The population-level burden of HPV-positive OPSCC is currently unidentified and may have important implications to cancer prevention, potentially through HPV vaccination. Therefore, combined molecular epidemiologic methods that use both sensitive and specific laboratory assays with cancer surveillance methods to investigate the changes in the population-level epidemiology of OPSCC in the United States are caused by HPV infection to estimate the historical, current, and future population-level burden of HPV-positive OPSCCs.
HPV阳性OPSCC的人群水平负担目前尚未确定,可能对通过HPV疫苗预防癌症具有重要意义。因此,结合分子流行病学方法,使用敏感和特异性实验室检测与癌症监测方法来调查HPV感染引起的美国OPSCC人群水平流行病学的变化,以估计HPV阳性OPSCC的历史、当前和未来人群水平负担。

Background: The Corona Virus Disease 2019 (COVID-19) caused by the novel Coronavirus strain Severe Acute Respiratory Syndrome-Corona Virus 2 (SARS-CoV-2) is currently a pandemic. On January 30, 2020, the World Health Organization declared that the COVID-19 outbreak is a public health emergency of international concern. The lockdown across the countries has resulted in a postponement of routine immunization programs following the recommendations of maintaining a physical distance. Delay of routine pediatric vaccinations, even for a short duration will result in an increased likelihood of vaccine-preventable. The primary objective of this research is to assess the impact of the COVID-19 pandemic on the routine childhood vaccination coverage rate in the eastern region of Saudi Arabia. Methods: A cross-sectional study through an online questionnaire. The targeted population was both male and female adults who have children at the age of vaccinations who are residents of the eastern region of Saudi Arabia during the period between July 2020 and September 2020. Results: 494 respondents participated in this study. 378 of them have children. 76.5% of them have Children had vaccination schedule during COVID-19 pandemic. 66.9 vaccinated their children. 33.1% of parents their children did not receive vaccines during COVID-19. 82.8% of parents think vaccines should be given at its time even during the COVID pandemic. Conclusion: One out of every three children has missed their routine vaccinations during the COVID-19. The pool of unimmunized children is expanding during the lockdown, making them susceptible to vaccine-preventable diseases. Most of the parent knows the importance of routine pediatric vaccinations.
背景:由新型冠状病毒株-严重急性呼吸综合征-冠状病毒2 (SARS-CoV-2)引起的2019冠状病毒病(COVID-19)目前处于大流行状态。2020年1月30日,世界卫生组织宣布新冠肺炎疫情为国际关注的突发公共卫生事件。根据保持身体距离的建议,各国的封锁导致常规免疫计划推迟。延迟常规儿科疫苗接种,即使是短时间,也会导致疫苗可预防的可能性增加。本研究的主要目的是评估2019冠状病毒病大流行对沙特阿拉伯东部地区常规儿童疫苗接种覆盖率的影响。方法:通过在线问卷进行横断面研究。目标人群是2020年7月至2020年9月期间居住在沙特阿拉伯东部地区的男性和女性成年人,他们的孩子在接种疫苗的年龄。结果:494名受访者参与了本研究。其中378人有孩子。76.5%的儿童在新冠肺炎大流行期间接种了疫苗。66.9人给孩子接种疫苗。在COVID-19期间,33.1%的家长其子女未接种疫苗。82.8%的家长认为即使在COVID大流行期间也应该接种疫苗。结论:在2019冠状病毒病期间,每三个儿童中就有一个错过了常规疫苗接种。在封锁期间,未接种疫苗的儿童人数正在扩大,使他们容易感染疫苗可预防的疾病。大多数家长都知道儿童常规接种疫苗的重要性。

Viruses have evolved by surviving in hosts over millions of years. The human immune system has also co-evolved to counter the escape mechanisms of viruses. Each virus has a unique and specific mechanism of causing disease. SARS-COV2 has emerged as a newly mutated virus that has resulted in a world-wide pandemic. Understanding immunobiology of viruses provides information on developing diagnostics, therapeutics, and vaccines. We have reviewed and summarized the pathogenesis of four viruses that have emerged as causative agents for endemics in the past decade. Dengue, Chikungunya, Nipah and Zika viruses i) are transmitted by different intermediate animal hosts, ii) infect cells through different receptors, iii) induce a diverse range of symptoms, iv) which are treated with specific and symptomatic therapies, and v) various proteins expressed by the viruses used as antigens for diagnosis and development of vaccines. The nature of the immune response to these viruses involves innate, cell mediated and humoral immunity, and several proteins of these viruses have been implicated in protective versus pathogenic responses. We have summarized and provided recent references for the current understanding of SARS-COV2 virus and immunological immune responses, and listed similarities and difference in characteristics to these four viruses. This systematic analysis of these viruses will enable the understanding the requirements and anticipate challenges in development of novel diagnostics, therapies, and vaccines for COVID-19 pandemic.
病毒通过在宿主体内存活数百万年而进化。人类免疫系统也共同进化以对抗病毒的逃逸机制。每种病毒都有其独特的致病机制。SARS-COV2是一种新变异的病毒,已导致全球大流行。了解病毒的免疫生物学为开发诊断、治疗和疫苗提供了信息。我们回顾和总结了四种病毒的发病机制,这些病毒在过去十年中已经成为地方性传染病的病原体。登革热病毒、基孔肯雅病毒、尼帕病毒和寨卡病毒1)由不同的中间动物宿主传播,2)通过不同的受体感染细胞,3)诱发各种各样的症状,4)用特异性和对症疗法治疗,以及5)由病毒表达的各种蛋白质,用作诊断和开发疫苗的抗原。对这些病毒的免疫反应的性质包括先天免疫、细胞介导免疫和体液免疫,这些病毒的几种蛋白质与保护性和致病性反应有关。我们对目前对SARS-COV2病毒和免疫应答的认识进行了总结,并提供了近期的参考,列出了与这四种病毒特征的异同。对这些病毒的系统分析将有助于了解针对COVID-19大流行的新型诊断、治疗和疫苗开发的要求并预测挑战。

Evaluation of Diversity Levels of the Integrase Gene Sequences Coming from HIV-1 Virus, Supporting the Lack of Target Specificity of Ivermectin vs. the Integrase-Importin Complex in SARS-COV-2 Infection 来自HIV-1病毒整合酶基因序列多样性水平的评估,支持伊维菌素与整合酶输入复合物在SARS-COV-2感染中缺乏目标特异性

Therapies with new drugs have been appearing in tests worldwide as potential inhibitors of sars-cov-2 virus replication. Recently, one of these drugs, Ivermectin, was reported as an inhibitor of the nuclear import of HIV-1 proteins in vitro, soon becoming the target of an international prospecting work (not yet published), with patients tested for COVID-19. However, understanding the evolutionary aspects of the biological components involved in the complex drug-nuclear import helps in understanding how these relationships exist in the deactivation of viral infections. Thus, 153 sequences of the HIV-1 integrase gene were analyzed for their genetic structure and molecular diversity and the presence of two distinct groups for the Gene and not only one was detected as well as different degrees of structuring for each of these groups. These results support the interpretation of the lack of conservation of the HIV-1 gene and that the number of existing polymorphisms, only for this structure of the complex, implies the non-efficiency of a drug at population levels. Thus, the molecular diversity found in HIV-1 can be extrapolated to other viruses, such as Including, SARS-CoV-2 and the functionality of the drug, interacting with the integrase-importin complex, can be further decreased.
在世界各地的测试中,新药物疗法作为潜在的sars-cov-2病毒复制抑制剂已经出现。最近,其中一种药物伊维菌素被报道为体外HIV-1蛋白核输入抑制剂,很快成为一项国际勘探工作的目标(尚未发表),并对患者进行了COVID-19检测。然而,了解复杂药物核输入中涉及的生物成分的进化方面有助于理解这些关系如何存在于病毒感染的失活中。因此,我们分析了HIV-1整合酶基因的153个序列,分析了它们的遗传结构和分子多样性,发现该基因存在两个不同的群体,而且不仅检测到一个群体,而且每个群体的结构程度不同。这些结果支持了HIV-1基因缺乏保守性的解释,以及现有多态性的数量,仅针对这种复合物的结构,意味着药物在群体水平上无效。因此,在HIV-1中发现的分子多样性可以推断到其他病毒,如包括SARS-CoV-2,并且药物与整合酶输入蛋白复合物相互作用的功能可以进一步降低。

The importance of global group B streptococcal (GBS) colonization during pregnancy is briefly reviewed in this short article. About 20% all pregnant women worldwide are colonized with this organism necessitating the use of intrapartum antibiotic prophylaxis (IAP) in order to prevent neonatal GBS disease. In some geographic regions rates of colonization are as high as 35%. Such a high rate of IAP is shown to be concerning because of childhood adverse effects. We briefly summarize 5 main childhood adverse outcomes from IAP which include antibiotic resistance, the development of various atopic diseases, dysbyosis, obesity, and impaired immune function. Finally, the article clearly lists 4 reasons why a GBS vaccine is specifically urgently needed in order to curb the often unnecessary if not dangerous use of IAP to prevent against the onset of neonatal GBS disease. It is hoped that such a vaccine could reduce the rate of IAP from a high of 40% to a low of 10%.
全球B族链球菌(GBS)定植在怀孕期间的重要性简要回顾在这篇简短的文章。全世界约有20%的孕妇定植有这种微生物,需要使用产时抗生素预防(IAP)来预防新生儿GBS疾病。在一些地理区域,殖民化率高达35%。如此高的IAP率令人担忧,因为它会对儿童产生不良影响。我们简要总结了IAP的5个主要儿童不良后果,包括抗生素耐药性、各种特应性疾病的发展、营养不良、肥胖和免疫功能受损。最后,文章明确列出了4个原因,说明为什么迫切需要一种GBS疫苗,以遏制IAP的使用,这种使用往往是不必要的,如果不是危险的,以预防新生儿GBS疾病的发生。希望这种疫苗可以将IAP的比率从40%的高位降低到10%的低位。

Crohn's disease may be a sort of inflammatory bowel disease (IBD). It causes inflammation of your alimentary canal, which may cause abdominal pain, severe diarrhoea, fatigue, weight loss and malnutrition. Inflammation caused by regional enteritis can involve different areas of the alimentary canal in several people. A chronic inflammatory bowel disease that affects the liner of the alimentary canal. Crohn's disease can sometimes cause lifethreatening complications. Crohn's disease can cause abdominal pain, diarrhoea, weight loss, anaemia and fatigue. Some people could also be symptom-free most of their lives, while others can have severe chronic symptoms that never get away. Crohn's disease can't be cured. Medications like steroids and immunosuppressant’s are wont to slow the progression of disease. If these aren't effective, a patient may require surgery. Additionally, patients with regional enteritis may have to receive regular screening for colorectal cancer thanks to increased risk.
克罗恩病可能是一种炎症性肠病(IBD)。它会引起消化道炎症,从而引起腹痛、严重腹泻、疲劳、体重减轻和营养不良。局部肠炎引起的炎症可累及几个人消化道的不同部位。肠病一种影响消化道内壁的慢性炎症性肠病克罗恩病有时会导致危及生命的并发症。克罗恩病可引起腹痛、腹泻、体重减轻、贫血和疲劳。有些人可能一生中大部分时间都没有症状,而另一些人可能有严重的慢性症状,永远不会消失。克罗恩病无法治愈。类固醇和免疫抑制剂等药物通常会减缓疾病的进展。如果这些都不起作用,病人可能需要手术。此外,由于风险增加,患有区域性肠炎的患者可能必须定期接受结直肠癌筛查。

Vaccine is an organic solution which provides immunity against certain infectious diseases. It consists of a biological agent to simulate a disease causing microorganism and a weaker form of microbes, toxins or its surface proteins. These agents recognize any foreign particle entering into the body and indicate it as a threat in order to destroy it. Vaccine improves the active immunity against harmful agents. Vaccines also provide antibodies already released in another host. The administration includes parenteral administration, oral and sometimes nasal form. Vaccine research is made possible with the help of biotechnology department. Due to the innovative studies regarding vaccines, vaccine development has been made possible for many infectious and dreadful diseases. The development of vaccine takes several steps.
疫苗是一种有机溶液,可以提供对某些传染病的免疫力。它由模拟致病微生物的生物制剂和较弱形式的微生物、毒素或其表面蛋白质组成。这些药物能识别任何进入体内的外来粒子并将其视为威胁,从而消灭它。疫苗提高了对有害物质的主动免疫力。疫苗还提供已经在另一个宿主体内释放的抗体。给药方式包括肠外给药、口服和有时鼻腔给药。在生物技术部门的帮助下,疫苗研究成为可能。由于疫苗方面的创新研究,使得许多传染病和可怕疾病的疫苗开发成为可能。疫苗的研制需要几个步骤。

The Burden of Disease from Congenital Rubella Syndrome in Lesotho 莱索托先天性风疹综合征的疾病负担
Pub Date : 2020-01-01 DOI: 10.35248/2157-7560.20.11.415
Thabelo Makhupane, A. B. Nwako
Background: Congenital rubella syndrome (CRS) causes severe birth defects and is preventable. In line with the global vision for measles and rubella elimination, Lesotho introduced the measles-rubella (MR) vaccine into the routine immunization schedule in February 2017. The aim of the study was to show the burden of CRS in Lesotho before the introduction of the rubella vaccine. Methods: This was a cross-sectional descriptive study. Data was extracted from several sources at Queen Mamohato Memorial Hospital including inpatient, outpatient, electronic and laboratory records as well as expert interviews. Files of infants less than 12 months with CRS during the period January 2012 to December 2016 were selected. Results: There were five laboratory and 4 clinically confirmed CRS cases. One case also had Cytomegalovirus (CMV) co-infection. Mohales’ Hoek district had the highest number of cases (33.3%). Six of the districts had at least one case of CRS within the study period. There were no cases in 4 districts. Most (56%) of the CRS cases were reported in 2015. We were unable to determine the incidence of CRS in Lesotho in this study. Conclusion: The detection of 9 CRS cases in Lesotho over the period under review is of high public health importance.There is an immunity gap among mothers of child bearing age which shows an opportunity for future immunization. Prospective CRS case-based surveillance would be useful in determining accurate estimates of the burden of CRS and the impact of the introduction of rubella-containing vaccine into the routine immunization schedule.
背景:先天性风疹综合征(CRS)导致严重的出生缺陷,是可以预防的。根据消除麻疹和风疹的全球愿景,莱索托于2017年2月将麻疹-风疹(MR)疫苗纳入常规免疫计划。这项研究的目的是显示在引入风疹疫苗之前莱索托CRS的负担。方法:采用横断面描述性研究。数据摘自Mamohato皇后纪念医院的几个来源,包括住院、门诊、电子和实验室记录以及专家访谈。选取2012年1月至2016年12月期间12个月以下CRS患儿档案。结果:实验室确诊CRS 5例,临床确诊CRS 4例。1例合并巨细胞病毒(CMV)感染。Mohales的Hoek区病例数最多(33.3%)。其中6个地区在研究期间至少有1例CRS病例。4个区无病例。大多数CRS病例(56%)报告于2015年。在本研究中,我们无法确定莱索托CRS的发病率。结论:在本报告所述期间,莱索托共发现9例CRS病例,对公共卫生具有重要意义。育龄母亲之间存在免疫力差距,这表明今后有机会进行免疫接种。基于病例的CRS前瞻性监测将有助于确定准确估计CRS负担和将含风疹疫苗引入常规免疫计划的影响。

The crisis of the Covid-19 that we are currently experiencing has been a huge turning point in the life of many of us, but will certainly bring a radical turn in our lives. In broad sense; dimensions of health/disease can be described as; biological, socioeconomic, environmental, cultural, political. While majority of the above dimensions are being studied around the world, some of the less mentioned determinants are; Planets and disease (Astrology), role of Integrative Medicine that mainly focuses on behavior modification and prevention of diseases, role of Alkaline diet to boost immune system, role of life style modification viz; Physical fitness, importance of Sleep, Positive Mind as a major part of spiritual awakening. The current article through light on some of these less talked dimensions. It shall need an integration of various approaches; pharmacological and non- pharmacological and a lot of community participation (more of a community level fight) at community level mostly related to health promotion and specific protection (life style modification and adaptation) so that patients coming to the hospital are reduced so that hospitals are not strained.
我们目前正在经历的Covid-19危机是我们许多人生活中的一个巨大转折点,但肯定会给我们的生活带来根本性的转变。广义上的;健康/疾病的层面可以描述为:生物的,社会经济的,环境的,文化的,政治的。虽然世界各地正在研究上述大多数方面,但一些较少提及的决定因素是;行星与疾病(占星术),主要关注行为改变和疾病预防的中西医结合的作用,碱性饮食增强免疫系统的作用,改变生活方式的作用;身体健康,睡眠的重要性,积极的心态是精神觉醒的主要部分。本文将从这些较少讨论的方面入手。它需要综合各种办法;药理学和非药理学有很多的社区参与(更多的是社区层面的斗争),在社区层面主要涉及到健康的促进和具体的保护(生活方式的改变和适应),使来医院的病人减少,使医院不紧张。

Vaccine hesitancy is defined as the reluctance or refusal to vaccinate despite the availability of vaccines. The World Health Organization identified Vaccine hesitancy as one of the ‘Ten threats to global health in 2019. Vaccine hesitancy affects not only the individuals but also the society by attributing to a decline in 'Herd Immunity'- a concept central to the success of vaccination campaigns. Despite being refuted by more credible sources, misinformation about vaccines continue to pave way for mistrust upon vaccines, even in economically weaker countries where vaccine coverage is inadequate. Religious beliefs and previous experiences with vaccination influence vaccine seeking behavior. Adverse Events following immunization (AEFI) may be an important factor with respect to newly launched vaccine programs. Numerous strategies have been employed including but not limited to educating target population, employing reminder and follow-up, engaging religious or other influential leaders to promote vaccination, and making vaccination mandatory. While the success of each of these strategies varies from place to place, mandating vaccination has faced some vocal opposition in the past. Vaccine hesitancy is not likely to be noticed by the common healthcare provider unless another disease outbreak attributable to it is noticed. Hence, it is imperative for the medical community to look into this matter with utmost seriousness and identify and devise strategies that cull this dilemma with an approach to understand the lacunae in knowledge or attitude of the recipients.
疫苗犹豫被定义为尽管有疫苗,但不愿意或拒绝接种疫苗。世界卫生组织将疫苗犹豫确定为2019年全球健康的十大威胁之一。疫苗犹豫不仅影响个人,也影响社会,原因是“群体免疫力”的下降——这是疫苗接种运动成功的核心概念。尽管有更可靠的来源予以驳斥,但关于疫苗的错误信息继续为不信任疫苗铺平道路,即使在疫苗覆盖率不足的经济较弱的国家也是如此。宗教信仰和以前接种疫苗的经历会影响寻求疫苗的行为。免疫不良事件(AEFI)可能是新推出疫苗计划的一个重要因素。采用了许多策略,包括但不限于教育目标人群、采用提醒和后续措施、聘请宗教或其他有影响力的领导人促进疫苗接种,以及强制接种疫苗。虽然每种策略的成功程度因地而异,但强制接种疫苗在过去曾面临一些强烈反对。疫苗犹豫不太可能被普通医疗保健提供者注意到,除非注意到另一种可归因于此的疾病爆发。因此,医学界必须极其认真地研究这一问题,并确定和制定策略,以了解接受者在知识或态度上的空白来消除这种困境。
