We propose that applying newly developed quantitative molecular and neuroscience technologies will advance our understanding of the unique neurobiology of each disorder and enable the development of personalized therapy.The aim of this study was to estimate the incidence of COVID-19 disease in the French national population of dialysis patients, their course of illness and to identify the risk factors associated with mortality. Our study included all patients on dialysis recorded in the French REIN Registry in April 2020. Clinical characteristics at last follow-up and the evolution of COVID-19 illness severity over time were recorded for diagnosed cases (either suspicious clinical symptoms, characteristic signs on the chest scan or a positive reverse transcription polymerase chain reaction) for SARS-CoV-2. A total of 1,621 infected patients were reported on the REIN registry from March 16th, 2020 to May 4th, 2020. Of these, 344 died. The prevalence of COVID-19 patients varied from less than 1% to 10% between regions. The probability of being a case was higher in males, patients with diabetes, those in need of assistance for transfer or treated at a self-care unit. Dialysis at home was associated with a lower probability of being infected as was being a smoker, a former smoker, having an active malignancy, or peripheral vascular disease. Mortality in diagnosed cases (21%) was associated with the same causes as in the general population. Higher age, hypoalbuminemia and the presence of an ischemic heart disease were statistically independently associated with a higher risk of death. Being treated at a selfcare unit was associated with a lower risk. Thus, our study showed a relatively low frequency of COVID-19 among dialysis patients contrary to what might have been assumed.The combination of photothermal and photodynamic therapy (PTT/PDT) shows pronounced potential as a prominent therapeutic strategy for tumor treatment. click here However, the efficacy is limited by insufficient tumor-targeted delivery of PTT and PDT reagents and the hypoxic nature of the tumor microenvironment. To overcome these limitations, tumor acidity-responsive lipid membrane-enclosed perfluorooctyl bromide oil droplet nanoparticles (NPs) surface modified with N-acetyl histidine-modified D-α-tocopheryl polyethylene glycol 1000 succinate (PFOB@IMHNPs) were developed, capable of co-delivering oxygen, IR780 (a photothermal agent) and mTHPC (a photodynamic sensitizer) into tumors. Through self-sufficient oxygen transportation in combination with promotion of cellular uptake upon acid-triggered generation of surface positive charge, the PFOB@IMHNPs effectively delivered IR780 and mTHPC and produced singlet oxygen within hypoxic TRAMP-C1 cells following exposure to irradiation at 660 nm. This led to effective killing of hypoxic cancer cells in vitro. Importantly, when irradiation at 808 and 660 nm was carried out, PT/PD combination therapy utilizing PFOB@IMHNPs dramatically suppressed the growth of TRAMP-C1 tumors through effective tumor-targeted cargo delivery and relief of tumor hypoxia. Our results suggest the high potential of the PFOB@IMHNPs developed in this study in clinical application for cancer treatment.Intravitreal delivery of antibody-based therapeutics has revolutionized the treatment of intraocular vascular diseases involving the retina and choroid. Unfortunately, limited durability requires frequent retreatment placing an enormous burden on patients. We sought to solve this problem with a novel approach that uses an anchoring molecule characterized by two key molecular properties (1) non-covalent binding to an antibody-based therapeutic, and (2) retention in the vitreous cavity. As an initial proof-of-principle, we chose an anchoring molecule composed of agarose microbeads functionalized with an Fc-binding domain. Bevacizumab was chosen as the antibody-based therapeutic. In vitro experiments demonstrated that bevacizumab was maximally bound to this anchoring molecule within 1 h, and was competitively released upon exposure to either polyclonal human (p less then 0.0001) or rat (p = 0.0017) immunoglobulins. In silico modeling predicted prolonged intravitreal retention of an antibody-based therapeutic in the presence of this anchoring molecule, which was confirmed by in vivo experiments with this initial anchoring molecule in rats. This anchoring molecule increased the intraocular half-life of bevacizumab from 5.8 days to over 18 days and maintained therapeutic concentrations for over 80 days. Despite showing no evidence of direct cellular toxicity, this anchoring molecule collected in the anterior vitreous, partially obscuring retinal visualization and eliciting a mild chronic microglial/macrophage inflammatory response. These studies provide a plausible approach to the development of novel non-covalent methods of binding, retention, and release of antibody-based therapeutics in the vitreous.Single reactive oxygen species (ROS)-mediated therapy, photodynamic therapy (PDT) or chemodynamic therapy (CDT) is severely hindered in hypoxic solid tumor. Herein, to address the urgent challenge, a hypoxia-activated ROS burst liposome has been fabricated to achieve synergistic PDT/CDT that is initiated by the structural dissociation of poly(metronidazole) liposome in hypoxic tumor microenvironment (TME). The therapeutic enhancement of our ROS-blasting treatment is simultaneously regulated by external light-initiated PDT and endogenous iron oxide nanoclusters-triggered CDT, which is synergistically boosted and amplified by localized mild hyperthermia under 808/660 nm coirradiation. More importantly, in vitro and in vivo experiments demonstrate that electron-affinic poly(aminoimidazole) product from hypoxia-responsive transition of poly(metronidazole) polymers could efficiently enhance hypoxic cell apoptosis and induce solid tumor ablation. Thus, this work offers a potential hypoxia-activated ROS burst-PDT/CDT strategy with a superior antitumor efficacy, highlighting a promising clinical application.To cater to medication needs in the future healthcare system, we need to shift from the conventional system of drug delivery to modern molecular signature-based drug delivery systems. The current drug therapies are either less effective, ineffective, or produce numerous adverse reactions. One scientific principle or discipline cannot adequately address all the problems, so we need an innovative application of the current scientific principles. Here we are proposing a novel concept of nanoformulation based on pharmacogenomics and theranostics for personalized error-free and targeted therapeutic agent delivery. The addition of more knowledge about the human genome opens the new way to study disease-gene, gene-drug, and drug-effect interactions, which is the basis of future medicines. Pharmacogenomics provides information about the disease etiology, role in genes in disease pathophysiology, disease biomarkers, drug targets, drug effects, and the fate of drugs inside the body. Theranostics approach utilizes the above information in diagnosis, treatment, and monitoring of the disease on a real-time basis.
