RESUMEN
PURPOSE: Chronic obstructive pulmonary disease (COPD) is a major public health concern. Exacerbation of COPD leads to poor health and frequent episodes of increased systemic and airway inflammation. Immunomodulatory drugs have garnered extensive attention because they may reduce the rate of COPD exacerbation. This review aimed to evaluate the efficacy and safety of nemiralisib in COPD patients. METHODS: Medical databases, including the Cochrane Library, EMBASE, and PubMed, were queried from inception to June 2023 to identify randomized controlled trials (RCTs) on the efficacy of nemiralisib in COPD patients. This systematic review was performed according to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines. The Cochrane Collaboration tool was used to assess the risk of bias of the included RCTs. Two authors independently conducted literature screening and data extraction. Key information from the included studies was extracted, tabulated, and compared using a data extraction table. Moreover, the key characteristics, quality, potential bias, and endpoint outcomes of the included studies were summarized. A meta-analysis was conducted when the study outcomes were sufficiently comparable, and the required data were available for extraction. FINDINGS: Initially, 48 references were identified, leading to the inclusion of four trials. No significant difference was found between the nemiralisib and placebo groups in St George's Respiratory Questionnaire score, modified Medical Research Council Dyspnea Scale score, COPD Assessment Test score, time to next on-treatment exacerbation, proportion of patients achieving exacerbation recovery, time to exacerbation recovery, and rescue medication use. Contrastingly, the results demonstrated that nemiralisib may lower oral corticosteroid use during acute exacerbation of COPD. Meanwhile, the efficacy of nemiralisib on the exacerbation rate, as well as several parameters associated with lung function, including forced expiratory volume in 1 second, specific airway conductance, specific imaging airway wall thickness, distal specific imaging airway volume measured at functional residual capacity, specific imaging airway resistance, low attenuation score, and internal airflow lobar distribution in the lower pulmonary region, were conflicting. Attributed to the limited number of included RCTs and insufficient extracted data, it was not feasible to conduct a comprehensive meta-analysis. IMPLICATIONS: Because of insufficient data, this systematic review could not make any definitive statement regarding the efficacy of nemiralisib in COPD patients. In terms of safety, nemiralisib was generally well tolerated. Further trials are required to explore the efficacy of this drug.

Ischemic stroke is a common type of stroke that significantly affects human well-being and quality of life. In order to further characterize the pathophysiology of ischemic stroke and develop new treatment strategies, ischemic stroke models with controllable and consistent response to potential clinical treatments are urgently needed. The middle cerebral artery occlusion (MCAO) model is currently the most widely used animal model of ischemic stroke. This review discusses various methods for constructing the MCAO model and compares their advantages and disadvantages in order to provide better approaches for studying ischemic stroke.
RESUMEN
Objective: We aimed to investigate the relationship between systemic inflammatory response index (SIRI) and functional outcome after aneurysmal subarachnoid hemorrhage (aSAH). Methods: A retrospective cohort study was performed involving all consecutive aSAH patients admitted to our institution. The modified Rankin Scale (mRS) score was performed to determine the functional outcomes of all patients at 3 months after aSAH. Results were categorized as favorable (mRS score 0-2) and unfavorable (mRS score 3-6). Univariate and multivariate logistic regressive analyses were utilized to identify the prognostic significance of SIRI. To minimize the effects of confounding factors, patients were stratified according to the optimal cut-off value of SIRI with propensity score matching (PSM). Further subgroup analysis was conducted to verify the consistency of our findings and Pearson's correlation analysis was used to assess the relationship between SIRI and the severity of aSAH. Results: In this study, 350 patients were enrolled and 126 (36.0%) of them suffered unfavorable outcomes. The SIRI of 5.36 × 109/L was identified as the optimal cut-off value. Two score-matched cohorts (n = 100 in each group) obtained from PSM with low SIRI and high SIRI were used for analysis. A significantly higher unfavorable functional outcome rate was observed in patients with high SIRI before and after PSM (p < 0.001 and 0.017, respectively). Multivariate logistic regression analysis demonstrated that SIRI value ≥ 5.36 × 109/L was an independent risk factor for poor outcomes (OR 3.05 95% CI 1.37-6.78, p = 0.006) after adjusting for possible confounders. A identical result was discovered in the PSM cohort. In ROC analysis, the area under the curve (AUC) of SIRI was 0.774 which shown a better predictive value than other inflammatory markers observed in previous similar studies. Pearson's correlation analysis proved the positive association between SIRI and aSAH severity. Conclusions: Elevated SIRI at admission is associated with worse clinical status and poorer functional outcomes among patients with aSAH. SIRI is a useful inflammatory marker with prognostic value for functional outcomes after aSAH.
RESUMEN
(1) Background: To explore the correlation between the blood urea nitrogen to creatinine ratio (UCR) and in-hospital mortality in non-traumatic subarachnoid hemorrhage patients. (2) Methods: Specific clinical information was collected from the Medical Information Mart for Intensive â £ (MIMIC-â £) database. The optimal cut-off value of the UCR was calculated with ROC curve analysis conducted using the maximum Youden index for the prediction of survival status. Univariable and multivariable logistic regression analyses were also carried out to assess the prognostic significance of UCR, and the Kaplan−Meier (K−M) analysis was conducted to draw the survival curves. Then, the 1:1 propensity score matching (PSM) method was applied to improve the reliability of the research results while balancing the unintended influence of underlying confounders. (3) Results: This retrospective cohort study included 961 patients. The optimal cut-off value of the UCR for in-hospital mortality was 27.208. The PSM was performed to identify 92 pairs of score-matched patients, with balanced differences exhibited for nearly all variables. According to the K−M analysis, those patients with a UCR of more than 27.208 showed a significantly higher level of in-hospital mortality compared to the patients with a UCR of less than 27.208 (p < 0.05). After the adjustment for possible confounders, those patients whose UCR was more than 27.208 still had a significantly higher level of in-hospital mortality than the patients whose UCR was less than 27.208, as revealed by the multivariable logistic regression analysis (OR = 3.783, 95% CI: 1.959~7.305, p < 0.001). Similarly, the in-hospital mortality remained substantially higher for those patients in the higher UCR group than for the patients in the lower UCR group after PSM. (4) Conclusion: A higher level of the UCR was evidently associated with an increased risk of in-hospital mortality, which made the ratio useful as a prognostic predictor of clinical outcomes for those patients with non-traumatic subarachnoid hemorrhage.
RESUMEN
(1) Objective: To reveal the correlation between the hemoglobin-to-red cell distribution width ratio (HRR) and all-cause mortality (ACM) among the septic patients with atrial fibrillation. (2) Methods: Specific clinical information was collected from the Medical Information Mart for Intensive IV (MIMIC-IV) database. The optimal cut-off value of HRR was calculated through ROC curve analysis conducted by using the maximum Youden index for the prediction of survival status. In addition, univariable and multivariable Cox regressive analyses were carried out to assess the prognostic significance of HRR and the Kaplan-Meier (K-M) analysis was conducted to draw the survival curves. Then, the 1:1 propensity score matching (PSM) method was adopted to improve the reliability of research result while balancing the unintended influence of underlying confounders. (3) Results: There were 9228 patients participating in this retrospective cohort study. The optimal cut-off value of the HRR was determined as 5.877 for in-hospital mortality. The PSM was performed to identify 2931 pairs of score-matched patients, with balanced differences exhibited by nearly all variables. According to the K-M analysis, those patients with a lower HRR than 5.877 showed a significantly higher level of in-hospital mortality, 28-day mortality, and 90-day mortality, compared to the patients with HRR ≥ 5.877 (p < 0.001). After the adjustment of possible confounders, those patients whose HRR was below 5.877 had a significantly higher level of in-hospital mortality than the patients with HRR ≥ 5.877, as revealed by the multivariable Cox regression analysis (HR = 1.142, 95%CI: 1.210−1.648, p < 0.001). Similarly, the ACM remained substantially higher in those patients with a lower HRR than in the patients with higher HRR after PSM. (4) Conclusion: A lower HRR (<5.877) was evidently associated with an increased risk of ACM, which made it applicable as a prognostic predictor of clinical outcomes for those septic patients with atrial fibrillation.
RESUMEN
PURPOSE: A molecular pathological grading method was tested in WHO grade 2 meningiomas to judge whether this molecular grading can more accurately evaluate meningioma biological behaviour. METHODS: The medical records and paraffin-embedded tissues of surgically resected WHO grade 2 meningioma patients in our department from January 1, 2010, to December 31, 2020, were collected. The molecular pathological risk grading suggested by Sahm et al. was adopted and the patients were graded as low, intermediate and high risk. Progression-free survival (PFS), malignant progression-free survival (MPFS) and overall survival (OS) were analysed. Univariate and multivariate analysis were performed to determine the relationship between molecular risk grading and patient survival. RESULTS: Of the 98 patients, 13 (13.2%) were graded as low risk, 63 patients (64.3%) were graded as intermediate risk, and 22 patients (22.4%) were graded as high risk. With increasing molecular risk grade, the rates of tumour recurrence, malignant progression and mortality increased significantly (P < 0.05). Multivariate analysis showed that molecular risk grading was negatively associated with PFS (HR 0.018, 95% CI 0.003-0.092), MPFS (HR 0.040, 95% CI 0.006-0.266) and OS (HR 0.088, 95% CI 0.016-0.472) (P < 0.01), and gross total resection (Simpson grade I-III) significantly prolonged PFS (HR 5.882, 95% CI 2.538-13.699) and OS (HR 2.611, 95% CI 1.117-7.299) (P < 0.05). CONCLUSION: Sahm et al.'s molecular risk grading can further refine the classification of WHO grade 2 meningiomas and more accurately evaluate their biological behaviour and patient prognosis.

Objective: We aim at investigating the molecular mechanisms through which the Qingfei Jiedu decoction (QFJDD) regulates PD-L1 expression in lung adenocarcinoma (LUAD). Methods: Bioactive compounds and targets of QFJDD were screened from TCMSP, BATMAN-TCM, and literature. Then, GeneCard, OMIM, PharmGKB, Therapeutic Target, and DrugBank databases were used to identify LUAD-related genes. The protein-protein interaction (PPI) network was constructed using overlapping targets of bioactive compounds in LUAD with the Cytoscape software and STRING database. The potential functions and pathways in which the hub genes were enriched by GO, KEGG, and DAVID pathway analyses. Molecular docking of bioactive compounds and key genes was executed via AutoDock Vina. Qualitative and quantitative analyses of QFJDD were performed using UPLC-Q-TOF-MS and UPLC. Expressions of key genes were determined by qRT-PCR, immunoreactivity score (IRS) of PD-L1 was assessed by immunohistochemistry (IHC), while the CD8+PD-1+T% derived from spleen tissues of Lewis lung cancer (LLC) bearing-mice was calculated using flow cytometry (FCM). Results: A total of 53 bioactive compounds and 288 targets of QFJDD as well as 8151 LUAD associated genes were obtained. Further, six bioactive compounds, including quercetin, luteolin, kaempferol, wogonin, baicalein, and acacetin, and 22 hub genes were identified. The GO analysis showed that the hub genes were mainly enriched in DNA or RNA transcription. KEGG and DAVID pathway analyses revealed that 20 hub genes were primarily enriched in virus, cancer, immune, endocrine, and cardiovascular pathways. The EGFR, JUN, RELA, HIF1A, NFKBIA, AKT1, MAPK1, and MAPK14 hub genes were identified as key genes in PD-L1 expression and PD-1 checkpoint pathway. Moreover, ideal affinity and regions were identified between core compounds and key genes. Notably, QFJDD downregulated EGFR, JUN, RELA, HIF1A, NFKBIA, and CD274 expressions (p < 0.05), while it upregulated AKT1 and MAPK1 (p < 0.05) levels in A549 cells. The PD-L1 IRS of LLC tissue in the QFJDD high dose (Hd) group was lower than model group (p < 0.01). CD8+PD-1+T% was higher in the QFJDD Hd group than in normal and model groups (p < 0.05). Conclusion: QFJDD downregulates PD-L1 expression and increases CD8+PD-1+T% via regulating HIF-1, EGFR, JUN and NFκB signaling pathways. Therefore, QFJDD is a potential treatment option for LUAD.
RESUMEN
Objective: To explore the relationship between fibrinogen and neutrophil to lymphocyte ratio (F-NLR) score and functional outcomes after aneurysmal subarachnoid hemorrhage (aSAH). Method: A retrospective study was conducted that involved all consecutive patients with aSAH admitted to our institution from March 2018 to October 2021. Factors, such as demographics, comorbidities, clinical characteristics, neuroradiological data, and laboratory parameters, were collected from institutional databases. All patients achieved neurological assessment using the modified Rankin Scale (mRS) score 3 months after discharge to clarify the functional outcomes. The results were classified as favorable (mRS score 0-2) and unfavorable (mRS score 3-6). Univariate and multivariable analyses were performed to identify the relevant factors between inflammatory markers and functional outcomes after aSAH. Subsequently, a receiver operating characteristic (ROC) curve analysis was conducted to evaluate the predicting performance of variables. A propensity score match (PSM) was performed to correct imbalances in patients' baseline characteristics. Results: Finally, 256 patients with aSAH were included in the study cohort. A total of 94 (36.7%) patients had an unfavorable outcome. F-NLR scores were 0 [interquartile range (IQR) 0-1] and 1 (IQR 1-2) in patients with favorable and unfavorable outcomes, respectively (p < 0.001). After adjustment, the F-NLR score on admission remained significantly associated with unfavorable outcomes in patients with aSAH. In the multivariable analysis, the F-NLR score was regarded as an independent risk factor of unfavorable outcomes [odds ratio (OR) 3.113, 95% CI 1.755-5.523, p < 0.001]. In ROC analysis, the optimal cutoff value of the F-NLR score was 0.5 points. Two cohorts (n = 86 in each group) obtained from PSM with low F-NLR scores (0 points) and high F-NLR scores (1-2 points) were used for analysis. A significantly higher unfavorable functional outcome rate was observed in patients with high F-NLR scores (33.7 vs. 9.3%, p < 0.001). The area under the curve (AUC) values of F-NLR scores before and after PSM were 0.767 and 0.712, respectively. Conclusion: Fibrinogen and neutrophil to lymphocyte ratio score was an independent risk parameter associated with unfavorable functional outcomes at 3 months after aSAH. A higher F-NLR score predicts the occurrence of poor functional outcomes.
RESUMEN
Objective: The aim of this study was to explore the correlation between the mean of 24-h venous blood glucose (BG) and in-hospital mortality and all-cause mortality (ACM) in patients with subarachnoid hemorrhage (SAH). Methods: Detailed clinical information was acquired from the Medical Information Mart for Intensive IV (MIMIC-IV) database. The best cutoff value of mean BG was calculated using the X-tile program. Univariate and multivariate logistic regressive analyses were utilized to analyze the prognosis significance of mean BG, and survival curves were drawn using the Kaplan-Meier (K-M) approach. To improve the reliability of results and balance the impact of underlying confounders, the 1:1 propensity score matching (PSM) approach was utilized. Results: An overall of 1,230 subjects were selected herein. The optimal cutoff value of the mean BG for in-hospital mortality was 152.25. In addition, 367 pairs of score-matched subjects were acquired after PSM analysis, and nearly all variables' differences were balanced. K-M analysis showed that patients with mean BG ≥ 152.25 mg/dl had significantly higher in-hospital, 3-month, and 6-month mortalities compared with patients with mean BG < 152.25 mg/dl (p < 0.001). The multivariable logistic regressive analyses revealed that patients with mean BG ≥ 152.25 mg/dl had significantly increased in-hospital mortality compared with patients with mean BG < 152.25 mg/dl after the adjustment for possible confounders (OR = 1.994, 95% CI: 1.321-3.012, p = 0.001). Similar outcomes were discovered in the PSM cohort. Conclusion: Our data suggested that mean BG was related to ACM of patients with SAH. More studies are needed to further analyze the role of the mean of 24-h venous BG in patients with SAH.
RESUMEN
Slightly acidic electrolyzed water (SAEW) is often used on eggs to remove microorganisms, but the cuticle will be damaged, causing bacterial invasion and deterioration of egg quality during preservation. Therefore, a combination of SAEW disinfection with chitosan (CS) and pectin (PT) composite coating (CS + PT) was tried in preventing bacterial invasion and prolonging the shelf life of eggs. The results showed the order of decontamination effectiveness on contaminated eggs was SAEW > Electrolyzed reduced water (ERW) + SAEW > ERW > deionized water. The CS + PT coating used on SAEW-disinfected eggs inhibits the S. enteritidis invasion (reduced by 63.3%) and was successfully used to maintain the quality of eggs (Haugh unit 48.63, Weight loss 7.34%, Yolk index 0.29, pH 8.93) after 8 weeks storage at 25 â. The results revealed that the combination of SAEW and CS + PT was a very promising method for egg preservation.

OBJECTIVE: To explore prognostic factors of complete recovery of oculomotor nerve palsy (ONP) induced by posterior communicating artery aneurysm (PcomAA). METHOD: PcomAA patients aged 18-60 years combined with ONP who underwent surgical clipping or endovascular embolization at our institution between January 2014 and January 2020 were enrolled. Characteristics included maximum diameter of aneurysm, width of aneurysm, subarachnoid hemorrhage (SAH), duration of ONP, age, sex, ONP type, treatment method were compared. Based on the recovery of ONP, patients were separated into two groups: complete recovery group, partial and no recovery group. Analyzing by univariate and multivariate logistic regressions to identify the independent prognostics for complete ONP recovery. We established a score based on these prognostics. Receiver operating characteristics (ROC) were conducted to under the performance of the predictors and score. RESULTS: Finally, ONP type (OR 6.457 95% CI 1.664-25.052, p = 0.007), treatment method (OR 5.051, 95% CI 1.332-19.158, p = 0.017), and interval to treatment ≤2 weeks (OR 25.601 95% CI 6.222-105.340, p < 0.001) were independent predictors of complete ONP recovery. The score had an area under the curve (AUC) value of 0.870. We defined that the score higher than 5 points as easier to achieve complete ONP recovery, and the AUC value of this definition was 0.821. CONCLUSIONS: For ONP induced by PcomAA in patients aged 18-60 years, the best prognostic factor for complete ONP recovery was timely treatment. The ONP type and treatment methods were correlated with complete ONP recovery.

BACKGROUND: Exercise intolerance was prevalent in people with chronic obstructive pulmonary disease (COPD) and had a detrimental effect on the quality of life. We aimed to evaluate the efficacy and safety of nitrate supplementation in exercise tolerance of people with COPD. METHODS: We searched medical databases including Cochrane Library, EMBASE, and PubMed from inception to October 2020 for randomized control trials in treating COPD with nitrate supplementation. RESULTS: Nine trials were identified. Compared with placebo, nitrate supplementation has no significant effect on the following variables: exercise endurance time (standard mean difference [SMD]: 0.06; 95% confidence interval [CI]: -0.39 to 0.52; Pâ=â.79), exercise capacity (SMD: 0.30; 95% CI: -0.21 to 0.80; Pâ=â.25), oxygen consumption (SMD: -0.04; 95% CI: -0.33 to 0.25; Pâ=â.80), resting systolic blood pressure (MD: -2.84; 95% CI: -8.46 to 2.78; Pâ=â.32), systolic blood pressure after exercise (MD: -4.66; 95% CI -15.66 to 6.34; Pâ=â.41), resting diastolic blood pressure (MD: 0.89; 95% CI: -4.41 to 6.19; Pâ=â.74), diastolic blood pressure after exercise (MD: -0.21; 95% CI: -5.51 to 5.10; Pâ=â.94), heart rate (MD: -2.52; 95% CI: -7.76 to 2.73; Pâ=â.35), and arterial oxygen saturation (MD: -0.44; 95% CI: -2.38 to 1.49; Pâ=â.65). No severe adverse effects from nitrate supplementation were reported in the included trails. CONCLUSION: Current evidence suggests that nitrate supplementation may be safe but ineffective for improving exercise tolerance in people with COPD.

Background: Previous studies on the management of chronic subdural hematoma (cSDH) mainly focused on the risk of postoperative recurrence and measures to prevent it. In this study, we propose the use of a non-invasive postoperative treatment method, the modified Valsalva maneuver (MVM), as a means of reducing the recurrence of cSDH. This study aims to clarify the effects of MVM on functional outcomes and recurrence rates. Methods: A prospective study was conducted at the Department of Neurosurgery, Tongji Hospital, Tongji Medical College, Huazhong University of Science and Technology from November 2016 to December 2020. The study included 285 adult patients who underwent burr-hole drainage for the treatment of cSDH and received subdural drains. These patients were divided into two groups: the MVM group (n = 117) and the control group (n = 98). In the MVM group, patients received treatment with a customized MVM device for at least 10 times per hour, 12 h per day. The study's primary endpoint was the recurrence rate of SDH, while functional outcomes and morbidity 3 months after surgery were the secondary outcomes. Results: In the current study, 9 out of 117 patients (7.7%) in the MVM group experienced a recurrence of SDH, while 19 out of 98 patients (19.4%, p < 0.05) in the HC group experienced a recurrence of SDH. Additionally, the infection rate of diseases such as pneumonia (1.7%) was significantly lower in the MVM group compared to the HC group (9.2%, p < 0.001, odds ratio (OR = 0.1). After 3 months of the surgery, 109 out of 117 patients (93.2%) in the MVM group achieved a favorable prognosis, compared to 80 out of 98 patients (81.6%) in the HC group (p = 0.008, with an OR of 2.9). Additionally, infection rate (with an OR of 0.2) and age (with an OR of 0.9) are independent predictors of a favorable prognosis at the follow-up stage. Conclusions: The use of MVM in the postoperative management of cSDHs has been shown to be safe and effective, resulting in reduced rates of cSDH recurrence and infection following burr-hole drainage. These findings suggest that MVM treatment may lead to a more favorable prognosis at the follow-up stage.
RESUMEN
Although sporadic studies have shown that myoglobin may have better prognostic performance than other cardiac markers in COVID-19, a comprehensive comparative study is lacking. Herein, we retrospectively analyzed the clinical and laboratory data of COVID-19 patients admitted to the Guanggu Campus of Wuhan Tongji Hospital from February 9, 2020 to March 30, 2020, intending to compare the prognostic accuracy of three commonly used cardiac markers on COVID-19 mortality. Our results revealed that abnormal increases in myocardial biomarkers were associated with a significantly increased risk of in-hospital mortality with COVID-19. Interestingly, myoglobin, a non-cardiac-specific biomarker, also expressed in skeletal myocytes, had even higher prognostic accuracy than cardiac-specific biomarkers such as high-sensitivity troponin I (hs-TnI) and creatine kinase-MB (CK-MB). More importantly, multivariate Cox analysis showed that myoglobin, rather than hs-TnI or CK-MB, was independently prognostic for in-hospital mortality in COVID-19. These results were further confirmed by subgroup analyses of patients with severe and critical illnesses and those without a history of cardiovascular disease. Our findings suggest that myoglobin may be a reliable marker of illness reflecting general physiological disturbance and help to assess prognosis and treatment response in patients with COVID-19.
RESUMEN
The aim is to explore the relation between inflammation-associated factors and in-hospital mortality and investigate which factor is an independent predictor of in-hospital death in patients with coronavirus disease-2019. This study included patients with coronavirus disease-2019, who were hospitalized between February 9, 2020, and March 30, 2020. Univariate Cox regression analysis and least absolute shrinkage and selection operator regression (LASSO) were used to select variables. Multivariate Cox regression analysis was applied to identify independent risk factors in coronavirus disease-2019. A total of 1135 patients were analyzed during the study period. A total of 35 variables were considered to be risk factors after the univariate regression analysis of the clinical characteristics and laboratory parameters (p < .05), and LASSO regression analysis screened out seven risk factors for further study. The six independent risk factors revealed by multivariate Cox regression were myoglobin (HR, 5.353; 95% CI, 2.633-10.882; p < .001), C-reactive protein (HR, 2.063; 95% CI, 1.036-4.109; p = .039), neutrophil count (HR, 2.015; 95% CI, 1.154-3.518; p = .014), interleukin 6 (Il-6; HR, 9.753; 95% CI, 2.952-32.218; p < .001), age (HR, 2.016; 95% CI, 1.077-3.773; p = .028), and international normalized ratio (HR, 2.595; 95% CI, 1.412-4.769; p = .002). Our results suggested that inflammation-associated factors were significantly associated with in-hospital mortality in coronavirus disease-2019 patients. C-reactive protein, neutrophil count, and interleukin 6 were independent factors for predicting in-hospital mortality and had a better independent predictive ability. We believe these findings may allow early identification of the patients at high risk for death, and can also assist in better management of these patients.

To develop and validate a nomogram using on admission data to predict in-hospital survival probabilities of coronavirus disease 2019 (COVID-19) patients. We analyzed 855 COVID-19 patients with 52 variables. The least absolute shrinkage and selection operator regression and multivariate Cox analyses were used to screen significant factors associated with in-hospital mortality. A nomogram was established based on the variables identified by Cox regression. The performance of the model was evaluated by C-index and calibration plots. Decision curve analysis was conducted to determine the clinical utility of the nomogram. Six variables, including neutrophil (hazard ratio [HR], 1.088; 95% confidence interval [CI], [1.0004-1.147]; p < .001), C-reactive protein (HR, 1.007; 95% CI, [1.0026-1.011]; p = .002), IL-6 (HR, 1.001; 95% CI, [1.0003-1.002]; p = .005), d-dimer (HR, 1.034; 95% CI, [1.0111-1.057]; p = .003), prothrombin time (HR 1.086, 95% CI [1.0369-1.139], p < .001), and myoglobin (HR, 1.001; 95% CI, [1.0007-1.002]; p < .001), were identified and applied to develop a nomogram. The nomogram predicted 14-day and 28-day survival probabilities with reasonable accuracy, as assessed by the C-index (0.912) and calibration plots. Decision curve analysis showed relatively wide ranges of threshold probability, suggesting a high clinical value of the nomogram. Neutrophil, C-reactive protein, IL-6, d-dimer, prothrombin time, and myoglobin levels were significantly correlated with in-hospital mortality of COVID-19 patients. Demonstrating satisfactory discrimination and calibration, this model could predict patient outcomes as early as on admission and might serve as a useful triage tool for clinical decision making.

BACKGROUND: Cavernous hemangioma of the orbit is a benign tumor mostly located behind the eye globe, but it rarely spread into the brain, which is called cerebral cavernous malformation as well, the lesion in the brain is irregular and enlarged blood. Here we report one particular case of craniorbital cavernous hemangioma. CASE PRESENTATION: A 53-year-old woman presented with exophthalmos of the right eye and reduced vision. Computerized tomographical (CT) scan showed osteolytic honeycomb radial changes of the outer plate of the skull. A magnetic resonance imaging (MRI) scan was performed to obtain further details. T1-weighted (T1W) imaging showed slightly low signal mixed with small patchy high signal. T2-weighted (T2W) imaging showed uneven high signal. There was obvious enhancement in the middle and no enhancement in the peripheral bars. A surgically manage was performed using a left frontotemporal approach, the tumor excised fully, and the histopathology results revealed a cavernous hemangioma. The patient recovered well in the follow-up. Post-operative CT scan identified the lesion was successfully resected, MRI scan also showed full resection and enhanced signal from the presence of fat. CONCLUSIONS: Craniorbital cavernous hemangioma is uncommon, however within the cranium, they can lead to numerous complications particularly if affecting the visual apparatus. it could be diagnosed by imaging, which CT scan shows osteolytic honeycomb radial changes of the outer plate of the skull, T1W imaging shows slightly low signal mixed with small patchy high signal, T2W imaging shows uneven high signal, it is obvious enhancement in the middle and no enhancement in the peripheral bars. The surgically manage is the ideally treatment when there are some symptoms.

The coronavirus disease 2019 (COVID-19) pandemic has become a global threat. Increases in cardiac biomarkers are common and are associated with adverse outcomes in patients with COVID-19. Although these increases are more likely to occur in cases with concomitant cardiac disease, the differences in cardiac biomarker levels between patients with and without cardiac disease and their associations with in-hospital mortality are largely unknown. A consecutive serial of laboratory-confirmed COVID-19 cases was retrospectively enrolled. Clinical characteristics, laboratory results, and outcome data were collected. The levels of cardiac biomarkers were evaluated and compared by stratifying patients according to concomitant cardiac conditions and clinical classifications. The prognostic efficacy of cardiac biomarker levels on admission was also assessed. Among the overall study population and survived patients, the cardiac biomarker levels at both the early and late stages in cardiac patients were significantly higher than those in non-cardiac patients. However, their concentrations in cardiac patients were comparable to non-cardiac ones among non-survivors. The cardiac biomarker levels at the late stage of the disease were significantly decreased compared to those at the early stage among patients who were alive. Whereas, the late-stage biomarker levels were significantly increased in patients who ultimately died. Subgroup analysis illustrated that increases in cardiac biomarkers were closely related to the severity of the disease, and were prognostic for high risks of in-hospital mortality in non-cardiac, rather than in cardiac patients. Myo and NT-proBNP, rather than Hs-TnI and CK-MB, were independently associated with in-hospital mortality in the overall population and non-cardiac patients. However, these associations were not significant among cardiac patients. In conclusion, our results helped better understand the release pattern and prognostic performance of cardiac biomarkers in patients with COVID-19. Increased levels of Myo and NT-proBNP on admission could be useful markers for early identifying high-risk patients. However, special attention must be paid when implementing the prognostic function for cardiac patients.
RESUMEN
BACKGROUND: Trigeminal neuralgia (TN) resulting from dural arteriovenous fistulas (DAVFs) is rare. TN caused by a foramen magnum DAVF has not been reported yet. We report a patient with TN caused by a foramen magnum DAVF treated with surgical disconnection. CASE DESCRIPTION: A 35-year-old man was admitted to our hospital with a right TN. Magnetic resonance imaging showed an abnormal flow void in the posterior fossa and a vascular structure next to the root entry zone of the right trigeminal nerve. Digital subtraction angiography showed a Cognard type IV DAVF located at the foramen magnum. The fistula was disconnected surgically. The patient was rendered completely pain-free, and the fistula did not recur during 4-year follow-up. CONCLUSIONS: DAVF is a rare cause of TN. Surgical disconnection is an effective treatment method for TN caused by a foramen magnum DAVF.

BACKGROUND: The optimal approach of blood blister-like aneurysms (BBAs) is debated. Wrapping has been reported to be an effective strategy, but artificial materials have often been used. In addition, perforator protection is difficult using this technique. In this case, we report a ruptured BBA of the left internal carotid artery (ICA) treated with a clip-reinforced wrapping technique using Y-shaped autologous temporalis fascia to protect the posterior communicating artery (PComA). The outcome was favorable. CASE DESCRIPTION: A 48-year-old woman was admitted for subarachnoid hemorrhage. Digital subtraction angiography (DSA) revealed a BBA located opposite the PComA origin. A frontotemporal craniotomy was performed. The temporalis fascia was isolated from the temporalis muscle, and then tailored into a Y shape for the PComA to pass through. The diseased segment and the BBA were then wrapped by the Y-shaped temporalis fascia circumferentially. Two clips were applied to the fascia to reinforce the wrapping to fit snugly enough around the parent artery subsequently. DSA and computed tomography angiography scan postoperation showed that the BBA had not recurred, the supraclinoid segment of the left ICA had reconstructed well, and the PComA was unobstructed. The patient recovered without any sequelae during the 1-year follow-up period. CONCLUSIONS: A clip-reinforced wrapping technique using Y-shaped temporalis fascia may be an effective method for treating BBAs located opposite the PComA origin. Long-term follow-up and large sample size studies, however, are necessary to validate this approach.
