The gut microbiome is altered in cirrhosis. Recent evidence has suggested a key role for the gut microbiota in the progression of cirrhosis and the development of hepatocellular carcinoma (HCC). We studied the differences in the microbial composition in patients with cirrhosis with prior and future HCC in the context of other complications (eg, infections, hepatic encephalopathy). The following 2 cohorts were recruited prospectively the prior HCC cohort, in which outpatients with HCC within 2 years were age-matched, sex-matched, and Model for End-Stage Liver Disease (MELD) score-matched with those without HCC; and the future HCC cohort, in which patients were followed for 2 years and divided into future HCC versus no HCC after age, sex, and MELD-score matching and other complications were also recorded. Microbiota composition and predicted function were analyzed with ribosomal RNA sequencing and Phylogenetic Investigation of Communities by Reconstruction of Unobserved States (PiCRUST)and compared between (1) ther complications. Despite age, sex, and MELD-score matching and accounting for other complications, gut microbiota composition and the predicted function are different in men with cirrhosis with and without prior HCC and can be extended toward future HCC development.

Serum neurofilament light (sNfL) is a promising new biomarker in multiple sclerosis (MS). We explored the relationship between sNfL and health outcomes and resource use in MS patients.

MS patients with serum samples and health-outcome measurements collected longitudinally between 2011 and 2016 were analyzed. sNfL values were evaluated across age and gender. Data were analyzed using correlation with log-transformed sNfL values.

A total of 304 MS patients with a mean age of 32.9years, average EDSS of 1.6 (SD=1.5) and baseline sNfL of 8.8 (range 1.23-78.3) pg/mL were studied. Baseline sNFL values increased with age and were higher in females. Baseline sNfL correlated with baseline Multiple Sclerosis Quality of Life physical composite (mean=49.4 (9.1), P=0.035) and baseline EDSS (P=0.002). Other PRO measures at baseline did not show a significant relationship with baseline sNfL. Average of baseline and follow-up sNfL correlated with MSQoL physical-role limitations (mean=48.9 (10.8), P=0.043) and social-functioning (mean=52.3 (7), P=0.034) at 24-month follow-up. We found a trend for numerically higher sNfL levels in nonpersistent patients compared to those who were persistent to treatment (11.13 vs. 8.53pg/mL, P=0.093) measured as average of baseline and 24-month values. Baseline NfL was associated with number of intravenous steroid infusions (mean=0.2; SD=3.0, P=0.013), whereas the average of baseline and 12months NfL values related to inpatient stays at 12months (mean=0.2; SD=3.0 P=0.053).

Serum NfL is a patient-centric biomarker that correlated with MS patient health-outcomes and healthcare utilization measures in a real-world cohort.

In the present study, we have clearly shown that the foot-and-mouth disease virus (FMDV) promotes ID1 degradation via Cdh1-mediated ubiquitination to facilitate its replication. Mechanistic investigations reveal Forkhead Box O1 (FOXO1) as an ID1 partner, which suppresses interferon regulatory factors 3 expression and interferon (IFN) production. Further investigation identified that ID1 suppresses FOXO1 transcription activity through HDAC4-mediated deacetylation, promoting IFN production and antiviral immune response. These studies establish a prominent role for ID1 in suppressing FDMV replication, which may be extended to other viruses.The stratum corneum (SC) of the epidermis acts as a skin permeability barrier, and abnormalities in SC formation lead to several skin disorders. Lipids, especially the epidermis-specific ceramide classes ω-O-acylceramides (acylceramides) and protein-bound ceramides, are essential for skin barrier formation. this website Ceramide synthase 3 (CERS3) is involved in the synthesis of acylceramides and protein-bound ceramides, and CERS3 mutations cause autosomal recessive congenital ichthyosis. In the present study, we measured ceramide synthase activity and performed comprehensive SC ceramide profiling in an ichthyosis patient with compound heterozygous CERS3 mutations nonsense mutation p.Arg75* and missense mutation p.Arg229His. The activity of p.Arg75* and p.Arg229His mutant CERS3 proteins was reduced to 4% and 56%, respectively, of the wild-type protein. In the patient's SC, acylceramide levels were greatly reduced, but the levels of protein-bound ceramides remained almost unchanged. Non-acylated ceramide levels were also affected in the patient; in particular, the levels of ceramides composed of sphingosine and non-hydroxy or α-hydroxy fatty acid were substantially higher than in healthy controls. These results suggest that a reduction in acylceramide levels alone leads to ichthyosis. Although protein-bound ceramides are synthesized from acylceramides, levels of acylceramides and protein-bound ceramides are not necessarily correlated.

Despite the causal relationship between obesity and colon cancer being firmly established, the effect of obesity on the course of cancer calls for further elucidation. The objective of this study was to assess differences in clinical-pathological and psychosocial variables between obese and nonobese individuals with colon cancer.

This was a prospective, multicentric, observational study conducted from 2015-2018. The sample comprised patients with stage II-III, resected colon cancer about to initiate adjuvant chemotherapy with fluoropyrimidine in monotherapy or associated with oxaliplatin and grouped into nonobese (body mass index <30 kg/m

) or obese (≥30 kg/m

). Subjects completed questionnaires appraising quality of life (European Organization for Research and Treatment of Cancer Quality of Life Core questionnaire), coping (Mini-Mental Adjustment to Cancer), psychological distress (Brief Symptom Inventory 18), perceived social support (Multidimensional Scale of Perceived Social Support), personality (Big Five Inventory 10), and pain (Brief Pain Inventory).
