This could have been increased by depression. Dysgeusia in elederly patients with depression should be extensively investigated in order to elucidate somatic contributing factors but it may not resolve until improvement of the depressive symptoms.The SARS-CoV-2 hyperinflammatory response is associated with high mortality. This hypothesis suggests that a deficiency of nicotinamide adenine dinucleotide (NAD+) may be the primary factor related to the SARS-Cov-2 disease spectrum and the risk for mortality, as subclinical nutritional deficiencies may be unmasked by any significant increase in oxidative stress. NAD+ levels decline with age and are also reduced in conditions associated with oxidative stress as occurs with hypertension, diabetes and obesity. These groups have also been observed to have high mortality following infection with COVID-19. Further consumption of NAD+ in a pre-existent depleted state is more likely to cause progression to the hyperinflammatory stage of the disease through its limiting effects on the production of SIRT1. [https://www.selleckchem.com/products/2-nbdg.html 2-NBDG] This provides a unifying hypothesis as to why these groups are at high risk of mortality and suggests that nutritional support with NAD+ and SIRT1 activators, could minimise disease severity if administered prophylactically and or therapeutically. The significance of this, if proven, has far-reaching consequences in the management of COVID-19 especially in third world countries, where resources and finances are limited.Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) is now a pandemic with the United States now carrying the highest number of cases and fatalities. Although vaccines and antiviral agents are the main focus of therapy, here we present a plausible hypothesis to leverage our understanding of neuroimmunomodulation to intervene in the pathophysiology of the disease to prevent death.The understanding of the renin-angiotensin system (RAS) has significantly expanded over the last two decades. The elucidation of angiotensin-converting enzyme 2 (ACE2) that converts angiotensin (Ang) II into Ang (1-7) led to the discovery of the cardio-protective axis of the RAS. In addition, novel components of the system, Angiotensin A (Ang A) and alamandine have been identified. Like Ang (1-7), alamandine is a vasodilator and can counteract the effects of Ang II by increasing nitric oxide release from the endothelium and decreasing nicotinamide adenine dinucleotide phosphate oxidase (NADPH)-related superoxide production. Theoretically, alamandine can be derived from Ang (1-7) by decarboxylation of the N-terminal aspartic acid residue to alanine, but the enzyme responsible for this is still unknown. To date, no human or mammalian enzyme with the assigned decarboxylase activity has been identified. However, several bacterial enzymes capable of converting aspartate to alanine have been reported. Therefore, we hypothesize that a bacterial enzyme, most likely present in the microbiome of the gastrointestinal tract, the heart, or systemic circulation could metabolize Ang II, and/or Ang 1-7, to Ang A and alamandine, respectively, in mammals.Management of Type 2 Diabetes (T2DM) with existing strategies of life style and pharmaceutical interventions has gained limited success as evidenced by its uncontrolled progression. Two key organs which are involved in pathophysiology of T2DM are liver and pancreas, both are the derivatives of endoderm with common precursor. In the invertebrates, hepatopancreas performs function of both liver and pancreas. It is known that derangement in glycolysis, neoglucogenesis, and glycogenolysis lead to hyperglycemia in T2DM although insulin levels are high. Several studies have reported implication of abnormal liver function in the development of metabolic syndrome i.e. T2DM. Partial hepatectomy has been shown to improve glycemic status in animal models of diabetes. This could be because liver and pancreas share same regenerating factors. These evidences suggest that abnormal liver status can impair pancreatic beta cell function and survival along with peripheral insulin resistance. We therefore hypothesize that restoring deranged liver functions may aid in the better control and management of T2DM. If found true, it may shift current intervention strategy towards liver rather than pancreas in the treatment of T2DM.At the end of 2019, the entire world has witnessed the birth of a new member of coronavirus family in Wuhan, China. Ever since, the Severe Acute Respiratory Syndrome Coronavirus 2 (SARS-CoV-2) has swiftly invaded every corner on the planet. By the end of April 2020, almost 3.5 million cases have been reported worldwide, with a death toll of about 250,000 deaths. It is currently well-recognized that patient's immune response plays a pivotal role in the pathogenesis of Coronavirus Disease 2019 (COVID-19). This inflammatory element was evidenced by its elevated mediators that, in severe cases, reach their peak in a cytokine storm. Together with the reported markers of liver injury, such hyperinflammatory state may trigger significant derangements in hepatic cytochrome P450 metabolic machinery, and subsequent modulation of drug clearance that may result in unexpected therapeutic/toxic response. We hypothesize that COVID-19 patients are potentially vulnerable to a significant disease-drug interaction, and therefore, suitable dosing guidelines with therapeutic drug monitoring should be implemented to assure optimal clinical outcomes.Novel Coronavirus (SARS CoV-2), the etiological agent for the highly contagious Corona virus disease-2019 (COVID-19) pandemic has threatened global health and economy infecting around 5.8 million people and causing over 359,200 deaths (as of 28th May 2020, https//www.worldometers.info/coronavirus/). The clinical manifestations of infected patients generally range from asymptomatic or mild to severe illness, or even death. The ability of the virus to evade the host immune response have been major reasons for high morbidity and mortality. One of the important clinical observations under conditions of critical illness show increased risk of developing disseminated intravascular coagulation. Molecular mechanisms of how SARS CoV-2 induces such conditions still remain unclear. This report describes the presence of two unique motifs in the SARS CoV-2 nucleocapsid phosphoprotein (N-protein) that can potentially interact with fibrinogen and possibly prothrombin. This is based on an established function of secretory proteins in Staphylococcus aureus (S.
