2% of cases. The study identified specific factors associated with lower consistency and accuracy.
Diagnosis was highly consistent across time and moderately between examiners. Accuracy was almost perfect for stage and moderate for grade and extent. Additional efforts are required to improve training of general dentists.

We investigated whether species of circulating cell-free DNA (cfDNA) may be involved in the process of hepatocarcinogenesis in treated CHB patients. Serum samples were obtained from HBeAg-negative CHB patients with (HCC cases, n = 37) or without HCC development during the first 5 years of oral antiviral therapy (controls, n = 74). HCC cases and controls were matched 12 for age, sex and platelets. Determination of different circulating cfDNA species (before HCC diagnosis in HCC cases) including total cfDNA quantity, levels of Alu repeat DNA and RNase P coding DNA, copies of mitochondrial DNA and levels of 5-methyl-2′-deoxycytidine as an indicator of DNA methylation was performed. HCC cases compared with controls had higher median levels of Alu247 (123 vs 69 genomic equivalent, p = .042) and RNase P coding DNA (68 vs 15 genomic equivalent, p less then .001). In contrast, median cfDNA concentration, Alu115 levels, Alu247/Alu115 ratio as an index of DNA integrity and mitochondrial DNA copies did not differ significantly between HCC cases and controls. Receiver operating characteristic curve analysis showed that levels RNase P coding DNA offered good prediction of subsequent HCC development (c-statistic 0.80, p less then .001). In conclusion, serum levels of RNase P coding DNA are increased years before HCC diagnosis and could be potentially helpful in the prediction of the HCC risk in treated HBeAg-negative CHB patients.
Mild behavioural impairment (MBI) is a neurobehavioural syndrome characterized by emergent neuropsychiatric symptoms in later life. mTOR inhibition There has been no systematic review or meta-analysis on the prevalence of MBI. The main aim of the study is to calculate the pooled prevalence of MBI.
A search of the literature on MBI in mild cognitive impairment (MCI), cognitively normal (CN), and subjective cognitive impairment (SCI) and CN but at risk (CN-AR) subjects published between 1 January 2003 and 28 September 2020 was conducted. Meta-analysis using a random effects model was performed to determine the pooled estimate of the prevalence of MBI. Meta-regression was performed to identify factors contributing to the variance of prevalence rate. A systematic review was also performed to study the impact of MBI in cognitive outcomes and its correlation to the pathology and genetics of Alzheimer’s disease.
Eleven studies conducted among 15 689 subjects underwent meta-analysis, revealing the pooled prevalence of MBI to be 33.5% (95% confidence interval (CI) 22.6%-46.6%). Seven studies conducted among 1358 MCI subjects underwent meta-analysis, revealing the pooled prevalence to be 45.5% (95%CI 36.1%-55.3%). Four studies conducted among 13 153 CN subjects underwent meta-analysis, revealing the pooled prevalence to be 17.0% (95%CI 7.2%-34.9%). Five studies conducted among 1158 SCI or CN-AR subjects underwent meta-analysis, revealing the pooled prevalence to be 35.8% (95%CI 21.4%-53.2%). A systematic review of 13 studies showed that MBI has a significant impact on cognitive deterioration and is associated with the pathology and genetics of Alzheimer’s disease.
In MCI, CN, and SCI and CN-AR subjects, MBI is common. Our finding is potentially useful in planning future clinical trials.

To evaluate and describe brainstem auditory-evoked response measurements in healthy African pygmy hedgehogs (Atelerix albiventris).
Brainstem auditory-evoked response measurements were performed in 12 adult African pygmy hedgehogs (seven males, five females) under general anaesthesia. Waveform morphology was assessed and wave latencies, amplitudes and interpeak latencies calculated.
Brainstem auditory-evoked response measurements were successfully performed in both ears from all hedgehogs. Three distinct waves were reproducible in all patients in both ears using a stimulus with an intensity of 90 dB nHL (decibel above normal hearing level). Amplitudes of waves I and V, latencies of waves I, II-III and V and interpeak latencies of waves I-V were calculated at 90 dB for both ears of each animal.
This study describes normal brainstem auditory-evoked response morphology and latencies for African pygmy hedgehogs. General anaesthesia is required to perform this neurodiagnostic, given the unique behaviour and anatomy of hedgehogs. This baseline data may be useful for investigating hearing abnormalities and central nervous system disorders in hedgehogs.

To develop a logistic regression model, artificial neural network (ANN) model and decision tree (DT) model for the progression of mild cognitive impairment (MCI) to Alzheimer’s disease (AD) to compare the performance of the three models.
A total of 425 patients with MCI were screened from the original cohort. The actual follow up included 361 patients, with AD as the outcome variable. Three kinds of prediction models were developed a logistic regression model, ANN model and DT model. The performance of all three models was measured with accuracy, sensitivity, positive predictive value and area under the receiver operating characteristic curve.
A total of 121 patients with MCI developed AD, and the average conversion rate was 9.49% per year. The ANN model had higher accuracy (89.52 ± 0.36%), area under the receiver operating characteristic curve (92.08 ± 0.12), sensitivity (82.11 ± 0.42%) and positive predictive value (75.26 ± 0.86%) than the other two models. The first five important predictors of the ANN model were, in order, ADL score, age, urine AD-associated neuronal thread protein, alcohol consumption and smoking.
