markers can help refine patient selection for immunotherapy. In patients with unresectable hepatocellular carcinoma (HCC), the combination of atezolizumab and bevacizumab improved progression-free survival (PFS) and overall survival compared with sorafenib in the IMbrave150 trial. However, whether the price of the combination could be affordable is unknown. The current study assessed the cost-effectiveness of the combination of atezolizumab and bevacizumab as first-line systemic therapy for patients with unresectable HCC from the Chinese and American payers' perspective. A Markov model was built based on a global, multicentre, open-label, phase III randomized trial (IMbrave150, NCT03434379) that included three states of the patient's health stable disease (SD), progressive disease (PD) and death. Data for all medical costs were acquired from the Red Book, published literature and West China Hospital. Quality-adjusted life years (QALYs) and incremental cost-effectiveness ratios (ICERs) were the primary outcomes. Sensitivity analyses were performed to evaluate the model uncertainty. The treatment consisting of a combination of atezolizumab and bevacizumab yielded an additional 0.53 QALYs compared with sorafenib alone, leading to an ICER of $145,546.21 per QALY in China and $168,030.21 per QALY in the USA, both beyond the willing-to-pay threshold ($28,527.00/QALY in China and $150,000.00 /QALY in the USA). The utility of the PD state was the most influential factor in the Chinese model, and the American model was the most sensitive to the price of sorafenib. The results of the models were robust across sensitivity analyses. The combination of atezolizumab and bevacizumab was not a cost-effective strategy for the first-line systemic treatment of unresectable HCC from the Chinese and American payers' perspective.

This report describes a severe case of nivolumab/ipilimumab-associated glutamic acid decarboxylase 65-positive autoimmune encephalitis. It proposes neurofilament light chain levels, a biomarker indicating axonal damage, in the cerebrospinal fluid and serum as a putative novel biomarker for this diagnostically and therapeutically challenging entity with an often unfavorable outcome. Additionally, we provide an overview of previous reports of patients developing autoimmune encephalitis under ICI treatment.The imbalance between ultrafiltration volume (UF) and vascular refilling is considered a major cause for intradialytic hypotension. Recent studies report a noninvasive method to estimate vascular refilling (VREF ) by determining absolute blood volume (ABV). It was the aim of the study to analyze variations in ABV in a group of hemodialysis (HD) patients and examine VREF . Thirty one stable chronic HD patients were studied, aged 71.07 ± 13.31 years. Dialysis duration and UF requirements were based on physician prescription. VREF was calculated as VREF = VUF - ΔV where ΔV is ABV variation during dialysis treatment. ABV at the beginning of the dialysis was 6.00 ± 2.39 L (92.82 ± 33.17 ml/kg) and at the end 5.38 ± 2.32 L (82.07 ± 31.41 ml/kg). Prescribed UF was 2.64 ± 0.83 L. https://www.selleckchem.com/products/atezolizumab.html Mean VREF was 2.05 ± 0.80 L, with a refilling fraction of 75.75 ± 12.79%. VREF was strongly correlated with UF volume (r2 0.877), and with pre-dialysis volume overload (r2 0.617). Patients under beta-blocker treatment showed significantly lower FREF . ABV measurement is an easy and noninvasive method that allows us to study VREF during HD. We found a strong correlation between VREF and UF. Recently, there has been growing interest in the glymphatic system (the functional waste clearance pathway for the central nervous system and its role in flushing solutes (such as amyloid ß and tau), metabolic, and other cellular waste products in the brain. Herein, we investigate a recent potential biomarker for glymphatic activity (the diffusion tensor imaging along the perivascular space [DTI-ALPS] parameter) using diffusion MRI imaging in an elderly cohort comprising 10 cognitively normal, 10 mild cognitive impairment (MCI), and 16 Alzheimer's disease (AD). All 36 participants imaged on a Siemens 3.0T Tim Trio. Single-SE diffusion weighted Echo-planar imaging scans were acquired as well as T1 magnetization prepared rapid gradient echo, T2 axial, and susceptibility weighted imaging. Three millimeter regions of interest were drawn in the projection and association fibers adjacent to the medullary veins at the level of the lateral ventricle. The DTI-ALPS parameter was calculated in these regions and correlated with cognitive status, Mini-Mental State Examination (MMSE), and ADASCog11 measures. Significant correlations were found between DTI-ALPS and MMSE and ADASCog11 in the right hemisphere adjusting for age, sex, and APoE ε4 status. Significant differences were also found in the right DTI-ALPS indices between cognitively normal and AD groups (P < .026) and MCI groups (P < .025) in a univariate general linear model corrected for age, sex, and APoE ε4. Significant differences in apparent diffusion coefficient between cognitively normal and AD groups were found in the right projection fibers (P = .028). Further work is needed to determine the utility of DTI-ALPS index in larger elderly cohorts and whether it measures glymphatic activity.

The objective of this systematic review and meta-analysis was to assess the impact of DAAs on CHC progression and mortality. We searched Ovid MEDLINE, Ovid EMBASE and PubMed databases (January 2011 to March 2020) for studies that compared the efficacy of DAAs to a non-DAA control in patients with CHC. Main outcomes were the adjusted hazard ratios (HRs) for mortality, liver decompensation, HCC occurrence and recurrence. Pooled estimates of HRs were determined using random-effects meta-analyses with inverse variance weighting, with sensitivity analyses and meta-regression to explore the effects of clinical factors. We identified 39 articles for the primary analysis. Compared with unexposed individuals, patients treated with DAA had a reduced risk of death (HR; CI = 0.44; 0.38-0.52), decompensation (HR; CI = 0.54; 0.38- 0.76) and HCC occurrence (HR; CI = 0.72; 0.61- 0.86). The protective effect of DAA on HCC recurrence was less clear (HR; CI = 0.
