Interictal interleukin-6 and tumor necrosis factor α levels are associated with seizure recurrence in adults with epilepsy.

BACKGROUND: Although there are models predicting epilepsy recurrence under different clinical conditions, few studies have examined blood biomarkers. Inflammation plays a crucial role in the occurrence and development of epilepsy. We analyzed inflammatory mediators in a regional hospital-based epilepsy cohort and investigated their relationship with subsequent epilepsy recurrence. METHODS: Interictal inflammatory mediators were measured in 128 patients diagnosed with epilepsy participating in a prospective study. Inflammatory mediators were compared during the follow-up period between patients who experienced epilepsy recurrence and those who did not. We also assessed the correlation between inflammatory mediators and the time interval until the next recurrence. RESULTS: Over a median 4-month follow-up period, 41 patients experienced seizure recurrence. Differences in interleukin-6 (IL-6) and tumor necrosis factor α (TNF-α) levels were observed between seizure recurrence and non-recurrence groups. After adjusting for covariates through multivariate Cox regression analysis, the patients in the third IL-6 tertile (>2.31 pg/mL; HR: 2.49; 95 % CI: 1.00-6.16; P = 0.049) and in the third TNF-α tertile (>0.74 pg/mL; HR: 2.80; 95 % CI: 1.13-6.92; P = 0.026) had higher risk of seizure recurrence. The time until the next recurrence was negatively correlated with IL-6 level (ρ =  - 0.392, P = 0.011). CONCLUSION: High levels of IL-6 and TNF-α are associated with a higher possibility of seizure recurrence. Future predictive models should also include inflammatory mediators in addition to clinical variables.

Machine learning-based pathomics signature of histology slides as a novel prognostic indicator in primary central nervous system lymphoma.

PURPOSE: To develop and validate a pathomics signature for predicting the outcomes of Primary Central Nervous System Lymphoma (PCNSL). METHODS: In this study, 132 whole-slide images (WSIs) of 114 patients with PCNSL were enrolled. Quantitative features of hematoxylin and eosin (H&E) stained slides were extracted using CellProfiler. A pathomics signature was established and validated. Cox regression analysis, receiver operating characteristic (ROC) curves, Calibration, decision curve analysis (DCA), and net reclassification improvement (NRI) were performed to assess the significance and performance. RESULTS: In total, 802 features were extracted using a fully automated pipeline. Six machine-learning classifiers demonstrated high accuracy in distinguishing malignant neoplasms. The pathomics signature remained a significant factor of overall survival (OS) and progression-free survival (PFS) in the training cohort (OS: HR 7.423, p < 0.001; PFS: HR 2.143, p = 0.022) and independent validation cohort (OS: HR 4.204, p = 0.017; PFS: HR 3.243, p = 0.005). A significantly lower response rate to initial treatment was found in high Path-score group (19/35, 54.29%) as compared to patients in the low Path-score group (16/70, 22.86%; p < 0.001). The DCA and NRI analyses confirmed that the nomogram showed incremental performance compared with existing models. The ROC curve demonstrated a relatively sensitive and specific profile for the nomogram (1-, 2-, and 3-year AUC = 0.862, 0.932, and 0.927, respectively). CONCLUSION: As a novel, non-invasive, and convenient approach, the newly developed pathomics signature is a powerful predictor of OS and PFS in PCNSL and might be a potential predictive indicator for therapeutic response.

Effect of remote ischemic preconditioning on postoperative cognitive dysfunction in adult patients with general anesthesia: a meta-analysis.

BACKGROUND: Remote ischemic preconditioning (RIPC) is proven to have neuroprotective protective effects. Nevertheless, the impact of RIPC on postoperative cognitive dysfunction (POCD) in patients undergoing general anesthesia is controversial. This meta-analysis of randomized controlled trials (RCTs) aimed to assess the effect of RIPC on POCD in adults after general anesthesia. METHODS: Relevant literature was obtained by searching Embase, PubMed, Web of Science, Cochrane Library, Wanfang, and China National Knowledge Infrastructure (CNKI) databases in July 2022. RCTs were included to assess the influences of RIPC on POCD in adults following general anesthesia. Two investigators independently performed literature screening, data extraction, and quality assessment based on the inclusion and exclusion criteria. The incidence of POCD, operation time, and hospital stay were analyzed by Review manager5.4 software. RESULTS: Thirteen RCTs with 1122 participants were selected for this meta-analysis. Compared to the control group, RIPC decreased the incidence of POCD (OR = 0.50, 95% CI 0.31-0.82), as well as reduced the duration of hospitalization (MD = - 0.98, 95% CI - 1.69 to - 0.27), but did not prolong operative time (MD = - 2.65, 95% CI - 7.68 to 2.37). CONCLUSION: RIPC reduced the incidence of POCD in adult patients after general anesthesia and accelerated their discharge.

Lower-grade gliomas surgery guided by GRPR-targeting PET/NIR dual-modality image probe: a prospective and single-arm clinical trial.

Purpose: Lower-grade gliomas (LGGs) are a group of infiltrative growing glial brain tumors characterized by intricate intratumoral heterogeneity and subtle visual appearance differences from non-tumor tissue, which can lead to errors in pathologic tissue sampling. Although 5-ALA fluorescence has been an essential method for visualizing gliomas during surgery, its effectiveness is limited in the case of LGGs due to low sensitivity. Therefore, we developed a novel PET/NIR dual-modality image probe targeting gastrin-releasing peptide receptor (GRPR) in glioma cells to enhance tumor visualization and improve the accuracy of sampling. Methods: A prospective, non-randomized, single-center feasibility clinical trial (NCT03407781) was conducted in the referral center from October 21, 2016, to August 17, 2018. Consecutive enrollment included patients suspected of having LGGs and considered suitable candidates for surgical removal. Group 1 comprised ten patients who underwent preoperative 68Ga-IRDye800CW-BBN PET/MRI assessment followed by intraoperative fluorescence-guided surgery. Group 2 included 42 patients who underwent IRDye800CW-BBN fluorescence-guided surgery. The primary endpoints were the predictive value of preoperative PET imaging for intraoperative fluorescence and the sensitivity and specificity of fluorescence-guided sampling. Results: Thirty-nine patients were included in the in-depth analysis of endpoints, with 25 (64.1%) exhibiting visible fluorescence, while 14 (35.9%) did not. The preoperative positive PET uptake exhibited a greater accuracy in predicting intraoperative fluorescence compared to MRI enhancement (100% [10/10] vs. 87.2% [34/39]). A total of 125 samples were harvested during surgery. Compared with pathology, subjective fluorescence intensity showed a sensitivity of 88.6% and a specificity of 88.2% in identifying WHO grade III samples. For WHO grade II samples, the sensitivity and specificity of fluorescence were 54.7% and 88.2%, respectively. Conclusion: This study has demonstrated the feasibility of the novel dual-modality imaging technique for integrated pre- and intraoperative targeted imaging via the same molecular receptor in surgeries for LGGs. The PET/NIR dual-modality probe exhibits promise for preoperative surgical planning in fluorescence-guided surgery and provides greater accuracy in guiding tumor sampling compared to 5-ALA in patients with LGGs.

Ventricular tachycardia and acute heart failure induced by atropine in the treatment of bradycardia: A case report and literature review.

RATIONALE: Despite various advantages of laparoscopic surgical procedures, artificial pneumoperitoneum might lead to hemodynamic fluctuations including severe bradycardia and cardiac arrest. Atropine is usually proposed to treat intraoperative severe bradycardia ( < 40 beats per minute). However, atropine could induce ventricular arrhythmias, which might be life-threatening in severe case. PATIENT CONCERNS: Here, we reported a 41-year-old female who was diagnosed with gallbladder polyps and was scheduled for laparoscopic cholecystectomy under general anesthesia. DIAGNOSES: Bradycardia occurred suddenly during the operation and atropine was injected intravenously. Eventually the patient developed ventricular tachycardia and acute heart failure. INTERVENTIONS: We organized an urgent consultation and the patient was treated immediately. OUTCOMES: Fortunately, the patient experienced no complications after timely diagnosis and treatment. After 6 months of follow-up, her New York Heart Association classification was I with no complications. LESSONS: This case highlighted that the administration of atropine to treat bradycardia may lead to ventricular tachycardia and acute heart failure, and anesthesiologists should remain vigilant to avoid potentially life-threatening consequences.

Soft and stretchable organic bioelectronics for continuous intraoperative neurophysiological monitoring during microsurgery.

In microneurosurgery, it is crucial to maintain the structural and functional integrity of the nerve through continuous intraoperative identification of neural anatomy. To this end, here we report the development of a translatable system leveraging soft and stretchable organic-electronic materials for continuous intraoperative neurophysiological monitoring. The system uses conducting polymer electrodes with low impedance and low modulus to record near-field action potentials continuously during microsurgeries, offers higher signal-to-noise ratios and reduced invasiveness when compared with handheld clinical probes for intraoperative neurophysiological monitoring and can be multiplexed, allowing for the precise localization of the target nerve in the absence of anatomical landmarks. Compared with commercial metal electrodes, the neurophysiological monitoring system allowed for enhanced post-operative prognoses after tumour-resection surgeries in rats. Continuous recording of near-field action potentials during microsurgeries may allow for the precise identification of neural anatomy through the entire procedure.

Associated factors for postoperative delirium following major abdominal surgery: A systematic review and meta-analysis.

OBJECTIVES: Postoperative delirium (POD) is a common postsurgical complication. The early identification of its risk factors is the first step toward reducing POD. The predictive factors for POD in patients after major abdominal surgery remain obscure. Therefore, this meta-analysis aimed to comprehensively summarize the risk factors of POD after major abdominal surgery. METHODS: POD studies published between January, 1900 and June 2022 were obtained by searching PubMed, Cochrane Library, Web of Science, Embase, and Medline. Two authors independently reviewed the studies to extract the risk factors and assessed the quality of related articles using the Newcastle-Ottawa Scale. Data were recorded, and a meta-analysis was performed using Review Manager version 5.4.1. RESULTS: Ten studies including total 2900 patients undergoing major abdominal surgery, were eligible for analysis, 608 of whom developed POD, for a cumulative incidence of 21%. This pooled analysis suggested the statistically significant risk factors for POD were age, higher American Society of Anesthesiologists grade, lower preoperative Mini-Mental State Examination score, cognitive impairment, preoperative Katz-ADL score <6, preoperative and postoperative hypoalbuminemia, lower preoperative insulin-like growth factor-1 levels, and longer duration of anesthesia. CONCLUSION: POD is common in patients undergoing major abdominal surgery. This meta-analysis identified risk factors that may aid the early detection of POD and play a prominent role in preventing POD.

Risk factors of delirium after gastrointestinal surgery: A meta-analysis.

BACKGROUND: Postoperative delirium is one of the common complications after any major surgery such as gastrointestinal surgery. And it is related to increased mortality and morbidity and other serious surgical outcomes. AIMS: This study aims to identify risk factors for postoperative delirium in patients undergoing gastrointestinal surgery. MATERIALS AND METHODS: Relevant studies published before August 2021 were searched on Pubmed, Embase and Medline. The risk of bias of included studies was assessed by Newcastle-Ottawa Scale (NOS). A random-effects model of DerSimonian-Laird was used to synthesise the overall ORs or RRs for all risk factors. MOOSE checklist was used to review this manuscript. RESULTS: A total of 21 studies including 6165 patients were finally included for quantitative analysis. The pooled incidence of postoperative delirium is 11% (95% CI: 9%-15%). 16 risk factors were identified, in which age, sex, alcohol consumption, cerebrovascular diseases, cardiovascular diseases, use of sleeping pills, history of delirium, preoperative C-reactive protein (CRP) levels, operation time, blood loss and perioperative blood transfusion were statistically significant while smoking, American Society of Anesthesiologists (ASA) score, performance status, diabetes and operation approach were insignificant. DISCUSSION: This meta-analysis may provide tips for nursing staff and surgeons to design and implement prevention programmes to reduce the incidence of postoperative delirium. CONCLUSION: Potential risk factors of delirium after gastrointestinal surgery are age, sex, alcohol consumption, cerebrovascular diseases, cardiovascular diseases, use of sleeping pills, history of delirium, preoperative CRP levels, operation time, blood loss and blood transfusion.

Hypertrophic pulmonary osteoarthropathy with esophageal sarcomatoid carcinoma: a case report.

Hypertrophic pulmonary osteoarthropathy (HPOA), mainly manifested clubbing, is rare in patients with esophageal sarcomatoid carcinoma. We herein describe a 48-year-old Chinese man whose advanced sarcomatoid carcinoma was diagnosed while examining his symptoms of HPOA. The patient had no opportunity of surgery after surgical evaluation. Chemoradiation, including 5 cycles of chemotherapy (Paclitaxel liposome 60 mg day 1 and nedaplatin 30 mg day 1, q1w) and 6MV-X/VMAT-95%PGTV 59.92 Gy/2.14 Gy/28 F and 95%PTV 50.4 Gy/1.8 Gy/28 F, and subsequent 6 cycles of chemotherapy (paclitaxel liposome 210 mg day 1 and nedaplatin 50 mg day 1, 60 mg day 2, q3w) shrank the tumor and the condition of the patient became stable without clubbing remission or exacerbation. No medical case report found in a PubMed search in the indexed English-language literature in the past 20 years, though there are some reports of HPOA combined with other pathologic types of esophageal carcinoma. The patient's condition was effectively controlled by chemotherapy and radiotherapy and showed stable disease. However, the five-year survival rate of advanced esophageal carcinoma patients is very low with low life quality, and the adverse reactions also contribute to low life quality. The purpose of this report is to present the feature and our treatment for primary esophageal sarcomatoid carcinoma with HPOA, which could be helpful for further understanding of the disease and clinical decision making. Moreover, this article also reviews esophageal carcinoma with HPOA and sarcomatoid carcinoma in the esophagus. We look forward to the breakthrough of immunotherapy and molecular targeting therapy to improve the situation.

The prognostic value of a Methylome-based Malignancy Density Scoring System to predict recurrence risk in early-stage Lung Adenocarcinoma.

Current NCCN guidelines do not recommend the use of adjuvant chemotherapy for stage IA lung adenocarcinoma patients with R0 surgery. However, 25% to 40% of patients with stage IA disease experience recurrence. Stratifying patients according to the recurrence risk may tailor adjuvant therapy and surveillance imaging for those with a higher risk. However, prognostic markers are often identified by comparing high-risk and low-risk cases which might introduce bias due to the widespread interpatient heterogeneity. Here, we developed a scoring system quantifying the degree of field cancerization in adjacent normal tissues and revealed its association with disease-free survival (DFS). Methods: We recruited a cohort of 44 patients with resected stage IA lung adenocarcinoma who did not receive adjuvant therapy. Both tumor and adjacent normal tissues were obtained from each patient and subjected to capture-based targeted genomic and epigenomic profiling. A novel methylome-based scoring system namely malignancy density ratio (MD ratio) was developed based on 39 patients by comparing tumor and corresponding adjacent normal tissues of each patient. A MD score was then obtained by Wald statistics. The correlations of MD ratio, MD score, and genomic features with clinical outcome were investigated. Results: Patients with a high-risk MD ratio showed a significantly shorter postsurgical DFS compared with those with a low-risk MD ratio (HR=4.47, P=0.01). The MD ratio was not associated with T stage (P=1), tumor cell fraction (P=0.748) nor inflammatory status (p=0.548). Patients with a high-risk MD score also demonstrated an inferior DFS (HR=4.69, P=0.039). In addition, multivariate analysis revealed EGFR 19 del (HR=5.39, P=0.012) and MD score (HR= 7.90, P=0.01) were independent prognostic markers. Conclusion: The novel methylome-based scoring system, developed by comparing the signatures between tumor and corresponding adjacent normal tissues of individual patients, largely minimizes the bias of interpatient heterogeneity and reveals a robust prognostic value in patients with resected lung adenocarcinoma.

Comparison of the performance of two depression rating scales in patients with epilepsy in southern China.

OBJECTIVE: The aim of this study was to evaluate and compare the performance of the Chinese version of the Neurological Disorder Depression Inventory for Epilepsy (CNDDI-E) with that of the depression subscale of the Hospital Anxiety and Depression Scale (C-HADS-D) as screening tools for depression in the same patients with epilepsy (PWE). METHODS: A total of 213 consecutive PWE were evaluated. Receiver operating characteristic (ROC) analysis was performed using the C-NDDI-E and C-HADS-D as predictors and the Chinese version of the Mini International Neuropsychiatric Interview (C-MINI) as the gold standard. RESULTS: The area under the curve (AUC) for the C-NDDI-E was 0.870, and the optimal cutoff score was >11 (sensitivity 85.71%, specificity 79.78%); for the C-HADS-D, the AUC was 0.804, and the optimal cutoff score was >5 (sensitivity 85.71%, specificity 62.36%). The AUC for the C-NDDI-E was larger than the AUC for the C-HADS-D, but the comparison of the AUCs revealed no significant differences (P = 0.1444). CONCLUSION: Our findings indicate that the C-NDDI-E and C-HADS-D have high validity and support the use of these screening tools for depression in PWE. Moreover, the C-NDDI-E is a better screening scale for diagnosing depression than the C-HADS-D according to the results of this study.

Validation of the Chinese version of the Scale for Suicide Ideation-Worst in adult patients with epilepsy.

OBJECTIVE: The aim of this study was to validate the Chinese version of the Scale for Suicide Ideation-Worst (SSI-W) for screening suicide ideation in Chinese adult patients with epilepsy (PWE). METHOD: A consecutive sample of Chinese adult PWE from a tertiary hospital completed the SSI-W and the suicidality module of the Chinese version of the Mini International Neuropsychiatric Interview (MINI) Plus 5.0.0. RESULTS: A total of 269 PWE completed the scales. According to the MINI, 59 patients (21.9%) had suicidal ideation. The Cronbach's α coefficient for the SSI-W was 0.96. Receiver operating characteristic (ROC) curve analysis showed that the area under the curve (AUC) for the SSI-W was 0.957 (95% confidence interval [CI] = 0.935-0.980). With a cutoff score of 2 points, the SSI-W demonstrated the best psychometric properties: a sensitivity of 95.8%, a specificity of 87.3%, a positive predictive value (PPV) of 56.7%, and a negative predictive value (NPV) of 99.0%. The scores for items 11 (Reason for attempt) and 18 (Final acts) were not significantly different (p > 0.05) in patients with suicidal ideation, while the scores for the other items were significantly different between these groups of patients. CONCLUSION: The Chinese version of the SSI-W proved to be a reliable and effective assessment tool for screening suicidal ideation in Chinese adult PWE.

Validation of the Chinese version of the Hamilton Rating Scale for Depression in adults with epilepsy.

OBJECTIVE: This study aimed to validate the Chinese version of the 17-item Hamilton Rating Scale for Depression (C-HRSD-17) for use in adult patients with epilepsy (PWE). METHODS: A consecutive sample of Chinese adult PWE from a tertiary hospital was examined using the C-HRSD-17 and the Mini International Neuropsychiatric Interview (MINI) Plus Chinese Version 5.0.0. RESULTS: A total of 191 PWE completed the assessment of depression. According to the MINI, thirty patients (15.7%) had current major depressive disorder (MDD). The Cronbach's α coefficient for the C-HRSD-17 was 0.832. Receiver operating characteristic (ROC) analysis showed an area under the curve (AUC) of 0.983 (95% CI = 0.968-0.998). With a cutoff score of 9, the C-HRSD-17 demonstrated the best psychometric properties, with a sensitivity of 96.7%, a specificity of 93.8%, a positive predictive value (PPV) of 74.4%, and a negative predictive value (NPV) of 99.3%. CONCLUSION: The C-HRSD-17 proved to be a valid and reliable assessment tool, with a cutoff score of 9 for screening of current MDD in Chinese adult PWE.

Involvement of MaSom1, a downstream transcriptional factor of cAMP/PKA pathway, in conidial yield, stress tolerances, and virulence in Metarhizium acridum.

Flo8/Som1, which functions downstream from the cyclic AMP (cAMP)-dependent protein kinase A (PKA) pathway, plays important roles in hyphal development, spore formation, and virulence in yeast and several filamentous fungi. However, the functions of Som1 in entomopathogenic fungi are still a mystery. In this study, MaSom1, a Flo8/Som1 homolog, was identified and functionally characterized in a model entomopathogenic fungus Metarhizium acridum. Similar to Flo8/Som1 in other fungi, MaSom1 mainly localized to the nucleus in M. acridum. Disruption of MaSom1 reduced conidial yield, delayed conidial germination, and impaired the fungal tolerances to heat and UV-B. The expression levels of some genes involved in defenses of heat shock and UV-B radiation were significantly reduced in ΔMaSom1. MaSom1 is also important for cell wall integrity and conidial surface structures in M. acridum. Some genes related to fungal cell wall synthesis were downregulated in ΔMaSom1. Bioassays showed that ΔMaSom1 had a dramatically decreased virulence after both topical inoculation and intrahemocoel injection of the fungus in locusts. Moreover, inactivation of MaSom1 reduced appressorium formation, diminished fungal growth in locust hemolymph in vitro, and enhanced insect immune responses. Taken together, these results indicate that disruption of MaSom1 leads to a decline of fungal virulence because of impairments in conidial germination and appressorium formation, reduction of fungal growth in host hemolymph, and enhancement of insect immune responses owing to the changes in conidial surface structures.

The results showed that medication characteristics of professor Li Dian-gui in treating CAGIM included drug combination of aromatic medicine bitter-cold herbs, preferring to activating to invigorate the spleen and good at using the qi-regulating drugs. It demonstrated that we can adopt the therapy of Huazhuo Jiedu and Xingpi Xingqi therapies in treating CAGIM in addition to the traditional approach of nourishing Yin and activating blood circulation, opening up a novel approach for TCM in healing the pathema.

[Effect of huazhuo jiedu recipe on gastric juice compositions and tumor markers in patients with chronic atrophic gastritic precancerosis].

OBJECTIVE: To observe clinical efficacy of Huazhuo Jiedu Recipe (HJR) on chronic atrophic gastritic precancerosis (CAGP), and its effect on contents of lactic acid, total acid, free acid, and nitrite in the gastric juice, as well as tumor markers in gastric juice and blood. METHODS: Two hundred and twenty-nine patients with CAGP were randomly assigned to two groups, the 119 patients in the treated group orally took HJR and the 110 patients in the control group orally took Weifuchun Tablet. The therapeutic course for all was three months, two courses in total. The therapeutic efficacy, changes of gastric acid contents before and after treatment were observed, and the tumor markers in the gastric juice and blood were detected using electrochemical luminescence immunoassay. RESULTS: The pathological effective rate was 83.2% (99/119) in the treated group and 60.9% (67/110) in the control group, showing significant difference between the two groups (P <0.05). The total acids and free acids in the gastric juice were significantly improved, contents of lactic acid and nitrite were significantly lowered in the two groups. Both contents of carcinoembryonic antigen (CEA), carbohydrate antigen19-9 (CA19-9), carbohydrate antigen72-4 (CA72-4), and carbohydrate antigen125 (CA125) in the gastric juice and serum were significantly lowered after treatment in the treated group (P<0.05). Compared with the normal control group, the therapeutic effect was more obvious in the treated group (P<0.05). CONCLUSIONS: HJR could stimulate the gastric membranous secretion, enhance contents of total acids and free acids. It could prevent the further progress of CAGP by decreasing contents of lactic acid and nitrite in the gastric juice, and lowering contents of CEA, CA19-9, CA72-4, and CA125 in the gastric juice and serum.
