Intensity and incidence involving burnout symptoms inside paediatric extensive treatment healthcare professionals: A planned out evaluate.
There is a growing body of evidence on the significance of interactions between comorbidities, their treatments and COVID-19 clinical phenotypes. The hypothesis explored herein is that pharmaceutical compounds currently in use are affecting COVID-19 susceptibility and phenotypes by overlapping transcriptional networks. Using two distinct SARS-CoV-2 - host interactomes, gene set enrichment analysis is used to discover compounds and assorted gene signatures derived from SARS-CoV-2 interactomes. Micronutrients, antiplatelets, ACE2 inhibitors, NSAIDs, corticosteroids and tyrosine kinase inhibitors are among the compounds discovered. Considering the implication of their associated comorbidities such as diabetes and cardiovascular disease that are associated with severe COVID-19, this study outlines the need to consider specific compounds as modulators of the observed COVID-19 spectrum. Furthermore, given that micronutrient trafficking may be targeted by viral processes, and display synergism with other enriched compounds, such as statins, studies assessing their levels prior and during infection are more than warranted.The experimental observation that an increase in calcium above micromolar concentrations results in a slowing or stopping of anaphase-A motion is evidence for an electrostatic mechanism for poleward mitotic chromosome motions. Specifically, higher concentrations of doubly-charged calcium ions screen negative charges at microtubule free "plus" ends at kinetochores and at centrosomes. These structures normally interact with positive charges at kinetochores and positively charged microtubule free ends vicinal to centrosomes to generate poleward force. As with calcium ions, doubly-charged zinc cations can also shield these negative charges, thereby interfering with force generation for anaphase-A chromosome motion, aborting mitosis. Experimental evidence reveals that dysregulation of free cytosolic zinc homeostasis contributes to cancerous transformation. Treatment of cancers by increasing zinc concentration has unknowingly been accomplished by utilizing zinc ionophores to facilitate zinc transport across the plasma membrane, revealing an inverse relationship between malaria incidence - and malaria treatment with zinc ionophores - and cancer mortality. Here we hypothesize a biophysical mechanism for cancer therapy employing zinc supplementation enhanced by zinc ionophores.Obese individuals seem to be at the highest risk of contracting COVID-19 infection. Furthermore, severity of morbidity and mortality rates are higher in the developed world as compared to the developing world. One probable reason for this difference could be the difference in living conditions and exposure to other infections. Secondly, the difference in food especially, alcohol use may have deteriorating effects superimposed with obesity. Our hypothesis suggests that a combination of alcohol consumption and obesity causes low immunity and makes the individual prone to develop 'cytokine storm' and 'acute respiratory distress syndrome'; the hallmark of COVID-19 mortality and morbidity. Thus, we propose that reducing any one trigger can have a beneficial effect in combating the disease severity.COVID-19 is caused by a new strain of coronavirus called SARS-coronavirus-2 (SARS-CoV-2), which is a positive sense single strand RNA virus. In humans, it binds to angiotensin converting enzyme 2 (ACE2) with the help a structural protein on its surface called the S-spike. Further, cleavage of the viral spike protein (S) by the proteases like transmembrane serine protease 2 (TMPRSS2) or Cathepsin L (CTSL) is essential to effectuate host cell membrane fusion and virus infectivity. COVID-19 poses intriguing issues with imperative relevance to clinicians. The pathogenesis of GI symptoms, diabetes-associated mortality, and disease recurrence in COVID-19 are of particular relevance because they cannot be sufficiently explained from the existing knowledge of the viral diseases. Tissue specific variations of SARS-CoV-2 cell entry related receptors expression in healthy individuals can help in understanding the pathophysiological basis the aforementioned collection of symptoms. ACE2 mediated dysregulation of sodium dependent glucose transporter (SGLT1 or SLC5A1) in the intestinal epithelium also links it to the pathogenesis of diabetes mellitus which can be a possible reason for the associated mortality in COVID-19 patients with diabetes. High expression of ACE2 in mucosal cells of the intestine and GB make these organs potential sites for the virus entry and replication. Continued replication of the virus at these ACE2 enriched sites may be a basis for the disease recurrence reported in some, thought to be cured, patients. Based on the human tissue specific distribution of SARS-CoV-2 cell entry factors ACE2 and TMPRSS2 and other supportive evidence from the literature, we hypothesize that SARS-CoV-2 host cell entry receptor-ACE2 based mechanism in GI tissue may be involved in COVID-19 (i) in the pathogenesis of digestive symptoms, (ii) in increased diabetic complications, (iii) in disease recurrence.Treatment-resistant depression (TRD) remains one of the major psychiatric challenges worldwide. Search for non-monoaminergic agents, possibly effective in treatment of TRD is of prime importance. read more One of those agents is ketamine - a dissociative, anesthetic drug exhibiting a fast antidepressant action in patients with TRD. Concurrently, anhedonia appears to be significant symptom domain with far-reaching impact on course of treatment. There is data demonstrating that abnormal copper levels might be associated with symptoms of depression. As there is common denominator in ketamine and copper role in neurotransmission this paper is to explore the associations of blood copper levels and psychometric measures in patients with TRD in course of major depressive disorder (MDD) and bipolar disorder (BP), focusing on anhedonia measured with Snaith-Hamilton Pleasure Scale (SHAPS) score.Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) is causing the current pandemic of coronavirus disease 2019 (COVID-19) that has killed nearly one million people so far. While this is a respiratory virus, surprisingly, it has been recognized that patients with cardiovascular disease are likely to be affected severely and die of COVID-19. This phenomenon cannot be explained by the generally accepted logic that the SARS-CoV-2 infection/replication is the sole determinant of the actions of the virus to define the fate of host cells. I herein propose the viral protein fragment theory of COVID-19 pathogenesis based on my observations in cultured human vascular cells that SARS-CoV-2 spike protein can activate cell signaling events without the rest of the viral components. It is generally thought that SARS-CoV-2 and other single-stranded RNA viruses attach to the host cells through the interactions between surface proteins of the viral capsid and the host cell receptors; the fusion and the entry of the viral components, resulting in the replication of the viruses; and the host cell responses are the consequence of these events.
