    Adjuvant sorafenib may further enhance the efficacy of transarterial radioembolization for the treatment of hepatocellular carcinoma.

    To evaluate the efficacy and safety of radioembolization plus sorafenib in hepatocellular carcinoma patients.

    With a literature search through October 2020, we identified 9 studies (632 patients). Primary outcome was overall survival. Results were expressed as pooled median, odds ratio, or hazard ratio and 95% confidence intervals.

    Pooled overall survival after radioembolization plus sorafenib was 10.79 months (95% confidence interval 9.19-12.39) and it was longer in Barcelona Clinic Liver Cancer (BCLC) B (14.47 months, 9.07-19.86) as compared to BCLC C patients (10.22 months, 7.53-12.9). No difference between combined therapy versus radioembolization alone was observed in terms of overall survival (hazard ratio 1.07, 0.89-1.30). Pooled median progression-free survival was 6.32 months (5.68-6.98), with 1-year progression-free survival pooled rate of 38.5% (12.7%-44.2%). No difference in progression-free survival (hazard ratio 0.94, 0.79-1.12) between the two treatments was observed. Pooled rate of severe adverse events was 48.9% (26.7%-71.2%), again with no difference between the two treatment regimens (odds ratio 1.52, 0.15-15.02).

    The association of sorafenib does not seem to prolong survival nor delay disease progression in patients treated with radioembolization.

    Little is known about the management of squamous cell carcinoma of the anal canal and its recurrence at a population level. The aim of this study was to draw a picture of management, recurrence and survival in squamous cell carcinoma of the anal canal.

    The 5-year probability of recurrences was estimated using the cumulative incidence function to consider competing risks of death. Net survival was estimated and a multivariate survival analysis was performed. The study was conducted using data of the Burgundy Digestive Cancer Registry. Overall, 273 squamous cell carcinomas of the anal canal registered between 1998 and 2014 were considered.

    Overall, 80% of patients were treated with curative intent. Of these, 61% received chemoradiotherapy, 35% received radiotherapy and 4% received abdominoperineal resection alone. After these treatments, for cure the 5-year cumulative recurrence rate was 27% overall; it was 20% after chemoradiotherapy and 38% after radiotherapy. Five-year net survival was 71% overall; it was 81% after chemoradiotherapy and 55% after radiotherapy.

    Chemoradiotherapy was highly effective in routine practice. We confirm that it is difficult to distinguish between persistent active disease and local inflammation due to radiotherapy. Squamous cell carcinoma of the anal canal recurrences remains a substantial problem, highlighting the interest of prolonged surveillance. Aggressive management of recurrences may be beneficial.

    The association between dysregulated innate immune responses seen in Kawasaki disease (KD) with predisposition to Kawasaki-like multisystem inflammatory syndrome in children (MIS-C) remains unclear. We aimed to compare the innate immunity transcriptome signature between COVID-19 and KD, and to analyze the interactions of these molecules with genes known to predispose to KD.

    Transcriptome datasets of COVID-19 and KD cohorts (E-MTAB-9357, GSE-63881, GSE-68004) were downloaded from ArrayExpress for innate immune response analyses. Network analysis was used to determine enriched pathways of interactions.

    Upregulations of IRAK4, IFI16, STING, STAT3, PYCARD, CASP1, IFNAR1 and CD14 genes were observed in blood cells of acute SARS-CoV-2 infections with moderate severity. In the same patient group, increased expressions of TLR2, TLR7, IRF3, and CD36 were also noted in blood drawn a few days after COVID-19 diagnosis. Elevated blood PYCARD level was associated with severe COVID-19 in adults. Similar gene expressiomight predict COVID-19 severity and potentially susceptibility to COVID-19 related MIS-C.

    The potential effects of ivacaftor during pregnancy and breastfeeding on the offspring are still unknown. This study aimed to investigate pre-/postnatal age-related entry into the brain and lungs and transfer of maternally administered drug by the placental and via the milk.

    In acute experiments Sprague Dawley rats at embryonic day (E) 19, postnatal days (P) 4, 9, 16, and adult were administered an intraperitoneal injection of ivacaftor (40 mg/kg) traced with ivacaftor. To determine tissue entry, plasma, cerebrospinal fluid (CSF), lungs and brains were collected, and radioactivity measured using liquid scintillation counting. For long term experiments pregnant dams were orally treated at 25 mg/kg/day for 7 days and pups collected at E19. For postnatal pups, dams received treatment for 7 or 14 days and pups were collected at P6, 9, 13 and 16. To estimate placental and milk transfer concentration of ivacaftor in pup & maternal plasma was determined by liquid chromatography-mass spectrometry.

    At all ages, entry of ivacaftor into lungs, following either acute or prolonged exposure, was much higher than into brain & CSF. Brain entry appeared higher at earlier ages. Transfer across the placenta and breast milk. was estimated to be around ~40% of maternal plasma.

    Fetal and postnatal rats were exposed to maternally administered ivacaftor via placental and milk transfer. Preferential entry in the lungs at all ages suggests the possibility that exposing CF babies to maternally administered ivacaftor could be beneficial for limiting progression of CF pathology in early development.
