AbstractAt the end of 2019, a new coronavirus infection occurred in the People’s Republic of China with an epicentre in the city of Wuhan. On February 11th, 2020, the World Health Organization assigned the official name of the infection caused by the new coronavirus – COVID-19. COVID-19 has affected people from all over the world given that the infection was noted in 200 countries resulting in annunciation of the pandemic situation. Human corona viruses cause mild to moderate respiratory infections. At the end of 2002, a new coronavirus appeared (SARS-CoV), the causal agent of atypical pneumonia, which caused acute respiratory distress syndrome (ARDS). The initial stage of COVID-19 infection is the penetration of SARS-CoV-2 into target cells that have angiotensin converting enzyme type II receptors. The virus enters the body through the respiratory tract and interacts primarily with toll-like receptors (TLRs). The events in SARS-Cov-2 induced infection follow the next scenario: epithelial cells via TLRs recognize and identify SARS-Cov-2, and after that the information is transmitted to the transcriptional NF-κB, which causes expression of the corresponding genes. Activated in this way, the epithelial cells begin to synthesize various biologically active molecules. The results obtained on preclinical material indicate that ROS generation increases and the antioxidant protection decreases, which plays a major role in the pathogenesis of SARS-CoV, as well as in the progression and severity of this respiratory disease.

The World Health Organization (WHO) has recognized obesity as one of the top ten threats to human health. It is estimated that the number of obese and overweight people worldwide exceeds the number of those who are undernourished. Obesity is not only a state of abnormally increased adipose tissue in the body, but also of increased release of biologically active adipokines. Adipokines released into the circulating blood, due to their specific receptors on the surface of target cells, act as classic hormones affecting the metabolism of tissues and organs. What is more, adipokines and cytokines may decrease the insulin sensitivity of tissues and induce inflammation and development of chronic complications. Certainly, it can be stated that in an era of a global obesity pandemic, adipokines may gain more and more importance as regards their use in the diagnostic evaluation and treatment of diseases. An extensive search for materials on the role of white, brown and perivascular fatty tissue and obesity-related metabolic and chronic complications was conducted online using PubMed, the Cochrane database and Embase.

One of the global, vital problems of humanity is iodine deficiency. According to the World Health Organization (WHO), more than 2 billion people live in conditions of iodine deficiency. people: among them, 740 million have endemic goiter, 43 million have mental retardation, more than 6 million. they suffer from cretinism (an extreme degree of mental retardation). Currently, iodine deficiency diseases are the most common non-infectious diseases in the world. What about mammalian animals? In animals, iodine performs the same functions as in humans. Animals, especially agricultural animals, are just as sensitive to iodine deficiency as humans. With a lack of iodine in the body of animals, the biosynthesis of thyroid hormones is disrupted, which leads to a decrease in the intensity of redox processes, as a result of which all types of metabolism are disrupted:-protein, fat, carbohydrate, macro – and microelement, energy. In this regard, the failure of the thyroid gland is accompanied by the development of severe pathobiochemical processes, which, in the end, leads to the clinical manifestation of pathophysiological conditions. Taking into account the fact that in conditions of constant iodine deficiency it is very problematic to ensure the health of productive animals, the issues of prevention of iodine deficiency conditions are economically significant for industrial animal husbandry. It is no accident that in countries experiencing natural iodine deficiency, state programs have been developed that provide for the use of iodine-containing additives in the diets of productive animals. Despite the fact that the simplest and most affordable method of eliminating iodine deficiency in humans and animals is the inclusion of iodized salt in the diet, however, this method can not be used for veterinary purposes. First of all, the feed method of using biologically active additives eliminates the possibility of dosed therapeutic or preventive treatment. On the pages of this article, we draw attention to the emerging prospects for the use of a new iodine-metabolic composition in non-infectious and infectious pathology, based on an iodine polymer complex known in pharmacology as iodinol and succinic acid.

Coronavirus disease 2019 (COVID-19) is a pandemic disease of modern time with unique and rapid transmission rate and affected almost all the nations without respecting any border. Coronavirus disease 2019 (COVID-19) is arguably the biggest health crisis the world has faced in 21st century. It is an infectious disease and declared pandemic by the World Health Organization. The coronavirus disease 2019 (COVID-19) outbreak, which originated in Wuhan, China, has now spread to 192 countries and administrative regions infecting nearly 800,000 individuals of all ages as of 31 March 2020. Though most infected individuals exhibit mild symptoms including fever, upper respiratory tract symptoms, shortness of breath, and diarrhoea, or are asymptomatic altogether, severe cases of infection can lead to pneumonia, multiple organ failure, and death. Globally, at least 7900 deaths have been directly attributed to COVID19, and this number is expected to rise with the ongoing epidemic. This is particularly crucial as the current outbreak involves a new pathogen (SARS-CoV-2), on which limited knowledge exists of its infectivity and clinical profile. Research is in progress on therapeutic efficacy of various agents including anti-malarials (Chloroquine and Hydroxychloroquine), antiviral drugs, and convalescent serum of recovered patients. Unani system of medicine is one of the traditional systems of medicine which is being explored for providing preventive, supportive and rehabilitative care to patients. Unani system of medicine has a detailed description of drugs that are utilized in many infectious diseases, including respiratory infections. Immune response is essential to eliminate virus and to preclude disease progression to severe stages. Therefore, it is important to summarize the evidence regarding the preventive measures, control options such as immune-stimulator and prophylactic treatment in Unani medicine against Covid19. This review summarizes various pharmacological actions of Unani formulation Tiryaq-e-Arba in Unani literature and various reported pharmacological activities which can possibly provide prevention, control and reduction of complications of this deadly disease.

The Autism Spectrum Disorder(ASD) are distinguished by persistent deficits in social communication and social interaction and restricted and repetitive patterns of behavior. Coronaviruses are an extremely common cause of colds and other upper respiratory infections. COVID-19, short for “coronavirus disease 2019”. The fast spread of the virus that causes COVID-19 has sparked alarm worldwide. The World Health Organization (WHO) has declared this rapidly spreading coronavirus outbreak a pandemic. Most of the countries around the world are adopting social distancing to slow the spread of coronavirus. There are several possible impacts of this pandemic on the daily lives of individuals with ASD, such as worsening of dysfunctional behaviors and regression of skills already acquired in different domains of development due to the social isolation. The objective of this article is to provide guidance to parents, health and education professionals that live or work with ASD individuals during the social isolation, on how to manage interventions that can be executed in the home environment, like remote training in language and social communication skills, behavioral strategies and sensory integration activities

BACKGROUND SARS-CoV-2 and influenza are lipid-enveloped viruses with differential morbidity and mortality but shared modes of transmission. OBJECTIVE With a descriptive epidemiological framing, we assessed whether recent historical patterns of regional influenza burden are reflected in the observed heterogeneity in COVID-19 cases across regions of the world. METHODS Weekly surveillance data reported by the World Health Organization from January 2017 to December 2019 for influenza and from January 1, 2020 through October 31, 2020, for COVID-19 were used to assess seasonal and temporal trends for influenza and COVID-19 cases across the seven World Bank regions. RESULTS In regions with more pronounced influenza seasonality, COVID-19 epidemics have largely followed trends similar to those seen for influenza from 2017 to 2019. COVID-19 epidemics in countries across Europe, Central Asia, and North America have been marked by a first peak during the spring, followed by significant reductions in COVID-19 cases in the summer months and a second wave in the fall. In Latin America and the Caribbean, COVID-19 epidemics in several countries peaked in the summer, corresponding to months with the highest influenza activity in the region. Countries from regions with less pronounced influenza activity, including South Asia and sub-Saharan Africa, showed more heterogeneity in COVID-19 epidemics seen to date. However, similarities in COVID-19 and influenza trends were evident within select countries irrespective of region. CONCLUSIONS Ecological consistency in COVID-19 trends seen to date with influenza trends suggests the potential for shared individual, structural, and environmental determinants of transmission. Using a descriptive epidemiological framework to assess shared regional trends for rapidly emerging respiratory pathogens with better studied respiratory infections may provide further insights into the differential impacts of nonpharmacologic interventions and intersections with environmental conditions. Ultimately, forecasting trends and informing interventions for novel respiratory pathogens like COVID-19 should leverage epidemiologic patterns in the relative burden of past respiratory pathogens as prior information.

This chapter introduces leprosy, an infection that is still misunderstood and considered a neglected tropical disease but declining in frequency, according to the World Health Organization. The bacteria that cause leprosy, Mycobacterium leprae and Mycobacterium lepromatosis, are outlined, as well as how a relative strength of a person’s immune system determines how leprosy affects the body. Although leprosy is curable, associated stigma and disability remain common challenges for people with the disease in parts of the world. The goals and structure of the book are outlined, ten myths that still pervade society at large are listed, and the use of the word “leper” discussed. Based on World Health Organization data, the chapter also explores the frequency of leprosy today, where the infection remains a challenge, and the history of detecting and reporting evidence for leprosy in living populations. Finally, the reasons why bioarchaeologists have an interest in this infection are explored.

In December of 2019, an outbreak of a novel coronavirus flared in Wuhan, the capital city of the Hubei Province, China. The pathogen has been identified as a novel enveloped RNA beta-coronavirus named severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2). The virus SARS-CoV-2 is associated with a disease characterized by severe atypical pneumonia known as coronavirus 2019 (COVID-19). Typical symptoms of this disease include cough, fever, malaise, shortness of breath, gastrointestinal symptoms, anosmia, and, in severe cases, pneumonia.1 The high-risk group of COVID-19 patients includes people over the age of 60 years as well as people with existing cardiovascular disease and/or diabetes mellitus. Epidemiological investigations have suggested that the outbreak was associated with a live animal market in Wuhan. Within the first few months of the outbreak, cases were growing exponentially all over the world. The unabated spread of this deadly and highly infectious virus is a health emergency for all nations in the world and has led to the World Health Organization (WHO) declaring a pandemic on March 11, 2020. In this report, we consolidate and review the available clinically and preclinically relevant results emanating from in vitro animal models and clinical studies of drugs approved for emergency use as a treatment for COVID-19, including remdesivir, hydroxychloroquine, and lopinavir-ritonavir combinations. These compounds have been frequently touted as top candidates to treat COVID-19, but recent clinical reports suggest mixed outcomes on their efficacies within the current clinical protocol frameworks.

Since December 2019, when a cluster of atypical pneumonia cases were identified in Wuhan, China a new disease has spread across the world. COVID-19 has since become the biggest pandemic in a century, touching lives in almost every country in the world. At the outset of COVID-19, the World Health Organization advised for testing to become a priority so that patients with COVID-19 could be quickly identified, isolated and treated to interrupt transmission of disease. However, testing shortages have been an increasing problem in low and middle income countries. Even when tests are available, it has proved time-consuming. Therefore, we propose a symptom-based tool to assist in the diagnosis of COVID-19 management in low and middle income Countries. It is based on the symptoms that have so far been described in the literature and advises the frontline healthcare worker on how to diagnose the likelihood of having COVID-19 and separate the patient into Red (very likely), Yellow (possible) and Green (unlikely) categories.

Based on the results of a survey conducted by the World Health Organization (WHO) in 2012, the number of active smokers in the world has reached more than 1 billion people. This number is expected to continue to increase given the high prevalence of world cigarette consumption rates, while in Indonesia it is found that almost every year the number of smokers is increasing. Cigarettes containing chemicals including carbon monoxide, nicotine, tar, ammonia, arsenic, cyanide and lead (Pb) The main effect is lead that is inhaled and enters the respiratory system will also circulate throughout the tissues and organs of the body. More than 90% of lead metal absorbed by blood binds to red blood cells and results in a disruption in the process of hemoglobin synthesis. The purpose of this study is to determine the level of lead metal toxicity with an overview of smear preparations in the blood of active smokers. The research method with simple random sampling, samples taken capillary blood and making blood smear preparations that were examined with a microscope while examining the metal in the urine using Atomic Absorption Spectrophotometer (AAS). The results of the study of lead content in urine of active smokers found that the high is 0.384 mg / dl and the low lead level is 0.002 mg / dl positive containing lead in the urine with the amount of lead content exceeding the threshold and from the results of the smear dosage found that normal or normociter cell size can be obtained normal or normochrome (1/3 of the center is pale) whereas abnormalities in the cell form are teardrop cells, ovalocytes, schistocyte, this is due to the effect of lead that disrupts health especially usually occurs in haemotopoetic systems (blood formation system)
