Access to health insurance and curative interventions [surgery/liver-directed-therapy (LDT)] affects survival for early-stage hepatocellular carcinoma (HCC). The aim of this multi-institutional study of high-volume safety-net hospitals (SNHs) and their tertiary-academic-centers (AC) was to identify the impact of type/lack of insurance on survival disparities across hospitals, particularly SNHs whose mission is to minimize insurance related access-to-care barriers for vulnerable populations.

Early-stage HCC patients (2012-2014) from the US Safety-Net Collaborative were propensity-score matched by treatment at SNH/AC. Overall survival (OS) was the primary outcome. Multivariable Cox proportional-hazard analysis was performed accounting for sociodemographic/clinical parameters.

Among 925 patients, those with no insurance (NI) had decreased curative surgery, compared to those with government insurance (GI) and private insurance [PI, (PI-SNH60.5% vs. GI-SNH33.1% vs. NI-SNH13.6%, p < 0.001)], and decreased median OS (PI-SNH32.1 vs. GI-SNH22.8 vs. NI-SNH9.4 months, p = 0.002). On multivariable regression controlling for sociodemographic/clinical parameters, NI-SNH (HR2.5, 95% CI1.3-4.9, p = 0.007) was the only insurance type/hospital system combination with significantly worse OS.

NI-SNH patients received less curative treatment than other insurance/hospitals types suggesting that treatment barriers, beyond access-to-care, need to be identified and addressed to achieve survival equity in early-stage HCC for vulnerable populations (NI-SNH).

One of the key factors limiting 6NSL production was the availability of oxygen during both cell cultivation and biotransformation of NHEG to 6NSL. Based on G. oxydans/pBBR1-sldAB-pqqABCDE-tldD (G. oxydans/AB-PQQ), the Vitreoscilla hemoglobin (VHb) was heterologously expressed in G. oxydans to enhance oxygen transfer efficiency and improve 6NSL production. The recombinant G. oxydans/AB-PQQ-VHb displayed higher biomass and NHEG oxidation activity than the control stain. selleck products The transcription levels of respiratory chain-related enzyme genes in G. oxydans/AB-PQQ-VHb exhibited up-regulation, indicating that the presence of VHb promoted the respiration. The dissolved oxygen (DO) concentration for cell cultivation was optimized in a 5-L stirred bioreactor. At a DO concentration of 20%, the maximum volumetric oxidation activity of NHEG of G. oxydans/AB-PQQ-VHb in the stirred bioreactor reached 168.3 ± 3.2 U/L. Furthermore, the biotransformation of NHEG to 6NSL using G. oxydans/AB-PQQ-VHb was carried out under different oxygen tensions to investigate the effect of oxygen on 6NSL production. Finally, up to 87.5 ± 5.9 g/L 6NSL was accumulated in the reaction mixture within 16 h when the DO was controlled at 30%.An enzyme showing l-histidine oxidase (HisO) activity by the formation of hydrogen peroxide was newly purified from Achromobacter sp. TPU 5009. This enzyme was found to be a heterodimer of two proteins (molecular mass, 53.8 and 58.3 kDa), the partial determination of which indicated they are homologs of l-histidine ammonia-lyase (AchHAL) and urocanate hydratase (AchURO). The enzyme was stable in a pH range of 5.0-11.0, with >90% of the original activity maintained below 60°C at pH 7.0. To characterize AchHAL and AchURO, each of their genes was cloned and expressed in a heterologous expression system. Heterologous AchHAL catalyzed the elimination of the α-amino group of l-histidine to urocanate and ammonia, while heterologous AchURO catalyzed the hydration of urocanate to imidazolone propionate. Since imidazolone propionate is highly unstable in the presence of oxygen at neutral pH, it was immediately decomposed and hydrogen peroxide was non-enzymatically produced. Our results indicate that this natural enzyme showing apparent HisO activity is composed of AchHAL and AchURO, which formed hydrogen peroxide after the spontaneous decomposition of imidazolone propionate.Congenital microphthalmia is a rare phenotype characterized by eye growth retardation. Due to the lack of eyeball stimulation, children suffering from congenital microphthalmia always have bony orbital maldevelopment, which leads to facial asymmetry. In the present study, a structured light 3D scanning system was used as a novel method to measure the three-dimensional periorbital asymmetry in children with congenital microphthalmia. Children with unilateral congenital microphthalmia of 0-6 years old were enrolled in the present study. All participants underwent an ultrasound scan to measure the axial length, and accepted the structured light 3D scanning system for their periorbital appearance. The degree of periorbital asymmetry was evaluated using 17 facial landmarks within a three-dimensional cartesian coordinate system (the X-axis represented the horizontal direction, the Y-axis represented the vertical direction, and the Z-axis represented the sagittal direction). Paired student t-test and ANOVA were usedunderstand the periorbital deformities caused by congenital microphthalmia.

Penile prosthesis for erectile dysfunction in patients with spinal cord injury or multiple sclerosis is sometimes discussed after failure of drug or instrumental treatments (vacuum). The objective of this study was to evaluate the complications, evolution and patient satisfaction after the implantation of a penile prosthesis in the neurological patient.

Multi-center retrospective study of 27consecutive patients including 18spinal cord injured patients and 9patients with multiple sclerosis benefiting from the implantation of a penile prosthesis for erectile dysfunction purposes in two French centers between 2009and 2019. Post-implantation complications, evolution of the use of the prosthesis and global patient satisfaction were evaluated using the standardized questionnaire Erectile Dysfunction Inventory of Treatment Satisfaction (EDITS) during a telephone call between March and May 2020.

The average age of implantation was 46.4years (±12.74). The length of follow-up to date of call was 6.05years (±2.86).
