GLAUCOMA AND ALZHEIMER’S DISEASE

Bentham Science observes World Glaucoma Week from 8th to 15th March, 2018, with the world and presents full support for the victims of glaucoma through publishing the latest research developments to combat this dangerous eye disease. Glaucoma is a widely feared eye problem because it causes irreversible blindness. Eye researchers and ophthalmologists have mostly attributed glaucoma to the increase in intraocular pressure, i.e. the increase in fluid pressure inside the eye.

However there are cases where the glaucoma patients had normal intraocular pressure, which suggests that there are other factors that can cause or enhance the risk of contracting this disease. Researchers from the Ophthalmology Unit of the University of Rome Tor Vergata have recently discovered that the patients of Alzheimer’s were often found susceptible of getting glaucoma in their eyes. Alzheimer’s disease is the most common form of dementia in the elderly that hampers memory and understanding.

Both these neurodegenerative diseases were found to have very similar risk factors and often co-existed in the older people. The research is an important revelation and opens doors for future studies and possible progress in finding cure for both Alzheimer’s disease and glaucoma.

The research entitled, Glaucoma and Alzheimer Disease: One Age-Related Neurodegenerative Disease of the Brain, is published in the Bentham Science journal, Current Neuropharmacology.

MOST ACCESSED ARTICLE – Diagnostic Imaging of Hepatocellular Carcinoma – Current Medical Imaging Reviews

Journal: Current Medical Imaging Reviews

Author(s): Tomasz K. Nowicki*, Karolina Markiet, Edyta Szurowska

Graphical Abstract:

 

Abstract:

Hepatocellular carcinoma (HCC) is the most common primary liver cancer, which develops mostly in the setting of chronic liver disease. European Association for the Study of the Liver (EASL) and European Organization for Research and Treatment of Cancer (EORTC) prepared guidelines for screening, follow-up and diagnosis of HCC to facilitate decision making and optimize both diagnostic and therapeutic protocols.

 

The review briefly describes etiology, epidemiology and histopathology of HCC and presents EASL-EORTC guidelines for surveillance and diagnosis of HCC. Target population and screening algorithm is presented in the surveillance section. Ultrasound imaging of HCC and the role of contrast enhanced ultrasound are described as well as the value of laboratory tests in screening. Further, radiological features of HCC in multiphase CT and dynamic contrast enhanced MRI and diagnostic criteria are presented. Additionally, the advantages of advanced techniques in MRI such as diffusion weighed imaging and the use of hepatocyte-specific contrast agents are discussed.

Lastly, the EASL-EORTC guidelines are compared with the guidelines of the American Association for the Study of Liver Diseases and the Japan Society of Hepatology. Also LI-RADS and the Barcelona Clinic Liver Cancer classification are mentioned.
In the near future, due to the ongoing advances in imaging a revision of the guidelines may be expected.

 

Brand New Issue: Inflammation & Allergy-Drug Targets

  • Inflammaging in Skin and Other Tissues – The Roles of Complement System and Macrophage
Author(s): Yong Zhuang and John Lyga
Pages 153-161 (9)
Abstract:

Inflammaging refers to a continuous, low-grade inflammation associated with aging. Such chronic inflammatory response could build up with time and gradually causes tissue damage. It is considered as one of the driving forces for many age-related diseases such as diabetes, atherosclerosis, age-related macular degeneration (AMD), and skin aging. There is mounting evidence that indicates aging is driven by the pro-inflammatory cytokines and substances produced by our body’s innate immune system. The macrophage and complement system, two important components of innate immune system, have attracted more and more attention since they appear to be involved in the pathogenesis of several inflammaging-associated diseases, such as AMD and atherosclerosis. This paper will review what we know about these two innate immune systems in the pathogenesis of AMD, atherosclerosis and skin aging.

  • Acne Vulgaris: an Inflammatory Disease Even Before the Onset of Clinical Lesions
Author(s): Marco Alexandre Rocha, Caroline Sousa Costa and Edileia Bagatin
Pages 162-167 (6)
Abstract:

Acne is a chronic self-limited disease, which affects mostly teenagers, without gender difference. In recent years, the incidence has increased in female adults. The factors involved in this epidemiological observation are still under discussion in the literature.Clinically, acne is characterized by different types of lesions. The disease affects the regions rich in sebaceous glands (face, chest and upper back). The clinical lesions are: open and closed comedones, erythematous papules, pustules, nodules and different types of scars. Taking into consideration the general concept of inflammation (redness, pain, heat and loss of function), acne is traditionally classified as non-inflammatory (open and closed comedones) and inflammatory (other primary lesions). With the knowledge advancement this concept seems to be wrong and therefore acne would be an inflammatory disease even before the onset of their clinical lesions.

  • Effect of Botanicals on Inflammation and Skin Aging: Analyzing the Evidence
Author(s): Amanda Suggs, Patricia Oyetakin-White and Elma D. Baron
Pages 168-176 (9)
Abstract:

The skin and its immune system manifest a decline in physiologic function as it undergoes aging. External insults such as ultraviolet light exposure cause inflammation, which may enhance skin aging even further leading to cancer and signs of photoaging. There is a potential role for botanicals as an adjunct modality in the prevention of skin aging. Numerous over-the-counter anti-aging products are commercially available, many of which boast unverified claims to reduce stress, inflammation and correct signs of aging. In this article we reviewed the scientific literature for data on frequently published “anti-inflammaging” additives such as vitamins A, C and E and green tea. We also analyzed the evidence available on five promising ingredients commonly found in anti-aging products, namely, argan oil, rosemary, pomegranate, Coenzyme Q10, and Coffeeberry. Though there may be an increasing amount of scientific data on a few of these novel botanicals, in general, there remains a lack of clinical data to support the anti-aging claims made.

  • Brain-Skin Connection: Stress, Inflammation and Skin Aging
Author(s): Ying Chen and John Lyga
Pages 177-190 (14)
Abstract:

The intricate relationship between stress and skin conditions has been documented since ancient times. Recent clinical observations also link psychological stress to the onset or aggravation of multiple skin diseases. However, the exact underlying mechanisms have only been studied and partially revealed in the past 20 years or so. In this review, the authors will discuss the recent discoveries in the field of “Brain-Skin Connection”, summarizing findings from the overlapping fields of psychology, endocrinology, skin neurobiology, skin inflammation, immunology, and pharmacology.

  • Biological Treatments for SAPHO Syndrome: An Update
Author(s): Davide Firinu, Giuseppe Murgia, Maria Maddalena Lorrai, Maria Pina Barca, Maria Monica Peralta, Paolo Emilio Manconi and Stefano R. del Giacco
Pages 199-205 (7)
Abstract:

Synovitis, Acne, Pustulosis, Hyperostosis and Osteitis (SAPHO) syndrome is a rare and often unrecognized disease with prominent inflammatory cutaneous and articular manifestations. Since the identification of the syndrome many immunosuppressive drugs have been used for the management of SAPHO, with variable results. The use of anti- TNF-α agents as a therapeutic option for SAPHO cases unresponsive or refractory to conventional drugs, demonstrated their efficacy for bone, skin and joints manifestations. TNF-α is a pro-inflammatory cytokine and pivotal regulator of other cytokines, including IL-1 β , IL-6 and IL-8, involved in inflammation, acute-phase response induction and chemotaxis. IL-1 inhibition strategies with Anakinra have proven their efficacy as first and second line treatment. We herein review the literature concerning the use of biological drugs in patients with SAPHO syndrome. In addition, we describe for the first time the use of Ustekinumab, an antibody against the p40 subunit of IL-12 and IL-23, after failure of multiple drugs including anti-TNF-α and Anakinra. This anti-IL12/IL23 agent could be a promising therapeutic option, also considering the opportunity to interfere with the IL23/TH17 pathway, which we recently found disturbed. Furthermore, a rationale emerges for the use of the new anti-IL-1 antagonists or the IL-17 blockade, in particular for the most difficult-to-treat SAPHO cases.

  • Cardiac and Muscular Involvement in Idiopathic Inflammatory Myopathies: Noninvasive Diagnostic Assessment and the Role of Cardiovascular and Skeletal Magnetic Resonance Imaging
Author(s): Sophie Mavrogeni, Petros P. Sfikakis, Theodoros Dimitroulas, Genovefa Kolovou and George D. Kitas
Pages 206-216 (11)
Abstract:

Idiopathic inflammatory myopathies (IIMs) are rare autoimmune diseases and include dermatomyositis, polymyositis, necrotizing myopathy and inclusion body myositis; they are characterized by inflammation of skeletal muscle and other internal organs and may potentially lead to irreversible damage and death. Only a small percentage of IIM has clinically overt cardiac disease; however, heart involvement is one of the leading causes of death and therefore, early detection remains a challenge.Biochemical markers and non-invasive methods such as the electrocardiogram and echocardiography have a role in diagnosis, but lack sensitivity in identifying patients with early, sublinical cardiac abnormalities. Endomyocardial and skeletal muscle biopsies are very useful, but invasive techniques and cannot be used for routine follow-up. Cardiac and skeletal magnetic resonance imaging, due to their capability to perform tissue characterization, has emerged as novel techniques for the early detection and follow-up of myocardial and skeletal muscle tissue changes (oedema, inflammation, fibrosis) in IIM. However, the clinical implications of using these approaches and their cost /benefit ratio require further evaluation.
