Published by Elsevier Ltd.BACKGROUND Recent publications have suggested an increased risk of delayed adverse events (DAE) with a smooth, cohesive 20 mg/mL hyaluronic acid filler (HA-V). OBJECTIVE To examine the occurrence of HA-V DAEs and identify patterns and characteristics. METHODS Charts from patients who received HA-V between February 1, 2009 and February 28, 2018 from two clinics were analyzed. RESULTS In 4500 patients who received 9324 treatments with HA-V, 44 DAE's were identified, for a combined incidence of 0.98% per patient, 0.47% per treatment, and 0.23% per syringe. Patients with DAEs received a slightly larger cumulative amount of HA-V than those who did not. Delayed swelling and nodule formation were the most common reactions and occurred a median of 4 months after treatment, with an increase in frequency between October and January. About a third were preceded by an identifiable immunologic stimulus. DAEs were transient and resolved without incident. LIMITATIONS Retrospective nature made it difficult to capture time to resolution or remember potential triggers. CONCLUSION In this large, long-term retrospective review, HA-V DAEs occurred at a rate of 0.98% per patient. Although the exact cause has yet to be elucidated, the authors hypothesize an increase in fragmentation during the HA-V degradation process may trigger an inflammatory response following an immunologic trigger. There has been rapid growth in teledermatology over the past decade and teledermatology services are increasingly being utilized to support patient care across a variety of care settings. Teledermatology has the potential to increase access to high quality dermatologic care while maintaining clinical efficacy and cost-effectiveness. Recent expansions in telemedicine reimbursement from the Centers for Medicare & Medicaid Services (CMS) ensure that teledermatology will play an increasingly prominent role in patient care. Therefore, it is important that dermatologists are well-informed of both the promises of teledermatology and the potential practice challenges a continuously evolving mode of care delivery brings. In this article, we will review the evidence on the clinical and cost-effectiveness of teledermatology and we will discuss system-level and practice-level barriers to successful teledermatology implementation as well as potential implications for dermatologists. selleck chemicals Peste des petits ruminants (PPR) is a highly contagious and fatal disease of small ruminants, particularly sheep and goats. This disease leads to high morbidity and mortality of small ruminants, thus resulting in devastating economic loss to the livestock industry globally. The severe disease impact has prompted the Food and Agriculture Organization of the United Nations (FAO) and the World Organization for Animal Health (OIE) to develop a global strategy for the control and eradication of PPR by 2030. Over the past decades, the control of PPR is mainly achieved through vaccinating the animals with live-attenuated vaccines, e.g., rinderpest vaccines. As a closely related disease to PPR of large ruminants, rinderpest was eradicated in 2011 and its vaccines subsequently got banned in order to keep rinderpest-free zones. Consequently, it is desirable to develop homologous PPR vaccines to control the disease. The present review summarizes the objectives of PPR control and eradication by focusing on the homologous PPR vaccines. The emergence and spread of antibiotic-resistant bacteria constitute a critical issue for modern medicine. Patients with antibiotic-resistant bacterial infections consume more healthcare resources and have worse clinical outcomes than patients with antibiotic-sensitive bacterial infections. Phages are natural predators of bacteria and may therefore be a source of useful antibacterial drugs. Phage therapy possess availability for oral administration, penetration through the bacteria cell wall, and eradication bacterial biofilms. All of these advantages give phage therapy the possibility to turn into applications for infectious diseases. In this mini-review, we focus on the brief history of lytic phage therapy, the life cycles of lytic phages and the therapeutic effects of lytic phages. Carcinogenesis is a complex multistep process, characterized by changes at different levels, both genetic and epigenetic, which alter cell metabolism. Positron emission tomography (PET) is a very sensitive image modality that allows to evaluate oncometabolism. PET functionalities are immense, since by labelling a molecule that specifically intervenes in a biochemical regulatory pathway of interest with a positron-emitting radionuclide, we can easily image that pathway. Thus, PET makes possible imaging several metabolic processes and assessing risk prediction, screening, diagnosis, response to therapy, metastization and recurrence. In this paper, we provide an overview of different radiopharmaceuticals developed for PET use in oncology, with a focus on brain tumours, breast cancer, hepatocellular carcinoma, neuroendocrine tumours, bladder cancer and prostate cancer because for these cancer types PET has been shown to be valuable. Most of the described tracers are just used in the research environment, with the aim to assess if these tracers could be able to offer an improvement concerning staging/restaging, characterization and stratification of different types of cancer, as well as therapeutic response assessment. In pursuit of personalized therapy, we briefly discuss the more established metabolic tracers and describe recent work on the development of new radiopharmaceuticals, aware that there will continue to exist diagnostic challenges to face modern cancer medicine. Cancer proliferation and progression involves altered metabolic pathways as a result of continuous demand for energy and nutrients. In the last years, cell cycle regulators have been involved in the control of metabolic processes, such as glucose and insulin pathways and lipid synthesis, in addition to their canonical function controlling cell cycle progression. Here we describe recent data demonstrating the role of cell cycle regulators in the metabolic control especially in studies performed in cancer models. Moreover, we discuss the importance of these findings in the context of current cancer therapies to provide an overview of the relevance of targeting metabolism using inhibitors of the cell cycle regulation.
