Summary

On 11 March 2020, the World Health Organization declared COVID-19 a global pandemic, and the disease now affects nearly every country and region. Caused by SARS-CoV-2, COVID-19 continues nearly 18 months later to present significant challenges to health systems and public health in both hemispheres, as well as the economies of every country. The morbidity and mortality of the infection caused by SARS-CoV-2 has been significant, and various waves of disease outbreaks initially overwhelmed many hospitals and clinics and continue to do so in many countries. This influences everyone, and public health countermeasures have been dramatic in terms of their impact on employment, social systems, and mental health. This entry collection aims to gather diverse fields about COVID-19, including in epidemiology, public health, medicine, genetics, systems biology, informatics, data science, engineering, sociology, anthropology, nursing, environmental studies, statistics, and psychology.

COVID-19 Vaccination and Alcohol Consumption: Justification of Risks
Since the beginning of the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) pandemic, pharmaceutical companies and research institutions have been actively working to develop vaccines, and the mass roll-out of vaccinations against COVID-19 began in January 2021. At the same time, during lockdowns, the consumption of alcoholic beverages increased. During the peak of vaccination, consumption remained at high levels around the world, despite the gradual relaxation of quarantine restrictions. Two of the popular queries on search engines were whether it is safe to drink alcohol after vaccination and whether this will affect the effectiveness of vaccines. Many studies have been published suggesting that excessive drinking not only worsens the course of an acute respiratory distress syndrome caused by the SARS-CoV-2 virus but can also exacerbate post-COVID-19 syndrome. Despite all sorts of online speculation, there is no specific scientific data on alcohol-induced complications after vaccination in the literature. Most of the published vaccine clinical trials do not include groups of patients with a history of alcohol-use disorders.

COVID-19 Newborn Infection
It is already known how SARS-CoV-2 passed from human-to-human with the  exeption of mother-to fetous transmission of infection.  The foetus, theoretically may become infected from the mother by a blood-borne route through the placenta, during birth, through contact with maternal secretions and after birth during close contact with the mother or others. Mother-to-fetus transmission of the virus is unlikely and its mechanism is poorly understood. In a number of published studies, researchers have not based the diagnosis of COVID-19 in the newborn on developed diagnostic criteria, which makes it even more difficult to determine the frequency and pathomechanism of congenital infection. Still not much is known about complications of SARS-CoV-2 infection in pregnancy for the fetus and neonate, there are many questions that we still cannot answer. despite this, it has been possible to determine how to limit airborne transmission of the virus. By analysing the mode of delivery it is known that SARS-CoV-2 infection is not an indication for caesarean section. There are no data that provide a basis for restricting breastfeeding. It has been established that breastfeeding should be done with hand disinfection and wearing a mask.

Oral microbiome, COVID-19 Infection, and Oral hygiene
The oral microbiome plays an important role in the maintenance of immune homeostasis, whereas its association with SARS-CoV-2 infection remains under investigation. Since the oral path is one of the transmission routes for COVID-19, researchers attempt to show the relationship between the oral microbiome, COVID-19 infection, and oral hygiene.

The Interplay of Lung Cancer, COVID-19, and Vaccines
The Coronavirus disease 2019 (COVID-19) pandemic has negatively affected the treatment of malignant diseases and the development of new prodrugs worldwide. Patients with cancer are more susceptible to a higher risk of coronavirus infection and its severe complications than the general population. The lungs are the most strongly affected organs in SARS-CoV-2 infection. Additionally, within the lungs, as in other human organ tissues, angiotensin-converting enzyme 2 (ACE2) was proven to be the main host cell receptor for the binding of SARS-CoV-2. ACE2 expression is also elevated in tumor and tumor-adjacent normal tissues in patients with lung cancer, which might partially explain why patients with lung cancer are potentially at a higher risk of severe COVID-19.

SARS-CoV-2 Spike Protein-Induced Dysfunction of the NRP-1/VEGF-A Complex
Long coronavirus disease-19 (COVID-19) is a newly discovered syndrome characterized by multiple organ manifestations that persist for weeks to months, following the recovery from acute disease. Occasionally, neurological and cardiovascular side effects mimicking long COVID-19 have been reported in recipients of COVID-19 vaccines. Hypothetically, the clinical similarity could be due to a shared pathogenic role of the severe acute respiratory syndrome coronavirus-2 (SARS-CoV-2) spike (S) protein produced by the virus or used for immunization. The S protein can bind to neuropilin (NRP)-1, which normally functions as a coreceptor for the vascular endothelial growth factor (VEGF)-A. By antagonizing the docking of VEGF-A to NRP-1, the S protein could disrupt physiological pathways involved in angiogenesis and nociception. One consequence could be the increase in unbound forms of VEGF-A that could bind to other receptors. SARS-CoV-2-infected individuals may exhibit increased plasma levels of VEGF-A during both acute illness and convalescence, which could be responsible for diffuse microvascular and neurological damage.

COVID-19 Impact on Cancer-Related Care in America
COVID-19 impacted several health services, including cancer-related care. Its implications were significant due to the lapse in hospital resources, compounded by the delays stemming from the economic effects on patients’ jobs and medical coverage. Furthermore, reports suggesting an increased risk for morbidity and mortality from COVID-19 in patients with cancer and those on active cancer treatment caused additional fear and potential delays in seeking medical services.

Phage-Based Vaccines for COVID-19
Phages are highly ubiquitous biological agents, which means they are ideal tools for molecular biology and recombinant DNA technology. The development of a phage display technology was a turning point in the design of phage-based vaccines. Phages are now recognized as universal adjuvant-free nanovaccine platforms. Phages are well-suited for vaccine design owing to their high stability in harsh conditions and simple and inexpensive large-scale production. Phage vaccines induce a strong and specific humoral response by targeted phage particles carrying the epitopes of SARS-CoV-2.

PENG-Based Non-Invasive Medical Sensors
Piezoelectric nanogenerators (PENGs) not only are able to harvest mechanical energy from the ambient environment or body and convert mechanical signals into electricity but can also inform people about pathophysiological changes and communicate this information using electrical signals, thus acting as medical sensors to provide personalized medical solutions to patients.

Beneficial Effects of Thymoquinone against COVID-19
In order to overcome the serious complications associated with COVID-19 and to prevent SARS-CoV-2 entry into the host cell, it is necessary to repurpose drugs with a broad medicinal application as soon as they become available. It is in this pattern that Nigella sativa seeds manifest their extensive therapeutic effects, which have been reported to be particularly effective in the treatment of skin diseases, jaundice, and gastrointestinal problems. One important component of these seeds is thymoquinone (TQ), which has a wide range of beneficial properties, including antioxidant and anti-inflammatory properties, as well as antibacterial and parasitic properties, in addition to anticarcinogenic, antiallergic, and antiviral properties.
