Gastrointestinal bleeding as the first sign of Brunner's gland adenoma (BGA) is an extremely rare, and its clinical features and treatment methods have not been well described. ⋯ Endoscopic removal is considered as a safe and low-risk treatment for elderly patients with severe underlying diseases presenting with gastrointestinal bleeding.

We examined whether the age of patients with rheumatoid arthritis was associated with adverse events (AEs) caused by biologic disease-modifying antirheumatic drugs (bDMARDs). Patients with rheumatoid arthritis using bDMARDs from Showa University Hospital, Showa University Northern Yokohama Hospital, and Showa University Koto Toyosu Hospital from January 2005 to December 2017 were eligible for this retrospective cohort study. The maximum observation period was determined to be 1 year. ⋯ The rates of drug discontinuation because of AEs caused by bDMARDs were 10.5% (7/67) in patients 75 years and older and 10.9% (38/349) in those younger than 75 years (relative risk 0.95, 95% confidential interval 0.45-2.24). In logistic regression analysis adjusted for covariates, the rate of drug discontinuation showed no significant difference between the patients ≥ 75 years and the those < 75 years (adjusted odds ratio 0.70, 95% confidential interval 0.29-1.75, P = .45). The rate of drug discontinuation because of AEs caused by bDMARDs was not significantly different between patients 75 years and older and patients younger than 75 years.

Guillain-Barré syndrome (GBS) is an acute autoimmune neurological disorder mainly involving the peripheral nerves. Currently, various cytokines have been shown to be involved in the pathogenesis of GBS. Because of their similar biological structures, interleukin (IL)-36α, IL-36β, IL-36γ, and IL-36 receptor antagonist (Ra) were all renamed and collectively called IL-36 cytokines. ⋯ Similar results were observed in cerebrospinal fluid (CSF), IL-36α and IL-36γ levels in CSF were positively correlated with GDSs, while IL-36Ra levels in CSF were negatively correlated with GDSs. Additionally, the serum and CSF levels of IL-36α and IL-36γ in the axonal subtype of GBS patients were higher than those in the demyelination subtype. Based on our findings, IL-36 cytokines may be involved in the pathogenesis of GBS and some of these cytokines may help predict the disease severity and other clinical characteristics of GBS.

To investigate whether MRI features could preoperatively predict local tumor progression (LTP) in patients with hepatocellular carcinoma (HCC) treated with radiofrequency ablation (RFA) as the first-line treatment and improve a novel predictive model through developing a nomogram including various conventional MRI parameters. 105 patients with HCCs who had received RFA were enrolled. All patients had undergone conventional MRI before RFA. Uni- and multivariable analyses for LTP were assessing using a Cox proportional hazards model. ⋯ The performance of the nomogram incorporating two MRI parameters (with a C-index of 0.782) was improved compared with that based on rim enhancement and ADC alone (with C-index values of 0.630 and 0.728, respectively). The calibration curve of the MRI-based nomogram showed good conformance between evaluation and observation at 0.5, 1, and 1.5 years after RFA. The preliminary predictive model based on MRI findings including rim enhancement and ADC value could be used preoperatively to estimate the risk of LTP of HCC after RFA as the first-line treatment.

This study aimed to investigate the effects of age on the peak ratio (PR) of ophthalmic artery (OA) Doppler. The initial peak velocity (P1), second peak velocity (P2) and PR of OA were detected by color Doppler ultrasonography in 147 healthy subjects. All of the subjects were divided into 6 groups (G1-G6) according to the age. (G1, 20-29 years; G2, 30-39 years; G3, 40-49 years; G4, 50-59 years; G5, 60-69 years; and G6, 70 years or older). ⋯ PR also had a weak relationship with systolic blood pressure. Both P2 and PR of OA Doppler increase with age. Concern should be raised when P2 and PR are used to evaluate the hemodynamic change of OA.
