OBJECTIVE To explore the various types and phases of clinical trials, the regulatory oversight, drug approval process, and implications of clinical trials for the oncology nurse. DATA SOURCES Peer-reviewed journal articles, internet, book chapters, white papers. CONCLUSION Oncology nurses' interactions with patients entered on clinical trial and communication with the clinical research team is crucial to the successful conduct of clinical trials. The oncology nurse must work in concert with the clinical research team to protect patient safety and to produce accurate information for protocol requirements that will be used to evaluate whether a drug becomes approved or not by the US Food and Drug Administration. IMPLICATIONS FOR NURSING PRACTICE Oncology nurses play a central role to the successful outcome of clinical research studies. Nurses must work in close collaboration with the clinical research teams for the successful completion and adherence of the clinical trial and to maintain the safety of the patient enrolled into clinical trial. OBJECTIVES This article will provide an overview of the purpose, structure, and function of an investigational pharmacy in oncology clinical research. It will also discuss the role of the oncology nurse in managing investigational drugs (ID) when caring for a patient receiving treatment on a clinical trial and the importance of their role in the trial process. DATA SOURCES Government regulations, professional guidelines, and best practices. CONCLUSION ID management for clinical trials is a multidisciplinary process requiring input from various professionals to ensure safe, accurate, and study-specific administration. The nurse's role in the process of clinical trial ID management is dependent on each institution's expectations of clinical research nurses and the scope of their role. IMPLICATIONS FOR NURSING PRACTICE Multiple nursing roles may be involved in caring for patients who are being treated as part of a clinical trial, including clinical research nurses, infusion nurses, or as nurses providing direct patient care (inpatient or outpatient). Providing education on ID management, specific to the nurse's involvement, is a responsibility of the study team. Ensuring proper safeguards, accurate and protocol-specific delivery and documentation of ID, and completion of patient education are key in the conduct of oncology clinical research. OBJECTIVES To explore the federal regulations governing clinical trials and human subject protection, the importance of research participant's informed consent, and the role the oncology clinical research nurse has within the clinical trial setting. DATA SOURCES Peer-reviewed journal articles, internet, book chapters, white papers. CONCLUSION Federal regulations mandate the conduct of a clinical research trial, human research participant protection, and the informed consent process. IMPLICATIONS FOR NURSING PRACTICE The oncology nurse supports the autonomy and safe conduct of the human research participant during a clinical research trial and provides education and support through the informed consent process. OBJECTIVES To describe the evolution and structure of the National Cancer Institute clinical trials programs, their notable accomplishments, nurses' roles in these accomplishments, and the essential role of nursing today and in the future. DATA SOURCES Manuscripts, government publications, websites, and professional communications. CONCLUSION Change is inevitable and a constant factor in the world of advancing science and clinical research. Nurses' contribution to research and evidence-based practice will continue to grow and is vital as the scientific landscape evolves. IMPLICATIONS FOR NURSING PRACTICE As the understanding of cancer biology increases and clinical trials evolve, nurses will need to remain key team members and leaders in National Cancer Institute Community Oncology Research Program and National Cancer Trials Network trials and their associated infrastructure.

Yet, emerging Nipah, Ebola and Zika viral diseases outbreaks have been indirectly linked to substantially globalization of trade and travel, climate change and intense urbanization impact, healthcare and socioeconomic inequities as well in affected community settings. Although no case has been documented in Saudi Arabia, there is a great risk of sudden emergence of any of these viruses and others via introducing among pilgrims coming from endemic regions during ritual ceremonies of mass gatherings. Consequently, promoting and investing on new and sensitive proven effective and innovative surveillance and monitoring approaches, including enhanced risk communication, improved integrated vectors surveillance in addition to improved sustainable highly pathogens surveillance control programs to human motility and environmental sanitation strategies all represent 'Oneffectiveness is needed through One Health approach integration in attaining pilgrims and local population health safety and security, in advancing Saudi sustainable health development goals. BACKGROUND The usefulness of laboratory tests in the decision-making process with regard to early identification of dengue virus infection has not been widely reported, particularly the aspartate aminotransferase (AST)/platelet count ratio index during a patient's days of illness. The aim of this study was to examine the pattern of the ratio index over the course of illness and identify whether it is a marker of dengue virus infection in dengue patients, as well as to assess the role of other laboratory tests. METHODS A chart review of 205 dengue patients was analyzed using available records of 845 laboratory results within different time intervals or exam dates during the course of illness. We used repeated measures mixed binary logistic regression analyses to model the dengue virus infection, defined as giving at least one positive antibody test (yes/no). RESULTS The high risk of dengue virus infection in dengue patients was found in the male gender (adjusted OR=4.316, 95% CI 1.285-14.498, P=0.018), in patients with a high AST/platelet count ratio index (adjusted OR=1.438, 95% CI 1.057-1.957, P=0.021), in patients with a low MCV level (adjusted OR=0.815, 95% CI 0.679-0.978, P=0.028), and in patients with a low ALT level (adjusted OR=0.996, 95% CI 0.993-0.999, P=0.010). CONCLUSION Laboratory markers, in particular the AST/platelet count ratio index, can be useful for clinicians to strengthen the decision-making process in primary care settings. Furthermore, our model revealed that low MCV and low ALT are predictors of the dengue virus infection, while being a male increases the risk of dengue virus infection. More studies are needed to evaluate the impact of the AST/platelet count ratio index on the severity of dengue fever infection during the onset of symptoms and course of treatment. https://www.selleckchem.com/products/mitapivat.html Stress can induce reproductive deficits by activating the HPA and causing oxidative stress. Some studies have indicated that the neurologic diseases or disorders induced by stress could be relieved by probiotics. Whether chronic unpredictable stress (CUS)-induced reproductive deficits could be prevented by probiotics is unclear. The present experiment was designed to evaluate the effects of L. rhamnosus Gorbach-Goldin (LGG) on CUS-induced reproductive deficits. Kunming mice were divided into control, stress, and LGG groups randomly. The mice in stress and LGG groups were exposed to CUS for 40days, in the meantime, the mice in LGG group were orally administered with LGG suspension at a dose of 0.3 mL/mouse (1×1010 cells/mL), and the mice in control and stress groups were orally administered with volume-equivalent sterile saline once a day. The results showed that the CUS-induced the sperm deficits including the count, motility, morphology, ultrastructure, DNA integrity, and chromatin condensation were protected by oral administration of LGG. In addition, the change of testosterone level induced by CUS was prevented by up-regulating the expressions of StAR and P450scc in the testes. Moreover, LGG could increase the activities of catalase, glutathione peroxidase, and superoxide dismutase significantly, and decrease the levels of oxidative products malondialdehyde and protein carbonyls significantly, as well as the levels of cyclooxygenase 2, interleukin (IL)-1β, IL-6, and tumor necrosis factor-α, to block the CUS-induced inflammatory response and the oxidative stress. The results indicated that the CUS-induced male reproductive deficits could be prevented by oral administration of LGG. V.PURPOSE Radiomics are a set of methods used to leverage medical imaging and extract quantitative features that can characterize a patient's phenotype. All modalities can be used with several different software packages. Specific informatics methods can then be used to create meaningful predictive models. In this review, we will explain the major steps of a radiomics analysis pipeline and then present the studies published in the context of radiation therapy. METHODS A literature review was performed on Medline using the search engine PubMed. The search strategy included the search terms "radiotherapy", "radiation oncology" and "radiomics". The search was conducted in July 2019 and reference lists of selected articles were hand searched for relevance to this review. RESULTS A typical radiomics workflow always includes five steps imaging and segmenting, data curation and preparation, feature extraction, exploration and selection and finally modeling. In radiation oncology, radiomics studies have been published to explore different clinical outcome in lung (n=5), head and neck (n=5), esophageal (n=3), rectal (n=3), pancreatic (n=2) cancer and brain metastases (n=2). The quality of these retrospective studies is heterogeneous and their results have not been translated to the clinic. CONCLUSION Radiomics has a great potential to predict clinical outcome and better personalize treatment. But the field is still young and constantly evolving. Improvement in bias reduction techniques and multicenter studies will hopefully allow more robust and generalizable models. INTRODUCTION It is common practice to prescribe prophylactic antiepileptic drugs (AED) to high-grade glioma (HGG) patients without a history of seizures, yet with limited evidence supporting its use. Ideally, the effectiveness of prophylactic anticonvulsants must outweigh the occurrence of adverse effects and interactions related to AED. The authors conducted a systematic review and metanalysis of longitudinal studies regarding the effectiveness of prophylactic AED in seizure-naïve HGG patients. MATERIALS AND METHODS PubMed/MEDLINE, Cochrane Central Register of Controlled trials, Embase and clinicaltrials.gov databases were systematically searched. Of the initial 1773 studies identified, 15 were finally selected for data extraction and analysis. Heterogeneity among studies, pooled hazard ratios, publication bias and sensitivity analyses were performed separately for a 15-study group (HGG patients within larger series of brain tumors) and a 6-study group (exclusively HGG patients). RESULTS AED prophylaxis did not significantly reduce the incidence of postoperative seizures compared with controls, both in the 15-study group (Mantel-Haenszel random-effects pooled OR 1.
