BACKGROUND: Tiered formularies, in which patients pay copays or coinsurance out-of-pocket (OOP), are used to manage costs and encourage more efficient health care resource use. Formulary tiers are typically based on the cost of treatment rather than the medical appropriateness for the patient. Cost sharing may have unintended consequences on treatment adherence and health outcomes. Use of higher-cost, higher-tier medications can be due to a variety of factors, including unsuccessful treatment because of lack of efficacy or side effects, patient clinical or genetic characteristics, patient preferences to avoid potential side effects, or patient preferences based on the route of administration...

In recent years, polymeric microneedles (MNs) have attracted keen interests among researchers for their applicability in transdermal drug delivery and interstitial skin fluid (ISF) extraction. When design and characterize such devices, it is critical to monitor their real-time in vitro and in vivo performances to optimize the desired effects, yet most of the existing methods are incapable of such functions. To address this unmet need, we develop a real-time non-invasive imaging methodology by integrating iron oxide (Fe3O4) nanoparticles into polymeric MNs to enhance image contrast for micro-optical coherence tomography (µOCT) imaging...

Several pathogenetic studies have paved the way for a newer more rational therapeutic approach to non-infectious uveitis, and treatment of different forms of immune-driven uveitis has drastically evolved in recent years after the advent of biotechnological drugs. Tumor necrosis factor-α targeted therapies, the first-line recommended biologics in uveitis, have certainly led to remarkable results in patients with non-infectious uveitis. Nevertheless, the decision-making process turns out to be extremely difficult in anti-tumor necrosis factor or multidrug-resistant cases...

Toxic myopathies are a large group of disorders generated by surrounding agents and characterized by structural and/or functional disturbances of muscles. The most recurrent are those induced by commonly used medications. Illicit drugs, environmental toxins from animals, vegetables, or produced by micro-organisms as well as chemical products commonly used are significant causes of such disorders. The muscle toxicity results from multiple mechanisms at different biological levels. Many agents can induce myotoxicity through a direct mechanism in which statins, glucocorticoids and ethyl alcohol are the most representative...

Understanding epigenetic processes holds immense promise for medical applications. Advances in Machine Learning (ML) are critical to realize this promise. Previous studies used epigenetic data sets associated with the germline transmission of epigenetic transgenerational inheritance of disease and novel ML approaches to predict genome-wide locations of critical epimutations. A combination of Active Learning (ACL) and Imbalanced Class Learning (ICL) was used to address past problems with ML to develop a more efficient feature selection process and address the imbalance problem in all genomic data sets...

A type 1 diabetic male reports multiple instances when his blood glucose was dramatically elevated by the presence of microwave radiation from wireless technology and plummeted when the radiation exposure ended. In one instance, his body temperature elevated in addition to his blood glucose. Both remained elevated for nearly 48 h after exposure with the effect gradually decreasing. Possible mechanisms for microwave radiation elevating blood glucose include effects on glucose transport proteins and ion channels, insulin conformational changes and oxidative stress...

Precise detection of low-dose X- and γ-radiations remains a challenge and is particularly important for studying biological effects under low-dose ionizing radiation, safety control in medical radiation treatment, survey of environmental radiation background, and monitoring cosmic radiations. We report here a photoluminescent uranium organic framework, whose photoluminescence intensity can be accurately correlated with the exposure dose of X- or γ-radiations. This allows for precise and instant detection of ionizing radiations down to the level of 10(-4)  Gy, representing a significant improvement on the detection limit of approximately two orders of magnitude, compared to other chemical dosimeters reported up to now...

Perceiving abnormal regions in the images of different medical modalities plays a crucial role in diagnosis and subsequent treatment planning. In medical images to visually perceive abnormalities' extent and boundaries requires substantial experience. Consequently, manually drawn region of interest (ROI) to outline boundaries of abnormalities suffers from limitations of human perception leading to inter-observer variability. As an alternative to human drawn ROI, it is proposed the use of a computer-based segmentation algorithm to segment digital medical image data...
