ABSTRACT

INTRODUCTION: Impacts of health insurance status on survival outcomes among adolescent and young adult (AYA, 15 to 39 years of age) patients with lymphoma in the United States are insufficiently known. This study aimed to clarify associations between health insurance status and overall survival (OS) estimates in this population. MATERIALS AND METHODS: We examined 18 Surveillance, Epidemiology, and End Results registries in the United States and analyzed American AYA patients with lymphoma diagnosed during January 2007 and December 2016. Health insurance status was categorized, and Kaplan-Meier and multifactor Cox regressions were adopted using hazard ratio and 95% confidence interval. Probable baseline confounding was modulated by multiple propensity score. RESULTS: A total of 21,149 patients were considered; ~28% were 18 to 25 years old, and 63.5% and 7.5% had private and no insurance, respectively. Private insurance rates increased in the 18 to 25 age group (60.1% to 6.1%, P<0.001) following the 2010 Patient Protection and Affordable Care Act (ACA), and lymphoma survival rates improved slightly 1 to 5 years postdiagnosis. Five-year OS rates decreased with age (93.9%, 90.4%, and 87.0% at 15 to 17, 18 to 25, and 26 to 39, respectively) and differed among insurance conditions (81.7%, 79.2%, 89.2%, and 92.0% for uninsured, Medicaid, insured, and insured/no specifics, respectively). Risk of death was significantly higher for those with Medicaid or no insurance than for those with private insurance in multiple propensity score-adjusted models (hazard ratio [95% confidence interval]=1.07 [1.03-1.12]), independent of stage at diagnosis. CONCLUSIONS: No or insufficient insurance was linked to poor OS in our sample in exposure-outcome association analysis. Insurance coverage and health care availability may enhance disparate outcomes of AYAs with cancer. The ACA has improved insurance coverage and survival rates for out sample. Nevertheless, strategies are needed to identify causality and eliminate disparities.

ABSTRACT

INTRODUCTION: The impact of health insurance status on the survival outcomes of patients with locally advanced gastric cancer (LAGC) receiving gastrectomy have not been addressed in depth. We aim to identify definite associations of health insurance status with cancer-specific survival (CSS) and overall survival (OS) in this population. METHODS: We identified LAGC patients aged 18 to 64 years undergoing gastrectomy with complete insurance records, between January 1, 2007, and December 31, 2016, from 18 Surveillance, Epidemiology, and End Results database registries. Relationships between health insurance status and OS/CSS were explored by Kaplan-Meier time-to-event analysis and uni-/multi-variate Cox regression. Probable baseline confounder was adjusted by multiple propensity score (mPS)-adjusted analysis. RESULTS: In total, 5,860 patients met the inclusion criteria. In the multivariate Cox regression, Medicaid coverage was related to poorer OS than private insurance. Non-insurance or Medicaid coverage versus private insurance tended to present poorer OS in the mPS-adjusted model, but this result was insignificant for CSS. CONCLUSIONS: Our observational study of exposure-outcome associations suggests that limited or no insurance is moderately linked with OS among LAGC patients undergoing gastrectomy and aged 18-64 years. Healthcare accessibility and broad insurance coverage probably strengthen some disparity outcomes.

ABSTRACT

BACKGROUND: The impacts of health insurance status on survival outcomes in children, adolescents, and young adults (aged 0-39 years) with malignant tumors have not been addressed in depth. The present study aimed to identify significant relationships of health insurance condition with overall survival or all-cause mortality among children (age 0-14 years) and adolescents and young adults (AYAs, age 15-39 years) with malignant tumors. METHODS: PubMed, Wiley Cochrane Central Register of Controlled Trials, Econlit, CINAHL, Web of Knowledge, PsychInfo, Business Source Premier, ProQuest Dissertation & Theses Database, and SCOPUS were systematically searched from inception to February 29, 2020 with no language restriction. All related articles comparing the effect of health insurance status on the risk of overall survival and the risk of all-cause mortality in malignant conditions affecting children and AYAs were identified. Pooled risk ratios (RRs) and 95% confidence intervals (CIs) were computed using a random- or fixed-effect model as per the heterogeneity evaluated using Cochran`s Q and I < sup > 2 < /sup > statistics. RESULTS: Fourteen studies including 149,680 individuals were selected for this meta-analysis. The pooled RR for all-cause mortality with insurance versus without insurance was 0.78 (95%CI, 0.71-0.86; I2=33.7%). Among the insurance types, patients with private insurance presented with a lower all-cause mortality (RR 0.70, 95% CI 0.60-0.82), with considerable heterogeneity (I2=83.3%). CONCLUSIONS: The findings of this review suggest that a lack of or insufficient insurance is related to all-cause mortality of AYAs with malignant cancers. Strategies aimed at identifying causality and reducing disparities are warranted.

ABSTRACT

ß-Glucan from Saccharomyces cerevisiae has been described to be effective antioxidants, but the specific antioxidation mechanism of ß-glucan is unclear. The objectives of this research were to determine whether the ß-glucan from Saccharomyces cerevisiae could regulate oxidative stress through the Dectin-1/Nrf2/HO-1 signaling pathway in lipopolysaccharides (LPS)-stimulated RAW264.7 cells. In this study, we examined the effects of ß-glucan on the enzyme activity or production of oxidative stress indicators in LPS-stimulated RAW264.7 cells by biochemical analysis and the protein expression of key factors of Dectin-1/Nrf2/HO-1 signaling pathway by immunofluorescence and western blot. The biochemical analysis results showed that ß-glucan increased the LPS-induced downregulation of enzyme activity of intracellular heme oxygenase (HO), superoxide dismutase (SOD), catalase (CAT), and glutathione peroxidase (GSH-Px) while decreasing the production of reactive oxygen species (ROS) and malondialdehyde (MDA). Furthermore, immunofluorescence results showed that ß-glucan can activate the nuclear factor erythroid 2-related factor 2 (Nrf2). The antioxidant mechanism study indicated that ß-glucan activated dendritic-cell-associated C-type lectin 1 (Dectin-1) receptors mediated Nrf2/HO-1 signaling pathway, thereby downregulating the production of ROS and thus produced the antioxidant effects in LPS-stimulated RAW 264.7 cells. In conclusion, these results indicate that ß-glucan potently alleviated oxidative stress via Dectin-1/Nrf2/HO-1 in LPS-stimulated RAW 264.7 cells.

ABSTRACT

Yeast autolysis under solid-state fermentation can effectively promote the release of various active substances, thereby improving the quality of yeast products. The optimal process for yeast autolysis under solid-state fermentation was obtained by optimizing the autolysis temperature, autolysis time and the zinc ion concentration. We analyzed the indexes of free amino acid, soluble protein and α-amino nitrogen in the fermentation material, as well as A260/A280 ratio to determine yeast autolysis process conditions in the solid-state fermentation. On the basis of the obtained data, L9 (3³) orthogonal test was designed to optimize the solid-state fermentation parameters for yeast autolysis: temperature at 40, 50 and 55 °C; time 12, 18 and 24 h; zinc ion concentration 2, 4 and 8 mg/kg. The optimum process conditions for yeast autolysis were: autolysis temperature 55 °C, time 18 h, zinc ion concentration 2 mg/kg, and soluble protein content reached 9.31 mg/g, free amino acid 14.36 mg/g, α-amino nitrogen 10.16 µg/g and A260/A280 1.73. After optimization of the process, the soluble protein, free amino acid and α-amino nitrogen contents of the yeast autolysis production can be significantly increased, thereby obviously improving the quality of the composite culture.

ABSTRACT

Solid tumors following myelodysplastic syndrome (MDS) are rare and have no uniform treatment guidelines. The current study presents a rare case of a 47-year-old female diagnosed with cervical cancer (International Federation of Gynecology and Obstetrics stage IIIB) with an eight-year history of MDS. A multidisciplinary treatment discussion was organized and a rigorous treatment plan was developed. With injection of granulocyte colony-stimulating factor and interleukin-11 factor, transfusion of red blood cell suspension and close monitoring of the blood count, the patient was administered radiotherapy, specifically intensity modulated radiation therapy. However, a degree IV bone marrow suppression repeatedly assaulted, leading to interruption of the radiotherapy treatment. Eventually, the total dose received by point A (2 cm above the cervical os marker and 2 cm perpendicular to the uterine axis along the plane of the uterus) was 51 Gy. One month later, a gynecological examination and magnetic resonance imaging of the pelvis revealed that the treatment resulted in a complete remission. In conclusion, radiation therapy can still be implemented to obtain satisfactory local control when the hematopoietic function of the bone marrow is weakened due to long-term MDS.
