Recently, the world has been dealing with a devastating global pandemic coronavirus infection, with more than 12 million infected worldwide and over 300,000 deaths as of May 15th 2020, related to a novel coronavirus (2019-nCoV), characterized by a spherical morphology and identified through next-generation sequencing. Although the respiratory tract is the primary portal of entry of SARS-CoV-2, gastrointestinal involvement associated with nausea, vomiting and diarrhoea may also occur. No drug or vaccine has been approved due to the absence of evidence deriving from rigorous clinical trials. Increasing interest has been highlighted on the possible preventative role and adjunct treatment of lactoferrin, glycoprotein of human secretions part of a non-specific defensive system, known to play a crucial role against microbial and viral infections and exerting anti-inflammatory effects on different mucosal surfaces and able to regulate iron metabolism. In this review, analysing lactoferrin properties, we propose designing a clinical trial to evaluate and verify its effect using a dual combination treatment with local, solubilized intranasal spray formulation and oral administration. Lactoferrin could counteract the coronavirus infection and inflammation, acting either as natural barrier of both respiratory and intestinal mucosa or reverting the iron disorders related to the viral colonization.

Background: Novel Coronavirus (COVID-19), a highly contagious ssRNA +Ve sense virus that emerged in late 2019, has created a global panic. With no effective therapy available, the virus has significantly affected the world population causing millions of death. Therefore, it is the utmost need to look towards all the possible strategies to benefit the community. Objectives: In view of the current global pandemic, we tried to discuss the potential benefits of two cost-effective alternative approaches, i.e., physical exercise and yoga. Method: The editorial is based on a literature search available on PubMed, Google Scholar, and WHO portal. Search terminologies include “yoga”, “physical exercise”, “COVID-19”, “viral infections”, and a combination of these words. Results: A literature search defines yoga and physical exercise efficacy in different viral diseases, including HIV, influenza, and HSV. It ameliorates the quality of life (QoL) by improving both the physical and mental wellbeing of an individual. This is mainly done by promoting the better functioning of the immune system (increases CD4+ and CD8+ cells and reduces pro-inflammatory response). Conclusions: Regular involvement of these activities in day-to-day life may limit latent virus reactivations and reduce infection chances.

The novel coronavirus infection (SARS-CoV-2), which first appeared in Wuhan, China in December 2019, has been declared a global pandemic by WHO. COVID-19 affects people of all age groups. The disease in children is usually asymptomatic or mild compared to adults, and with a significantly lower death rates. Data on kidney damage in children with COVID-19, as well as the effect of coronavirus infection on the course of diseases of the genitourinary system, are limited, the risks of contracting a new coronavirus infection in children with significant health problems, including those with chronic kidney disease, remain uncertain. The pandemic has affected the activities of surgeons treating diseases of the urinary system in children. Since the prospects for the end of the pandemic are vague, it is necessary to formulate criteria for selecting patients who can and should be provided with routine care in the pandemic. The purpose of this review is to highlight the features of the clinical manifestations and treatment of children with COVID-19, occurring against the background of previous renal pathology or complicating its course.

Cell Expression

In December 2019, severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), a novel coronavirus (COVID-19), materialized in the city of Wuhan and quickly spread to form a global pandemic. An essential role in the immune system is undertaken by lymphocytes, which defend against bacteria, viruses, fungi, and parasites. Previous study found that very severe COVID-19 patients had suppression of the immune response enabling the virus to spread and cause more damage. This was evident by the changes in their white blood cell and lymphocyte count. Early clinical findings suggest that those suffering from severe COVID-19 have reduced numbers of lymphocytes, monocytes, and other granulocytes. One of the most efficient responses for a variety of viral infections is cellular immune response activation, especially via T cells. Viruses can be eliminated by T cytotoxic (CD8+) (Tc) in the host body, these secrete a variety of molecules, including interferons (IFNs), granzyme, and perforin. T helper (CD4+) (Th) cells help by assisting cytotoxic T cells and B cells to eliminate viral infection. CD8+ and CD4+ work together in a coordinated immune response with other constituents to primarily resolve acute viral infections, and after to produce protection against any reinfection. Also, COVID-19 causes dramatic changes in cytokine profiles and serological markers. Therefore, the subsets of immune cells and the level of the pro-inflammatory cytokines are crucial evidence to determine the severity of COVID-19. The disease severity has already been proved to be associated with the disruption in the proinflammatory chemokine response, this eventually leads to a cytokine storm and progression of cytokines release syndrome (CRS). This review aimed to demonstrate a full understanding of the alterations to the immune response by determining the T-cell expression and cytokine levels against the pathological processes of COVID-19, which can be a significant step in early treatment and diagnosis of this disease, in reduction of COVID-19 mortality cases, and to emphasize the most recent and current studies to try to identify new immuno-therapeutics for COVID-19.

Nepal is a landlocked country bordering two most populous countries, India and China. Nepal shares open border with India from three sides, east, south and west. And, in north with China, where the novel coronavirus infection (CVOVID-19) began in late December 2019. The first confirmed imported case in Nepal was reported in 2nd week of January 2020. The initial response of Nepal to COVID-19 were comparably slow but country geared efforts after it was declared a ‘global pandemic’ by WHO on 11 March, 2020. Government of Nepal’s steps from 18 March, 2020 led to partial lock down and countrywide lockdown imposed on 24 March, 2020. Government devised comprehensive plan on 27 March, 2020 for quarantine for peoples who arrived in Nepal from COVID-19 affected countries. This article covers summary of global status, South Asian Association of Regional Cooperation (SAARC) status, and Nepal’s response to contain COVID-19 infection discussed under three headings: Steps taken before and after WHO declared COVID-19 a global pandemic and lab services regarding detection of COVID-19. Nepal has documented five confirmed cases of COVID-19 till the end of March 2020, first in second week of 15 January, 2020 and 2nd case 8-weeks thereafter and 3rd case two days later, 4th on 27 March and 5th on 28 March. Four more cases detected during first week of April. Non-Pharmacological interventions like social distancing and excellent personal habits are widely practiced. Country has to enhance testing and strengthen tracing, isolation and quarantine mechanism and care of COVID-19 patients as Nepal is in risk zone because of comparably weak health system and porous borders with India. The time will tell regarding further outbreak and how it will be tackled.Keywords: COVID-19; lockdown; Nepal; pandemic; response

Care Costs

Acute respiratory infections of the upper and lower respiratory tract are currently the leading cause of human morbidity, mainly due to the seasonal rise of the incidence rates of viral infections. This results in the heavy burden of annual health care costs. The COVID-19 pandemic exacerbated the problem. The associations between respiratory viruses and bacteria are not always clear thus accounting for the diversity of the risks of the complicated course and fatal outcomes of various bacterial viral coinfections. Influenza virus is associated with the high rate of bacterial complications (in particular, during seasonal peaks). Meanwhile, this is less typical of the novel coronavirus infection. In addition, several studies demonstrate the competitive edge of SARS-CoV-2 when interacting with other respiratory viruses. The specificities of viral bacterial associations greatly affect the treatment whose inadequacy (in particular, the prescription of antibiotics) is the leading cause of the increasing antimicrobial resistance of contemporary germs. The novel coronavirus infection SARS-CoV-2 is no exception in terms of inappropriate antibiotic prescribing as occurred often in the seasonal rise of acute respiratory viral infections. The understanding of this issue, the optimization of treatment strategies, and a reduction in health care costs will allow for preserving antibiotics as a class of highly effective medications.

Background. Intussusception is the leading cause of intestinal obstruction in children under 4 years of age. Viral infections are the associated etiology in most cases, SARS-CoV-2 thereby being a plausible cause, although only 5 cases have been reported worldwide with both entities. We report a case of an infant with Intussusception and covid-19, its clinical approach, and surgical outcomes, throughout a retrospective review of electronic medical chart history with the authorization of the Ethics Committee on research of the “Hospital Universitario del Valle” and endorsement for publication. Case report. It is an 8-month-old male patient with 72 hours of fever 100.4°F; bloody diarrheal stools; episodic abdominal pain; signs of peritoneal irritation and sensation of a mass in the right quadrants of the abdomen. Intussusception confirmed by ultrasound led to surgery, with SARS-CoV-2 infection as a possible differential diagnosis. Surgical findings reported intussusception of the transverse colon, peritonitis, and intestinal ischemia of distal ileum and right colon, for which intestinal resection with consequent ileostomy and a mucous fistula was performed. Positive SARS-CoV-2 RT-PCR test result was confirmed. Pediatric intensive care unit support took place at the initial postoperative phase, and eventual intestinal, with enteral feeding tolerance at the fourth day, and respiratory improvement came off within the first week of medical and surgical treatment. Conclusion. Gastrointestinal symptoms are often the leading manifestations of COVID-19 in children, which can be isolated or as a common sign of a concomitant pathology such as intussusception, and they could also have a causal relationship.

Support Methods

In the early stages of the COVID-19 pandemic, many guidelines for the management of patients with new coronavirus infection did not include recommendations for the use of non-invasive ventilation (NIV) due to the concerns that NIV could be accompanied by high tidal volumes that could cause lung damage. In addition, there was an opinion that NIV increases the risk of spreading bioaerosol containing the SARS-CoV-2 virus. At the same time, NIV was widely used in real clinical practice in the management of severe patients with COVID-19 (in some countries, up to 60% of all respiratory support methods). The accumulated experience demonstrates that when applying NIV, the risk of contamination with viral infections is minimized with adequate use of personal protective equipment. To date, the results of a limited number of studies about effectiveness of NIV in hypoxemic acute respiratory failure (ARF) in patients with COVID-19 are available. In most studies, the need for tracheal intubation and hospital mortality, were on average, 20 – 30%, that suggests a fairly high effectiveness of NIV in ARF in patients with COVID-19.

The modern approach to the prevention and treatment of acute respiratory viral infections consists in the use of drugs that increase the body’s defenses, helping to create a barrier to the penetration of the virus. Immunomodulators exhibit a nonspecific effect in acute respiratory viral infections, which makes it possible to use them against various types of respiratory viruses without accurate laboratory diagnostics and expands clinical capabilities. In the first part of the review, the features of sodium aminodihydrophthalazinedione and the experience of its use in respiratory pathology are considered. The pandemic of the novel coronavirus infection (COVID-19), spread by the novel coronavirus SARS-CoV-2, has become a challenge to health systems around the world. The second part of the review reviews the results of the first studies on the use of sodium aminodihydrophthalazinedione for the prevention and treatment of new coronavirus infection. Recently, much attention has been paid to the long-term consequences of the postponed coronavirus infection. In the final part of the review, various aspects of the “post-COVID syndrome” are discussed and the possibilities of aminodihydrophthalazinedione sodium at the stage of rehabilitation after a coronavirus infection are discussed.

Degrees Of Severity

In December 2019, first cases of a novel coronavirus were identified in Wuhan, China. A state of global pandemic was shortly declared among a very rapid contagious spread of the virus. The causative virus was identified as the SARS-CoV-2 viruses and is genetically related to the previous SARS outbreak in 2003. The virus causes a wide clinical spectrum from mild flu-like symptoms to adult respiratory distress syndrome. Kidney involvement has been reported in several reports in patients with various degrees of severity of SARS-CoV-2 infection. As knowledge is evolving, the accurate incidence of acute kidney injury (AKI) is not known. Many questions are yet to be answered regarding the effect of epidemiological variables and comorbidities on the occurrence of AKI. Some reports have observed the occurrence of hematuria and proteinuria in a percentage of infected patients. Moreover, chronic kidney disease has not been found, in some reports to add to the adverse outcomes, an aspect that merits further exploration. Patients on regular hemodialysis may be vulnerable to coronavirus infection due to the lower status of immunity and the need for frequent attendance at health-care facilities. Due to the previous factors, prevention and mitigation of the SARS-CoV-2 virus, in this vulnerable population, constitutes a major challenge.
