Since the emergence of COVID 19 virus, scientists all over the world are working at breakneck speed to develop a vaccine. Development of a vaccine is not a competitive race to the finish as it must pass through a stringent process of evaluation. The process includes vaccines’ immunogenicity, duration of immunity, efficacy of protection, interaction with other antigens, dosage, route of administration, packaging, and thermostability and expected adverse events and safety. Efficacy of a new vaccine is measured in clinical trials under ideal conditions, whereas its effectiveness is measured in the field under actual program conditions. (1) In normal circumstances, vaccine development is a prolonged process, averaging over 10 years from start to finish (2). To meet the urgent, need a COVID 19 vaccine may be available in a much shorter-term frame, at the earliest in 18 months.

Background:Hypertension occurred in 30-80% of TAK patients around the world. The occurrence of hypertension might severely worsen TAK prognosis. Nevertheless, data describing the specific imaging features in hypertensive TAK patients and the associations between hypertensive severity, blood pressure control status and long-term outcome were still lacking.Objectives:To investigate the characteristics and associations of hypertensive characteristics with adverse events-free survival in Takayasu arteritis (TAK) patients with hypertension.Methods:This research was based on a prospectively on-going observational cohort-East China Takayasu Arteritis (ECTA) cohort. In all, 618 TAK patients, who registered in the ECTA cohort up to December 2019, were enrolled. The main outcome was the adverse-events-free survival among hypertensive TAK patients during the follow-up ended on August 2020.Results:Totally, 204 (33.0%) patients suffered from hypertension, with 48 (23.5%), 62 (30.4%), and 94 (46.1%) mild, moderate, and severe hypertension, respectively. Cluster analysis indicated three imaging phenotypes for hypertensive TAK patients: Cluster 1: involvement of the abdominal aorta and/or renal artery (n=56, 27.5%); Cluster 2: involvement of the ascending aorta, thoracic aorta, and the aortic arch and its branches (n=38, 18.6%); Cluster 3: combined involvement of Cluster 1 and Cluster 2 (n=111, 54.4%). By the end of the follow-up, the blood pressure control rate was 50.8%, while the adverse-events-free survival was 67.9% in the entire hypertensive population. Multivariate Cox regression analysis indicated that well-controlled blood pressure (HR=2.13, 95%CI 1.32–3.78, p=0.047), co-existence of severe aortic valve regurgitation (HR=0.87, 95%CI 0.64–0.95, p=0.043), Cluster 1 (HR=0.69, 95%CI 0.48–0.92, p=0.017) and Cluster 3 (HR=0.72, 95%CI 0.43–0.94, p=0.048) imaging phenotype was associated with the adverse-events-free survival.Conclusion:Patients with controlled hypertension showed better adverse-events-free survival, while those with the Cluster 1 imaging phenotype were more likely to suffer from worse adverse-events-free survival. Hypertension occurred in 30-80% of TAK patients around the world. The occurrence of hypertension might severely worsen TAK prognosis.References:[1]Johnston SL, Lock RJ, Gompels MM.

Background and Objectives: Oral cancer is the 6th most common cancer in the world and oral leukoplakia is an oral potentially malignant disorder that could develop into oral cancer. This systematic review focusses on randomized clinical trials for recombinant adenovirus p-53 (rAD-p53) therapy for the treatment of oral leukoplakia and cancer. Materials and Methods: We searched for research articles on various databases such as Pubmed/Medline, Embase, CNKI (China National Knowledge Infra-structure), Springerlink, cochrane and Web of sciences from 2003 to 2020. MeSH (Medical Subject Headings) terms were used for the search. Inclusion criteria included original research, randomized clinical trials and articles only in English language. Exclusion criteria were any articles that were not research articles, not randomized trials, non-human studies, etc. The articles were further graded on the Jadad scale. Results: 578 articles were assessed from various databases; only 3 articles were found to be appropriate for this review. Thus, meta-analysis was not performed because of heterogeneity and lack of data. In the three studies, whether rAD-p53 was used as a standalone therapy or with other therapies, there was a beneficial effect of the therapy. Furthermore, there were no serious adverse events and the only adverse events reported were fever, pain at the local injection site, flu-like symptoms and lowered WBC count. Conclusions: Thus, we can conclude that this therapy has a potential for beneficial therapeutic effects and further clinical trials with more patients need to be performed to get better understanding of the effect of rAD-p53 therapy, which probably will pave the way to its approval in other parts of the world.

Coronavirus disease-2019 (COVID-19) has affected countries around the world. The introduction of COVID-19 vaccines has proved the most effective arsenal in the fight against the disease. However, with the vaccination of billions of people, data on vaccine-induced adverse reactions are also emerging. We report a 32-year-old woman who manifested papulopustular rash 7 days after receiving Moderna COVID-19 (mRNA-1273) vaccine. The patient responded to a short course of systemic steroids and antihistamines. Awareness regarding the possible adverse events that can be anticipated after the COVID-19 vaccination may help the healthcare professionals to offer prompt and effective care to the affected.

7013 Background: Hairy cell leukemia (HCL) is rare B-cell lymphoproliferative disorder. Its treatment has evolved from splenectomy with time to failure (TTF) of 19 months to Cladribine that increased complete remission (CR) rate to 90%, with only small percentage of patients relapsing at 30 months. Cladribine (CDA) is originally administered intravenously as continuous infusion for 7 days; Subsequently, it was administered subcutaneously. This study aims at comparing efficacy and toxicity of Subcutaneous (SC) versus Intravenous (IV) administration of CDA in treatment of HCL. Methods: This retrospective study included HCL patients presented to National Cancer Institute and Nasser Institute, Cairo, Egypt, during period 2004-2010. Included patients received CDA as 1st or 2nd line with minimum follow up of 12 months. All files were reviewed for baseline clinical & laboratory parameters, route of administration, response, adverse events and survival. Results: This study included 49 eligible patients, 41 patients received CDA as 1st line treatment, while 8 patients as 2nd line. Eighteen patients were treated by continuous IV infusion whereas 31 patients by SC injections. Both groups were comparable regarding baseline clinical and laboratory parameters with no statistically significant difference. At median follow up period of 33.5 months, complete remission rate was 94% in IV group versus 97% in SC group (p=0.691); median TTF for IV group was 52.9 months while that for SC group was not reached (p=0.035). The median time to achieve CR in both arms was similar. By analyzing different factors affecting TTF using multivariate analysis, route of administration proved to be the only statistically significant factor (P=0.006). Regarding adverse events, there was no difference between both groups in hematological toxicities. IV route was associated with a significant higher incidence of mucositis (p=0.02) and viral infections (p=0.01). Hepatotoxicity and neurotoxicity were higher in SC group but difference was not statistically significant. Conclusions: SC administration of cladribine is an alternative route to IV in treatment of HCL with similar response rate, longer time to treatment failure and better tolerability.

Purpose The purpose of this paper is to highlight that the lack of a specific right to a medical translator under International Law can be considered an outlier when viewed within the context of the copious legislation regarding translation in general. Given the lack of specific legislation guaranteeing the right to a medical translator under International Law, the paper further aims to highlight the resulting effects on medical providers and patients. Design/methodology/approach The paper opted for a detailed historical legal analysis regarding the history of translation under International Law in general, as well as specific international, intranational, and regional legislation regarding the right to a translator in medical settings. The data were complemented by a thorough review of documentary analysis of existing scholarship, detailing the experiences of medical providers and patients. Findings The paper provides insights as to how international legislators have traditionally viewed medical translation: whether as a matter of international relations, access to care, discrimination, or as a fundamental part of the Right to Health. The paper finds that differing views on the subject have result in nations, regions, and medical providers having great discretion in deciding which patients are provided with a translator. The paper finds that such decisions are often made on a basis other than that of patient health. Research limitations/implications Because the provisioning of translators in medical settings currently inevitably falls to a nation or single institution, research into which patients receive a translator and why lacks generalizability (because empirical data are not available for every region of the world). Researchers in future are encouraged to further develop the empirical evidence found in their regions with a more quantitative approach, documenting the non-provisioning of translators in their areas and categorizing the motives behind the decisions of medical providers in a given area. Practical implications The paper includes implications for patients who have suffered adverse events after miscommunication (or lack of communication) with their medical providers. The paper aims to investigate in what venue may they seek legal remedy, and on what grounds. The paper also has implications for national and regional governments. Given the lack of binding International Law regarding medical translation, national and regional governments attempt to guarantee the provisioning of translators to some patients and not others. Such decisions may become political and have unintended consequences for medical providers and patients alike. Social implications The paper includes implications for international legislators and national legislators. The paper also includes implications for medical providers and patients, as language barriers are becoming a more common feature in medical facilities around the world due to globalization and migration. The rate of patients suffering adverse events after not being provided with a competent medical interpreter is bound to rise. Originality/value This paper fulfills a need to examine medical translation in the context of other types of translation under International Law. This paper fulfills a need to study how the lack of specific International Legislation guaranteeing the right to medical translation has implications for national/regional legislators, medical providers, and patients alike. This paper fulfills a need to discuss the legal remedies available to patients who have suffered adverse medical events after not being able to communicate with their medical provider.

Moxibustion is a traditional medical treatment originating in China. It involves using the heat of burning moxa to stimulate acupoints. It is considered safe and effective and is widely used throughout the world. The increasing use of moxibustion has drawn attention to the procedure’s adverse events (AEs). This review covers a total of 64 cases of AEs associated with moxibustion in 24 articles, reported in six countries. Some evidence of the risks of moxibustion has been found in these cases. AEs include allergies, burns, infection, coughing, nausea, vomiting, fetal distress, premature birth, basal cell carcinoma (BCC), ectropion, hyperpigmentation, and even death. The position, duration, distance between moxa and skin, proficiency of the practitioners, conditions of the patients, presence of smoke, and even the environment of treatment can affect the safety of moxibustion. Improving practitioner skill and regulating operations may reduce the incidence of adverse reactions and improve the security of moxibustion.
