3 months versus 26.1 months, p = 0.005). Survival in patients with Child-Pugh A at 1, 3, and 5 years was 97%, 80%, and 73%, respectively, compared to 74%, 41%, and 31% in patients with Child-Pugh B/C. CONCLUSIONS In a small single-center cohort, patients with HCC who were denied liver transplant due to non-tumor reasons and underwent LRT and had Child-Pugh A cirrhosis had survival approaching the national average for patients who undergo liver transplantation. Patients with Child-Pugh B/C cirrhosis had significantly worse outcomes than those with Child-Pugh A.BACKGROUND Previous studies have shown vitamin D status to be associated with disease activity in patients with inflammatory bowel disease (IBD), but its influence on the clinical course of IBD has not been established. AIMS We aimed to analyze whether the serum 25-hydroxyvitamin D3 [25(OH)D] status is associated with clinical characteristics and affects the risk of surgery in patients with IBD. METHODS From the IBD registry of the Asan Medical Center, we identified all patients who had at least one 25(OH)D measurement; we then analyzed the association between clinical factors and 25(OH)D status. 25(OH)D was considered borderline deficient, deficient, and severely deficient at levels of less then  30, less then  20, and less then  10 ng/mL, respectively. RESULTS We included 711 Crohn's disease (CD) and 764 ulcerative colitis (UC) patients who had not undergone surgery before 25(OH)D was measured. Both in CD and in UC patients, reduced 25(OH)D was associated with higher disease activity scores and CRP levels (p  less then  0.001). Severe 25(OH)D deficiency was associated with ileocolonic disease and complicated behavior in CD (p  less then  0.05) and was relevant to the disease extent in UC (p  less then  0.001). Additionally, severe 25(OH)D deficiency was associated with CMV colitis in patients with UC (p  less then  0.001). In multivariable analysis, severe deficiency of 25(OH)D was an independent risk factor for surgery in both CD (HR 1.93, 95% confidence interval [CI] 1.38-2.70) and UC (HR 2.77, 95% CI 1.14-6.74). CONCLUSION Severe 25(OH)D deficiency may be a marker of a more aggressive clinical course of IBD.Polymer materials encapsulating drugs have broad prospects for drug delivery. We evaluated the effectiveness of polyethylene glycol-poly (lactic-co-glycolic acid) (PLGA-PEG) encapsulation and release characteristics of PI3K/mTOR inhibitor NVP-BEZ235 (BEZ235). We proposed a strategy for targeting radiosensitization of liver cancer cells. The biocompatibility, cell interaction, and internalization of Glypican-3 (GPC3) antibody-modified, BEZ235-loaded PLGA-PEG nanoparticles (NP-BEZ235-Ab) in hepatoma cells in vitro were studied. Also, the cell killing effect of NP-BEZ235-Ab combined with γ-ray cell was evaluated. We used confocal microscopy to monitor nanoparticle-cell interactions and cellular uptake, conducted focus-formation experiments to analyze the synergistic biological effects of NP-BEZ235-Ab and priming, and studied synergy in liver cancer cells using molecular biological methods such as western blotting. We found that PLGA-PEG has good loading efficiency for BEZ235 and high selectivity to GPC3-positive HepG2 liver cancer cells, thus documenting that NP-BEZ235-Ab acts as a small-molecule drug delivery nanocarrier. At the nominal concentration, the NP-BEZ235-Ab nanoformulation synergistically kills liver cancer cells with significantly higher efficiency than does the free drug. Thus, NP-BEZ235-Ab is a potential radiosensitizer.BACKGROUND Little is known about the prognosis regarding shunt revision and mortality among hydrocephalus patients below 2 years of age. The aims of this study were to investigate (1) the cumulative risks of shunt revision (SR) and mortality and (2) the potential associations between prematurity, low weight for gestational age (LWGA), underlying aetiology, sex, age of the child at shunt placement, and the risk of SR. METHOD This was a purely register-based cohort study including all shunted hydrocephalic infants in Denmark 1996-2015. The cumulative risks of SR and mortality were estimated using the Aalen-Johansen and Kaplan-Meier estimators, respectively. read more A multivariable Cox-regression model was used to estimate hazard ratios (HRs) for SR according to the listed patient-related risk factors. RESULTS Among 374 shunted infantile hydrocephalus patients accounting for 1047 SRs, the 3-month and 1-year cumulative risks of SR were 36% and 50%, respectively. The overall 10-year cumulative mortality was 12%, and for non-tumour subgroups 7-16% (isolated hydrocephalus 7%). The 10-year cumulative mortality for children born with LWGA was 21%. Except for aetiology, we observed no strong overall associations between the investigated risk factors and the risk of SR but interaction analyses for aetiology showed that patients with Dandy-Walker malformation born with LWGA had a higher risk of SR compared to patients of similar aetiology with normal WGA (HR 2.47, 95% CI 1.39-4.40). CONCLUSIONS We found very high cumulative risks of SR and mortality among this youngest group of hydrocephalus patients, disregarding aetiology, but none of them were strongly related to the investigated risk factors.This study tested whether increases in recent and cumulative cannabis use were each associated with increases in internalizing problems from adolescence to young adulthood. Participants were boys from a community sample that was assessed annually from ~age 15-26 (N = 506). Boys reported on their cannabis use, depression symptoms, and anxiety/depression problems each year. Exposures were frequency of cannabis use in a given year (no use, less then weekly use, weekly or more frequent use) and cumulative prior years of weekly cannabis use. Outcomes were depression symptoms and anxiety/depression problems in a given year. Analyses examined within-person associations between changes in exposures and outcomes over time, which eliminated "fixed" (unchanging) individual differences as potential confounds. Analyses also accounted for time-varying factors as potential confounds (other substance use, externalizing problems, subclinical psychotic symptoms). Results showed that increases in recent cannabis use and cumulative prior years of weekly cannabis use were each associated with increases in depression symptoms and anxiety/depression problems.
