) and ward employment (p = 0.011); collaboration and communication with healthcare team members and education (p < 0.001) and ward employment (p = 0.010); independence in clinical judgment and critical thinking and shift (p < 0.001); responsibility for the planning and evaluation of nursing care and education (p = 0.005) and shift (p = 0.002) and ward employment (p = 0.013); autonomy in professional development and continuing education and shift (p < 0.001) and ward employment (p < 0.001). CONCLUSIONS: The results highlighted the intricate world both of the healthcare surrounding and the abilities to act autonomously within the multiprofessional staff. Future studies will develop qualitative and phenomenological designs in order to better define in which fields nurses will act their professional autonomy.

Fusion of memristor and digital compute-in-memory processing for energy-efficient edge computing.

Artificial intelligence (AI) edge devices prefer employing high-capacity nonvolatile compute-in-memory (CIM) to achieve high energy efficiency and rapid wakeup-to-response with sufficient accuracy. Most previous works are based on either memristor-based CIMs, which suffer from accuracy loss and do not support training as a result of limited endurance, or digital static random-access memory (SRAM)-based CIMs, which suffer from large area requirements and volatile storage. We report an AI edge processor that uses a memristor-SRAM CIM-fusion scheme to simultaneously exploit the high accuracy of the digital SRAM CIM and the high energy-efficiency and storage density of the resistive random-access memory memristor CIM. This also enables adaptive local training to accommodate personalized characterization and user environment. The fusion processor achieved high CIM capacity, short wakeup-to-response latency (392 microseconds), high peak energy efficiency (77.64 teraoperations per second per watt), and robust accuracy (<0.5% accuracy loss). This work demonstrates that memristor technology has moved beyond in-lab development stages and now has manufacturability for AI edge processors.

Risk Factors for Isolated Sphenoid Sinusitis after Endoscopic Endonasal Transsphenoidal Pituitary Surgery.

(1) Background: Transsphenoidal pituitary surgery can be conducted via microscopic or endoscopic approaches, and there has been a growing preference for the latter in recent years. However, the occurrence of rare complications such as postoperative sinusitis remains inadequately documented in the existing literature. (2) Methods: To address this gap, we conducted a comprehensive retrospective analysis of medical records spanning from 2018 to 2023, focusing on patients who underwent transsphenoidal surgery for pituitary neuroendocrine tumors (formerly called pituitary adenoma). Our study encompassed detailed evaluations of pituitary function and MRI imaging pre- and postsurgery, supplemented by transnasal endoscopic follow-up assessments at the otolaryngology outpatient department. Risk factors for sinusitis were compared using univariate and multivariate logistic regression analyses. (3) Results: Out of the 203 patients included in our analysis, a subset of 17 individuals developed isolated sphenoid sinusitis within three months postoperation. Further scrutiny of the data revealed significant associations between certain factors and the occurrence of postoperative sphenoid sinusitis. Specifically, the classification of the primary tumor emerged as a notable risk factor, with patients exhibiting nonfunctioning pituitary neuroendocrine tumors with 3.71 times the odds of developing sinusitis compared to other tumor types. Additionally, postoperative cortisol levels demonstrated a significant inverse relationship, with lower cortisol levels correlating with an increased risk of sphenoid sinusitis postsurgery. (4) Conclusions: In conclusion, our findings underscore the importance of considering tumor classification and postoperative cortisol levels as potential predictors of postoperative sinusitis in patients undergoing transsphenoidal endoscopic pituitary surgery. These insights offer valuable guidance for clinicians in identifying at-risk individuals and implementing tailored preventive and management strategies to mitigate the occurrence and impact of sinusitis complications in this patient population.

Question prompt list intervention for patients with advanced cancer: a systematic review and meta-analysis.

BACKGROUND: Enhanced communication in end-of-life care (EOL) improves preparation and treatment decisions for patients with advanced cancer, affecting their quality of life at the end of life. Question prompt list (QPL) has been shown to enhance physician-patient communication in patients with cancer, but there is a lack of systematic review and meta-analysis for those with advanced cancer. Enhanced communication in end-of-life care improves preparation and treatment decisions for patients with advanced cancer, affecting their quality of life at the end of life. OBJECTIVE: To review the effectiveness of QPL intervention on physician-patient communication and health outcomes during consultation in patients with advanced cancer. METHODS: CINAHL, Embase, Scopus, and PsycINFO databases were undertaken using inclusion criteria for relevant articles up to August 2021. Pooled standardized mean difference (SMD) and 95% confidence intervals (CIs) were calculated using random-effects models. We used the Cochrane risk-of-bias assessment tool and modified Jadad scale to assess the quality of the studies. RESULTS: Seven RCTs with 1059 participants were included, of which six studies were eligible for the meta-analysis. The pooled meta-analysis results indicated that QPL in patients with advanced cancer had a significant positive effect on the total number of questions asked (SMD, 0.73; 95% CI, 0.28 to 1.18; I2 = 83%) and on the patients' expectations for the future (SMD, 0.67; 95% CI, 0.08 to 1.25; I2 = 88%). There were no significant improvements in health-related outcomes such as end of life, anxiety, and quality of life. CONCLUSIONS: Using QPL in advanced cancer consultations boosts patient questions which helps communication but not health-related indicators. Optimal results depend on full reading, but timing varies. Future research should examine the relationship between communication and health outcomes, including patient/physician behavior and social context.

Melanoma-like features in pediatric longitudinal melanonychia: A systematic review and meta-analysis.

BACKGROUND: Pediatric longitudinal melanonychia (LM) can exhibit atypical features that mimic red-flag signs for subungual melanoma in adults and lead to diagnostic uncertainty. Nail biopsy may be unnecessary if clinical inspection and dermoscopy suggest a benign nature. METHODS: We searched PubMed and Embase from inception to February 2023 for studies of any design reporting either the number or proportion of clinical and dermoscopic features in at least five children (≤18 years) with LM. Non-English articles, reviews, and abstracts were excluded. We performed a systematic review and meta-analysis to collate all existing data. RESULTS: A total of 1218 articles were screened and 24 studies with 1391 pediatric patients were included. Nevus was the most common diagnosis (86.3%). The most prevalent sites were fingernails (76.2%) and first digits (45.4%). Pooled proportions of common features were: dark-color bands (69.8%), multi-colored bands (47.6%), broad bandwidth (41.1%), pseudo-Hutchinson sign (41.0%), irregular patterns (38.1%), Hutchinson sign (23.7%), dots and globules (22.5%), nail dystrophy (18.2%), and triangular sign (10.9%). Outcomes included progression (widening or darkening, 29.9%), stability (23.3%), and spontaneous regression (narrowing or fading, 19.9%). Only eight cases of subungual melanoma in situ were reported, and no invasive melanomas were identified. CONCLUSION: Although atypical characteristics are common in pediatric LM, the probability of malignant transformation is exceedingly low. Appropriate evaluation and management of pediatric LM includes careful clinical and dermoscopic inspection with attention to benign features followed by long-term interval follow-up.

Inhibition of MMP8 effectively alleviates manic-like behavior and reduces neuroinflammation by modulating astrocytic CEBPD.

There is an intrinsic relationship between psychiatric disorders and neuroinflammation, including bipolar disorder. Ouabain, an inhibitor of Na+/K+-ATPase, has been implicated in the mouse model with manic-like behavior. However, the molecular mechanisms linking neuroinflammation and manic-like behavior require further investigation. CCAAT/Enhancer-Binding Protein Delta (CEBPD) is an inflammatory transcription factor that contributes to neurological disease progression. In this study, we demonstrated that the expression of CEBPD in astrocytes was increased in ouabain-treated mice. Furthermore, we observed an increase in the expression and transcript levels of CEBPD in human primary astrocytes following ouabain treatment. Transcriptome analysis revealed high MMP8 expression in human primary astrocytes following CEBPD overexpression and ouabain treatment. We confirmed that MMP8 is a CEBPD-regulated gene that mediates ouabain-induced neuroinflammation. In our animal model, treatment of ouabain-injected mice with M8I (an inhibitor of MMP8) resulted in the inhibition of manic-like behavior compared to ouabain-injected mice that were not treated with M8I. Additionally, the reduction in the activation of astrocytes and microglia was observed, particularly in the hippocampal CA1 region. Excessive reactive oxygen species formation was observed in ouabain-injected mice, and treating these mice with M8I resulted in the reduction of oxidative stress, as indicated by nitrotyrosine staining. These findings suggest that MMP8 inhibitors may serve as therapeutic agents in mitigating manic symptoms in bipolar disorder.

Validation and Measurement of Psychometric Properties of the "Nursing Work Environment Questionnaire" (NWE-q) in Italian Nurses.

Background: Evidence suggests that an optimal workplace is a physical, chemical, biological, organizational, social, and cultural condition in which each element contributes to the employer's condition. Purpose: To develop a nursing work environment questionnaire (NWE-Q). Patients and Methods: Convergent validity was measured using Pearson's correlation test. Internal consistency for each dimension of the Nursing Work Environment questionnaire (NWE-q) was performed thanks to the Cronbach's alpha coefficient. Construct validity and factor structure of the data were also assessed. Reliability was evaluated by measuring internal consistency. Interclass correlation coefficient and convergent validity were also assessed. Group validity was evaluated according to the sociodemographic characteristics collected using an independent t-test. Results: 376 nurses participated in this study. Both Kaiser-Meyer-Olkin measures of sampling adequacy were, and the Bartlett test of sphericity showed very strong evidence. Owing to oblique rotation, three main sub-dimensions were defined with good internal consistency for all items of the NWE-q (27 items), and each sub-dimension was registered. Very strong interclass correlations were assessed for the NWE-q total scores and for each sub-dimension, with the exception of the system dimensions, in which the interclass correlation showed a weak relationship. Strong positive evidence was found between the NWE-q for both the total and each sub-dimension correlated with the items of both the individual and organizational validated nursing performance questionnaires. Strong evidence was observed for both the organizational and system subdimensions according to shift and gender. Conclusion: The NWE-q was promptly completed in the online mode, and its scoring characteristics seemed to be more accessible and simpler to adopt.

Updates in the Management of Congenital Melanocytic Nevi.

Congenital melanocytic nevi (CMN) carry an increased risk of melanoma and may be disfiguring, and consensus regarding treatment recommendations is lacking. While clinical monitoring is the standard of care, many caregivers are interested in its removal to prevent psychosocial burden or to decrease risk. Although melanoma can occur regardless of CMN removal, there are a variety of treatments that may offer improved cosmesis or local symptom control, including surgical excision, laser therapy, and other superficially destructive techniques. Regardless of the selected management, these patients are monitored for ongoing melanoma risk. An extensive discussion with families regarding the risks and benefits of observation versus active intervention is essential. To facilitate these discussions, we herein summarize current CMN management strategies and considerations.

Effects of various functional monomers' reaction on the surface characteristics and bonding performance of polyetheretherketone.

PURPOSE: Polyetheretherketone (PEEK) is a new polymeric material that has received significant attention in dentistry because of its mechanical properties, biocompatibility, and aesthetics. However, the bonding performance of PEEK to other materials is not preferable. This study aimed to analyze the variations in the surface characteristics of PEEK under the chemical action of primers containing different functional monomers or polymers and to evaluate the bonding performance of PEEK and dental cement. METHODS: Disk-shaped PEEK samples were prepared by dental milling, blasting with alumina oxide, and covering with primers containing functional monomers or polymers. The surface characteristics of the samples were analyzed by microscopy and spectroscopy. The shear bond strength (SBS) between PEEK and dental cement, with and without thermocycling, was tested using a universal testing machine. Finally, the data were statistically analyzed and compared. RESULTS: Functional monomers or polymers were successfully bonded to the surface of PEEK. This treatment significantly improved its hydrophilicity and surface free energy (P < 0.05). The primer containing pentaerythritol triacrylate had the highest SBS without thermocycling (13.89 MPa). Meanwhile, the primers containing urethane dimethacrylate (UDMA) and methyl methacrylate (MMA) (abbreviated as the HC group) showed the highest SBS and lowest reduction (25.51%) after thermocycling. Notably, all the testing groups achieved the ISO10477 standard of 5 MPa. After thermocycling, adhesive failure accounted for the largest proportion of failures in all the groups except the HC group. CONCLUSIONS: The chemical priming treatment can significantly improve the SBS of PEEK and dental cement. Moreover, a primer containing both UDMA and MMA can provide improved bonding for PEEK materials.

CONCLUSIONS L-pyroglutamic acid， syringic acid， bergenin， cinnabar root saponin A， and mycophenolic acid may act as the pharmacodynamic material basis of A. crenata.

Qingxin Zishen Decoction Treats Menopausal Syndrome Due to Yin Deficiency with Effulgent Fire by Regulating KNDy Neurons / 中国实验方剂学杂志

ObjectiveTo explore the comprehensive effects of Qingxin Zishen decoction on the symptom score and neuroendocrine indexes and the mechanism of the decoction in regulating KNDy neurons in the patients with menopausal syndrome. MethodA total of 60 patients with menopausal syndrome due to yin deficiency with effulgent fire who attended the menopausal outpatient of Jiangsu Province Hospital of Chinese Medicine were randomized into an experimental （Qingxin Zishen decoction） group （30 cases） and a control （femoston） group （30 cases）. The treatment lasted for 12 weeks in both groups. The two groups were compared in terms of the comprehensive efficacy， frequency and degree of hot flashes and sweating， modified Kupperman score， and the serum levels of hypothalamic peptide kisspeptin， neurokinin B （NKB）， dynorphin （Dyn）， follicle-stimulating hormone （FSH）， and estradiol （E2）. Result① Comprehensive efficacy： The comprehensive efficacy of the two groups was comparable. ② Frequency and degrees of hot flashes and sweating： After treatment， the frequency and degrees of hot flashes and sweating in the two groups were reduced （P<0.05） and the control group outperformed the experimental group （P<0.05）. ③ Modified Kupperman score and menopausal symptoms： After treatment， the modified Kupperman score decreased in both groups （P<0.05）. After 4 weeks of treatment， the experimental group was superior to the control group in terms of the scores of dizziness and headache （P<0.05）. ④ Serum levels of sex hormones： After treatment， the serum E2 level elevated and the FSH level lowered in both groups （P<0.05）， and the changes were more obvious in the control group （P<0.05）. ⑤ Neuroendocrine indexes： After treatment， the serum levels of kisspeptin and NKB in the two groups decreased （P<0.05）， and the serum Dyn level in the experimental group increased （P<0.05）. Moreover， the experimental group had higher Dyn level than the control group after treatment （P<0.05）. ConclusionQingxin Zishen decoction can alleviate hot flashes， sweating， and other symptoms in the women with menopausal syndrome by acting on the KNDy neurons to lower the kisspeptin and NKB levels and elevate the Dyn level. The findings provide new ideas for the clinical treatment of hot flashes in menopause.

Effectiveness of Integrated Mindfulness-Based Fitness Training Program in Ameliorating Physical Symptoms and Survivor Concerns in Patients With Breast Cancer: A Randomized Clinical Trial.

BACKGROUND: Patients with breast cancer typically experience both mental and physical distress after aggressive treatments. Some studies have explored the use of integrated interventions, such as mindfulness-based or exercise-based approaches, to reduce these symptoms. However, the results of these studies have been conflicting. OBJECTIVE: The aim of this study was to evaluate the effectiveness of an integrated mindfulness-based fitness training (MBFT) program in addressing overactive bladder, fear of cancer recurrence, and female sexual function in patients with breast cancer. METHODS: Fifty patients with breast cancer were either assigned to an 8-week MBFT group or a waitlist control group. The postintervention and preintervention scores were compared using descriptive analysis of the data set, as well as paired and independent t tests. RESULTS: There was no significant improvement in overactive bladder symptoms. Significant differences were observed in survivor concerns for items related to future diagnostic tests (t = 2.667, P = .024; 95% confidence interval [CI], 0.120-1.335), another type of cancer (t = 2.667, P = .024; 95% CI, 0.120-1.335), cancer coming back (t = 4.183, P = .002; 95% CI, 0.297-0.975), dying (t = 2.609, P = .026; 95% CI, 0.093-1.180), and my health (t = 2.887, P = .016; 95% CI, 0.104-0.805). A significant difference was found in the item measuring overall sexual life satisfaction (t = -3.162, P = .013) and sexual desire (MBFT vs waitlist control group, 2.00 vs 1.18; P = .023). CONCLUSION: Mindfulness-based fitness training interventions were effective in enhancing the well-being of patients with breast cancer by reducing fear of recurrence and enhancing sexual function. These findings support the use of MBFT as complementary therapy. IMPLICATIONS FOR PRACTICE: Healthcare providers should carefully assess the individual needs and preferences of each patient and tailor interventions accordingly. In addition, integrating multiple approaches may be more effective in reducing distress.

Visual change as the presenting symptom of a suspected metastatic brain lesion in esophageal cancer: A case report.

INTRODUCTION: Esophageal cancer is the seventh most common malignancy worldwide and the sixth leading cause of cancer mortality with an overall survival rate of <20%. Esophageal cancer frequently metastasizes to distant lymph nodes, lungs, liver, and bones. Cerebral metastases originating from esophageal cancer are rare and often carry a poor prognosis as do most all metastatic lesions in esophageal cancer. CASE PRESENTATION: In this report, we describe a 55-year-old patient with past history of esophageal carcinoma who presented with blurred vision after taking ethambutol for tuberculosis. Ethambutol-induced optic neuropathy was the lead diagnosis. Initial vision testing was normal so additional testing with visual field examination was warranted. The visual field examination revealed homonymous hemianopsia. Subsequent magnetic resonance imaging of his brain, demonstrated a focal lesion, consistent with but not diagnostic of a brain metastasis likely from his primary esophageal malignancy. CONCLUSION: We conclude that a careful review of the medical history and comprehensive assessment are essential in establishing an obscure clinical diagnosis especially in the event that an uncommon metastatic lesion is encountered.

High risk for obstructive sleep apnea and risk of hypertension in military personnel: The CHIEF sleep study.

BACKGROUND: Epidemiological studies have revealed an association between obstructive sleep apnea (OSA) and hypertension in the general population, while the association in military personnel was rarely investigated. AIM: To examine the association between high risk for OSA and hypertension by phenotypes in military young adults. METHODS: A total of 746 military personnel, aged 27.9 years, were included in the cardiorespiratory fitness and health in armed forces (CHIEF)-sleep study in Taiwan in 2020. Antihypertensive medications were not used by the subjects. High risk for OSA was assessed using the Berlin Questionnaire. Hypertension was defined using the 7th Report of the Joint National Committee on Prevention, Detection, Evaluation, and Treatment of High Blood Pressure (JNC 7) and the 2017 American College of Cardiology (ACC)/American Heart Association (AHA) guidelines. The cutoff levels of systolic and diastolic blood pressure (SBP and DBP) for the 2017 ACC/AHA- and JNC 7-based guidelines were 130/140 mmHg and 80/90 mmHg, respectively. Hypertension phenotypes included isolated systolic and diastolic hypertension (ISH, high SBP only and IDH, high DBP only) and combined hypertension (both high SBP and DBP). Multivariable logistic regression analysis with adjustment for demographics, lifestyle and metabolic biomarkers. RESULTS: The prevalence of high risk for OSA, JNC 7-based hypertension and 2017 ACC/AHA-based hypertension were 8.0%, 5.2% and 22.0%, respectively. Those with a high risk for OSA had a higher probability of JNC 7-based overall and combined hypertension (odds ratios (ORs) and 95% confidence intervals: 2.82 (1.07-7.42) and 7.54 (1.10-51.54), although the probabilities of ISH and IDH were unaffected by a high risk for OSA (ORs: 1.96 and 2.35, respectively, both P > 0.05). In contrast, no associations for any hypertension phenotypes were found according to the 2017 ACC/AHA criteria. CONCLUSION: A high risk for OSA was associated with severe hypertension and combined hypertension among Asian military young adults.

Interpeduncular cistern intrathecal targeted drug delivery for intractable postherpetic neuralgia: A case report.

BACKGROUND: Intractable postherpetic neuralgia (PHN) can be difficult to manage even with aggressive multimodal therapies. Patients who experience uncontrolled refractory cranial PHN despite conservative treatment may benefit from an intrathecal drug delivery system (IDDS). For craniofacial neuropathic pain, the traditional approach has been to place the intrathecal catheter tip below the level of the cranial nerve root entry zones, which may lead to insufficient analgesia. CASE SUMMARY: We describe a 69-year-old man with a 1-year history of PHN after developing a vesicular rash in the ophthalmic division of cranial nerve V (trigeminal nerve) distribution. The pain was rated 7-8 at rest and 9-10 at breakthrough pain (BTP) on a numeric rating scale. Despite receiving aggressive multimodal therapies including large doses of oral analgesics (gabapentin 150 mg q12 h, oxycodone 5 mg/acetaminophen 325 mg q6 h, and lidocaine 5% patch 700 mg q12 h) and sphenopalatine ganglion block, there was no relief of pain. Subsequently, the patient elected to have an implantable IDDS with the catheter tip placed at the interpeduncular cistern. The frequency of BTP episodes decreased. The patient's continuous daily dose was adjusted to 0.032 mg/d after 3 mo of follow-up and stopped 5 mo later. He did not report pain or other discomfort at outpatient follow-up 6 mo and 1 year after stopping intracisternal hydromorphone. CONCLUSION: The use of interpeduncular cistern intrathecal infusion with low-dose hydromorphone by IDDS may be effective for severe craniofacial PHN.

In vivo investigation of boron-rich nanodrugs for treating triple-negative breast cancers via boron neutron capture therapy.

Triple-negative breast cancer (TNBC) is characterized by highly proliferative cancer cells and is the only subtype of breast cancer that lacks a targeted therapy. Boron neutron capture therapy (BNCT) is an approach that combines chemotherapy with radiotherapy and can potentially offer beneficial targeted treatment for TNBC patients owing to its unique ability to eradicate cancer cells selectively while minimizing damage to the surrounding healthy cells. Since BNCT relies on specific delivery of a high loading of B10 to the tumor site, there is growing research interest to develop more potent boron-based drugs for BNCT that can overcome the limitations of small-molecule boron compounds. In this study, polyethylene-glycol-coated boron carbon oxynitride nanoparticles (PEG@BCNO) of size 134.2±23.6nm were prepared as a promising drug for BNCT owing to their high boron content and enhanced biocompatibility. The therapeutic efficiency of PEG@BCNO was compared with a state-of-the-art 10BPA boron drug in mice bearing MDA-MB-231 tumor. In the orthotopic mouse model, PEG@BCNO showed higher B10 accumulation in the tumor tissues (6 µg 10B/g tissue compared to 3 µg 10B/g tissue in mice administered B10-enriched 10BPA drug) despite using the naturally occurring 11B/10B boron precursor in the preparation of the BCNO nanoparticles. The in vivo biodistribution of PEG@BCNO in mice bearing MDA-MB-231 showed a tumor/blood ratio of ~3.5, which is comparable to that of the state-of-the-art 10BPA-fructose drug. We further demonstrated that upon neutron irradiation, the mice bearing MDA-MB-231 tumor cells treated with PEG@BCNO and 10BPA showed tumor growth delay times of 9 days and 1 day, respectively, compared to mice in the control group after BNCT. The doubling times (DTs) for mice treated with PEG@BCNO and 10BPA as well as mice in the control group were calculated to be 31.5, 19.8, and 17.7 days, respectively. Immunohistochemical staining for the p53 and caspase-3 antibodies revealed that mice treated with PEG@BCNO showed lower probability of cancer recurrence and greater level of cellular apoptosis than mice treated with 10BPA and mice in the control group. Our study thus demonstrates the potential of pegylated BCNO nanoparticles in effectively inhibiting the growth of TNBC tumors compared to the state-of-the-art boron drug 10BPA.

Pathophysiological Mechanisms Underlying Unilateral Vocal Fold Paralysis in Female Patients: An Ultrasonographic Study.

OBJECTIVES: Laryngeal ultrasonography (LUS) has been suggested as an alternative diagnostic tool for unilateral vocal fold paralysis (UVFP). The present study applied LUS and quantitative laryngeal electromyography (LEMG) in female UVFP patients to investigate the pathophysiologic mechanisms of UVFP. METHODS: In this cross-sectional study, vocal fold (VF) length parameters included resting and phonating VF length measured using B-mode LUS, and color Doppler vibrating length (CDVL) measured using the color Doppler mode. RESULTS: Forty female patients with UVFP were enrolled, among whom 11 and 29 were assigned to the thyroarytenoid (TA) muscle+cricothyroid (CT) muscle group (with CT involvement) and the TA (without CT involvement) group, respectively. In the TA group, the turn frequency in thyroarytenoid-lateral cricoarytenoid (TA-LCA) on the paralyzed side, as observed through LEMG, correlated with the VF length during the resting phase (R=0.368, P=0.050) and CDVL values (R=0.627, P=0.000) on the paralyzed side. In the TA+CT group, the turn ratio in the CT muscle correlated with the normalized phonatory vocal length change (nPLC; R=0.621, P=0.041) on the paralyzed side. CONCLUSION: CDVL and nPLC are two parameters that can be utilized to predict the turn frequencies of TA-LCA in UVFP cases without CT involvement, and the turn ratio of CT in cases of UVFP with CT involvement, respectively. The findings suggest that LUS, as a noninvasive tool, can serve as an alternative method for assessing the severity of laryngeal nerve injury and offer valuable insights into the pathophysiology of UVFP.
