Risk of venous thromboembolism in people with lung cancer: a cohort study using linked UK healthcare data

Background: Venous thromboembolism is a potentially preventable cause of death in people with lung cancer. Identification of those most at risk and high risk periods may provide the opportunity for better targeted intervention. Methods: We conducted a cohort study using the Clinical Practice Research Datalink linked to Hospital Episode Statistics and Cancer Registry data. Our cohort comprised 10,598 people with lung cancer diagnosed between 1997 and 2006 with follow-up continuing to the end of 2010. Cox regression analysis was performed to determine which demographic, tumour and treatment-related factors (time-varying effects of chemotherapy and surgery) independently affected VTE risk. We also determined the effect of a VTE diagnosis on the survival of people with lung cancer. Results: People with lung cancer had an overall VTE incidence of 39.2 per 1000 person years (95% confidence Interval (CI), 35.4-43.5), though rates varied depending on the patient group and treatment course. Independent factors associated with increased VTE risk were: metastatic disease (hazard ratio (HR)=1.9, CI 1.2, 3.0 vs. local disease); adenocarcinoma sub-type (HR =2.0, CI 1.5, 2.7, vs. squamous cell; chemotherapy administration, (HR=2.1, CI 1.4, 3.0 vs. outside chemotherapy courses); and diagnosis via emergency hospital admission (HR=1.7, CI 1.2-2.3 vs. other routes to diagnosis). Patients with VTE had an approximately 50% higher risk of mortality than those without VTE. Conclusions: People with lung cancer have especially high risk of VTE if they have advanced disease, adenocarcinoma, or are undergoing chemotherapy. Presence of VTE is an independent risk factor for death

Alfalfa and flax sprouts supplementation enriches the content of bioactive compounds and lowers the cholesterol in hen egg

Abstract The effect of dietary supplementation with flax and alfalfa sprouts (40 g/d) on bioactive compounds and cholesterol contents of hen's egg was examined. Thirty White Leghorn hens, 26 weeks of age, were fed, for 66 days, three diets that included control (standard diet – C), standard diet + alfalfa sprouts (A), and standard diet + flax sprouts (F). Productive performance of hens was recorded daily. The cholesterol content of plasma and yolk, and the presence of bioactive compounds in the egg, were also analysed. Supplementation of flax and alfalfa sprouts reduced plasma and egg cholesterol probably due to the synergy between different compounds of the sprouts (polyunsaturated fatty acids - PUFAs, lignans, isoflavones and sterols). Eggs from A and F groups also had higher contents of n-3 PUFA, vitamins (α-tocopherol, α-, γ-tocotrienol, retinol), carotenes (β-carotene, lutein, zeaxanthin) and phytoestrogens (daidzein, equol, isolariciresinol) than eggs from the C group

Capsid-like particles decorated with the SARS-CoV-2 receptor-binding domain elicit strong virus neutralization activity

The rapid development of a SARS-CoV-2 vaccine is a global priority. Here, we develop two capsid-like particle (CLP)-based vaccines displaying the receptor-binding domain (RBD) of the SARS-CoV-2 spike protein. RBD antigens are displayed on AP205 CLPs through a split-protein Tag/Catcher, ensuring unidirectional and high-density display of RBD. Both soluble recombinant RBD and RBD displayed on CLPs bind the ACE2 receptor with nanomolar affinity. Mice are vaccinated with soluble RBD or CLP-displayed RBD, formulated in Squalene-Water-Emulsion. The RBD-CLP vaccines induce higher levels of serum anti-spike antibodies than the soluble RBD vaccines. Remarkably, one injection with our lead RBD-CLP vaccine in mice elicits virus neutralization antibody titers comparable to those found in patients that had recovered from COVID-19. Following booster vaccinations, the virus neutralization titers exceed those measured after natural infection, at serum dilutions above 1:10,000. Thus, the RBD-CLP vaccine is a highly promising candidate for preventing COVID-19.Molecular basis of virus replication, viral pathogenesis and antiviral strategie
