The AIC value from the four significant parameters was lowest for the Weibull-exponential distribution (222.3) than that of the Cox (653.7) and standardized exponential models (265.7). We developed a model for estimating the 1-year survival probability using the Weibull-exponential distribution.

Low-skeletal muscle index, PS, requirement of biliary drainage, CEA levels, and presence of ascites are independent factors for predicting poor patient survival after chemotherapy. Improved survival modeling using a parametric approach may accurately predict the outcome of patients with advanced-stage PDA.

GR43175 Decades of observational and clinical trials have demonstrated that midlife hypertension is associated with greater gray matter atrophy, white matter damage commiserate with demyelination, and functional deficits as compared to normotension over the adult lifespan. Critically, hypertension is a modifiable dementia risk factor successful blood pressure control with antihypertensive treatment improves outcomes as compared to uncontrolled hypertension, but does not completely negate the risk for dementia. This suggests that hypertension-related risk for neural and cognitive decline in aging cannot be due to elevations in blood pressure alone. This summary review describes three putative pathways for hypertension-related dementia risk oxidative damage and metabolic dysfunction; systemic inflammation; and autonomic control of heart rate variability. The same processes contribute to pre-clinical hypertension, and therefore hypertension may be an early symptom of an aging nervous system that then exacerbates cumulative and progressive neurodegeneration. Current evidence is reviewed and future directions for research are outlined, including blood biomarkers and novel neuroimaging methods that may be sensitive to test the specific hypotheses.

To evaluate whether pentosan polysulfate maculopathy manifests distinctive imaging features that can be differentiated from those found in age-related macular degeneration (AMD).

Local databases were queried to identify patients with a diagnosis of interstitial cystitis who were seen at the Emory Eye Center between May 2014 and January 2019 and who had fundus imaging available for review. Ninety patients met the eligibility criteria. Masked graders categorized patients based on imaging characteristics as follows category 1 pentosan polysulfate maculopathy; category 2 AMD or drusen; category 3 neither; and category 4 unsure. Pentosan polysulfate exposure characteristics were compared among groups.

Of the 90 subjects evaluated, 79 (88%) were female and the median age was 61.5 years (range, 30-89). Seventeen patients were placed in category 1; 25 in category 2; 47 in category 3, and; 1 in category 4. Among categories 1 to 4, respectively, 17 (100%), 15 (60%), 28 (60%), and 0 patients had exposure to pentosan polysulfate (p = 0.007). Mean cumulative exposure to pentosan polysulfate across the four categories was 2.1, 0.36, 0.34, and 0 kg, respectively (p < 0.00001). Eyes with pentosan polysulfate maculopathy did not have typical drusen in the macula.

Although pentosan polysulfate maculopathy resembles some aspects of AMD, the two conditions can be differentiated with the use of multimodal fundus imaging.

Increasing studies have shown a vital fact that long non-coding RNAs (lncRNAs) play a considerable regulatory role in hepatocellular carcinoma (HCC) progression. However, whether ST8 alpha-N-acetyl-neuraminide alpha-2, 8-sialyltransferase 6 antisense RNA 1 (ST8SIA6-AS1) affects the development of HCC is unclear.

The target genes in HCC cell lines were quantified via utilzing quantitative real-time polymerase chain reaction (RT-qPCR) analysis and western blot. Effects of ST8SIA6-AS1 on proliferative, apoptosis and migratory ability of HCC cells were proved by a series of function experiments. The cellular distribution of ST8SIA6-AS1 was examined through fluorescent in situ hybridization (FISH) assay and subcellular fractionation experiments. RNA pulldown assay was implemented to explore the target of ST8SIA6-AS1. RNA Binding Protein Immunoprecipitation (RIP) and luciferase reporter assays were performed to identify the specific relationships between miR-338-3p and ST8SIA6-AS1/ non-POU domain containing octamer binding (NONO).

The expression of ST8SIA6-AS1 was apparently elevated in HCC cell. Silenced ST8SIA6-AS1 reduced proliferative, migratory and invasive ability of HCC cells. Moreover, ST8SIA6-AS1 targeted miR-338-3p to modulate the expression of NONO in HCC cells.

ST8SIA6-AS1 enhances the progression of HCC via miR-338-3p/NONO axis in vitro.

The efficacy of anti-programmed death receptor 1 (PD-1) therapy in patients with large cell neuroendocrine carcinoma (LCNEC) remains unclear. We investigated the outcome of anti-PD-1 therapy and its predictive markers by evaluating the immune-related tumor microenvironment.

We retrospectively reviewed patients with advanced LCNEC treated with systemic chemotherapy. We also evaluated PD ligand 1 (PD-L1) expression (clone 22C3), CD8-positive tumor-infiltrating lymphocytes (TILs), and the mutational profiles.

Seventy patients were enrolled, and 13 of 70 patients received anti-PD-1 therapy. The progression-free survival (PFS) and objective response rate (ORR) of the anti-PD-1 therapy were 4.2 months and 39%, respectively. The overall survival of patients treated with anti-PD-1 therapy (n=13) was significantly better than those treated without anti-PD-1 therapy (n=57) (25.2 months vs 10.9 months; P=.02). Among the 13 patients treated with anti-PD-1 therapy, 10 patients (90%) had PD-L1-negative tumors. Patients with a high density of tumoral CD8-positive TILs (≥38/mm

) had a significantly better ORR and PFS than those with a low density of tumoral CD8-positive TILs (ORR P=.
