While the global COVID-19 pandemic has challenged the entire humanity and health systems, it also triggered researchers to urgently perform clinical trials to assess the safety and efficacy of many agents and modalities to combat COVID-19. As of April 22, over 650 clinical studies have been registered both in USA and internationally. Results from these studies are also coming at a brisk pace in this unprecedented emergency.

Ketamine has long been used in the field of anesthesia [1]. Its rapid and long-acting analgesic effects associated with its dissociative properties have also established its use in prehospital and emergency department patients.

The currently ongoing coronavirus pandemic, the SARSCOV- 2, interchangeably referred to as the COVID-19 infection, has in a short span of time altered the ways and means of almost all of mankind. So strong has been its effect that all human activity ceased in one way or another for a considerable time, led to significant loss of life and economic drain of.

Angioimmunoblastic T cell lymphoma (AITL) is one of the most common T-cell lymphomas, second only to peripheral T-cell lymphoma not otherwise specified (PTCL-NOS). Initially AITL was considered a non-malignant lymphadenopathy with immune hyperactivation, nowadays being classified as a PTCL.

Recently, several studies and investigators have shown the beneficial effects of high dose dietary riboflavin (vitamin B2) in the treatment of keratoconus, post-refractive (LASIK, PRK & Radial Keratotomy) ectasia (with sunlight exposure) and patients treated with our own protocol (NIH Clinical Study – www.clinicaltrials.gov - # NCT 03095235) discovered significant relief for intractable migraine headaches and/or ophthalmic migraine (classic migraine visual symptoms without headache).

Five months into the COVID-19 pandemic, the U.S. death toll from the virus has now surpassed 100,000 people. Many more cases remain nationwide, while an unknown number of patients currently harbor the virus asymptomatically. While health officials are now optimistic regarding the decline in prevalence and number of deaths due to COVID-19 and the possibility of a vaccine by the fall, we cannot lose sight of the bigger picture: the next pandemic.

Our modern world is facing extraordinary circumstances while passing through a serious pandemic caused by the novel coronavirus (COVID-19) which may lead to multi-organ system failure & death. Bcell depletion could compromise antiviral immunity, which makes the safety of rituximab use in the COVID19 era unclear.

In the article, “Mental Health Framework: Coronavirus pandemic in post-Katrina New Orleans” [1], Shervington and Richardson offer recommendations about how to anticipate and address disaster-related, trauma exposures associated with the coronavirus pandemic

In January 2020, the World Health Organization (WHO) classified COVID-19 to be a Public Health Emergency of International Concern and declared it a pandemic on March 11, 2020 [1]. Over one hundred and eighty-five million people have been infected by SARS-CoV-2 and roughly four million have died worldwide so far

In the manuscript entitled “The ion channels and transporters gene expression profile indicates a shift in excitability and metabolisms during malignant progression of Follicular Lymphoma”, we reported recent advances in our understanding of how the gene expression profile of ion channels and transporters (ICT-GEP) contributes to identify specific signatures associated with Follicular Lymphoma (FL), with those FL that acquire chemoresistance after a relapsing-remitting course, and with the more aggressive Diffuse Large Cell Lymphoma (DLBCL), which in some cases represent the evolution of FLs. 

SARS-CoV-2 belongs to the genus Beta of the Coronaviridae family of enveloped single-stranded, positive-sense ribonucleic acid (RNA) with a genome length of 30,000bp. The virion is composed of various non-structural (RNA dependent RNA polymerase also known as RdRp) and structural proteins such as Spike (S), Nucleocapsid (N), Matrix (M), and Envelope (E) proteins.

The COVID-19 pandemic has provoked a global, rapid increase of cases due to the high infectivity of the etiological agent, COVID-19 virus. In February 2021, over 110 million confirmed COVID-19 cases with 1 million deaths were reported worldwide (www.who.int).

Background: The precise role of corticosteroids for treatment of coronavirus disease 2019 (COVID-19) is unclear due to lack of randomized trials. Objective: To review the therapeutic value of corticosteroids for treatment of hospitalized patients with COVID-19 with more emphasis on randomized trials. Methods: English literature search of electronic databases supplemented by manual search up to June 29, 2020. Search terms included corticosteroids, COVID-19, dexamethasone, methylprednisolone, hydrocortisone, mortality, safety. Randomized trials were the main focus of research, but observational studies were also reviewed.

Since December 2019, Severe Acute Respiratory Syndrome Coronavirus 2 (SARS-CoV-2) caused by 2019 Novel Coronavirus (2019-nCoV) has resulted in 89,000 cases of Corona Virus Disease 2019 (COVID-19), formerly known as Novel Coronavirus Pneumonia (NCP) in China, including 2,450 deaths.

Osmotic Demyelination Syndrome (ODS) is a unique process of selective demyelination and destruction of oligodendrocytes and astrocytes in specific areas of the brain that usually occurs a few days after an osmotic stress. ODS has been described most frequently in association with a rapid correction of hyponatremia, though it may occur with other electrolyte or metabolic abnormalities.

COVID-19 is the new emerging viral infection that already cause global public health problem. More than 220 countries/territories are already attacked and there are more than 17 million patients around the world. This disease was firstly reported in China then in Indochina and extended worldwide. The patient can have febrile respiratory illness and there are many asymptomatic and mild symptomatic cases. The new viral respiratory infection causes several medical and non-medical problems and it is a big challenge to be managed.

This article is an extension to our recently published article in Asian Journal of Pharmaceutical and Clinical Research, entitled “Β-Sitosterol: Isolation from Muntingia Calabura Linn. Bark Extract, Structural Elucidation, and Molecular Docking Studies as Potential Inhibitor of SARSCoV-2 Mpro (COVID-19)”[1].

At the end of 2019, a novel severe respiratory disease (coronavirus disease 2019, COVID-19) spread to Wuhan, China, it became pandemic in few months, with more than 41 million people infected worldwide as of October 2020. COVID-19 is caused by a novel virus called severe acute respiratory syndrome (SARS) CoV-2 to distinguish it from SARS-CoV that emerged in Guangdong province in China in 2003 and caused the severe clinical condition known as SARS. Like SARS-CoV, SARS- CoV-2 causes a severe inter

After one year in a pandemic, we mourn the loss of over half a million lives in the United States, and over four million worldwide, and remain concerned over the challenges facing the families of 35 million people in the United States, and 200 million worldwide, who have suffered from cases of COVID-19.

In light of the current pandemic from rapid transmission of the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2 or COVID-19) and significant morbidity, there has been inconsistent medical guidance given to the public regarding the wearing of non-medical improvised fabric masks or face coverings to reduce the transmission of COVID-19.
