Nowadays, it is known that oxidative stress plays at least two roles within the cell, the generation of cellular damage and the involvement in several signaling pathways in its balanced normal state. So far, a substantial amount of time and effort has been expended in the search for a clear link between cardiovascular disease (CVD) and the effects of oxidative stress. Here, we present an overview of the different sources and types of reactive oxygen species in CVD, highlight the relationship between CVD and oxidative stress and discuss the most prominent molecules that play an important role in CVD pathophysiology...

INTRODUCTION: Patient/practitioner communication plays a major role in the acceptance of treatment. Since the Kouchner law in France, patients must be allowed to give their free and informed consent and to be made aware of all the available therapies given their situation. MATERIALS AND METHODS: Practitioners have nowadays access to a range of aids enabling them to present the treatments they envisage as thoroughly as possible, exposed by the author in this article...

The growing importance of three-dimensional radiotherapy treatment has been associated with the active presence of advanced computational workflows that can simulate conventional x-ray films from computed tomography (CT) volumetric data to create digitally reconstructed radiographs (DRR). These simulated x-ray images are used to continuously verify the patient alignment in image-guided therapies with 2D-3D image registration. The present DRR rendering pipelines are quite limited to handle huge imaging stacks generated by recent state-of-the-art CT imaging modalities...

In spot-scanning particle therapy, inverse treatment planning is usually limited to finding the optimal beam fluences given the beam trajectories and energies. We address the much more challenging problem of jointly optimizing the beam fluences, trajectories and energies. For this purpose, we design a simulated annealing algorithm with an exploration mechanism that balances the conflicting demands of a small mixing time at high temperatures and a reasonable acceptance rate at low temperatures. Numerical experiments substantiate the relevance of our approach and open new horizons to spot-scanning particle therapy...

Robotic devices are a promising and dynamic tool in the realm of post-stroke rehabilitation. Researchers are still investigating how the use of robots affects motor learning and what design characteristics best encourage recovery. We present a parallel-actuated, end-effector robot designed to provide spatial assistance for upper-limb therapy while exhibiting low impedance and high backdrivability. A gradient based optimization was performed to find an optimal design that accounted for force isotropy, mechanical advantage, workspace size, and counter-balancing...

Postural instability affects a large number of people and can compromise even simple activities of the daily routine. Therapies for balance training can strongly benefit from auxiliary devices specially designed for this purpose. In this paper, we present a system for balance training that uses the metaphor of a game, what contributes to the motivation and engagement of the patients during a treatment. Such approach is usually named exergame, in which input devices for posturographic assessment and a visual output perform the interaction with the subject...

Chronic pain and prescription opioid abuse are extremely prevalent in the United States and worldwide. The consequences of opioid misuse can be life-threatening with significant morbidity and mortality, exacting a heavy toll on patients, physicians, and society. The risk for misuse of prescribed opioids is much higher in patients with chronic pain, especially those with concurrent substance use and /or mental health disorders. Several reasons can account for the occurrence of opioid abuse and misuse, including self-medication, use for reward, compulsive use related to addiction, and diversion for profit...

Gaucher disease is caused by mutations in GBA1, which encodes the lysosomal enzyme glucocerebrosidase (GCase). GBA1 mutations drive extensive accumulation of glucosylceramide (GC) in multiple innate and adaptive immune cells in the spleen, liver, lung and bone marrow, often leading to chronic inflammation. The mechanisms that connect excess GC to tissue inflammation remain unknown. Here we show that activation of complement C5a and C5a receptor 1 (C5aR1) controls GC accumulation and the inflammatory response in experimental and clinical Gaucher disease...

In patients with mRCC options for second line therapies, following progression on anti-angiogenic agents, that demonstrate a survival advantage in clinical trials have been limited. Recently a number of agents have demonstrated efficacy in this setting. Here in we profile one such therapy, the combination of lenvatinib and everolimus, and discuss the expanded options for therapy available in this setting. Areas covered: In this review, we discuss current algorithms for treatment of mRCC in both the first-line and second-line setting...

REVIEW
Rawad Elias, Theodoros Karantanos, Elizabeth Sira, Kevan L Hartshorn
Immune checkpoint inhibitors (ICIs) are based on the understanding that there are multilayered checks and balances which can be manipulated to unleash already existing, but paralyzed, immune responses to cancer. These agents are safer and more efficacious than classic cytotoxic drugs making them a very attractive therapeutic option, especially in older adults. Current available data do not suggest significant age-associated differences in the clinical profile of ICIs. It must be noted, however, that there is still relatively little information on the use of ICIs in adults over 75years of age and aging is associated with a decline in the immune system or "immunosenescence" which theoretically can reduce the efficacy of these immune based therapies...

OBJECTIVE: A combination of desferrioxamine with either deferiprone (DFP) or deferasirox (DFX) for patients with β-thalassemia major who do not achieve negative iron balance with monotherapy has been studied widely. However, poor compliance resulting from the need for parentral administration of desferrioxamine and its cost necessicitates combining 2 oral chelators. METHODS: A prospective study was conducted in patients with transfusion-dependent β-thalassemia major in a tertiary care center over 2 years...

BACKGROUND: Treatment with estrogen in early menopausal women protects against development of hepatic steatosis and NAFLD but estrogen has undesirable side effects which negate its beneficial effects in pre- and post-menopausal women. Targeted therapies require better understanding of the target sites and mechanisms by which estrogen signaling exerts its protective effects in women. ERα is thought to be the primary mediator for estrogen signaling to protect against hepatic steatosis...

Cardiovascular mortality of hemodialysis patients remains a major problem. The prevalence and incidence of atrial fibrillation in this population are more important than in the general population. The indication of antivitamin K therapy (AVK) in this context of atrial fibrillation must be weighted against the increased risk of bleeding. Unfortunately, and contrary to the general population, an indication of anticoagulation based on embolic or hemorrhagic risk scores is not as clearly established in the hemodialysis population...

Inflammation is a defensive mechanism for pathogen clearance and maintaining tissue homeostasis. In the skeletal system, inflammation is closely associated with many bone disorders including fractures, nonunions, periprosthetic osteolysis (bone loss around orthopedic implants), and osteoporosis. Acute inflammation is a critical step for proper bone-healing and bone-remodeling processes. On the other hand, chronic inflammation with excessive proinflammatory cytokines disrupts the balance of skeletal homeostasis involving osteoblastic (bone formation) and osteoclastic (bone resorption) activities...
