Prediction of hepatocellular carcinoma (HCC) occurrence in patients with chronic hepatitis C (HCV) who achieved a sustained virological response (SVR) after direct acting antivirals (DAAs) remains challenging.

Among HCC-free HCV patients with advanced fibrosis enrolled in the ANRS CO22 HEPATHER cohort who achieved SVR 12 weeks after treatment with DAAs, HCC predictive models were developed using Cox multivariable regression. The derived score was externally validated in a large Egyptian cohort. Our main outcome was the HCC-free survival.

During follow-up (median 3.05 years), 153 out of 3531 patients developed a HCC. Main variables associated with HCC occurrence were male gender, HCV genotype 3, esophageal varices, albumin < 40g/L, total bilirubin >11µmol/L and hypercholesterolemia before DAA initiation, together with age > 58 years, FIB-4 index ≥3.25 evaluated at SVR. A score was established allowing the stratification of patients by high (score ≥ 12/22), intermediate (7 ≤ score <12) and low risk of HCC (score < 7/22) with 3-yrs HCC incidence of 18.96%, 5.50% and 1.65%, respectively. The integrated time-dependent area under the ROC curve (i-AUC) was 0.76 in our patients and 0.61 in the validation cohort.

The externally validated HEPATHER HCC score has good short-term predictive performance in HCV- patients who achieved SVR12 after DAAs allowing to identify high-risk patients in whom HCC screening may be cost-effective and low-risk patients in whom HCC screening may be superfluous in the first 3 years after SVR.

This study investigated the prevalence and characteristics of mcr-1-harbouring Escherichia coli isolated from chickens in central China from 2014 to 2019.

A total of 1132 E. coli isolated from 1647 chicken swabs were analysed for colistin susceptibility by broth microdilution method and prevalence of mcr-1 gene by PCR. The colistin-resistant E. coli isolates were typed by multi-locus sequence typing (MLST) and tested with 12 antimicrobial agents. The transconjugation assay was conducted for the mcr-1-positive isolates using the transconjugant E. coli C600.

Of the 1132 E. coli isolated from chickens, 131 isolates (11.6%) exhibited colistin resistance, and 51 isolates (4.5%) were mcr-1 positive. The mcr-1-positive rate was quite low in 2014 (2.3%) and 2015 (1.7%), increased to peak in 2016 (12.6%) and 2017 (11.4%), and then decreased significantly in 2018 (1.7%) and 2019 (0.9%). The 131 colistin resistant isolates were assigned to 66 unique sequence types (STs), 27 of which contained mcr-1-positive isolates. Compared with mcr-1-negative E. coli, mcr-1-positive E. coli showed higher resistance rates to nalidixic acid, ciprofloxacin, ceftriaxone, cefotaxime, and tetracycline. Furthermore, 30 of the 51 mcr-1 positive isolates transduced their mcr-1 gene into E. coli C600, and 13 of the 30 transconjugants carried more than one replicon types.

The mcr-1 positive rate varied enormously during 2014-2019 in central China. The ban on colistin likely decreased the dissemination of mcr-1 in E. coli isolates from chickens. Multidrug-resistant trait is observed in mcr-1 positive E. coli isolates and can be transferred into other transconjugants.

To describe predominantly persistent intraretinal fluid (PP-IRF) and its association with visual acuity (VA) and retinal anatomic findings at long-term follow-up in eyes treated with pro re nata (PRN) ranibizumab or bevacizumab for neovascular age-related macular degeneration.

Cohort within a randomized clinical trial.

Participants in the Comparison of Age-related Macular Degeneration Treatments Trials (CATT) assigned to PRN treatment.

The presence of intraretinal fluid (IRF) on OCT scans was assessed at baseline and monthly follow-up visits by Duke OCT Reading Center. Predominantly persistent intraretinal fluid through week 12, year 1, and year 2 was defined as the presence of IRF at the baseline and in ≥ 80% of follow-up visits. Among eyes with baseline IRF, the mean VA scores (letters) and changes from the baseline were compared between eyes with and those without PP-IRF. Adjusted mean VA scores and changes from the baseline were also calculated using the linear regression analysis to account for b risk of scar development (adjusted hazard ratio= 1.49; P= 0.03).

Approximately one quarter of eyes had PP-IRF through year 2. Predominantly persistent intraretinal fluid through year 1 was associated with worse long-term VA, but the relationship disappeared after adjustment for baseline predictors of VA. Predominantly persistent intraretinal fluid through year 2 was independently associated with worse long-term VA and scar development.

We retrospectively evaluated the outcome in 28 consecutive patients with CAM who received posaconazole (PCZ) or isavuconazole (ISVCZ) as sole or predominant therapy, based on factors like availability, affordability, site of infection or lack of treatment response. Therapeutic drug monitoring was used for PCZ in all cases & for ISVCZ in some cases. Higher trough levels were aimed to ensure therapeutic effect. Overall, 16 patients were cured, 5 patients improved, 6 patients died, of which 2 deaths were attributable to mucormycosis and 1 patient was lost to follow-up. The outcomes and survival were comparable to those reported in the literature. Although wider applicability of these results cannot be assumed, it leads to a speculation that treatment of mucormycosis with PCZ or ISVCZ, without AmB, is possible.

Following a study of predictors of superinfection in viral respiratory tract infections (VRTIs), this study analyzes the predictors of the outcome.

Multicenter retrospective study conducted among adults who tested positive for VRTIs with reverse-transcription polymerase chain reaction. We compared characteristics between influenza virus, Paramyxoviridae, and Pneumoviridae and identified predictors of favorable short-term outcome, admission to the intensive care unit (ICU), and mortality.

A total of 590 patients had VRTI, including 347 (59%) influenza infections. Mean (SD) patient age was 71.0 (18.3) years, with a sex ratio of 0.91. In multivariate analyses, predictors of favorable short-term outcome were age ≤75 years (adjusted odds ratio [aOR] 5.38 [95% confidence interval, 1.59-18.2]), absence of respiratory disease (4.94 [1.01-24.37]), and absence of superinfection (aOR 3.91 [1.37-11.13]). The predictors of ICU admission were age ≤75 years (aOR 3.28 [1.71-6.25]), chronic respiratory disease (aOR 2.49ion of individuals at risk of VRTIs.Equine herpesvirus-1 (EHV-1) myeloencephalopathy (EHM) is a devastating consequence of EHV-1 infection that has significant economic consequences. However, clinical EHM is relatively rare and occurs in only approximately 10% of infected horses. While there is a positive correlation between the duration and magnitude of viremia and incidence of EHM, it is likely that a combination of host and viral factors determine whether EHM occurs. The identification of these factors is of high interest for the equine community and has been the topic of much research for vaccine development and to predict which horses might be most at risk for developing EHM. The aim of this review is to highlight host immunity contributions to EHM pathogenesis at different sites of EHV-1 infection to shed light on the different aspects and interdependence of the response to EHV-1 in the time course of infection.

The molecules released from cells undergoing necrosis are recognized as alarmins, and S100A8/9, a typical alarmin, is associated with several inflammation-related diseases. This study was to investigate the molecular role of S100A8/A9 on the process of intervertebral disc degeneration (IVDD) and inflammation-related pain.

The expression pattern of S100A8/A9 in different degenerated human nucleus pulposus (NP) tissues were measured by Real-time quantitative reverse transcription PCR (RT-qPCR) and immunohistochemical (IHC). The effects of S100A8/A9 on matrix production were assessed by RT-qPCR, western blotting, and cell immunofluorescence. Involvement of TLR4 and NF-κB signaling pathways were studied by pharmachemical inhibitors and small interfering RNAs (siRNAs). The development of degenerative and pain features in the IVDD model were examed by IHC and pain-behavior testing.

The expression of S100A8/A9 was significantly elevated in severely degenerated human NP tissue with similar expression pattern of TNF-α. In NP cells, S100A8/A9 increased MMP-3/13, TNF-α, IL-6 expression and inhibited aggrecan and collagen II expression. RT-qPCR and western blotting showed that the regulatory effects of S100A8/A9 on IVD were TLR4 dependent. Pharmacological inhibition or siRNA knockdown of the NF-κB signaling attenuated S100A8/A9-induced upregulation of MMP-3/13, TNF-α and IL-6. In vivo, S100A9 inhibitor treatment inhibited disc-puncture induced IVDD and inflammation-related pain.

This study showed that S100A8/A9 bound to TLR4 and increased the expression of MMPs, TNF-α, and IL-6 through NF-κB signaling pathways in NP cells. Furthermore, S100A8/A9 inhibitor could prevent development of IVDD and inflammation-related pain in the rat model.

To assess the association between higher-than-normal BMI and incidence of premenopausal ovarian and breast cancers.

This prospective cohort study included 461,646 women registered in the Danish Medical Birth Registry with self-reported early adulthood BMI ≥18.5 kg/m

, without a history of cancer. We used Cox proportional hazards regression models to estimate the hazard ratios (HRs) with 95% confidence intervals (95% CIs) of premenopausal epithelial ovarian cancer, breast cancer, estrogen receptor positive and negative, HER2 positive and negative breast cancers according to BMI.

Compared with normal weight, obesity was associated with higher rates of premenopausal ovarian cancer (HR=1.95, 95% CI 1.19-3.21) when adjusted for parity, use of hormonal contraception, family history of ovarian and/or breast cancer, other cancer, and calendar year. Obesity was associated with lower rates of premenopausal breast cancer (HR=0.77, 95% CI 0.68-0.87) when adjusted for parity, use of hormonal contraception, family history of ovarian and/or breast cancer, any other cancer, calendar year, smoking, and highest achieved education.
