Assessment of efficacy and prognostic factors by Gelfoam for DEB-TACE in unresectable large hepatocellular carcinoma with portal vein tumor thrombus: a multi-center retrospective study.

OBJECTIVE: To explore the clinical efficacy and prognostic factors of the use of Gelfoam for drug-eluting bead (DEB) transarterial chemoembolization (GMD-TACE) in patients with unresectable large hepatocellular carcinoma (HCC) and portal vein tumor thrombus (PVTT). METHODS: A retrospective analysis was conducted using the mRECIST standard to evaluate tumor response after GMD-TACE. Overall survival time, median survival time, time to progression (TTP) after the first intervention, and other treatment methods were recorded. RESULTS: The follow-up time was 2-110 months (mean 17.97 + 19.12 months), the median follow-up time was 12.5 months, and the first TTP after the first GMD-TACE was 4 months (95% CI 3.020-4.980). The median overall survival (OS) time was 14 months (95% CI 9.801-18.199). The 1-, 3-, and 5-year survival rates were 53.6%, 32.3%, and 8.9%, respectively. Multivariate analysis showed that the type of tumor thrombus was an independent factors affecting prognosis, and combination therapy was a protective factor affecting prognosis. CONCLUSIONS: GMD-TACE can be used as the core treatment for unresectable large HCC combined with a PVTT. This can improve the quality of life and further improve the median OS, and is worthy of clinical promotion and application.

Gut microbiota interacts with intrinsic brain activity of patients with amnestic mild cognitive impairment.

AIMS: To explore the potential relationships among gut microbiota (GM), local brain spontaneous activity, and neuropsychological characteristics in amnestic mild cognitive impairment (aMCI) patients. METHODS: Twenty aMCI and 22 healthy control (HC) subjects were recruited. The GM composition was determined by 16S ribosomal RNA gene sequencing. Resting-state functional magnetic resonance imaging scans were performed, and fractional amplitude of low-frequency fluctuations (fALFF) was calculated across different frequencies. The Spearman or Pearson correlation analysis was used to analyze the relationship between spontaneous brain activity and cognitive function, and GM composition. RESULTS: aMCI patients had altered GM state and local spontaneous brain activity as compared with HC subjects. Correlation analysis showed that aMCI and HC groups had different "GM-intrinsic brain activity interaction" patterns. In aMCI group, at the typical band (0.01-0.08 Hz), the relative abundance (RA) of Bacteroides from phylum to genus level was negatively correlated with fALFF value of cerebellar vermis IV-V, and the Ruminococcaceae RA was negatively correlated with fALFF values of left lenticular nucleus and pallidum. The Clostridiaceae RA and Blautia RA were positively correlated with the left cerebellum lobules IV-V at the slow-4 band (0.027-0.073 Hz). The Veillonellaceae RA was positively correlated with fALFF values of left precentral gyrus at the slow-5 band (0.073-0.08 Hz). Correlation analysis showed that Clostridium members (Lachnospiraceae and Blautia) were positively, while Veillonellaceae was negatively, correlated with cognition test. Bacteroides was positively correlated with attention and computation, and negatively correlated with the three-stage command score. CONCLUSIONS: aMCI patients have a specific GM-intrinsic brain activity-cognitive function interaction pattern.

Cilostazol plus clopidogrel in the prevention of in-stent stenosis after vertebral artery origin stenting in gout patients: three case reports.

It is unclear whether cilostazol instead of aspirin in combination with clopidogrel could prevent in-stent thrombosis in patients with a history of gout undergoing vertebral artery origin stenting. Three men (age range, 58-74 years) were diagnosed with acute ischaemic stroke or transient ischaemic attack. Vertebral artery origin stenosis was visible by computed tomographic angiography or digital subtraction angiography. Four bare metal stents were placed in the vertebral artery origin. The patients were administered 100 mg cilostazol orally twice a day and 75 mg clopidogrel orally once a day perioperatively and 100 mg cilostazol orally twice day was administered indefinitely after 3 months. No in-stent stenosis was observed in all of these patients during a follow-up period up to 19 months. Cilostazol plus clopidogrel has the potential to become an alternative to standard dual antiplatelet therapy in vertebral artery origin stenting. A high-quality clinical trial is needed to verify these preliminary findings.

Rise in Low-Density Lipoprotein Cholesterol during Hospitalization is Related with Poor Outcome at Discharge in Patients with Acute Ischemic Stroke.

BACKGROUND: The statistical association between a short-term rise in low-density lipoprotein cholesterol (LDL-C) levels and the short-term outcome of acute ischemic stroke remains unknown. We aimed to evaluate the association in acute ischemic stroke patients during hospitalization. METHODS: Patients with acute ischemic stroke who received statin at discharge were enrolled in this multicenter registry study. LDL-C values were measured on the first day after admission and on the day before discharge to determine the rise in LDL-C levels. Poor outcome was defined as a modified Ranking Scale score ≥2 at discharge. The National Institutes of Health Stroke Scale increase from admission to discharge by 2 points was defined as clinical deterioration. Logistic regression analyses were used to analyze the relationship between LDL-C rise during hospitalization and poor outcome at discharge. Variables that were significantly different between the LDL-C rise and LDL-C fall groups were considered in adjustment for confounding variables in model 1. Age, sex, and those variables in model 1 were considered in adjustment for confounding variables in model 2. RESULTS: Among the 676 patients, 110 (16.3%) showed a rise in LDL-C levels during hospitalization. Multivariate analyses showed that LDL-C at admission <1.6 mmol/L was significantly correlated with LDL-C rise during hospitalization (p < 0.001). There were significantly more patients with a poor outcome in the "LDL-C rise" group than in the "LDL-fall" group (p = 0.002). Multiple models consistently showed that LDL-C rise increased the risk of a poor outcome at discharge in model 1 (OR [95% CI] 1.351 [1.059-1.723], p = 0.016) and model 2 (OR [95% CI] 1.370 [1.071-1.751], p = 0.012). LDL-C rise also increased the risk of clinical deterioration, although its p value only was 0.043 in model 1 and 0.048 in model 2. CONCLUSIONS: Rise in LDL-C during hospitalization from acute ischemic stroke is an independent predictor of poor outcome at discharge. In particular, patients with lower LDL-C values at admission are a higher at risk, and LDL-C in these patients should thus be monitored while in hospital.

A Grading Scale for Pial Collaterals in Middle Cerebral Artery Total Occlusion Based on Time-of-flight MR Angiography Source Images.

PURPOSE: To verify whether a new grading based on time-of-flight magnetic resonance angiography source images (TOF-MRAsi) can reflect the abundance of pial collaterals, in patients with total occlusion of M1 segment of middle cerebral artery in the chronic stage. METHODS: In this single-center retrospective study, consecutive patients with total occlusion of M1 segment of middle cerebral artery, with both magnetic resonances angiography and digital subtraction angiography image were included. Time-of-flight magnetic resonance angiography source images were evaluated in a blinded fashion for pial collaterals (PCs) that were graded on a four-point scale. Good and poor PCs were defined as TOF-MRAsis grade <2 and ≥2, respectively. Receiver operating characteristic curve analysis was done to calculate the area under curve, sensitivity, and specificity. RESULTS: A total of 26 patients were included. The inter-reader agreement for time TOF-MRAsi and digital subtraction angiography images were 0.930 and 0.843, respectively. Compared with digital subtraction angiography grading, the area under curve of pial collateral grading based on TOF-MRAsi was 0.830 (0.636-1.000; P = 0.006). The sensitivity and specificity were 0.700 and 0.933, respectively. The modified Rankin Scale at follow-up was lower in patients with good PCs than in those with poor PCs (0[0, 1] vs. 1[1, 3], P = 0.055), although statistical significance was not reached. CONCLUSION: The grading scale based on TOF-MRAsi could be a new empirical approach for pial collateral evaluation. The clinical use of the proposed approach for identifying patients with total occlusion of middle cerebral artery with a high risk of poor outcome requires evaluation in further studies.

Intensive Versus Moderate Statin Therapy Discontinuation in Patients With Acute Ischemic Stroke or Transient Ischemic Attack.

PURPOSE: The differences of discontinuation risk between intensive and mild-to-moderate statin therapy in patients with acute ischemic stroke is not clear. This study aimed to clarify whether intensive statin therapy resulted in a significant increase in discontinuation early after discharge. METHODS: This multicenter registry study enrolled consecutive hospitalized patients with ischemic stroke or transient ischemic attack. All the patients were prescribed statin therapy at discharge. Intensity of statin therapy was defined according to the 2013 American College of Cardiology/American Heart Association guideline on the treatment of blood cholesterol. A logistic regression model was used to analyze the association between statin therapy intensity and discontinuation. FINDINGS: This study included 505 patients, of whom 64 and 441 received intensive and moderate statin therapy, respectively (mean follow-up, approximately 6 months). The rates of discontinuation of intensive and moderate statin therapy were 31.3% and 10.7% (P < 0.001), respectively. Variables with significant differences between the intensive and moderate statin therapy groups were included in the adjusted logistic regression model. Intensive statin therapy significantly increased discontinuation risk by 273.0% (odds ratio = 3.730; 95% CI, 2.013-6.911; P < .001) compared with moderate statin therapy. The result was consistent in most subgroups, except for patients with National Institutes of Health Stroke Scale scores ≥4. IMPLICATIONS: In stroke secondary prevention, intensive statin therapy may significantly increase the risk of early discontinuation compared with moderate statin therapy. Future clinical trials that involve a comparison between intensive and moderate statin therapy for stroke secondary prevention should address the differences in discontinuation between these 2 groups.

Age and composite end-point events in medium follow-up of patients with carotid artery total occlusion using drug therapy.

BACKGROUND AND AIMS: The outcome of carotid artery total occlusion (CATO) is unclear. The aim of this study is to report the medium incidence of composite end-point events and risk factors (especially age), in patients with CATO, treated medically. METHODS: This was a single center retrospective study. Composite end-point events included death, ischemic stroke, transient ischemic attack, hemorrhagic stroke, myocardial infarction, or angina. Logistic regression analysis was used to analyze risk factors of composite end-point events. RESULTS: A total of 94 patients with CATO were included in the study. The mean follow-up duration was 30 ± 16 months. There were 16 cases who experienced composite end-point events (17.0%); among them, there were 15 cases of death (16.0%), 8 cases of ischemic stroke (7 cases of fatal stroke and 1 case of non-fatal stroke) (8.5%), and 1 case of angina pectoris (1%) (the patient later developed ischemic stroke). With increased age, the incidence of composite end-point events was significantly increased (p = 0.002). Multivariate logistic regression analysis showed that only age was a risk factor (OR = 3.051 (1.351-6.890), p = 0.007). CONCLUSIONS: The incidence of composite end-point events in patients with CATO was as high as 17.0% at approximately 3 years after drug therapy alone. For every 10 years of age increase, the risk increase of composite end-point events doubles.

A model to predict the onset of non-alcoholic fatty liver disease within 2 years in elderly adults.

BACKGROUND AND AIM: Non-alcoholic fatty liver disease (NAFLD) is a common cause of chronic hepatitis, which leads to cirrhosis and hepatocellular carcinoma. However, it is difficult to identify subjects at high risk for NAFLD onset. This study aims to construct a model to predict the onset of NAFLD within 2 years in elderly adults. METHODS: This study included and followed 3378 initial NAFLD-free subjects aged 60 years or over for 2 years, which were randomly divided into a training set and a validation set. NAFLD was diagnosed on ultrasound. Clinical and laboratory data were recorded at baseline. A model was constructed in the training set to predict the onset of NAFLD and validated in the validation set. RESULTS: Body mass index, hemoglobin, fasting blood glucose, and triglycerides were identified as predictors for the onset of NAFLD. A risk score (R) was calculated by them. It classified the subjects into low-risk group (R ≤ -2.88), moderate-risk group (-2.88 < R ≤ -1.26), and high-risk group (R > -1.26). In the training set, 4.68% of the participants in the low-risk group, 11.59% of the participants in the moderate-risk group, and 31.02% of the participants in the high-risk group developed NAFLD. In the validation set, 5.84% of the participants in the low-risk group, 10.57% of the participants in the moderate-risk group, and 29.44% of the participants in the high-risk group developed NAFLD. CONCLUSIONS: This study developed a model to predict the onset of NAFLD in elderly adults, which might provide indications for intervention to these subjects.

[Oxidative stress in patients with chronic hepatitis B].

BACKGROUND: To study oxidative stress in patients with chronic hepatitis B. METHODS: Malondialdehyde (MDA), total anti-oxidative ability and ascorbic acid were measured as markers of oxidative stress in 30 patients with chronic hepatitis B, besides HBV DNA and ALT. RESULTS: MDA was significantly higher in patients with hepatitis B than the controls (P less than 0.05). Ascorbic acid was significantly higher in patients with normal ALT than the controls (P less than 0.01). MDA was significantly higher in patients with increased ALT than the controls and in patients with normal ALT. MDA was significantly positively correlated with ALT (r=0.61), and ascorbic acid was significantly negatively correlated with ALT (r=-0.64) in patients with hepatitis B. No significant relationship was found between HBV DNA and other indices of oxidative stress. No significant difference in total anti-oxidative ability was found among all groups. CONCLUSION: There was a disturbance between oxidative stress and anti-oxidative ability in patients with chronic hepatitis B. In patients with increased ALT, oxidative stress became high. In patients with normal ALT, oxidative stress level was low. The indices of oxidative stress should be detected in patients with hepatitis B, in addition to HBV markers.
